Description Dennis Gilmore 2013-04-10 03:36:09 UTC

Description of problem:

the output of https://arm.koji.fedoraproject.org/koji/taskinfo?taskID=1696566 shows a lot of comps files. i suspect when updating its including all of the old versions of comps rather than just the one we have now.

Comment 1 Tomas Mlcoch 2013-04-11 07:55:30 UTC

Hi Dennis,
I'm not quite sure if it's a bug or not. This behavior is based on original createrepo and at least my current createrepo-0.9.9-13.fc19 behave in this way. I could change it, that is not a problem.
But I wonder if your version of original createrepo behave differently?

I am looking on a createrepo/createrepo/__init__.py doFinalMove method. This method do (simplified):

1) Move current repodata/ -> old_repodata/
2) Move created .repodata/ -> repodata/
3) Remove primary, filelists, other, repomd, groupfile file from old_repodata/ only if a file with the same name exists in repodata/
4) Build lists: primary, primary_db, filelists, filelists_db, other, other_db which contains corresponding files from old_repodata/, sort them by mtime and except first N (set by --retain-old-md) put them into the old_to_remove list.
5) Iterate over files in old_repodata/. If the current filename is primary.sqlite, filelists.sqlite, other.sqlite or is present in old_to_remove or filename with the same name exists in repodata/ then remove the file and continue. Else if the file with this name doesn't exists in repodata/ move it there.
6) Cleanup (Remove old_repodata etc.)

So if the comps file is changed then its name is changed as well (checksum in the name of file is changed) -> createrepo keep the file during update.
