Commit 09c9957c fixes a deadlock in which pack-objects
fails, the remote end is still waiting for pack data, and we
are still waiting for the remote end to say something (see
that commit for a much more in-depth explanation).
We solved the problem there by making sure the output pipe
is closed on error; thus the remote sees EOF, and proceeds
to complain and close its end of the connection.
However, in the special case of push over git://, we don't
have a pipe, but rather a full-duplex socket, with another
dup()-ed descriptor in place of the second half of the pipe.
In this case, closing the second descriptor signals nothing
to the remote end, and we still deadlock.
This patch calls shutdown() explicitly to signal EOF to the
other side.

They might care because they want to do a half-duplex close.
With pipes, that means simply closing the output descriptor;
with a socket, you must actually call shutdown.
Instead of exposing the magic no_fork child_process struct,
let's encapsulate the test in a function.

The git_connect function returns two ends of a pipe for
talking with a remote, plus a struct child_process
representing the other end of the pipe. If we have a direct
socket connection, then this points to a special "no_fork"
child process.
The code path for doing git-over-pipes or git-over-ssh sets
up this child process to point to the child git command or
the ssh process. When we call finish_connect eventually, we
check wait() on the command and report its return value.
The code path for git://, on the other hand, always sets it
to no_fork. In the case of a direct TCP connection, this
makes sense; we have no child process. But in the case of a
proxy command (configured by core.gitproxy), we do have a
child process, but we throw away its pid, and therefore
ignore its return code.
Instead, let's keep that information in the proxy case, and
respect its return code, which can help catch some errors
(though depending on your proxy command, it will be errors
reported by the proxy command itself, and not propagated
from git commands. Still, it is probably better to propagate
such errors than to ignore them).
It also means that the child_process field can reliably be
used to determine whether the returned descriptors are
actually a full-duplex socket, which means we should be
using shutdown() instead of a simple close.

The merge-recursive strategy already handles root commits;
it cherry-picks the difference between the empty tree and

However, for external strategies, we dereference NULL and
segfault while building the argument list. Instead, let's
handle this by passing the empty tree sha1 to the merge
script.

When the command line has "--" disambiguator, we take the remainder of

we need to append to the existing prune_data and end up attempting to
realloc(3) it. That would not work.

The zsh support of git-completion script in contrib/ is broken for current
versions of zsh, and does not notice when there's a subcommand.
For example: "git log origi<TAB>" gives no completions because it would
try to find a "git origi..." command. This will be fixed by zsh 4.3.12,
but for now we can workaround it by backporting the same fix as zsh folks
implemented.
The problem started after commit v1.7.4-rc0~11^2~2 (bash: get
--pretty=m<tab> completion to work with bash v4), which introduced
_get_comp_words_by_ref() that comes from bash-completion[1] scripts, and
relies on the 'words' variable.
However, it turns out 'words' is a special variable used by zsh
completion. From zshcompwid(1):
[...] the parameters are reset on each function exit (including nested
function calls from within the completion widget) to the values they had
when the function was entered.
As a result, subcommand words are lost. Ouch.
This is now fixed in the latest master branch of zsh[2] by simply defining
'words' as hidden (typeset -h), which removes the special meaning inside
the emulated bash function. So let's do the same.
Jonathan Nieder helped on the commit message.

Notice that the prefix specified for the build influenced the definitions
of ETC_GITCONFIG and ETC_GITATTRIBUTES only when it was exactly '/usr'.
Kacper Kornet noticed that this was furthermore only the case when the
build was triggered using 'make prefix=/usr', i.e., the prefix was given
on the command line; it did not work when the prefix was specified in
config.mak because this file is included much later in the Makefile.
To fix this, move the conditional after the inclusion of config.mak.
Additionally, it is desirable to specify the etc directory for a build
(for example, a build with prefix /usr/local may still want to have the
system configuration in /etc/gitconfig). For this purpose, promote the
variable 'sysconfdir' from a helper variable to a configuration
variable. The prefix check that was moved must now be wrapped so that it
does not override sysconfdir setting given in config.mak.

Kacper Kornet noticed that a $variable in "word" in the above construct is
not substituted by his pdksh. Modern POSIX compliant shells (e.g. dash,
ksh, bash) all seem to interpret POSIX "2.6.2 Parameter Expansion" that
says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.
Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at
length at the Austin group. We can avoid this issue and future-proof the
test by a slight rewrite.

Since c0cb4ed (git-instaweb: Configure it to work with new gitweb
structure, 2010-05-28) git-instaweb does not re-create gitweb.cgi
etc., but makes use of installed gitweb. Therefore simplify
git-instaweb dependency on gitweb subsystem in main Makefile from
'gitweb/gitweb.cgi gitweb/static/gitweb.css gitweb/static/gitweb.js'
to simply 'gitweb'.
This is preparation for splitting gitweb.perl script, and for
splitting gitweb.js (to be reassembled / combined on build). This way
we don't have to duplicate parts of gitweb/Makefile in main
Makefile... it is also more correct description of git-instaweb

The parsing of the additional command line parameters supplied to
the branch.<name>.mergeoptions configuration variable was implemented
at the wrong stage. If any merge-related variable came after we read
branch.<name>.mergeoptions, the earlier value was overwritten.
We should first read all the merge.* configuration, override them by
reading from branch.<name>.mergeoptions and then finally read from
the command line.
This patch should fix it, even though I now strongly suspect that
branch.<name>.mergeoptions that gives a single command line that
needs to be parsed was likely to be an ill-conceived idea to begin
with. Sigh...

Commit 09c9957 (send-pack: avoid deadlock when pack-object
dies early, 2011-04-25) attempted to fix a hang in the
stateless rpc case by closing a file descriptor early, but
we still need that descriptor.
Basically the deadlock can happen when pack-objects fails,
and the descriptor to upstream is left open. We never send
the pack, so the upstream is left waiting for us to say
something, and we are left waiting for upstream to close the
connection.
In the non-rpc case, our descriptor points straight to the
upstream. We hand it off to run-command, which takes
ownership and closes the descriptor after pack-objects
finishes (whether it succeeds or not).
Commit 09c9957 tried to emulate that in the rpc case. That
isn't right, though. We actually have a descriptor going
back to the remote-helper, and we need to keep using it
after pack-objects is finished. Closing it early completely
breaks pushing via smart-http.
We still need to do something on error to signal the
remote-helper that we won't be sending any pack data
(otherwise we get the deadlock). In an ideal world, we
would send a special packet back that says "Sorry, there was
an error". But the remote-helper doesn't understand any such
packet, so the best we can do is close the descriptor and
let it report that we hung up unexpectedly.
