[PATCH] Skip writing out sha1 files for objects in packed git.
Now, there's still a misfeature there, which is that when you
create a new object, it doesn't check whether that object
already exists in the pack-file, so you'll end up with a few
recent objects that you really don't need (notably tree
objects), and this patch fixes it.

git-pack-objects: do the delta search in reverse size order
Starting from big objects and going backwards means that we end up
picking a delta that goes from a bigger object to a smaller one. That's
advantageous for two reasons: the bigger object is likely the newer one
(since things tend to grow, rather than shrink), and doing a delete
tends to be smaller than doing an add.
So the deltas don't tend to be top-of-tree, and the packed end result is
just slightly smaller.

git-unpack-objects: start parsing the actual packed data
So far we just print out the type and size.

git-pack-objects: mark the delta packing with a 'D'.
When writing a delta, we take the real type from the object we're
doing the delta against, and just write a 'D' as the type of the
current object.

First cut at git-unpack-objects
So far it just reads the header and generates the list of objects.
It also sorts them by the order they are written in the pack file,
since that ends up being the same order we got them originally, and
is thus "most recent first".

git-pack-objects: create a packed object representation.
This is kind of like a tar-ball for a set of objects, ready to be
shipped off to another end. Alternatively, you could use is as a packed
representation of the object database directly, if you changed
"read_sha1_file()" to read these kinds of packs.
The latter is partiularly useful to generate a "packed history", ie you
could pack up your old history efficiently, but still have it available
(at a performance hit, of course).
I haven't actually written an unpacker yet, so the end result has not
been verified in any way yet. I obviously always write bug-free code,
so it just has to work, no?

git-rev-list: add option to list all objects (not just commits)
When you do
git-rev-list --objects $(git-rev-parse HEAD^..HEAD)
it now lists not only the "commit difference" between the parent of HEAD
and HEAD itself (which is normally just the parent, but in the case of a
merge will be all the newly merged commits), but also all the new tree
and blob objects that weren't in the original.
NOTE! It doesn't walk all the way to the root, so it doesn't do a full
object search in the full old history. Instead, it will only look as
far back in the history as it needs to resolve the commits. Thus, if
the commit reverts a blob (or tree) back to a state much further back in
history, we may end up listing some blobs (or trees) as "new" even
though they exist further back.
Regardless, the list of objects will be a superset (usually exact) list
of objects needed to go from the beginning commit to ending commit.
As a particularly obvious special case,
git-rev-list --objects HEAD
will end up listing every single object that is reachable from the HEAD
commit.
Side note: the objects are sorted by "recency", with commits first.

Add commit row context menu and handle left-click on graph lines
Right-click on a context row now brings up a menu allowing the user to
generate a diff between that row and the selected row. Left-click on
a graph line shows the parent and children connected by the line in
the details pane. Left-click on a circle in the graph selects that
commit. Left-click elsewhere in the graph does nothing.
When displaying a diff, the bottom-right file list box behaves
slightly differently now; instead of eliding all other files' diffs,
it now just scrolls the details pane so that the selected file's diff
starts at the top of the pane.
Since the diffs can be rather large, arrange for an update to be done
every 100ms while reading diffs.
Also removed the CVS revision keywords and bumped the version number
to 1.2.

A "patch ID" is nothing but a SHA1 of the diff associated with a patch,
with whitespace and line numbers ignored. As such, it's "reasonably

that have the same "patch ID" are almost guaranteed to be the same
thing.
IOW, you can use this thing to look for likely duplicate commits.

that tag points to, the tag object really should be removed too.

Do a cross-project merge of Paul Mackerras' gitk visualizer
gitk is really quite incredibly cool, and is great for visualizing what
is going on in a git repository. It's especially useful when you are
looking at what has changed since a particular version, since it
gracefully handles partial trees (and this also avoids the expense of
looking at _all_ changes in a big project).
For example, to see what changed in a merge after a "git pull", do
gitk ORIG_HEAD..
to see only the new things. Or you can simply do "gitk v2.6.12.." to
see what has changed since the v2.6.12 tag etc.
This merge itself is pretty interesting too, since it shows off a
feature of git itself that is incredibly cool: you can merge a
_separate_ git project into another git project. Not only does this
keep all the history of the original project, it also makes it possible
to continue to merge with the original project and the union of the two
projects.
I don't think anybody else can do that.
