Move almost all code out of the child_handler() into check_dead_children().
The fact that systemcalls get interrupted by signals allows us to
make the SIGCHLD signal handler almost a no-op by simply running
check_dead_children() right before waiting on poll().
In case some systems do not interrupt systemcalls upon signal receipt,
all zombies will eventually be collected before the next poll() cycle.

submodule foreach <command-list> will execute the list of commands in
each currently checked out submodule directory. The list of commands
is arbitrary as long as it is acceptable to sh. The variables '$path'
and '$sha1' are availble to the command-list, defining the submodule
path relative to the superproject and the submodules's commitID as
recorded in the superproject (this may be different than HEAD in the
submodule).
This utility is inspired by a number of threads on the mailing list
looking for ways to better integrate submodules in a tree and work
with them as a unit. This could include fetching a new branch in each
from a given source, or possibly checking out a given named branch in
each. Currently, there is no consensus as to what additional commands
should be implemented in the porcelain, requiring all users whose needs
exceed that of git-submodule to do their own scripting. The foreach
command is intended to support such scripting, and in particular does
no error checking and produces no output, thus allowing end users
complete control over any information printed out and over what
constitutes an error. The processing does terminate if the command-list
returns an error, but processing can easily be forced for all
submodules be terminating the list with ';true'.

Many test scripts assumed that they will start in a 'trash' subdirectory
that is a single level down from the t/ directory, and referred to their
test vector files by asking for files like "../t9999/expect". This will
break if we move the 'trash' subdirectory elsewhere.
To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can
refer to t/ directory reliably. This finally makes all the tests use
it to refer to the outside environment.
With this patch, and a one-liner not included here (because it would
contradict with what Dscho really wants to do):

"git stash -h" showed some incomplete and ugly usage information.
For example, the useful "--keep-index" option for "save" or the "--index"
option for "apply" were not shown. Also in the documentation synopsis they
were not shown, so that there is no incentive to scroll down and even see
that such options exist.
This patch improves the git-stash synopsis in the documentation by
mentioning that further options to the stash commands and then copies
this synopsis to the usage information string of git-stash.sh.
For the latter, the dashless git command string has to be inserted on the
second and the following usage lines. The code of this is taken from
git-sh-setup so that all lines will show the command string.
Note that the "create" command is not advertised at all now, because
it was not mentioned in git-stash.txt.

This further enhances xdi_diff_outf() interface so that it takes two
common parameters: the callback function that processes one line at a
time, and a pointer to its application specific callback data structure.
xdi_diff_outf() creates its own "xdiff_emit_state" structure and stashes
these two away inside it, which is used by the lowest level output
function in the xdiff_outf() callchain, consume_one(), to call back to the
application layer. With this restructuring, we lift the requirement that
the caller supplied callback data structure embeds xdiff_emit_state
structure as its first member.

test-chmtime can adjust the mtime of a file based on the file's mtime, or
based on the system time. For files accessed over NFS, the file's mtime is
set by the NFS server, and as such may vary a great deal from the NFS
client's system time if the clocks of the client and server are out of
sync. Since these tests are testing the expire feature of git-prune, an
incorrect mtime could cause a file to be expired or not expired incorrectly
and produce a test failure.
Avoid this NFS pitfall by modifying the calls to test-chmtime so that the
mtime is adjusted based on the system time, rather than the file's mtime.

* git://git.bogomips.org/git-svn:
git-svn: Reduce temp file usage when dealing with non-links
git-svn: Make it incrementally faster by minimizing temp files
Git.pm: Add faculties to allow temp files to be cached
Currently, in sub 'close_file', git-svn creates a temporary file and
copies the contents of the blob to be written into it. This is useful
for symlinks because svn stores symlinks in the form:
link $FILE_PATH
Git creates a blob only out of '$FILE_PATH' and uses file mode to
indicate that the blob should be interpreted as a symlink.
As git-hash-object is invoked with --stdin-paths, a duplicate of the
link from svn must be created that leaves off the first five bytes,
i.e. 'link '. However, this is wholly unnecessary for normal blobs,
though, as we already have a temp file with their contents. Copying
the entire file gains nothing, and effectively requires a file to be
written twice before making it into the object db.
This patch corrects that issue, holding onto the substr-like
duplication for symlinks, but skipping it altogether for normal blobs
by reusing the existing temp file.
Signed-off-by: Marcus Griep <marcus@griep.us>
Acked-by: Eric Wong <normalperson@yhbt.net>
Currently, git-svn would create a temp file on four occasions:
1. Reading a blob out of the object db
2. Creating a delta from svn
3. Hashing and writing a blob into the object db
4. Reading a blob out of the object db (in another place in code)
Any time git-svn did the above, it would dutifully create and then
delete said temp file. Unfortunately, this means that between 2-4
temporary files are created/deleted per file 'add/modify'-ed in
svn (O(n)). This causes significant overhead and helps the inode
counter to spin beautifully.
By its nature, git-svn is a serial beast. Thus, reusing a temp file
does not pose significant problems. "truncate and seek" takes much
less time than "unlink and create". This patch centralizes the
tempfile creation and holds onto the tempfile until they are deleted
on exit. This significantly reduces file overhead, now requiring
at most three (3) temp files per run (O(1)).
