Commit 5b0864070 (sha1_object_info_extended: make type calculation
optional, Jul 12 2013) changed the return value of the
sha1_object_info_extended function to 0/-1 for success/error.
Previously this function returned the object type for success or
-1 for error. But unfortunately the above commit forgot to change
or move the comment above this function that says "returns enum
object_type or negative".
To fix this inconsistency, let's move the comment above the
sha1_object_info function where it is still true.

In a number of tests, output that was produced by a shell script is
compared to expected output using test_cmp. Unfortunately, the MSYS bash--
when invoked via git, such as in hooks--converts LF to CRLF on output
(as produced by echo and printf), which leads to many false positives.
Implements a diff tool that undoes the converted CRLF. To avoid that
sub-processes are spawned (which is very slow on Windows), the tool is
implemented as a shell function. Diff is invoked as usual only when a
difference is detected by the shell code.

Users may set test_cmp to a comparison tool of their liking. The intent is
that the tool performs comparison of line-oriented texts. However, t5300
uses it also to compare binary data. Change those tests to use 'cmp'.

This function was added in d2b0708 (2008-09-27, add have_git_dir()
function) as a preparation for adbc0b6 (2008-09-30, cygwin: Use native
Win32 API for stat).
However the second referenced commit was reverted in f66450a (2013-06-22,
cygwin: Remove the Win32 l/stat() implementation), so we don't need to
expose this wrapper function any more as a public API.

The function 'invalidate_ref_cache' was introduced in 79c7ca5 (2011-10-17,
invalidate_ref_cache(): rename function from invalidate_cached_refs())
by a rename and elevated to be publicly usable in 8be8bde (2011-10-17,
invalidate_ref_cache(): expose this function in the refs API)
However it is not used anymore, as 8bf90dc (2011-10-17, write_ref_sha1():
only invalidate the loose ref cache) and (much) later 506a760 (2013-04-22,
refs: change how packed refs are deleted) removed any calls to this
function. So it seems as if we don't need that function any more,
good bye!

The add--interactive --patch mode adjusts the UI based on
whether we are pulling changes from HEAD or elsewhere (in
the former case it asks to unstage the reverse hunk, rather
than apply the forward hunk).
Commit 166ec2e taught reset to work on an unborn branch, but
in doing so, switched to always providing add--interactive
with the sha1 rather than the symbolic name. This meant we
always used the "apply" interface, even for "git reset -p
HEAD".
We can fix this by passing the symbolic name to
add--interactive. Since it understands unborn branches
these days, we do not even have to cover this special case
ourselves; we can simply pass HEAD.
The tests in t7105 now check that the right interface is
used in each circumstance (and notice the regression from
166ec2e we are fixing). The test in t7106 checks that we
get this right for the unborn case, too (not a regression,
since it didn't work at all before, but a nice improvement).

The list_modified function already knows how to handle an
unborn branch by diffing against the empty tree. However,
the diff we perform to get the actual hunks does not. Let's
use the same logic for both diffs.

In shorten_unambiguous_ref, we build and cache a reverse-map of the
rev-parse rules like this:
static char **scanf_fmts;
static int nr_rules;
if (!nr_rules) {
for (; ref_rev_parse_rules[nr_rules]; nr_rules++)
... generate scanf_fmts ...
}
where ref_rev_parse_rules is terminated with a NULL pointer.
Compiling with "gcc -O2 -Wall" does not cause any problems, but
compiling with "-O3 -Wall" generates:
$ make CFLAGS='-O3 -Wall' refs.o
refs.c: In function ‘shorten_unambiguous_ref’:
refs.c:3379:29: warning: array subscript is above array bounds [-Warray-bounds]
for (; ref_rev_parse_rules[nr_rules]; nr_rules++)
Curiously, we can silence this by explicitly nr_rules to 0
in the beginning of the loop, even though the compiler
should be able to tell that we follow this code path only
when nr_rules is already 0.

The said function has this signature:
extern int checkout_entry(struct cache_entry *ce,
const struct checkout *state,
char *topath);
At first glance, it might appear that the caller of checkout_entry()
can specify to which path the contents are written out by the last
parameter, and it is tempting to add "const" in front of its type.
In reality, however, topath[] is to point at a buffer to store the
temporary path generated by the callchain originating from this
function, and the temporary path is always short, much shorter than
the buffer prepared by its only caller in builtin/checkout-index.c.
Document the code a bit to clarify so that future callers know how
to use the function better.

The old code does not do boundary check so any paths longer than
PATH_MAX can cause buffer overflow. Replace it with strbuf to handle
paths of arbitrary length.
The OS may reject if the path is too long though. But in that case we
report the cause (e.g. name too long) and usually move on to checking
out the next entry.

Commit 1bbcc224 ("http: refactor options to http_get_*", 28-09-2013)
changed the type of final 'options' argument of the http_get_file()
function from an int to an 'struct http_get_options' pointer.
However, it neglected to update the (single) call site. Since this
call was passing '0' to that argument, it was (correctly) being
interpreted as a null pointer. Change to argument to NULL.
Noticed by sparse. ("Using plain integer as NULL pointer")

git-fast-import documentation says that paths can be C-style quoted.
Unfortunately, the current remote-hg helper doesn't unquote quoted
path and pass them as-is to Mercurial when the commit is created.
This results in the following situation:
- clone a mercurial repository with git
- add a file with space in a directory: `>dir/foo\ bar`
- commit that new file, and push the change to mercurial
- the mercurial repository now has a new directory named '"dir',
which contains a file named 'foo bar"'
Use Python str.decode('string-escape') to unquote the string if it
starts and ends with ". It has been tested with quotes, spaces, and
utf-8 encoded file-names.

In send_pack(), clear the fd passed to pack_objects() by setting
it to -1, since pack_objects() closes the fd (via a call to
run_command()). Likewise, in get_pack(), clear the fd passed to
run_command().
Not doing so risks having git_transport_push(), caller of
send_pack(), closing the fd again, possibly incorrectly closing
some other open file; or similarly with fetch_refs_from_pack(),
indirect caller of get_pack().

This reverts commit ad0e6233320b004f0d686f6887c803e508607bd2.
--valgrind-parallel was broken from the start: during review I made
the whole valgrind setup code conditional on not being a
--valgrind-parallel worker child. But even the children crucially
need $GIT_VALGRIND to be set; it should therefore have been set
outside the conditional.
The fix would be a two-liner, but since the introduction of the
feature, almost four months have passed without anyone noticing that
it is broken. So this feature is not worth the about hundred lines of
test-lib.sh complexity. Revert it.

The gitk manpage suffers from a bit of neglect: there have been only
minor changes, and no changes to the set of options documented, since
a2df1fb (Documentation: New GUI configuration and command-line
options., 2008-11-13). In the meantime, the set of rev-list options
has been expanded several times by options that are useful in gitk,
e.g., --ancestry-path and the optional globbing for --branches, --tags
and --remotes.
Restructure and expand the manpage. List more options that the author
perceives as useful, while remaining somewhat terse. Ideally the user
should not have to look up any of the references, but we dispense with
precise explanations in some places and refer to git-log(1) instead.
Note that the options that have an easy GUI equivalent (e.g.,
--word-diff, -S, --grep) are deliberately not listed even in the cases
where they simply fill in the GUI fields.

When parse_pathspec() is called with no paths, the behavior could be
either return no paths, or return one path that is cwd. Some commands
do the former, some the latter. parse_pathspec() itself does not make
either the default and requires the caller to specify either flag if
it may run into this situation.
I've grep'd through all parse_pathspec() call sites. Some pass
neither, but those are guaranteed never pass empty path to
parse_pathspec(). There are two call sites that may pass empty path
and are fixed with this patch.

The previous code was detecting the presence of "--" by looking only at
argument 1. As a result, "git checkout foo bar --" was interpreted as an
ambiguous file/revision list, and errored out with:
error: pathspec 'foo' did not match any file(s) known to git.
error: pathspec 'bar' did not match any file(s) known to git.
error: pathspec '--' did not match any file(s) known to git.
This patch fixes it by walking through the argument list to find the
"--", and now complains about the number of references given.

The "--" notation disambiguates files and branches, but as a side-effect
of the previous implementation, also disabled the branch auto-creation
when $branch does not exist.
A possible scenario is then:
git checkout $branch
=> fails if $branch is both a ref and a file, and suggests --
git checkout $branch --
=> refuses to create the $branch
This patch allows the second form to create $branch, and since the -- is
provided, it does not look for file named $branch.

When drawing the graph of an octopus merge, we draw a horizontal line
from parents 3 and above into the asterisk representing the commit. The
sections of this line should be colored to match the graph lines coming
in from above.
However, if the commit is not in the left-most column we do not take

these colors. Fix this by adding the appropriate offset to the column

This file isn't really harmful, but isn't useful either, and can create
minor annoyance for the user:
* It's confusing, as the presence of a *.pid file often implies that a
process is currently running. A user running "ls .git/" and finding
this file may incorrectly guess that a "git gc" is currently running.
* Leaving this file means that a "git gc" in an already gc-ed repo is
no-longer a no-op. A user running "git gc" in a set of repositories,
and then synchronizing this set (e.g. rsync -av, unison, ...) will see
all the gc.pid files as changed, which creates useless noise.
This patch unlinks the file after the garbage collection is done, so that
gc.pid is actually present only during execution.
Future versions of Git may want to use the information left in the gc.pid
file (e.g. for policies like "don't attempt to run a gc if one has
already been ran less than X hours ago"). If so, this patch can safely be
reverted. For now, let's not bother the users.
