Hi all! I tried to figure out how to report bugs and stuff without the collector, but couldn't find anything. Any official way? Anyway, I found this minor bug in FileStorage.py. If you try to pack a db with a packdate that is earlier than the date of the first object in the database, you get a "Errno 22, Invalid argument" error. This is because read_index bails out already at the first object and returns position 4L. Whe _reduntant_pack then tries to seek(-8) it of course fails. Now, I haven't tried tha absolute latest versions of Zope, but a check in the CVS indicated that the problem is still there. I chenged this part of FileStorage.py (row 1275 in v1.71.2.3): packpos, maxoid, ltid = read_index( file, name, index, vindex, tindex, stop, read_only=1, ) if self._redundant_pack(file, packpos): raise FileStorageError, ( 'The database has already been packed to a later time\n' 'or no changes have been made since the last pack') to this: packpos, maxoid, ltid = read_index( file, name, index, vindex, tindex, stop, read_only=1, ) if packpos == 4L or self._redundant_pack(file, packpos): raise FileStorageError, ( 'The database has already been packed to a later time\n' 'or no changes have been made since the last pack') Note the "if packpos == 4l or" part. This means that you get the message that it's already packed. I have also some other small "improvements" (on MailHost, f ex) that I'd like to submit to the community. Well, *I* think it's an improvement. :-)
