6ab149ea89 git-quiltimport: preserve standard input to be able to read user input
When run without --author and it fails to determine an author, git
quiltimport tries `read patch_author` to get user input, but standard
input has been redirected to the patch series file.  This commit lets
quiltimport read the series file through file descriptor 3 so that the
standard input is preserved.

10edf37796 never fallback relative times to absolute
Previously, for dates older than 12 months we fell back to just giving the
absolute time.  This can be a bit jarring when reading a list of times.

Instead, let's switch to "Y years, M months" for five years, and then just
"Y years" after that.

No particular reason on the 5 year cutoff except that it seemed reasonable
to me.

afe756c936 send-email: don't create temporary compose file until it is needed
Commit eed6ca7 caused a minor regression when it switched to using
tempfile() to generate the temporary compose file. Since tempfile()
creates the file at the time it generates the filename, zero-length
temporary files are being left behind unless --compose is used (in which
case the file is cleaned up).

This patch fixes the regression by not calling tempfile() to generate
the compose filename unless --compose is in use.

e1afca4fd3 write_index(): update index_state->timestamp after flushing to disk
Since this timestamp is used to check for racy-clean files, it is
important to keep it uptodate.

For the 'git checkout' command without the '-q' option, this make a
huge difference.  Before, each and every file which was updated, was
racy-clean after the call to unpack_trees() and write_index() but
before the GIT process ended.

And because of the call to show_local_changes() in builtin-checkout.c,
we ended up reading those files back into memory, doing a SHA1 to
check if the files was really different from the index.  And, of
course, no file was different.

With this fix, 'git checkout' without the '-q' option should now be
almost as fast as with the '-q' option, but not quite, as we still do
some few lstat(2) calls more without the '-q' option.

Below is some average numbers for 10 checkout's to v2.6.27 and 10 to
v2.6.25 of the Linux kernel, to show the difference:

before (git version 1.6.2.rc1.256.g58a87):
 7.860 user  2.427 sys  19.465 real  52.8% CPU  faults: 0 major 95331 minor

30984ed2e9 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.

2175c10d5a 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

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.

b079c50e03 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.

7dff9b30ea Support 'raw' date format
Talking about --date, one thing I wanted for the 1234567890 date was to
get things in the raw format. Sure, you get them with --pretty=raw, but it
felt a bit sad that you couldn't just ask for the date in raw format.

So here's a throw-away patch (meaning: I won't be re-sending it, because I
really don't think it's a big deal) to add "--date=raw". It just prints
out the internal raw git format - seconds since epoch plus timezone (put
another way: 'date +"%s %z"' format)

901c369af5 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).

7d233dea5f gitweb: Hyperlink multiple git hashes on the same commit message line
The current implementation only hyperlinks the first hash on
a given line of the commit message.  It seems sensible to
highlight all of them if there are multiple, and it seems
plausible that there would be multiple even with a tidy line
length limit, because they can be abbreviated as short as 8
characters.

Benchmark:

I wanted to make sure that using the 'e' switch to the Perl regex
wasn't going to kill performance, since this is called once per commit
message line displayed.

In all three A/B scenarios I tried, the A and B yielded the same
results within 2%, where A is the version of code before this patch
and B is the version after.

1: View a commit message containing the last 1000 commit hashes
2: View a commit message containing 1000 lines of 40 dots to avoid
   hyperlinking at the same message length
3: View a short merge commit message with a few lines of text and
   no hashes

All were run in CGI mode on my sub-production hardware on a recent
clone of git.git.  Numbers are the average of 10 reqests per second
with the first request discarded, since I expect this change to affect
primarily CPU usage.  Measured with ApacheBench.

Note that the web page rendered was the same; while the new code
supports multiple hashes per line, there was at most one per line.

The primary purpose of scenarios 2 and 3 were to verify that the
addition of 1000 commit messages had an impact on how much of the time
was spent rendering commit messages.  They were all within 2% of 0.80
requests per second (much faster).

So I think the patch has no noticeable effect on performance.

024aa7d8d5 system_path(): simplify using strip_path_suffix(), and add suffix "git"
At least for the author of this patch, the logic in system_path() was
too hard to understand.  Using the function strip_path_suffix() documents
the idea of the code better.

The real change is to add the suffix "git", so that a runtime prefix will
be computed correctly even when the executable was called in /git/ as is
the case in msysGit (Windows insists to search the current directory
before the PATH when looking for an executable).

4fcc86b07d Introduce the function strip_path_suffix()
The function strip_path_suffix() will try to strip a given suffix from
a given path.  The suffix must start at a directory boundary (i.e. "core"
is not a path suffix of "libexec/git-core", but "git-core" is).

Arbitrary runs of directory separators ("slashes") are assumed identical.

Example:

	strip_path_suffix("C:\\msysgit/\\libexec\\git-core",
		"libexec///git-core", &prefix)

will set prefix to "C:\\msysgit" and return 0.

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.

1dcafcc0e6 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 eadb583134
    Author: Junio C Hamano <gitster@pobox.com>
    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.

fba2f38a2c 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.

8cd6192e16 fix compile error when USE_NSEC is defined
'struct cache' does not have a 'usec' member, but a 'unsigned int
nsec' member.  Simmilar 'struct stat' does not have a 'st_mtim.usec'
member, and we should instead use 'st_mtim.tv_nsec'.
