Sometimes it's just easier to not have to look up the "commit"->"tree"
translation by hand first. It's trivial to do inside diff-tree, and
it's just being polite.
the current cache state and/or working directory.
Very useful to see what has changed since the last commit, either in
the index file or in the whole working directory.
Also very possibly very buggy. Matching the two up is not entirely
trivial.
It's still just a guess, and the result is not a real email
address anyway. If you want to, you can use COMMIT_AUTHOR_EMAIL
to correct for any git guesses.

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.
reading a single tree too. That should speed up a
trivial merge noticeably.
Also, don't bother reading back the tree we just wrote
when we committed a real merge. It had better be the
same one we still have..
Yes, the "parse_commit()" already checks for this condition, but
we need to check for it in rev-tree too, so that we don't start
walking the parent chain unnecessarily.
Doing the latest SCSI merge exposed two bugs in your merge script:
1) It doesn't like a completely new directory (the misc tree contains a
new drivers/scsi/lpfc)
2) the merge testing logic is wrong. You only want to exit 1 if the
merge fails.
My brain just flipped when it tried to read the "Applying" as part
of the explanation of the patch, and the sentence didn't make any
sense. The quotes make it clear what's going on.
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
show_diff_empty() function. Instead, just use show_differences().
This reduces the code size; but more importantly, it is needed for
the later patch to give diff options.

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.

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.

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
any harm to the working directory, but it is confusing.
