When unpack_trees() three-way merge logic is called from merge-recursive
and finds that local changes are going to be clobbered, its plumbing level
messages were given as errors first, and then the merge driver added even
more scary message "fatal: merging of trees <a long object name> and
<another long object name> failed".
This is most often encountered by new CVS/SVN migrants who are used to
start a merge from a dirty work tree. The saddest part is that the merge
refused to run to prevent _any_ damage from being done to your work tree
when these messages are given, but the messages look a lot more scarier
than the conflicted case where the user needs to resolve them.
Replace the plumbing level messages so that they talk about what it is
protecting the user from, and end the messages with "Aborting." so that it
becomes clear that the command did not do any harm.
The final "merging of trees failed" message is superfluous, unless you are
interested in debugging the merge-recursive itself. Squelch the current
die() message by default, but allow it to help people who debug git with
verbosity level 4 or greater.
Unless there is some bug, an inner merge that does not touch working tree
should not trigger any such error, so emit the current die() message when
we see an error return from it while running the inner merge, too. It
would also help people who debug git.
We could later add instructions on how to recover (i.e. "stash changes
away or commit on a side branch and retry") instead of the silent
exit(128) I have in this patch, and then use Peff's advice.* mechanism to
squelch it (e.g. "advice.mergeindirtytree"), but they are separate topics.

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.

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.

With the earlier DWIM patches, certain combination of options defaulted
to the "save" command correctly while certain equally valid combination
did not. For example, "git stash -k" were Ok but "git stash -q -k" did
not work.
This makes the logic of defaulting to "save" much simpler. If there are no
non-flag arguments, it is clear that there is no command word, and we
default to "save" subcommand. This rule prevents "git stash -q apply"
from quietly creating a stash with "apply" as the message.
This also teaches "git stash save" to reject an unknown option. This is
to keep a mistyped "git stash save --quite" from creating a stash with a
message "--quite", and this safety is more important with the new logic
to default to "save" with any option-looking argument without an explicit
comand word.

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.
- A few tests are marked to expect failure, which are
regressions recently introduced by the two commits

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.

A request to clone the repository does not give any "have" but asks for
all the refs we offer with "want". When a request does not ask to clone
the repository fully, but asks to fetch some refs into an empty
repository, it will not give any "have" but its "want" won't ask for all
the refs we offer.
If we suppose (and I would say this is a rather big if) that it makes
sense to distinguish these two cases, a hook cannot reliably do this
alone. The hook can detect lack of "have" and bunch of "want", but there
is no direct way to tell if the other end asked for all refs we offered,
or merely most of them.
Between the time we talked with the other end and the time the hook got
called, we may have acquired more refs or lost some refs in the repository
by concurrent operations. Given that we plan to introduce selective
advertisement of refs with a protocol extension, it would become even more
difficult for hooks to guess between these two cases.
This adds "kind [clone|fetch]" to hook's input, as a stable interface to
allow the hooks to tell these cases apart.

resulting pack. Can occur one or more times in the input.
have SHA-1::
40-byte hexadecimal object name the client asked to exclude from
the resulting pack, claiming to have them already. Can occur zero
