send-pack: avoid deadlock on git:// push with failed pack-objects

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.

connect: treat generic proxy processes like ssh processes

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.

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.

send-pack: avoid deadlock when pack-object dies early

Send-pack deadlocks in two ways when pack-object dies early (for example,
because there is some repo corruption).

The first deadlock happens with the smart push protocol (--stateless-rpc).
After the initial rev-exchange, the remote is waiting for the pack data
to arrive, and the sideband demuxer at the local side continues trying to
stream data from the remote repository until it gets EOF. Meanwhile,
send-pack (in function pack_objects()) has noticed that pack-objects did
not produce output and died. Back in send_pack(), it now tries to clean
up the sideband demuxer using finish_async(). The demuxer, however, waits
for the remote end to close down, the remote waits for pack data, and
the reason that it still waits is that send-pack forgot to close the
outgoing channel. Add the missing close() in pack_objects().

The second deadlock happens in a similar constellation when the sideband
demuxer runs in a forked process (rather than in a thread). Again, the
remote end waits for pack data to arrive, the sideband demuxer waits for
the remote to shut down, and send-pack (in the regular clean-up) waits for
the demuxer to terminate. This time, the send-pack parent process closes
the writable end of the outgoing channel (in start_command() that spawned
pack-objects) so that after the death of the pack-objects process all
writable ends should have been closed and the remote repo should see EOF.
This does not happen, however, because when the sideband demuxer was forked
earlier, it also inherited a writable end; it remains open and keeps the
remote repo from seeing EOF. To break this deadlock, close the writable end
in the demuxer.

Jeff King [Wed, 6 Apr 2011 21:33:33 +0000 (17:33 -0400)]
upload-pack: start pack-objects before async rev-list

In a pthread-enabled version of upload-pack, there's a race condition
that can cause a deadlock on the fflush(NULL) we call from run-command.

What happens is this:

  1. Upload-pack is informed we are doing a shallow clone.

  2. We call start_async() to spawn a thread that will generate rev-list
     results to feed to pack-objects. It gets a file descriptor to a
     pipe which will eventually hook to pack-objects.

  3. The rev-list thread uses fdopen to create a new output stream
     around the fd we gave it, called pack_pipe.

  4. The thread writes results to pack_pipe. Outside of our control,
     libc is doing locking on the stream. We keep writing until the OS
     pipe buffer is full, and then we block in write(), still holding
     the lock.

  5. The main thread now uses start_command to spawn pack-objects.
     Before forking, it calls fflush(NULL) to flush every stdio output
     buffer. It blocks trying to get the lock on pack_pipe.

And we have a deadlock. The thread will block until somebody starts
reading from the pipe. But nobody will read from the pipe until we
finish flushing to the pipe.

To fix this, we swap the start order: we start the
pack-objects reader first, and then the rev-list writer
after. Thus the problematic fflush(NULL) happens before we
even open the new file descriptor (and even if it didn't,
flushing should no longer block, as the reader at the end of
the pipe is now active).

Jonathan Nieder [Fri, 18 Mar 2011 20:23:52 +0000 (15:23 -0500)]
compat: add missing #include <sys/resource.h>

Starting with commit c793430 (Limit file descriptors used by packs,
2011-02-28), git uses getrlimit to tell how many file descriptors it
can use.  Unfortunately it does not include the header declaring that
function, resulting in compilation errors:

 sha1_file.c: In function 'open_packed_git_1':
 sha1_file.c:718: error: storage size of 'lim' isn't known
 sha1_file.c:721: warning: implicit declaration of function 'getrlimit'
 sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function)
 sha1_file.c:718: warning: unused variable 'lim'

The standard header to include for this is <sys/resource.h> (which on
some systems itself requires declarations from <sys/types.h> or
<sys/time.h>).  Probably the problem was missed until now because in
current glibc sys/resource.h happens to be included by sys/wait.h.

MinGW does not provide sys/resource.h (and compat/mingw takes care of
providing getrlimit some other way), so add the missing #include to
the "#ifndef __MINGW32__" block in git-compat-util.h.

Nicolas Morey-Chaisemartin [Wed, 30 Mar 2011 05:20:02 +0000 (07:20 +0200)]
submodule: process conflicting submodules only once

During a merge module_list returns conflicting submodules several times
(stage 1,2,3) which caused the submodules to be used multiple times in
git submodule init, sync, update and status command.

There are 5 callers of module_list; they all read (mode, sha1, stage,
path) tuple, and most of them care only about path.  As a first level
approximation, it should be Ok (in the sense that it does not make things
worse than it currently is) to filter the duplicate paths from module_list
output, but some callers should change their behaviour when the merge in
the superproject still has conflicts.

Notice the higher-stage entries, and emit only one record from
module_list, but while doing so, mark the entry with "U" (not [0-3]) in
the $stage field and null out the SHA-1 part, as the object name for the
lowest stage does not give any useful information to the caller, and this
way any caller that uses the object name would hopefully barf.  Then
update the codepaths for each subcommands this way:

 - "update" should not touch the submodule repository, because we do not
   know what commit should be checked out yet.

 - "status" reports the conflicting submodules as 'U000...000' and does
   not recurse into them (we might later want to make it recurse).

 - The command called by "foreach" may want to do whatever it wants to do
   by noticing the merged status in the superproject itself, so feed the
   path to it from module_list as before, but only once per submodule.

 - "init" and "sync" are unlikely things to do while the superproject is
   still not merged, but as long as a submodule is there in $path, there
   is no point skipping it. It might however want to take the merged
   status of .gitmodules into account, but that is outside of the scope of
   this topic.

Fractional timezones, like -0330 (NST used in Canada) or +0430
(Afghanistan, Iran DST), were not handled properly in parse_date; this
means values such as 'minute_local' and 'iso-tz' were not generated
correctly.

This was caused by two mistakes:

* sign of timezone was applied only to hour part of offset, and not
  as it should be also to minutes part (this affected only negative
  fractional timezones).

* 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60',
  so fractional part was discarded altogether ($h is hours, $m is
  minutes, which is always less than 60).

Note that positive fractional timezones +0430, +0530 and +1030 can be
found as authortime in git.git repository itself.

For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime
of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked
with 'atnight', when "git show 88d50e7" gives correct author date of

stash: copy the index using --index-output instead of cp -p

'git stash create' must operate with a temporary index. For this purpose,
it used 'cp -p' to create a copy. -p is needed to preserve the timestamp
of the index file. Now Jakob Pfender reported a certain combination of
a Linux NFS client, OpenBSD NFS server, and cp implementation where this
operation failed.

Luckily, the first operation in git-stash after copying the index is to
call 'git read-tree'. Therefore, use --index-output instead of 'cp -p'
to write the copy of the index.

--index-output requires that the specified file is on the same volume as
the source index, so that the lock file can be rename()d. For this reason,
the name of the temporary index is constructed in a way different from the
other temporary files. The code path of 'stash -p' also needs a temporary
index, but we do not use the new name because it does not depend on the
same precondition as --index-output.

gitweb: highlight: replace tabs with spaces

Consider the following code fragment:

vim ":set list" mode shows that the first character on each line is a
tab:

^I/*$
^I * test$
^I */$

By default, the "highlight" program will retain the tabs in the HTML
output:

$ highlight --fragment --syntax c test.c
        <span class="hl com">/*</span>
<span class="hl com">    * test</span>

^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$

In gitweb, this winds up looking something like:

   1         /*
   2     * test
   3     */

I tried both Firefox and Opera and saw the same behavior.

The desired output is:

   1         /*

And it breaks out of the loop when it knows it already found any change.

Note that the f245194 (diff: change semantics of "ignore whitespace"
