GIT v1.5.3 Release Notes (draft)
========================
Updates since v1.5.2
--------------------
* An initial interation of Porcelain level superproject support
started to take shape.
* Thee are a handful pack-objects changes to help you cope better with
repositories with pathologically large blobs in them.
* New commands and options.
- "git-submodule" command helps you manage the projects from
the superproject that contain them.
- In addition to core.compression configuration option,
core.loosecompression and pack.compression options can
independently tweak zlib compression levels used for loose
and packed objects.
- "git-ls-tree -l" shows size of blobs pointed at by the
tree entries, similar to "/bin/ls -l".
- "git-rev-list" learned --regexp-ignore-case and
--extended-regexp options to tweak its matching logic used
for --grep fitering.
- "git-describe --contains" is a handier way to call more
obscure command "git-name-rev --tags".
- "git gc --aggressive" tells the command to spend more cycles
to optimize the repository harder.
- "git repack" can be told to split resulting packs to avoid
exceeding limit specified with "--max-pack-size".
* Updated behavior of existing commands.
- "git push" pretends that you immediately fetched back from
the remote by updating corresponding remote tracking
branches if you have any.
- The diffstat given after a merge (or a pull) honors the
color.diff configuration.
- "git-apply --whitespace=strip" removes blank lines added at
the end of the file.
- fetch over git native protocols with -v shows connection
status, and the IP address of the other end, to help
diagnosing problems.
- core.legacyheaders is no more, although we still can read
objects created in a new loose object format.
- "git-mailsplit" (hence "git-am") can read from Maildir
formatted mailboxes.
- "git cvsserver" does not barf upon seeing "cvs login"
request.
- "pack-objects" honors "delta" attribute set in
.gitattributes. It does not attempt to deltify blobs that
come from paths with delta attribute set to false.
- new-workdir script (in contrib) can now be used with a bare
repository.
* Builds
-
* Performance Tweaks
- git-pack-objects avoids re-deltification cost by caching
small enough delta results it creates while looking for the
best delta candidates.
- diff-delta code that is used for packing has been improved
to work better on big files.
- when there are more than one pack files in the repository,
the runtime used to try finding an object always from the
newest packfile; it now tries the same packfile as we found
the object requested the last time, which exploits the
locality of references.
Fixes since v1.5.2
------------------
All of the fixes in v1.5.2 maintenance series are included in
this release, unless otherwise noted.
* Bugfixes
- .... This has not
been backported to 1.5.2.x series, as it is rather an
intrusive change.

git-applymbox(1)
================
NAME
----
git-applymbox - Apply a series of patches in a mailbox
SYNOPSIS
--------
'git-applymbox' [-u] [-k] [-q] [-m] ( -c .dotest/<num> | <mbox> ) [ <signoff> ]
DESCRIPTION
-----------
Splits mail messages in a mailbox into commit log message,
authorship information and patches, and applies them to the
current branch.
OPTIONS
-------
-q::
Apply patches interactively. The user will be given
opportunity to edit the log message and the patch before
attempting to apply it.
-k::
Usually the program 'cleans up' the Subject: header line
to extract the title line for the commit log message,
among which (1) remove 'Re:' or 're:', (2) leading
whitespaces, (3) '[' up to ']', typically '[PATCH]', and
then prepends "[PATCH] ". This flag forbids this
munging, and is most useful when used to read back 'git
format-patch -k' output.
-m::
Patches are applied with `git-apply` command, and unless
it cleanly applies without fuzz, the processing fails.
With this flag, if a tree that the patch applies cleanly
is found in a repository, the patch is applied to the
tree and then a 3-way merge between the resulting tree
and the current tree.
-u::
Pass `-u` flag to `git-mailinfo` (see gitlink:git-mailinfo[1]).
The proposed commit log message taken from the e-mail
are re-coded into UTF-8 encoding (configuration variable
`i18n.commitencoding` can be used to specify project's
preferred encoding if it is not UTF-8). This used to be
optional but now it is the default.
+
Note that the patch is always used as-is without charset
conversion, even with this flag.
-n::
Pass `-n` flag to `git-mailinfo` (see
gitlink:git-mailinfo[1]).
-c .dotest/<num>::
When the patch contained in an e-mail does not cleanly
apply, the command exits with an error message. The
patch and extracted message are found in .dotest/, and
you could re-run 'git applymbox' with '-c .dotest/<num>'
flag to restart the process after inspecting and fixing
them.
<mbox>::
The name of the file that contains the e-mail messages
with patches. This file should be in the UNIX mailbox
format. See 'SubmittingPatches' document to learn about
the formatting convention for e-mail submission.
<signoff>::
The name of the file that contains your "Signed-off-by"
line. See 'SubmittingPatches' document to learn what
"Signed-off-by" line means. You can also just say
'yes', 'true', 'me', or 'please' to use an automatically
generated "Signed-off-by" line based on your committer
identity.

NAME
----
git-applypatch - Apply one patch extracted from an e-mail
SYNOPSIS
--------
'git-applypatch' <msg> <patch> <info> [<signoff>]
DESCRIPTION
-----------
This is usually not what an end user wants to run directly. See
gitlink:git-am[1] instead.
Takes three files <msg>, <patch>, and <info> prepared from an
e-mail message by 'git-mailinfo', and creates a commit. It is
usually not necessary to use this command directly.
This command can run `applypatch-msg`, `pre-applypatch`, and
`post-applypatch` hooks. See link:hooks.html[hooks] for more
information.
OPTIONS
-------
<msg>::
Commit log message (sans the first line, which comes
from e-mail Subject stored in <info>).
<patch>::
The patch to apply.
<info>::
Author and subject information extracted from e-mail,
used on "author" line and as the first line of the
commit log message.

git-submodule(1)
================
NAME
----
git-submodule - Initialize, update or inspect submodules
SYNOPSIS
--------
'git-submodule' [--quiet] [--cached] [status|init|update] [--] [<path>...]
COMMANDS
--------
status::
Show the status of the submodules. This will print the SHA-1 of the
currently checked out commit for each submodule, along with the
submodule path and the output of gitlink:git-describe[1] for the
SHA-1. Each SHA-1 will be prefixed with `-` if the submodule is not
initialized and `+` if the currently checked out submodule commit
does not match the SHA-1 found in the index of the containing
repository. This command is the default command for git-submodule.
init::
Initialize the submodules, i.e. clone the git repositories specified
in the .gitmodules file and checkout the submodule commits specified
in the index of the containing repository. This will make the
submodules HEAD be detached.
update::
Update the initialized submodules, i.e. checkout the submodule commits
specified in the index of the containing repository. This will make
the submodules HEAD be detached.
OPTIONS
-------
-q, --quiet::
Only print error messages.
--cached::
Display the SHA-1 stored in the index, not the SHA-1 of the currently
checked out submodule commit. This option is only valid for the
status command.
<path>::
Path to submodule(s). When specified this will restrict the command
to only operate on the submodules found at the specified paths.
FILES
-----
When cloning submodules, a .gitmodules file in the top-level directory
of the containing repository is used to find the url of each submodule.
This file should be formatted in the same way as $GIR_DIR/config. The key
to each submodule url is "module.$path.url".

## "dotest" is my stupid name for my patch-application script, which
## I never got around to renaming after I tested it. We're now on the
## second generation of scripts, still called "dotest".
##
## Update: Ryan Anderson finally shamed me into naming this "applymbox".
##
## You give it a mbox-format collection of emails, and it will try to
## apply them to the kernel using "applypatch"
##
## The patch application may fail in the middle. In which case:
## (1) look at .dotest/patch and fix it up to apply
## (2) re-run applymbox with -c .dotest/msg-number for the current one.
## Pay a special attention to the commit log message if you do this and
## use a Signoff_file, because applypatch wants to append the sign-off
## message to msg-clean every time it is run.
##
## git-am is supposed to be the newer and better tool for this job.
