#
# This is a template for an options file that can be used to configure
# cvs2svn.  Many options do not have defaults, so it is easier to copy
# this file and modify what you need rather than creating a new
# options file from scratch.
#
# This file is in Python syntax, but you don't need to know Python to
# modify it.  But if you *do* know Python, then you will be happy to
# know that you can use arbitary Python constructs to do fancy
# configuration tricks.
#
# But please be aware of the following:
#
# * In many places, leading whitespace is significant in Python (it is
#   used instead of curly braces to group statements together).
#   Therefore, if you don't know what you are doing, it is best to
#   leave the whitespace as it is.
#
# * In normal strings, Python treats a backslash ("\") as an escape
#   character.  Therefore, if you want to specify a string that
#   contains a backslash, you need either to escape the backslash with
#   another backslash ("\\"), or use a "raw string", as in one if the
#   following equivalent examples:
#
#       cvs_executable = 'c:\\windows\\system32\\cvs.exe'
#       cvs_executable = r'c:\windows\system32\cvs.exe'
#
#   See http://docs.python.org/tutorial/introduction.html#strings for
#   more information.
#
# Two identifiers will have been defined before this file is executed,
# and can be used freely within this file:
#
#     ctx -- a Ctx object (see cvs2svn_lib/context.py), which holds
#         many configuration options
#
#     run_options -- an instance of the SVNRunOptions class (see
#         cvs2svn_lib/svn_run_options.py), which holds some variables
#         governing how cvs2svn is run


# Import some modules that are used in setting the options:

# There are several possible options for where to put the output of a
# cvs2svn conversion.  Please choose one of the following and adjust
# the parameters as necessary:

# Use this output option if you would like cvs2svn to create a new SVN
# repository and store the converted repository there.  The first
# argument is the path to which the repository should be written (this
# repository must not already exist).  The (optional) fs_type argument
# allows a --fs-type option to be passed to "svnadmin create".  The
# (optional) bdb_txn_nosync argument can be specified to set the
# --bdb-txn-nosync option on a bdb repository.  The (optional)
# create_options argument can be specified to set a list of verbatim
# options to be passed to "svnadmin create".  The (optional)
# author_transforms argument allows CVS author names to be transformed
# arbitrarily into SVN author names (as described above):
ctx.output_option = NewRepositoryOutputOption(
    r'/path/to/svnrepo',
    #fs_type='fsfs',
    #bdb_txn_nosync=False,
    #create_options=['--pre-1.5-compatible'],
    #author_transforms=author_transforms,
    )

# Use this output option if you would like cvs2svn to store the
# converted CVS repository into an SVN repository that already exists.
# The first argument is the filesystem path of an existing local SVN
# repository (this repository must already exist).  The
# author_transforms option is as described above:
#ctx.output_option = ExistingRepositoryOutputOption(
#    r'/path/to/svnrepo', # Path to repository
#    #author_transforms=author_transforms,
#    )

# Use this type of output option if you want the output of the
# conversion to be written to a SVN dumpfile instead of committing
# them into an actual repository.  The author_transforms option is as
# described above:
#ctx.output_option = DumpfileOutputOption(
#    dumpfile_path=r'/path/to/cvs2svn-dump', # Name of dumpfile to create
#    #author_transforms=author_transforms,
#    )


# Independent of the ctx.output_option selected, the following option
# can be set to True to suppress cvs2svn output altogether:
ctx.dry_run = False

# The following set of options specifies how the revision contents of
# the RCS files should be read.
#
# The default selection is InternalRevisionReader, which uses built-in
# code that reads the RCS deltas while parsing the files in
# CollectRevsPass.  This method is very fast but requires lots of
# temporary disk space.  The disk space is required for (1) storing
# all of the RCS deltas, and (2) during OutputPass, keeping a copy of
# the full text of every revision that still has a descendant that
# hasn't yet been committed.  Since this can includes multiple
# revisions of each file (i.e., on multiple branches), the required
# amount of temporary space can potentially be many times the size of
# a checked out copy of the whole repository.  Setting compress=True
# cuts the disk space requirements by about 50% at the price of
# increased CPU usage.  Using compression usually speeds up the
# conversion due to the reduced I/O pressure, unless --tmpdir is on a
# RAM disk.  This method does not expand CVS's "Log" keywords.
#
# The second possibility is RCSRevisionReader, which uses RCS's "co"
# program to extract the revision contents of the RCS files during
# OutputPass.  This option doesn't require any temporary space, but it
# is relatively slow because (1) "co" has to be executed very many
# times; and (2) "co" itself has to assemble many file deltas to
# compute the contents of a particular revision.  The constructor
# argument specifies how to invoke the "co" executable.
#
# The third possibility is CVSRevisionReader, which uses the "cvs"
# program to extract the revision contents out of the RCS files during
# OutputPass.  This option doesn't require any temporary space, but it
# is the slowest of all, because "cvs" is considerably slower than
# "co".  However, it works in some situations where RCSRevisionReader
# fails; see the HTML documentation of the "--use-cvs" option for
# details.  The constructor argument specifies how to invoke the "co"
# executable.
#
# Choose one of the following three groups of lines:
ctx.revision_collector = InternalRevisionCollector(compress=True)
ctx.revision_reader = InternalRevisionReader(compress=True)

#ctx.revision_collector = NullRevisionCollector()
#ctx.revision_reader = RCSRevisionReader(co_executable=r'co')

#ctx.revision_collector = NullRevisionCollector()
#ctx.revision_reader = CVSRevisionReader(cvs_executable=r'cvs')

# Set the name (and optionally the path) to the 'svnadmin' command,
# which is needed for NewRepositoryOutputOption or
# ExistingRepositoryOutputOption.  The default is the "svnadmin"
# command in the user's PATH:
#ctx.svnadmin_executable = r'svnadmin'

# Change the following line to True if the conversion should only
# include the trunk of the repository (i.e., all branches and tags
# should be ignored):
ctx.trunk_only = False

# Normally, cvs2svn ignores directories within the CVS repository if
# they do not contain valid RCS files.  This produces a Subversion
# repository whose behavior imitates that of CVS if CVS is typically
# used with the "-P" option.  However, sometimes these empty
# directories are needed by a project (e.g., by the build procedure).
# If so, the following option can be sent to True to cause empty
# directories to be created in the SVN repository when their parent
# directory is created and removed when their parent directory is
# removed.  (This is more likely to be useful than the behavior of CVS
# when its "-P" option is not used.)
ctx.include_empty_directories = False

# CVS symbols.  The rules in a project's symbol_strategy_rules are
# applied in order, and each rule is allowed to modify the symbol.
# The result (after each of the rules has been applied) is used for
# the conversion.
#
# 1. A CVS symbol might be used as a tag in one file and as a branch
#    in another file.  cvs2svn has to decide whether to convert such a
#    symbol as a tag or as a branch.  cvs2svn uses a series of
#    heuristic rules to decide how to convert a symbol.  The user can
#    override the default rules for specific symbols or symbols
#    matching regular expressions.
#
# 2. cvs2svn is also capable of excluding symbols from the conversion
#    (provided no other symbols depend on them.
#
# 3. CVS does not record unambiguously the line of development from
#    which a symbol sprouted.  cvs2svn uses a heuristic to choose a
#    symbol's "preferred parents".
#
# The standard branch/tag/exclude StrategyRules do not change a symbol
# that has already been processed by an earlier rule, so in effect the
# first matching rule is the one that is used.

    #
    # The format of the hints file is described in the documentation
    # for the SymbolHintsFileRule class in
    # cvs2svn_lib/symbol_strategy.py.  The file output by the
    # --write-symbol-info (i.e., ctx.symbol_info_filename) option is
    # in the same format.  The simplest way to use this option is to
    # run the conversion through CollateSymbolsPass with
    # --write-symbol-info option, copy the symbol info and edit it to
    # create a hints file, then re-start the conversion at
    # CollateSymbolsPass with this option enabled.

    # the same content to the trunk as version 1.1.  Normally, such
    # vendor branches are useless and they complicate the SVN history
    # unnecessarily.  The following rule excludes any branches that
    # only existed as a vendor branch with a single import (leaving
    # only the 1.1 revision).  If you want to retain such branches,

# In CVS, it is perfectly possible to make a single commit that
# affects more than one project or more than one branch of a single

# cross-branch CVS commit, it converts it into a
# cross-project/cross-branch Subversion commit.
#
# However, other tools and SCMs have trouble representing
# cross-project or cross-branch commits.  (For example, Trac's Revtree
# plugin, http://www.trac-hacks.org/wiki/RevtreePlugin is confused by
# such commits.)  Therefore, we provide the following two options to
# allow cross-project/cross-branch commits to be suppressed.

# To prevent CVS commits from different projects from being merged

# output, change this option to True:
ctx.keep_cvsignore = False

# By default, it is a fatal error for a CVS ",v" file to appear both
# inside and outside of an "Attic" subdirectory (this should never
# happen, but frequently occurs due to botched repository
# administration).  If you would like to retain both versions of such

# Now use stanzas like the following to define CVS projects that
# should be converted.  The arguments are:
#
# - The filesystem path of the project within the CVS repository.
#
# - The path that should be used for the "trunk" directory of this
#   project within the SVN repository.  This is an SVN path, so it
#   should always use forward slashes ("/").
#
# - The path that should be used for the "branches" directory of this
#   project within the SVN repository.  This is an SVN path, so it
#   should always use forward slashes ("/").
#
# - The path that should be used for the "tags" directory of this
#   project within the SVN repository.  This is an SVN path, so it
#   should always use forward slashes ("/").
#
# - A list of symbol transformations that can be used to rename
#   symbols in this project.  Each entry is a tuple (pattern,
#   replacement), where pattern is a Python regular expression pattern
#   and replacement is the text that should replace the pattern.  Each
#   pattern is matched against each symbol name.  If the pattern
#   matches, then it is replaced with the corresponding replacement
#   text.  The replacement can include substitution patterns (e.g.,
#   r'\1' or r'\g<name>').  Typically you will want to use raw strings
#   (strings with a preceding 'r', like shown in the examples) for the
#   regexp and its replacement to avoid backslash substitution within
#   those strings.
