NAME¶
cvs2git - convert a cvs repository into a git repository
SYNOPSIS¶
cvs2git [
OPTION]...
OUTPUT-OPTIONS CVS-REPOS-PATH
cvs2git [
OPTION]...
--options=PATH
DESCRIPTION¶
Create a new git repository based on the version history stored in a CVS
repository. Each CVS commit will be mirrored in the git repository, including
such information as date of commit and id of the committer.
The output of this program are a "blobfile" and a
"dumpfile", which together can be loaded into a git repository using
"git fast-import".
CVS-REPOS-PATH is the filesystem path of the part of the CVS repository
that you want to convert. This path doesn't have to be the top level directory
of a CVS repository; it can point at a project within a repository, in which
case only that project will be converted. This path or one of its parent
directories has to contain a subdirectory called CVSROOT (though the CVSROOT
directory can be empty).
It is not possible directly to convert a CVS repository to which you only have
remote access, but the FAQ describes tools that may be used to create a local
copy of a remote CVS repository.
OPTIONS¶
CONFIGURATION VIA OPTIONS FILE¶
- --options=path
- Read the conversion options from path instead of from the command
line. This option allows far more conversion flexibility than can be
achieved using the command-line alone. See the documentation for more
information. Only the following command-line options are allowed in
combination with --options: -h/--help,
--help-passes, --version, -v/--verbose,
-q/ --quiet, -p/--pass/--passes,
--dry-run, --profile, --trunk-only,
--encoding, and --fallback-encoding. Options are processed
in the order specified on the command line.
OUTPUT OPTIONS¶
- --blobfile=path
- Write the "blob" data (containing revision contents) to
path.
- --dumpfile=path
- Write the revision data (branches and commits) to path.
- --dry-run
- Do not create any output; just print what would happen.
CONVERSION OPTIONS¶
- --trunk-only
- Convert only trunk commits, not tags nor branches.
- --encoding=enc
- Use encoding as the encoding for filenames, log messages, and
author names in the CVS repos. This option may be specified multiple
times, in which case the encodings are tried in order until one succeeds.
Default: ascii. See http://docs.python.org/lib/standard-encodings.html for
a list of other standard encodings.
- --fallback-encoding=enc
- If none of the encodings specified with --encoding succeed in
decoding an author name or log message, then fall back to using
encoding in lossy 'replace' mode. Use of this option may cause
information to be lost, but at least it allows the conversion to run to
completion. This option only affects the encoding of log messages and
author names; there is no fallback encoding for filenames. (By using an
--options file, it is possible to specify a fallback encoding for
filenames.) Default: disabled.
- --retain-conflicting-attic-files
- If a file appears both inside an outside of the CVS attic, retain the
attic version in an SVN subdirectory called 'Attic'. (Normally this
situation is treated as a fatal error.)
SYMBOL HANDLING¶
- --symbol-transform=p:s
- Transform RCS/CVS symbol names before entering them into Subversion.
pattern is a Python regexp pattern that is matches against the
entire symbol name; replacement is a replacement using Python's
regexp reference syntax. You may specify any number of these options; they
will be applied in the order given on the command line.
- --symbol-hints=path
- Read symbol conversion hints from path. The format of path
is the same as the format output by --write-symbol-info, namely a
text file with four whitespace-separated columns: project-id,
symbol, conversion, and parent-lod-name.
project-id is the numerical ID of the project to which the symbol
belongs, counting from 0. project-id can be set to '.' if
project-specificity is not needed. symbol-name is the name of the
symbol being specified. conversion specifies how the symbol should
be converted, and can be one of the values 'branch', 'tag', or
´exclude'. If conversion is '.', then this rule does not
affect how the symbol is converted. parent-lod-name is the name of
the symbol from which this symbol should sprout, or '.trunk.' if the
symbol should sprout from trunk. If parent-lod-name is omitted or
'.', then this rule does not affect the preferred parent of this symbol.
The file may contain blank lines or comment lines (lines whose first
non-whitespace character is '#').
- --symbol-default=opt
- Specify how to convert ambiguous symbols (those that appear in the CVS
archive as both branches and tags). opt must be 'heuristic' (decide
how to treat each ambiguous symbol based on whether it was used more often
as a branch/tag in CVS), 'strict' (no default; every ambiguous symbol has
to be resolved manually using --force-branch, --force-tag,
or --exclude), 'branch' (treat every ambiguous symbol as a branch),
'tag' (treat every ambiguous symbol as a tag), or 'exclude' (do not
convert ambiguous symbols). The default is 'heuristic'.
- --force-branch=regexp
- Force symbols whose names match regexp to be branches.
regexp must match the whole symbol name.
- --force-tag=regexp
- Force symbols whose names match regexp to be tags. regexp
must match the whole symbol name.
- --exclude=regexp
- Exclude branches and tags whose names match regexp from the
conversion. regexp must match the whole symbol name.
- --keep-trivial-imports
- Do not exclude branches that were only used for a single import. (By
default such branches are excluded because they are usually created by the
inappropriate use of cvs import.)
SUBVERSION PROPERTIES¶
- --username=name
- Set the default username to name when cvs2svn needs to generate a
commit for which CVS does not record the original username. This happens
when a branch or tag is created. The default is to use no author at all
for such commits.
- --auto-props=file
- Specify a file in the format of Subversion's config file, whose
[auto-props] section can be used to set arbitrary properties on files in
the Subversion repository based on their filenames. (The [auto-props]
section header must be present; other sections of the config file,
including the enable-auto-props setting, are ignored.) Filenames are
matched to the filename patterns case-insensitively.
- --mime-types=file
- Specify an apache-style mime.types file for setting
svn:mime-type.
- --eol-from-mime-type
- For files that don't have the kb expansion mode but have a known mime
type, set the eol-style based on the mime type. For such files, set
svn:eol-style to "native" if the mime type begins with
"text/", and leave it unset (i.e., no EOL translation)
otherwise. Files with unknown mime types are not affected by this option.
This option has no effect unless the --mime-types option is also
specified.
- --default-eol=style
- Set svn:eol-style to style for files that don't have the CVS
´kb' expansion mode and whose end-of-line translation mode hasn't
been determined by one of the other options. style must be 'binary'
(default), 'native', 'CRLF', 'LF', or 'CR'.
- --keywords-off
- By default, cvs2svn sets svn:keywords on CVS files to "author id
date" if the mode of the RCS file in question is either kv, kvl or
unset. If you use the --keywords-off switch, cvs2svn will not set
svn:keywords for any file. While this will not touch the keywords in the
contents of your files, Subversion will not expand them.
- --keep-cvsignore
- Include .cvsignore files in the output. (Normally they are unneeded
because cvs2svn sets the corresponding svn:ignore properties.)
- --cvs-revnums
- Record CVS revision numbers as file properties in the Subversion
repository. (Note that unless it is removed explicitly, the last CVS
revision number will remain associated with the file even after the file
is changed within Subversion.)
- --use-cvs
- Use CVS to extract revision contents. This option is slower than
--use-internal-co or --use-rcs.
- --use-rcs
- Use RCS 'co' to extract revision contents. This option is faster than
--use-cvs but fails in some cases.
- --use-external-blob-generator
- Use an external Python program to extract the file revision contents from
the RCS files and output them to the blobfile. This option is much faster
than --use-rcs or --use-cvs but leaves keywords unexpanded
and requires a separate, seekable blob file to write to in parallel to the
main cvs2git script.
ENVIRONMENT OPTIONS¶
- --tmpdir=path
- Set the path to use for temporary data. Default is a directory
called cvs2svn-tmp under the current directory.
- --co=path
- Path to the co program. (co is needed if the
--use-rcs option is used.)
- --cvs=path
- Path to the cvs program. (cvs is needed if the
--use-cvs option is used.)
PARTIAL CONVERSIONS¶
- --pass=pass
- Execute only pass pass of the conversion. pass can be
specified by name or by number (see --help-passes).
- -p [start]:[end], --passes=[start]:[end]
- Execute passes start through end of the conversion
(inclusive). start and end can be specified by name or by
number (see --help-passes). If start or end is
missing, it defaults to the first or last pass, respectively. For this to
work the earlier passes must have been completed before on the same CVS
repository, and the generated data files must be in the temporary
directory (see --tmpdir).
- --version
- Print the version number.
- -h, --help
- Print the usage message and exit with success.
- --help-passes
- Print the numbers and names of the conversion passes and exit with
success.
- --man
- Output the unix-style manpage for this program to standard output.
- -v, --verbose
- Print more information while running. This option may be specified twice
to output voluminous debugging information.
- -q, --quiet
- Print less information while running. This option may be specified twice
to suppress all non-error output.
- --write-symbol-info=path
- Write to path symbol statistics and information about how symbols
were converted during CollateSymbolsPass.
- --skip-cleanup
- Prevent the deletion of temporary files.
- --profile
- Profile with 'cProfile' (into file cvs2svn.cProfile).
FILES¶
A directory called
cvs2svn-tmp (or the directory specified by
--tmpdir) is used as scratch space for temporary data files.
