It looks like the old cvs Attic got seriously decluttered recently, before the svn conversion. I see: $ tar tjvf plplot-cvsroot.20070225.tar.bz2 |grep Attic| wc -l 1341 $ tar tjvf plplot-cvsroot.20070304.tar.bz2 |grep Attic| wc -l 51 which is an awful lot of history lost between the dates shown. I have backups, so no biggie, but I'm still pretty surprised. Anyone know what happened to them? -- Maurice LeBrun |

Indeed, missing Attic files in our CVS repository would be a tremendous blow to preserving the history of our project. Therefore, I am hugely relieved that I _don't_ see this issue for the backup that I did of the final frozen version of our CVS repository that was used for the subversion conversion. tar ztvf plplot-cvsroot.tar.gz_20070329 |grep Attic |wc -l 1347 Maurice, it smells like you had a bad backup on March 4 (although I don't see how rsync could be that unreliable). Do you get good results if you take a cvs backup now? rsync of our frozen CVS repository should continue to work, and your results on the number of Attic'd files should be identical to mine.

My last rsync of the locked repo looks ok. I don't know why, but there have been a lot of bogus ones lately. Here are all the Attic files in my recent backups ("last" being Thursday morning before the switchover). plplot-cvsroot.20070225.tar.bz2 1341 plplot-cvsroot.20070304.tar.bz2 51 plplot-cvsroot.20070311.tar.bz2 51 plplot-cvsroot.20070318.tar.bz2 51 plplot-cvsroot.20070325.tar.bz2 51 plplot-cvsroot.last.tar.bz2 319 plplot-cvsroot.locked.tar.bz2 1347 So at least the final result looks good.. no idea what happened with those others. -- Maurice LeBrun |

Maybe we just got out in time? :-) I am really glad you confirm the 1347 Attic'd files in the final result. Also, if your late February and most of March results are an indication of some lingering CVS problem at SF, it appears I picked a good time to do the conversion! >From my CVS versus SVN consistency tests I am completely confident that we have everything that could be reasonably extracted from the locked version in our current SVN version. However, if there were something wrong with the locked CVS version (such as missing Attic files), my tests would not have seen it. Therefore, Maurice, thanks for making this important cross-check, and I encourage you to look further for other anomalies (if any) in the "locked" CVS version that I have depended on for the conversion. Also, I encourage all developers here to read the trunk, tags, and branches of our current SVN to make sure it delivers what you think it should for the current HEAD and the historical branches/tags that interest you. Better to find out now if there are any lurking problems, rather than two months down the road. Alan __________________________ Alan W.

I also set up the locked repo as a local cvs repo on my home network, synced it with my old (uncommitted) projects and did a cvs diff.. everything looks fine. So migrating any of that forward (as I have the time and/or need) shouldn't be hard. -- Maurice LeBrun |
