302 |
|
svn2cvs - save subversion commits to (read-only) cvs repository |
303 |
|
|
304 |
|
=head1 SYNOPSIS |
305 |
|
|
306 |
|
./svn2cvs.pl SVN_URL CVSROOT CVSREPOSITORY |
307 |
|
|
308 |
|
Usage example (used to self-host this script): |
309 |
|
|
310 |
|
./svn2cvs.pl file:///home/dpavlin/private/svn/svn2cvs/trunk/ \ |
311 |
|
:pserver:dpavlin@cvs.tigris.org:/cvs svn2cvs/src |
312 |
|
|
313 |
|
=head1 DESCRIPTION |
314 |
|
|
315 |
|
This script will allows you to commit changes made to Subversion repository to |
316 |
|
(read-only) CVS repository manually or from Subversion's C<post-commit> hook. |
317 |
|
|
318 |
|
It's using F<.svnrev> file (which will be created on first run) in |
319 |
|
B<CVSROOT/CVSREPOSITORY> to store last Subversion revision which was |
320 |
|
committed into CVS. |
321 |
|
|
322 |
|
One run will do following things: |
323 |
|
|
324 |
|
=over 4 |
325 |
|
|
326 |
|
=item * |
327 |
|
checkout B<CVSREPOSITORY> from B<CVSROOT> to temporary directory |
328 |
|
|
329 |
|
=item * |
330 |
|
check if F<.svnrev> file exists and create it if it doesn't |
331 |
|
|
332 |
|
=item * |
333 |
|
loop through all revisions from current in B<CVSROOT/CVSREPOSITORY> (using |
334 |
|
F<.svnrev>) up to B<HEAD> (current one) |
335 |
|
|
336 |
|
=over 5 |
337 |
|
|
338 |
|
=item * |
339 |
|
checkout next Subversion revision from B<SVN_URL> over CVS checkout |
340 |
|
temporary directory |
341 |
|
|
342 |
|
=item * |
343 |
|
make modification (add and/or delete) done in that revision |
344 |
|
|
345 |
|
=item * |
346 |
|
commit modification (added, deleted or modified files/dirs) while |
347 |
|
preserving original message from CVS |
348 |
|
|
349 |
|
=item * |
350 |
|
update F<.svnrev> to match current revision |
351 |
|
|
352 |
|
=back |
353 |
|
|
354 |
|
=item * |
355 |
|
cleanup temporary directory |
356 |
|
|
357 |
|
=back |
358 |
|
|
359 |
|
If checkout fails for some reason (e.g. flaky ssh connection), you will |
360 |
|
still have valid CVS repository, so all you have to do is run B<svn2cvs.pl> |
361 |
|
again. |
362 |
|
|
363 |
|
=head1 WARNINGS |
364 |
|
|
365 |
|
"Cheap" copy operations in Subversion are not at all cheap in CVS. They will |
366 |
|
create multiple copies of files in CVS repository! |
367 |
|
|
368 |
|
This script assume that you want to sync your C<trunk> (or any other |
369 |
|
directory for that matter) directory with CVS, not root of your subversion. |
370 |
|
This might be considered bug, but since common practise is to have |
371 |
|
directories C<trunk> and C<branches> in svn and source code in them, it's |
372 |
|
not serious limitation. |
373 |
|
|
374 |
|
=head1 RELATED PROJECTS |
375 |
|
|
376 |
|
B<Subversion> L<http://subversion.tigris.org/> version control system that is a |
377 |
|
compelling replacement for CVS in the open source community. |
378 |
|
|
379 |
|
B<cvs2svn> L<http://cvs2svn.tigris.org/> converts a CVS repository to a |
380 |
|
Subversion repository. It is designed for one-time conversions, not for |
381 |
|
repeated synchronizations between CVS and Subversion. |
382 |
|
|
383 |
|
=head1 CHANGES |
384 |
|
|
385 |
|
Versions of this utility are actually Subversion repository revisions, |
386 |
|
so they might not be in sequence. |
387 |
|
|
388 |
|
=over 3 |
389 |
|
|
390 |
|
=item r10 |
391 |
|
|
392 |
|
First release available to public |
393 |
|
|
394 |
|
=item r15 |
395 |
|
|
396 |
|
Addition of comprehensive documentation, fixes for quoting in commit |
397 |
|
messages, and support for skipping changes which are not under current |
398 |
|
Subversion checkout root (e.g. branches). |
399 |
|
|
400 |
|
=item r18 |
401 |
|
|
402 |
|
Support for importing your svn into empty CVS repository (it will first |
403 |
|
create module and than dump all revisions). |
404 |
|
Group commit operations to save round-trips to CVS server. |
405 |
|
Documentation improvements and other small fixes. |
