Revision 8464010f974245b1e392d34ddbfb914fcf3d8c23 authored by David Steven Tweed on 07 February 2008, 02:55:14 UTC, committed by Junio C Hamano on 11 February 2008, 20:22:58 UTC 
Make git prune remove temporary packs that look like write failures
 
Write errors when repacking (eg, due to out-of-space conditions)
can leave temporary packs (and possibly other files beginning
with "tmp_") lying around which no existing
codepath removes and which aren't obvious to the casual user.
These can also be multi-megabyte files wasting noticeable space.
Unfortunately there's no way to definitely tell in builtin-prune
that a tmp_ file is not being used by a concurrent process,
such as a fetch. However, it is documented that pruning should
only be done on a quiet repository and --expire is honoured
(using code from Johannes Schindelin, along with a test case
he wrote) so that its safety is the same as that of loose
object pruning.

Since they might be signs of a problem (unlike orphaned loose
objects) the names of any removed files are printed.
