a3da882120 pager: do wait_for_pager on signal death
Since ea27a18 (spawn pager via run_command interface), the
original git process actually does git work, and the pager
is a child process (actually, on Windows it has always been
that way, since Windows lacks fork). After spawning the
pager, we register an atexit() handler that waits for the
pager to finish.

Unfortunately, that handler does not always run. In
particular, if git is killed by a signal, then we exit
immediately. The calling shell then thinks that git is done;
however, the pager is still trying to run and impact the
terminal. The result can be seen by running a long git
process with a pager (e.g., "git log -p") and hitting ^C.
Depending on your config, you should see the shell prompt,
but pressing a key causes the pager to do any terminal
de-initialization sequence.

This patch just intercepts any death-dealing signals and
waits for the pager before dying. Under typical less
configuration, that means hitting ^C will cause git to stop
generating output, but the pager will keep running.

57b235a4bc refactor signal handling for cleanup functions
The current code is very inconsistent about which signals
are caught for doing cleanup of temporary files and lock
files. Some callsites checked only SIGINT, while others
checked a variety of death-dealing signals.

This patch factors out those signals to a single function,
and then calls it everywhere. For some sites, that means
this is a simple clean up. For others, it is an improvement
in that they will now properly clean themselves up after a
larger variety of signals.

4a16d07272 chain kill signals for cleanup functions
If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:

  do_cleanup(); /* actual work */
  signal(signo, SIG_DFL); /* restore previous behavior */
  raise(signo); /* deliver signal, killing ourselves */

For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.

This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,
and use sigchain_pop to restore whoever was before you in
the stack.

479b0ae81c diff: refactor tempfile cleanup handling
There are two pieces of code that create tempfiles for diff:
run_external_diff and run_textconv. The former cleans up its
tempfiles in the face of premature death (i.e., by die() or
by signal), but the latter does not. After this patch, they
will both use the same cleanup routines.

To make clear what the change is, let me first explain what
happens now:

  - run_external_diff uses a static global array of 2
    diff_tempfile structs (since it knows it will always
    need exactly 2 tempfiles). It calls prepare_temp_file
    (which doesn't know anything about the global array) on
    each of the structs, creating the tempfiles that need to
    be cleaned up. It then registers atexit and signal
    handlers to look through the global array and remove the
    tempfiles. If it succeeds, it calls the handler manually
    (which marks the tempfile structs as unused).

  - textconv has its own tempfile struct, which it allocates
    using prepare_temp_file and cleans up manually. No
    signal or atexit handlers.

The new code moves the installation of cleanup handlers into
the prepare_temp_file function. Which means that that
function now has to understand that there is static tempfile
storage. So what happens now is:

  - run_external_diff calls prepare_temp_file
  - prepare_temp_file calls claim_diff_tempfile, which
    allocates an unused slot from our global array
  - prepare_temp_file installs (if they have not already
    been installed) atexit and signal handlers for cleanup
  - prepare_temp_file sets up the tempfile as usual
  - prepare_temp_file returns a pointer to the allocated
    tempfile

The advantage being that run_external_diff no longer has to
care about setting up cleanup handlers. Now by virtue of
calling prepare_temp_file, run_textconv gets the same
benefit, as will any future users of prepare_temp_file.

There are also a few side benefits to the specific
implementation:

  - we now install cleanup handlers _before_ allocating the
    tempfile, closing a race which could leave temp cruft

  - when allocating a slot in the global array, we will now
    detect a situation where the old slots were not properly
    vacated (i.e., somebody forgot to call remove upon
    leaving the function). In the old code, such a situation
    would silently overwrite the tempfile names, meaning we
    would forget to clean them up. The new code dies with a
    bug warning.

  - we make sure only to install the signal handler once.
    This isn't a big deal, since we are just overwriting the
    old handler, but will become an issue when a later patch
    converts the code to use sigchain

885c716f0f Rename detection: Avoid repeated filespec population
In diffcore_rename, we assume that the blob contents in the filespec
aren't required anymore after estimate_similarity has been called and thus
we free it. But estimate_similarity might return early when the file sizes
differ too much. In that case, cnt_data is never set and the next call to
estimate_similarity will populate the filespec again, eventually rereading
the same blob over and over again.

To fix that, we first get the blob sizes and only when the blob contents
are actually required, and when cnt_data will be set, the full filespec is
populated, once.

b56c79ccea Makefile: use shell for-loop rather than Make's foreach loop during install
The install target uses a foreach loop to generate a single long shell
command line to handle installation of the built-in git commands.  The
maximum length of the argument list varies by platform, and this use of
foreach quickly grows the length of the argument list.  Current git can
exceed the default maximum argument list length on IRIX 6.5 of 20480
depending on the installation path.

Rather than using make's foreach loop to pre-generate the shell command
line, use a shell for-loop and allow the shell to iterate through each of
the built-in commands.

In 'man 1p trap' there is written:

    "Implementations may permit names with the SIG prefix or ignore case
    in signal names as an extension."

So change the lowercase signals to uppercase, which is POSIX compliant
instead of being an extension.

There wasn't anybody claiming that it doesn't work, but there was a bug
with using a signal with the SIG prefix, which is an extension as well.
So let's play it safe and change it, since it doesn't hurt anyone.

While at it, also convert 8 indentation spaces to 1 tab character.

Update the report format again to save the screen real estates, while
avoiding from enclosing the one-line summary of the commit log inside
double quotes pair, which looks awkward when the message begins or ends
with a double quote.  The old format looked like this:

Simply removing the double quotes were found to be confusing as a message
often begins with a short-word (area of the system) and a colon.

The new format looks like this:

    [master d9a5491] foo:bar

2c2dc7c82c Optimize color_parse_mem
Commit 5ef8d77a implemented color_parse_mem, a function for
parsing colors from a non-NUL-terminated string, by simply
allocating a new NUL-terminated string and calling
color_parse. This had a small but measurable speed impact on
a user format that used the advanced color parsing. E.g.,

  # uses quick parsing
  $ time ./git log --pretty=tformat:'%Credfoo%Creset' >/dev/null
  real    0m0.673s
  user    0m0.652s
  sys     0m0.016s

  # uses color_parse_mem
  $ time ./git log --pretty=tformat:'%C(red)foo%C(reset)' >/dev/null
  real    0m0.692s
  user    0m0.660s
  sys     0m0.032s

This patch implements color_parse_mem as the primary
function, with color_parse as a wrapper for strings. This
gives comparable timings to the first case above.

You can have quite a many reflog entries, but you typically won't recall
which branch you were on after switching branches for more than several
times.

Instead of reading the reflog twice, this reads the branch switching event
and keeps as many entries as the user asked from the latest such entries,
which is the minimum required to be able to switch back to the branch we
were recently on.
