0da8b2e7c8 http.c: Don't store destination name in request structures
The destination name within the object store is easily computed
on demand, reusing a static buffer held by sha1_file.c.  We don't
need to copy the entire path into the request structure for safe
keeping, when it can be easily reformatted after the download has
been completed.

This reduces the size of the per-request structure, and removes
yet another PATH_MAX based limit.

The test preq->packfile != NULL is always true.  If packfile was
actually NULL when entering this function the ftell() above would
crash out with a SIGSEGV, resulting in never reaching this point.

Always remove the struct packed_git from the active list, even
if the rename of the temporary file fails.

While we are here, simplify the code a bit by using a common

03b6aeb274 http.c: Remove bad free of static block
The filename variable here is pointing to a block of memory that
was allocated by sha1_file.c and is also held in a static variable
scoped within the sha1_pack_name() function.  Doing a free() here is
returning that memory to the allocator while we might still try to
reuse it on a subsequent sha1_pack_name() invocation.  That's not
acceptable, so don't free it.

8de096b671 gitweb: simplify gitweb.min.* generation and clean-up rules
GITWEB_CSS and GITWEB_JS are meant to be "what URI should the installed
cgi script use to refer to the stylesheet and JavaScript", never "this
is the name of the file we are building".  Don't use them to decide what
file to build minified versions in.

While we are at it, lose FILES that is used only for "clean" target in a
misguided way.  "make clean" should try to remove all the potential
build artifacts regardless of a minor configuration change. Instead of
trying to remove only the build product "make clean" would have created
if it were run without "clean", explicitly list the three potential build
products for removal.

c308b9c25d documentation: clarify direction of core.autocrlf
The description for core.autocrlf refers to reads from / writes to
"the filesystem", the only use of this rather ambiguous term, which
technically could be referring to the git object database. (All other
mentions are part of phrases such as "..filesystems (like NFS)..").

Other sections, including the section on core.safecrlf, use the term
"work tree" for the same purpose as the term "the filesystem" is used in
the core.autocrlf section, so that seems like a good alternative, which
makes it clearer what direction the addition/removal of CR characters
occurs in.

0974c117ff diff: use large integers for diffstat calculations
The diffstat "added" and "changed" fields generally store
line counts; however, for binary files, they store file
sizes. Since we store and print these values as ints, a
diffstat on a file larger than 2G can show a negative size.
Instead, let's use uintmax_t, which should be at least 64
bits on modern platforms.

2179870803 combined diff: correctly handle truncated file
Consider an evil merge of two commits A and B, both of which have a
file 'foo', but the merge result does not have that file.

The combined-diff code learned in 4462731 (combine-diff: do not punt
on removed or added files., 2006-02-06) to concisely show only the
removal, since that is the evil part and the previous contents are
presumably uninteresting.

However, to diagnose an empty merge result, it overloaded the variable
that holds the file's length.  This means that the check also triggers
for truncated files.  Consequently, such files were not shown in the
diff at all despite the merge being clearly evil.

Fix this by adding a new variable that distinguishes whether the file
was deleted (which is the case 4462731 handled) or truncated.  In the
truncated case, we show the full combined diff again, which is rather
spammy but at least does not hide the evilness.

fff0d0abdd Document new "already-merged" rule for branch -d
v1.7.0-rc0~18^2 (branch -d: base the "already-merged" safety on the
branch it merges with, 2009-12-29) taught ‘git branch’ a new heuristic
for when it is safe to delete a branch without forcing the issue.  It
is safe to delete a branch "topic" without second thought if:

 - the branch "topic" is set up to pull from a (remote-tracking,
   usually) branch and is fully merged in that "upstream" branch, or

 - there is no branch.topic.merge configuration and branch "topic" is
   fully merged in the current HEAD.

Update the man page to acknowledge the new rules.

fdf1bc48ca t7006: guard cleanup with test_expect_success
Most of these tests are removing files, environment variables, and
configuration that might interfere outside the test.  Putting these
clean-up commands in the test (in the same spirit as v1.7.1-rc0~59,
2010-03-20) means that errors during setup will be caught quickly and
non-error text will be suppressed without -v.

While at it, apply some other minor fixes:

 - do not rely on the shell to export variables defined with the same
   command as a function call

 - avoid whitespace immediately after the > redirection operator, for
   consistency with the style of other tests

0ba17dd022 am -3: recover the diagnostic messages for corrupt patches
"git am -3" first tries to apply the patch without any extra trick, and
applies it to a synthesized tree for 3-way merge after the first attempt
fails.  "git apply" exits with status 1 for a patch that is well-formed
but is not applicable (and it dies on other errors with non-zereo, non-1
status) and has an optimization to fall back to the 3-way merge only in
the case.

An earlier patch 3ddd170 (am: suppress apply errors when using 3-way,
2009-06-16) squelched diagnostic messages from the first attempt, not to
be shown to the end user.  This worked reasonably well if the reason the
first application failed was because the patch was made against a wrong
version.

When the patch is corrupt (e.g. line-wrapped or leading whitespaces got
dropped), however, because the second patch application is not even
attempted, the error message from the first application is never shown
and is forever lost.  This message is necessary to locate where the patch
is corrupt and fix it up.

We could fix this issue by reverting 3dd170, or keeping the error message
to somewhere and showing it, but because this is an error codepath, the
easiest is to disable the optimization.  The second patch application is
attempted even when the input is corrupt, and it will notice, diagnose,
and stop with an error message.

882749a04f diff: add --word-diff option that generalizes --color-words
This teaches the --color-words engine a more general interface that
supports two new modes:

* --word-diff=plain, inspired by the 'wdiff' utility (most similar to
  'wdiff -n <old> <new>'): uses delimiters [-removed-] and {+added+}

* --word-diff=porcelain, which generates an ad-hoc machine readable
  format:
  - each diff unit is prefixed by [-+ ] and terminated by newline as
    in unified diff
  - newlines in the input are output as a line consisting only of a
    tilde '~'

Both of these formats still support color if it is enabled, using it
to highlight the differences.  --color-words becomes a synonym for
--word-diff=color, which is the color-only format.  Also adds some
compatibility/convenience options.

Thanks to Junio C Hamano and Miles Bader for good ideas.

03e8b541b3 describe: Break annotated tag ties by tagger date
If more than one annotated tag points at the same commit, use the
tag whose tagger field has a more recent date stamp.  This resolves
non-deterministic cases where the maintainer has done:

  $ git tag -a -m "2.1-rc1" v2.1-rc1  deadbeef
  $ git tag -a -m "2.1"     v2.1      deadbeef

If the tag is an older-style annotated tag with no tagger date, we
assume a date stamp at the UNIX epoch. This will cause us to prefer
an annotated tag that has a valid date.

We could also try to consider the tag object chain, favoring a tag
that "includes" another one:

  $ git tag -a -m "2.1-rc0" v2.1-rc1  deadbeef
  $ git tag -a -m "2.1"     v2.1      v2.1-rc1

However traversing the tag's object chain looking for inclusion
is much more complicated.  Its already very likely that even in
these cases the v2.1 tag will have a more recent tagger date than
v2.1-rc1, so with this change describe should still resolve this
by selecting the more recent v2.1.

attribute set by the macro should override an already set
attribute. Consider the following .gitattributes file:

[attr]mybinary	binary -ident
*		ident
foo.bin		mybinary
bar.bin		mybinary ident

Without this patch both foo.bin and bar.bin will have
the ident attribute set, which is probably not what
the user expects. With this patch foo.bin will have an
unset ident attribute, while bar.bin will have it set.

969f9d7322 attr: Allow multiple changes to an attribute on the same line.
When using macros it isn't inconceivable to have an attribute
being set by a macro, and then being reset explicitly.

426c27b7c0 attr: Fixed debug output for macro expansion.
When debug_set() was called during macro expansion, it
received a pointer to a struct git_attr rather than a
string.
