8 years agorun-command: teach async threads to ignore SIGPIPE
Jeff 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.

8 years agosend-pack: close demux pipe before finishing async process
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
