Subject: On Cygwin, use symbolic ref, not a symbolic link, to express
 .git/HEAD

H. Peter Anvin says that Samba "promotes" symlinks to hardlinks while
Cygwin itself uses .lnk files to emulate symlinks.  Avoid using symbolic
link for .git/HEAD on Cygwin.

This does not help the symlinks recorded in trees as user data, but
at least we do not use them for our own bookkeeping.

It reorganizes the code and also has saner command line options
syntax.  Unlike git-applymbox, it can take more than one mailbox
file from the command line, as well as reading from the standard
input when '-' is specified.

Subject: [PATCH] If NO_MMAP is defined, fake mmap() and munmap()

Since some platforms do not support mmap() at all, and others do only just
so, this patch introduces the option to fake mmap() and munmap() by
malloc()ing and read()ing explicitely.

Subject: Makefile: avoid error message from 'uname -o'

The platform specific tweaking part was using 'uname -o' which
is not always available.  Squelch error message from it.

It was suggested to chain the if..else, but I chose not to, because
maintaining the nested if..else if..else..endif endif to match is a
pain.  If we had "elif", things would have been different, though.
While we are at it, try not to invoke 'uname -s' for each platform
candidate.

Subject: New: git-svnimport.

As the name suggests, this script imports from SVN.

Only "normal" SVN repositories (with single trunk/, branches/, and tags/
subdrectories) are supported. Incremental imports require preserving
the file .git/svn2git.

+NAME
+----
+git-svnimport - Import a SVN repository into git
+
+
+SYNOPSIS
+--------
+'git-svnimport' [ -o <branch-for-HEAD> ] [ -h ] [ -v ]
+			[ -C <GIT_repository> ] [ -i ] [ -u ]
+			[ -b branch_subdir ] [ -t trunk_subdir ] [ -T tag_subdir ]
+			[ -m ] [ -M regex ] [ <SVN_repository_URL> ]
+
+
+DESCRIPTION
+-----------
+Imports a SVN repository into git. It will either create a new
+repository, or incrementally import into an existing one.
+
+SVN access is done by the SVN:: Perl module.
+
+git-svnimport assumes that SVN repositories are organized into one
+"trunk" directory where the main development happens, "branch/FOO"
+directories for branches, and "/tags/FOO" directories for tags.
+Other subdirectories are ignored.
+
+git-svnimport creates a file ".git/svn2git", which is required for
+incremental SVN imports. 
+
+OPTIONS
+-------
+-C <target-dir>::
+        The GIT repository to import to.  If the directory doesn't
+        exist, it will be created.  Default is the current directory.
+
+-i::
+	Import-only: don't perform a checkout after importing.  This option
+	ensures the working directory and cache remain untouched and will
+	not create them if they do not exist.
+
+-t <trunk_subdir>::
+	Name the SVN trunk. Default "trunk".
+	
+-T <tag_subdir>::
+	Name the SVN subdirectory for tags. Default "tags".
+	
+-b <branch_subdir>::
+	Name the SVN subdirectory for branches. Default "branches".
+	
+-o <branch-for-HEAD>::
+	The 'trunk' branch from SVN is imported to the 'origin' branch within
+	the git repository. Use this option if you want to import into a
+	different branch.
+
+-m::    
+	Attempt to detect merges based on the commit message. This option
+	will enable default regexes that try to capture the name source 
+	branch name from the commit message. 
+
+-M <regex>::
+	Attempt to detect merges based on the commit message with a custom
+	regex. It can be used with -m to also see the default regexes. 
+	You must escape forward slashes. 
+
+-v::
+	Verbosity: let 'svnimport' report what it is doing.
+
+<SVN_repository_URL>::
+	The URL of the SVN module you want to import. For local
+	repositories, use "file:///absolute/path".
+
+-h::
+	Print a short usage message and exit.
+
+OUTPUT
+------
+If '-v' is specified, the script reports what it is doing.
+
+Otherwise, success is indicated the Unix way, i.e. by simply exiting with
+a zero exit status.
+
+Author
+------
+Written by Matthias Urlichs <smurf@smurf.noris.de>, with help from
+various participants of the git-list <git@vger.kernel.org>.
+
+Based on a cvs2git script by the same author.

From 17712991a59824a8d22d5115c0c154d3122fc17b Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@osdl.org>

Subject: Add ".git/config" file parser

This is a first cut at a very simple parser for a git config file.

The format of the file is a simple ini-file like thing, with simple
variable/value pairs. You can (and should) make the variables have a
simple single-level scope, ie a valid file looks something like this:

	#
	# This is the config file, and
	# a '#' or ';' character indicates
	# a comment
	#

	; core variables
	[core]
		; Don't trust file modes
		filemode = false

	; Our diff algorithm
	[diff]
		external = "/usr/local/bin/gnu-diff -u"
		renames = true

which parses into three variables: "core.filemode" is associated with the
string "false", and "diff.external" gets the appropriate quoted value.

Right now we only react to one variable: "core.filemode" is a boolean that
decides if we should care about the 0100 (user-execute) bit of the stat
information. Even that is just a parsing demonstration - this doesn't
actually implement that st_mode compare logic itself.

Different programs can react to different config options, although they
should always fall back to calling "git_default_config()" on any config
option name that they don't recognize.

Date: Tue, 11 Oct 2005 18:47:34 -0700
Subject: Use git config file for committer name and email info

This starts using the "user.name" and "user.email" config variables if
they exist as the default name and email when committing.  This means
that you don't have to use the GIT_COMMITTER_EMAIL environment variable
to override your email - you can just edit the config file instead.

The patch looks bigger than it is because it makes the default name and
email information non-static and renames it appropriately.  And it moves
the common git environment variables into a new library file, so that
you can link against libgit.a and get the git environment without having
to link in zlib and libcrypt.

In short, most of it is renaming and moving, the real change core is
just a few new lines in "git_default_config()" that copies the user
config values to the new base.

It also changes "git-var -l" to list the config variables.

From 9cf6d3357aaaaa89dd86cc156221b7b604e9358c Mon Sep 17 00:00:00 2001
From: Sergey Vlasov <vsu@altlinux.ru>
Date: Wed, 12 Oct 2005 12:01:31 -0700
Subject: Add git-index-pack utility

git-index-pack builds a pack index file for an existing packed
archive.  With this utility a packed archive which was transferred
without the corresponding pack index can be added to objects/pack/
without repacking.

+=================
+
+NAME
+----
+git-index-pack - Build pack index file for an existing packed archive
+
+
+SYNOPSIS
+--------
+'git-index-pack' [-o <index-file>] <pack-file>
+
+
+DESCRIPTION
+-----------
+Reads a packed archive (.pack) from the specified file, and
+builds a pack index file (.idx) for it.  The packed archive
+together with the pack index can then be placed in the
+objects/pack/ directory of a git repository.
+
+
+OPTIONS
+-------
+-o <index-file>::
+	Write the generated pack index into the specified
+	file.  Without this option the name of pack index
+	file is constructed from the name of packed archive
+	file by replacing .pack with .idx (and the program
+	fails if the name of packed archive does not end
+	with .pack).

Subject: Add findtags - reworked

A short perl script that will walk the tag refs, tag objects, and even commit
objects in its quest to figure out whether the given SHA1 (for a commit or
tree) was ever tagged.

This version is reworked incorporating sanity, feature and style fixes from
Junio.

Usage: git-findtags.perl [ -t ] <commit-or-tree-sha1>

Subject: Unlocalized isspace and friends

Do our own ctype.h, just to get the sane semantics: we want
locale-independence, _and_ we want the right signed behaviour. Plus we
only use a very small subset of ctype.h anyway (isspace, isalpha,
isdigit and isalnum).

Subject: git-check-ref-format: reject funny ref names.

Update check_ref_format() function to reject ref names that:

 * has a path component that begins with a ".", or
 * has a double dots "..", or
 * has ASCII control character, "~", "^", ":" or SP, anywhere, or
 * ends with a "/".

Use it in 'git-checkout -b', 'git-branch', and 'git-tag' to make sure
that newly created refs are well-formed.

Date: Thu, 20 Oct 2005 21:05:05 -0700
Subject: Split up tree diff functions into tree-diff.c library

This makes the tree diff functionality independent of the "git-diff-tree"
program, by splitting the core functionality up into a library file.

This will be needed for when we teach git-rev-list to only follow a
specified set of pathnames, rather than the global revision history.

Most of it is a fairly straightforward code move, but it also involves
some calling convention cleanup, and moving some of the static variables
from diff-tree.c into the options structure.

The actual tree change callback routines also become paramterized by the
diff_options structure, allowing the library functionality to do something
else than just show the diff on stdout.

Right now the only user of this functionality remains git-diff-tree
itself.

From 1114b26e8f2d06912d855c631e51a4ee8a06c4e2 Mon Sep 17 00:00:00 2001
From: Josef Weidendorfer <Josef.Weidendorfer@gmx.de>
Date: Sun, 23 Oct 2005 18:15:34 +0200
Subject: Add git-mv

It supersedes git-rename by adding functionality to move multiple
files, directories or symlinks into another directory.  It also
provides according documentation.

The implementation renames multiple files, using the arguments from
the command line to produce an array of sources and destinations.  In
a first pass, all requested renames are checked for errors, and
overwriting of existing files is only allowed with '-f'.  The actual
renaming is done in a second pass.  This ensures that any error
condition is checked before anything is changed.

+git-mv(1)
+=========
+
+NAME
+----
+git-mv - Script used to move or rename a file, directory or symlink.
+
+
+SYNOPSIS
+--------
+'git-mv' [-f] [-n] <source> <destination>
+'git-mv' [-f] [-k] [-n] <source> ... <destination directory>
+
+DESCRIPTION
+-----------
+This script is used to move or rename a file, directory or symlink.
+In the first form, it renames <source>, which must exist and be either
+a file, symlink or directory, to <destination>, which must not exist.
+In the second form, the last argument has to be an existing
+directory; the given sources will be moved into this directory.
+
+The index is updated after successful completion, but the change must still be
+committed.
+
+OPTIONS
+-------
+-f::
+	Force renaming or moving even targets exist
+-k::
+        Skip move or rename actions which would lead to an error
+	condition. An error happens when a source is neither existing nor
+        controlled by GIT, or when it would overwrite an existing
+        file unless '-f' is given.
+-n::
+	Do nothing; only show what would happen
+
+
+Author
+------
+Written by Linus Torvalds <torvalds@osdl.org>
+Rewritten by Ryan Anderson <ryan@michonline.com>
+Move functionality added by Josef Weidendorfer <Josef.Weidendorfer@gmx.de>

From 35eb2d36418a25f9e956b116a622d8d99f4abad9 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@osdl.org>
Date: Sun, 23 Oct 2005 14:30:45 -0700
Subject: Add git-shell.

This adds a very git specific restricted shell, that can be
added to /etc/shells and set to the pw_shell in the /etc/passwd
file, to give users ability to push into repositories over ssh
without giving them full interactive shell acount.

[jc: I updated Linus' patch to match what the current sq_quote()
 does.]

Subject: pack-objects: Allow use of pre-generated pack.

git-pack-objects can reuse pack files stored in $GIT_DIR/pack-cache
directory, when a necessary pack is found.  This is hopefully useful
when upload-pack (called from git-daemon) is expected to receive
requests for the same set of objects many times (e.g full cloning
request of any project, or updates from the set of heads previous day
to the latest for a slow moving project).

Currently git-pack-objects does *not* keep pack files it creates for
reusing.  It might be useful to add --update-cache option to it,
which would allow it store pack files it created in the pack-cache
directory, and prune rarely used ones from it.

Subject: Add git-name-rev

git-name-rev tries to find nice symbolic names for commits. It does so by
walking the commits from the refs. When the symbolic name is ambiguous, the
following heuristic is applied: Try to avoid too many ~'s, and if two ambiguous
names have the same count of ~'s, take the one whose last number is smaller.

With "--tags", the names are derived only from tags.

With "--stdin", the stdin is parsed, and after every sha1 for which a name
could be found, the name is appended. (Try "git log | git name-rev --stdin".)

+NAME
+----
+git-name-rev - Find symbolic names for given revs.
+
+
+SYNOPSIS
+--------
+'git-name-rev' [--tags] ( --all | --stdin | <commitish>... )
+
+DESCRIPTION
+-----------
+Finds symbolic names suitable for human digestion for revisions given in any
+format parsable by git-rev-parse.
+
+
+OPTIONS
+-------
+
+--tags::
+	Do not use branch names, but only tags to name the commits
+
+--all::
+	List all commits reachable from all refs
+
+--stdin::
+	Read from stdin, append "(<rev_name>)" to all sha1's of name'able
+	commits, and pass to stdout
+
+EXAMPLE
+-------
+
+Given a commit, find out where it is relative to the local refs. Say somebody
+wrote you about that phantastic commit 33db5f4d9027a10e477ccf054b2c1ab94f74c85a.
+Of course, you look into the commit, but that only tells you what happened, but
+not the context.
+
+Enter git-name-rev:
+
+------------
+% git name-rev 33db5f4d9027a10e477ccf054b2c1ab94f74c85a
+------------
+
+Now you are wiser, because you know that it happened 940 revisions before v0.99.
+
+Another nice thing you can do is:
+
+------------
+% git log | git name-rev --stdin

From: Junio C Hamano <junkio@cox.net>
Date: Sat, 29 Oct 2005 14:35:11 -0700
Subject: GIT 0.99.9

Done in 0.99.9
==============

Ports
~~~~~

* Cygwin port [HPA].

* OpenBSD build [Merlyn and others].

Fixes
~~~~~

* clone request over git native protocol from a repository with
  too many refs did not work; this has been fixed.

* git-daemon got safer for kernel.org use [HPA].

* Extended SHA1 parser was not enforcing uniqueness for
  abbreviated SHA1; this has been fixed.

* http transport does not barf on funny characters in URL.

* The ref naming restrictions have been formalized and the
  coreish refuses to create funny refs; we still need to audit
  importers.  See git-check-ref-format(1).

New Features and Commands
~~~~~~~~~~~~~~~~~~~~~~~~~

* .git/config file as a per-repository configuration mechanism,
  and some commands understand it [Linus].  See
  git(7).

* The core.filemode configuration item can be used to make us a
  bit more FAT friendly.  See git(7).

* The extended SHA1 notation acquired Peel-the-onion operator
  ^{type} and ^{}.  See git-rev-parse(1).

* SVN importer [Matthias].  See git-svnimport(1).

* .git/objects/[0-9a-f]{2} directories are created on demand,
  and removed when becomes empty after prune-packed [Linus].

* Filenames output from various commands without -z option are
  quoted when they embed funny characters (TAB and LF) using
  C-style quoting within double-quotes, to match the proposed
  GNU diff/patch notation [me, but many people contributed in
  the discussion].

* git-mv is expected to be a better replacement for git-rename.
  While the latter has two parameter restriction, it acts more
  like the regular 'mv' that can move multiple things to one
  destinatino directory [Josef Weidendorfer].

* git-checkout can take filenames to revert the changes to
  them.  See git-checkout(1)

* The new program git-am is a replacement for git-applymbox that
  has saner command line options and a bit easier to use when a
  patch does not apply cleanly.

* git-ls-remote can show unwrapped onions using ^{} notation, to
  help Cogito to track tags.

* git-merge-recursive backend can merge unrelated projects.

* git-clone over native transport leaves the result packed.

* git-http-fetch issues multiple requests in parallel when
  underlying cURL library supports it [Nick and Daniel].

* git-fetch-pack and git-upload-pack try harder to figure out
  better common commits [Johannes].

* git-read-tree -u removes a directory when it makes it empty.

* git-diff-* records abbreviated SHA1 names of original and
  resulting blob; this sometimes helps to apply otherwise an
  unapplicable patch by falling back to 3-way merge.

* git-format-patch now takes series of from..to rev ranges and
  with '-m --stdout', writes them out to the standard output.
  This can be piped to 'git-am' to implement cheaper
  cherry-picking.

* git-tag takes '-u' to specify the tag signer identity [Linus].

* git-rev-list can take optional pathspecs to skip commits that
  do not touch them (--dense) [Linus].

* Comes with new and improved gitk [Paulus and Linus].
