Problem with pack

[Sergio Callegari <scallegari@arces.unibo.it>]

Hi,

I am encountering a problem after a

git repack -a -d

on an archive.

The packet that has been generated appears to be corrupted:

git verify-pack -v pack-ebcdfbbda07e5a3e4136aa1f499990b35685bab4.idx
fatal: failed to read delta-pack base object 
2849bd2bd8a76bbca37df2a4c8e8b990811d01a7

and apparently I might have lost all the history of my project.

I have a few questions:

1) I am working on both a pc and a notebook, syncing the two everytime I 
move from one to the other.
On the PC I have git 1.4.2, on the notebook git 1.4.0. I am using 
"unison" as a syncing tool.
Might the data loss have something to do with...
- the version of git I am using or the mixing of two versions?
- the syncing? I have noticed that after a sync, git is not immediately 
in a happy state... for instance if I run

git diff

git lists diff commands for every file, even if those have not changed. 
However after a

git status

everything seems fine again.

2) git unpack-objects seems to be able to extract some objects from the 
pack, but at a certain point it dies.
- does it die on the first error or does it try to extract everything 
that is possible to extract after the error?
- if it's the first, is there a way to trigger the second behaviour to 
try to save as much as possible from the pack?

Thanks,
