+
+<p>The function name verification processing for external input can effectively prevent the leakage of sensitive information.</p>

+<overview>
+<p>The software uses external input as the function name to wrap JSON data and return it to the client as a request response. When there is a cross-domain problem, 
+there is a problem of sensitive information leakage.</p>
+
+</overview>
+<recommendation>
+
+<p>Adding `Referer` or random `token` verification processing can effectively prevent the leakage of sensitive information.</p>
+
+</recommendation>
+<example>
+
+<p>The following example shows the case of no verification processing and verification processing for the external input function name.</p>

-<overview>
-<p>The software uses external input as the function name to wrap JSON data and return it to the client as a request response. When there is a cross-domain problem, 
-there is a problem of sensitive information leakage.</p>
-
-</overview>
-<recommendation>
-
-<p>The function name verification processing for external input can effectively prevent the leakage of sensitive information.</p>
-

+# Current status (Feb 2021)
+
+This should be kept up to date; the world is moving fast and protocols are being broken.
+
+## Protocols
+
+- All versions of SSL are insecure
+- TLS 1.0 and TLS 1.1 are insecure
+- TLS 1.2 have some issues. but TLS 1.3 is not widely supported
+
+## Conection methods
+
+- `ssl.wrap_socket` is creating insecure connections, use `SSLContext.wrap_socket` instead. [link](https://docs.python.org/3/library/ssl.html#ssl.wrap_socket)
+    > Deprecated since version 3.7: Since Python 3.2 and 2.7.9, it is recommended to use the `SSLContext.wrap_socket()` instead of `wrap_socket()`. The top-level function is limited and creates an insecure client socket without server name indication or hostname matching.
+- Default consteructors are fine, a sluent api is used to constrain possible protocols later.
+
+## Current recomendation
+
+TLS 1.2 or TLS 1.3
+
+## Queries
+
+- `InsecureProtocol` detects uses of insecure protocols.
+- `InsecureDefaultProtocol` detect default constructions, this is no longer unsafe.

+<p>The following examples show the bad case and the good case respectively. Bad case, such as <code>bad1</code> to <code>bad7</code>,

+
+<overview>
+<p>
+Jakarta Expression Language (EL) is an expression language for Java applications.
+There are a single language specification and multiple implementations
+such as Glassfish, Juel, Apache Commons EL, etc.
+The language allows invocation of methods available in the JVM.
+If an expression is built using attacker-controlled data,
+and then evaluated, then it may allow the attacker to run arbitrary code.
+</p>
+</overview>
+
+<recommendation>
+<p>
+It is generally recommended to avoid using untrusted data in an EL expression.
+Before using untrusted data to build an EL expressoin, the data should be validated
+to ensure it is not evaluated as expression language. If the EL implementaion offers
+configuring a sandbox for EL expression, they should be run in a restircitive sandbox
+that allows accessing only explicitly allowed classes. If the EL implementation
+does not allow sandboxing, consider using other expressiong language implementations
+with sandboxing capabilities such as Apache Commons JEXL or the Spring Expression Language.
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example shows how untrusted data is used to build and run an expression
+using the JUEL interpreter:
+</p>
+<sample src="UnsafeExpressionEvaluationWithJUEL.java" />
+
+<p>
+JUEL does not allow to run expression in a sandbox. To prevent running arbitrary code,
+incoming data has to be checked before including to an expression. The next example
+uses a Regex pattern to check whether a user tries to run an allowed exression or not:
+</p>
+<sample src="SaferExpressionEvaluationWithJUEL.java" />
+

Subject: [PATCH 0039/1662] Python: Clean up `basicStoreStep`

Moves the `flowsTo` logic into the shared implementation, so that
`TypeTrackingPrivate` only has to define the shape of immediate store
steps.

Also cleans up the documentation to talk a bit more about what
`content` can represent, and what caveats there are.

Subject: [PATCH 0052/1662] Fix comments. This induced fixing the code, since
 things were wired up wrongly. Currently the only implementation of
 `insecure_connection_creation` is `ssl.wrap_socket`, which is also the sole
 target of  py/insecure-default-protocol`, so perhaps this part should be
 turned off?

+  </overview>
+
+  <recommendation>
+    <p>In case user input must compose an LDAP query, it should be escaped in order to avoid a malicious user supplying special characters that change the actual purpose of the query. To do so, functions that ldap frameworks provide such as <code>escape_filter_chars</code> should be applied to that user input.

+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade

+     *
+     * <p>This is a convenience method: the string argument is first BASE64-decoded to a byte array and this resulting
+     * byte array is used to invoke {@link #signWith(SignatureAlgorithm, byte[])}.</p>
+     *
+     * <h4>Deprecation Notice: Deprecated as of 0.10.0, will be removed in the 1.0 release.</h4>
+     *
+     * <p>This method has been deprecated because the {@code key} argument for this method can be confusing: keys for
+     * cryptographic operations are always binary (byte arrays), and many people were confused as to how bytes were
+     * obtained from the String argument.</p>
+     *
+     * <p>This method always expected a String argument that was effectively the same as the result of the following
+     * (pseudocode):</p>
+     *
+     * <p>{@code String base64EncodedSecretKey = base64Encode(secretKeyBytes);}</p>
+     *
+     * <p>However, a non-trivial number of JJWT users were confused by the method signature and attempted to
+     * use raw password strings as the key argument - for example {@code signWith(HS256, myPassword)} - which is
+     * almost always incorrect for cryptographic hashes and can produce erroneous or insecure results.</p>
+     *
+     * <p>See this
+     * <a href="https://stackoverflow.com/questions/40252903/static-secret-as-byte-key-or-string/40274325#40274325">
+     * StackOverflow answer</a> explaining why raw (non-base64-encoded) strings are almost always incorrect for
+     * signature operations.</p>
+     *
+     * <p>To perform the correct logic with base64EncodedSecretKey strings with JJWT >= 0.10.0, you may do this:
+     * <pre><code>
+     * byte[] keyBytes = {@link Decoders Decoders}.{@link Decoders#BASE64 BASE64}.{@link Decoder#decode(Object) decode(base64EncodedSecretKey)};
+     * Key key = {@link Keys Keys}.{@link Keys#hmacShaKeyFor(byte[]) hmacShaKeyFor(keyBytes)};
+     * jwtBuilder.signWith(key); //or {@link #signWith(Key, SignatureAlgorithm)}
+     * </code></pre>

+     * use raw password strings as the key argument - for example {@code setSigningKey(myPassword)} - which is
+     * almost always incorrect for cryptographic hashes and can produce erroneous or insecure results.</p>
+     *
+     * <p>See this
+     * <a href="https://stackoverflow.com/questions/40252903/static-secret-as-byte-key-or-string/40274325#40274325">

+<overview>
+<p>The software obtains the original client IP address through the http header <code>X-Forwarded-For</code>, which is used to ensure 
+security or track it in the log for statistical or other reasons. Attackers can use <code>X-Forwarded-For </code> Spoofing software.</p>
+
+</overview>
+<recommendation>
+
+<p>When the software is not using a proxy server, get the last ip.</p>
+
+</recommendation>
+<example>
+
+<p>The following examples show the bad case and the good case respectively. Bad case, such as <code>bad1</code> to <code>bad2</code>. 
+In the <code>bad1</code> method, the value of <code>X-Forwarded-For</code> in <code>header</code> is split, and the first value of 
+the split array is obtained. Good case, such as <code>good1</code>, split the value of <code>X-Forwarded-For</code> in <code>header</code> 
+and get the last value of the split array.</p>

-  <overview>
-    <p>If an LDAP query is built by a not sanitized user-provided value, a user is likely to be able to run malicious LDAP queries.</p>
-  </overview>
+<overview>
+<p>If an LDAP query or DN is built using string concatenation or string formatting, and the
+components of the concatenation include user input without any proper sanitization, a user 
+is likely to be able to run malicious LDAP queries.</p>
+</overview>
+
+<recommendation>
+<p>If user input must be included in an LDAP query or DN, it should be escaped to
+avoid a malicious user providing special characters that change the meaning
+of the query. In Python2, user input should be escaped with <code>ldap.dn.escape_dn_chars</code> 
+or <code>ldap.filter.escape_filter_chars</code>, while in Python3, user input should be escaped with 
+<code>ldap3.utils.dn.escape_rdn</code> or <code>ldap3.utils.conv.escape_filter_chars</code>
+depending on the component tainted by the user. A good practice is to escape filter characters 
+that could change the meaning of the query (https://tools.ietf.org/search/rfc4515#section-3).</p>
+</recommendation>
+
+<example>
+<p>In the following examples, the code accepts both <code>username</code> and <code>dc</code> from the user, 
+which it then uses to build a LDAP query and DN.</p>
+
+<p>The first and the second example uses the unsanitized user input directly
+in the search filter and DN for the LDAP query.
+A malicious user could provide special characters to change the meaning of these
+components, and search for a completely different set of values.</p>
 
-  <recommendation>
-    <p>In case user input must compose an LDAP query, it should be escaped in order to avoid a malicious user supplying special characters that change the actual purpose of the query. To do so, functions that ldap frameworks provide such as <code>escape_filter_chars</code> should be applied to that user input.
-  <recommendation>
+<sample src="examples/example_bad1.js" />
+<sample src="examples/example_bad2.js" />
 
+<p>In the third and four example, the input provided by the user is sanitized before it is included in the search filter or DN. 
+This ensures the meaning of the query cannot be changed by a malicious user.</p>

+
+<overview>
+<p> A JWT consists of three parts: header, payload, and signature.
+The <code>io.jsonwebtoken.jjwt</code> library is one of many libraries used for working with JWTs.
+It offers different methods for parsing tokens like <code>parse</code>, <code>parseClaimsJws</code>, and <code>parsePlaintextJws</code>.
+The last two correctly verify that the JWT is properly signed.
+This is done by computing the signature of the combination of header and payload and
+comparing the locally computed signature with the signature part of the JWT.
+</p>
+<p>
+Therefore it is necessary to provide the <code>JwtParser</code> with a key that is used for signature validation.
+Unfortunately the <code>parse</code> method <b>accepts</b> a JWT whose signature is empty although a signing key has been set for the parser.
+This means that an attacker can create arbitrary JWTs that will be accepted.
+</p>
+</overview>
+<recommendation>
+
+<p>Always verify the signature by using either the <code>parseClaimsJws</code> and <code>parsePlaintextJws</code> methods or
+by overriding the <code>onPlaintextJws</code> or <code>onClaimsJws</code> of <code>JwtHandlerAdapter</code>.
+</p>
+
+</recommendation>
+<example>
+
+<p>The following example shows four cases where a signing key is set for a parser.
+In the first bad case the <code>parse</code> method is used which will not validate the signature.
+The second bad case uses a <code>JwtHandlerAdapter</code> where the <code>onPlaintextJwt</code> method is overriden so it will not validate the signature.
+The third and fourth good cases use <code>parseClaimsJws</code> method or override the <code>onPlaintextJws</code> method.
+</p>

-<p>In some situations, after code refactoring, parts of the old constructs may remain. They are correctly accepted by the compiler, but can critically affect program execution. For example, if you switch from `do {...} while ();` to `while () {...}` with errors, you run the risk of running out of resources. These code snippets look suspicious and require the developer's attention.</p>
+<p>In some situations, after code refactoring, parts of the old constructs may remain. They are correctly accepted by the compiler, but can critically affect program execution. For example, if you switch from `do {...} while ();` to `while () {...}` forgetting to remove the old construct completely, you get `while(){...}while();` which may be vulnerable.

Subject: [PATCH 0197/1662] Python: Fix bad join in `total_cost`

The recent change to `appliesTo` lead to a perturbation in the join
order of this predicate, which resulted in a cartesian product between
`call` and `ctx` being created (before being filtered by `appliesTo`).

By splitting the intermediate result into its own helper predicate,
suitably marked to prevent inlining/magic, we prevent this from
happening again.

Subject: [PATCH 0199/1662] Python: Prevent bad join in `isinstanceEvaluatesTo`

In some cases, we were joining the result of `val.getClass()` against
the first argument of `Types::improperSubclass` before filtering out the
vast majority of tuples by the call to `isinstance_call`.

To fix this, we let `isinstance_call` take care of figuring out the
class of the value being tested. As a bonus, this cleans up the only
other place where `isinstance_call` is used, where we _also_ want to
know the class of the value being tested in the `isinstance` call.

Subject: [PATCH 0225/1662] Python: Port taint tests to use inline expectations

The meat of this PR is described in the new python/ql/test/experimental/meta/InlineTaintTest.qll file:

> Defines a InlineExpectationsTest for checking whether any arguments in
> `ensure_tainted` and `ensure_not_tainted` calls are tainted.
>
> Also defines query predicates to ensure that:
> - if any arguments to `ensure_not_tainted` are tainted, their annotation is marked with `SPURIOUS`.
> - if any arguments to `ensure_tainted` are not tainted, their annotation is marked with `MISSING`.
>
> The functionality of this module is tested in `ql/test/experimental/meta/inline-taint-test-demo`.

Subject: [PATCH 0227/1662] Python: Disallow `PostUpdateNode` as
 `LocalSourceNode`

Previously, in cases like

```python
def foo(x):
    x.bar()
    x.baz()
    x.quux()
```

we would have flow from the first `x` to each use _and_ flow from the
post-update node for each method call to each subsequent use, and all
of these would be `LocalSourceNode`s. For large functions with the above
pattern, this would lead to a quadratic blowup in `hasLocalSource`.

With this commit, only the first of these will count as a
`LocalSourceNode`, and the blowup disappears.

 `DispatchMethodOrAccessorCall::getAViableOverrider()`

In addition to improved performance, the analysis no longer applies a closed-world
assumption to type parameters. That is, if the type of a receiver is a type parameter,
then the call may target any method of a compatible receiver type, not just the
types that actually instantiate the type parameter.

Subject: [PATCH 0239/1662] Revert "Revert "C++: Work around extractor issue
 CPP-383""

**Revert the revert** of the workaround for CFG issues when a
`FunctionCall` has a `getTarget` that does not exist. While we've fixed
the main cause of the problem, it can apparently still happen in rare
cases as a result of extractor crashes.

This reverts commit ee5eaef5e48ba3802fb118c56bd9aae0ef2ac805.

+
+<overview>
+<p>
+Constructing a regular expression with unsanitized user input is dangerous as a malicious user may
+be able to modify the meaning of the expression. In particular, such a user may be able to provide
+a regular expression fragment that takes exponential time in the worst case, and use that to
+perform a Denial of Service attack.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Before embedding user input into a regular expression, use a sanitization function
+to escape meta-characters that have special meaning.
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example shows a HTTP request parameter that is used to construct a regular expression:
+</p>
+<sample src="RegexInjection.java" />
+<p>
+In the first case the user-provided regex is not escaped.
+If a malicious user provides a regex that has exponential worst case performance,
+then this could lead to a Denial of Service.
+</p>
+<p>
+In the second case, the user input is escaped using <code>escapeSpecialRegexChars</code> before being included
+in the regular expression. This ensures that the user cannot insert characters which have a special
+meaning in regular expressions.
+</p>
+</example>

Subject: [PATCH 0271/1662] C#: Various data-flow performance tweaks

- Cache `DataFlowCall::getEnclosingCallable()`.
- Cache `ParameterNode`.
- Cache `ArgumentNode`.
- Force proper join-orders for uses of `getNodeType()`.
- Inline `localFlow` to prevent calculating full TC.

+
+<overview>
+<p>
+Apache Groovy is a powerful, optionally typed and dynamic language, 
+with static-typing and static compilation capabilities.
+
+It integrates smoothly with any Java program, 
+and immediately delivers to your application powerful features, 
+including scripting capabilities, Domain-Specific Language authoring, 
+runtime and compile-time meta-programming and functional programming.
+
+If a Groovy script is built using attacker-controlled data, 
+and then evaluated, then it may allow the attacker to achieve RCE.
+</p>
+</overview>
+
+<recommendation>
+<p>
+It is generally recommended to avoid using untrusted input in a Groovy evaluation.
+If this is not possible, use a sandbox solution. Developers must also take care that Groovy
+compile-time metaprogramming can also lead to RCE: it is possible to achieve RCE by compiling
+a Groovy script (see the article "Abusing Meta Programming for Unauthenticated RCE!" linked below).
+
+Groovy's <code>SecureASTCustomizer</code> allows securing source code by controlling what code constructs are permitted. 
+This is typically done when using Groovy for its scripting or domain specific language (DSL) features.
+The fundamental problem is that Groovy is a dynamic language, yet SecureASTCustomizer works by looking at Groovy AST statically.
+
+This makes it very easy for an attacker to bypass many of the intended checks
+(see https://kohsuke.org/2012/04/27/groovy-secureastcustomizer-is-harmful/).
+Therefore, besides SecureASTCustomizer, runtime checks are also necessary before calling Groovy methods
+(see https://melix.github.io/blog/2015/03/sandboxing.html).
+
+It is also possible to use a block-list method, excluding unwanted classes from being loaded by the JVM. 
+This method is not always recommended, because block-lists can be bypassed by unexpected values.
+
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example uses untrusted data to evaluate a Groovy script.
+</p>
+<sample src="GroovyInjectionBad.java" />
+
+<p>
+The following example uses classloader block-list approach to exclude loading dangerous classes.

+   * Holds if the function in `succ` forwards all its arguments to a call to `pred`.
+   * This can thus be seen as a step `pred -> succ` used for tracking function values
+   * through "wrapper functions", since the `succ` function partially replicates behavior of `pred`.
+   *
+   * This is similar to `functionForwardingStep` except the innermost forwarding call does not
+   * need flow to the return value; this can be useful for tracking callback-style functions
+   * where the result tends to be unused.
+   *
+   * Examples:
+   * ```js
+   * function f(x, callback) {
+   *   g(x, callback); // step: g -> f
+   * }
+   *
+   * function doExec(x, callback) {

Subject: [PATCH 0292/1662] Python: Use `LocalSourceNode` throughout `step`

This commit does a lot of stuff all at once, so here are the main
highlights:

In `TypeTracker.qll`, we change `StepSummary::step` to step only between
source nodes. Because reads and writes of global variables happen in two
different (jump) steps, this requires the intermediate
`ModuleVariableNode` to _also_ be a `LocalSourceNode`, and we therefore
modify the charpred for that class accordingly. (This also means
changing a few of the tests to account for these new source nodes.)

In addition, we change `TypeTracker::step` to likewise step between
local source nodes.

Next, to enable the use of the `track` convenience method on nodes, we
add some pragmas to `TypeTracker::step` that prevent bad joins from
occurring. With this, we can eliminate all of the manual type tracker
join predicates.

Next, we observe that because `StepSummary::step` now uses `flowsTo`, it
automatically encapsulates all local-flow steps. In particular this
means we do not have to use `typePreservingStep` in `smallstep`, but can
use `jumpStep` directly. A similar observation applies to
`TypeTracker::smallstep`.

Having done this, we no longer need `typePreservingStep`, so we get rid
of it.

+* The predicates `StepSummary::step` and `TypeTracker::step` in `TypeTracker.qll` have been changed
+  to use the more restrictive type `LocalSourceNode` for their second argument. For cases where
+  stepping between non-`LocalSourceNode`s is required, the `StepSummary::smallstep` predicate may be
+  used instead.

Subject: [PATCH 0294/1662] Python: Simplify charpred for `LocalSourceNode`

The somewhat convoluted `comes_from_cfgnode` was originally introduced
in order to have local sources for instances of global variables. This
was needed because global variables have an implicit "scope entry" SSA
definition that flows to the first actual use of the variable (and so
would not fit the strict "has no incoming flow" definition of a local
source node).

However, a subsequent change means that we include all global variable
reads anyway, and so the old definition is no longer needed.

(See commit 3fafb47b1680fc7fb42418a1ca6816986262ab05 for further
context.)

Subject: [PATCH 0299/1662] Python: `ModuleVariableNode`s are not API uses

This caused some suprising test changes, where suddenly we had flow from
a `ModuleVariableNode` (as a `RemoteFlowSource`) to a sink. This of
course makes little sense, so instead we simply exclude these nodes as
uses in the first place.

Subject: [PATCH 0300/1662] Python: Move `track`/`backtrack` to
 `LocalSourceNode`

This is merely making explicit what was implicitly enforced. The move
to change the return type of `step` already meant that `this` and
`result` had to be `LocalSourceNode`. By moving these methods to their
rightful place, we should hopefully avoid a bit of suprising behaviour.

Subject: [PATCH 0301/1662] Python: Prevent bad joins in `TypeBackTracker`

Perhaps unsurprisingly, the join orderer was eager and willing to find
the wrong join order in this predicate as well. Applying a similar
fix to the one used in `TypeTracker::step` fixes the problem.

Subject: [PATCH 0324/1662] Python: Extract SensitiveDataHeuristics to be
 shared with JS

Initially I had called `nameIndicatesSensitiveData` for `maybeSensitiveName`,
which made the relationship with `maybeSensitive` and `notSensitive` quite
strange -- and therefore I added the more informative `maybeSensitiveRegexp` and
`notSensitiveRegexp`.

Although I'm no longer using `maybeSensitiveName`, and I no longer have a strong
argument for making this name change, I still like it. If someone thinks this is
a terrible idea, I'm happy to change it though :+1:

Subject: [PATCH 0329/1662] JS: Rewrite to use nameIndicatesSensitiveData

I added this predicate mostly because it was nice with an easy shortcut for it,
but also since I spotted the `CredentialsFunctionName` not checking agaisnt the
regexps in `notSensitive`, which looked suspicious. So the main goal of adding
`nameIndicatesSensitiveData` is that you don't accidentially forget to ensure
that the name doesn't match against `notSensitve`.

+Access paths
+------------
+
+When multiple property accesses are chained together they form what's called an "access path".
+
+To identify nodes based on access paths, use the following predicates in `AccessPath <https://codeql.github.com/codeql-standard-libraries/javascript/semmle/javascript/GlobalAccessPaths.qll/module.GlobalAccessPaths$AccessPath.html>`__ module:
+
+- AccessPath::`getAReferenceTo <https://codeql.github.com/codeql-standard-libraries/javascript/semmle/javascript/GlobalAccessPaths.qll/predicate.GlobalAccessPaths$AccessPath$getAReferenceTo.2.html>`__ -- find nodes that refer to the given access path

Subject: [PATCH 0338/1662] Python: Remove `typePreservingStep`

This requires a bit of explanation, so strap in.

Firstly, because we use `LocalSourceNode`s as the start and end points
of our `StepSummary::step` relation, there's no need to include
`simpleLocalFlowStep` (via `typePreservingStep`) in `smallstep`. Indeed,
since the successor node for a `step` is a `LocalSourceNode`, and local
sources never have incoming flow, this is entirely futile -- we can find
values for `mid` and `nodeTo` that satisfy the body of `step`, but
`nodeTo` will never be a `LocalSourceNode`.

With this in mind, we can simplify `smallstep` to only refer to
`jumpStep`.

This then brings the other uses of `typePreservingStep` into question.
The only other place we use this predicate is in the `TypeTracker` and
`TypeBackTracker` `smallstep` predicates. Note, however, that here we
no longer need `jumpStep` to be part of `typeTrackingStep` (as it is
already accounted for in `StepSummary::smallstep`) so we can simplify
to `simpleLocalFlowStep`. At this point, `typePreservingStep` is unused.

Finally, because of the way `smallstep` is used in `step` (inside
`StepSummary`), `nodeTo` must always be a `LocalSourceNode`, so I have
propagated this restriction to `smallstep` as well. We can always lift
this restriction later, but for now it seems like it's likely to cause
fewer surprises to have made this explicit.

Subject: [PATCH 0339/1662] Python: Prevent bad joins

Adds a few unbinds to prevent bad joins from occurring.

Firstly, we never want to join `StepSummary::step` with
`TypeTracker::append` on `summary` as the first join, as the resulting
relation is absolutely massive. So we decouple the two occurrences of
`summary` by unbinding each of them.

Secondly, in some cases the node we're stepping to (`nodeTo` for type
trackers, `nodeFrom` for type backtrackers) will get joined eagerly
with the typetracker one is defining, and again this produces an
uncomfortably large intermediate join. A bit of unbinding prevents this
as well.

Subject: [PATCH 0358/1662] C++: Isolate models from AST dataflow's
 reference/object conflation

`DataFlowFunction` models treat references a pointers - an explicit level of indirection. The AST dataflow library generally treats references as if they were the referred-to object. This commit removes a workaround in the dataflow model for unary `operator*` on smart pointers, and makes the AST dataflow library adjust the results of querying the model so that a returned reference only gets flow that was modeled as going to the dereference of the return value.

This fixes some missing flow in IR dataflow, and recovers some (presumably) missing reverse taint flow in AST taint tracking as well.

Subject: [PATCH 0393/1662] Python: Add CryptographicOperation Concept

Using getAnInput also aligns better with Decoding/Encoding.

+These tests are a copy of the tests in [../cryptodome](../cryptodome) with `Cryptodome` replaced by `Crypto`.
+
+You can run the following command to update the tests:
+
+```sh
+rm *.py && cp ../cryptodome/*.py . && sed -i -e 's/Cryptodome/Crypto/' *.py
+```
+
+The original [`pycrypto` PyPI package](https://pypi.org/project/pycrypto/) that provided the `Crypto` Python package has not been updated since 2013, so it is reasonable to assume that people will use the replacement [`pycryptodome` PyPI package](https://pypi.org/project/pycryptodome/) that has a (mostly) compatible API.
+
+The pycryptodome functionality is also available in the [`pycryptodomex` PyPI package](https://pypi.org/project/pycryptodomex/) which provides the `Cryptodome` Python package.
+
+To ensure our modeling actually covers _both_ ways of importing the same functionality, we have this convoluted test setup.

Date: Tue, 2 Mar 2021 09:53:09 +0100
Subject: [PATCH 0398/1662] Python: Add MISSING:
 CryptographicOperationAlgorithm annotations

For RSA it's unclear what the algorithm name should even be. Signatures based on
RSA private keys with PSS scheme is ok, but with pkcs#1 v1.5 they are
weak/vulnerable. So clearly just putting RSA as the algorithm name is not enough
information...

and that problem is also why I wanted to do this commit separetely (to call
extra atten to this).

Subject: [PATCH 0400/1662] Python: Model encrypt/decrypt in cryptography
 package

I introduced a InternalTypeTracking module, since the type-tracking code got so
verbose, that it was impossible to get an overview of the relevant predicates.
(this means the "first" type-tracking predicate that is usually private, cannot
be marked private anymore, since it needs to be exposed in the private module.

Subject: [PATCH 0404/1662] Python: Move framework test-files out of
 experimental

This PR was rebased on newest main, but was written a long time ago when all the
framework test-files were still in experimental. I have not re-written my local
git-history, since there are MANY updates to those files (and I dare not risk
it).

+     <overview>
+          <p>
+               Using a broken or weak cryptographic hash function can leave data
+               vulnerable, and should not be used in security related code.
+          </p>
+
+          <p>
+               A strong cryptographic hash function should be resistant to:
+          </p>
+          <ul>
+               <li>
+                    pre-image attacks: if you know a hash value <code>h(x)</code>,
+                    you should not be able to easily find the input <code>x</code>.
+               </li>
+               <li>
+                    collision attacks: if you know a hash value <code>h(x)</code>,
+                    you should not be able to easily find a different input <code>y</code>
+                    such that hash value is the same <code>h(x) = h(y)</code>.
+               </li>
+          </ul>
+          <p>
+               In cases with a limited input space, such as for passwords, the hash
+               function also needs to be computationally expensive to be resistant to
+               brute-force attacks.
+          </p>
+
+          <p>
+               As an example, both MD5 and SHA-1 is known to be vulnerable to collision attacks.
+          </p>
+
+          <p>
+               Since it's OK to use a weak cryptographic hash function in a non-security
+               context, this query only alerts when these are used to hash sensitive
+               data (such as passwords, certificates, usernames).
+          </p>
+
+          <p>
+               Use of broken or weak cryptographic algorithms that are not hashing algorithms, is
+               handled by the <code>py/weak-cryptographic-algorithm</code> query.
+          </p>
+
+     </overview>
+     <recommendation>
+
+          <p>
+               Ensure that you use a strong, modern cryptographic hash function:
+          </p>
+
+          <ul>
+               <li>
+                    such as Argon2, scrypt, bcrypt, or PBKDF2 for passwords and other data with limited input space.
+               </li>
+               <li>
+                    such as SHA-2, or SHA-3 in other cases.
+               </li>
+          </ul>
+
+     </recommendation>
+     <example>
+
+          <p>
+               The following example shows two functions for checking whether the hash
+               of a certificate matches a known value -- to prevent tampering.
+
+               The first function uses MD5 that is known to be vulnerable to collision attacks.
+
+               The second function uses SHA-256 that is a strong cryptographic hashing function.
+          </p>
+
+          <sample src="examples/weak_certificate_hashing.py" />
+
+     </example>
+     <example>
+          <p>
+               The following example shows two functions for hashing passwords.
+
+               The first function uses SHA-256 to hash passwords. Although SHA-256 is a
+               strong cryptographic hash function, it is not suitable for password
+               hashing since it is not computationally expensive.
+          </p>
+
+          <sample src="examples/weak_password_hashing_bad.py" />
+
+
+          <p>
+               The second function uses Argon2 (through the <code>argon2-cffi</code>
+               PyPI package), which is a strong password hashing algorithm (and
+               includes a per-password salt by default).

+* Updated the _Use of a broken or weak cryptographic algorithm_ (`py/weak-cryptographic-algorithm`) query, so it alerts on any use of a weak cryptographic non-hashing algorithm. Introduced a new query _Use of a broken or weak cryptographic hashing algorithm on sensitive data_ (`py/weak-sensitive-data-hashing`) to handle weak cryptographic hashing algorithms, which only alerts when used on sensitive data.

 pointers

Smart pointer constructors, assignments, and `reset()` can actually have fairly large side effects, especially with custom deleters, destructors for objects being destroyed, and so on. I've re-introduced `{AllAliased}` side effects for these functions. There was no immediate effect on analysis results.

Subject: [PATCH 0427/1662] Python: Add non-alert data for lines of code

`py/summary/lines-of-code` is just a port of the C++/JS queries added in:

- https://github.com/github/codeql/pull/5271 (C++)
- https://github.com/github/codeql/pull/5304 (JS)

We are the first to implement the `lines-of-user-code` query, so nothing to
compare with in other languages -- but it makes a lot of sense to do for Python :+1:

This is basically just a port of the C++/JS queries added in:

- https://github.com/github/codeql/pull/5414 (C++)
- https://github.com/github/codeql/pull/5656 (JS)

SyntaxError should capture all errors we have information about. At least in
`python/ql/src/semmlecode.python.dbscheme` the only match for `error` is
`py_syntax_error_versioned` (which `SyntaxError` is based on).

+<overview>
+<p>
+JSch is a pure Java implementation of SSH2.
+JSch allows you to connect to a sshd server and use port forwarding, X11 forwarding, 
+file transfer, command execution, etc., and you can integrate its functionality into your own Java programs. 
+JSch is licensed under BSD style license.
+If an OS command is built using an attacker-controlled data, it may allow the attacker
+to run an arbitrary code on the remote host.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Including an user input in a JSch lib's OS command expression should be avoided.
+If this is not possible, then a strong input validation must be performed. 
+Some examples of an effective validation include:
+
+Validating against an allowlist of permitted values.
+Validating that the input is a number.
+Validating that the input contains only alphanumeric characters, no other syntax or whitespace.
+
+Never attempt to sanitize input by escaping shell metacharacters. In practice, 
+this is just too error-prone and vulnerable to being bypassed by a skilled attacker.
+
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example uses the untrusted data to build an OS command.
+</p>
+<sample src="JSchOSInjectionBad.java" />

Subject: [PATCH 0455/1662] Python: Use only `TApiNode` in `API::Impl`

This ensures that changes to `API::Node` does not invalidate the cached
`module Impl`. At present, I don't expect this to have any effect (as
the `Node` class is also fairly static, though not explicitly cached),
but I can imagine us making some of the `Node` methods have
user-extensible behaviour, in which case we definitely do not want this
to result in reevaluation of `API::Impl`.

Subject: [PATCH 0456/1662] Actions: Use the main branch of the codeql action

This commit switches to the bleeding edge, main branch of the
codeql action. This helps us test the action before merging all
of the new changes into main, which occurs roughly once a week.

If there are commits that introduce bugs in codeql-action, then
we will be more likely to catch it before releasing to the world
if we are using it in this extension.

-    <p>If a regular expression is built by a not escaped user-provided value, a user is likely to be able to cause a Denial of Service.</p>
-  </overview>
+<overview>
+  <p>
+    Constructing a regular expression with unsanitized user input is dangerous as a malicious user may
+    be able to modify the meaning of the expression. In particular, such a user may be able to provide
+    a regular expression fragment that takes exponential time in the worst case, and use that to
+    perform a Denial of Service attack.
+  </p>
+</overview>
 
-  <recommendation>
-    <p>In case user input must compose a regular expression, it should be escaped with functions such as <code>re.escape</code>.
-  <recommendation>
+<recommendation>
+  <p>
+    Before embedding user input into a regular expression, use a sanitization function such as
+    <code>re.escape</code> to escape meta-characters that have a special meaning regarding 
+    regular expressions' syntax.

-      Constructing a regular expression with unsanitized user input is dangerous as a malicious user may
-      be able to modify the meaning of the expression. In particular, such a user may be able to provide
-      a regular expression fragment that takes exponential time in the worst case, and use that to
-      perform a Denial of Service attack.

-      Before embedding user input into a regular expression, use a sanitization function such as

-      The following examples are based on a simple Flask web server environment.
-    </p>
-    <p>
-      The following example shows a HTTP request parameter that is used to construct a regular expression
-      without sanitizing it first:
-    </p>
-    <sample src="unit_tests/re_bad.py" />
-    <p>
-      Instead, the request parameter should be sanitized first, for example using the function
-      <code>re.escape</code>. This ensures that the user cannot insert characters which have a
-      special meaning in regular expressions.

+The following examples are based on a simple Flask web server environment.
+</p>
+<p>
+The following example shows a HTTP request parameter that is used to construct a regular expression
+without sanitizing it first:
+</p>
+<sample src="re_bad.py" />
+<p>
+Instead, the request parameter should be sanitized first, for example using the function
+<code>re.escape</code>. This ensures that the user cannot insert characters which have a
+special meaning in regular expressions.
+</p>
+<sample src="re_good.py" />
+</example>

Subject: [PATCH 0549/1662] Fix inconsistencies in information about the thief

The find-the-thief exercise is inconsistent.  The first part lists 10 answered questions about the thief, but later discussion silently adds a new question as question 8, so there are a total of 11 answered questions.

This commit updates the first list of answered questions so that it matches later discussions and the sample solution.

Subject: [PATCH 0550/1662] Python: Limit absolute imports

Limits the behaviour of github/codeql#5614 in two ways:

First, we only consider files that are contained in the source archive.
This prevents unnecessary computation involving files in e.g. the
standard library.

Secondly, we ignore any relative imports (e.g. `from .foo import ...`),
as these only work inside packages anyway.

This fixes an observed performance regression on projects that include
`google-cloud-sdk` as part of their source code.

-     * <li>Technically any RSA key of length >= 2048 bits may be used with the {@link #RS256}, {@link #RS384}, and

-     * <li>The JWT <a href="https://tools.ietf.org/html/rfc7518#section-3.1">JWA Specification (RFC 7518,

-     * recommended algorithms while the {@code PS}* variants are simply marked as optional.</li>
-     * <li>The {@link #RS256}, {@link #RS384}, and {@link #RS512} algorithms are available in the JDK by default

-/**
- * A very fast and memory efficient class to encode and decode to and from BASE64 or BASE64URL in full accordance
- * with <a href="https://tools.ietf.org/html/rfc4648">RFC 4648</a>.
- *
- * <p>Based initially on MigBase64 with continued modifications for Base64 URL support and JDK-standard code formatting.</p>
- *
- * <p>This encode/decode algorithm doesn't create any temporary arrays as many other codecs do, it only
- * allocates the resulting array. This produces less garbage and it is possible to handle arrays twice
- * as large as algorithms that create a temporary array.</p>
- *
- * <p>There is also a "fast" version of all decode methods that works the same way as the normal ones, but
- * has a few demands on the decoded input. Normally though, these fast versions should be used if the source if
- * the input is known and it hasn't bee tampered with.</p>

 <overview>
-<p>When using the <code>new</code> operator to allocate memory, you need to pay attention to the different ways of detecting errors. <code>::operator new(std::size_t)</code> throws an exception on error, whereas <code>::operator new(std::size_t, const std::nothrow_t &amp;)</code> returns zero on error. The programmer can get confused and check the error that occurs when allocating memory incorrectly. That can lead to an unhandled program termination or to a violation of the program logic.</p>
+<p>Different overloads of the <code>new</code> operator handle allocation failures in different ways:
+If <code>new T</code> fails for some type <code>T</code>, it throws a <code>std::bad_alloc</code> exception,
+but <code>new(std::nothrow) T</code> returns a null pointer. If the programmer handles the wrong kind of
+failure, it could cause the program to behave in unexpected ways.</p>
 
 </overview>
 <recommendation>
 
-<p>Use the correct error detection method corresponding with the memory allocation.</p>
+<p>Make sure that exceptions are handled appropriately if <code>new T</code> is used. On the other hand,
+make sure to handle the possibility of null pointers if <code>new(std::nothrow) T</code> is used.</p>
 
 </recommendation>
 <example>
-<p>The following example demonstrates various approaches to detecting memory allocation errors using the <code>new</code> operator.</p>
 <sample src="WrongInDetectingAndHandlingMemoryAllocationErrors.cpp" />

+<overview>
+<p>An improperly set environment variable during the creation of an RMI or JMX server can lead 
+to an unauthenticated remote code execution vulnerability. This is due to the fact that the
+RMI/JMX server environment allows attackers to supply arbitrary objects to the authentication 
+method, resulting in the attempted deserialization of an attacker-controlled object.
+</overview>
+
+<recommendation>
+<p>During the creation/initialitation of an RMI or JMX server a properly set environment (Map) variable has
+to be passed as second parameter. 
+In order to disallow the deserialization of arbitrary objects the passed environment needs to set a deserialization filter.
+Ideally this filter only allows the deserialization to <code>java.lang.String</code>.
+
+The filter can be configured by setting the key <code>jmx.remote.rmi.server.credentials.filter.pattern</code> (CONST variable <code>RMIConnectorServer.CREDENTIALS_FILTER_PATTERN</code>).
+The filter should (ideally) blacklist all classes, and only whitelist java.lang.String for deserialization: (<code> "java.lang.String;!*"</code>).
+
+The key-value pair can be set as following:
+
+<code>
+String my_filter = "java.lang.String;!*"; // Deny everything but java.lang.String
+
+Map<String, Object> env = new HashMap<String, Object>;
+env.put(RMIConnectorServer.CREDENTIALS_FILTER_PATTERN, my_filter);
+</code>
+
+For applications using &lt; Java 10:
+
+<code>
+// This is deprecated in Java 10+ !
+Map<String, Object> env = new HashMap<String, Object>;
+env.put ( 
+  "jmx.remote.rmi.server.credential.types",
+    new String[]{
+     String[].class.getName(),
+     String.class.getName()
+   }
+ );
+</code>
+
+Please note that the authentication implementation is vulnerable by default.
+For this reason an initialitation with a <code>null</code> environment is also vulnerable .
+</recommendation>
+
+<example>
+<p>The following examples show how an RMI or JMX server can be initialized securely.
+
+<p>The first example shows how an RMI server can be initialized with a secure environment.</p>
+
+<sample src="CorrectRmiInitialisation.java">

+
+<overview>
+<p>Python has been the most widely used programming language in recent years, and JPython
+  is a popular Java implementation of Python. It allows embedded Python scripting inside 
+  Java applications and provides an interactive interpreter that can be used to interact 
+  with Java packages or with running Java applications. If an expression is built using 
+  attacker-controlled data and then evaluated, it may allow the attacker to run arbitrary 
+  code.</p>
+</overview>
+
+<recommendation>
+<p>In general, including user input in JPython expression should be avoided. If user input 
+  must be included in an expression, it should be then evaluated in a safe context that 
+  doesn't allow arbitrary code invocation.</p>
+</recommendation>
+
+<example>
+<p>The following code could execute random code in JPython Interpreter</p>
+<sample src="JPythonInjection.java" />

+* Implicit base constructor calls are now extracted. For example, in
+  ```csharp
+    class Base
+    {
+        public Base() { }
+    }
+
+    class Sub : Base
+    {
+        public Sub() { }
+    }
+  ```
+  there is an implicit call to the `Base` constructor from the `Sub` constructor.

     <p>
-      Even though the request-handling methods of <code>Servlet</code> are declared <code>throws IOException, ServletException</code>, it's a bad idea to let such exceptions be thrown. Failure to catch exceptions in a servlet could leave a system in an unexpected state, possibly resulting in denial-of-service attacks, or could lead to exposure of sensitive information because when a servlet throws an exception, the servlet container typically sends debugging information back to the user. That information could be valuable to an attacker.

-<overview>
-<p>Python has been the most widely used programming language in recent years, and JPython
-  is a popular Java implementation of Python. It allows embedded Python scripting inside 
-  Java applications and provides an interactive interpreter that can be used to interact 
-  with Java packages or with running Java applications. If an expression is built using 
-  attacker-controlled data and then evaluated, it may allow the attacker to run arbitrary 
-  code.</p>
-</overview>
-
-<recommendation>
-<p>In general, including user input in JPython expression should be avoided. If user input 
-  must be included in an expression, it should be then evaluated in a safe context that 
-  doesn't allow arbitrary code invocation.</p>
-</recommendation>
-
-<example>
-<p>The following code could execute random code in JPython Interpreter</p>
-<sample src="JPythonInjection.java" />

 ## Introduction
 
 This document describes how to format the code you contribute to this repository. It covers aspects such as layout, white-space, naming, and documentation. Adhering to consistent standards makes code easier to read and maintain. Of course, these are only guidelines, and can be overridden as the need arises on a case-by-case basis. Where existing code deviates from these guidelines, prefer consistency with the surrounding code.
-Note, if you use [CodeQL for Visual Studio Code](https://help.semmle.com/codeql/codeql-for-vscode/procedures/about-codeql-for-vscode.html), you can autoformat your query in the editor.

 ### Section-level elements
 
 Section-level elements are used to group the information within the query help file. All query help files should include at least the following section elements, in the order specified:
 
-1.  `overview`—a short summary of the issue that the query identifies, including an explanation of how it could affect the behavior of the program.
-2.  `recommendation`—information on how to fix the issue highlighted by the query.
-3.  `example`—an example of code showing the problem. Where possible, this section should also include a solution to the issue.

 ## Code examples
 
 Whenever possible, you should include a code example that helps to explain the issue you are highlighting. Any code examples that you include should adhere to the following guidelines:
 
-*   The example should be less than 20 lines, but it should still clearly illustrate the issue that the query identifies.  If appropriate, then the example may also be runnable.
-*   Put the code example after the recommendation element where possible. Only include an example in the description element if absolutely necessary.
-*   If you are using an example to illustrate the solution to a problem, and the change required is minor, avoid repeating the whole example. It is preferable to either describe the change required or to include a smaller snippet of the corrected code.
-*   Clearly indicate which of the samples is an example of bad coding practice and which is recommended practice.
-*   Define the code examples in `src` files. The language is inferred from the file extension:

 You must define an `@description` property for your query. This property defines a short help message. Query descriptions should be written as a sentence or short-paragraph of plain prose, with sentence capitalization and full stop. The preferred pattern for alert queries is  "Syntax X causes behavior Y." Any code elements included in the description should be enclosed in single quotes. For example:
 
 
-*   `@description Using a format string with an incorrect format causes a 'System.FormatException'.`

+* `@description Using a format string with an incorrect format causes a 'System.FormatException'.`
+* `@description Commented-out code makes the remaining code more difficult to read.`
 
 ### Query ID `@id`
 
 You must specify an `@id` property for your query. It must be unique and should follow the standard CodeQL convention. That is, it should begin with the 'language code' for the language that the query analyzes followed by a forward slash. The following language codes are supported:
 
-*   C and C++: `cpp`
-*   C#: `cs`
-*   Go: `go`
-*   Java: `java`
-*   JavaScript and TypeScript: `js`

+* C and C++: `cpp`
+* C#: `cs`
+* Go: `go`
+* Java: `java`
+* JavaScript and TypeScript: `js`
+* Python: `py`
 
 The `@id` should consist of a short noun phrase that identifies the issue that the query highlights. For example:
 
 
 
-*   `@id cs/command-line-injection`
-*   `@id java/string-concatenation-in-loop`
+* `@id cs/command-line-injection`
+* `@id java/string-concatenation-in-loop`
 
 Further terms can be added to the `@id` to group queries that, for example, highlight similar issues or are of particular relevance to a certain framework. For example:
 
-*   `@id js/angular-js/missing-explicit-injection`
-*   `@id js/angular-js/duplicate-dependency`
+* `@id js/angular-js/missing-explicit-injection`
+* `@id js/angular-js/duplicate-dependency`
 
 Note, `@id` properties should be consistent for queries that highlight the same issue for different languages. For example, the following queries identify format strings that contain unsanitized input in Java and C++ code respectively:
 
 
 
-*   `@id java/tainted-format-string`
-*   `@id cpp/tainted-format-string`

-    *   `warning`–an issue that indicates a potential problem in the code, or makes the code fragile if another (unrelated) part of code is changed.

 ## Query tags `@tags`
 
 The `@tags` property is used to define categories that the query relates to. Each query should belong to one (or more, if necessary) of the following four top-level categories:
 
-*   `@tags correctness`–for queries that detect incorrect program behavior.
-*   `@tags maintainability`–for queries that detect patterns that make it harder for developers to make changes to the code.
-*   `@tags readability`–for queries that detect confusing patterns that make it harder for developers to read the code.
-*   `@tags security`–for queries that detect security weaknesses. See below for further information.

 If necessary, you can also define your own low-level tags to categorize the queries specific to your project or organization. When creating your own tags, you should:
 
-*   Use all lower-case letters, including for acronyms and proper nouns, with no spaces. All characters apart from * and @ are accepted.
-*   Use a forward slash / to indicate a hierarchical relationship between tags if necessary. For example, a query with tag `foo/bar` is also interpreted as also having tag `foo`, but not `bar`.
-*   Use a single-word `@tags` name. Multiple words, separated with hyphens, can be used for clarity if necessary.

-*   Where you reference another program element, link to it if possible using a substitution (`$@`). Links should be used inline in the sentence, rather than as parenthesised lists or appositions.

 The CodeQL repository also includes query suites, which can be run over your

Subject: [PATCH 0645/1662] CPP: fix semi-unused variables in
 WrongInDetectingAndHandlingMemoryAllocationErrors.ql

The fact that `aex` and `it` was each used in just one disjunct of the
exists() body caused the optimizer to generate perfectly horrible
code, including a pointless cartesian product between them that caused
the evaluation to blow up.

Fix it such that each variable is logically scoped. That makes the
compiler much happier.

+<qhelp>
+<overview>
+	<p>
+		Dynamically constructing HTML with inputs from exported functions may 
+		inadvertently leave a client open to XSS attacks.
+		
+		Clients using the exported function may use inputs containing unsafe HTML,
+		and if these inputs end up in the DOM, the client may be vulnerable to
+		cross-site scripting attacks.
+	</p>
+
+</overview>
+<recommendation>
+
+	<p>
+		If possible, use safe APIs when inserting HTML into the DOM.  
+		Such as writing to the <code>innerText</code> property instead of <code>innerHTML</code>.
+	</p>
+
+	<p>
+		Alternatively, use a HTML sanitizer to escape/remove unsafe content.
+	</p>
+
+</recommendation>
+<example>
+
+	<p>
+		The following example shows a library function that shows a boldface name
+		by writing to the <code>innerHTML</code> property of an element.
+	</p>
+
+	<sample src="examples/unsafe-html-construction.js" />
+
+	<p>
+		This library function, however, does not escape unsafe HTML, and a client
+		that calls the function with user-supplied input may be vulnerable to
+		cross-site scripting attacks.
+	</p>
+
+	<p>
+		To avoid such attacks, a program can use safe APIs such as <code>innerText</code>.
+	</p>
+
+	<sample src="examples/unsafe-html-construction_safe.js" />
+	
+	<p>
+		Alternatively, use a HTML sanitizer to remove unsafe content.

Subject: [PATCH 0710/1662] C++: Reuse SSA from earlier stages

This refactors the SSA stages of the IR so that instructions which have
a modeled memory result in the unaliased SSA stage do not have SSA
recomputed in the aliased SSA stage.

Subject: [PATCH 0758/1662] C++: Generate IR side effects for smart pointer
 indirections

When inserting side effect instructions for argument indirections, we now insert side effects for smart pointers as we would for raw pointers. The address operand of the side effect instruction is  the smart pointer object, which is a bit odd. However, I'd like to think through the design of a more principled solution before doing additional work.

A few new tests are added to the existing IR tests. In addition, the IR tests now `#include` some of the shared STL headers. I've disabled IR dumps for functions from those headers, since they only get in the way of the test cases we intended.

-<overview>
-<p>
-JSch is a pure Java implementation of SSH2.
-JSch allows you to connect to a sshd server and use port forwarding, X11 forwarding, 
-file transfer, command execution, etc., and you can integrate its functionality into your own Java programs. 
-JSch is licensed under BSD style license.
-If an OS command is built using an attacker-controlled data, it may allow the attacker
-to run an arbitrary code on the remote host.
-</p>
-</overview>
-
-<recommendation>
-<p>
-Including an user input in a JSch lib's OS command expression should be avoided.
-If this is not possible, then a strong input validation must be performed. 
-Some examples of an effective validation include:
-
-Validating against an allowlist of permitted values.
-Validating that the input is a number.
-Validating that the input contains only alphanumeric characters, no other syntax or whitespace.
-
-Never attempt to sanitize input by escaping shell metacharacters. In practice, 
-this is just too error-prone and vulnerable to being bypassed by a skilled attacker.
-
-</p>
-</recommendation>
-
-<example>
-<p>
-The following example uses the untrusted data to build an OS command.
-</p>
-<sample src="JSchOSInjectionBad.java" />
-</example>

-The following example validates the untrusted data before build an OS command.

Fixes #5828

The QLDoc was just too specific about the default implementation. I've improved the wording.

 	<p>
-		Dynamically constructing HTML with inputs from library functions that are 
-		available to external clients may inadvertently leave a client open to XSS attacks.

-		Clients using the exported function may use inputs containing unsafe HTML,
-		and if these inputs end up in the DOM, the client may be vulnerable to
-		cross-site scripting attacks.
-	</p>
+		When a library function dynamically constructs HTML in a potentially unsafe
+		way, then it's important to document to clients of the library that the function 
+		should only be used with trusted inputs. 
 
+		If the function is not documented as being potentially unsafe, then a client
+		may inadvertently use inputs containing unsafe HTML fragments, and thereby leave
+		the client vulnerable to cross-site scripting attacks.

 <recommendation>
 
 	<p>
-		If possible, use safe APIs when inserting HTML into the DOM.  
-		Such as writing to the <code>innerText</code> property instead of <code>innerHTML</code>.
+		Document all library functions that can lead to cross-site scripting 
+		attacks, and guard against unsafe inputs where dynamic HTML
+		construction is not intended.

-		Alternatively, use a HTML sanitizer to escape/remove unsafe content.

Subject: [PATCH 0784/1662] Python: Add modeling of simplejson PyPI package

I noticed that we don't handle PostUpdateNote very well in the concept tests,
for exmaple for `json.dump(...)` there _should_ have been an `encodeOutput` as
part of the inline expectations.

I'll work on fixing that up in a separate PR, to keep things clean.

Subject: [PATCH 0788/1662] Python: Add modeling of ujson PyPI package

The problem with `tainted_filelike` not having taint, is that in the call

`ujson.dump(tainted_obj, tainted_filelike)`

there is no PostUpdateNote for `tainted_filelike` :( The reason is that
points-to is not able to resolve the call, so none of the clauses in
`argumentPreUpdateNode` matches

See https://github.com/github/codeql/blob/08731fc6cf4ba6951cd4e8f239eac1f3388d3957/python/ql/src/semmle/python/dataflow/new/internal/DataFlowPrivate.qll#L101-L111

Let's deal with that issue in an other PR though

Which I had done locally. Problem is the same about not having PostUpdateNode

happy right now, and hopefully we'll get a fix to the underlying problem soon :blush:

Subject: [PATCH 0821/1662] Python: Limit set of globals that may be built-ins

I am very tempted to leave out the constants, or at the very least
`False`, `True`, and `None`, as these have _many_ occurrences in the
average codebase, and are not terribly useful at the API-graph level.

If we really do want to capture "nodes that refer to such and such
constant", then I think a better solution would be to create classes
extending `DataFlow::Node` to facilitate this.

+* The query "Resolving XML external entity in user-controlled data" (`java/xxe`) has been improved to report fewer false positives when a Builder / Factory (e.g. an `XMLInputFactory`) is configured safely by using a boxed boolean as second argument to one or more of its configuration methods.

Subject: [PATCH 0825/1662] Python: Add `exec` as a shared built-in

This is _slightly_ wrong, since `exec` isn't a built-in function in
Python 2. It should be harmless, however, since `exec` is a keyword,
and so cannot be redefined anyway.

Subject: [PATCH 0836/1662] Python: Avoid clobbering `range` in test

This was an unwanted interaction between two unrelated tests, so I
switched to a different built-in in the second test. I also added a test
case that shows an unfortunate side effect of this more restricted
handling of built-ins.

+<overview>
+<p>
+If a database query (such as a SQL or NoSQL query) is built from
+user-provided data without sufficient sanitization, a user
+may be able to run malicious database queries.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Most database connector libraries offer a way of safely
+embedding untrusted data into a query by means of query parameters
+or prepared statements.
+</p>
+</recommendation>
+
+<example>
+<p>
+In the following snippet, a user is fetched from the ClickHouse database
+using five different queries. In bad patterns query is build by formatting
+string with user-controlled data. In a qood pattern user-supplied parameter
+is send through a second argument (params) which is dict. Following cases
+show different types of communication with ClickHouse database.
+</p>
+
+<p>
+In the first case, the query executed via aioch Client. aioch - is a module
+for asynchronous queries to database.
+</p>
+
+<p>
+In the second and third cases, the connection is established via `Client` class.
+This class implement different method to execute a query.
+</p>
+
+<p>
+In the forth case, good pattern is presented. Query parameters are send through
+second dict-like argument.
+</p>
+
+<p>
+In the fifth case, there is example of PEP249 interface usage.
+</p>

+<overview>
+<p>Directly incorporating user input into a URL redirect request without validating the input
+can facilitate phishing attacks. In these attacks, unsuspecting users can be redirected to a
+malicious site that looks very similar to the real site they intend to visit, but which is
+controlled by the attacker.</p>
+
+</overview>
+<recommendation>
+
+<p>To guard against untrusted URL redirection, it is advisable to avoid putting user input
+directly into a redirect URL. Instead, maintain a list of authorized
+redirects on the server; then choose from that list based on the user input provided.</p>
+
+</recommendation>
+<example>
+
+<p>The following examples show the bad case and the good case respectively.
+In <code>bad1</code> method and <code>bad2</code> method and <code>bad3</code> method and 
+<code>bad4</code> method, shows an HTTP request parameter being used directly in a URL redirect 
+without validating the input, which facilitates phishing attacks. In <code>good1</code> method, 
+shows how to solve this problem by verifying whether the user input is a known fixed string beginning.
+</p>

Subject: [PATCH 0859/1662] Add lines-of-code tags

This is a proposed method for advertising which queries are measuring
the lines of code in a project in a more robust manner than inspecting
the rule id.

Note that the python "LinesOfUserCode" query should _not_ have this
property, as otherwise the results of the two queries will be summed.

+* The "Potential input resource leak" (`java/input-resource-leak`) and "Potential output resource leak" (`java/output-resource-leak`) queries no longer confuse `java.io` classes such as `Reader` with others that happen to share the same base name. Additionally the number of false positives has been reduced by recognizing `CharArrayReader` and `CharArrayWriter` as types that don't need to be closed.

+<overview>
+<p>
+Rhino is a JavaScript engine written fully in Java and managed by the Mozilla Foundation. 
+It serves as an embedded scripting engine inside Java applications which allows 
+Java-to-JavaScript interoperability and provides a seamless integration between the two 
+languages. If an expression is built using attacker-controlled data, and then evaluated in 
+a powerful context, it may allow the attacker to run arbitrary code.
+</p>
+<p>
+Typically an expression is evaluated in the powerful context initialized with 
+<code>initStandardObjects</code> that allows an expression of arbitrary Java code to
+execute in the JVM.
+</p>
+</overview>
+
+<recommendation>
+<p>
+In general, including user input in a Rhino expression should be avoided.
+If user input must be included in the expression, it should be then evaluated in a safe
+context that doesn't allow arbitrary code invocation.
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example shows two ways of using Rhino expression. In the 'BAD' case,
+an unsafe context is initialized with <code>initStandardObjects</code>. In the 'GOOD' case,
+a safe context is initialized with <code>initSafeStandardObjects</code> or 
+<code>setClassShutter</code>.

+ * Factory class that Rhino runtime uses to create new {@link Context}

+ * {@link #makeContext()} of the current global ContextFactory.

+ * creation. This is useful to have a set of independent Rhino runtime
+ * instances under single JVM. See {@link #call(ContextAction)}.

-<overview>
-<p>
-Rhino is a JavaScript engine written fully in Java and managed by the Mozilla Foundation. 
-It serves as an embedded scripting engine inside Java applications which allows 
-Java-to-JavaScript interoperability and provides a seamless integration between the two 
-languages. If an expression is built using attacker-controlled data, and then evaluated in 
-a powerful context, it may allow the attacker to run arbitrary code.
-</p>
-<p>
-Typically an expression is evaluated in the powerful context initialized with 
-<code>initStandardObjects</code> that allows an expression of arbitrary Java code to
-execute in the JVM.
-</p>
-</overview>
-
-<recommendation>
-<p>
-In general, including user input in a Rhino expression should be avoided.
-If user input must be included in the expression, it should be then evaluated in a safe
-context that doesn't allow arbitrary code invocation.
-</p>
-</recommendation>
-
-<example>
-<p>
-The following example shows two ways of using Rhino expression. In the 'BAD' case,
-an unsafe context is initialized with <code>initStandardObjects</code>. In the 'GOOD' case,
-a safe context is initialized with <code>initSafeStandardObjects</code> or 
-<code>setClassShutter</code>.

-<overview>
-<p>The standard library function <code>strncat(dest, source, count)</code> appends the <code>source</code> string to the <code>dest</code> string. <code>count</code> specifies the maximum number of characters to append and must be less than the remaining space in the target buffer. Calls of the form <code> strncat (dest, source, sizeof (dest) - strlen (dest)) </code> set the third argument to one more than possible. So when the <code>dest</code> is full, the expression <code> sizeof (dest) - strlen (dest) </code> will be equal to one, and not zero as the programmer might think. Making a call of this type may result in a zero byte being written just outside the <code>dest</code> buffer.</p>
-
-
-</overview>
-<recommendation>
-
-<p>We recommend subtracting one from the third argument. For example, replace <code>strncat(dest, source, sizeof(dest)-strlen(dest))</code> with <code>strncat(dest, source, sizeof(dest)-strlen(dest)-1)</code>.</p>
-
-</recommendation>
-<example>
-<p>The following example demonstrates an erroneous and corrected use of the <code>strncat</code> function.</p>

+<overview>
+<p>
+The <code>Set</code> constructor accepts an arbitrary number of arguments, but only the first one
+is used to construct the set. The remaining arguments are ignored.
+Code that invokes the <code>Set</code> constructor with multiple arguments is therefore likely to
+be incorrect.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Only pass a single argument to the <code>Set</code> constructor, which should be an iterable object
+(such as an array).
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example creates a set containing the vowels in the English language, and defines
+a function that returns a boolean indicating whether a given character is a vowel:
+</p>
+<sample src="examples/MultipleArgumentsToSetConstructorBad.js"/>
+
+<p>
+However, this code does not work as intended: the <code>Set</code> constructor ignores all but
+the first argument, so the <code>vowels</code> set only contains the letter <code>a</code>.
+</p>
+
+<p>
+Instead, the list of vowels should be wrapped into an array:
+</p>
+<sample src="examples/MultipleArgumentsToSetConstructorGood.js"/>

+<overview>
+<p>
+Java RMI uses the default Java serialization mechanism (in other words, <code>ObjectInputStream</code>)
+to pass parameters in remote method invocations. This mechanism is known to be unsafe when deserializing 
+untrusted data. If a registered remote object has a method that accepts a complex object,
+an attacker can take advantage of the unsafe deserialization mechanism.
+In the worst case, it results in remote code execution.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Use only strings and primitive types in parameters of remote objects.
+</p>
+<p>
+Java RMI does not offer API for specifying classes which are only allowed for deserialization.
+However, it is possible to set a process-wide deserialization filter that was introduced in JEP 290.
+The filter can be set via system or security property <code>jdk.serialFilter</code>.
+Make sure that you use the latest Java versions that include JEP 290.
+</p>
+<p>
+Consider using other implementations of remote procedure calls. For example, HTTP API with JSON.
+Make sure that the underlying deserialization mechanism is properly configured
+so that deserialization attacks are not possible.
+</p>
+</recommendation>
+
+<example>
+<p>
+The following code registers a vulnerable remote object 
+which has a method that accepts a complex object:
+</p>
+<sample src="RmiUnsafeRemoteObject.java" />
+
+<p>
+The next example registers a safe remote object
+which has methods that use only primitive types and strings:
+</p>
+<sample src="RmiSafeRemoteObject.java" />

-<overview>
-<p>
-If a database query (such as a SQL or NoSQL query) is built from
-user-provided data without sufficient sanitization, a user
-may be able to run malicious database queries.
-</p>
-</overview>
-
-<recommendation>
-<p>
-Most database connector libraries offer a way of safely
-embedding untrusted data into a query by means of query parameters
-or prepared statements.
-</p>
-</recommendation>
-
-<example>
-<p>
-In the following snippet, a user is fetched from a <code>ClickHouse</code> database
-using five different queries. In the "BAD" cases the query is built directly from user-controlled data.
-In the "GOOD" case the user-controlled data is safely embedded into the query by using query parameters.
-</p>
-
-<p>
-In the first case, the query executed via aioch Client. aioch - is a module
-for asynchronous queries to database.
-</p>
-
-<p>
-In the second and third cases, the connection is established via `Client` class.
-This class implement different method to execute a query.
-</p>
-
-<p>
-In the forth case, good pattern is presented. Query parameters are send through
-second dict-like argument.
-</p>
-
-<p>
-In the fifth case, there is example of PEP249 interface usage.
-</p>
-
-<p>
-In the sixth case, there is custom Class usge which is a subclass of default Client.

Subject: [PATCH 1021/1662] Python: Rewrite ClickHouse SQL lib modeling

This did turn into a few changes, that maybe could have been split into
separate PRs :shrug:

* Rename `ClickHouseDriver` => `ClickhouseDriver`, to better follow
  import name in `.qll` name
* Rewrote modeling to use API graphs
* Split modeling of `aioch` into separate `.qll` file, which does re-use
  the `getExecuteMethodName` predicate. I feel that sharing code between
  the modeling like this was the best approach, and stuck the
  `INTERNAL: Do not use.` labels on both modules.
* I also added handling of keyword arguments (see change in .py files)

 to see if the operation succeeded before operating on any data modified or resources allocated by these functions.

Subject: [PATCH 1038/1662] Python: Treat `py/summary/lines-of-user-code` as
 the primary summary metric

Move the `lines-of-code` tag from `py/summary/lines-of-code`.
Code Scanning will eventually look for this tag.

The intent is to treat the number of lines of user code for Python as the summary of
how much code was analysed, ignoring both external libraries and generated code.
This matches the current baseline metric the CodeQL Action computes for Python.
We'll revisit this decision, and the baseline, if necessary.

+Example of monotonic aggregates
+-------------------------------
+
+Consider this query:
+
+.. code-block:: ql
+
+   string getPerson() { result = "Alice" or
+                        result = "Bob" or
+                        result = "Charles" or

+                               p = "Bob"     and result = "Apple" or
+                               p = "Charles" and result = "Apple" or
+                               p = "Charles" and result = "Banana"
+                             }
+   int getPrice(string f) { f = "Apple"  and result = 100 or
+                            f = "Orange" and result = 100 or
+                            f = "Orange" and result =   1
+                          }
+
+   predicate nonmono(string p, int cost) {
+     p = getPerson() and cost = sum(string f | f = getFruit(p) | getPrice(f))
+   }
+
+   language[monotonicAggregates]
+   predicate mono(string p, int cost) {
+     p = getPerson() and cost = sum(string f | f = getFruit(p) | getPrice(f))
+   }
+
+   from string variant, string person, int cost
+   where variant = "default"  and nonmono(person, cost) or
+         variant = "monotonic" and mono(person, cost)
+   select variant, person, cost
+   order by variant, person
+
+The query produces these results:
+
++-----------+---------+------+
+|  variant  | person  | cost |
++-----------+---------+------+
+| default   | Alice   | 201  |
+| default   | Bob     | 100  |
+| default   | Charles | 100  |
+| default   | Diane   | 0    |
+| monotonic | Alice   | 101  |
+| monotonic | Alice   | 200  |
+| monotonic | Bob     | 100  |
+| monotonic | Diane   | 0    |
++-----------+---------+------+
+
+The two variants of the aggregate semantics differ in what happens
+when ``getPrice(f)`` has either multiple results or no results
+for a given ``f``.
+
+In this query, oranges are available at two different prices, and the
+default ``sum`` aggregate returns a single line where Alice buys an
+orange at a price of 100, another orange at a price of 1, and an apple
+at a price of 100, totalling 201. On the other hand, in the the
+*monotonic* semantics for ``sum``, Alice always buys one orange and
+one apple, and a line of output is produced for each *way* she can
+complete her shopping list.
+
+If there had been two different prices for apples too, the monotonic
+``sum`` would have produced *four* output lines for Alice.
+
+Charles wants to buy a banana, which is not for sale at all. In the
+default case, the sum produced for Charles includes the cost of the
+apple he *can* buy, but there's no line for Charles in the monontonic
+``sum`` output, because there *is no way* for Charles to buy one apple
+plus one banana.
+
+(Diane buys no fruit at all, and in both variants her total cost
+is 0. The ``strictsum`` aggregate would have excluded her from the
+results in both cases).
+
+In actual QL practice, it is quite rare to use monotonic aggregates
+with the *goal* of having multiple output lines, as in the "Alice"
+case of this example. The more significant point is the "Charles"
+case: As long as there's no price for bananas, no output is produced
+for him. This means that if we later do learn of a banana price, we
+don't need to *remove* any output tuple already produced. The
+importance of this is that the monotonic aggregate behavior works well
+with a fixpoint-based semantics for recursion, so it will be meaningul
+to let the ``getPrice`` predicate be mutually recursive with the count
+aggregate itself. (On the other hand, ``getFruit`` still cannot be
+allowed to be recursive, because adding another fruit to someone's
+shopping list would invalidate the total costs we already knew for
+them).
+
+This opportunity to use recursion is the main practical reason for
+requesting monotonic semantics of aggregates.

+  That means that collection and array read steps are now matched up with
+  preceding store steps. This results in increased precision for all flow-based
+  queries, in particular most of the security queries.

Subject: [PATCH 1124/1662] Python: Handle more complicated route-setup in
 aiohttp

Since we want to be able to easy select request-handlers that are not
set up as part of a view-class, we need to easily be able to identify
those. To handle cases like the one below, we _can't_ just define these
to be all the async functions that are not methods on a class :(

```py
    # see https://docs.aiohttp.org/en/stable/web_quickstart.html#organizing-handlers-in-classes

    class MyCustomHandlerClass:

        async def foo_handler(self, request):  # $ MISSING: requestHandler
            return web.Response(text="MyCustomHandlerClass.foo")

    my_custom_handler = MyCustomHandlerClass()
    app.router.add_get("/MyCustomHandlerClass/foo", my_custom_handler.foo_handler)   # $ routeSetup="/MyCustomHandlerClass/foo"
```

So it seemed easiest to narrow down the route-setups, but that means we
want both refinement and extensibility... so `::Range` pattern to the
rescue :tada:

The important piece of code that still works after this commit, but
which hasn't been changed, is the one below:

```codeql
  /**
   * A parameter that will receive a `aiohttp.web.Request` instance when a request
   * handler is invoked.
   */
  class AiohttpRequestHandlerRequestParam extends Request::InstanceSource, RemoteFlowSource::Range,
    DataFlow::ParameterNode {
    AiohttpRequestHandlerRequestParam() {
      exists(Function requestHandler |
        requestHandler = any(AiohttpCoroutineRouteSetup setup).getARequestHandler() and
```

-Notes for legacy QL CLI users
-=============================
-
-If you've previously used the QL command-line tools (``odasa``), you'll notice a
-few key differences when you use the new CodeQL products:
-
-* "QL snapshots" are now called `CodeQL databases <https://help.semmle.com/codeql/glossary.html#codeql-database>`__. 
-* The process of creating a CodeQL database is much simpler and more streamlined.
-  There's no need to create ``projects`` or ``snapshots``---just check out the
-  code and build it using the CodeQL CLI ``codeql database create`` command.
-* Queries are run against CodeQL databases using the CodeQL CLI ``codeql
-  database analyze`` command.
-
-For more information, see `Creating CodeQL databases
-<https://help.semmle.com/codeql/codeql-cli/procedures/create-codeql-database.html>`__ and 
-`Analyzing databases with the CodeQL CLI <https://help.semmle.com/codeql/codeql-cli/procedures/analyze-codeql-database.html>`__.
-For detailed guidance about equivalent commands, see `Overview of common commands
-<#overview-of-common-commands>`__ below.

-
-Database compatibility notes
-----------------------------
-
-A CodeQL database created by the CodeQL CLI serves the same purpose as a QL
-snapshot created using ``odasa``. They both contain a code database to query and
-usually a source reference for results display. However, they are not identical
-formats and, if you use the legacy QL tools alongside the CodeQL tools, you need
-to be aware of the following:
-
-* Existing QL snapshots, exported using the legacy CLI, can be used with the new
-  CodeQL tools. Unzip the snapshot and treat the directory as a database. If it
-  was built with an earlier version of the legacy CLI, you may need to upgrade
-  the database using ``codeql database upgrade``. For more information, see the
-  `database upgrade reference documentation
-  <https://help.semmle.com/codeql/codeql-cli/commands/database-upgrade.html>`__.
-
-* CodeQL databases are not directly compatible with CodeQL for Eclipse.
-  However, you can "bundle" a CodeQL database into the equivalent of a QL
-  exported snapshot by running::
-
-    codeql database bundle --include-uncompressed-source -o <output-zip> <codeql-database>
-  
-  The resulting database can be imported into CodeQL for Eclipse. For more
-  information, see the `database bundle reference documentation <https://help.semmle.com/codeql/codeql-cli/commands/database-bundle.html>`__.
-
-* .. include:: ../reusables/index-files-note.rst
-
-* CodeQL databases cannot be directly uploaded to an LGTM Enterprise instance.
-  For more information, see `Preparing CodeQL databases to upload to LGTM 
-  <https://help.semmle.com/lgtm-enterprise/admin/help/prepare-database-upload.html>`__
-  in the LGTM admin help.
-
-Query suites
-------------
-
-CodeQL includes a new, more flexible, format for query suites. Legacy query
-suite definitions are not compatible with the new CodeQL tools. For more
-information about CodeQL query suites, see `Creating CodeQL query suites
-<https://help.semmle.com/codeql/codeql-cli/procedures/query-suites.html>`__. 
-
-Overview of common commands 
----------------------------
-
-If you're switching from the legacy ODASA CLI to the new CodeQL CLI, 
-the table below shows which commands replace the most
-common ODASA processes.

Subject: [PATCH 1177/1662] Replace an odd `queries.xml` with `qlpack.yml`

This one C++ test has its own `queries.xml` to make "outside-of-source" path filtering work, as detailed in commit 2550788598010fa2117274607c9d58f64f997f34. I've replaced the `queries.xml` with `qlpack.yml`, added a comment, and added that pack to the `.codeqlmanifest.json` at the root of the repo. This will allow the library dependencies of this pack to be resolved without the need for a `--search-path` option with the upcoming packaging changes.

+      or previous Modifications;
+
+      B. Any new file that contains any part of the Original Software or
+      previous Modification; or
+
+      C. Any new file that is contributed or otherwise made available
+      under the terms of this License.
+
+      1.10. "Original Software" means the Source Code and Executable form
+      of computer software code that is originally released under this
+      License.
+
+      1.11. "Patent Claims" means any patent claim(s), now owned or
+      hereafter acquired, including without limitation, method, process,
+      and apparatus claims, in any patent Licensable by grantor.
+
+      1.12. "Source Code" means (a) the common form of computer software
+      code in which modifications are made and (b) associated
+      documentation included in or with such code.
+
+      1.13. "You" (or "Your") means an individual or a legal entity
+      exercising rights under, and complying with all of the terms of,
+      this License. For legal entities, "You" includes any entity which
+      controls, is controlled by, or is under common control with You. For
+      purposes of this definition, "control" means (a) the power, direct
+      or indirect, to cause the direction or management of such entity,
+      whether by contract or otherwise, or (b) ownership of more than
+      fifty percent (50%) of the outstanding shares or beneficial
+      ownership of such entity.
+
+    2. License Grants.
+
+      2.1. The Initial Developer Grant.
+
+      Conditioned upon Your compliance with Section 3.1 below and subject
+      to third party intellectual property claims, the Initial Developer
+      hereby grants You a world-wide, royalty-free, non-exclusive license:
+
+      (a) under intellectual property rights (other than patent or
+      trademark) Licensable by Initial Developer, to use, reproduce,
+      modify, display, perform, sublicense and distribute the Original
+      Software (or portions thereof), with or without Modifications,
+      and/or as part of a Larger Work; and
+
+      (b) under Patent Claims infringed by the making, using or selling of
+      Original Software, to make, have made, use, practice, sell, and
+      offer for sale, and/or otherwise dispose of the Original Software
+      (or portions thereof).
+
+      (c) The licenses granted in Sections 2.1(a) and (b) are effective on
+      the date Initial Developer first distributes or otherwise makes the
+      Original Software available to a third party under the terms of this
+      License.
+
+      (d) Notwithstanding Section 2.1(b) above, no patent license is
+      granted: (1) for code that You delete from the Original Software, or
+      (2) for infringements caused by: (i) the modification of the
+      Original Software, or (ii) the combination of the Original Software
+      with other software or devices.
+
+      2.2. Contributor Grant.
+
+      Conditioned upon Your compliance with Section 3.1 below and subject
+      to third party intellectual property claims, each Contributor hereby
+      grants You a world-wide, royalty-free, non-exclusive license:
+
+      (a) under intellectual property rights (other than patent or
+      trademark) Licensable by Contributor to use, reproduce, modify,
+      display, perform, sublicense and distribute the Modifications
+      created by such Contributor (or portions thereof), either on an
+      unmodified basis, with other Modifications, as Covered Software
+      and/or as part of a Larger Work; and
+
+      (b) under Patent Claims infringed by the making, using, or selling
+      of Modifications made by that Contributor either alone and/or in
+      combination with its Contributor Version (or portions of such
+      combination), to make, use, sell, offer for sale, have made, and/or
+      otherwise dispose of: (1) Modifications made by that Contributor (or
+      portions thereof); and (2) the combination of Modifications made by
+      that Contributor with its Contributor Version (or portions of such
+      combination).
+
+      (c) The licenses granted in Sections 2.2(a) and 2.2(b) are effective
+      on the date Contributor first distributes or otherwise makes the
+      Modifications available to a third party.
+
+      (d) Notwithstanding Section 2.2(b) above, no patent license is
+      granted: (1) for any code that Contributor has deleted from the
+      Contributor Version; (2) for infringements caused by: (i) third
+      party modifications of Contributor Version, or (ii) the combination
+      of Modifications made by that Contributor with other software
+      (except as part of the Contributor Version) or other devices; or (3)
+      under Patent Claims infringed by Covered Software in the absence of
+      Modifications made by that Contributor.
+
+    3. Distribution Obligations.
+
+      3.1. Availability of Source Code.
+
+      Any Covered Software that You distribute or otherwise make available
+      in Executable form must also be made available in Source Code form
+      and that Source Code form must be distributed only under the terms
+      of this License. You must include a copy of this License with every
+      copy of the Source Code form of the Covered Software You distribute
+      or otherwise make available. You must inform recipients of any such
+      Covered Software in Executable form as to how they can obtain such
+      Covered Software in Source Code form in a reasonable manner on or
+      through a medium customarily used for software exchange.
+
+      3.2. Modifications.
+
+      The Modifications that You create or to which You contribute are
+      governed by the terms of this License. You represent that You
+      believe Your Modifications are Your original creation(s) and/or You
+      have sufficient rights to grant the rights conveyed by this License.
+
+      3.3. Required Notices.
+
+      You must include a notice in each of Your Modifications that
+      identifies You as the Contributor of the Modification. You may not
+      remove or alter any copyright, patent or trademark notices contained
+      within the Covered Software, or any notices of licensing or any
+      descriptive text giving attribution to any Contributor or the
+      Initial Developer.
+
+      3.4. Application of Additional Terms.
+
+      You may not offer or impose any terms on any Covered Software in
+      Source Code form that alters or restricts the applicable version of
+      this License or the recipients' rights hereunder. You may choose to
+      offer, and to charge a fee for, warranty, support, indemnity or
+      liability obligations to one or more recipients of Covered Software.
+      However, you may do so only on Your own behalf, and not on behalf of
+      the Initial Developer or any Contributor. You must make it
+      absolutely clear that any such warranty, support, indemnity or
+      liability obligation is offered by You alone, and You hereby agree
+      to indemnify the Initial Developer and every Contributor for any
+      liability incurred by the Initial Developer or such Contributor as a
+      result of warranty, support, indemnity or liability terms You offer.
+
+      3.5. Distribution of Executable Versions.
+
+      You may distribute the Executable form of the Covered Software under
+      the terms of this License or under the terms of a license of Your
+      choice, which may contain terms different from this License,
+      provided that You are in compliance with the terms of this License
+      and that the license for the Executable form does not attempt to
+      limit or alter the recipient's rights in the Source Code form from
+      the rights set forth in this License. If You distribute the Covered
+      Software in Executable form under a different license, You must make
+      it absolutely clear that any terms which differ from this License
+      are offered by You alone, not by the Initial Developer or
+      Contributor. You hereby agree to indemnify the Initial Developer and
+      every Contributor for any liability incurred by the Initial
+      Developer or such Contributor as a result of any such terms You offer.
+
+      3.6. Larger Works.
+
+      You may create a Larger Work by combining Covered Software with
+      other code not governed by the terms of this License and distribute
+      the Larger Work as a single product. In such a case, You must make
+      sure the requirements of this License are fulfilled for the Covered
+      Software.
+
+    4. Versions of the License.
+
+      4.1. New Versions.
+
+      Oracle is the initial license steward and may publish revised and/or
+      new versions of this License from time to time. Each version will be
+      given a distinguishing version number. Except as provided in Section
+      4.3, no one other than the license steward has the right to modify
+      this License.
+
+      4.2. Effect of New Versions.
+
+      You may always continue to use, distribute or otherwise make the
+      Covered Software available under the terms of the version of the
+      License under which You originally received the Covered Software. If
+      the Initial Developer includes a notice in the Original Software
+      prohibiting it from being distributed or otherwise made available
+      under any subsequent version of the License, You must distribute and
+      make the Covered Software available under the terms of the version
+      of the License under which You originally received the Covered
+      Software. Otherwise, You may also choose to use, distribute or
+      otherwise make the Covered Software available under the terms of any
+      subsequent version of the License published by the license steward.
+
+      4.3. Modified Versions.
+
+      When You are an Initial Developer and You want to create a new
+      license for Your Original Software, You may create and use a
+      modified version of this License if You: (a) rename the license and
+      remove any references to the name of the license steward (except to
+      note that the license differs from this License); and (b) otherwise
+      make it clear that the license contains terms which differ from this
+      License.
+
+    5. DISCLAIMER OF WARRANTY.
+
+      COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+      WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+      INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED SOFTWARE
+      IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR
+      NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF
+      THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY COVERED SOFTWARE PROVE
+      DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY
+      OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING,
+      REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
+      ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED SOFTWARE IS
+      AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+    6. TERMINATION.
+
+      6.1. This License and the rights granted hereunder will terminate
+      automatically if You fail to comply with terms herein and fail to
+      cure such breach within 30 days of becoming aware of the breach.
+      Provisions which, by their nature, must remain in effect beyond the
+      termination of this License shall survive.
+
+      6.2. If You assert a patent infringement claim (excluding
+      declaratory judgment actions) against Initial Developer or a
+      Contributor (the Initial Developer or Contributor against whom You
+      assert such claim is referred to as "Participant") alleging that the
+      Participant Software (meaning the Contributor Version where the
+      Participant is a Contributor or the Original Software where the
+      Participant is the Initial Developer) directly or indirectly
+      infringes any patent, then any and all rights granted directly or
+      indirectly to You by such Participant, the Initial Developer (if the
+      Initial Developer is not the Participant) and all Contributors under
+      Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice
+      from Participant terminate prospectively and automatically at the
+      expiration of such 60 day notice period, unless if within such 60
+      day period You withdraw Your claim with respect to the Participant
+      Software against such Participant either unilaterally or pursuant to
+      a written agreement with Participant.
+
+      6.3. If You assert a patent infringement claim against Participant
+      alleging that the Participant Software directly or indirectly
+      infringes any patent where such claim is resolved (such as by
+      license or settlement) prior to the initiation of patent
+      infringement litigation, then the reasonable value of the licenses
+      granted by such Participant under Sections 2.1 or 2.2 shall be taken
+      into account in determining the amount or value of any payment or
+      license.
+
+      6.4. In the event of termination under Sections 6.1 or 6.2 above,
+      all end user licenses that have been validly granted by You or any
+      distributor hereunder prior to termination (excluding licenses
+      granted to You by any distributor) shall survive termination.
+
+    7. LIMITATION OF LIABILITY.
+
+      UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+      (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
+      INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
+      COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE
+      TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
+      CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
+      LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
+      FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR
+      LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE
+      POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT
+      APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH
+      PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH
+      LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
+      LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION
+      AND LIMITATION MAY NOT APPLY TO YOU.
+
+    8. U.S. GOVERNMENT END USERS.
+
+      The Covered Software is a "commercial item," as that term is defined
+      in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+      software" (as that term is defined at 48 C.F.R. §
+      252.227-7014(a)(1)) and "commercial computer software documentation"
+      as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent
+      with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
+      (June 1995), all U.S. Government End Users acquire Covered Software
+      with only those rights set forth herein. This U.S. Government Rights
+      clause is in lieu of, and supersedes, any other FAR, DFAR, or other
+      clause or provision that addresses Government rights in computer
+      software under this License.
+
+    9. MISCELLANEOUS.
+
+      This License represents the complete agreement concerning subject
+      matter hereof. If any provision of this License is held to be
+      unenforceable, such provision shall be reformed only to the extent
+      necessary to make it enforceable. This License shall be governed by
+      the law of the jurisdiction specified in a notice contained within
+      the Original Software (except to the extent applicable law, if any,
+      provides otherwise), excluding such jurisdiction's conflict-of-law
+      provisions. Any litigation relating to this License shall be subject
+      to the jurisdiction of the courts located in the jurisdiction and
+      venue specified in a notice contained within the Original Software,
+      with the losing party responsible for costs, including, without
+      limitation, court costs and reasonable attorneys' fees and expenses.
+      The application of the United Nations Convention on Contracts for
+      the International Sale of Goods is expressly excluded. Any law or
+      regulation which provides that the language of a contract shall be
+      construed against the drafter shall not apply to this License. You
+      agree that You alone are responsible for compliance with the United
+      States export administration regulations (and the export control
+      laws and regulation of any other countries) when You use, distribute
+      or otherwise make available any Covered Software.
+
+    10. RESPONSIBILITY FOR CLAIMS.
+
+      As between Initial Developer and the Contributors, each party is
+      responsible for claims and damages arising, directly or indirectly,
+      out of its utilization of rights under this License and You agree to
+      work with Initial Developer and Contributors to distribute such
+      responsibility on an equitable basis. Nothing herein is intended or
+      shall be deemed to constitute any admission of liability.
+

+##    NOTICE PURSUANT TO SECTION 9 OF THE COMMON DEVELOPMENT AND DISTRIBUTION LICENSE (CDDL)
+
+    The code released under the CDDL shall be governed by the laws of the
+    State of California (excluding conflict-of-law provisions). Any
+    litigation relating to this License shall be subject to the jurisdiction

+    state courts of the State of California, with venue lying in Santa Clara
+    County, California.

+
+    Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+    51 Franklin Street, Fifth Floor
+    Boston, MA 02110-1335
+    USA
+
+    Everyone is permitted to copy and distribute verbatim copies
+    of this license document, but changing it is not allowed.
+
+    Preamble
+
+    The licenses for most software are designed to take away your freedom to
+    share and change it. By contrast, the GNU General Public License is
+    intended to guarantee your freedom to share and change free software--to
+    make sure the software is free for all its users. This General Public
+    License applies to most of the Free Software Foundation's software and
+    to any other program whose authors commit to using it. (Some other Free
+    Software Foundation software is covered by the GNU Library General
+    Public License instead.) You can apply it to your programs, too.
+
+    When we speak of free software, we are referring to freedom, not price.
+    Our General Public Licenses are designed to make sure that you have the
+    freedom to distribute copies of free software (and charge for this
+    service if you wish), that you receive source code or can get it if you
+    want it, that you can change the software or use pieces of it in new
+    free programs; and that you know you can do these things.
+
+    To protect your rights, we need to make restrictions that forbid anyone
+    to deny you these rights or to ask you to surrender the rights. These
+    restrictions translate to certain responsibilities for you if you
+    distribute copies of the software, or if you modify it.
+
+    For example, if you distribute copies of such a program, whether gratis
+    or for a fee, you must give the recipients all the rights that you have.
+    You must make sure that they, too, receive or can get the source code.
+    And you must show them these terms so they know their rights.
+
+    We protect your rights with two steps: (1) copyright the software, and
+    (2) offer you this license which gives you legal permission to copy,
+    distribute and/or modify the software.
+
+    Also, for each author's protection and ours, we want to make certain
+    that everyone understands that there is no warranty for this free
+    software. If the software is modified by someone else and passed on, we
+    want its recipients to know that what they have is not the original, so
+    that any problems introduced by others will not reflect on the original
+    authors' reputations.
+
+    Finally, any free program is threatened constantly by software patents.
+    We wish to avoid the danger that redistributors of a free program will
+    individually obtain patent licenses, in effect making the program
+    proprietary. To prevent this, we have made it clear that any patent must
+    be licensed for everyone's free use or not licensed at all.
+
+    The precise terms and conditions for copying, distribution and
+    modification follow.
+
+    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+    0. This License applies to any program or other work which contains a
+    notice placed by the copyright holder saying it may be distributed under
+    the terms of this General Public License. The "Program", below, refers
+    to any such program or work, and a "work based on the Program" means
+    either the Program or any derivative work under copyright law: that is
+    to say, a work containing the Program or a portion of it, either
+    verbatim or with modifications and/or translated into another language.
+    (Hereinafter, translation is included without limitation in the term
+    "modification".) Each licensee is addressed as "you".
+
+    Activities other than copying, distribution and modification are not
+    covered by this License; they are outside its scope. The act of running
+    the Program is not restricted, and the output from the Program is
+    covered only if its contents constitute a work based on the Program
+    (independent of having been made by running the Program). Whether that
+    is true depends on what the Program does.
+
+    1. You may copy and distribute verbatim copies of the Program's source
+    code as you receive it, in any medium, provided that you conspicuously
+    and appropriately publish on each copy an appropriate copyright notice
+    and disclaimer of warranty; keep intact all the notices that refer to
+    this License and to the absence of any warranty; and give any other
+    recipients of the Program a copy of this License along with the Program.
+
+    You may charge a fee for the physical act of transferring a copy, and
+    you may at your option offer warranty protection in exchange for a fee.
+
+    2. You may modify your copy or copies of the Program or any portion of
+    it, thus forming a work based on the Program, and copy and distribute
+    such modifications or work under the terms of Section 1 above, provided
+    that you also meet all of these conditions:
+
+        a) You must cause the modified files to carry prominent notices
+        stating that you changed the files and the date of any change.
+
+        b) You must cause any work that you distribute or publish, that in
+        whole or in part contains or is derived from the Program or any part
+        thereof, to be licensed as a whole at no charge to all third parties
+        under the terms of this License.
+
+        c) If the modified program normally reads commands interactively
+        when run, you must cause it, when started running for such
+        interactive use in the most ordinary way, to print or display an
+        announcement including an appropriate copyright notice and a notice
+        that there is no warranty (or else, saying that you provide a
+        warranty) and that users may redistribute the program under these
+        conditions, and telling the user how to view a copy of this License.
+        (Exception: if the Program itself is interactive but does not
+        normally print such an announcement, your work based on the Program
+        is not required to print an announcement.)
+
+    These requirements apply to the modified work as a whole. If
+    identifiable sections of that work are not derived from the Program, and
+    can be reasonably considered independent and separate works in
+    themselves, then this License, and its terms, do not apply to those
+    sections when you distribute them as separate works. But when you
+    distribute the same sections as part of a whole which is a work based on
+    the Program, the distribution of the whole must be on the terms of this
+    License, whose permissions for other licensees extend to the entire
+    whole, and thus to each and every part regardless of who wrote it.
+
+    Thus, it is not the intent of this section to claim rights or contest
+    your rights to work written entirely by you; rather, the intent is to
+    exercise the right to control the distribution of derivative or
+    collective works based on the Program.
+
+    In addition, mere aggregation of another work not based on the Program
+    with the Program (or with a work based on the Program) on a volume of a
+    storage or distribution medium does not bring the other work under the
+    scope of this License.
+
+    3. You may copy and distribute the Program (or a work based on it,
+    under Section 2) in object code or executable form under the terms of
+    Sections 1 and 2 above provided that you also do one of the following:
+
+        a) Accompany it with the complete corresponding machine-readable
+        source code, which must be distributed under the terms of Sections 1
+        and 2 above on a medium customarily used for software interchange; or,
+
+        b) Accompany it with a written offer, valid for at least three
+        years, to give any third party, for a charge no more than your cost
+        of physically performing source distribution, a complete
+        machine-readable copy of the corresponding source code, to be
+        distributed under the terms of Sections 1 and 2 above on a medium
+        customarily used for software interchange; or,
+
+        c) Accompany it with the information you received as to the offer to
+        distribute corresponding source code. (This alternative is allowed
+        only for noncommercial distribution and only if you received the
+        program in object code or executable form with such an offer, in
+        accord with Subsection b above.)
+
+    The source code for a work means the preferred form of the work for
+    making modifications to it. For an executable work, complete source code
+    means all the source code for all modules it contains, plus any
+    associated interface definition files, plus the scripts used to control
+    compilation and installation of the executable. However, as a special
+    exception, the source code distributed need not include anything that is
+    normally distributed (in either source or binary form) with the major
+    components (compiler, kernel, and so on) of the operating system on
+    which the executable runs, unless that component itself accompanies the
+    executable.
+
+    If distribution of executable or object code is made by offering access
+    to copy from a designated place, then offering equivalent access to copy
+    the source code from the same place counts as distribution of the source
+    code, even though third parties are not compelled to copy the source
+    along with the object code.
+
+    4. You may not copy, modify, sublicense, or distribute the Program
+    except as expressly provided under this License. Any attempt otherwise
+    to copy, modify, sublicense or distribute the Program is void, and will
+    automatically terminate your rights under this License. However, parties
+    who have received copies, or rights, from you under this License will
+    not have their licenses terminated so long as such parties remain in
+    full compliance.
+
+    5. You are not required to accept this License, since you have not
+    signed it. However, nothing else grants you permission to modify or
+    distribute the Program or its derivative works. These actions are
+    prohibited by law if you do not accept this License. Therefore, by
+    modifying or distributing the Program (or any work based on the
+    Program), you indicate your acceptance of this License to do so, and all
+    its terms and conditions for copying, distributing or modifying the
+    Program or works based on it.
+
+    6. Each time you redistribute the Program (or any work based on the
+    Program), the recipient automatically receives a license from the
+    original licensor to copy, distribute or modify the Program subject to
+    these terms and conditions. You may not impose any further restrictions
+    on the recipients' exercise of the rights granted herein. You are not
+    responsible for enforcing compliance by third parties to this License.
+
+    7. If, as a consequence of a court judgment or allegation of patent
+    infringement or for any other reason (not limited to patent issues),
+    conditions are imposed on you (whether by court order, agreement or
+    otherwise) that contradict the conditions of this License, they do not
+    excuse you from the conditions of this License. If you cannot distribute
+    so as to satisfy simultaneously your obligations under this License and
+    any other pertinent obligations, then as a consequence you may not
+    distribute the Program at all. For example, if a patent license would
+    not permit royalty-free redistribution of the Program by all those who
+    receive copies directly or indirectly through you, then the only way you
+    could satisfy both it and this License would be to refrain entirely from
+    distribution of the Program.
+
+    If any portion of this section is held invalid or unenforceable under
+    any particular circumstance, the balance of the section is intended to
+    apply and the section as a whole is intended to apply in other
+    circumstances.
+
+    It is not the purpose of this section to induce you to infringe any
+    patents or other property right claims or to contest validity of any
+    such claims; this section has the sole purpose of protecting the
+    integrity of the free software distribution system, which is implemented
+    by public license practices. Many people have made generous
+    contributions to the wide range of software distributed through that
+    system in reliance on consistent application of that system; it is up to
+    the author/donor to decide if he or she is willing to distribute
+    software through any other system and a licensee cannot impose that choice.
+
+    This section is intended to make thoroughly clear what is believed to be
+    a consequence of the rest of this License.
+
+    8. If the distribution and/or use of the Program is restricted in
+    certain countries either by patents or by copyrighted interfaces, the
+    original copyright holder who places the Program under this License may
+    add an explicit geographical distribution limitation excluding those
+    countries, so that distribution is permitted only in or among countries
+    not thus excluded. In such case, this License incorporates the
+    limitation as if written in the body of this License.
+
+    9. The Free Software Foundation may publish revised and/or new
+    versions of the General Public License from time to time. Such new
+    versions will be similar in spirit to the present version, but may
+    differ in detail to address new problems or concerns.
+
+    Each version is given a distinguishing version number. If the Program
+    specifies a version number of this License which applies to it and "any
+    later version", you have the option of following the terms and
+    conditions either of that version or of any later version published by
+    the Free Software Foundation. If the Program does not specify a version
+    number of this License, you may choose any version ever published by the
+    Free Software Foundation.
+
+    10. If you wish to incorporate parts of the Program into other free
+    programs whose distribution conditions are different, write to the
+    author to ask for permission. For software which is copyrighted by the
+    Free Software Foundation, write to the Free Software Foundation; we
+    sometimes make exceptions for this. Our decision will be guided by the
+    two goals of preserving the free status of all derivatives of our free
+    software and of promoting the sharing and reuse of software generally.
+
+    NO WARRANTY
+
+    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
+    WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+    EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+    OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND,
+    EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+    WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+    ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
+    YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+    NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+    WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+    AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+    DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+    DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+    (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+    INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+    THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR
+    OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+    END OF TERMS AND CONDITIONS
+
+    How to Apply These Terms to Your New Programs
+
+    If you develop a new program, and you want it to be of the greatest
+    possible use to the public, the best way to achieve this is to make it
+    free software which everyone can redistribute and change under these terms.
+
+    To do so, attach the following notices to the program. It is safest to
+    attach them to the start of each source file to most effectively convey
+    the exclusion of warranty; and each file should have at least the
+    "copyright" line and a pointer to where the full notice is found.
+
+        One line to give the program's name and a brief idea of what it does.
+        Copyright (C) <year> <name of author>
+
+        This program is free software; you can redistribute it and/or modify
+        it under the terms of the GNU General Public License as published by
+        the Free Software Foundation; either version 2 of the License, or
+        (at your option) any later version.
+
+        This program is distributed in the hope that it will be useful, but
+        WITHOUT ANY WARRANTY; without even the implied warranty of
+        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+        General Public License for more details.
+
+        You should have received a copy of the GNU General Public License
+        along with this program; if not, write to the Free Software
+        Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1335 USA
+
+    Also add information on how to contact you by electronic and paper mail.
+
+    If the program is interactive, make it output a short notice like this
+    when it starts in an interactive mode:
+
+        Gnomovision version 69, Copyright (C) year name of author
+        Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type
+        `show w'. This is free software, and you are welcome to redistribute
+        it under certain conditions; type `show c' for details.
+
+    The hypothetical commands `show w' and `show c' should show the
+    appropriate parts of the General Public License. Of course, the commands
+    you use may be called something other than `show w' and `show c'; they
+    could even be mouse-clicks or menu items--whatever suits your program.
+
+    You should also get your employer (if you work as a programmer) or your
+    school, if any, to sign a "copyright disclaimer" for the program, if
+    necessary. Here is a sample; alter the names:
+
+        Yoyodyne, Inc., hereby disclaims all copyright interest in the
+        program `Gnomovision' (which makes passes at compilers) written by
+        James Hacker.
+
+        signature of Ty Coon, 1 April 1989
+        Ty Coon, President of Vice
+
+    This General Public License does not permit incorporating your program
+    into proprietary programs. If your program is a subroutine library, you
+    may consider it more useful to permit linking proprietary applications
+    with the library. If this is what you want to do, use the GNU Library
+    General Public License instead of this License.
+
+---
+
+    Certain source files distributed by Oracle America, Inc. and/or its
+    affiliates are subject to the following clarification and special
+    exception to the GPLv2, based on the GNU Project exception for its
+    Classpath libraries, known as the GNU Classpath Exception, but only
+    where Oracle has expressly included in the particular source file's
+    header the words "Oracle designates this particular file as subject to
+    the "Classpath" exception as provided by Oracle in the LICENSE file
+    that accompanied this code."
+
+    You should also note that Oracle includes multiple, independent
+    programs in this software package. Some of those programs are provided
+    under licenses deemed incompatible with the GPLv2 by the Free Software
+    Foundation and others.  For example, the package includes programs
+    licensed under the Apache License, Version 2.0.  Such programs are
+    licensed to you under their original licenses.
+
+    Oracle facilitates your further distribution of this package by adding
+    the Classpath Exception to the necessary parts of its GPLv2 code, which
+    permits you to use that code in combination with other independent
+    modules not licensed under the GPLv2.  However, note that this would
+    not permit you to commingle code under an incompatible license with
+    Oracle's GPLv2 licensed code by, for example, cutting and pasting such
+    code into a file also containing Oracle's GPLv2 licensed code and then
+    distributing the result.  Additionally, if you were to remove the
+    Classpath Exception from any of the files to which it applies and
+    distribute the result, you would likely be required to license some or
+    all of the other code in that distribution under the GPLv2 as well, and
+    since the GPLv2 is incompatible with the license terms of some items
+    included in the distribution by Oracle, removing the Classpath
+    Exception could therefore effectively compromise your ability to
+    further distribute the package.
+
+    Proceed with caution and we recommend that you obtain the advice of a
+    lawyer skilled in open source matters before removing the Classpath
+    Exception or making modifications to this package which may
+    subsequently be redistributed and/or involve the use of third party
+    software.
+
+    CLASSPATH EXCEPTION
+    Linking this library statically or dynamically with other modules is
+    making a combined work based on this library.  Thus, the terms and
+    conditions of the GNU General Public License version 2 cover the whole
+    combination.
+
+    As a special exception, the copyright holders of this library give you
+    permission to link this library with independent modules to produce an
+    executable, regardless of the license terms of these independent
+    modules, and to copy and distribute the resulting executable under
+    terms of your choice, provided that you also meet, for each linked
+    independent module, the terms and conditions of the license of that
+    module.  An independent module is a module which is not derived from or
+    based on this library.  If you modify this library, you may extend this
+    exception to your version of the library, but you are not obligated to
+    do so.  If you do not wish to do so, delete this exception statement
+    from your version.

+    controls, is controlled by, or is under common control with You. For
+    purposes of this definition, "control" means (a) the power, direct
+    or indirect, to cause the direction or management of such entity,
+    whether by contract or otherwise, or (b) ownership of more than
+    fifty percent (50%) of the outstanding shares or beneficial
+    ownership of such entity.
+
+2. License Grants.
+
+    2.1. The Initial Developer Grant.
+
+    Conditioned upon Your compliance with Section 3.1 below and subject
+    to third party intellectual property claims, the Initial Developer
+    hereby grants You a world-wide, royalty-free, non-exclusive license:
+
+    (a) under intellectual property rights (other than patent or
+    trademark) Licensable by Initial Developer, to use, reproduce,
+    modify, display, perform, sublicense and distribute the Original
+    Software (or portions thereof), with or without Modifications,
+    and/or as part of a Larger Work; and
+
+    (b) under Patent Claims infringed by the making, using or selling of
+    Original Software, to make, have made, use, practice, sell, and
+    offer for sale, and/or otherwise dispose of the Original Software
+    (or portions thereof).
+
+    (c) The licenses granted in Sections 2.1(a) and (b) are effective on
+    the date Initial Developer first distributes or otherwise makes the
+    Original Software available to a third party under the terms of this
+    License.
+
+    (d) Notwithstanding Section 2.1(b) above, no patent license is
+    granted: (1) for code that You delete from the Original Software, or
+    (2) for infringements caused by: (i) the modification of the
+    Original Software, or (ii) the combination of the Original Software
+    with other software or devices.
+
+    2.2. Contributor Grant.
+
+    Conditioned upon Your compliance with Section 3.1 below and subject
+    to third party intellectual property claims, each Contributor hereby
+    grants You a world-wide, royalty-free, non-exclusive license:
+
+    (a) under intellectual property rights (other than patent or
+    trademark) Licensable by Contributor to use, reproduce, modify,
+    display, perform, sublicense and distribute the Modifications
+    created by such Contributor (or portions thereof), either on an
+    unmodified basis, with other Modifications, as Covered Software
+    and/or as part of a Larger Work; and
+
+    (b) under Patent Claims infringed by the making, using, or selling
+    of Modifications made by that Contributor either alone and/or in
+    combination with its Contributor Version (or portions of such
+    combination), to make, use, sell, offer for sale, have made, and/or
+    otherwise dispose of: (1) Modifications made by that Contributor (or
+    portions thereof); and (2) the combination of Modifications made by
+    that Contributor with its Contributor Version (or portions of such
+    combination).
+
+    (c) The licenses granted in Sections 2.2(a) and 2.2(b) are effective
+    on the date Contributor first distributes or otherwise makes the
+    Modifications available to a third party.
+
+    (d) Notwithstanding Section 2.2(b) above, no patent license is
+    granted: (1) for any code that Contributor has deleted from the
+    Contributor Version; (2) for infringements caused by: (i) third
+    party modifications of Contributor Version, or (ii) the combination
+    of Modifications made by that Contributor with other software
+    (except as part of the Contributor Version) or other devices; or (3)
+    under Patent Claims infringed by Covered Software in the absence of
+    Modifications made by that Contributor.
+
+3. Distribution Obligations.
+
+    3.1. Availability of Source Code.
+
+    Any Covered Software that You distribute or otherwise make available
+    in Executable form must also be made available in Source Code form
+    and that Source Code form must be distributed only under the terms
+    of this License. You must include a copy of this License with every
+    copy of the Source Code form of the Covered Software You distribute
+    or otherwise make available. You must inform recipients of any such
+    Covered Software in Executable form as to how they can obtain such
+    Covered Software in Source Code form in a reasonable manner on or
+    through a medium customarily used for software exchange.
+
+    3.2. Modifications.
+
+    The Modifications that You create or to which You contribute are
+    governed by the terms of this License. You represent that You
+    believe Your Modifications are Your original creation(s) and/or You
+    have sufficient rights to grant the rights conveyed by this License.
+
+    3.3. Required Notices.
+
+    You must include a notice in each of Your Modifications that
+    identifies You as the Contributor of the Modification. You may not
+    remove or alter any copyright, patent or trademark notices contained
+    within the Covered Software, or any notices of licensing or any
+    descriptive text giving attribution to any Contributor or the
+    Initial Developer.
+
+    3.4. Application of Additional Terms.
+
+    You may not offer or impose any terms on any Covered Software in
+    Source Code form that alters or restricts the applicable version of
+    this License or the recipients' rights hereunder. You may choose to
+    offer, and to charge a fee for, warranty, support, indemnity or
+    liability obligations to one or more recipients of Covered Software.
+    However, you may do so only on Your own behalf, and not on behalf of
+    the Initial Developer or any Contributor. You must make it
+    absolutely clear that any such warranty, support, indemnity or
+    liability obligation is offered by You alone, and You hereby agree
+    to indemnify the Initial Developer and every Contributor for any
+    liability incurred by the Initial Developer or such Contributor as a
+    result of warranty, support, indemnity or liability terms You offer.
+
+    3.5. Distribution of Executable Versions.
+
+    You may distribute the Executable form of the Covered Software under
+    the terms of this License or under the terms of a license of Your
+    choice, which may contain terms different from this License,
+    provided that You are in compliance with the terms of this License
+    and that the license for the Executable form does not attempt to
+    limit or alter the recipient's rights in the Source Code form from
+    the rights set forth in this License. If You distribute the Covered
+    Software in Executable form under a different license, You must make
+    it absolutely clear that any terms which differ from this License
+    are offered by You alone, not by the Initial Developer or
+    Contributor. You hereby agree to indemnify the Initial Developer and
+    every Contributor for any liability incurred by the Initial
+    Developer or such Contributor as a result of any such terms You offer.
+
+    3.6. Larger Works.
+
+    You may create a Larger Work by combining Covered Software with
+    other code not governed by the terms of this License and distribute
+    the Larger Work as a single product. In such a case, You must make
+    sure the requirements of this License are fulfilled for the Covered
+    Software.
+
+4. Versions of the License.
+
+    4.1. New Versions.
+
+    Oracle is the initial license steward and may publish revised and/or
+    new versions of this License from time to time. Each version will be
+    given a distinguishing version number. Except as provided in Section
+    4.3, no one other than the license steward has the right to modify
+    this License.
+
+    4.2. Effect of New Versions.
+
+    You may always continue to use, distribute or otherwise make the
+    Covered Software available under the terms of the version of the
+    License under which You originally received the Covered Software. If
+    the Initial Developer includes a notice in the Original Software
+    prohibiting it from being distributed or otherwise made available
+    under any subsequent version of the License, You must distribute and
+    make the Covered Software available under the terms of the version
+    of the License under which You originally received the Covered
+    Software. Otherwise, You may also choose to use, distribute or
+    otherwise make the Covered Software available under the terms of any
+    subsequent version of the License published by the license steward.
+
+    4.3. Modified Versions.
+
+    When You are an Initial Developer and You want to create a new
+    license for Your Original Software, You may create and use a
+    modified version of this License if You: (a) rename the license and
+    remove any references to the name of the license steward (except to
+    note that the license differs from this License); and (b) otherwise
+    make it clear that the license contains terms which differ from this
+    License.
+
+5. DISCLAIMER OF WARRANTY.
+
+    COVERED SOFTWARE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
+    WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
+    INCLUDING, WITHOUT LIMITATION, WARRANTIES THAT THE COVERED SOFTWARE
+    IS FREE OF DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR
+    NON-INFRINGING. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF
+    THE COVERED SOFTWARE IS WITH YOU. SHOULD ANY COVERED SOFTWARE PROVE
+    DEFECTIVE IN ANY RESPECT, YOU (NOT THE INITIAL DEVELOPER OR ANY
+    OTHER CONTRIBUTOR) ASSUME THE COST OF ANY NECESSARY SERVICING,
+    REPAIR OR CORRECTION. THIS DISCLAIMER OF WARRANTY CONSTITUTES AN
+    ESSENTIAL PART OF THIS LICENSE. NO USE OF ANY COVERED SOFTWARE IS
+    AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
+
+6. TERMINATION.
+
+    6.1. This License and the rights granted hereunder will terminate
+    automatically if You fail to comply with terms herein and fail to
+    cure such breach within 30 days of becoming aware of the breach.
+    Provisions which, by their nature, must remain in effect beyond the
+    termination of this License shall survive.
+
+    6.2. If You assert a patent infringement claim (excluding
+    declaratory judgment actions) against Initial Developer or a
+    Contributor (the Initial Developer or Contributor against whom You
+    assert such claim is referred to as "Participant") alleging that the
+    Participant Software (meaning the Contributor Version where the
+    Participant is a Contributor or the Original Software where the
+    Participant is the Initial Developer) directly or indirectly
+    infringes any patent, then any and all rights granted directly or
+    indirectly to You by such Participant, the Initial Developer (if the
+    Initial Developer is not the Participant) and all Contributors under
+    Sections 2.1 and/or 2.2 of this License shall, upon 60 days notice
+    from Participant terminate prospectively and automatically at the
+    expiration of such 60 day notice period, unless if within such 60
+    day period You withdraw Your claim with respect to the Participant
+    Software against such Participant either unilaterally or pursuant to
+    a written agreement with Participant.
+
+    6.3. If You assert a patent infringement claim against Participant
+    alleging that the Participant Software directly or indirectly
+    infringes any patent where such claim is resolved (such as by
+    license or settlement) prior to the initiation of patent
+    infringement litigation, then the reasonable value of the licenses
+    granted by such Participant under Sections 2.1 or 2.2 shall be taken
+    into account in determining the amount or value of any payment or
+    license.
+
+    6.4. In the event of termination under Sections 6.1 or 6.2 above,
+    all end user licenses that have been validly granted by You or any
+    distributor hereunder prior to termination (excluding licenses
+    granted to You by any distributor) shall survive termination.
+
+7. LIMITATION OF LIABILITY.
+
+    UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
+    (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE
+    INITIAL DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF
+    COVERED SOFTWARE, OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE
+    TO ANY PERSON FOR ANY INDIRECT, SPECIAL, INCIDENTAL, OR
+    CONSEQUENTIAL DAMAGES OF ANY CHARACTER INCLUDING, WITHOUT
+    LIMITATION, DAMAGES FOR LOSS OF GOODWILL, WORK STOPPAGE, COMPUTER
+    FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL DAMAGES OR
+    LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN INFORMED OF THE
+    POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF LIABILITY SHALL NOT
+    APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY RESULTING FROM SUCH
+    PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW PROHIBITS SUCH
+    LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OR
+    LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS EXCLUSION
+    AND LIMITATION MAY NOT APPLY TO YOU.
+
+8. U.S. GOVERNMENT END USERS.
+
+    The Covered Software is a "commercial item," as that term is defined
+    in 48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
+    software" (as that term is defined at 48 C.F.R. §
+    252.227-7014(a)(1)) and "commercial computer software documentation"
+    as such terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent
+    with 48 C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4
+    (June 1995), all U.S. Government End Users acquire Covered Software
+    with only those rights set forth herein. This U.S. Government Rights
+    clause is in lieu of, and supersedes, any other FAR, DFAR, or other
+    clause or provision that addresses Government rights in computer
+    software under this License.
+
+9. MISCELLANEOUS.
+
+    This License represents the complete agreement concerning subject
+    matter hereof. If any provision of this License is held to be
+    unenforceable, such provision shall be reformed only to the extent
+    necessary to make it enforceable. This License shall be governed by
+    the law of the jurisdiction specified in a notice contained within
+    the Original Software (except to the extent applicable law, if any,
+    provides otherwise), excluding such jurisdiction's conflict-of-law
+    provisions. Any litigation relating to this License shall be subject
+    to the jurisdiction of the courts located in the jurisdiction and
+    venue specified in a notice contained within the Original Software,
+    with the losing party responsible for costs, including, without
+    limitation, court costs and reasonable attorneys' fees and expenses.
+    The application of the United Nations Convention on Contracts for
+    the International Sale of Goods is expressly excluded. Any law or
+    regulation which provides that the language of a contract shall be
+    construed against the drafter shall not apply to this License. You
+    agree that You alone are responsible for compliance with the United
+    States export administration regulations (and the export control
+    laws and regulation of any other countries) when You use, distribute
+    or otherwise make available any Covered Software.
+
+10. RESPONSIBILITY FOR CLAIMS.
+
+    As between Initial Developer and the Contributors, each party is
+    responsible for claims and damages arising, directly or indirectly,
+    out of its utilization of rights under this License and You agree to
+    work with Initial Developer and Contributors to distribute such
+    responsibility on an equitable basis. Nothing herein is intended or
+    shall be deemed to constitute any admission of liability.

+  The GNU General Public License (GPL) Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+51 Franklin Street, Fifth Floor
+Boston, MA 02110-1335
+USA
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public License is
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users. This General Public
+License applies to most of the Free Software Foundation's software and
+to any other program whose authors commit to using it. (Some other Free
+Software Foundation software is covered by the GNU Library General
+Public License instead.) You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price.
+Our General Public Licenses are designed to make sure that you have the
+freedom to distribute copies of free software (and charge for this
+service if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs; and that you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone
+to deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis
+or for a fee, you must give the recipients all the rights that you have.
+You must make sure that they, too, receive or can get the source code.
+And you must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+Finally, any free program is threatened constantly by software patents.
+We wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program
+proprietary. To prevent this, we have made it clear that any patent must
+be licensed for everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and
+modification follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a
+notice placed by the copyright holder saying it may be distributed under
+the terms of this General Public License. The "Program", below, refers
+to any such program or work, and a "work based on the Program" means
+either the Program or any derivative work under copyright law: that is
+to say, a work containing the Program or a portion of it, either
+verbatim or with modifications and/or translated into another language.
+(Hereinafter, translation is included without limitation in the term
+"modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of running
+the Program is not restricted, and the output from the Program is
+covered only if its contents constitute a work based on the Program
+(independent of having been made by running the Program). Whether that
+is true depends on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously
+and appropriately publish on each copy an appropriate copyright notice
+and disclaimer of warranty; keep intact all the notices that refer to
+this License and to the absence of any warranty; and give any other
+recipients of the Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of
+it, thus forming a work based on the Program, and copy and distribute
+such modifications or work under the terms of Section 1 above, provided
+that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any part
+    thereof, to be licensed as a whole at no charge to all third parties
+    under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a notice
+    that there is no warranty (or else, saying that you provide a
+    warranty) and that users may redistribute the program under these
+    conditions, and telling the user how to view a copy of this License.
+    (Exception: if the Program itself is interactive but does not
+    normally print such an announcement, your work based on the Program
+    is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program, and
+can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based on
+the Program, the distribution of the whole must be on the terms of this
+License, whose permissions for other licensees extend to the entire
+whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of a
+storage or distribution medium does not bring the other work under the
+scope of this License.
+
+3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections 1
+    and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your cost
+    of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer to
+    distribute corresponding source code. (This alternative is allowed
+    only for noncommercial distribution and only if you received the
+    program in object code or executable form with such an offer, in
+    accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source code
+means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to control
+compilation and installation of the executable. However, as a special
+exception, the source code distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies the
+executable.
+
+If distribution of executable or object code is made by offering access
+to copy from a designated place, then offering equivalent access to copy
+the source code from the same place counts as distribution of the source
+code, even though third parties are not compelled to copy the source
+along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt otherwise
+to copy, modify, sublicense or distribute the Program is void, and will
+automatically terminate your rights under this License. However, parties
+who have received copies, or rights, from you under this License will
+not have their licenses terminated so long as such parties remain in
+full compliance.
+
+5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and all
+its terms and conditions for copying, distributing or modifying the
+Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further restrictions
+on the recipients' exercise of the rights granted herein. You are not
+responsible for enforcing compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot distribute
+so as to satisfy simultaneously your obligations under this License and
+any other pertinent obligations, then as a consequence you may not
+distribute the Program at all. For example, if a patent license would
+not permit royalty-free redistribution of the Program by all those who
+receive copies directly or indirectly through you, then the only way you
+could satisfy both it and this License would be to refrain entirely from
+distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is implemented
+by public license practices. Many people have made generous
+contributions to the wide range of software distributed through that
+system in reliance on consistent application of that system; it is up to
+the author/donor to decide if he or she is willing to distribute
+software through any other system and a licensee cannot impose that choice.
+
+This section is intended to make thoroughly clear what is believed to be
+a consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License may
+add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among countries
+not thus excluded. In such case, this License incorporates the
+limitation as if written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new
+versions of the General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Program does not specify a version
+number of this License, you may choose any version ever published by the
+Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the
+author to ask for permission. For software which is copyrighted by the
+Free Software Foundation, write to the Free Software Foundation; we

+two goals of preserving the free status of all derivatives of our free
+software and of promoting the sharing and reuse of software generally.
+
+NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO

+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    One line to give the program's name and a brief idea of what it does.
+    Copyright (C) <year> <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful, but
+    WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+    General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1335 USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type
+    `show w'. This is free software, and you are welcome to redistribute
+    it under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License. Of course, the commands
+you use may be called something other than `show w' and `show c'; they
+could even be mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+    Yoyodyne, Inc., hereby disclaims all copyright interest in the
+    program `Gnomovision' (which makes passes at compilers) written by
+    James Hacker.
+
+    signature of Ty Coon, 1 April 1989
+    Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications
+with the library. If this is what you want to do, use the GNU Library
+General Public License instead of this License.
+
+#
+
+Certain source files distributed by Oracle America, Inc. and/or its
+affiliates are subject to the following clarification and special
+exception to the GPLv2, based on the GNU Project exception for its
+Classpath libraries, known as the GNU Classpath Exception, but only
+where Oracle has expressly included in the particular source file's
+header the words "Oracle designates this particular file as subject to
+the "Classpath" exception as provided by Oracle in the LICENSE file
+that accompanied this code."
+
+You should also note that Oracle includes multiple, independent
+programs in this software package. Some of those programs are provided
+under licenses deemed incompatible with the GPLv2 by the Free Software
+Foundation and others.  For example, the package includes programs
+licensed under the Apache License, Version 2.0.  Such programs are
+licensed to you under their original licenses.
+
+Oracle facilitates your further distribution of this package by adding
+the Classpath Exception to the necessary parts of its GPLv2 code, which
+permits you to use that code in combination with other independent
+modules not licensed under the GPLv2.  However, note that this would
+not permit you to commingle code under an incompatible license with
+Oracle's GPLv2 licensed code by, for example, cutting and pasting such
+code into a file also containing Oracle's GPLv2 licensed code and then
+distributing the result.  Additionally, if you were to remove the
+Classpath Exception from any of the files to which it applies and
+distribute the result, you would likely be required to license some or
+all of the other code in that distribution under the GPLv2 as well, and
+since the GPLv2 is incompatible with the license terms of some items
+included in the distribution by Oracle, removing the Classpath
+Exception could therefore effectively compromise your ability to
+further distribute the package.
+
+Proceed with caution and we recommend that you obtain the advice of a
+lawyer skilled in open source matters before removing the Classpath
+Exception or making modifications to this package which may
+subsequently be redistributed and/or involve the use of third party
+software.
+
+CLASSPATH EXCEPTION
+Linking this library statically or dynamically with other modules is
+making a combined work based on this library.  Thus, the terms and
+conditions of the GNU General Public License version 2 cover the whole
+combination.
+
+As a special exception, the copyright holders of this library give you
+permission to link this library with independent modules to produce an
+executable, regardless of the license terms of these independent
+modules, and to copy and distribute the resulting executable under
+terms of your choice, provided that you also meet, for each linked
+independent module, the terms and conditions of the license of that
+module.  An independent module is a module which is not derived from or
+based on this library.  If you modify this library, you may extend this
+exception to your version of the library, but you are not obligated to
+do so.  If you do not wish to do so, delete this exception statement
+from your version.

Subject: [PATCH 1265/1662] Python: Clarify SensitiveAttributeAccess

The comment about imports was placed wrong. I also realized we didn't
even have a single test-case for
`this.(DataFlow::AttrRead).getAttributeNameExpr() = sensitiveLookupStringConst(classification)`
so I added that (notice that this is only `getattr(foo, x)` and not
`getattr(foo, "password")`)

This solution was the best I could come up with, but it _is_ a bit
brittle since you need to remember to add this additional taint step
to any configuration that relies on sensitive data sources... I don't
see an easy way around this though :|

+* Added definitions for types found in `cstdint`. Added types `FixedWidthIntegralType`, `MinimumWidthIntegralType`, `FastestMinimumWidthIntegralType`, and `MaximumWidthIntegralType` to describe types such as `int8_t`, `int_least8_t`, `int_fast8_t`, and `intmax_t` respectively. 
+* Changed definition of `Intmax_t` and `Uintmax_t` to be part of the new type structure. 
+* Added a type `FixedWidthEnumType` which describes enums based on afixed-width integer type. For instance, `enum e: uint8_t = { a, b };`.

Subject: [PATCH 1293/1662] Python: Update .expected for
 py/weak-sensitive-data-hashing

Now there is a path from the _imports_ of the functions that would
return sensitive data, so we produce more alerts.

I'm not entirely happy about this "double reporting", but I'm not sure
how to get around it without either:

1. disabling the extra taint-step for calls. Not ideal since we would
   loose good sources.
2. disabling the extra sources based on function name. Not ideal since
   we would loose good sources.
3. disabling the extra sources based on function name, for those calls
   that would be handled with the extra taint-step for calls. Not ideal
   since that would require running the data-flow query initially to
   prune these out :|

So for now, I think the best approach is to accept some risk on this,
and ship to learn :)

 * Added definitions for types found in `cstdint`. Added types `FixedWidthIntegralType`, `MinimumWidthIntegralType`, `FastestMinimumWidthIntegralType`, and `MaximumWidthIntegralType` to describe types such as `int8_t`, `int_least8_t`, `int_fast8_t`, and `intmax_t` respectively. 
 * Changed definition of `Intmax_t` and `Uintmax_t` to be part of the new type structure. 
-* Added a type `FixedWidthEnumType` which describes enums based on afixed-width integer type. For instance, `enum e: uint8_t = { a, b };`.

Subject: [PATCH 1298/1662] Python: Promote shared type tracking library

This was slightly messier than anticipated, as I hadn't accounted for
the dozen uses of `startInAttr` in our codebase. To circumvent this,
I decided to put the type tracking implementation in the `internal`
directory, and wrap it with a file that ensures the old interface still
works.

Subject: [PATCH 1300/1662] Python: Add `getAMethodCall` to `LocalSourceNode`

This seems like something we have been missing for a while now, so I
figured it might be useful to add. It is roughly based on the JavaScript
equivalent, with one major difference: in the JavaScript libraries,
`getAMethodCall` is reserved for syntactic method calls (`obj.m(...)`)
whereas `getAMemberInvocation` is used for both this and the case where
the bound method `obj.m` is stored in a temporary variable and then
subsequently invoked in the same local scope.

It seems to me that the more general predicate is more useful, and hence
should have the simpler name. (And also we don't really work with a
notion of "invocation" in the Python libraries, so we would need a
better name for it anyway.)

I think as long as the documentation makes the behaviour clear, it
should be okay.

Subject: [PATCH 1307/1662] Python: Fix CWE tag for py/use-of-input

So it better matches what is in `py/code-injection`. I had my doubts
about CWE-95, but after reading
https://owasp.org/www-community/attacks/Direct_Dynamic_Code_Evaluation_Eval%20Injection
I think it's fine to add CWE-95 as well :+1:

Definitions are:

CWE-78: Improper Neutralization of Special Elements used in an OS
Command ('OS Command Injection')

CWE-94: Improper Control of Generation of Code ('Code Injection')

CWE-95: Improper Neutralization of Directives in Dynamically Evaluated
Code ('Eval Injection')

 The CodeQL extension uses the CodeQL CLI to run commands. If you already have the CLI installed and added to your ``PATH``, the extension uses that version. This might be the case if you create your own CodeQL databases instead of downloading them from LGTM.com. Otherwise, the extension automatically manages access to the executable of the CLI for you. For more information about creating databases, see ":ref:`Creating CodeQL databases <creating-codeql-databases>`" in the CLI help.

Subject: [PATCH 1320/1662] Python: Rename .qll file for mysql-connector-python
 support

Just like our support for the `PyYAML` PyPI package that you import with
`import yaml` is in `Yaml.qll`.

Since this file does not provide any public predicates/modules, it
should be safe to rename it.

Subject: [PATCH 1346/1662] Python: Avoid `__main__.py` files as entry points.

According to the official documentation, the purpose of `__main__.py`
files is that their presence in a package (say, `foo`) means one can
execute the package directly using `python -m foo` (which will run the
aforementioned `foo/__main__.py` file).

In principle this means that adding `if __name__ == "__main__"` in these
files is superfluous, as they are only intended to be executed (and not
imported by some other file).

However, in practice people often _do_ include the above construct.
Here are some instances of this on LGTM.com:
https://lgtm.com/query/7521266095072095777/

In particular, 10 out of 33 files in `cpython` have this construct.

This causes some confusion in our module naming, as we usually see the
presence of `__name__ == "__main__"` as an indication that a file may
be run directly (and hence with "absolute import" semantics). However,
when run with `python -m`, the interpreter uses the usual package
semantics, and this leads to modules getting multiple names.

For this reason, I think it makes sense to simply exclude `__main__.py`
files from consideration. Note that if there is a `#!` line mentioning
the Python interpreter, then they will still be included as entry
points.

+/**
+ * INTERNAL use only. This is an experimental API subject to change without notice.
+ *
+ * Provides classes and predicates for dealing with flow models specified in CSV format.
+ *
+ * The CSV specification has the following columns:
+ * - Sources:
+ *   `namespace; type; subtypes; name; signature; ext; output; kind`
+ * - Sinks:
+ *   `namespace; type; subtypes; name; signature; ext; input; kind`
+ * - Summaries:
+ *   `namespace; type; subtypes; name; signature; ext; input; output; kind`
+ *
+ * The interpretation of a row is similar to API-graphs with a left-to-right
+ * reading.
+ * 1. The `namespace` column selects a namespace.
+ * 2. The `type` column selects a type within that namespace.
+ * 3. The `subtypes` is a boolean that indicates whether to jump to an
+ *    arbitrary subtype of that type.
+ * 4. The `name` column optionally selects a specific named member of the type.
+ * 5. The `signature` column optionally restricts the named member. If
+ *    `signature` is blank then no such filtering is done. The format of the
+ *    signature is a comma-separated list of types enclosed in parentheses. The
+ *    types can be short names or fully qualified names (mixing these two options
+ *    is not allowed within a single signature).
+ * 6. The `ext` column specifies additional API-graph-like edges. Currently
+ *    there are only two valid values: "" and "Attribute". The empty string has no
+ *    effect. "Attribute" applies if `name` and `signature` were left blank and
+ *    acts by selecting an element that is attributed with the attribute type
+ *    selected by the first 4 columns. This can be another member such as a field,
+ *    property, method, or parameter.
+ * 7. The `input` column specifies how data enters the element selected by the
+ *    first 6 columns, and the `output` column specifies how data leaves the
+ *    element selected by the first 6 columns. For sinks, an `input` can be either "",
+ *    "Argument[n]", "Argument[n1..n2]", or "ReturnValue":
+ *    - "": Selects a write to the selected element in case this is a field or property.
+ *    - "Argument[n]": Selects an argument in a call to the selected element.
+ *      The arguments are zero-indexed, and `-1` specifies the qualifier.
+ *    - "Argument[n1..n2]": Similar to "Argument[n]" but select any argument in
+ *      the given range. The range is inclusive at both ends.
+ *    - "ReturnValue": Selects a value being returned by the selected element.
+ *      This requires that the selected element is a method with a body.
+ *
+ *    For sources, an `output` can be either "", "Argument[n]", "Argument[n1..n2]",
+ *    "Parameter", "Parameter[n]", "Parameter[n1..n2]", or "ReturnValue":
+ *    - "": Selects a read of a selected field, property, or parameter.
+ *    - "Argument[n]": Selects the post-update value of an argument in a call to the
+ *      selected element. That is, the value of the argument after the call returns.
+ *      The arguments are zero-indexed, and `-1` specifies the qualifier.
+ *    - "Argument[n1..n2]": Similar to "Argument[n]" but select any argument in
+ *      the given range. The range is inclusive at both ends.
+ *    - "Parameter": Selects the value of a parameter of the selected element.
+ *      "Parameter" is also allowed in case the selected element is already a
+ *      parameter itself.
+ *    - "Parameter[n]": Similar to "Parameter" but restricted to a specific
+ *      numbered parameter (zero-indexed, and `-1` specifies the value of `this`).
+ *    - "Parameter[n1..n2]": Similar to "Parameter[n]" but selects any parameter
+ *      in the given range. The range is inclusive at both ends.
+ *    - "ReturnValue": Selects the return value of a call to the selected element.
+ *
+ *    For summaries, `input` and `output` may be prefixed by one of the following,
+ *    separated by the "of" keyword:
+ *    - "Element": Selects an element in a collection.
+ *    - "Field[f]": Selects the contents of field `f`.
+ *    - "Property[p]": Selects the contents of property `p`.
+ *
+ * 8. The `kind` column is a tag that can be referenced from QL to determine to
+ *    which classes the interpreted elements should be added. For example, for
+ *    sources "remote" indicates a default remote flow source, and for summaries
+ *    "taint" indicates a default additional taint step and "value" indicates a
+ *    globally applicable value-preserving step.

+* The following has changed in `Type::getQualifiedName`/`Type::hasQualifiedName`:
+  - Type parameters now have the qualified name of the declaring generic as
+    qualifier, and `<i>` as name, where `i` is the index of the type parameter.
+    Example: in `class C<T> { }`, `T` has qualified name `C.<0>`.
+  - Constructed types now use qualified names for type arguments. For example, the
+    qualified name of `C<int>` is `C<System.Int32>`. This also includes array types
+    and pointer types.
+  - Nested types are now delimited by `+` instead of `.`. For example, the qualified
+    name of `Inner` in `class Outer { class Inner { } }` is `Outer+Inner`.

Subject: [PATCH 1367/1662] Add exactly the string '/' as a sanitizing prefix.

Usually this is ignored for suspicion that it could be taken for a protocol specifier, but on balance the context `(something) + "/" + tainted()` is more likely to be taken for a user-controlled location within a host the user does not control.

 <overview>
 <p>Directly incorporating user input into an HTTP request without validating the input
-can facilitate Server-Side Request Forgery (SSRF) attacks. In these attacks, the server
+can facilitate server-side request forgery (SSRF) attacks. In these attacks, the server
 may be tricked into making a request and interacting with an attacker-controlled server.

Subject: [PATCH 1391/1662] Convert SSRF sinks into url-open CSV sinks

I also drop the previous approach of taint-tracking through various builder objects in favour of assuming that a URI set in a request-builder object is highly likely to end up requested in some way or another.

This will cause the `java/non-https-url` query to pick the new sinks up too, and fixes a Spring case that had never worked but went unnoticed until now.

 * The query "Server-side request forgery (SSRF)" (`java/ssrf`) has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally [submitted as an experimental query by @porcupineyhairs](https://github.com/github/codeql/pull/3454).
+* Models for `URI` and `HttpRequest` in the `java.net` package have been improved. This may lead to more results from any query where these types' methods are relevant.
+* Models for Apache HttpComponents' `RequestLine` and `BasicRequestLine` types. This may lead to more results from any query where these types' methods are relevant.

 * The following has changed in `Type::getQualifiedName`/`Type::hasQualifiedName`:
-  - Type parameters now have the qualified name of the declaring generic as
-    qualifier, and `<i>` as name, where `i` is the index of the type parameter.
-    Example: in `class C<T> { }`, `T` has qualified name `C.<0>`.
+  - Type parameters now have the qualified name which is simply the name of the type
+    parameter itself. Example: in `class C<T> { }`, `T` has qualified name `T`.
   - Constructed types now use qualified names for type arguments. For example, the
     qualified name of `C<int>` is `C<System.Int32>`. This also includes array types
     and pointer types.

+
+<overview>
+<p>
+BeanShell is a small, free, embeddable Java source interpreter with object scripting language 
+features, written in Java. BeanShell dynamically executes standard Java syntax and extends it 
+with common scripting conveniences such as loose types, commands, and method closures like 
+those in Perl and JavaScript. If a BeanShell expression is built using attacker-controlled data, 
+and then evaluated, then it may allow the attacker to run arbitrary code.
+</p>
+</overview>
+
+<recommendation>
+<p>
+It is generally recommended to avoid using untrusted input in a BeanShell expression.
+If it is not possible, BeanShell expressions should be run in a sandbox that allows accessing only
+explicitly allowed classes.
+</p>
+</recommendation>
+
+<example>
+<p>
+The following example uses untrusted data to build and run a BeanShell expression.

+<overview>
+<p>The Java Shell tool (JShell) is an interactive tool for learning the Java programming 
+language and prototyping Java code. JShell is a Read-Evaluate-Print Loop (REPL), which 
+evaluates declarations, statements, and expressions as they are entered and immediately 
+shows the results. If an expression is built using attacker-controlled data and then evaluated, 
+it may allow the attacker to run arbitrary code.</p>
+</overview>
+
+<recommendation>
+<p>It is generally recommended to avoid using untrusted input in a JShell expression.
+If it is not possible,JShell expressions should be run in a sandbox that allows accessing only 
+explicitly allowed classes.</p>
+</recommendation>
+
+<example>
+<p>The following example calls <code>JShell.eval(...)</code> or <code>SourceCodeAnalysis.wrappers(...)</code> 
+to execute untrusted data.</p>

Subject: [PATCH 1454/1662] Python: Clean up `py/insecure-protocol`

Going all the way to the AST layer seemed excessive to me, so I rewrote
it to do most of the logic at the data-flow layer. In principle this
_could_ result in more names being computed (due to splitting), but in
practice I don't expect this make a big difference.

 <overview>
 <p>
-The Spring Framework provides an abstract base class <code>RemoteInvocationSerializingExporter</code>
-for creating remote service exporters.
-A Spring exporter, which is based on this class, deserializes incoming data using <code>ObjectInputStream</code>.
+The Spring Framework provides several classes for creating remote service exporters.
+Under the hood, the exporters use various deserialization mechanisms
+such as <code>ObjectInputStream</code> or Hessian.
 Deserializing untrusted data is easily exploitable and in many cases allows an attacker
-to execute arbitrary code.
-</p>
-<p>
-The Spring Framework also provides <code>HttpInvokerServiceExporter</code>
-and <code>SimpleHttpInvokerServiceExporter</code> classes
-that extend <code>RemoteInvocationSerializingExporter</code>.
+to execute arbitrary code. If a remote attacker can reach endpoints created by the exporters,
+it results in remote code execution in the worst case.
 </p>
+
 <p>
-These classes export specified beans as HTTP endpoints that deserialize data from an HTTP request

+Avoid using unsafe service exporters. Instead, use other message formats for API endpoints (for example, JSON),

 so that deserialization attacks are not possible. If the vulnerable exporters can not be replaced,
 consider using global deserialization filters introduced in JEP 290.

+<overview>
+<p>
+If the <code>checkServerTrusted</code> method of a <code>TrustManager</code> never throws a <code>CertificateException</code> it trusts every certificate.
+This allows an attacker to perform a Man-in-the-middle attack against the application therefore breaking any security Transport Layer Security (TLS) gives.
+
+An attack would look like this:
+1. The program connects to <code>https://example.com</code>.
+2. The attacker intercepts this connection and presents a valid, self-signed certificate for <code>https://example.com</code>.
+3. Java calls the <code>checkServerTrusted</code> method to check whether it should trust the certificate.
+4. The <code>checkServerTrusted</code> method of your <code>TrustManager</code> does not throw a <code>CertificateException</code>.
+5. Java proceeds with the connection since your <code>TrustManager</code> implicitly trusted it by not throwing an exception.
+6. The attacker can now read the data your program sends to <code>https://example.com</code> and/or alter its replies while the program thinks the connection is secure.
+</p>
+</overview>
+
+<recommendation>
+<p>
+Do not use a custom <code>TrustManager</code> that trusts any certificate.
+If you have to use a self-signed certificate, don't trust every certificate, but instead only trust this specific certificate.
+See below for an example of how to do this.
+</p>
+
+</recommendation>
+
+<example>
+<p>
+In the first (bad) example, the <code>TrustManager</code> never throws a <code>CertificateException</code> thereby trusting any certificate.
+This allows an attacker to perform a man-in-the-middle attack.
+In the second (good) example, no custom <code>TrustManager</code> is used. Instead, the self-signed certificate that should be trusted
+is explicitly trusted by loading it into a <code>KeyStore</code>.

 <overview>
-<p>Java offers two mechanisms for SSL authentication - trust manager and hostname verifier (checked by the <code>java/insecure-hostname-verifier</code> query). Trust manager validates the peer's certificate chain while hostname verification establishes that the hostname in the URL matches the hostname in the server's identification.</p>
-<p>And when SSLSocket or SSLEngine is created without a valid parameter of setEndpointIdentificationAlgorithm, hostname verification is disabled by default.</p>
+<p>When SSLSocket or SSLEngine is created without a valid parameter of setEndpointIdentificationAlgorithm, hostname verification is disabled by default.</p>

Subject: [PATCH 1637/1662] Java: Remove "intention-guessing" sanitizer &
 simplify.

This removes the sanitizer part that classified some results as FP
if the results were in methods with certain names, like
`disableVerification()`. I now think that it's a bad idea to filter
based on the method name.
The custom flow steps in `flagFlowStep` are now listed explicitly.
Simplified check whether a method throws an exception.
