GIT already did everything I wanted it to do since mid 0.99.7,
and it has almost everything I want it to have now, except a
couple of minor tweaks and enhancements.

- The location of openssl development files got customizable.
- The location of iconv development files got customizable.
- Pass $TAR down to t5000 test so that the user can override with
'gmake TAR=gtar'.
- Solaris 'bc' does not seem to grok "define abs()". There is no
reason to use bc there -- expr would do.

This adds the counterpart of git-update-ref that lets you read
and create "symbolic refs". By default it uses a symbolic link
to represent ".git/HEAD -> refs/heads/master", but it can be compiled
to use the textfile symbolic ref.
The places that did 'readlink .git/HEAD' and 'ln -s refs/heads/blah
.git/HEAD' have been converted to use new git-symbolic-ref command, so
that they can deal with either implementation.

After seeing Jeff's guide, I changed my mind about the
big-rename transition plan. Even if Porcelains are kept up to
date, those web documents that describes older world order would
live longer and people will stumble across them via google
searches. And who knows how many mirrored copies there are.
The backward compatible symbolic links *will* be removed before
1.0. But that will not happen in 0.99.8.

This is a careful version of the script stuff that currently just
blindly writes HEAD with a new value.
You can use
git-update-ref HEAD <newhead>
or
git-update-ref HEAD <newhead> <oldhead>
where the latter version verifies that the old value of HEAD matches
oldhead.
It basically allows a "ref" file to be a symbolic pointer to another ref
file by starting with the four-byte header sequence of "ref:".
More importantly, it allows the update of a ref file to follow these
symbolic pointers, whether they are symlinks or these "regular file
symbolic refs".
NOTE! It follows _real_ symlinks only if they start with "refs/":
otherwise it will just try to read them and update them as a regular file
(ie it will allow the filesystem to follow them, but will overwrite such a
symlink to somewhere else with a regular filename).
In general, using
git-update-ref HEAD "$head"
should be a _lot_ safer than doing
echo "$head" > "$GIT_DIR/HEAD"
both from a symlink following standpoint _and_ an error checking
standpoint. The "refs/" rule for symlinks means that symlinks that point
to "outside" the tree are safe: they'll be followed for reading but not
for writing (so we'll never write through a ref symlink to some other
tree, if you have copied a whole archive by creating a symlink tree).

Some old scripts might still use git-rev-tree, but it really is

git-export was done as a concept example on how easy it is to export
the git data to something else. It's much less powerful than any
number of trivial one-liner scripts now, and real exporters would not
ever use git-export.
It's obviously much less powerful than "git-whatchanged", or just
about any combination of git-rev-list + git-diff-tree.

This is my ARM assembly SHA1 implementation for GIT. It is approximately
50% faster than the generic C version. On an XScale processor running at
400MHz:
generic C version: 9.8 MB/s
my version: 14.5 MB/s
It's not that I expect a lot of big GIT users on ARM, but I stillknow
about one important ARM user that might benefit from it, and writing
that code was fun.
I also reworked the makefile a bit so any optimized SHA1 implementations
is used regardless of whether NO_OPENSSL is defined or not.

Very convenient shorthand for
git-ls-files [file-patterns] | xargs grep <pattern>
which I tend to do all the time.
Yes, it's trivial, but it's really nice. I can do
git grep '\<some_variable\>' arch/i386 include/asm-i386
and it does exactly what you'd think it does. And since it just uses the
normal git-ls-files file patterns, you can do things like
git grep something 'include/*.h'
and it will search all header files under the include/ subdirectory.

I really wanted to try this out, instead of asking for an adjustment

The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.
If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'. Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.
If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree. The user is asked to resolve them by hand and make a
commit manually.
The calling convention from the 'git merge' driver to merge
strategy programs is very simple:
- A strategy program is to be called 'git-merge-<strategy>'.
- They take input of this form:
<common1> <common2> ... '--' <head> <remote1> <remote2>...
That is, one or more the common ancestors, double dash, the
current head, and one or more remote heads being merged into
the current branch.
- Before a strategy program is called, the working tree is
matched to the current <head>.
- The strategy program exits with status code 0 when it
successfully auto-merges the given heads. It should do
update-cache for all the merged paths when it does so -- the
index file will be used to record the merge result as a
commit by the driver.
- The strategy program exits with status code 1 when it leaves
conflicts behind. It should do update-cache for all the
merged paths that it successfully auto-merged, and leave the
cache entry in the index file as the same as <head> for paths
it could not auto-merge, and leave its best-effort result
with conflict markers in the working tree when it does so.
- The strategy program exists with status code other than 0 or
1 if it does not handle the given merge at all.
As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.
