We also move the assignment of -1 to the lock file descriptor
up, so that rollback_lock_file() can be called safely after a
possible attempt to fclose(). This matches the contents of
the 'if' statement just above testing success of fdopen().

Instead of calling close_lock_file() and commit_lock_file() directly,
which take a struct lock_file argument, add two new functions:
close_ref() and commit_ref(), which handle calling the previous
lock_file functions and modifying the ref_lock structure.

The lockfile API is a handy way to obtain a file that is cleaned
up if you die().  But sometimes you would need this sequence to
work:

 1. hold_lock_file_for_update() to get a file descriptor for
    writing;

 2. write the contents out, without being able to decide if the
    results should be committed or rolled back;

 3. do something else that makes the decision --- and this
    "something else" needs the lockfile not to have an open file
    descriptor for writing (e.g. Windows do not want a open file
    to be renamed);

 4. call commit_lock_file() or rollback_lock_file() as
    appropriately.

This adds close_lock_file() you can call between step 2 and 3 in
the above sequence.

This makes write_ref_sha1() more careful: it actually checks the SHA1 of
the ref it is updating, and refuses to update a ref with an object that it
cannot find.

Perhaps more importantly, it also refuses to update a branch head with a
non-commit object. I don't quite know *how* the stable series maintainers
were able to corrupt their repository to have a HEAD that pointed to a tag
rather than a commit object, but they did. Which results in a totally
broken repository that cannot be cloned or committed on.

So make it harder for people to shoot themselves in the foot like that.

The test t1400-update-ref.sh is fixed at the same time, as it
assumed that the commands involved in the particular test would
not care about corrupted repositories whose refs point at
nonexistant bogus objects.  That assumption does not hold true
anymore.

There are two heuristics in Git to detect whether a file is binary
or text. One in xdiff-interface.c (which is taken from GNU diff)
relies on existence of the NUL byte at the beginning. However,
convert.c used a different heuristic, which relied on the percent
of non-printable symbols (less than 1% for text files).

Due to differences in detection whether a file is binary or not,
it was possible that a file that diff treats as binary could be
treated as text by CRLF conversion. This is very confusing for a
user who sees that 'git diff' shows the file as binary expects it
to be added as binary.

This patch makes is_binary to consider any file that contains at
least one NUL character as binary, to ensure that the heuristics
used for CRLF conversion is tighter than what is used by diff.

The codepath to prepare index files for the temporary and next
index file was closing file descriptor it obtained from the
lockfile API by hand, without letting the API know that the fd
should not be doubly closed.

This is not usually a problem (except it may get EBADFD) but if
we opened another fd for an entirely unrelated purpose (say, an
fd used to mmap a packfile) between the time we close the fd to
the index file and the time we commit or rollback the lockfile
(causing it to also try closing the recorded fd), the lockfile
API will close an incorrect file descriptor that is still used
for an entirely unrelated purpose.

There's four close(fd) calls in prepare_index() and they're all
incorrect.  The open fd's are cleaned up in rollback_index_files() and
shouldn't be closed manually.  The patch below gets rid of the extra
close() calls and should fix the problem.

rerere.enabled is _not_ on by default.  The command is enabled if rr-cache
exists even when rerere.enabled is missing, and enabled or disabled by
explicitly setting the rerere.enabled variable.

This reverts commit 16335fdd.

We are calling overlay_tree_on_cache() which does use CE_UPDATE
flag to mark duplicated entries, which is the same as the
codepath in git-ls-files with its --with-tree option.

Because the pathname ce->name is given to path_list_insert()
which does not allow duplicates, there is no breakage either way
from the correctness point of view in this codepath, unlike the
one in ls-files.  But avoiding unnecessary processing with a
single bit check is certainly better.

This hook thought to have found a conflict marker any time it saw
a 7-character combination of any of the characters '<>=' at the
beginning of a line, whereas it should only look for the *same*
character to appear repeatedly.

Also, restrict it to match exactly 7 times, to avoid matching the
underlining with '='-characters often used in documentation.

When running "git commit paths" to create a partial commit, we
used to carefully build the temporary index so that we do not
lose the cached stat information.  The rewrite of the command in
C lost it by carelessly using read_tree().

This resurrects the earlier behaviour to keep the cached stat
information as much as possible by using one-tree merge logic.

The "seen" variable is used by match_pathspec, and must have
as many elements as there are in the given pathspec. We
create the pathspec either from the command line arguments
_or_ from just the current prefix.

Thus allocating "seen" based upon just argc is wrong, since
if argc == 0, then we still have one pathspec, the prefix,
but we don't allocate any space in "seen".

Repositories generated by svnsync cannot be relied on to have
properly set revprops without newlines in UUIDs and URLs.  There
may be broken versions of svnsync out there that append extra
newlines to UUIDs, or the revprops could've been changed by
repository administrators at any time, too.

At least one repository we've come across has an embedded
newline erroneously set in the svnsync-uuid prop.  This is bad
because the trailing newline is taken as another record by the
Git.pm library, and the wantarray detection causes tmp_config()
to return an array with an empty-but-existing second element.

We will now strip leading and trailing whitespace both before
setting and after reading the uuid and url for svnsync values.
We will also force tmp_config to return a single scalar when
reading existing values.

SVN UUIDs should never have whitespace in them, and SVN
repository URLs should be URI-escaped, so neither of those
values we ever see in git-svn should actually have whitespace
in them.

Thanks to Dennis Schridde for the bug report and Junio for
helping diagnose this.
