pack-objects: free preferred base memory after usage
When adding objects for preferred delta base, the content from tree
objects leading to given paths is kept in a cache. This has the
potential to grow significantly, especially with large directories as
the whole tree object content is loaded in memory, even if in practice
the number of those objects is limited to the 256 cache entries plus the
$window root tree objects. Still, that can't hurt freeing that up after
object enumeration is done, and before more memory is needed for delta
search.

make shallow repository deepening more network efficient
First of all, I can't find any reason why thin pack generation is
explicitly disabled when dealing with a shallow repository. The
possible delta base objects are collected from the edge commits which
are always obtained through history walking with the same shallow refs
as the client, Therefore the client is always going to have those base
objects available. So let's remove that restriction.
Then we can make shallow repository deepening much more efficient by
using the remote's unshallowed commits as edge commits to get preferred
base objects for thin pack generation. On git.git, this makes the data
transfer for the deepening of a shallow repository from depth 1 to depth 2
around 134 KB instead of 3.68 MB.

The current code just leaves the transport in whatever state
it was in after performing the fetch. For a non-empty clone
over the git protocol, the transport code already
disconnects at the end of the fetch.
But for an empty clone, we leave the connection hanging, and
eventually close the socket when clone exits. This causes
the remote upload-pack to complain "the remote end hung up
unexpectedly". While this message is harmless to the clone
itself, it is unnecessarily scary for a user to see and may
pollute git-daemon logs.
This patch just explicitly calls disconnect after we are
done with the remote end, which sends a flush packet to
upload-pack and cleanly disconnects, avoiding the error
message.
Other transports are unaffected or slightly improved:
- for a non-empty repo over the git protocol, the second
disconnect is a no-op (since we are no longer connected)
- for "walker" transports (like HTTP or FTP), we actually
free some used memory (which previously just sat until
the clone process exits)
- for "rsync", disconnect is always a no-op anyway

When resolving a conflicted merge, two lists in the status output need
more attention from the user than other parts.
- the list of updated paths is useful to review the amount of changes the
merge brings in (the user cannot do much about them other than
reviewing, though); and
- the list of unmerged paths needs the most attention from the user; the
user needs to resolve them in order to proceed.
Since the output of git status does not by default go through the pager,
the early parts of the output can scroll away at the top. It is better to
put the more important information near the bottom. During a merge, local
changes that are not in the index are minimum, and you should keep the
untracked list small in any case, so moving the unmerged list from the top
of the output to immediately after the list of updated paths would give us
the optimum layout.

builtin-apply.c: get rid of an unnecessary use of temporary array
Instead of allocating a temporary array imglen[], copying contents to it
from another array img->line[], and then using imglen[], use the value
from img->line[], whose value does not change during the whole process.
This incidentally removes a use of C99 variable length array, which some

Until now, there was no coverage of relative date printing
or approxidate parsing routines (mainly because we had no
way of faking the "now" time for relative date calculations,
which made consistent testing impossible).
This new script tries to exercise the basic features of
show_date and approxidate. Most of the tests are just "this
obvious thing works" to prevent future regressions, with a
few exceptions:
- We confirm the fix in 607a9e8 that relative year/month
dates in the latter half of a year round correctly.
- We confirm that the improvements in b5373e9 and 1bddb25
work.

The test-date program goes back to the early days of git,
where it was presumably used to do manual sanity checks on
changes to the date code. However, it is not actually used
by the test suite to do any sort of automatic of systematic
tests.
This patch refactors the interface to the program to try to
make it more suitable for use by the test suite. There
should be no fallouts to changing the interface since it is
not actually installed and is not internally called by any
other programs.
The changes are:
- add a "mode" parameter so the caller can specify which
operation to test
- add a mode to test relative date output from show_date
- allow faking a fixed time via the TEST_DATE_NOW
environment variable, which allows consistent automated
testing
- drop the use of ctime for showing dates in favor of our
internal iso8601 printing routines. The ctime output is
somewhat redundant (because of the day-of-week) which
makes writing test cases more annoying.

When checkout sees that HEAD points to a non-existent ref,
it currently acts as if "-f" was given; this behavior dates
back to 5a03e7f, which enabled checkout from unborn branches
in the shell version of "git-checkout". The reasoning given
is to avoid the code path which tries to merge the tree
contents. When checkout was converted to C, this code
remained intact.
The unfortunate side effect of this strategy is that the
"force" code path will overwrite working tree and index
state that may be precious to the user. Instead of enabling
"force", this patch uses the normal "merge" codepath for an
unborn branch, but substitutes the empty tree for the "old"
commit.
This means that in the absence of an index, any files in the
working tree will be treated as untracked files, and a
checkout which would overwrite them is aborted. Similarly,
any paths in the index will be merged with an empty entry
as the base, meaning that unless the new branch's content is
identical to what's in the index, there will be a conflict
and the checkout will be aborted.
The user is then free to correct the situation or proceed
with "-f" as appropriate.
This patch also removes the "warning: you are on a branch
yet to be born" message. Its function was to warn the user
that we were enabling the "-f" option. Since we are no
longer doing that, there is no reason for the user to care
whether we are switching away from an unborn branch.

If all refs sent by the remote repo during a fetch are reachable
locally, then no further conversation is performed with the remote. This
check is skipped when the --depth argument is provided to allow the
deepening of a shallow clone which corresponding remote repo has no
changed.
However, some additional filtering was added in commit c29727d5 to
remove those refs which are equal on both sides. If the remote repo has
not changed, then the list of refs to give the remote process becomes
empty and simply attempting to deepen a shallow repo always fails.
Let's stop being smart in that case and simply send the whole list over
when that condition is met. The remote will do the right thing anyways.

Thell Fowler noticed that various "ignore whitespace" options to git diff
do not work well on an incomplete line.
The loop control of the function responsible for these bugs was extremely
difficult to follow. This patch restructures the loops for three variants
of "ignore whitespace" logic.
The basic idea of the re-written logic is:
- A loop runs while the characters from both strings we are looking at
match. We declare unmatch immediately when we find something that does
not match and return false from the function. We break out of the loop
if we ran out of either side of the string.
The way we skip spaces inside this loop varies depending on the style
of ignoring whitespaces.
- After the above loop breaks, we know that the parts of the strings we
inspected so far match, ignoring the whitespaces. The lines can match
only if the remainder consists of nothing but whitespaces. This part
of the logic is shared across all three styles.
The new code is more obvious and should be much easier to follow.

xutils: Fix hashing an incomplete line with whitespaces at the end
Upon seeing a whitespace, xdl_hash_record_with_whitespace() first skipped
the run of whitespaces (excluding LF) that begins there, ensuring that the
pointer points at the last whitespace character in the run, and assumed
that the next character must be LF at the end of the line. This does not
work when hashing an incomplete line, which lacks the LF at the end.
Introduce "at_eol" variable that is true when either we are at the end of
line (looking at LF) or at the end of an incomplete line, and use that
instead throughout the code.
The previous patch to improve approxidate got us to the point that a lot
of the remaining annoyances were due to the 'strict' date handling running
first, and deciding that it got a good enough date that the approximate
date routines were never even invoked.
For example, using a date string like
6AM, June 7, 2009
the strict date logic would be perfectly happy with the "June 7, 2009"
part, and ignore the 6AM part that it didn't understand - resulting in the
information getting dropped on the floor:
6AM, June 7, 2009 -> Sat Jun 6 00:00:00 2009
and the date being calculated as if it was midnight, and the '6AM' having
confused the date routines into thinking about '6 June' rather than 'June
7' at 6AM (ie notice how the _day_ was wrong due to this, not just the
time).
So this makes the strict date routines a bit stricter, and requires that
not just the date, but also the time, has actually been parsed. With that
fix, and trivial extension of the approxidate routines, git now properly
parses the date as
6AM, June 7, 2009 -> Sun Jun 7 06:00:00 2009
without dropping the fuzzy time ("6AM" or "noon" or any of the other
non-strict time formats) on the floor.

This is not a new failure mode - approxidate has always been kind of
random in the input it accepts, but some of the randomness is more
irritating than others.
For example:
Jun 6, 5AM -> Mon Jun 22 05:00:00 2009
5AM Jun 6 -> Sat Jun 6 05:00:00 2009
Whaa? The reason for the above is that approxidate squirrells away the '6'
from "Jun 6" to see if it's going to be a relative number, and then
forgets about it when it sees a new number (the '5' in '5AM'). So the odd
"June 22" date is because today is July 22nd, and if it doesn't have
another day of the month, it will just pick todays mday - having ignored
the '6' entirely due to getting all excited about seeing a new number (5).
There are other oddnesses. This does not fix them all, but I think it
makes for fewer _really_ perplexing cases. At least now we have
Jun 6, 5AM -> Sat Jun 6 05:00:00 2009
5AM, Jun 6 -> Sat Jun 6 05:00:00 2009
which makes me happier. I can still point to cases that don't work as
well, but those are separate issues.
