This makes git checkout know to use the threaded index preloading if it
is enabled in the config file. You need to have
[core]
preloadindex = true
in your config file to see it, and for that feature to make sense your
filesystem needs to be able to do concurrent 'lstat()' lookups, but when
that is the case (especially NFS over a high-latency network), this can
be a noticeable performance win.
But with a low-latency network and at least older Linux NFS clients, this
will clearly potentially cause a lot of lock contention. It may still
speed up the uncached case, but the threading and locking overhead will
result in the cached case likely slowing down.
That was almost certainly fixed by Linux commit fc0f684c2 ("NFS: Remove
BKL from NFS lookup code"), but that one got merged into 2.6.27-rc1, so
older kernel versions than 2.6.27 will not scale very well.
But regardless, it's the right thing to do. If your filesystem doesn't
scale, don't enable index preloading.

When we ask get_stat_data() to get the mode and size of an index entry,
we can avoid the lstat() call if we have marked the index entry as being
uptodate due to earlier lstat() calls.
This avoids a lot of unnecessary lstat() calls in eg 'git checkout',
where the last phase shows the differences to the working tree
(requiring a diff), but earlier phases have already verified the index.
On the kernel repo (with a fast machine and everything cached), this
changes timings of a nul 'git checkout' from
- Before (best of ten):
0.14user 0.05system 0:00.19elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+13237minor)pagefaults 0swaps
- After
0.11user 0.03system 0:00.15elapsed 98%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+13235minor)pagefaults 0swaps
so it can obviously be noticeable, although equally obviously it's not a
show-stopper on this particular machine. The difference is likely larger
on slower machines, or with operating systems that don't do as good a job
of name caching.

diff -c -p: do not die on submodules

The combine diff logic knew only about blobs (and their checked-out form
in the work tree, either regular files or symlinks), and barfed when fed
submodules. This "externalizes" gitlinks in the same way as the normal
patch generation codepath does (i.e. "Subproject commit Xxx\n") to fix the
issue.

Fix buffer overflow in config parser
|
|
When interpreting a config value, the config parser reads in 1+ space
character(s) and puts -one- space character in the buffer as soon as
the first non-space character is encountered (if not inside quotes).
Unfortunately the buffer size check lacks the extra space character
which gets inserted at the next non-space character, resulting in
a crash with a specially crafted config entry.
The unit test now uses Java to compile a platform independent
.NET framework to output the test string in C# :o)

which replaces the perl invocation.

Ack, ack.
There's another easy 5% or so for the built-in object walker: once we've
created the hash from the name, the name isn't interesting any more, and
so something trivial like this can help a bit.
Does it matter? Probably not on its own. But a few more memory saving
tricks and it might all make a difference.

The name of the processed object was duplicated for passing it to
add_object(), but that already calls path_name, which allocates a new
string anyway. So the memory allocated by the xstrdup calls just went
nowhere, leaking memory.

Embarrassingly, the common prefix calculation did not work properly, due
to a mistake in the assignment: instead of assigning the dirname of the
current file name, the dirname of the current common prefix needs to
be assigned to common prefix, when the current prefix does not match the
current file name.

Users were confused about the meaning and use of the --root option.
Notably, since 68c2ec7 (format-patch: show patch text for the root
commit, 2009-01-10), --root has nothing to do with showing the patch
text for the root commit any more.
Shorten and clarify the corresponding paragraph in the DESCRIPTION
section, document --root under OPTIONS, and add an explicit note that
root commits are formatted regardless.
