bzr does not automatically create 'obsolete_packs' when it is missing.

[David Cournapeau]

I am seeing those errors again quite frequently on bzr. Full traceback:

I use bzr 1.10 from the PPA on Ubuntu 8.10. Also, I found out that my .bzr is insanely big (~90M, for a couple of MB of data and a few revisions - compressing it gives me a couple of MB only archive).

You have apparently deleted your
/usr/media/boulot/PhdThesis/.bzr/repository/obsolete_packs/ directory.

If you restore your obsolete_packs, packing will work again and your
repository size will go down.

i.e recreate the directory

[Wesley J. Landaker (wjl)]

If the obsolete_packs directory is missing, shouldn't bzr just make it?

[Samuel Bronson (naesten)]

yeah ... shouldn't it?

[Martin Pool (mbp)]

bumping up to high based on the relatively high number of reports and the potential ease of detecting and creating it

[Andrew Cowie (afcowie)]

The meme went around a few years ago that if you were concerned about space, you could delete obsolete_packs. Turns out it meant delete THE obselete packs (ie obselete_packs/*) but not the directory as well. Oops, too late, big mess everywhere.

Does creating an empty obsolete_packs directory again work?

[Jelmer Vernooij (jelmer)]

Obviously we should also just finish Jono's branch and land it..

>Does creating an empty obsolete_packs directory again work?

Yes. The same applies to the 'upload' directory and other directories.
