If you have a CVS checkout, it is easy to import the CVS history by calling "git cvsimport". However, interacting with the CVS repository using "git cvsexportcommit" was cumbersome, since that script assumes separate working directories for Git and CVS. Now, you can call cvsexportcommit with the -W option. This will automatically discover the GIT_DIR, and it will check out the parent commit before exporting the commit. The intended workflow is this: $ CVSROOT=$URL cvs co module $ cd module $ git cvsimport hack, hack, hack, making two commits, cleaning them up using rebase -i. $ git cvsexportcommit -W -c -p -u HEAD^ $ git cvsexportcommit -W -c -p -u HEAD Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

NAME

|
git-cvsexportcommit - Export a single commit to a CVS checkout
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
'git-cvsexportcommit' [-h] [-u] [-v] [-c] [-P] [-p] [-a] [-d cvsroot] [-w cvsworkdir] [-W] [-f] [-m msgprefix] [PARENTCOMMIT] COMMITID
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
Exports a commit from GIT to a CVS checkout, making it easier
|
|
to merge patches from a git repository into a CVS repository.
|
|
|
|
Specify the name of a CVS checkout using the -w switch or execute it
|
|
from the root of the CVS working copy. In the latter case GIT_DIR must
|
|
be defined. See examples below.
|
|
|
|
It does its best to do the safe thing, it will check that the files are
|
|
unchanged and up to date in the CVS checkout, and it will not autocommit
|
|
by default.
|
|
|
|
Supports file additions, removals, and commits that affect binary files.
|
|
|
|
If the commit is a merge commit, you must tell git-cvsexportcommit what parent
|
|
should the changeset be done against.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
-c::
|
|
Commit automatically if the patch applied cleanly. It will not
|
|
commit if any hunks fail to apply or there were other problems.
|
|
|
|
-p::
|
|
Be pedantic (paranoid) when applying patches. Invokes patch with
|
|
--fuzz=0
|
|
|
|
-a::
|
|
Add authorship information. Adds Author line, and Committer (if
|
|
different from Author) to the message.
|
|
|
|
-d::
|
|
Set an alternative CVSROOT to use. This corresponds to the CVS
|
|
-d parameter. Usually users will not want to set this, except
|
|
if using CVS in an asymmetric fashion.
|
|
|
|
-f::
|
|
Force the merge even if the files are not up to date.
|
|
|
|
-P::
|
|
Force the parent commit, even if it is not a direct parent.
|
|
|
|
-m::
|
|
Prepend the commit message with the provided prefix.
|
|
Useful for patch series and the like.
|
|
|
|
-u::
|
|
Update affected files from CVS repository before attempting export.
|
|
|
|
-w::
|
|
Specify the location of the CVS checkout to use for the export. This
|
|
option does not require GIT_DIR to be set before execution if the
|
|
current directory is within a git repository.
|
|
|
|
-W::
|
|
Tell cvsexportcommit that the current working directory is not only
|
|
a Git checkout, but also the CVS checkout. Therefore, Git will
|
|
reset the working directory to the parent commit before proceeding.
|
|
|
|
-v::
|
|
Verbose.
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
Merge one patch into CVS::
|
|
+
|
|
------------
|
|
$ export GIT_DIR=~/project/.git
|
|
$ cd ~/project_cvs_checkout
|
|
$ git-cvsexportcommit -v <commit-sha1>
|
|
$ cvs commit -F .msg <files>
|
|
------------
|
|
|
|
Merge one patch into CVS (-c and -w options). The working directory is within the Git Repo::
|
|
+
|
|
------------
|
|
$ git-cvsexportcommit -v -c -w ~/project_cvs_checkout <commit-sha1>
|
|
------------
|
|
|
|
Merge pending patches into CVS automatically -- only if you really know what you are doing::
|
|
+
|
|
------------
|
|
$ export GIT_DIR=~/project/.git
|
|
$ cd ~/project_cvs_checkout
|
|
$ git-cherry cvshead myhead | sed -n 's/^+ //p' | xargs -l1 git-cvsexportcommit -c -p -v
