<h2 id="_description">DESCRIPTION</h2>
<div class="sectionbody">
<div class="paragraph"><p><strong>WARNING:</strong> <code>git cvsimport</code> uses cvsps version 2, which is considered
deprecated; it does not work with cvsps version 3 and later. If you are
performing a one-shot import of a CVS repository consider using
<a href="http://cvs2svn.tigris.org/cvs2git.html">cvs2git</a> or
<a href="https://gitlab.com/esr/cvs-fast-export">cvs-fast-export</a>.</p></div>
<div class="paragraph"><p>Imports a CVS repository into Git. It will either create a new
repository, or incrementally import into an existing one.</p></div>
<div class="paragraph"><p>Splitting the CVS log into patch sets is done by <em>cvsps</em>.
At least version 2.1 is required.</p></div>
<div class="paragraph"><p><strong>WARNING:</strong> for certain situations the import leads to incorrect results.
Please see the section <a href="#issues">ISSUES</a> for further reference.</p></div>
<div class="paragraph"><p>You should <strong>never</strong> do any work of your own on the branches that are
created by <em>git cvsimport</em>. By default 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 <em>git merge</em> incremental imports, or
any CVS branches, yourself. It is advisable to specify a named remote via
-r to separate and protect the incoming branches.</p></div>
<div class="paragraph"><p>If you intend to set up a shared public repository that all developers can
read/write, or if you want to use <a href="git-cvsserver.html">git-cvsserver(1)</a>, then you
probably want to make a bare clone of the imported repository,
and use the clone as the shared repository.
See <a href="gitcvs-migration.html">gitcvs-migration(7)</a>.</p></div>
</div>
</div>
<div class="sect1">
<h2 id="_options">OPTIONS</h2>
<div class="sectionbody">
<div class="dlist"><dl>
<dt class="hdlist1">
-v
</dt>
<dd>
<p>
Verbosity: let <em>cvsimport</em> report what it is doing.
</p>
</dd>
<dt class="hdlist1">
-d <CVSROOT>
</dt>
<dd>
<p>
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. If not given, <em>git cvsimport</em> will try to read it
from <code>CVS/Root</code>. If no such file exists, it checks for the
<code>CVSROOT</code> environment variable.
</p>
</dd>
<dt class="hdlist1">
<CVS-module>
</dt>
<dd>
<p>
The CVS module you want to import. Relative to <CVSROOT>.
If not given, <em>git cvsimport</em> tries to read it from
<code>CVS/Repository</code>.
</p>
</dd>
<dt class="hdlist1">
-C <target-dir>
</dt>
<dd>
<p>
The Git repository to import to. If the directory doesn’t
exist, it will be created. Default is the current directory.
</p>
</dd>
<dt class="hdlist1">
-r <remote>
</dt>
<dd>
<p>
The Git remote to import this CVS repository into.
Moves all CVS branches into remotes/<remote>/<branch>
akin to the way <em>git clone</em> uses <em>origin</em> by default.
</p>
</dd>
<dt class="hdlist1">
-o <branch-for-HEAD>
</dt>
<dd>
<p>
When no remote is specified (via -r) the <code>HEAD</code> branch
from CVS is imported to the <em>origin</em> branch within the Git
repository, as <code>HEAD</code> already has a special meaning for Git.
When a remote is specified the <code>HEAD</code> branch is named
remotes/<remote>/master mirroring <em>git clone</em> behaviour.
Use this option if you want to import into a different
branch.
</p>
<div class="paragraph"><p>Use <em>-o master</em> for continuing an import that was initially done by
the old cvs2git tool.</p></div>
</dd>
<dt class="hdlist1">
-i
</dt>
<dd>
<p>
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.
</p>
</dd>
<dt class="hdlist1">
-k
</dt>
<dd>
<p>
Kill keywords: will extract files with <em>-kk</em> from the CVS archive
to avoid noisy changesets. Highly recommended, but off by default
to preserve compatibility with early imported trees.
</p>
</dd>
<dt class="hdlist1">
-u
</dt>
<dd>
<p>
Convert underscores in tag and branch names to dots.
</p>
</dd>
<dt class="hdlist1">
-s <subst>
</dt>
<dd>
<p>
Substitute the character "/" in branch names with <subst>
</p>
</dd>
<dt class="hdlist1">
-p <options-for-cvsps>
</dt>
<dd>
<p>
Additional options for cvsps.
The options <code>-u</code> and <em>-A</em> are implicit and should not be used here.
</p>
<div class="paragraph"><p>If you need to pass multiple options, separate them with a comma.</p></div>
</dd>
<dt class="hdlist1">
-z <fuzz>
</dt>
<dd>
<p>
Pass the timestamp fuzz factor to cvsps, in seconds. If unset,
cvsps defaults to 300s.
</p>
</dd>
<dt class="hdlist1">
-P <cvsps-output-file>
</dt>
<dd>
<p>
Instead of calling cvsps, read the provided cvsps output file. Useful
for debugging or when cvsps is being handled outside cvsimport.
</p>
</dd>
<dt class="hdlist1">
-m
</dt>
<dd>
<p>
Attempt to detect merges based on the commit message. This option
will enable default regexes that try to capture the source
branch name from the commit message.
</p>
</dd>
<dt class="hdlist1">
-M <regex>
</dt>
<dd>
<p>
Attempt to detect merges based on the commit message with a custom
regex. It can be used with <code>-m</code> to enable the default regexes
as well. You must escape forward slashes.
</p>
<div class="paragraph"><p>The regex must capture the source branch name in $1.</p></div>
<div class="paragraph"><p>This option can be used several times to provide several detection regexes.</p></div>
</dd>
<dt class="hdlist1">
-S <regex>
</dt>
<dd>
<p>
Skip paths matching the regex.
</p>
</dd>
<dt class="hdlist1">
-a
</dt>
<dd>
<p>
Import all commits, including recent ones. cvsimport by default
skips commits that have a timestamp less than 10 minutes ago.
</p>
</dd>
<dt class="hdlist1">
-L <limit>
</dt>
<dd>
<p>
Limit the number of commits imported. Workaround for cases where
cvsimport leaks memory.
</p>
</dd>
<dt class="hdlist1">
-A <author-conv-file>
</dt>
<dd>
<p>
CVS by default uses the Unix username when writing its
commit logs. Using this option and an author-conv-file
maps the name recorded in CVS to author name, e-mail and
optional time zone:
</p>
<div class="listingblock">
<div class="content">
<pre><code> exon=Andreas Ericsson <ae@op5.se>
spawn=Simon Pawn <spawn@frog-pond.org> America/Chicago</code></pre>
</div></div>
<div class="paragraph"><p><em>git cvsimport</em> will make it appear as those authors had
their GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL set properly
all along. If a time zone is specified, GIT_AUTHOR_DATE will
have the corresponding offset applied.</p></div>
<div class="paragraph"><p>For convenience, this data is saved to <code>$GIT_DIR/cvs-authors</code>
each time the <em>-A</em> option is provided and read from that same
file each time <em>git cvsimport</em> is run.</p></div>
<div class="paragraph"><p>It is not recommended to use this feature if you intend to
export changes back to CVS again later with
<em>git cvsexportcommit</em>.</p></div>
</dd>
<dt class="hdlist1">
-R
</dt>
<dd>
<p>
Generate a <code>$GIT_DIR/cvs-revisions</code> file containing a mapping from CVS
revision numbers to newly-created Git commit IDs. The generated file
will contain one line for each (filename, revision) pair imported;
each line will look like
</p>
<div class="listingblock">
<div class="content">
<pre><code>src/widget.c 1.1 1d862f173cdc7325b6fa6d2ae1cfd61fd1b512b7</code></pre>
</div></div>
<div class="paragraph"><p>The revision data is appended to the file if it already exists, for use when
doing incremental imports.</p></div>
<div class="paragraph"><p>This option may be useful if you have CVS revision numbers stored in commit
messages, bug-tracking systems, email archives, and the like.</p></div>
</dd>
<dt class="hdlist1">
-h
</dt>
<dd>
<p>
Print a short usage message and exit.
</p>
</dd>
</dl></div>
</div>
</div>
<div class="sect1">
<h2 id="_output">OUTPUT</h2>
<div class="sectionbody">
<div class="paragraph"><p>If <code>-v</code> is specified, the script reports what it is doing.</p></div>
<div class="paragraph"><p>Otherwise, success is indicated the Unix way, i.e. by simply exiting with
a zero exit status.</p></div>

</div>
<div class="sect1">
<h2 id="issues">ISSUES</h2>
<div class="sectionbody">
<div class="paragraph"><p>Problems related to timestamps:</p></div>
<div class="ulist"><ul>
<li>
<p>
If timestamps of commits in the CVS repository are not stable enough
to be used for ordering commits changes may show up in the wrong
order.
</p>
</li>
<li>
<p>
If any files were ever "cvs import"ed more than once (e.g., import of
more than one vendor release) the HEAD contains the wrong content.
</p>
</li>
<li>
<p>
If the timestamp order of different files cross the revision order
within the commit matching time window the order of commits may be
wrong.
</p>
</li>
</ul></div>
<div class="paragraph"><p>Problems related to branches:</p></div>
<div class="ulist"><ul>
<li>
<p>
Branches on which no commits have been made are not imported.
</p>
</li>
<li>
<p>
All files from the branching point are added to a branch even if
never added in CVS.
</p>
</li>
<li>
<p>
This applies to files added to the source branch <strong>after</strong> a daughter
branch was created: if previously no commit was made on the daughter
branch they will erroneously be added to the daughter branch in git.
</p>
</li>
</ul></div>
<div class="paragraph"><p>Problems related to tags:</p></div>
<div class="ulist"><ul>
<li>
<p>
Multiple tags on the same revision are not imported.
</p>
</li>
</ul></div>
<div class="paragraph"><p>If you suspect that any of these issues may apply to the repository you
want to import, consider using cvs2git:</p></div>
