NAME¶
cvs2svn - convert a cvs repository into a subversion repository
SYNOPSIS¶
cvs2svn [
OPTION]...
OUTPUT-OPTION CVS-REPOS-PATH
cvs2svn [
OPTION]...
--options=PATH
DESCRIPTION¶
Create a new Subversion repository based on the version history stored in a CVS
repository. Each CVS commit will be mirrored in the Subversion repository,
including such information as date of commit and id of the committer.
CVS-REPOS-PATH is the filesystem path of the part of the CVS repository
that you want to convert. It is not possible to convert a CVS repository to
which you only have remote access; see the FAQ for more information. 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).
Multiple CVS repositories can be converted into a single Subversion repository
in a single run of cvs2svn, but only by using an
--options file.
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, and --profile.
OUTPUT OPTIONS¶
- -s, --svnrepos path
- Write the output of the conversion into a Subversion
repository located at path. This option causes a new Subversion
repository to be created at path unless the
--existing-svnrepos option is also used.
- --existing-svnrepos
- Load the converted CVS repository into an existing
Subversion repository, instead of creating a new repository. (This option
should be used in combination with -s/--svnrepos.) The
repository must either be empty or contain no paths that overlap with
those that will result from the conversion. Please note that you need
write permission for the repository files.
- --fs-type
- Pass --fs-type=type to "svnadmin
create" when creating a new repository.
- --bdb-txn-nosync
- Pass --bdb-txn-nosync to "svnadmin create"
when creating a new BDB-style Subversion repository.
- --create-option=opt
- Pass opt to "svnadmin create" when
creating a new Subversion repository (can be specified multiple times to
pass multiple options).
- --dumpfile=path
- Just produce a dumpfile; don't commit to an SVN repository.
Write the dumpfile to path.
- --dry-run
- Do not create a repository or a dumpfile; just print the
details of what cvs2svn would do if it were really converting your
repository.
CONVERSION OPTIONS¶
- --trunk-only
- Convert only trunk commits, not tags nor branches.
- --trunk=path
- Set the top-level path to use for trunk in the Subversion
repository. The default is trunk.
- --branches=path
- Set the top-level path to use for branches in the
Subversion repository. The default is branches.
- --tags=path
- Set the top-level path to use for tags in the Subversion
repository. The default is tags.
- --no-prune
- When all files are deleted from a directory in the
Subversion repository, don't delete the empty directory (the default is to
delete any empty directories.
- --encoding=encoding
- 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=encoding
- 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.
- --symbol-transform=pattern:replacement
- 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 '#').
- --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.)
- --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), or `tag' (treat every ambiguous symbol as a tag). The
default is `heuristic'.
- --keep-cvsignore
- Include .cvsignore files in the output. (Normally
they are unneeded because cvs2svn sets the corresponding svn:ignore
properties.)
- --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.)
- --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.
- --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.)
- --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.
- --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.
- --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.
- --use-internal-co
- Use internal code to extract revision contents. This is up
to 50% faster than using --use-rcs, but needs a lot of disk space:
Roughly the size of your CVS repository plus the peak size of a complete
checkout of the repository with all branches that existed and still had
commits pending at a given time. This option is the default.
- --use-rcs
- Use RCS 'co' to extract revision contents.
- --use-cvs
- Use CVS to extract revision contents (only use this if
having problems with --use-internal-co or --use-rcs, as
those options are much faster).
ENVIRONMENT OPTIONS¶
- --tmpdir=path
- Set the path to use for temporary data. Default is a
directory called cvs2svn-tmp under the current directory.
- --svnadmin=path
- Path to the svnadmin program. (svnadmin is
needed when the -s/--svnrepos output option is used.)
- --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.)
- --sort=path
- Path to the GNU sort program. (cvs2svn requires GNU
sort.)
PARTIAL CONVERSIONS¶
- -p, --pass pass
- Execute only pass pass of the conversion.
pass can be specified by name or by number (see
--help-passes).
- -p, --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.
- -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 symbol statistics and information about how symbols
were converted to path during CollateSymbolsPass.
- --skip-cleanup
- Prevent the deletion of temporary files.
- --profile
- Profile with 'hotshot' (into file
cvs2svn.hotshot).
FILES¶
A directory called
cvs2svn-tmp (or the directory specified by
--tmpdir) is used as scratch space for temporary data files.
