The fmt-merge-msg does a strong syntax checking of its input and fails
with if it is incorrect. The LF character is the only character
important for fmt-merge-msg. As the url in FETCH_HEAD plays only
informational role, a quoted representation of the url should be good
and true enough.
The url often comes from either user-editable config or command line,
so it is reasonable to expect all kinds of characters in it, including
the characters which the format of FETCH_HEAD considers special (line
separator in this case).

This makes it easier for users to get and unset their configuration
variables without having to open documentation or dig through their

__git_config_get_set_variables() retrieves the set configuration

the user has previously specified --global only the global variables
are returned. The same applies for --system, and --file. If no

Pattern matches that fail never assign anything to $1, $2, etc.,
nor do they leave those variables undefined. After an unsuccessful
pattern match, the numeric capture variables remain exactly as they
were before the match was attempted.

The logic in 83ae209 (checkout branch: prime cache-tree fully,

t3900: ISO-2022-JP has more than one popular variants
When converting from other encodings (e.g. EUC-JP or UTF-8), there are
subtly different variants of ISO-2022-JP, all of which are valid. At the
end of line or when a run of string switches to 1-byte sequence, ESC ( B
can be used to switch to ASCII or ESC ( J can be used to switch to ISO
646:JP (JIS X 0201) but they essentially are the same character set and
are used interchangeably. Similarly the set ESC $ @ switches to (JIS X
0208-1978) and ESC $ B switches to (JIS X 0208-1983) are in practice used
interchangeably.
Depending on the iconv library and the locale definition on the system, a
program that converts from another encoding to ISO-2022-JP can produce
different byte sequence, and GIT_TEST_CMP (aka "diff -u") will report the
difference as a failure.
Fix this by converting the expected and the actual output to UTF-8 before
comparing when the end result is ISO-2022-JP. The test vector string in
t3900/ISO-2022-JP.txt is expressed with ASCII and JIS X 0208-1983, but it
can be expressed with any other possible variant, and when converted back
to UTF-8, these variants produce identical byte sequences.

merge-recursive: never leave index unmerged while recursing
When you are trying to come up with the final result (i.e. depth=0), you
want to record how the conflict arose by registering the state of the
common ancestor, your branch and the other branch in the index, hence you
want to do update_stages().
When you are merging with positive depth, that is because of a criss-cross
merge situation. In such a case, you would need to record the tentative
result, with conflict markers and all, as if the merge went cleanly, even
if there are conflicts, in order to write it out as a tree object later to
be used as a common ancestor tree.
update_file() calls update_file_flags() with update_cache=1 to signal that
the result needs to be written to the index at stage #0 (i.e. merged), and
the code should not clobber the index further by calling update_stages().
The codepath to deal with rename/delete conflict in a recursive merge
however left the index unmerged.

Teach 'git checkout' to preload the index contents
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.

Avoid unnecessary 'lstat()' calls in 'get_stat_data()'
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
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.

We try to warn the user if one of their pathspecs caused no

Unfortunately, the file_exists() test was broken for one

This patch detects this special case and acts as if the file
exists (which it must, since it is the project root).

used to complain like:

The alias argv comes from the split_cmdline function, which
splits the config text for the alias into an array of
strings. It returns the number of elements in the array, but
does not actually put a NULL at the end of the array.
Later, the trace function tries to print this argv and
assumes that it has the trailing NULL.
The split_cmdline function is probably at fault, since argv
lists almost always end with a NULL signal. This patch adds
one, in addition to the returned count; this doesn't hurt
the other callers at all, since they were presumably using
the count already (and will never look at the NULL).
