git-grep: don't use sscanf
If you use scanf or sscanf to parse integers, your code probably
accepts bogus inputs. For example, builtin-grep (aka git-grep) uses
sscanf(scan, "%u", &num) to parse the integer argument to -A, -B, -C.
Currently, "-C 1,000" and "-C 4294967297" are both treated just like
"-C 1":
$ git-grep -h -C 4294967297 juggle
out and you may find it easier to switch back and forth if you
juggle multiple lines of development simultaneously. Of
course, you will pay the price of more disk usage to hold
The obvious fix is to use strtoul instead. But using a bare strtoul is
too messy, at least when done properly, so I've added a wrapper function.
The new function in the patch below belongs elsewhere if it would be
useful in replacing any of the four remaining uses of sscanf.
One final note: With this change, I get a slightly different
diagnostic depending on the context size:
$ ./git-grep -h -C 4294967296 juggle
fatal: 4294967296: invalid context length argument
[Exit 128]
$ ./git-grep -h -C 4294967295 juggle
grep: 4294967295: invalid context length argument
[Exit 1]
A common convention that makes it easy to identify the source
of a diagnostic is to include the program name before the first ":".
Whether that should be "git" or "git-grep" is another question.
Using "grep" or "fatal" is misleading.

shortlog: prompt when reading from terminal by mistake
I was trying to see who have been active recently to find GSoC
mentor candidates by running:
$ git shortlog -s -n --since=4.months | head -n 20
After waiting for about 20 seconds, I started getting worried,
thinking that the recent revision traversal updates might have
had an unintended side effect.
Not so. "git shortlog" acts as a filter when no revs are given,
unlike "git log" which defaults to HEAD. It was reading from

fast-import: grow tree storage more aggressively
When building up a tree for a commit, fast-import
dynamically allocates memory for the tree entries. When more
space is needed, the allocated memory is increased by a
constant amount. For very large trees, this means
re-allocating and memcpy()ing the memory O(n) times.
To compound this problem, releasing the previous tree
resource does not free the memory; it is kept in a pool
for future trees. This means that each of the O(n)
allocations will consume increasing amounts of memory,
giving O(n^2) memory consumption.

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.

Start defining a more sophisticated run_command
There are a number of places where we do some variation of
fork()+exec() but we also need to setup redirection in the process,
much like what run_command does for us already with its option flags.
It would be nice to reuse more of the run_command logic, especially
as that non-fork API helps us to port to odd platforms like Win32.

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.

gitlink:git-term[1]
it doesn't replace any occurence of "term" preceded by "link:git-".
This fails for gitlink:git-symbolic-ref[1] when substituting for "ref".
So instead just refuse to replace anything preceded by a "-".
That could result in missing some opportunities, but that's a less

git-bundle: Make thin packs
Thin packs are way smaller, but they rely on the receiving end to have the
base objects. However, Git's pack protocol also uses thin packs by
default. So make the packs contained in bundles thin, since bundles are
just another transport.
The patch looks a bit bigger than intended, mainly because --thin
_implies_ that pack-objects should run its own rev-list. Therefore, this
patch removes all the stuff we used to roll rev-list ourselves.
This commit also changes behaviour slightly: since we now know early
enough if a specified ref is _not_ contained in the pack, we can avoid
putting that ref into the pack. So, we don't die() here, but warn()
instead, and skip that ref.

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.

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.

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.

This is a simple refactoring of run_update_hook to allow the function
to be passed the name of the hook it runs and also to build the

Preallocate memory earlier in fast-import
I'm about to teach fast-import how to reload the marks file created
by a prior session. The general approach that I want to use is to
immediately parse the marks file when the specific argument is found
in argv, thereby allowing the caller to supply multiple marks files,
as the mark space can be sparsely populated.
To make that work out we need to allocate our object tables before
we parse the command line options. Since none of these tables
depend on the command line options, we can easily relocate them.

Cast 64 bit off_t to 32 bit size_t
Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4.
This implies that we are able to access and work on files whose
maximum length is around 2^63-1 bytes, but we can only malloc or
mmap somewhat less than 2^32-1 bytes of memory.
On such a system an implicit conversion of off_t to size_t can cause
the size_t to wrap, resulting in unexpected and exciting behavior.
Right now we are working around all gcc warnings generated by the
-Wshorten-64-to-32 option by passing the off_t through xsize_t().
In the future we should make xsize_t on such problematic platforms
detect the wrapping and die if such a file is accessed.

This change does not modify everything in pack-objects that probably
needs to change to fully support the maximum of 2**32-1 objects.
I'm intentionally breaking the improvements into slightly smaller

General const correctness fixes
We shouldn't attempt to assign constant strings into char*, as the
string is not writable at runtime. Likewise we should always be
treating unsigned values as unsigned values, not as signed values.
Most of these are very straightforward. The only exception is the
(unnecessary) xstrdup/free in builtin-branch.c for the detached
head case. Since this is a user-level interactive type program
and that particular code path is executed no more than once, I feel
that the extra xstrdup call is well worth the easy elimination of
this warning.

git-archimport: allow remapping branch names
This patch adds support to archimport for remapping the branch
names to match those used in git more closely. This is useful
for projects that migrate to git (as opposed to users that want
to use git on Arch-based projects). For example, one can choose
an Arch branch name and call it "master".
The new command-line syntax works even if there is a colon in
a branch name, since only the part after the last colon is taken
to be the git name (git does not allow colons in branch names).
The new feature is implemented so that archives rotated every
year can also be remapped into a single git archive.

gitweb: Don't escape attributes in CGI.pm HTML methods
There is no need to escape HTML tag's attributes in CGI.pm
HTML methods (like CGI::a()), because CGI.pm does attribute
escaping automatically.
$cgi->a({ ... -attribute => atribute_value }, tag_contents)

<a ... attribute="attribute_value">tag_contents</a>
The rules for escaping attribute values (which are string contents) are
different. For example you have to take care about escaping embedded '"'
and "'" characters; CGI::a() does that for us automatically.
CGI::a() does not HTML escape tag_contents; we would need to write
<a href="URL">some <b>bold</b> text</a>
for example. So we use esc_html (or esc_path) to escape tag_contents
as needed.
