a3347b988a fmt-merge-message: add empty line between tag and signature verification
When adding the information from a tag, put an empty line between the
message of the tag and the commented-out signature verification
information.

At least for the kernel workflow, I often end up re-formatting the message
that people send me in the tag data. In that situation, putting the tag
message and the tag signature verification back-to-back then means that
normal editor "reflow parapgraph" command will get confused and think that
the signature is a continuation of the last message paragraph.

So I always end up having to first add an empty line, and then go back and
reflow the last paragraph. Let's just do it in git directly.

The extra vertical space also makes the verification visually stand out
more from the user-supplied message, so it looks a bit more readable to me
too, but that may be just an odd personal preference.

e9fc64c60a checkout: no progress messages if !isatty(2).
If stderr isn't a tty, we shouldn't be printing incremental progress
messages.  In particular, this affects 'git checkout -f . >&logfile'
unless you provided -q.  And git-new-workdir has no way to provide -q.

It would probably be better to have progress.c check isatty(2) all the time,
but that wouldn't allow things like 'git push --progress' to force progress
reporting to on, so I won't try to solve the general case right now.

Actual fix suggested by Jeff King.

ec83061156 grep: stop leaking line strings with -f
When reading patterns from a file, we pass the lines as allocated string
buffers to append_grep_pat() and never free them.  That's not a problem
because they are needed until the program ends anyway.

However, now that the function duplicates the pattern string, we can
reuse the strbuf after calling that function.  This simplifies the code
a bit and plugs a minor memory leak.

8338f771fe checkout: do not corrupt HEAD on empty repo
In abe1998 ("git checkout -b: allow switching out of an unborn
branch"), a code-path overly-optimisticly assumed that a
branch-name was specified. This is not always the case, and as
a result a NULL-pointer was attempted printed to .git/HEAD.

This could lead to at least two different failure modes:
 1) vsnprintf formated the NULL-string as something useful (e.g
    "(null)")
 2) vsnprintf crashed

Neither were very convenient for formatting a new HEAD-reference.

To fix this, reintroduce some strictness so we only take this
new codepath if a banch-name was specified.

5d8863954f checkout (detached): truncate list of orphaned commits at the new HEAD

all orphaned commits were listed in a warning:

  Warning: you are leaving 2 commits behind...:

But if the new commit is actually one from this list (6aa1af6 in this

because history beginning at HEAD is not "left behind". This makes it so.

f026c7563a log: respect date_mode_explicit with --format:%gd
When we show a reflog selector (e.g., via "git log -g"), we
perform some DWIM magic: while we normally show the entry's
index (e.g., HEAD@{1}), if the user has given us a date
with "--date", then we show a date-based select (e.g.,
HEAD@{yesterday}).

However, we don't want to trigger this magic if the
alternate date format we got was from the "log.date"
configuration; that is not sufficiently strong context for
us to invoke this particular magic. To fix this, commit
f4ea32f (improve reflog date/number heuristic, 2009-09-24)
introduced a "date_mode_explicit" flag in rev_info. This
flag is set only when we see a "--date" option on the
command line, and we a vanilla date to the reflog code if
the date was not explicit.

Later, commit 8f8f547 (Introduce new pretty formats %g[sdD]
for reflog information, 2009-10-19) added another way to
show selectors, and it did not respect the date_mode_explicit
flag from f4ea32f.

This patch propagates the date_mode_explicit flag to the
pretty-print code, which can then use it to pass the
appropriate date field to the reflog code. This brings the
behavior of "%gd" in line with the other formats, and means
that its output is independent of any user configuration.

391b1f2003 teach send-pack about --[no-]progress
The send_pack function gets a "progress" flag saying "yes,
definitely show progress" or "no, definitely do not show
progress". This gets set properly by transport_push when
send_pack is called directly.

However, when the send-pack command is executed separately
(as it is for the remote-curl helper), there is no way to
tell it "definitely do this". As a result, we do not
properly respect "git push --no-progress" for smart-http
remotes; you will still get progress if stderr is a tty.

This patch teaches send-pack --progress and --no-progress,
and teaches remote-curl to pass the appropriate option to
override send-pack's isatty check. This fixes the
--no-progress case above, and as a bonus, also makes "git
push --progress" work when stderr is not a tty.

8d32e60dbe send-pack: show progress when isatty(2)
The send_pack_args struct has two verbosity flags: "quiet"
and "progress". Originally, if "quiet" was set, we would
tell pack-objects explicitly to be quiet, and if "progress"
was set, we would tell it to show progress. Otherwise, we
told it neither, and it relied on isatty(2) to make the
decision itself.

However, commit 01fdc21 changed the meaning of these
variables. Now both "quiet" and "!progress" instruct us to
tell pack-objects to be quiet (and a non-zero "progress"
means the same as before). This works well for transports
which call send_pack directly, as the transport code copies
transport->progress into send_pack_args->progress, and they
both have the same meaning.

However, the code path of calling "git send-pack" was left
behind. It always sets "progress" to 0, and thus always
tells pack-objects to be quiet.  We can work around this by
checking isatty(2) ourselves in the cmd_send_pack code path,
restoring the original behavior of the send-pack command.

234587fc87 gc: use argv-array for sub-commands
git-gc executes many sub-commands. The argument list for
some of these is constant, but for others we add more
arguments at runtime. The latter is implemented by allocating
a constant extra number of NULLs, and either using a custom
append function, or just referencing unused slots by number.

As of commit 7e52f56, which added two new arguments, it is
possible to exceed the constant number of slots for "repack"
by running "git gc --aggressive", causing "git gc" to die.

This patch converts all of the static argv lists to use
argv-array. In addition to fixing the overflow caused by
7e52f56, it has a few advantages:

  1. We can drop the custom append function (which,
     incidentally, had an off-by-one error exacerbating the
     static limit).

  2. We can drop the ugly magic numbers used when adding
     arguments to "prune".

  3. Adding further arguments will be easier; you can just
     add new "push" calls without worrying about increasing
     any static limits.

The octopus merge strategy used to be fed with redundant commits only to

Since 88a21979c (fetch/pull: recurse into submodules when necessary) all
fetched commits are examined if they contain submodule changes (unless
configuration or command line options inhibit that). If a newly recorded
submodule commit is not present in the submodule, a fetch is run inside
it to download that commit.

Checking new refs was done in an else branch where it wasn't executed for
tags. This normally isn't a problem because tags are only fetched with
the branches they live on, then checking the new commits in the fetched
branches for submodule commits will also process all tags. But when a
specific tag is fetched (or the refspec contains refs/tags/) commits only
reachable by tags won't be searched for submodule commits, which is a bug.

Fix that by moving the code outside the if/else construct to handle new
tags just like any other ref. The performance impact of adding tags that
most of the time lie on a branch which is checked anyway for new submodule
commit should be minimal, as since 6859de4 (fetch: avoid quadratic loop
checking for updated submodules) all ref-tips are collected first and then
fed to a single rev-list.

059a500d25 blame: accept --need-minimal
Between v1.7.1 and v1.7.2, 582aa00bdf switched the default "diff"
invocation not to use XDF_NEED_MINIMAL, but this breaks "git blame"
rather badly.

Allow the command line option to ask for an extra careful matching.

7e52f5660e gc: do not explode objects which will be immediately pruned
When we pack everything into one big pack with "git repack
-Ad", any unreferenced objects in to-be-deleted packs are
exploded into loose objects, with the intent that they will
be examined and possibly cleaned up by the next run of "git
prune".

Since the exploded objects will receive the mtime of the
pack from which they come, if the source pack is old, those
loose objects will end up pruned immediately. In that case,
it is much more efficient to skip the exploding step
entirely for these objects.

This patch teaches pack-objects to receive the expiration
information and avoid writing these objects out. It also
teaches "git gc" to pass the value of gc.pruneexpire to
repack (which in turn learns to pass it along to
pack-objects) so that this optimization happens
automatically during "git gc" and "git gc --auto".

658219f1c7 rev-parse --show-prefix: add in trailing newline
Print out a trailing newline when --show-prefix is run with cwd
at the top level of the tree which results in an empty prefix.
Behavior is now like --show-cdup.

Fixes an expected failure in t1501.

135dadef71 push: error out when the "upstream" semantics does not make sense
The user can say "git push" without specifying any refspec.  When using
the "upstream" semantics via the push.default configuration, the user
wants to update the "upstream" branch of the current branch, which is the
branch at a remote repository the current branch is set to integrate with,
with this command.

However, there are cases that such a "git push" that uses the "upstream"
semantics does not make sense:

 - The current branch does not have branch.$name.remote configured.  By
   definition, "git push" that does not name where to push to will not
   know where to push to.  The user may explicitly say "git push $there",
   but again, by definition, no branch at repository $there is set to
   integrate with the current branch in this case and we wouldn't know
   which remote branch to update.

 - The current branch does have branch.$name.remote configured, but it
   does not specify branch.$name.merge that names what branch at the
   remote this branch integrates with. "git push" knows where to push in
   this case (or the user may explicitly say "git push $remote" to tell us
   where to push), but we do not know which remote branch to update.

 - The current branch does have its remote and upstream branch configured,
   but the user said "git push $there", where $there is not the remote
   named by "branch.$name.remote".  By definition, no branch at repository
   $there is set to integrate with the current branch in this case, and
   this push is not meant to update any branch at the remote repository
   $there.

The first two cases were already checked correctly, but the third case was
not checked and we ended up updating the branch named branch.$name.merge
at repository $there, which was totally bogus.
