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.

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.

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.]

The Git tree sorting convention is more complex than just the name,
it needs to include the mode too to make sure trees sort as though
their name ends with "/".
This is a simple test case that verifies fast-import keeps the tree

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.

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.

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.

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.

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.
