git-rev-list: add "--dense" flag
This is what the recent git-rev-list changes have all been gearing up for.
When we use a path filter to git-rev-list, the new "--dense" flag asks
git-rev-list to compress the history so that it _only_ contains commits
that change files in the path filter. It also rewrites the parent
information so that tools like "gitk" will see the result as a dense
history tree.
For example, on the current kernel archive:
[torvalds@g5 linux]$ git-rev-list HEAD | wc -l
9904
[torvalds@g5 linux]$ git-rev-list HEAD -- kernel | wc -l
5442
[torvalds@g5 linux]$ git-rev-list --dense HEAD -- kernel | wc -l
356
which shows that while we have almost ten thousand commits, we can prune
down the work to slightly more than half by only following the merges
that are interesting. But further, we can then compress the history to
just 356 entries that actually make changes to the kernel subdirectory.
To see this in action, try something like
gitk --dense -- gitk
to see just the history that affects gitk. Or, to show that true
parallel development still remains parallel, do
gitk --dense -- daemon.c
which shows some parallel commits in the current git tree.

Teach git-rev-list to follow just a specified set of files
This is the first cut at a git-rev-list that knows to ignore commits that
don't change a certain file (or set of files).
NOTE! For now it only prunes _merge_ commits, and follows the parent where
there are no differences in the set of files specified. In the long run,
I'd like to make it re-write the straight-line history too, but for now
the merge simplification is much more fundamentally important (the
rewriting of straight-line history is largely a separate simplification
phase, but the merge simplification needs to happen early if we want to
optimize away unnecessary commit parsing).
If all parents of a merge change some of the files, the merge is left as
is, so the end result is in no way guaranteed to be a linear history, but
it will often be a lot /more/ linear than the full tree, since it prunes
out parents that didn't matter for that set of files.
As an example from the current kernel:
[torvalds@g5 linux]$ git-rev-list HEAD | wc -l
9885
[torvalds@g5 linux]$ git-rev-list HEAD -- Makefile | wc -l
4084
[torvalds@g5 linux]$ git-rev-list HEAD -- drivers/usb | wc -l
5206
and you can also use 'gitk' to more visually see the pruning of the
history tree, with something like
gitk -- drivers/usb
showing a simplified history that tries to follow the first parent in a
merge that is the parent that fully defines drivers/usb/.

Split up tree diff functions into tree-diff.c library
This makes the tree diff functionality independent of the "git-diff-tree"
program, by splitting the core functionality up into a library file.
This will be needed for when we teach git-rev-list to only follow a
specified set of pathnames, rather than the global revision history.
Most of it is a fairly straightforward code move, but it also involves
some calling convention cleanup, and moving some of the static variables
from diff-tree.c into the options structure.
The actual tree change callback routines also become paramterized by the
diff_options structure, allowing the library functionality to do something
else than just show the diff on stdout.
Right now the only user of this functionality remains git-diff-tree
itself.

Allow git-merge not to commit.
Martin Langhoff wants to use git-merge from outside git-pull and wants
to do further processing; for this, he wants git-merge no to commit
even when it cleanly merges. I think other script writers would want
something like that as well, so here it is.
Instead of the "merge commit message" parameter (which usually is made
for you by "git-pull" which calls this command), you pass an empty
string to it. Then it will not update your HEAD -- you can do whatever
you want with the resulting index file, which contains the merge results.

Optimize common case of git-rev-list
I took a look at webgit, and it looks like at least for the "projects"
page, the most common operation ends up being basically
git-rev-list --header --parents --max-count=1 HEAD
Now, the thing is, the way "git-rev-list" works, it always keeps on
popping the parents and parsing them in order to build the list of
parents, and it turns out that even though we just want a single commit,
git-rev-list will invariably look up _three_ generations of commits.
It will parse:
- the commit we want (it obviously needs this)
- it's parent(s) as part of the "pop_most_recent_commit()" logic
- it will then pop one of the parents before it notices that it doesn't
need any more
- and as part of popping the parent, it will parse the grandparent (again
due to "pop_most_recent_commit()".
Now, I've strace'd it, and it really is pretty efficient on the whole, but
if things aren't nicely cached, and with long-latency IO, doing those two
extra objects (at a minimum - if the parent is a merge it will be more) is
just wasted time, and potentially a lot of it.
So here's a quick special-case for the trivial case of "just one commit,
and no date-limits or other special rules".

git-fetch-pack: avoid unnecessary zero packing
If everything is up-to-date locally, we don't need to even ask for a
pack-file from the remote, or try to unpack it.
This is especially important for tags - since the pack-file common commit
logic is based purely on the commit history, it will never be able to find
a common tag, and will thus always end up re-fetching them.
Especially notably, if the tag points to a non-commit (eg a tagged tree),
the pack-file would be unnecessarily big, just because it cannot any most
recent common point between commits for pruning.
Short-circuiting the case where we already have that reference means that
we avoid a lot of these in the common case.
NOTE! This only matches remote ref names against the same local name,
which works well for tags, but is not as generic as it could be. If we
ever need to, we could match against _any_ local ref (if we have it, we
have it), but this "match against same name" is simpler and more
efficient, and covers the common case.
Renaming of refs is common for branch heads, but since those are always
commits, the pack-file generation can optimize that case.
In some cases we might still end up fetching pack-files unnecessarily, but
this at least avoids the re-fetching of tags over and over if you use a
regular

If everything is up-to-date locally, we don't need to even ask for a
pack-file from the remote, or try to unpack it.
This is especially important for tags - since the pack-file common commit
logic is based purely on the commit history, it will never be able to find
a common tag, and will thus always end up re-fetching them.
Especially notably, if the tag points to a non-commit (eg a tagged tree),
the pack-file would be unnecessarily big, just because it cannot any most
recent common point between commits for pruning.
Short-circuiting the case where we already have that reference means that
we avoid a lot of these in the common case.

format-patch: take sequence of ranges.
This enhances set of revs you can give format-patch.
Originally, format-patch took either one rev, or two revs:
format-patch rev1
format-patch rev1 rev2
The first format was a short-hand for "format-patch rev1 HEAD"
(i.e. rev2==HEAD). What this meant was to find commits that are
in branch rev2 that has not been merged to branch rev1.
The above notation is still supported, but now it takes sequence
of "from1..to1 from2..to2 ...". In short, the second format has
become a short-hand for "format-patch rev1..rev2". Commits in
to1 but not in from1, to2 but not in from2, ... are formatted as
emailable patches.
With this, cherry-picking from other branch can be written as:
git-format-patch -k --stdout master..branch1 master..branch2 |
git-am -k -3
which is generally faster than traditional cherry-pick (which
always did 3-way merge) if patches apply cleanly, and still
falls back on 3-way merge if some of them do not.

This enhances set of revs you can give format-patch.
Originally, format-patch took either one rev, or two revs:
format-patch rev1
format-patch rev1 rev2
The first format was a short-hand for "format-patch rev1 HEAD"
(i.e. rev2==HEAD). What this meant was to find commits that are
in branch rev2 that has not been merged to branch rev1.
The above notation is still supported, but now it takes sequence
of "from1..to1 from2..to2 ...". In short, the second format has
become a short-hand for "format-patch rev1..rev2". Commits in
to1 but not in from1, to2 but not in from2, ... are formatted as
emailable patches.
With this, cherry-picking from other branch can be written as:
git-format-patch -k --stdout master..branch1 master..branch2 |
git-am -k -3
which is generally faster than traditional cherry-pick (which
always did 3-way merge) if patches apply cleanly, and still
falls back on 3-way merge if some of them do not.

Add "-l" flag for repacking only local packs
This uses the new "--local" flag to git-pack-objects. It currently only
makes a difference together with "-a", since a normal incremental repack
won't pack any packed objects at all (whether local or remote).
Eventually, it might end up skipping any objects that aren't local to
the current object directory, but for now it only knows to skip packed
objects.

Add support for "local" packing
This adds the "--local" flag to git-pack-objects, which acts like
"--incremental", except that instead of ignoring all packed objects, it
only ignores objects that are packed and in an alternate object tree.
As a result, it effectively only does a local re-pack: any remote-packed
objects will stay in the alternate object directories.

Keep track of whether a pack is local or not
If we want to re-pack just local packfiles, we need to know whether a
particular object is local or not.

Adapt tutorial to cygwin and add test case
Lacking reliable symlinks, the instructions in the tutorial did not work
in a cygwin setup. Also, a few outputs were not correct.
This patch fixes these, and adds a test case which follows the
instructions of the tutorial (except git-clone, -fetch and -push, which I
have not done yet).

Add findtags - reworked
A short perl script that will walk the tag refs, tag objects, and even commit
objects in its quest to figure out whether the given SHA1 (for a commit or

Junio.
Usage: git-findtags.perl [ -t ] <commit-or-tree-sha1>

Object references are used in server-info.c:find_pack_info_one() to

Fix packname hash generation.
This changes the generation of hash packfiles have in their names, from
"hash of object names as fed to us" to "hash of object names in the
resulting pack, in the order they appear in the index file". The new
"git-index-pack" command is taught to output the computed hash value
to its standard output.
With this, we can store downloaded pack in a temporary file without
knowing its final name, run git-index-pack to generate idx for it
while finding out its final name, and then rename the pack and idx to
their final names.
