In a corner case of large files whose lines do not match uniquely, the
loop to eliminate a line that matches multiple locations adjacent to a run
of lines that do not uniquely match wasted too much cycles.  Fix this by
giving up early after scanning 100 lines in both direction.

An earlier commit 916d081b (Nicer error messages in case saving an object
to db goes wrong, 2006-11-09) confused EACCES with EPERM, the latter of
which is an unlikely error from mkstemp().
Signed-off-by: NSam Vilain <sam@vilain.net>

This avoids the following misleading error message:

error: unable to create temporary sha1 filename ./objects/15: File exists

mkstemp can fail for many reasons, one of which, ENOENT, can occur if
the directory for the temp file doesn't exist. create_tmpfile tried to
handle this case by always trying to mkdir the directory, even if it
already existed. This caused errno to be clobbered, so one cannot tell
why mkstemp really failed, and it truncated the buffer to just the
directory name, resulting in the strange error message shown above.

Note that in both occasions that I've seen this failure, it has not been
due to a missing directory, or bad permissions, but some other, unknown
mkstemp failure mode that did not occur when I ran git again. This code
could perhaps be made more robust by retrying mkstemp, in case it was a
transient failure.

The original intention of 72909bef (Add diff-option --ext-diff, 2007-06-30)
was to optionally allow the use of external diff viewer in "git log"

The list extra_refs contains tags and the objects referenced by them,
so that they can be handled at the end.  When a tag references a
commit, that commit is added to the list using the same name.

Also, the function handle_tags_and_duplicates() relies on the order
the items were added to extra_refs, so clearly we do not want to
use a sorted list here.

On POSIX, rename() can replace files that are not writable. On Windows,
however, read-only files cannot be replaced without additional efforts:
We have to make the destination writable first.

Since the situations where the destination is read-only are rare, we do not
make the destination writable on every invocation, but only if the first
try to rename a file failed with an "access denied" error.

Originally --with-tree=<tree> was designed for the sole purpose of
checking if a given pathspec makes sense as a parameter to git-commit
using it in conjunction with --error-unmatch.  It had logic to avoid
showing the same entry (one came from the original index, another from the
overlayed tree) twice so that it works with -c (i.e. "show-cached"), but
otherwise it was not designed to work with the flags such as -m, -d, etc.

This teaches the same logic to cover the codepath for -m and -d.

The date/time parsing code was confused if the input time HH:MM:SS is
followed by fractional seconds.  Since we do not record anything finer
grained than seconds, we could just drop fractional part, but there is a
twist.

We have taught people that not just spaces but dot can be used as word
separators when spelling things like:

    $ git log --since 2.days
    $ git show @{12:34:56.7.days.ago}

and we shouldn't mistake "7" in the latter example as a fraction and
discard it.

The rules are:

 - valid days of month/mday are always single or double digits.

 - valid years are either two or four digits

   No, we don't support the year 600 _anyway_, since our encoding is based
   on the UNIX epoch, and the day we worry about the year 10,000 is far
   away and we can raise the limit to five digits when we get closer.

 - Other numbers (eg "600 days ago") can have any number of digits, but
   they cannot start with a zero. Again, the only exception is for
   two-digit numbers, since that is fairly common for dates ("Dec 01" is
   not unheard of)

So that means that any milli- or micro-second would be thrown out just
because the number of digits shows that it cannot be an interesting date.

A milli- or micro-second can obviously be a perfectly fine number
according to the rules above, as long as it doesn't start with a '0'. So
if we have

	12:34:56.123

then that '123' gets parsed as a number, and we remember it. But because
it's bigger than 31, we'll never use it as such _unless_ there is
something after it to trigger that use.

So you can say "12:34:56.123.days.ago", and because of the "days", that
123 will actually be meaninful now.

Previously, when 'repack -a' was called and there were no packs in the local
repository without a .keep file, the repack would fall back to calling
pack-objects with '--unpacked --incremental'. This resulted in the created
pack file, if any, to be missing the packed objects in the alternate object
store. Test that this specific case has been fixed.

Earlier commit 55218834 (checkout: do not lose staged removal, 2008-09-07)
tightened the rule to prevent switching branches from losing local
changes, so that staged removal of paths can be protected, while
attempting to keep a loophole to still allow a special case of switching
out of an un-checked-out state.

However, the loophole was made a bit too tight, and did not allow
switching from one branch (in an un-checked-out state) to check out
another branch.

The change to builtin-checkout.c in this commit loosens it to allow this,
by not insisting the original commit and the new commit to be the same.

It also introduces a new function, is_index_unborn (and an associated
macro, is_cache_unborn), to check if the repository is truly in an
un-checked-out state more reliably, by making sure that $GIT_INDEX_FILE
did not exist when populating the in-core index structure.  A few places
the earlier commit 55218834 added the check for the initial checkout
condition are updated to use this function.
