verify-tag: prepare verify_tag for libification

The current interface of verify_tag() resolves reference names to SHA1,
however, the plan is to make this functionality public and the current
interface is cumbersome for callers: they are expected to supply the
textual representation of a sha1/refname. In many cases, this requires
them to turn the sha1 to hex representation, just to be converted back
inside verify_tag.

Add a SHA1 parameter to use instead of the name parameter, and rename
the name parameter to "name_to_report" for reporting purposes only.

We could add the same option to "git pull" and have it passed

opposition against such a feature, but this commit does not do
so and instead leaves it as low-hanging fruit for others,
because such a "two project merge" would be done after fetching
the other project into some location in the working tree of an

is sufficient to allow a local merge without such an option

all the later references are for the tag, there is no reason for the

In commit 9ff18fa (fetch-pack: ignore SIGPIPE in sideband

ignore SIGPIPE in the async demuxer thread. However, this is
rather clumsy, as it ignores SIGPIPE for the entire process,
including the main thread. At the time we didn't have any
per-thread signal support, but we now we do. Let's use it.

send-pack: isolate sigpipe in demuxer thread

If we get an error from pack-objects, we may exit
send_pack() early, before reading the server's status
response. In such a case, we may racily see SIGPIPE from our
async demuxer (which is trying to write that status back to
us), and we'd prefer to continue pushing the error up the
call stack, rather than taking down the whole process with
signal death.

This is safe to do because our demuxer just calls
recv_sideband, whose data writes are all done with
write_or_die(), which will notice SIGPIPE.

We do also write sideband 2 to stderr, and we would no
longer die on SIGPIPE there (if it were piped in the first
place, and if the piped program went away). But that's
probably a good thing, as it likewise should not abort the
push process at all (neither immediately by signal, nor
eventually by reporting failure back to the main thread).

run-command: teach async threads to ignore SIGPIPEJeff King Tue, 19 Apr 2016 22:49:41 +0000 (18:49 -0400)

run-command: teach async threads to ignore SIGPIPE

Async processes can be implemented as separate forked
processes, or as threads (depending on the NO_PTHREADS
setting). In the latter case, if an async thread gets
SIGPIPE, it takes down the whole process. This is obviously
bad if the main process was not otherwise going to die, but
even if we were going to die, it means the main process does
not have a chance to report a useful error message.

There's also the small matter that forked async processes
will not take the main process down on a signal, meaning git
will behave differently depending on the NO_PTHREADS
setting.

This patch fixes it by adding a new flag to "struct async"
to block SIGPIPE just in the async thread. In theory, this
should always be on (which makes async threads behave more
like async processes), but we would first want to make sure
that each async process we spawn is careful about checking
return codes from write() and would not spew endlessly into
a dead pipe. So let's start with it as optional, and we can
enable it for specific sites in future patches.

The natural name for this option would be "ignore_sigpipe",
since that's what it does for the threaded case. But since
that name might imply that we are ignoring it in all cases
(including the separate-process one), let's call it
"isolate_sigpipe". What we are really asking for is
isolation. I.e., not to have our main process taken down by
signals spawned by the async process. How that is
implemented is up to the run-command code.

send-pack: close demux pipe before finishing async... Jeff King Tue, 19 Apr 2016 22:45:17 +0000 (18:45 -0400)

send-pack: close demux pipe before finishing async process

This fixes a deadlock on the client side when pushing a
large number of refs from a corrupted repo. There's a
reproduction script below, but let's start with a
human-readable explanation.

The client side of a push goes something like this:

1. Start an async process to demux sideband coming from
the server.

2. Run pack-objects to send the actual pack, and wait for
its status via finish_command().

3. If pack-objects failed, abort immediately.

4. If pack-objects succeeded, read the per-ref status from
the server, which is actually coming over a pipe from
the demux process started in step 1.

We run finish_async() to wait for and clean up the demux
process in two places. In step 3, if we see an error, we
want it to end early. And after step 4, it should be done
writing any data and we are just cleaning it up.

Let's focus on the error case first. We hand the output
descriptor to the server over to pack-objects. So by the
time it has returned an error to us, it has closed the
descriptor and the server has gotten EOF. The server will
mark all refs as failed with "unpacker error" and send us
back the status for each (followed by EOF).

This status goes to the demuxer thread, which relays it over
a pipe to the main thread. But the main thread never even
tries reading the status. It's trying to bail because of the
pack-objects error, and is waiting for the demuxer thread to
finish. If there are a small number of refs, that's OK; the
demuxer thread writes into the pipe buffer, sees EOF from
the server, and quits. But if there are a large number of
refs, it may block on write() back to the main thread,
leading to a deadlock (the main thread is waiting for the
demuxer to finish, the demuxer is waiting for the main
thread to read).

We can break this deadlock by closing the pipe between the
demuxer and the main thread before calling finish_async().
Then the demuxer gets a write() error and exits.

The non-error case usually just works, because we will have
read all of the data from the other side. We do close
demux.out already, but we only do so _after_ calling
finish_async(). This is OK because there shouldn't be any
more data coming from the server. But technically we've only
read to a flush packet, and a broken or malicious server
could be sending more cruft. In such a case, we would hit
the same deadlock. Closing the pipe first doesn't affect the
normal case, and means that for a cruft-sending server,
we'll notice a write() error rather than deadlocking.

Note that when write() sees this error, we'll actually
deliver SIGPIPE to the thread, which will take down the
whole process (unless we're compiled with NO_PTHREADS). This
isn't ideal, but it's an improvement over the status quo,
which is deadlocking. And SIGPIPE handling in async threads
is a bigger problem that we can deal with separately.

A simple reproduction for the error case is below. It's
technically racy (we could exit the main process and take
down the async thread with us before it even reads the
status), though in practice it seems to fail pretty
consistently.

git init repo &&
cd repo &&

# make some commits; we need two so we can simulate corruption
# in the history later.
git commit --allow-empty -m one &&
one=$(git rev-parse HEAD) &&
git commit --allow-empty -m two &&
two=$(git rev-parse HEAD) &&

# now make a ton of refs; our goal here is to overflow the pipe buffer
# when reporting the ref status, which will cause the demuxer to block
# on write()
for i in $(seq 20000); do
echo "create refs/heads/this-is-a-really-long-branch-name-$i $two"
done |
git update-ref --stdin &&

# now make a corruption in the history such that pack-objects will fail
rm -vf .git/objects/$(echo $one | sed 's}..}&/}') &&

# and then push the result
git init --bare dst.git &&
git push --mirror dst.git

mv: allow moving nested submodulesStefan Beller Tue, 19 Apr 2016 18:32:04 +0000 (11:32 -0700)

mv: allow moving nested submodules

When directories are moved using `git mv` all files in the directory
have been just moved, but no further action was taken on them. This
was done by assigning the mode = WORKING_DIRECTORY to the files
inside a moved directory.

submodules however need to update their link to the git directory as
well as updates to the .gitmodules file. By removing the condition of
`mode != INDEX` (the remaining modes are BOTH and WORKING_DIRECTORY) for
the required submodule actions, we perform these for submodules in a
moved directory.

The part that removes object files in the 'clean' target predates
various Makefile macros that list object files we create, and
instead removes the objects with shell glob, perpetually requiring

Simplify the target by removing $(OBJECTS), which is supposed to
