\r
279 <h2>DESCRIPTION</h2>
\r
280 <div class="sectionbody">
\r
281 <p>This application is a CVS emulation layer for git.</p>
\r
282 <p>It is highly functional. However, not all methods are implemented,
\r
283 and for those methods that are implemented,
\r
284 not all switches are implemented.</p>
\r
285 <p>Testing has been done using both the CLI CVS client, and the Eclipse CVS
\r
286 plugin. Most functionality works fine with both of these clients.</p>
\r
288 <h2>LIMITATIONS</h2>
\r
289 <div class="sectionbody">
\r
290 <p>Currently cvsserver works over SSH connections for read/write clients, and
\r
291 over pserver for anonymous CVS access.</p>
\r
292 <p>CVS clients cannot tag, branch or perform GIT merges.</p>
\r
294 <h2>INSTALLATION</h2>
\r
295 <div class="sectionbody">
\r
299 If you are going to offer anonymous CVS access via pserver, add a line in
\r
300 /etc/inetd.conf like
\r
302 <div class="listingblock">
\r
303 <div class="content">
\r
304 <pre><tt> cvspserver stream tcp nowait nobody git-cvsserver pserver
\r
307 <p>Note: In some cases, you need to pass the <em>pserver</em> argument twice for
\r
308 git-cvsserver to see it. So the line would look like</p>
\r
309 <div class="listingblock">
\r
310 <div class="content">
\r
311 <pre><tt> cvspserver stream tcp nowait nobody git-cvsserver pserver pserver
\r
314 <p>No special setup is needed for SSH access, other than having GIT tools
\r
315 in the PATH. If you have clients that do not accept the CVS_SERVER
\r
316 env variable, you can rename git-cvsserver to cvs.</p>
\r
320 For each repo that you want accessible from CVS you need to edit config in
\r
321 the repo and add the following section.
\r
323 <div class="listingblock">
\r
324 <div class="content">
\r
327 # optional for debugging
\r
328 logfile=/path/to/logfile
\r
331 <p>Note: you need to ensure each user that is going to invoke git-cvsserver has
\r
332 write access to the log file and to the git repository. When offering anon
\r
333 access via pserver, this means that the nobody user should have write access
\r
334 to at least the sqlite database at the root of the repository.</p>
\r
338 On the client machine you need to set the following variables.
\r
339 CVSROOT should be set as per normal, but the directory should point at the
\r
340 appropriate git repo. For example:
\r
342 <p>For SSH access, CVS_SERVER should be set to git-cvsserver</p>
\r
344 <div class="listingblock">
\r
345 <div class="content">
\r
346 <pre><tt> export CVSROOT=:ext:user@server:/var/git/project.git
\r
347 export CVS_SERVER=git-cvsserver</tt></pre>
\r
352 For SSH clients that will make commits, make sure their .bashrc file
\r
353 sets the GIT_AUTHOR and GIT_COMMITTER variables.
\r
358 Clients should now be able to check out the project. Use the CVS <em>module</em>
\r
359 name to indicate what GIT <em>head</em> you want to check out. Example:
\r
361 <div class="listingblock">
\r
362 <div class="content">
\r
363 <pre><tt> cvs co -d project-master master</tt></pre>
\r
368 <h2>Eclipse CVS Client Notes</h2>
\r
369 <div class="sectionbody">
\r
370 <p>To get a checkout with the Eclipse CVS client:</p>
\r
374 Select "Create a new project -> From CVS checkout"
\r
379 Create a new location. See the notes below for details on how to choose the
\r
385 Browse the <em>modules</em> available. It will give you a list of the heads in
\r
386 the repository. You will not be able to browse the tree from there. Only
\r
392 Pick <em>HEAD</em> when it asks what branch/tag to check out. Untick the
\r
393 "launch commit wizard" to avoid committing the .project file.
\r
397 <p>Protocol notes: If you are using anonymous access via pserver, just select that.
\r
398 Those using SSH access should choose the <em>ext</em> protocol, and configure <em>ext</em>
\r
399 access on the Preferences->Team->CVS->ExtConnection pane. Set CVS_SERVER to
\r
400 <em>git-cvsserver</em>. Not that password support is not good when using <em>ext</em>,
\r
401 you will definitely want to have SSH keys setup.</p>
\r
402 <p>Alternatively, you can just use the non-standard extssh protocol that Eclipse
\r
403 offer. In that case CVS_SERVER is ignored, and you will have to replace
\r
404 the cvs utility on the server with git-cvsserver or manipulate your .bashrc
\r
405 so that calling <em>cvs</em> effectively calls git-cvsserver.</p>
\r
407 <h2>Clients known to work</h2>
\r
408 <div class="sectionbody">
\r
409 <p>CVS 1.12.9 on Debian
\r
410 CVS 1.11.17 on MacOSX (from Fink package)
\r
411 Eclipse 3.0, 3.1.2 on MacOSX (see Eclipse CVS Client Notes)
\r
414 <h2>Operations supported</h2>
\r
415 <div class="sectionbody">
\r
416 <p>All the operations required for normal use are supported, including
\r
417 checkout, diff, status, update, log, add, remove, commit.
\r
418 Legacy monitoring operations are not supported (edit, watch and related).
\r
419 Exports and tagging (tags and branches) are not supported at this stage.</p>
\r
420 <p>The server will set the -k mode to binary when relevant. In proper GIT
\r
421 tradition, the contents of the files are always respected.
\r
422 No keyword expansion or newline munging is supported.</p>

\r
426 <p>git-cvsserver depends on DBD::SQLite.</p>
