153920da5b Custom low-level merge driver: change the configuration scheme.
This changes the configuration syntax for defining a low-level
merge driver to be:

	[merge "<<drivername>>"]
		driver = "<<command line>>"
		name = "<<driver description>>"

which is much nicer to read and is extensible.  Credit goes to
Martin Waitz and Linus.

In addition, when we use an external low-level merge driver, it
is reported as an extra output from merge-recursive, using the
value of merge.<<drivername>.name variable.

The demonstration in t6026 has also been updated.

f3ef6b6bbe Custom low-level merge driver support.
This allows users to specify custom low-level merge driver per
path, using the attributes mechanism.  Just like you can specify
one of built-in "text", "binary", "union" low-level merge
drivers by saying:

	*		merge=text
	.gitignore	merge=union
	*.jpg		merge=binary

pick a name of your favorite merge driver, and assign it as the
value of the 'merge' attribute.

A custom low-level merge driver is defined via the config
mechanism.  This patch introduces 'merge.driver', a multi-valued
configuration.  Its value is the name (i.e. the one you use as
the value of 'merge' attribute) followed by a command line
specification.  The command line can contain %O, %A, and %B to
be interpolated with the names of temporary files that hold the
common ancestor version, the version from your branch, and the
version from the other branch, and the resulting command is
spawned.

The low-level merge driver is expected to update the temporary
file for your branch (i.e. %A) with the result and exit with
status 0 for a clean merge, and non-zero status for a conflicted
merge.

A new test in t6026 demonstrates a sample usage.

b9849a1ab6 Make sure quickfetch is not fooled with a previous, incomplete fetch.
This updates git-rev-list --objects to be a bit more careful
when listing a blob object to make sure the blob actually
exists, and uses it to make sure the quick-fetch optimization we
introduced earlier is not fooled by a previous incomplete fetch.

The quick-fetch optimization works by running this command:

	git rev-list --objects <<commit-list>> --not --all

where <<commit-list>> is a list of commits that we are going to
fetch from the other side.  If there is any object missing to
complete the <<commit-list>>, the rev-list would fail and die
(say, the commit was in our repository, but its tree wasn't --
then it will barf while trying to list the blobs the tree
contains because it cannot read that tree).

Usually we do not have the objects (otherwise why would we
fetching?), but in one important special case we do: when the
remote repository is used as an alternate object store
(i.e. pointed by .git/objects/info/alternates).  We could check
.git/objects/info/alternates to see if the remote we are
interacting with is one of them (or is used as an alternate,
recursively, by one of them), but that check is more cumbersome
than it is worth.

The above check however did not catch missing blob, because
object listing code did not read nor check blob objects, knowing
that blobs do not contain any further references to other
objects.  This commit fixes it with practically unmeasurable
overhead.

I've benched this with

	git rev-list --objects --all >/dev/null

in the kernel repository, with three different implementations
of the "check-blob".

 - Checking with has_sha1_file() has negligible (unmeasurable)
   performance penalty.

 - Checking with sha1_object_info() makes it somewhat slower,
   perhaps by 5%.

 - Checking with read_sha1_file() to cause a fully re-validation
   is prohibitively expensive (about 4 times as much runtime).

In my original patch, I had this as a command line option, but
the overhead is small enough that it is not really worth it.

35ebfd6a0c Define 'crlf' attribute.
This defines the semantics of 'crlf' attribute as an example.
When a path has this attribute unset (i.e. '!crlf'), autocrlf
line-end conversion is not applied.

Eventually we would want to let users to build a pipeline of
processing to munge blob data to filesystem format (and in the
other direction) based on combination of attributes, and at that
point the mechanism in convert_to_{git,working_tree}() that
looks at 'crlf' attribute needs to be enhanced.  Perhaps the
existing 'crlf' would become the first step in the input chain,
and the last step in the output chain.

have you try a commit that is half-way since the beginning of

you do not care), there is no reason not to allow this.

38a47fd6e3 Bisect: teach "bisect start" to optionally use one bad and many good revs.
One bad commit is fundamentally needed for bisect to run,
and if we beforehand know more good commits, we can narrow
the bisect space down without doing the whole tree checkout
every time we give good commits.

This patch implements:

    git bisect start [<bad> [<good>...]] [--] [<pathspec>...]

as a short-hand for this command sequence:

    git bisect start
    git bisect bad $bad
    git bisect good $good1 $good2...

On the other hand, there may be some confusion between revs
(<bad> and <good>...) and <pathspec>... if -- is not used
and if an invalid rev or a pathspec that looks like a rev is
given.

8685da4256 don't ever allow SHA1 collisions to exist by fetching a pack
Waaaaaaay back Git was considered to be secure as it never overwrote
an object it already had.  This was ensured by always unpacking the
packfile received over the network (both in fetch and receive-pack)
and our already existing logic to not create a loose object for an
object we already have.

Lately however we keep "large-ish" packfiles on both fetch and push
by running them through index-pack instead of unpack-objects.  This
would let an attacker perform a birthday attack.

How?  Assume the attacker knows a SHA-1 that has two different
data streams.  He knows the client is likely to have the "good"
one.  So he sends the "evil" variant to the other end as part of
a "large-ish" packfile.  The recipient keeps that packfile, and
indexes it.  Now since this is a birthday attack there is a SHA-1
collision; two objects exist in the repository with the same SHA-1.
They have *very* different data streams.  One of them is "evil".

Currently the poor recipient cannot tell the two objects apart,
short of by examining the timestamp of the packfiles.  But lets
say the recipient repacks before he realizes he's been attacked.
We may wind up packing the "evil" version of the object, and deleting
the "good" one.  This is made *even more likely* by Junio's recent
rearrange_packed_git patch (b867092f).

It is extremely unlikely for a SHA1 collisions to occur, but if it
ever happens with a remote (hence untrusted) object we simply must
not let the fetch succeed.

Normally received packs should not contain objects we already have.
But when they do we must ensure duplicated objects with the same SHA1
actually contain the same data.

9debc3241b git-fetch, git-branch: Support local --track via a special remote '.'
This patch adds support for a dummy remote '.' to avoid having
to declare a fake remote like

        [remote "local"]
                url = .
                fetch = refs/heads/*:refs/heads/*

Such a builtin remote simplifies the operation of "git-fetch",
which will populate FETCH_HEAD but will not pretend that two
repositories are in use, will not create a thin pack, and will
not perform any useless remapping of names.  The speed
improvement is around 20%, and it should improve more if
"git-fetch" is converted to a builtin.

To this end, git-parse-remote is grown with a new kind of
remote, 'builtin'.  In git-fetch.sh, we treat the builtin remote
specially in that it needs no pack/store operations.  In fact,
doing git-fetch on a builtin remote will simply populate
FETCH_HEAD appropriately.

The patch also improves of the --track/--no-track support,
extending it so that branch.<name>.remote items referring '.'
can be created.  Finally, it fixes a typo in git-checkout.sh.

87ab799234 builtin-mailinfo.c infrastrcture changes
I am working on a project that required parsing through regular
mboxes that didn't necessarily have patches embedded in them.  I
started by creating my own modified copy of git-am and working
from there.  Very quickly, I noticed git-mailinfo wasn't able to
handle a big chunk of my email.

After hacking up numerous solutions and running into more
limitations, I decided it was just easier to rewrite a big chunk
of it.  The following patch has a bunch of fixes and features
that I needed in order for me do what I wanted.

Note: I'm didn't follow any email rfc papers but I don't think
any of the changes I did required much knowledge (besides the
boundary stuff).

List of major changes/fixes:
- can't create empty patch files fix
- empty patch files don't fail, this failure will come inside git-am
- multipart boundaries are now handled
- only output inbody headers if a patch exists otherwise assume those
headers are part of the reply and instead output the original headers
- decode and filter base64 patches correctly
- various other accidental fixes

I believe I didn't break any existing functionality or
compatibility (other than what I describe above, which is really
only the empty patch file).

I tested this through various mailing list archives and
everything seemed to parse correctly (a couple thousand emails).

[jc: squashed in another patch from Don's five patch series to
 fix the test case, as this patch exposes the bug in the test.]

This is a simple test case that verifies fast-import keeps the tree
ordering correct after editing the same tree twice in a single

way the series handles sorting within the trees.

f43cd49fb8 Change {pre,post}-receive hooks to use stdin
Sergey Vlasov, Andy Parkins and Alex Riesen all pointed out that it
is possible for a single invocation of receive-pack to be given more
refs than the OS might allow us to pass as command line parameters
to a single hook invocation.

We don't want to break these up into multiple invocations (like
xargs might do) as that makes it impossible for the pre-receive
hook to verify multiple related ref updates occur at the same time,
and it makes it harder for post-receive to send out a single batch
notification.

Instead we pass the reference data on a pipe connected to the
hook's stdin, supplying one ref per line to the hook.  This way a
single hook invocation can obtain an infinite amount of ref data,
without bumping into any operating system limits.

0746d19a82 git-branch, git-checkout: autosetup for remote branch tracking
In order to track and build on top of a branch 'topic' you track from
your upstream repository, you often would end up doing this sequence:

  git checkout -b mytopic origin/topic
  git config --add branch.mytopic.remote origin
  git config --add branch.mytopic.merge refs/heads/topic

This would first fork your own 'mytopic' branch from the 'topic'
branch you track from the 'origin' repository; then it would set up two
configuration variables so that 'git pull' without parameters does the
right thing while you are on your own 'mytopic' branch.

This commit adds a --track option to git-branch, so that "git
branch --track mytopic origin/topic" performs the latter two actions
when creating your 'mytopic' branch.

If the configuration variable branch.autosetupmerge is set to true, you
do not have to pass the --track option explicitly; further patches in
this series allow setting the variable with a "git remote add" option.
The configuration variable is off by default, and there is a --no-track
option to countermand it even if the variable is set.

05ef58ec1f Teach receive-pack to run pre-receive/post-receive hooks
Bill Lear pointed out that it is easy to send out notifications of
changes with the update hook, but successful execution of the update
hook does not necessarily mean that the ref was actually updated.
Lock contention on the ref or being unable to append to the reflog
may prevent the ref from being changed.  Sending out notifications
prior to the ref actually changing is very misleading.

To help this situation I am introducing two new hooks to the
receive-pack flow: pre-receive and post-receive.  These new hooks
are invoked only once per receive-pack execution and are passed
three arguments per ref (refname, old-sha1, new-sha1).

The new post-receive hook is ideal for sending out notifications,
as it has the complete list of all refnames that were successfully
updated as well as the old and new SHA-1 values.  This allows more
interesting notifications to be sent.  Multiple ref updates could
be easily summarized into one email, for example.

The new pre-receive hook is ideal for logging update attempts, as it
is run only once for the entire receive-pack operation.  It can also
be used to verify multiple updates happen at once, e.g. an update
to the `maint` head must also be accompained by a new annotated tag.

Lots of documentation improvements for receive-pack are included
in this change, as we want to make sure the new hooks are clearly
explained.

8aaf7d6410 Refactor handling of error_string in receive-pack
I discovered we did not send an ng line in the report-status feedback
if the ref was not updated because the repository has the config
option receive.denyNonFastForwards enabled.  I think the reason this
happened is that it is simply too easy to forget to set error_string
when returning back a failure from update()

We now return an ng line for a non-fastforward update, which in
turn will cause send-pack to exit with a non-zero exit status.
Hence the modified test.

This refactoring changes update to return a const char* describing
the error, which execute_commands always loads into error_string.
The result is what I think is cleaner code, and allows us to
initialize the error_string member to NULL when we read_head_info.

I want error_string to be NULL in all commands before we call
execute_commands, so that we can reuse the run_hook function to
execute a new pre-receive hook.

78a8d641c1 Add core.symlinks to mark filesystems that do not support symbolic links.
Some file systems that can host git repositories and their working copies
do not support symbolic links. But then if the repository contains a symbolic
link, it is impossible to check out the working copy.

This patch enables partial support of symbolic links so that it is possible
to check out a working copy on such a file system.  A new flag
core.symlinks (which is true by default) can be set to false to indicate
that the filesystem does not support symbolic links. In this case, symbolic
links that exist in the trees are checked out as small plain files, and
checking in modifications of these files preserve the symlink property in
the database (as long as an entry exists in the index).

Of course, this does not magically make symbolic links work on such defective
file systems; hence, this solution does not help if the working copy relies
on that an entry is a real symbolic link.

When we read svm:source; make sure we correctly handle the '!'

from the virtual path within the repository.  We don't need
to make that distinction, honestly!

We also ensure that subdirectories are also mirrored with the
correct URL if we're using useSvmProps.

We have a new test that uses dumped repo that was really
created using SVN::Mirror to avoid ambiguities and
mis-understandings about the svm: properties.

Note: trailing whitespace in the svm.dump file is unfortunately
a reality and required by SVN; so please ignore it when applying
this patch.

Also, ensure that the -R/--remote/--svn-remote flag is always
in effect if explicitly passed via the command-line.  This
allows us to track logically different mirrors sharing the

  * correctly fetch when we only have branches and tags
    to glob from (no fetch keys defined)

dadc6d2a09 git-svn: allow 'init' to act as multi-init
multi-init is now just an alias that requires -T/-t/-b;
all options that 'init' can now accept.

This will hopefully simplify usage and reduce typing.

Also, allow the --shared option in 'init' to take an optional
argument now that 'git-init --shared' supports an optional
argument.

ccb6b6f5b5 t910*: s/repo-config/config/g; poke around possible race conditions
Some of the repo-config => config renaming missed the git-svn
tests; so I'm just renaming them to be consisten with the
rest of the modern git.

Also, some of the newer tests didn't have 'poke' in them
to workaround race conditions on fast machines.  This adds
places where they can _possibly_ occur; but I don't have
fast enough hardware to trigger them.

2edb9c5cf9 git-svn: make test for SVK mirror path import
A manual test that sets up a repository that looks like an SVK depot,
and then imports it to check that it looks like we mirrored the
'original' source.

There is also a minor modification to the git-svn test library shell
file which sets a variable for the subversion repository's filesystem
path.

[ew: made some of the tests stricter and more thorough]

26a62d57a2 git-svn: use separate, per-repository .rev_db files
We need a separate .rev_db file for each repository we're
tracking.  This allows us to track the same logical path off
multiple mirrors.  We preserve a symlink to the old .rev_db
(no-UUID) if we're (auto-)migrating from an old version to
preserve backwards compatibility.

Also, get rid of the uuid() wrapper since we cache UUID in our
private config, and the SVN::Ra::get_uuid() function memoizes
the return value per-connection.

74a81227f9 git-svn: correctly handle globs with a right-hand-side path component
Several bugs were found and fixed while getting this to work:

 * Remember the 'R'(eplace) case of actions and treat it like we
   would an 'A'(dd) case.

 * Fix a small case of follow-parent missing a parent if a
   subdirectory was modified in the revision where the parent was
   copied.

 * dirents returned by get_dir sometimes expire if the data
   structure is too big and the pool is destroyed, so we
   cache get_dir (along with check_path and get_revprops)
   temporarily along with its pool.
