GIT v1.5.0.3 Release Notes
==========================
Fixes since v1.5.0.2
--------------------
* Bugfixes
- 'git.el' honors the commit coding system from the configuration.
- 'blameview' in contrib/ correctly digs deeper when a line is
clicked.
- 'http-push' correctly makes sure the remote side has leading
path. Earlier it started in the middle of the path, and
incorrectly.
- 'git-merge' did not exit with non-zero status when the
working tree was dirty and cannot fast forward. It does
now.
- 'cvsexportcommit' does not lose yet-to-be-used message file.
- int-vs-size_t typefix when running combined diff on files
over 2GB long.
- 'git apply --whitespace=strip' should not touch unmodified
lines.
- 'git-mailinfo' choke when a logical header line was too long.
- 'git show A..B' did not error out. Negative ref ("not A" in
this example) does not make sense for the purpose of the
command, so now it errors out.
- 'git fmt-merge-msg --file' without file parameter did not
correctly error out.
- 'git archimport' barfed upon encountering a commit without
summary.
- 'git index-pack' did not protect itself from getting a short
read out of pread(2).
- 'git http-push' had a few buffer overruns.
- Build dependency fixes to rebuild fetch.o when other headers
change.
* Documentation updates
- user-manual updates.
- Options to 'git remote add' were described insufficiently.
- Configuration format.suffix was not documented.
- Other formatting and spelling fixes.

@@ -19,17 +19,86 @@ Updates since v1.5.0
- "git diff" learned --ignore-space-at-eol. This is a weaker
form of --ignore-space-change.
- "git diff --no-index pathA pathB" can be used as diff
replacement with git specific enhancements.
- "git diff --pretty=format:<string>" to allow more flexible
custom log output.
- "git name-rev" learned --refs=<pattern>, to limit the tags
used for naming the given revisions only to the ones
matching the given pattern.
- "git remote update" is to run "git fetch" for defined remotes
to update tracking branches.
- "git cvsimport" can now take '-d' to talk with a CVS
repository different from what are recorded in CVS/Root
(overriding it with environment CVSROOT does not work).
- "git bundle" can help sneaker-netting your changes between
repositories.
- A new configuration "core.symlinks" can be used to disable
symlinks on filesystems that do not support them; they are
checked out as regular files instead.
* Updated behaviour of existing commands.
- git-svn got almost a rewrite.
- core.autocrlf configuration, when set to 'true', makes git
to convert CRLF at the end of lines in text files to LF when
reading from the filesystem, and convert in reverse when
writing to the filesystem. The variable can be set to
'input', in which case the conversion happens only while
reading from the filesystem but files are written out with
LF at the end of lines. Currently, which paths to consider
'text' (i.e. be subjected to the autocrlf mechanism) is
decided purely based on the contents, but the plan is to
allow users to explicitly override this heuristic based on
paths.
- The behaviour of 'git-apply', when run in a subdirectory,
without --index nor --cached were inconsistent with that of
the command with these options. This was fixed to match the
behaviour with --index. A patch that is meant to be applied
with -p1 from the toplevel of the project tree can be
applied with any custom -p<n> option. A patch that is not
relative to the toplevel needs to be applied with -p<n>
option with or without --index (or --cached).
- "git diff" outputs a trailing HT when pathnames have embedded
SP on +++/--- header lines, in order to help "GNU patch" to
parse its output. "git apply" was already updated to accept
this modified output format since ce74618d (Sep 22, 2006).
- "git cvsserver" runs hooks/update and honors its exit status.
- "git cvsserver" can be told to send everything with -kb.
- "git diff --check" also honors the --color output option.
- "git name-rev" used to stress the fact that a ref is a tag too
much, by saying something like "v1.2.3^0~22". It now says
"v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
not talk about an ancestor of the commit that is tagged, which
makes sense).
- "git rev-list --boundary" now shows boundary markers for the
commits omitted by --max-age and --max-count condition.
- The configuration mechanism now reads $(prefix)/etc/gitconfig.
- "git apply --verbose" shows what preimage lines were wanted
when it couldn't find them.
- "git status" in a read-only repository got a bit saner.
- "git fetch" (hence "git clone" and "git pull") are less
noisy when the output does not go to tty.

- The sample update hook to show how to send out notification

NAME
----
git-bundle - Move objects and refs by archive
SYNOPSIS
--------
'git-bundle' create <file> [git-rev-list args]
'git-bundle' verify <file>
'git-bundle' list-heads <file> [refname...]
'git-bundle' unbundle <file> [refname...]
DESCRIPTION
-----------
Some workflows require that one or more branches of development on one
machine be replicated on another machine, but the two machines cannot
be directly connected so the interactive git protocols (git, ssh,
rsync, http) cannot be used. This command provides support for
git-fetch and git-pull to operate by packaging objects and references
in an archive at the originating machine, then importing those into
another repository using gitlink:git-fetch[1] and gitlink:git-pull[1]
after moving the archive by some means (i.e., by sneakernet). As no
direct connection between repositories exists, the user must specify a
basis for the bundle that is held by the destination repository: the
bundle assumes that all objects in the basis are already in the
destination repository.
OPTIONS
-------
create <file>::
Used to create a bundle named 'file'. This requires the
git-rev-list arguments to define the bundle contents.
verify <file>::
Used to check that a bundle file is valid and will apply
cleanly to the current repository. This includes checks on the
bundle format itself as well as checking that the prerequisite
commits exist and are fully linked in the current repository.
git-bundle prints a list of missing commits, if any, and exits
with non-zero status.
list-heads <file>::
Lists the references defined in the bundle. If followed by a
list of references, only references matching those given are
printed out.
unbundle <file>::
Passes the objects in the bundle to gitlink:git-index-pack[1]
for storage in the repository, then prints the names of all
defined references. If a reflist is given, only references
matching those in the given list are printed. This command is
really plumbing, intended to be called only by
gitlink:git-fetch[1].
[git-rev-list-args...]::
A list of arguments, acceptable to git-rev-parse and
git-rev-list, that specify the specific objects and references
to transport. For example, "master~10..master" causes the
current master reference to be packaged along with all objects
added since its 10th ancestor commit. There is no explicit
limit to the number of references and objects that may be
packaged.
[refname...]::
A list of references used to limit the references reported as
available. This is principally of use to git-fetch, which
expects to receive only those references asked for and not
necessarily everything in the pack (in this case, git-bundle is
acting like gitlink:git-fetch-pack[1]).
SPECIFYING REFERENCES
---------------------
git-bundle will only package references that are shown by
git-show-ref: this includes heads, tags, and remote heads. References
such as master~1 cannot be packaged, but are perfectly suitable for
defining the basis. More than one reference may be packaged, and more
than one basis can be specified. The objects packaged are those not
contained in the union of the given bases. Each basis can be
specified explicitly (e.g., ^master~10), or implicitly (e.g.,
master~10..master, master --since=10.days.ago).
It is very important that the basis used be held by the destination.
It is okay to err on the side of conservatism, causing the bundle file
to contain objects already in the destination as these are ignored
when unpacking at the destination.
EXAMPLE
-------
Assume two repositories exist as R1 on machine A, and R2 on machine B.
For whatever reason, direct connection between A and B is not allowed,
but we can move data from A to B via some mechanism (CD, email, etc).
We want to update R2 with developments made on branch master in R1.
We set a tag in R1 (lastR2bundle) after the previous such transport,
and move it afterwards to help build the bundle.
in R1 on A:
$ git-bundle create mybundle master ^lastR2bundle
$ git tag -f lastR2bundle master
(move mybundle from A to B by some mechanism)
in R2 on B:
$ git-bundle verify mybundle
$ git-fetch mybundle refspec
where refspec is refInBundle:localRef
Also, with something like this in your config:
[remote "bundle"]
url = /home/me/tmp/file.bdl
fetch = refs/heads/*:refs/remotes/origin/*
You can first sneakernet the bundle file to ~/tmp/file.bdl and
then these commands:
$ git ls-remote bundle
$ git fetch bundle
$ git pull bundle
would treat it as if it is talking with a remote side over the
network.

that the revision was created by SVN::Mirror (also used by SVK).

introduce a helper function that returns the original identity
URL and UUID, and use it when generating metadata in commit

If an SVN revision has a property, "svm:headrev", it is likely
that the revision was created by SVN::Mirror (also used by SVK).
The property contains a repository UUID and a revision. We want
to make it look like we are mirroring the original URL, so
introduce a helper function that returns the original identity
URL and UUID, and use it when generating metadata in commit
messages.
