You'd want something like this if you are tracking a git archive
in another SCM format. Notably, we want something like that for
BK users.
This introduces the concept of git "library" objects that
the real programs use, and makes it easier to add such things
to a "libgit.a".
This will also make it trivial to split the current "read-cache.o"
into more aptly named pieces (it does a lot more than just read
the index file).
This switches to my implementation of merge-base, but with the new parsing
library.

This ports fsck-cache to use parsing functions. Note that performance
could be improved here by only reading each object once, but this requires
somewhat more complicated flow control.

This ports rev-tree to use the parsing functions introduced in the
previous patches.

parent of two commits.
The question of "best" commit can probably be tweaked almost arbitrarily.
In particular, trying to take things like how big the tree differences
are into account migt be a good idea. This one is just very simple.
It's there in the history if somebody wants to resurrect it, but it
seems to have been successfully superceded by the new and improved
index-merge thing, where we do all merging entirely in the index.
Ancient cat-file command used to leave temp_git_file_* and there
was support to remove them in the clean target of Makefile. I
do not think it is needed anymore.

The nsec field of ctime/mtime is now checked only with -DNSEC defined during
compilation. nsec acts broken since it is stored in the icache but apparently
just gets to zero when flushed to filesystem not supporting it (e.g. ext3),
creating illusions of false changes. At least that's my impression.

When compiled with -DCOLLISION_CHECK, we will check against SHA1
collisions when writing to the object database.

ls-tree tool provides just a way to export the binary tree objects
to a usable text format. This is bound to be useful in variety
of scripts, although none of those I have currently uses it.
But e.g. the simple script I've sent to HPA for purging the object
database uses it.

I looked a bit at my old BK tools for the same thing, but they were
just so horrid in many ways that I largely rewrote it all and these
tools do things a bit differently. Instead of aggressively piping
data from one process to another (which was clever but very hard
to follow), this first just splits out the mbox into many smaller
email files, and then does some scripts on these temporary files.
tree graph.
It's quite fast when the commit-objects are cached, but since
it has to walk every single commit-object, it also allows you
to cache an old state and just add on top of that.
