DISCUSSION
|
||||
----------
|
||||
|
||||
git-fsck tests SHA1 and general object sanity, and it does full tracking
|
||||
of the resulting reachability and everything else. It prints out any
|
||||
corruption it finds (missing or bad objects), and if you use the
|
||||
'--unreachable' flag it will also print out objects that exist but
|
||||
that aren't reachable from any of the specified head nodes.
|
||||
|
||||
So for example
|
||||
|
||||
git fsck --unreachable HEAD \
|
||||
$(git for-each-ref --format="%(objectname)" refs/heads)
|
||||
|
||||
will do quite a _lot_ of verification on the tree. There are a few
|
||||
extra validity tests to be added (make sure that tree objects are
|
||||
sorted properly etc), but on the whole if 'git fsck' is happy, you
|
||||
do have a valid tree.
|
||||
'--unreachable' flag it will also print out objects that exist but that
|
||||
aren't reachable from any of the specified head nodes (or the default
|
||||
set, as mentioned above).
|
||||
|
||||
Any corrupt objects you will have to find in backups or other archives
|
||||
(i.e., you can just remove them and do an 'rsync' with some other site in
|
||||
the hopes that somebody else has the object you have corrupted).
|
||||
|
||||
Of course, "valid tree" doesn't mean that it wasn't generated by some
|
||||
evil person, and the end result might be crap. git is a revision
|
||||
tracking system, not a quality assurance system ;)
