Johan Corveleyn commented on SVN-4696:
--------------------------------------
It seems this issue was already confirmed by Bert Huijben in that users@ thread
you linked to. But it wasn't in the issue tracker yet, so thanks for putting it
in here (it doesn't mean this issue will be fixed soon -- that depends on
someone picking it up -- but at least we won't forget about it).
Summarizing some details here in case someone gets to this:
* You probably created this "mirror" with dump+svndumpfilter+load without the
--drop-all-empty-revs option, and without the --renumber-revs option (at least,
that's what was described in that users@ thread).
* This created empty revisions with (apparently) no svn:date property.
* Quoting Bert: "The problem you see is that Subversion doesn’t really have an
index on dates and tries to perform a binary search on the revision properties
to find out which revision you really want based on the date you passed."
Workaround (as suggested by Bert): you should be able to fix this by setting
some appropriate svn:date on all the revisions that now don’t have one, as I
assume your commits in chronological order. For example copying the last seen
date to all revisions that don't have a date.
Now, I see two issues here:
# svndumpfilter without --drop-all-empty-revs and --renumber-revs should
preserve the original svn:date's on empty revisions.
# svn should be able to handle (empty) revisions without svn:date property,
when processing (binary-searching) date-based revision arguments. Not sure what
the desired behaviour should be here, but we should be able to define some sane
behaviour.
