DESCRIPTION
|
|
-----------
|
|
Imports a CVS repository into git. It will either create a new
|
|
repository, or incrementally import into an existing one.
|
|
|
|
Splitting the CVS log into patch sets is done by 'cvsps'.
|
|
At least version 2.1 is required.
|
|
|
|
You should *never* do any work of your own on the branches that are
|
|
created by git-cvsimport. The initial import will create and populate a
|
|
"master" branch from the CVS repository's main branch which you're free
|
|
to work with; after that, you need to 'git merge' incremental imports, or
|
|
any CVS branches, yourself.
|
|
|
|
OPTIONS
|
|
-------
|
|
-d <CVSROOT>::
|
|
The root of the CVS archive. May be local (a simple path) or remote;
|
|
currently, only the :local:, :ext: and :pserver: access methods
|
|
are supported.
|
|
|
|
-C <target-dir>::
|
|
The git repository to import to. If the directory doesn't
|
|
exist, it will be created. Default is the current directory.
|
|
|
|
-i::
|
|
Import-only: don't perform a checkout after importing. This option
|
|
ensures the working directory and index remain untouched and will
|
|
not create them if they do not exist.
|
|
|
|
-k::
|
|
Kill keywords: will extract files with -kk from the CVS archive
|
|
to avoid noisy changesets. Highly recommended, but off by default
|
|
to preserve compatibility with early imported trees.
|
|
|
|
-u::
|
|
Convert underscores in tag and branch names to dots.
|
|
|
|
-o <branch-for-HEAD>::
|
|
The 'HEAD' branch from CVS is imported to the 'origin' branch within
|
|
the git repository, as 'HEAD' already has a special meaning for git.
|
|
Use this option if you want to import into a different branch.
|
|
+
|
|
Use '-o master' for continuing an import that was initially done by
|
|
the old cvs2git tool.
|
|
|
|
-p <options-for-cvsps>::
|
|
Additional options for cvsps.
|
|
The options '-u' and '-A' are implicit and should not be used here.
|
|
+
|
|
If you need to pass multiple options, separate them with a comma.
|
|
|
|
-P <cvsps-output-file>::
|
|
Instead of calling cvsps, read the provided cvsps output file. Useful
|
|
for debugging or when cvsps is being handled outside cvsimport.
|
|
|
|
-m::
|
|
Attempt to detect merges based on the commit message. This option
|
|
will enable default regexes that try to capture the name source
|
|
branch name from the commit message.
|
|
|
|
-M <regex>::
|
|
Attempt to detect merges based on the commit message with a custom
|
|
regex. It can be used with -m to also see the default regexes.
|
|
You must escape forward slashes.
|
|
|
|
-v::
|
|
Verbosity: let 'cvsimport' report what it is doing.
|
|
|
|
<CVS_module>::
|
|
The CVS module you want to import. Relative to <CVSROOT>.
|
|
|
|
-h::
|
|
Print a short usage message and exit.
|
|
|
|
-z <fuzz>::
|
|
Pass the timestamp fuzz factor to cvsps, in seconds. If unset,
|
|
cvsps defaults to 300s.
|
|
|
|
-s <subst>::
|
|
Substitute the character "/" in branch names with <subst>
|
|
|
|
-a::
|
|
Import all commits, including recent ones. cvsimport by default
|
|
skips commits that have a timestamp less than 10 minutes ago.
|
|
|
|
-S <regex>::
|
|
Skip paths matching the regex.
|
|
|
|
-L <limit>::
|
|
Limit the number of commits imported. Workaround for cases where
|
|
cvsimport leaks memory.
|
|
|
|
-A <author-conv-file>::
|
|
CVS by default uses the Unix username when writing its
|
|
commit logs. Using this option and an author-conv-file
|
|
in this format
|
|
+
|
|
---------
|
|
exon=Andreas Ericsson <ae@op5.se>
|
|
spawn=Simon Pawn <spawn@frog-pond.org>
|
|
|
|
---------
|
|
+
|
|
git-cvsimport will make it appear as those authors had
|
|
their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly
|
|
all along.
|
|
+
|
|
For convenience, this data is saved to $GIT_DIR/cvs-authors
|
|
each time the -A option is provided and read from that same
|
|
file each time git-cvsimport is run.
|
|
+
|
|
It is not recommended to use this feature if you intend to
|
|
export changes back to CVS again later with
|
|
gitlink:git-cvsexportcommit[1].
|
|
|
|
OUTPUT
|
|
------
|
|
If '-v' is specified, the script reports what it is doing.
|
|
|
|
Otherwise, success is indicated the Unix way, i.e. by simply exiting with
|
|
a zero exit status.
