12 years, 10 months
Vin Shelton
Aidan -
Here is your patch with a ChangeLog supplied. If I hear no objection
within the next couple of days, I will apply this patch to both 21.4
and 21.5.
Thanks,
Vin

[AC 21.5] Prevent SIGPIPE in deactivate_process
12 years, 11 months
Stephen J. Turnbull
APPROVE COMMIT 21.5
I don't know if this is relevant to 21.4. Should I check, Vin? This
seems to be a very rare crash, up until Uday Reddy and friends found
me a way to produce it frequently. :-)
Reviewers: If you have a clue about Unix processes, please check my
analysis below, especially with respect to the call of
deactivate_process() in execute_internal_event() (event-stream.c).
VM seems to have replaced Gnus as my favorite way to induce XEmacs
crashes.... VM uses Imagemagick's convert program to generate
thumbnails to display with its MIME buttons, and apparently convert
crashes a lot. When this happens, there's a race condition such that
send_process() thinks it has blocked but doesn't know about the crash,
and so calls Faccept_process_output() in hopes of getting the subprocess
unblocked. The SIGCHLD arrives in the interim, status_notify() gets
called inside of Faccept_process_output(), notices the demise of the
child, and calls deactivate_process(), which tries to do a normal close
of all pipes. That calls Lstream_flush(), which writes to the now
nonexistent output pipe, and XEmacs takes the fall because it's not
prepared for a SIGPIPE there.
An analysis of calls of deactivate_process() indicates that it only gets
called when we know the process has already exited, so it makes no
sense to flush the output pipe. This patch removes the flush from the
function closing the output pipe (only).
I would like to do the signal(2) dance in the relevant Lstream
implementation (filedesc), but it doesn't know about pipes and
processes, only about FDs. Is it worth creating a pipe-specific
variant of the filedesc Lstream?
I will revert this patch on request. I don't really have an idea of
what bad things could happen if we fail to flush to a live process
that is about to be terminated, but if somebody thinks that's a risk,
I have an alternative patch which reduces the current risk but does
not eliminate it. (Specifically, with the alternative patch, the race
condition still exists in Faccept_process_output(), which is a Lisp
function so we have no idea when it might be called.)

Give the label name when warning or erroring, bytecomp.el
2011-11-02 Aidan Kehoe <kehoea(a)parhasard.net>
* bytecomp.el (byte-compile-lambda):
Accept a new NAME argument here, have byte-compile-current-form
reflect that if it's specified.
* bytecomp.el (byte-compile-initial-macro-environment):
Specify the label name when byte-compiling it, so warning and
errors are more helpful.

‘Iodine deficiency was endemic in parts of the UK until, through what has been
described as “an unplanned and accidental public health triumph”, iodine was
added to cattle feed to improve milk production in the 1930s.’
