cf10f9fdd5 builtin-commit: use reduce_heads() only when appropriate
Since commit 6bb6b034 (builtin-commit: use commit_tree(), 2008-09-10),
builtin-commit performs a reduce_heads() unconditionally.  However,
it's not always needed, and in some cases even harmful.

reduce_heads() is not needed for the initial commit or for an
"ordinary" commit, because they don't have any or have only one
parent, respectively.

reduce_heads() must be avoided when 'git commit' is run after a 'git
merge --no-ff --no-commit', otherwise it will turn the
non-fast-forward merge into fast-forward.  For the same reason,
reduce_heads() must be avoided when amending such a merge commit.

To resolve this issue, 'git merge' will write info about whether
fast-forward is allowed or not to $GIT_DIR/MERGE_MODE.  Based on this
info, 'git commit' will only perform reduce_heads() when it's
committing a merge and fast-forward is enabled.

Also add test cases to ensure that non-fast-forward merges are
committed and amended properly.

0e214af9c3 Makefile: do not set NEEDS_LIBICONV for Solaris 8
This breaks my build on Solaris 8, as there is no separate
libiconv.

The history of this line is somewhat convoluted. In 2fd955c
(in November 2005), NEEDS_LIBICONV was turned on for all
Solaris builds, claiming to "fix an error in Solaris 10 by
setting NEEDS_LIBICONV".

Later, e15f545 (in February of 2006) claimed that "Solaris
9+ don't need iconv", and moved NEEDS_LIBICONV into a
section for Solaris 8.

Furthermore, Brandon Casey claims in

<5A1KxlhmUIHe8iXPxnXYuNXsq0Yjlbwkz2eBin3z7ELuL9nK-4tSpw@cipher.nrlssc.navy.mil>

that he does not set NEEDS_LIBICONV for Solaris 7.

So either one of those commits is totally wrong, or there is
some other magic going on where some Solaris installs need
it and others don't.

Given Brandon's statement and my problems on Solaris 8 with
NEEDS_LIBICONV, I am inclined to think the first commit was
bogus, and that NEEDS_LIBICONV shouldn't be set for Solaris
at all by default. If somebody wants to use iconv and has
installed it manually, they can set it in their config.mak.

aed93de428 gitweb: Support for tag clouds
The "Content tags" (nothing to do with usual Git tags!) are free-form
strings that are attached to random projects and displayed in the
well-known Web2.0-ish tag cloud above project list.

The feature will make use of HTML::TagCloud if available, but will
still display (less pretty) list of tags in case the module is not
installed.

The tagging itself is not done by gitweb - user-provided external
helper CGI needs to be provided; one example is the tagproj.cgi
of Girocco. This functionality might get integrated to gitweb
in the future.

The tags are stored one-per-file in ctags/ subdirectory. The reason
they are not stored in the project config file is that you usually
want to give anyone (even CGI scripts) permission to create new tags
and they are non-essential information, and thus you would make
the ctags/ subdirectory world-writable.

a5a5a04863 xdiff-interface.c: strip newline (and cr) from line before pattern matching
POSIX doth sayeth:

   "In the regular expression processing described in IEEE Std 1003.1-2001,
    the <newline> is regarded as an ordinary character and both a period and
    a non-matching list can match one. ... Those utilities (like grep) that
    do not allow <newline>s to match are responsible for eliminating any
    <newline> from strings before matching against the RE."

Thus far git has not been removing the trailing newline from strings matched
against regular expression patterns. This has the effect that (quoting
Jonathan del Strother) "... a line containing just 'FUNCNAME' (terminated by
a newline) will be matched by the pattern '^(FUNCNAME.$)' but not
'^(FUNCNAME$)'", and more simply not '^FUNCNAME$'.

9126f0091f fix openssl headers conflicting with custom SHA1 implementations
On ARM I have the following compilation errors:

    CC fast-import.o
In file included from cache.h:8,
                 from builtin.h:6,
                 from fast-import.c:142:
arm/sha1.h:14: error: conflicting types for 'SHA_CTX'

/usr/include/openssl/sha.h:117: error: previous declaration of 'SHA1_Final' was here
make: *** [fast-import.o] Error 1

This is because openssl header files are always included in
git-compat-util.h since commit 684ec6c63c whenever NO_OPENSSL is not
set, which somehow brings in <openssl/sha1.h> clashing with the custom
ARM version.  Compilation of git is probably broken on PPC too for the
same reason.

Turns out that the only file requiring openssl/ssl.h and openssl/err.h
is imap-send.c.  But only moving those problematic includes there
doesn't solve the issue as it also includes cache.h which brings in the
conflicting local SHA1 header file.

As suggested by Jeff King, the best solution is to rename our references
to SHA1 functions and structure to something git specific, and define those
according to the implementation used.

2d7a3532c7 gitweb: Fix two 'uninitialized value' warnings in git_tree()
If we did try to access nonexistent directory or file, which means
that git_get_hash_by_path() returns `undef`, uninitialized $hash
variable was passed to 'open' call.  Now we fail early with "404 Not
Found - No such tree" error.  (If we try to access something which
does not resolve to tree-ish, for example a file / 'blob' object, the
error will be caught later, as "404 Not Found - Reading tree failed"
error).

If we tried to use 'tree' action without $file_name ('f' parameter)
set, which means either tree given by hash or a top tree (and we
currently cannot distinguish between those two cases), we cannot print
path breadcrumbs with git_print_page_path().  Fix this by moving call
to git_print_page_path() inside conditional.

c85db254d9 reformat informational commit message
When committing, we print a message like:

  Created [DETACHED commit] <hash> (<subject>) on <branch>

The most useful bit of information there (besides the
detached status, if it is present) is which branch you made
the commit on. However,  it is sometimes hard to see because
the subject dominates the line.

Instead, let's put the most useful information (detached
status and commit branch) on the far left, with the subject
(which is least likely to be interesting) on the far right.

We'll use brackets to offset the branch name so the line is
not mistaken for an error line of the form "program: some
sort of error". E.g.,:

  [jk/bikeshed] created bd8098f: "reformat informational commit message"

shown before the list size cut-off (15) kicks in.

s/noheader/no_header was just to make it obvious what the parameter
affects, so all the code can be found with one grep.

that refactors the sorting logic so that it is not tied to printing

5d6b3a9ef8 Documentation: remove '\' in front of short options
... because they show up in the man and html outputs.

This escaping is only needed for double dashes to be compatible with
older asciidoc versions;  see commit e1ccf53 ([PATCH] Escape asciidoc's
built-in em-dash replacement, 2005-09-12).

f8cca019b9 rebase: Support preserving merges in non-interactive mode
As a result of implementation details, 'git rebase' could
previously only preserve merges in interactive mode. That
limitation was hard for users to understand and awkward to
explain.

This patch works around it by running the interactive rebase
helper git-rebase--interactive with GIT_EDITOR set to ':'
when the user passes "-p" but not "-i" to the rebase command.
The effect is that the interactive rebase helper is used but
the user never sees an editor.

The test-case included in this patch was originally written
by Stephen Habermann <stephen@exigencecorp.com>, but has
been extensively modified since its creation.

72c69ebc03 git commit: Reformat output somewhat
Previously, we used to print something along the lines of

	Created commit abc9056 on master: Snib the sprock

but that output was sometimes confusing, as many projects use
the "subsystem: message" style of commit subjects (just like
this commit message does). When such improvements are done on
topic-branches, it's not uncommon to name the topic-branch the
same as the subsystem, leading to output like this:

	Created commit abc9056 on i386: i386: Snib the sprock

which doesn't look very nice and can be highly confusing.
This patch alters the format so that the noise-word "commit"
is dropped except when it makes the output read better and
the commit subject is put inside parentheses. We also
emphasize the detached case so that users do not overlook it
in case the commit subject is long enough to extend to the
next line. The end result looks thusly:

	normal case
	Created abc9056 (i386: Snib the sprock) on i386

	detached head
	Created DETACHED commit abc9056 (i386: Snib the sprock)

While we're at it, we rename "initial commit" to "root-commit"
to align it with the argument to 'git log', producing this:

	initial commit
	Created root-commit abc9056 (i386: Snib the sprock) on i386

Documentation/gittutorial-2.txt is updated accordingly so that
new users recognize what they're looking at.

adbc0b6b6e cygwin: Use native Win32 API for stat
lstat/stat functions in Cygwin are very slow, because they try to emulate
some *nix things that Git does not actually need. This patch adds Win32
specific implementation of these functions for Cygwin.

This implementation handles most situation directly but in some rare cases
it falls back on the implementation provided for Cygwin. This is necessary
for two reasons:

- Cygwin has its own file hierarchy, so absolute paths used in Cygwin is
  not suitable to be used Win32 API. cygwin_conv_to_win32_path can not be
  used because it automatically dereference Cygwin symbol links, also it
  causes extra syscall. Fortunately Git rarely use absolute paths, so we
  always use Cygwin implementation for absolute paths.

- Support of symbol links. Cygwin stores symbol links as ordinary using
  one of two possible formats. Therefore, the fast implementation falls
  back to Cygwin functions if it detects potential use of symbol links.

The speed of this implementation should be the same as mingw_lstat for
common cases, but it is considerable slower when the specified file name
does not exist.

Despite all efforts to make the fast implementation as robust as possible,
it may not work well for some very rare situations. I am aware only one
situation: use Cygwin mount to bind unrelated paths inside repository
together.  Therefore, the core.ignoreCygwinFSTricks configuration option is
provided, which controls whether native or Cygwin version of stat is used.
