bb233d690a Add support for a "GIT_INDEX_FILE" environment variable.
We use that to specify alternative index files, which can be useful
if you want to (for example) generate a temporary index file to do
some specific operation that you don't want to mess with your main
one with.

It defaults to the regular ".git/index" if it hasn't been specified.

94dfb7f2e3 Fix NSEC compile problem, and properly parse the rev-tree cmd line.
The rev-tree thing just happened to work. It shouldn't have.

ca9be05421 Make the sha1 of the index file go at the very end of the file.
This allows us to both calculate it and verify it faster.

4990aadc4c Speed up index file writing by chunking it nicely.
No point in making 17,000 small writes when you can make just
a couple of hundred nice 8kB writes instead and save a lot
of time.

0fcfd160b0 Split up read-cache.c into more logical clumps.
Do the usage and error reporting in "usage.c", and the sha1 file
accesses in "sha1_file.c".

Small, nice, easily separated parts. Good.

a4b7dbef4e [PATCH] fix bug in read-cache.c which loses files when merging a tree
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 fixes show-diff listing all +x files as differring.

c4e3cca1f7 [PATCH] update-cache --remove marks the path merged.
When update-cache --remove is run, resolve unmerged state for
the path.  This is consistent with the update-cache --add
behaviour.  Essentially, the user is telling us how he wants to
resolve the merge by running update-cache.

Fixed to do the right thing at the end.

e44794706e Be much more liberal about the file mode bits.
We only really care about the difference between a file being executable
or not (by its owner). Everything else we leave for the user umask to
decide.

7b937ca331 When inserting a index entry of stage 0, remove all old unmerged entries.

95fd5bf82a Make cache entry comparison take the new "state" flag into account.
This is what allows us to have multiple states of the same file in
the index, and what makes it always sort correctly.

ccc4feb579 Convert the index file reading/writing to use network byte order.
This allows using a git tree over NFS with different byte order, and
makes it possible to just copy a fully populated repository and have
the end result immediately usable (needing just a refresh to update
the stat information).

f864ba7448 Fix read-cache.c collission check logic.
Not only did it test the #define the wrong way around, but
it also leaked file descriptors and VM space. This should
fix it.

bdd4da595a [PATCH] Make nsec checking optional
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.

76e7f4ec48 Fix off-by-one error in removal of cache entry.
Also make the return value of "cache_name_pos()" be sane: positive
or zero if we found it (it's the index into the cache array), and
"-pos-1" to indicate where it should go if we didn't.

73134b6d3f Add "-R" flag to "diff-tree", so that it will recursively traverse a tree of trees
as it diffs them.

This makes diff-tree usable again in the new world order.

121481abf8 Make "update-cache" a bit friendlier to use (and harder to mis-use).
It now requires the "--add" flag before you add any new files, and
a "--remove" file if you want to mark files for removal. And giving
it the "--refresh" flag makes it just update all the files that it
already knows about.

d6d3f9d012 This implements the new "recursive tree" write-tree.
It's got some debugging printouts etc still in it, but testing on the
kernel seems to show that it does indeed fix the issue with huge tree
files for each commit.

197ee8c970 Make "write_cache()" and friends available as generic routines.
This is needed for the change to make "read-tree" just read into the

contents).

734aab758c Make the cache stat information comparator public.
Like the cache filename finder, it's a generically useful function,
rather than something specific to the current "show-diff" thing.

eb38c22f53 Make "cache_name_pos()" available to others.
It finds the cache entry position for a given name, and is
generally useful. Sure, everybody can just scan the active
cache array, but since it's sorted, you actually want to
search it with a binary search, so let's not duplicate that
logic all over the place.

59c1e24980 Fix missing return values and some error tests for empty index files
Patches from Dave Jones and Ingo Molnar, but since I don't have any
infrastructure in place to use the old patch applicator scripts I
am trying to build up, I ended up fixing the thing by hand instead.

Credit where credit is due, though. Nice to see that people are
taking a look at the project even in this early stage.

The tool interface sucks (especially "committing" information, which is just
me doing everything by hand from the command line), but I think this is in
theory actually a viable way of describing the world. So copyright it.
