| This is a program to convert a CVS repository to Subversion. |
| Bob Miller <kbob@jogger-egg.com> is working on it. |
| |
| ----- |
| |
| Current status (October 1, 2000): |
| |
| cvs2svn.pl can read the whole CVS repository and generate a |
| sorted list of commits, using almost the same heuristic as |
| Karl's cvs2cl.pl. See Commit::accepts_rev for the heuristic. |
| |
| The commits right now are simply of the form: |
| |
| commit |
| path/to/file1 1.23 |
| path/to/file2 1.34 |
| |
| The big task that remains is to produce an XML vdelta that |
| subversion proper (not sure which part) can parse and process. |
| |
| There's a bug in the Rcs package which mixes up log messages |
| and diffs. This means (A) it's not coalescing commits right, |
| and (B) it's wasting a lot of memory storing a large fraction |
| of the repository's diffs. |
| |
| Yes, performance is a problem. See timings below. |
| |
| Packaging is not done: |
| cvs2svn.pl is too big. |
| Rcs.pm is in CPAN, is not in this distribution. |
| CheckedClass.pm is duplicated in cvs2svn.pl, |
| because I was too lazy to set up @INC. |
| Makefile should invoke tests. |
| No documentation. |
| |
| cvs2svn.pl needs about 1,000 more comments than it has. |
