Re: Error converting from 1.4.4.1 to 1.5.0?

... I did try doing this:

1) with 1.4.4.1 git, clone my public repo
2) in this new clone, make modifications to my files as before
3) with 1.5.0 git, do a commit

and I got the same blowup on commit, and this on fsck, with 1.5.0 git:

% git fsck-objects --full
error: Packfile .git/objects/pack/pack-23d1a9af78b4b78d1f3750cf70f83cb91a20ba64.pack SHA1 mismatch with itself
error: 00078437c23cbc04da52233f4f412219f88b8927: object corrupt or missing
fatal: unknown object type 5 in .git/objects/pack/pack-23d1a9af78b4b78d1f3750cf70f83cb91a20ba64.pack

If you stop after cloning but before making a modification, is
the repository in good shape?

% ls -l objects/pack/

The .pack files have the same SHA, but different sizes (don't know
what that means).

That is usually not a problem;  the name reflects the names of
objects contained in the pack (so both have the same set of
objects), but the actual raw contents (and the offsets recorded
in corresponding .idx file) depends on the packing parameters
(window, depth and deltabaseoffset).
