cvs2git(1)
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.
--cvs-domain=domain
Enables writing cvsusername@domain styleeMail addresses to the
git commits.
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.)
EXTRACTION OPTIONS
--force-keyword-mode=opt
Keyword mode to force, or no to use the default. opt can be
'untouched' (keep literally as they are recorded in the RCS
file), collapsed' (retain the key but not the value),
'expanded' (fake the way CVS expands them, even for binaries),
'kept' (just let CVS deal with keywords).
--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).
INFORMATION OPTIONS
--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.
