879ef2485d Introduce commit notes
Commit notes are blobs which are shown together with the commit
message.  These blobs are taken from the notes ref, which you can
configure by the config variable core.notesRef, which in turn can
be overridden by the environment variable GIT_NOTES_REF.

The notes ref is a branch which contains "files" whose names are
the names of the corresponding commits (i.e. the SHA-1).

The rationale for putting this information into a ref is this: we
want to be able to fetch and possibly union-merge the notes,
maybe even look at the date when a note was introduced, and we
want to store them efficiently together with the other objects.

24b1f65fed Install git-stage in exec-path
Earlier the plan was to eventually eradicate git-foo executables from the
filesystem for all the built-in commands, but when we released 1.6.0 we
decided not to do so.  Instead, it has been promised that by prepending
the output from $(git --exec-path) to your $PATH, you can keep using the
dashed form of commands.

This also allows "git stage" to appear in the autogenerated command list,
which is used to offer man pages by "git help" command.

This introduces make variable NO_PTHREADS for platforms that lack the
support for pthreads library or people who do not want to use it for
whatever reason.  When defined, it makes the multi-threaded index
preloading into a no-op, and also disables threaded delta searching by

671c9b7e31 Add cache preload facility
This can do the lstat() storm in parallel, giving potentially much
improved performance for cold-cache cases or things like NFS that have
weak metadata caching.

Just use "read_cache_preload()" instead of "read_cache()" to force an
optimistic preload of the index stat data.  The function takes a
pathspec as its argument, allowing us to preload only the relevant
portion of the index.

310e0216c8 Stop using compat/regex.c on platforms with working regexp library
We used to have non-POSIX comformant BRE in our code, and linked with GNU
regexp library on a few platforms (Darwin, FreeBSD and AIX) to work it
around.  This was backwards.

We've fixed the broken regexps to use ERE that native regexp libraries on
these platforms can handle just fine.  There is no need to link with GNU
regexp library on these platforms anymore.

be58e70dba diff: unify external diff and funcname parsing code
Both sets of code assume that one specifies a diff profile
as a gitattribute via the "diff=foo" attribute. They then
pull information about that profile from the config as
diff.foo.*.

The code for each is currently completely separate from the
other, which has several disadvantages:

  - there is duplication as we maintain code to create and
    search the separate lists of external drivers and
    funcname patterns

  - it is difficult to add new profile options, since it is
    unclear where they should go

  - the code is difficult to follow, as we rely on the
    "check if this file is binary" code to find the funcname
    pattern as a side effect. This is the first step in
    refactoring the binary-checking code.

This patch factors out these diff profiles into "userdiff"
drivers. A file with "diff=foo" uses the "foo" driver, which
is specified by a single struct.

Note that one major difference between the two pieces of
code is that the funcname patterns are always loaded,
whereas external drivers are loaded only for the "git diff"
porcelain; the new code takes care to retain that situation.

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.

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.

414851a42e separate build targets for man and html documentation
This introduces new build targets "man" and "html" which allow building
the documentation in the respective formats separately. This helps
people with a partial documentation build chain: html pages can be built
without xmlto.

This is documented in INSTALL now, together with corrections: Before,
instructions in INSTALL would build man+html but install man only. Now
the instructions build and install both, and new and pre-existing
targets are explained.

Note that build targets "doc" and "man" correspond to install targets
"install-doc install-html" and "install-doc" respectively. This
inconsistency is not changed, in order to keep everyone's build scripts
from breaking.

The standard libc regex library on OSX does not support alternation
in POSIX Basic Regular Expression mode.  This breaks the diff.funcname
functionality on OSX.

To fix this, we use the GNU regex library which is already present in
the compat/ diretory for the MinGW port.  However, simply adding compat/
to the COMPAT_CFLAGS variable causes a conflict between the system
fnmatch.h and the one present in compat/.  To remedy this, move the
regex and fnmatch functionality to their own subdirectories in compat/
so they can be included seperately.

8af84dadb1 git wrapper: DWIM mistyped commands
This patch introduces a modified Damerau-Levenshtein algorithm into
Git's code base, and uses it with the following penalties to show some
similar commands when an unknown command was encountered:

	swap = 0, insertion = 1, substitution = 2, deletion = 4

A typical output would now look like this:

	$ git sm
	git: 'sm' is not a git-command. See 'git --help'.

	Did you mean one of these?
		am
		rm

The cut-off is at similarity rating 6, which was empirically determined
to give sensible results.

As a convenience, if there is only one candidate, Git continues under
the assumption that the user mistyped it.  Example:

	$ git reabse
	WARNING: You called a Git program named 'reabse', which does
	not exist.
	Continuing under the assumption that you meant 'rebase'

3e073dc561 Makefile: always provide a fallback when hardlinks fail
We make hardlinks from "git" to "git-<cmd>" built-ins and have been
careful to avoid cross-device links when linking "git-<cmd>" to
gitexecdir.

However, we were not prepared to deal with a build directory that is
incapable of making hard links within itself. This patch corrects it.

Instead of temporarily linking "git" to gitexecdir, directly link "git-
add", falling back to "cp". Try hardlinking that as "git-<cmd>", falling
back to symlinks or "cp" on error.

While at it, avoid 100+ error messages from hardlink failures when we are
going to fall back to symlinks or "cp" by redirecting the standard error
to /dev/null.
