Here's a small patch to commit-tree.c that does two things:
- allows the committer email address and name to be overridden
by environment variables (if you don't like the environment
variable names I've used (COMMIT_AUTHOR_NAME,
COMMIT_AUTHOR_EMAIL), feel free to change them.)
- provide the proper domainname to the author/committer email
address (otherwise, my address was only showing up as from the
hostname.)
This allows people to set sane values for the commit names and email
addresses, preventing odd, private hostnames and domains from being
exposed to the world.

This adds -R option to obtain reverse diff.
It may be useful in the merge workflow. After the base of the working
directory is merged and commited, in the working directory:
$ read-tree <tree-id-of-merged-tree>
$ show-diff -R
to re-validate if upstream changes make sense, and/or revert or
conflict with local changes you have in the working files.

This patch removes the custom diff generation code from the

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).
They sure as hell aren't perfect, but they allow you to do:
./git-pull-script {other-git-directory}
to do the initial merge, and if that had content clashes, you do
merge-cache ./git-merge-one-file-script -a
which tries to auto-merge. When/if the auto-merge fails, it will
leave the last file in your working directory, and you can edit
it and then when you're happy you can do "update-cache filename"
on it. Re-do the merge-cache thing until there are no files left
to be merged, and now you can write the tree and commit:
write-tree
commit-tree .... -p $(cat .git/HEAD) -p $(cat .git/MERGE_HEAD)
and you're done.
I noticed this when I tried a non-trivial scsi merge and checked the
results against BK. The problem is that remove_entry_at() actually
decrements active_nr, so decrementing it in add_cache_entry() before
calling remove_entry_at() is a double decrement (hence we lose cache
entries at the end).
This switches to my implementation of merge-base, but with the new parsing
library.

The "update-cache --refresh" command attempts refresh_entry()
on unmerged path, which results in as many "needs update" messages
as there are unmerged stages for that path. This does not do

This simplifies merge-base further. It's now so trivial that it's almost
ridiculous.
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.
- mark_reachable() can be more generic, marking the reachable revisions
with an arbitrary mask.
- date parsing will parse to a date of 0 rather than ULONG_MAX for the
bad old case, sorting the dates correctly.
This also drops the old-style date parsing. We just don't care
enough, since we dropped that format pretty early.
Yes, this could do with some cleanup, and a common library file.

Duh.
When update-cache --remove is run, resolve unmerged state for

When run on unmerged dircache, show-diff compares the working
file with each non-empty stage for that path. Two out of three
times, this is not very helpful. This patch makes it report the
unmergedness only once per each path and avoids running the
actual diff.
Upper layer SCMs like Cogito are expected to find out mode/SHA1
for each stage by using "show-files --stage" and run the diff
itself. This would result in more sensible diffs.
