When leaving a detached HEAD, we do a revision walk to make
sure the commit we are leaving isn't being orphaned.
However, this leaves crufty marks in the commit objects
which can confuse later walkers, like the one in
stat_tracking_info.
Let's clean up after ourselves to prevent this conflict.

- The text mentioning git-init-db is dropped. init-db is

When $feature{'pathinfo'} is used, gitweb script sets the base URL to
itself, so that relative links to static files work correctly. It
does it by adding something like below to HTML head:
<base href="http://HOST/gitweb.cgi">
This breaks the "patch" anchor links seen on the commitdiff pages,
because these links, being relative (<a href="#patch1">), are resolved
(computed) relative to the base URL and not relative to current URL,
i.e. as:
http://HOST/gitweb.cgi#patch1
Instead, they should look like this:
35a9811ef9 (patch1)
Add an "-anchor" parameter to href(), and use href(-anchor=>"patch1")
to generate "patch" anchor links, so that the full path is included in
the patch link.
While at it, convert
print "foo";
print "bar";
to
print "foo" .
"bar";

Running checks against working tree (e.g. lstat()) and causing
changes to working tree (e.g. unlink()) while building a virtual
ancestor merge does not make any sense. Avoid doing so.
This is not a real fix; it is another magic band-aid on top of

Use the helper function split from the receiving end of "git push" to
allow the same optimization on the receiving end of "git fetch".

The receiving end of "git push" advertises the objects that the repository
itself does not use, but are at the tips of refs in other repositories
whose object databases are used as alternates for it. This helps it avoid
having to receive (and the pusher having to send) objects that are already
available to the receiving repository via the alternates mechanism.
Tweak the helper function that implements this feature, and move it to
transport.[ch] for future reuse by other programs.
The additional test demonstrates how this optimization is helping "git push",
and "git fetch" is ignorant about it.

Current gcc + glibc with -D_FORTIFY_SOURCE try very aggressively to
protect against a programming style which uses write(...) without
checking the return value for errors. Even the usual hint of casting
to (void) does not suppress the warning.
Sometimes when there is an output error, especially right before exit,
there really is nothing to be done. The obvious solution, adopted in
v1.7.0.3~20^2 (run-command.c: fix build warnings on Ubuntu,
2010-01-30), is to save the return value to a dummy variable:
ssize_t dummy;
dummy = write(...);
But that (1) is ugly and (2) triggers -Wunused-but-set-variable
warnings with gcc-4.6 -Wall, so we are not much better off than when
we started.
Instead, use an "if" statement with an empty body to make the intent
clear.
if (write(...))
; /* yes, yes, there was an error. */

In the spirit of v1.5.0.2~21 (Check for PRIuMAX rather than
NO_C99_FORMAT in fast-import.c, 2007-02-20), use PRIuMAX from
git-compat-util.h on all platforms instead of C99-specific formats
like %zu with dangerous fallbacks to %u or %lu.
So now C99-challenged platforms can build git without provoking
warnings or errors from printf, even if pointers do not have the same
size as an int or long.
The need for a fallback PRIuMAX is detected in git-compat-util.h with
"#ifndef PRIuMAX". So while at it, simplify the Makefile and configure
script by eliminating the NO_C99_FORMAT knob altogether.

Since v1.7.0-rc0~34 (make "mktag" a built-in, 2010-01-22), git mktag
uses the C99-style %td format to print ptrdiff_t values. It falls
back to %d when NO_C99_FORMAT is set, on the assumption that pre-C99
systems probably are using 32-bit pointers.
But many modern systems are 64-bit and
* sometimes one wants to test the NO_C99_FORMAT fallbacks using a
modern development platform;
* some platforms (I'm looking at you, msvc) have not gotten with the
program and are still C89-only.
These ptrdiff_t values are offsets from the beginning of a buffer, so
a size_t or uintmax_t would work about as well. Use the latter so we
can take advantage of the PRIuMAX fallback in git-compat-util.h, even
on C99-challenged systems with 64-bit pointers.

'git stash create' must operate with a temporary index. For this purpose,
it used 'cp -p' to create a copy. -p is needed to preserve the timestamp
of the index file. Now Jakob Pfender reported a certain combination of
a Linux NFS client, OpenBSD NFS server, and cp implementation where this
operation failed.
Luckily, the first operation in git-stash after copying the index is to
call 'git read-tree'. Therefore, use --index-output instead of 'cp -p'
to write the copy of the index.
--index-output requires that the specified file is on the same volume as
the source index, so that the lock file can be rename()d. For this reason,
the name of the temporary index is constructed in a way different from the
other temporary files. The code path of 'stash -p' also needs a temporary
index, but we do not use the new name because it does not depend on the
same precondition as --index-output.

The * was inside the quotes, so that the pattern was never expanded and the
temporary files were never removed. As a consequence, 'stash -p' left a
.git-stash-*-patch file in $GIT_DIR. Other code paths did not leave files
behind because they removed the temporary file themselves, at least in
non-error paths.

Consider the following code fragment:
/*
* test
*/
vim ":set list" mode shows that the first character on each line is a
tab:
^I/*$
^I * test$
^I */$
By default, the "highlight" program will retain the tabs in the HTML
output:
$ highlight --fragment --syntax c test.c
<span class="hl com">/*</span>
<span class="hl com"> * test</span>
<span class="hl com"> */</span>
vim list mode:
^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$
In gitweb, this winds up looking something like:
1 /*
2 * test
3 */
I tried both Firefox and Opera and saw the same behavior.
The desired output is:
1 /*
2 * test
3 */
This can be accomplished by specifying "--replace-tabs=8" on the
highlight command line.

The code notices that the caller does not want any detail of the changes
and only wants to know if there is a change or not by specifying --quiet.
And it breaks out of the loop when it knows it already found any change.
When you have a post-process filter (e.g. --diff-filter), however, the
path we found to be different in the previous round and set HAS_CHANGES
bit may end up being uninteresting, and there may be no output at the end.
The optimization needs to be disabled for such case.
Note that the f245194 (diff: change semantics of "ignore whitespace"
options, 2009-05-22) already disables this optimization by refraining
from setting HAS_CHANGES when post-process filters that need to inspect
the contents of the files (e.g. -S, -w) in diff_change() function.

Some versions of strlen use SSE to speed up the calculation and load 4
bytes at a time, even if it means reading past the end of the
allocated memory. This read is safe and when the strlen function is
inlined, it is not replaced by valgrind, which reports a
false-possitive.
Tell valgrind to ignore this particular error, as the read is, in
fact, safe. Current upstream-released version 3.6.1 is affected. Some
distributions have this fixed in their latest versions.
