It happens because the file handle is not properly configured before the subject is read back. This patch fixes it by factoring out the code that is used to setup the output handle into a separate function, and calling it from the reading code.

It requires valgrind 3.4.0 or newer. It works by creating symlinks to a valgrind script, which have the same name as our Git binaries, and then putting that directory in front of the test script's PATH as well as set GIT_EXEC_PATH to that directory. Git scripts are symlinked from that directory directly. That way, Git binaries called by Git scripts are valgrinded, too. Valgrind can be used by specifying "GIT_TEST_OPTS=--valgrind" in the make invocation. Any invocation of git that finds any errors under valgrind will exit with failure code 126. Any valgrind output will go to the usual stderr channel for tests (i.e., /dev/null, unless -v has been specified). If you need to pass options to valgrind -- you might want to run another tool than memcheck, for example -- you can set the environment variable GIT_VALGRIND_OPTIONS. A few default suppressions are included, since libz seems to trigger quite a few false positives. We'll assume that libz works and that we can ignore any errors which are reported there. Note: it is safe to run the valgrind tests in parallel, as the links in t/valgrind/bin/ are created using proper locking. Initial patch and all the hard work by Jeff King.

While it is not strictly necessary to look through the whole PATH to find git binaries to override, it is in line with running an expensive test (which valgrind is) to make extra sure that only binaries are tested that actually come from the git.git checkout. In the same spirit, we can test that neither our test suite nor our scripts try to run the *.sh or *.perl scripts directly.

So introduce the option '--tee' which triggers that the output of the tests will be written to t/test-results/$TEST.out in addition to the terminal, where $TEST is the basename of the script. Unfortunately, there seems to be no way to redirect a given file descriptor to a specified subprocess in POSIX shell, only redirection to a file is supported via 'exec > $FILE'. At least with bash, one might think that 'exec >($COMMAND)' would work as intended, but it does not. The common way to work around the lack of proper tools support is to work with named pipes, alas, one of our most beloved platforms does not really support named pipes. Besides, we would need a pipe for every script, as the whole point of this patch is to allow parallel execution. Therefore, we handle the redirection in the following way: when '--tee' was passed to the test script, the variable GIT_TEST_TEE_STARTED is set (to avoid triggering that code path again) and the script is started _again_, in a subshell, redirected to the command "tee".

If the index update machinery and git diff happen to disagree on whether a particular file is modified, it may cause git-gui to enter an infinite index rescan loop, where an empty diff starts a rescan, which finds the same set of files modified, and tries to display the diff for the first one, which happens to be the empty one. A current example of a possible disagreement point is the autocrlf filter. This patch breaks the loop by using a global counter to track the auto-rescans. The variable is reset whenever a non-empty diff is displayed. Another suggested approach, which is based on giving the --exit-code argument to git diff, cannot be used, because diff-files seems to trust the timestamps in the index, and returns a non-zero code even if the file is actually unchanged, which essentially defeats the purpose of the auto-rescan logic.

And to further optimise we use 'i >= max_len' instead of 'i == max_len', the reason is that it is now the exact opposite of one part inside the while-loop termination expression 'i < max_len && name[i] == cache.path[i]', and then the compiler can probably reuse a test instruction from it.

So if one directory containing 200 files is moved to an other location we get 199 failed calls to rmdir() and 1 successful call. To fix this and avoid some unnecessary calls to rmdir(), we schedule each directory for removal and wait much longer before we do the real call to rmdir(). Since the unlink_entry() function is called with alphabetically sorted names, this new function end up being very effective to avoid unnecessary calls to rmdir(). In some cases over 95% of all calls to rmdir() is removed with this patch.

I think it should be useful to catch these warnings, as I it could be an indication of that the cache would not be very effective if it is doing ping-pong by switching between different cache types too many times. Also, if someone is experimenting with the lstat_cache(), this patch will maybe be useful while debugging. If someone is able to trigger the warning, then send a mail to the GIT mailing list, containing the first 15 lines of the warning, and a short description of the GIT commands to trigger the warnings. I hope someone is willing to use this patch for a while, to be able to catch possible ping-pong's.

Notice the memmove line, where the CPU did 7710 / 277 = 27.8 cycles
per instruction, and compared to the total cycles spent inside the
source code of GIT for this command, all the memmove() calls
translates to (7710 * 100) / 14775 = 52.2% of this.

Retesting with a GIT program compiled for gcov usage, I found out that
the memmove() calls came from remove_index_entry_at() in read-cache.c,
where we have:

        memmove(istate->cache + pos,
                istate->cache + pos + 1,
                (istate->cache_nr - pos) * sizeof(struct cache_entry *));

remove_index_entry_at() is called 4902 times from check_updates() in
unpack-trees.c, and each time called we move each cache_entry pointers
(from the removed one) one step to the left.

Since we have 28828 entries in the cache this time, and if we on
average move half of them each time, we in total move approximately
4902 * 0.5 * 28828 * 4 = 282 629 712 bytes, or twice this amount if
each pointer is 8 bytes (64 bit).

OK, is seems that the function check_updates() is called 28 times, so
the estimated guess above had been more correct if check_updates() had
been called only once, but the point is: we get lots of bytes moved.

To fix this, and use an O(N) algorithm instead, where N is the number
of cache_entries, we delete/remove all entries in one loop through all
entries.

From a retest, the new remove_marked_cache_entries() from the patch
below, ended up with the following output line from oprofile:

46        0.0105  15        0.0041  git                      remove_marked_cache_entries

If we can trust the numbers from oprofile in this case, we saved
approximately ((7710 - 46) * 20000) / (2 * 1000 * 1000 * 1000) = 0.077
seconds CPU time with this fix for this particular test.  And notice
that now the CPU did only 46 / 15 = 3.1 cycles/instruction.

Subject: make USE_NSEC work as expected

Since the filesystem ext4 is now defined as stable in Linux v2.6.28,
and ext4 supports nanonsecond resolution timestamps natively, it is
time to make USE_NSEC work as expected.

This will make racy git situations less likely to happen.  For 'git
checkout' this means it will be less likely that we have to open, read
the contents of the file into RAM, and check if file is really
modified or not.  The result sould be a litle less used CPU time, less
pagefaults and a litle faster program, at least for 'git checkout'.

Since the number of possible racy git situations would increase when
disks gets faster, this patch would be more and more helpfull as times
go by.  For a fast Solid State Disk, this patch should be helpfull.

Note that, when file operations starts to take less than 1 nanosecond,
one would again start to get more racy git situations.

For more info on racy git, see Documentation/technical/racy-git.txt
For more info on ext4, see http://kernelnewbies.org/Ext4

Subject: verify_uptodate(): add ce_uptodate(ce) test

If we inside verify_uptodate() can already tell from the ce entry that
it is already uptodate by testing it with ce_uptodate(ce), there is no
need to call lstat(2) and ie_match_stat() afterwards.

And, reading from the commit log message from:

    commit eadb5831342bb2e756fa05c03642c4aa1929d4f5
    Author: Junio C Hamano 
    Date:   Fri Jan 18 23:45:24 2008 -0800

    Avoid running lstat(2) on the same cache entry.

this also seems to be correct usage of the ce_uptodate() macro
introduced by that patch.

This will avoid lots of lstat(2) calls in some cases, for example
by running the 'git checkout' command.

Subject: format-patch: threading test reactivation

t4014 tests format-patch --thread since 7d812145, but the tests were
ineffective right from the start at least for bash and dash.  The
loops of the form

  for ...; do something || break; done

introduced by 7d812145 and 5d02294 always exit with status 0, even if
'something' failed, because 'break' returns 0 unless there was no loop
to break.

We take a rather different approach that uses an admittedly heinous
inline Perl script to mangle all interesting information into a format
that is invariant between runs.  We can then test the full patch
sequence in one go (with --stdout), doing away with the loop problem.

Subject: Support coverage testing with GCC/gcov

With gcc's --coverage option, we can perform automatic coverage data
collection for the test suite.

Add a new Makefile target 'coverage' that scraps all previous coverage
results, recompiles git with the required compiler/linker flags (in
addition to any flags you specify manually), then runs the test suite
and compiles a report.

The compilation must be done with all optimizations disabled, since
inlined functions (and for line-by-line coverage, also optimized
branches/loops) break coverage tracking.

The tests are run serially (with -j1).  The coverage code should
theoretically allow concurrent access to its data files, but the
author saw random test failures.  Obviously this could be improved.

The report currently consists of a list of functions that were never
executed during the tests, which is written to
'coverage-untested-functions'.  Once this list becomes reasonably
short, we would also want to look at branches that were never taken.

Currently only toplevel *.c files are considered.  It would be nice to
at least include xdiff, but --coverage did not save data to
subdirectories on the system used to write this (gcc 4.3.2).

So far there were no tests checking that log --graph actually works.

Note that the tests strip trailing whitespace, as the current --graph

Subject: Test fsck a bit harder

git-fsck, of all tools, has very few tests.  This adds some more:
* a corrupted object;
* a branch pointing to a non-commit;
* a tag pointing to a nonexistent object;
* and a tag pointing to an object of a type other than what the tag
  itself claims.

Only the first two are caught.  At least the third probably should,
too, but currently slips through.

So far, git-patch-id was untested.  Add some simple checks for output
format and patch (in)equality.

Subject: format-patch: track several references

Currently, format-patch can only track a single reference (the
In-Reply-To:) for each mail.  To ensure proper threading, we should
list all known references for every mail.

Change the rev_info.ref_message_id field to a string_list, so that we
can append references at will, and change the output formatting
routines to print all of them in the References: header.  The last
entry in the list is implicitly assumed to be the In-Reply-To:, which
gives output consistent with RFC 2822:

   The "References:" field will contain the contents of the parent's
   "References:" field (if any) followed by the contents of the
   parent's "Message-ID:" field (if any).

Note that this is just preparatory work; nothing uses it yet, so all
"References:" fields in the output are still only one deep.

Subject: format-patch: thread as reply to cover letter even with in-reply-to

Currently, format-patch --thread --cover-letter --in-reply-to $parent
makes all mails, including the cover letter, a reply to $parent.
However, we would want the reader to consider the cover letter above
all the patches.

This changes the semantics so that only the cover letter is a reply to
$parent, while all the patches are formatted as replies to the cover
letter.

Subject: format-patch: support deep threading

For deep threading mode, i.e., the mode that gives a thread structured
like

  + [PATCH 0/n] Cover letter
   `-+ [PATCH 1/n] First patch
      `-+ [PATCH 2/n] Second patch
         `-+ ...

we currently have to use 'git send-email --thread' (the default).  On
the other hand, format-patch also has a --thread option which gives
shallow mode, i.e.,

  + [PATCH 0/n] Cover letter
  |-+ [PATCH 1/n] First patch
  |-+ [PATCH 2/n] Second patch
  ...

To reduce the confusion resulting from having two indentically named
features in different tools giving different results, let format-patch
take an optional argument '--thread=deep' that gives the same output
as 'send-mail --thread'.  With no argument, or 'shallow', behave as
before.  Also add a configuration variable format.thread with the same
semantics.
