Your CVS repository doesn't have .svnrev file! |
| 154 |
|
|
| 155 |
|
This file is used to keep CVS repository and Subversion in sync, so |
| 156 |
|
that only newer changes will be commited. |
| 157 |
|
|
| 158 |
|
It's quote possible that this is first svn2cvs run for this repository. |
| 159 |
|
If so, you will have to identify correct svn revision which |
| 160 |
|
corresponds to current version of CVS repository that has just |
| 161 |
|
been checkouted. |
| 162 |
|
|
| 163 |
|
If you migrated your cvs repository to svn using cvs2svn, this will be |
| 164 |
|
last Subversion revision. If this is initial run of conversion of |
| 165 |
|
Subversion repository to CVS, correct revision is 0. |

|
|
| 419 |
#cvs commit -m "Automatic commit from SVN" |
./svn2cvs.pl file:///home/dpavlin/private/svn/svn2cvs/trunk/ \ |

|
=head1 DESCRIPTION |
| 423 |
|
|
| 424 |
|
This script will allows you to commit changes made to Subversion repository to |
| 425 |
|
(read-only) CVS repository manually or from Subversion's C<post-commit> hook. |
| 426 |
|
|
| 427 |
|
It's using F<.svnrev> file (which will be created on first run) in |
| 428 |
|
B<CVSROOT/CVSREPOSITORY> to store last Subversion revision which was |
| 429 |
|
committed into CVS. |
| 430 |
|
|
| 431 |
|
One run will do following things: |
| 432 |
|
|
| 433 |
|
=over 4 |
| 434 |
|
|
| 435 |
|
=item * |
| 436 |
|
checkout B<CVSREPOSITORY> from B<CVSROOT> to temporary directory |
| 437 |
|
|
| 438 |
|
=item * |
| 439 |
|
check if F<.svnrev> file exists and create it if it doesn't |
| 440 |
|
|
| 441 |
|
=item * |
| 442 |
|
loop through all revisions from current in B<CVSROOT/CVSREPOSITORY> (using |
| 443 |
|
F<.svnrev>) up to B<HEAD> (current one) |
| 444 |
|
|
| 445 |
|
=over 5 |
| 446 |
|
|
| 447 |
|
=item * |
| 448 |
|
checkout next Subversion revision from B<SVN_URL> over CVS checkout |
| 449 |
|
temporary directory |
| 450 |
|
|
| 451 |
|
=item * |
| 452 |
|
make modification (add and/or delete) done in that revision |
| 453 |
|
|
| 454 |
|
=item * |
| 455 |
|
commit modification (added, deleted or modified files/dirs) while |
| 456 |
|
preserving original message from CVS |
| 457 |
|
|
| 458 |
|
=item * |
| 459 |
|
update F<.svnrev> to match current revision |
| 460 |
|
|
| 461 |
|
=back |
| 462 |
|
|
| 463 |
|
=item * |
| 464 |
|
cleanup temporary directory |
| 465 |
|
|
| 466 |
|
=back |
| 467 |
|
|
| 468 |
|
If checkout fails for some reason (e.g. flaky ssh connection), you will |
| 469 |
|
still have valid CVS repository, so all you have to do is run B<svn2cvs.pl> |
| 470 |
|
again. |
| 471 |
|
|
| 472 |
|
=head1 WARNINGS |
| 473 |
|
|
| 474 |
|
"Cheap" copy operations in Subversion are not at all cheap in CVS. They will |
| 475 |
|
create multiple copies of files in CVS repository! |
| 476 |
|
|
| 477 |
|
This script assume that you want to sync your C<trunk> (or any other |
| 478 |
|
directory for that matter) directory with CVS, not root of your subversion. |
| 479 |
|
This might be considered bug, but since common practise is to have |
| 480 |
|
directories C<trunk> and C<branches> in svn and source code in them, it's |
| 481 |
|
not serious limitation. |
| 482 |
|
|
| 483 |
|
=head1 RELATED PROJECTS |
| 484 |
|
|
| 485 |
|
B<Subversion> L<http://subversion.tigris.org/> version control system that is a |
| 486 |
|
compelling replacement for CVS in the open source community. |
| 487 |
|
|
| 488 |
|
B<cvs2svn> L<http://cvs2svn.tigris.org/> converts a CVS repository to a |
| 489 |
|
Subversion repository. It is designed for one-time conversions, not for |
| 490 |
|
repeated synchronizations between CVS and Subversion. |
| 491 |
|
|
| 492 |
|
=head1 CHANGES |
| 493 |
|
|
| 494 |
|
Versions of this utility are actually Subversion repository revisions, |
| 495 |
|
so they might not be in sequence. |
| 496 |
|
|
| 497 |
|
=over 3 |
| 498 |
|
|
| 499 |
|
=item r10 |
| 500 |
|
|
| 501 |
|
First release available to public |
| 502 |
|
|
| 503 |
|
=item r15 |
| 504 |
|
|
| 505 |
|
Addition of comprehensive documentation, fixes for quoting in commit |
| 506 |
|
messages, and support for skipping changes which are not under current |
| 507 |
|
Subversion checkout root (e.g. branches). |
| 508 |
|
|
| 509 |
|
=item r18 |
| 510 |
|
|
| 511 |
|
Support for importing your svn into empty CVS repository (it will first |
| 512 |
|
create module and than dump all revisions). |
| 513 |
|
Group commit operations to save round-trips to CVS server. |
| 514 |
|
Documentation improvements and other small fixes. |
| 515 |
|
|
| 516 |
|
=item r20 |
| 517 |
|
|
| 518 |
|
Fixed path deduction (overlap between Subversion reporistory and CVS checkout). |
| 519 |
|
|
| 520 |
|
=item r21 |
| 521 |
|
|
| 522 |
|
Use C<update -d> instead of checkout after import. |
| 523 |
|
Added fixes by Paul Egan <paulegan@mail.com> for XMLin and fixing working |
| 524 |
|
directory. |
| 525 |
|
|
| 526 |
|
=item r22 |
| 527 |
|
|
| 528 |
|
Rewritten import from revision 0 to empty repository, better importing |
| 529 |
|
of deep directory structures, initial support for recovery from partial |
| 530 |
|
commit. |
