CVS2SVN(1) User Commands CVS2SVN(1)NAMEcvs2svn - convert a CVS repository into a Subversion repository
SYNOPSIScvs2svn [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 reposi‐
tory to which you only have remote access; see the FAQ for more infor‐
mation. 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 par‐
ent 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.
OPTIONSCONFIGURATION VIA OPTIONS FILE
--options=path
Read the conversion options from path instead of from the com‐
mand line. This option allows far more conversion flexibility
than can be achieved using the command-line alone. See the docu‐
mentation 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, --encod‐
ing, 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 reposi‐
tory 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 mul‐
tiple 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 spec‐
ify a fallback encoding for filenames.) Default: disabled.
--retain-conflicting-attic-files
If a file appears both inside and outside of the CVS attic,
retain the attic version in a subdirectory called 'Attic'. (Nor‐
mally this situation is treated as a fatal error.)
--trunk=path
Set the top-level path to use for trunk in the Subversion repos‐
itory. 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 reposi‐
tory. 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 the
output history. 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, count‐
ing from 0. project-id can be set to '.' if project-specificity
is not needed. symbol-name is the name of the symbol being spec‐
ified. 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 sym‐
bol. 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 'heuris‐
tic' (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 ambigu‐
ous 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 con‐
version. 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 this program needs to gen‐
erate a commit for which CVS does not record the original user‐
name. 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) oth‐
erwise. 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 prop‐
erties.)
--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. The default is to create
a temporary subdirectory under /tmp.
--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 out‐
put.
-v, --verbose
Print more information while running. This option may be speci‐
fied twice to output voluminous debugging information.
-q, --quiet
Print less information while running. This option may be speci‐
fied twice to suppress all non-error output.
--write-symbol-info=path
Write to path symbol statistics and information about how sym‐
bols were converted during CollateSymbolsPass.
--skip-cleanup
Prevent the deletion of temporary files.
--profile
Profile with 'cProfile' (into file cvs2svn.cProfile).
FILES
A directory under /tmp (or the directory specified by --tmpdir) is used
as scratch space for temporary data files.
