+GIT v1.5.6.4 Release Notes
+==========================
+
+Fixes since v1.5.6.3
+--------------------
+
+* Various commands could overflow its internal buffer on a platform
+ with small PATH_MAX value in a repository that has contents with
+ long pathnames.
+
+* There wasn't a way to make --pretty=format:%<> specifiers to honor
+ .mailmap name rewriting for authors and committers. Now you can with
+ %aN and %cN.
+
+* Bash completion wasted too many cycles; this has been optimized to be
+ usable again.
+
+* Bash completion lost ref part when completing something like "git show
+ pu:Makefile".
+
+* "git-cvsserver" did not clean up its temporary working area after annotate
+ request.
+
+* "git-daemon" called syslog() from its signal handler, which was a
+ no-no.
+
+* "git-fetch" into an empty repository used to remind that the fetch will
+ be huge by saying "no common commits", but this was an unnecessary
+ noise; it is already known by the user anyway.
+
+* "git-mailinfo" (hence "git-am") did not correctly handle in-body [PATCH]
+ line to override the commit title taken from the mail Subject header.
+
+* "git-rebase -i -p" lost parents that are not involved in the history
+ being rewritten.
+
+Contains other various documentation fixes.

* "git-add -i" has a new action 'e/dit' to allow you edit the patch hunk
manually.

* git-apply can handle a patch that touches the same path more than once
much better than before.
similar to the way git-checkout reports by how many commits your branch
is ahead/behind.
+* git-branch's --contains option used to always require a commit parameter
+ to limit the branches with; it now defaults to list branches that
+ contains HEAD if this parameter is omitted.
+
+* git-branch's --merged and --no-merged option used to always limit the
+ branches relative to the HEAD, but they can now take an optional commit
+ argument that is used in place of HEAD.
+
* git-bundle can read the revision arguments from the standard input.
* git-cherry-pick can replay a root commit now.
* fast-export learned to export and import marks file; this can be used to
interface with fast-import incrementally.
+* git-rebase records the original tip of branch in ORIG_HEAD before it is
+ rewound.
+
* "git rerere" can be told to update the index with auto-reused resolution
with rerere.autoupdate configuration variable.
* git-send-mail can talk not just over SSL but over TLS now.
+* git-shortlog honors custom output format specified with "--pretty=format:".
+
* "git-stash save" learned --keep-index option. This lets you stash away the
local changes and bring the changes staged in the index to your working
tree for examination and testing.

DESCRIPTION
-----------
-With no arguments given a list of existing branches
-will be shown, the current branch will be highlighted with an asterisk.
-Option `-r` causes the remote-tracking branches to be listed,
-and option `-a` shows both.
-With `--contains <commit>`, shows only the branches that
-contains the named commit (in other words, the branches whose
-tip commits are descendant of the named commit).
-With `--merged`, only branches merged into HEAD will be listed, and
-with `--no-merged` only branches not merged into HEAD will be listed.

+be highlighted with an asterisk. Option `-r` causes the remote-tracking
+branches to be listed, and option `-a` shows both.
+
+With `--contains`, shows only the branches that contains the named commit
+(in other words, the branches whose tip commits are descendant of the
+named commit). With `--merged`, only branches merged into the named
+commit (i.e. the branches whose tip commits are reachable from the named
+commit) will be listed. With `--no-merged` only branches not merged into
+the named commit will be listed. Missing <commit> argument defaults to
+'HEAD' (i.e. the tip of the current branch).
In its second form, a new branch named <branchname> will be created.
It will start out with a head equal to the one given as <start-point>.
Usually the command automatically creates a commit with
a commit log message stating which commit was
cherry-picked. This flag applies the change necessary
- to cherry-pick the named commit to your working tree,
- but does not make the commit. In addition, when this
- option is used, your working tree does not have to match

You may have local modifications in the working tree files. In
other words, 'git-diff' is allowed to report changes.

--------
add::
Add the given repository as a submodule at the given path
- to the changeset to be committed next. If path is a valid
- repository within the project, it is added as is. Otherwise,
- repository is cloned at the specified path. path is added to the
- changeset and registered in .gitmodules. If no path is
- specified, the path is deduced from the repository specification.
- If the repository url begins with ./ or ../, it is stored as
- given but resolved as a relative path from the main project's
- url when cloning.
+ to the changeset to be committed next to the current
+ project: the current project is termed termed the "superproject".
++
+This requires two arguments: <repository> and <path>.
++
+<repository> is the URL of the new submodule's origin repository.
+This may be either an absolute URL, or (if it begins with ./
+or ../), the location relative to the superproject's origin
+repository.
++
+<path> is the relative location for the cloned submodule to
+exist in the superproject. If <path> does not exist, then the
+submodule is created by cloning from the named URL. If <path> does
+exist and is already a valid git repository, then this is added
+to the changeset without cloning. This second form is provided
+to ease creating a new submodule from scratch, and presumes
+the user will later push the submodule to the given URL.
++
+In either case, the given URL is recorded into .gitmodules for
+use by subsequent users cloning the superproject. If the URL is
+given relative to the superproject's repository, the presumption
+is the superproject and submodule repositories will be kept
+together in the same relative location, and only the
+superproject's URL need be provided: git-submodule will correctly
+locate the submodule using the relative URL in .gitmodules.
status::
Show the status of the submodules. This will print the SHA-1 of the
<path>::
Path to submodule(s). When specified this will restrict the command
to only operate on the submodules found at the specified paths.

FILES
-----
Bob begins with:
------------------------------------------------
-$ git clone /home/alice/project myrepo
+bob$ git clone /home/alice/project myrepo
------------------------------------------------
This creates a new directory "myrepo" containing a clone of Alice's
------------------------------------------------
(edit files)
-$ git commit -a
+bob$ git commit -a
(repeat as necessary)
------------------------------------------------
at /home/bob/myrepo. She does this with:
------------------------------------------------
-$ cd /home/alice/project
-$ git pull /home/bob/myrepo master
+alice$ cd /home/alice/project
+alice$ git pull /home/bob/myrepo master
------------------------------------------------
This merges the changes from Bob's "master" branch into Alice's
The "pull" command thus performs two operations: it fetches changes
from a remote branch, then merges them into the current branch.
+Note that in general, Alice would want her local changes committed before
+initiating this "pull". If Bob's work conflicts with what Alice did since
+their histories forked, Alice will use her working tree and the index to
+resolve conflicts, and existing local changes will interfere with the
+conflict resolution process (git will still perform the fetch but will
+refuse to merge --- Alice will have to get rid of her local changes in
+some way and pull again when this happens).
+
+Alice can peek at what Bob did without merging first, using the "fetch"
+command; this allows Alice to inspect what Bob did, using a special
+symbol "FETCH_HEAD", in order to determine if he has anything worth
+pulling, like this:
+
+------------------------------------------------
+alice$ git fetch /home/bob/myrepo master
+alice$ git log -p ..FETCH_HEAD
+------------------------------------------------
+
+This operation is safe even if Alice has uncommitted local changes.
+
+After inspecting what Bob did, if there is nothing urgent, Alice may
+decide to continue working without pulling from Bob. If Bob's history
+does have something Alice would immediately need, Alice may choose to
+stash her work-in-progress first, do a "pull", and then finally unstash
+her work-in-progress on top of the resulting history.
+
When you are working in a small closely knit group, it is not
unusual to interact with the same repository over and over
again. By defining 'remote' repository shorthand, you can make
it easier:
------------------------------------------------
-$ git remote add bob /home/bob/myrepo
+alice$ git remote add bob /home/bob/myrepo
------------------------------------------------
-With this, Alice can perform the first operation alone using the
+With this, Alice can perform the first part of the "pull" operation alone using the
'git-fetch' command without merging them with her own branch,
using:
-------------------------------------
-$ git fetch bob
+alice$ git fetch bob
-------------------------------------
Unlike the longhand form, when Alice fetches from Bob using a
`bob/master`. So after this:
-------------------------------------
-$ git log -p master..bob/master
+alice$ git log -p master..bob/master
-------------------------------------
shows a list of all the changes that Bob made since he branched from
could merge the changes into her master branch:
-------------------------------------
-$ git merge bob/master
+alice$ git merge bob/master
-------------------------------------
This `merge` can also be done by 'pulling from her own remote
tracking branch', like this:
-------------------------------------
-$ git pull . remotes/bob/master
+alice$ git pull . remotes/bob/master
-------------------------------------
Note that git pull always merges into the current branch,
Later, Bob can update his repo with Alice's latest changes using
-------------------------------------
-$ git pull
+bob$ git pull
-------------------------------------
Note that he doesn't need to give the path to Alice's repository;
used for pulls:
-------------------------------------
-$ git config --get remote.origin.url
+bob$ git config --get remote.origin.url
/home/alice/project
-------------------------------------
name "origin/master":
-------------------------------------
-$ git branch -r
+bob$ git branch -r
origin/master
-------------------------------------
perform clones and pulls using the ssh protocol:
-------------------------------------
-$ git clone alice.org:/home/alice/project myrepo
+bob$ git clone alice.org:/home/alice/project myrepo
-------------------------------------
Alternatively, git has a native protocol, or can use rsync or http;
