Set up remotes/origin to track all remote branches.
This implements the idea Daniel Barkalow came up with, to match
the remotes/origin created by clone by default to the workflow I
use myself in my guinea pig repository, to have me eat my own
dog food.
We probably would want to use either .git/refs/local/heads/*
(idea by Linus) or .git/refs/heads/origin/* instead to reduce
the local ref namespace pollution.
git-status: do not mark unmerged paths as committable.
An unmerged path appears as both "Updated but not checked in" list,
and "Changed but not updated" list. We are not going to commit that
path until it is resolved, so remove it from the former list.
ls-files: --others should not say unmerged paths are unknown.
Jon Loeliger noticed that an unmerged path appears as
"Untracked" in git-status output, even though we show the same
path as updated/changed. Since --others means "we have not told
git about that path", we should not show unmerged paths --
obviously, git knows about them; it just does not know what we
want to do about them yet.
There's no standard libexpat for OSX, so if you install it
after-market, it can end up in various directories. Give
paths used by fink and darwinports by default to CFLAGS.
The doc installation was flattened, breaking links to howto/.
Silly cut&paste error made git-doc depend on tk8.4. Doh.
Move most of the documentation (except manuals) to git-doc.
I think the original intention was to make CFLAGS overridable
from the make command line, but somehow we ended up accumulating
conditional makefile sections that wrongly appends values to
CFLAGs. These assignments do not work when the user actually
override them from the make command line!
DEFINES are handled the same way; it was seemingly overridable,
but the makefile sections had assignments, which meant
overriding it from the command line broke things.
This simplifies things by limiting the internal futzing to
ALL_CFLAGS, and by removing DEFINES altogether. Overriding
CFLAGS from the command line should start working with this
change.
git-fetch: fail if specified refspec does not match remote.
'git-fetch remote no-such-ref' succeeded without fetching any
ref from the remote. Detect such case and report an error.
Note that this makes 'git-fetch remote master master' to fail,
because the remote branch 'master' matches the first refspec,
and the second refspec is left unmatched, which is detected by
the error checking logic. This is somewhat unintuitive, but
giving the same refspec more than once to git-fetch is useless
in any case so it should not be much of a problem. I'd accept a
patch to change this if somebody cares enough, though.
Josef Weidendorfer points out that git-clone documentation does not
mention the initial copying of remote branch heads into corresponding
local branches. Also clarify the purpose of the ref mappings description
in the "remotes" file and recommended workflow.
We checked the result of patch application for full permission bits,
when the only thing we cared about was to make sure the executable
bit was correctly set.
If we let cpio to create the leading directories implicitly,
it ends up having funny perm bits (GNU cpio 2.5 and 2.6, at least).
This leaves .git/object/?? directories readable only by the owner.
We do not accept multiple <refspecs> on one Pull:/Push: line
right now (we could lift this tentative workaround for the
broken refnames), but we have always accepted multiple such
lines, so use that form in the examples and discussion.
Also explicitly mention that Octopus is made only with an
explicit command line request and never from Pull: lines.
Clarified and added notes for pull/push refspecs.
Converted to back-ticks for literal text examples.
[jc: Also fixed git-pull description that still talked about its
calling git-resolve or git-octopus (we do not anymore; instead
we just call git-merge). BTW, I am reasonably impressed by how
well "git-am -3" applied this patch, which had some conflicts
because I've updated the documentation somewhat.]

Having the temporary files in the working tree root when making
tags is not as bad because it does not involve 'git status' as
the git-commit case, but this makes things more consistent.
Remove the temp file if it is empty after the request has failed
After using cg-update to pull, empty files named *.temp are left in
the various subdirectories of .git/objects/. These are created by
git-http-fetch to hold data as it's being fetched from the remote
repository. They are left behind after a transfer error so that the
next time git-http-fetch runs it can pick up where it left off. If
they're empty though, it would make more sense to delete them rather
than leaving them behind for the next attempt.

git-merge expects this check to be done appropriately by the
merge strategy backends. In the case of merge-ours strategy,
the resulting tree comes what we have in the index file, so it
must match the current HEAD; otherwise it would not be "ours"
merge.
This adds the coolest merge strategy ever, "ours". It can take
arbitrary number of foreign heads and merge them into the
current branch, with the resulting tree always taken from our
branch head, hence its name.
What this means is that you can declare that the current branch
supersedes the development histories of other branches using
this merge strategy.
With --no-commit flag, git-pull will perform the merge but pretends as
if the merge needed a hand resolve even if automerge cleanly resolves,
to give the user a chance to add further changes and edit the commit
message.
One caller of deref_tag() was not careful enough to make sure
what deref_tag() returned was not NULL (i.e. we found a tag
object that points at an object we do not have). Fix it, and
warn about refs that point at such an incomplete tag where
needed.
For everyone cursed by dos/windows line endings (aka CRLF):
The code reading the .gitignore files (excludes and excludes per
directory) leaves \r in the patterns, which causes fnmatch to fail for
no obvious reason. Just remove a "\r" preceding a "\n"
unconditionally.
"git-checkout -b frotz/nitfol master" failed to create
$GIT_DIR/refs/heads/frotz/nitfol but went ahead and updated
$GIT_DIR/HEAD to point at it, resulting in a corrupt repository.
Exit when we cannot create the new branch with an error status.
While we are at it, there is no reason to forbid subdirectories
in refs/heads, so make sure we handle that correctly.
The newly cloned repository by default had .git/remotes/origin
set up to track the remote master to origin, but forgot to
create the origin branch ourselves. Also it hardcoded the
assumption that the remote HEAD points at "master", which may
not always be true.

Do not install backward compatibility links anymore.
This is a companion patch to 4f9dcf7e5cf6c82455925102d315daf3b833e6d6
which stops mentioning the old command names. As promised, we do not
install symlinks to let people use backward compatibility names anymore.
cmd-rename.sh script is still shipped to help people who installed
previous git by hand to clean up the leftover symlinks.
Needed because generating a target paths will add another slash.
This fixes e.g. "git-mv file dir/", which removed "file" from

Document the use of "current directory" as pull source.

special case the current directory can be specified to perform

Add examples for git-log documentation and others.
I don't think people really follow the links or think very abstractly at

So I was thinking more of some explicit examples. I actually think every

Of course, I'm not exactly "Mr Documentation", and I don't know that this

The require statement at the top of git-svnimport seems to confuse
rpmbuild dependency generation. It uses the newer notation "v5.8.0",
and rpm ends up requiring "perl(v5.8.0)", while we would want it to
say something like "perl >= 0:5.008".
Ryan suggests old-style "require 5.008" might fix this problem, so
here it is.
* 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].
The latest init-db does not create .git/objects/??/ directories
anymore and expects the users of the repository to create them
as they are needed. local-fetch was not taught about it, which
broke local cloning with Cogito.

This implements three things (trying very hard to be backwards
compatible):
It sends the "multi_ack" capability via the mechanism proposed by
Sergey Vlasov.
When the client sends "multi_ack" with at least one "want", multi_ack
is enabled.
When multi_ack is enabled, "continue" is appended to each "ACK" until
either the server can not store more refs, or "done" is received.
In contrast to the original protocol, as long as "continue" is sent,
flushes are answered by a "NAK" (not just until an "ACK" was sent),
and if "continue" was sent at least once, the last message is an
"ACK" without "continue".

Subject: [PATCH] git-fetch-pack: Do not use git-rev-list
The code used to call git-rev-list to enumerate the local revisions.
A disadvantage of that method was that git-rev-list, lacking a
control apart from the command line, would happily enumerate
ancestors of acknowledged common commits, which was just taking
unnecessary bandwidth.
Therefore, do not use git-rev-list on the fetching side, but rather
construct the list on the go. Send the revisions starting from the
local heads, ignoring the revisions known to be common.

The new option, --numstat, shows number of inserted and deleted
lines for each path. It is similar to --stat output but is
meant to be more machine friendly by giving number of added and
deleted lines and unabbreviated paths.
- we don't allow "." and ".." as components of a refname. Thus get_sha1()
will not accept "./refname" as being the same as "refname" any more.
- git-rev-parse stops doing revision translation after seeing a pathname,
to match the brhaviour of all the tools (once we see a pathname,
everything else will also be parsed as a pathname).
Basically, if you did
git log *
and "gitk" was somewhere in the "*", we don't want to replace the filename
"gitk" with the SHA1 of the branch with the same name.
Of course, if there is any change of ambiguity, you should always use "--"
to make it explicit what are filenames and what are revisions, but this
makes the normal cases sane. The refname rule also means that instead of
the "--", you can do the same thing we're used to doing with filenames
that start with a slash: use "./filename" instead, and now it's a
filename, not an option (and not a revision).
So "git log ./*.c" is now actually a perfectly valid thing to do, even if
the first C-file might have the same name as a branch.
where the "./gitk" isn't seen as a revision, and the second "gitk" is a
filename simply because we've seen filenames already, and thus stopped
doing revision parsing.

The git philosophy when it comes to disk accesses is "Laugh in the face of
danger".
Notably, since we never modify an existing object, we don't really care
that deeply about flushing things to disk, since even if the machine
crashes in the middle of a git operation, you can never really have lost
any old work. At most, you'd need to figure out the proper heads (which
git-fsck-objects can do for you) and re-do the operation.
However, there's two exceptions to this: pruning and repacking. Those
operations will actually _delete_ old objects that they know about in
other ways (ie that they just repacked, or that they have found in other
places).
However, since they actually modify old state, we should thus be a bit
more careful about them. If the machine crashes and the duplicate new
objects haven't been flushed to disk, you can actually be in trouble.
This is trivially stupid about it by calling "sync" before removing the
objects. Not very smart, but we're talking about special operations than
are usually done once a week if that.
