Using the $GIT_OBJECT_DIRECTORY/info/alternates mechanism,
create a new repository that borrows objects from the original
repository when --shared flag is given in addition to --local.
It is worth pointing out that the "cloned" repository depends on
the original repository, so this should be used only when you
can reasonably trust that the original repository would not
disappear without your knowing.

It was a mistake to use GIT_ALTERNATE_OBJECT_DIRECTORIES
environment variable to specify what alternate object pools to
look for missing objects when working with an object database.
It is not a property of the process running the git commands,
but a property of the object database that is partial and needs
other object pools to complete the set of objects it lacks.
This patch allows you to have $GIT_OBJECT_DIRECTORY/info/alternates
whose contents is in exactly the same format as the environment
variable, to let an object database name alternate object pools
it depends on.

[jc: I ended up doing things slightly differently from Yasushi's

free the data portion and keep useing the filespec itself, but
no existing code seems to do things that way, so I just yanked
that part out.]

The index cleanup code is executed via atexit() which is *after* main
has completed, so the stack allocated cache_file has gone out of scope.
Parisc seems to use stack in the destructor functions, so cache_file
gets partially overwritten leading to the predictable disastrous
consequences.
[jc: Just to make sure, I audited other users of the function
hold_index_file_for_update() to make sure they do not have this
problem; everybody else uses non-stack cache_file structure and
is fine. Thanks, James.]

The "get_sha1_hex()" function is designed to work with SHA1 hex strings
that may be followed by arbitrary crud. However, that's not acceptable for
"get_sha1()" which is used for command line arguments etc: we don't want
to silently allow random characters after the end of the SHA1.
So verify that the hex string is all we have.

You can resolve a tag, and it does the right thing except that it might
end up writing the tag itself into the resulting HEAD, which will confuse
subsequent operations no end.
This makes sure that when we resolve two heads, we will have turned them
into proper commits before we start acting on them.
This also fixes the parsing of "treeish^0", which would incorrectly
resolve to "treeish" instead of causing an error.

Also add --verify to make sure the lines you introduced are

This patch renames COPTS to CFLAGS, because it's COPTS that was user
overridable. Also, -Wall is moved there because it's optional. What
was CFLAGS is now ALL_CFLAGS, which users should not override.
Defines are added to DEFINES. Since ALL_CFLAGS is recursively expanded,
it uses the final value of DEFINES.
Implicit rules are made explicit since the implicit rules use CFLAGS
rather than ALL_CFLAGS. I believe that serious projects should not rely
on implicit rules anyway. Percent rules are used because they are used
already and because they don't need the .SUFFIXES target.
[jc: in addition to updating the patch for 0.99.4, I fixed up a

This is a beginning of resurrecting the multi-head pulling support
for git-fetch-pack command. The git-fetch-script wrapper still
only knows about fetching a single head, without renaming, so it is
not very useful unless you directly call git-fetch-pack itself yet.
It also fixes a longstanding obsolete description of how the command
discovers the list of local commits.
In the case where we don't know from context what type an object is, but
we don't have to fetch it, we need to parse it to determine the type
before processing it.

"return" from a test would leave the exit trap set, which could cause a
spurious error message if it's the last test in the script or
--immediate is used.
The easiest solution would be to have a global trap that is set when
test-lib.sh is sourced and unset either by test_done(), error() or by
test_failure_() with --immediate.

I have noticed that "make test" fails without any explanations when the
"merge" utility is missing. I don't think tests should be silent in
case of failure.
It turned out that the particular test was using "exit" to interrupt the
test in case of an error. This caused the whole test script to exit.
No further tests would be run even if "--immediate" wasn't specified.
No error message was printed.
This patch does following:
All instances of "exit", "exit 1" and "(exit 1)" in tests have been
replaced with "return 1". In fact, "(exit 1)" had no effect.
File descriptor 5 is duplicated from file descriptor 1. This is needed
to print important error messages from tests.
New function test_run_() has been introduced. Any "return" in the test
would merely cause that function to return without skipping calls to
test_failure_() and test_ok_(). The new function also traps "exit" and
treats it like a fatal error (in case somebody reintroduces "exit" in
the tests).
test_expect_failure() and test_expect_success() check both the result of
eval and the return value of test_run_(). If the later is not 0, it's
always a failure because it indicates the the test didn't complete.

In commit 4f7eb2e5a3 I fixed git-merge-base
getting confused by datestamps that caused it to traverse things in a
non-obvious order.
However, my fix was a very brute-force one, and it had some really
horrible implications for more complex trees with lots of parallell
development. It might end up traversing all the way to the root commit.
Now, normally that isn't that horrible: it's used mainly for merging, and
the bad cases really tend to happen fairly rarely, so if it takes a few
seconds, we're not in too bad shape.
However, gitk will also do the git-merge-base for every merge it shows,
because it basically re-does the trivial merge in order to show the
"interesting" parts. And there we'd really like the result to be
instantaneous.
This patch does that by walking the tree more completely, and using the
same heuristic as git-rev-list to decide "ok, the rest is uninteresting".
In one - hopefully fairly extreme - case, it made a git-merge-base go from
just under five seconds(!) to a tenth of a second on my machine.

The previous commit improved performance a lot but also meant that
we waited longer to see something drawn. This refines the heuristics
for when to call update so that (1) when we have finished processing
a bufferfull of information from git-rev-list, we call update if
enough time has elapsed, regardless of how many commits we've drawn,
and (2) the number of commits drawn between updates scales with the
total number of commits drawn: 1 for 1-99 commits, 10 for 100-9999
commits, or 100 for >= 10000 commits.
git-rev-parse HEAD^1 would fail, because of an off-by-one bug (but HEAD^
would yield the expected result). Also, when the parent does not exist, do
not silently return an incorrect SHA1. Of course, this no longer applies
to git-rev-parse alone, but every user of get_sha1().
While at it, add a test.

On a large repository with > 60,000 commits, each call to the Tk
update primitive (which gives Tk a chance to respond to events and
redraw the screen) was taking up to 0.2 seconds. Because the logic
was to call update after drawing a commit if 0.1 seconds had passed
since the last update call, we were calling it for every commit,
which was slowing us down enormously. Now we also require that we
have drawn 100 commits since the last update (as well as it being
at least 0.1 seconds since the last update). Drawing 100 commits
takes around 0.1 - 0.2 seconds (even in this large repo) on my G5.
