Ubuntu Manpage: cvs2svn - convert a CVS repository into a Subversion repository

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

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

       -s path, --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=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.

--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.)

--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.

--include-empty-directories
Treat empty subdirectories within the CVS repository as actual directories, creating them when the
parent directory is created and removing them if and when the parent directory is pruned.

--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).

--no-cross-branch-commits
Prevent the creation of commits that affect files on multiple branches at once.

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

       --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-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.

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.)

       --svnadmin=path
              Path to the svnadmin program. (svnadmin is needed when the -s/--svnrepos output 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.
