v0.24.0

Language changes:

• new v0_24_wake API
  • stdlib returns Result instead of BadPath
  • JSON normalization methods
  • 'eor' and 'enor' operators for Booleans
  • 'basename' and 'dirname' path manipulation functions
• combined lrarrow, eqarrow, and ':' precedence into new 'assign' precedence
  • new :-> operator with same precedence as →

Runtime changes:

• .wakeroot can specify a required wake version
• target 'subkey mismatch' is now a warning with a helpful diagnostic
• new wake.db index for faster post-build clean-up
• wake remembers out-of-date files produced by prior runs
• mkdir from wake/fuse now only erase files, not directories
• SI units supported for -m512G
• wake.db now records start/finish times for jobs in nanoseconds
• wake -v -i file now shows the command used to invoke wake
• wake uses umask(0) => can set any permissions with write/mkdir
• wake children now have normalized umask(022) and ulimit(1024)
• runner json includes wake coordinator's hostname
• wake now uses many more file descriptors
  • on linux, wake uses epoll() for scalability
  • tens of thousands of concurrent jobs (previously 500)

Bugfixes:

• wake-fused uses sufficient descriptors to serve mulitple JVMs/etc
• wake no longer hangs with <1 core
• wake --html uses relative path names
• {get,edit}Environment of values with X=Y now work correctly
• publish type errors report their correct locations
• LSP column calculations now work with unicode
• LSP associates comments with operators correctly

v0.23.0

Runtime:

• Added -j and -m to control CPU and memory usage independently
• Wake is now cgroups aware and schedules around the partition's resources
• When no tty is present, info is no longer dumped to stdout

FUSE:

• Finally isolated and fixed the difficult to reproduce 'Could not contact FUSE daemon' bug
• Fixed support for MaxFUSE >= 4

LSP:

• Package version synchronized to wake release version
• Fixed errors for import from nonexistent _ and multiarg matches with a singleton pattern

v0.22.0

New features:

• The wake language now has an implementation of the language server protocol (LSP)
• The entire wake parser was rewritten using lemon and now processes past most errors
• All error messages were rewritten for clarity and homogenized for easy reading

Language changes:

• New v0_22_wake package available for import (v0_19_wake is now deprecated)
• getJobResultOutput and getJobResultOutputs added

Bug fixes:

• FUSE daemon no longer races between open and close
• wake utility is now safe to concurrently invoke (they will run in sequence)

v0.21.0

Language changes:

• Type annotations can be added to patterns. Much of the standard library has type annotations added.
• 'makePlan' now uses the shell to execute the command and accepts a label argument. Use 'makeExecPlan' for the old behavior.
• 'panic' has been renamed as 'unreachable'

New features:

• Wakebox, a new job sandboxing/container tool that builds on fuse-wake. It can replace the Job's filesystem, mount squashfs filesystems and bind-mount parts of the host filesystem. It supports an interactive mode so a user can enter the modified execution environment outside of wake. Fuse-wake is still used by default.

CI / Testing:

• Centos 8 rpm provided.
• Testing framework added to unit test wake itself

Bug fixes:

• .fuse_hidden files are no longer reported as job outputs, as they were fuse filesystem implementation detail.
• The BSP previously only transformed workspace:/// URIs in tags. Now it does it for messages too.
• Fixes for handling of symbolic links

Misc:

• More helpful error message when wake cannot walk the workspace.
• 'claimFileAsPathIn' now uses 'cp', for cases where it's invoked multiple times or used to claim a file from another file system

v0.20.2

Runtime change:

• wake-fuse excludes any generated files named .fuse_hidden as outputs

v0.20.1

Runtime change:

• wake no longer aborts when it cannot enumerate files in a directory

v0.20.0

Language changes:

• Regular expressions now support interpolation using ${}
• setJobTag adds meta-data available to post-build introspection (wake --last / -o / etc)
• Customizable output stream support (see below)
• Build server protocol support (see below)

Runtime changes:

• wake will auto-initialize a database in a directory with a .wakeroot file
• wake no longer schedules more jobs than there is RAM available
• wake sub-targets are now any expression (not just a symbol)
• -q/-v/-d are now short-cuts for --stdout
• default build verbosity was decreased

Custom stream support:

• makeLogLevel creates a new named output stream of a given colour
• streams are selected for output on the wake command-line
  • wake --stdout=stream1,stream2,... controls which streams go to stdout
  • wake --stderr=stream1,steam2,... controls which streams go to stderr
  • wake --fd:3= and --fd:4=- can also be used if these descriptors are connected
• the default streams in wake are:

      name     symbol      colour
      ------------------------------
      -        logNever    -
      debug    logDebug    dark blue
      info     logInfo     -
      echo     logEcho     -
      warning  logWarning  yellow
      error    logError    red

BSP support:

• wake now supports the build server protocol (used mostly by scala)
• the BSP is launched by running bsp-wake with a command-line passed to wake
• BSP requests are serviced using tags called 'bsp.'
• the request bsp.buildTarget is special and results in the Job being listed by workspace/buildTargets

Bugfixes:

• race between exit of the FUSE daemon and a new Job has been fixed
• installIn API now includes a fromDir argument (old version is available in v0_19_wake)
• git submodules are no longer considered source files
• interpolated strings now use canonical unicode for the earlier string segments
• wake now correctly measures memory consumed on linux
• removed a number of places where errors would report a C++ line instead of wake
• wake is no longer confused by branches called xyz.wake
• claimFileAsPath now creates the directory it puts files in

• added diagnostics around bind-mounting the wake-fuse directory
• removed support for centos 6.6 (EOL)

v0.18.2

Changes:

• Improve error handling when a non-visible file is listed as an input

v0.19.1

Changes:

• improve error handling when a non-visible file is listed as an input
