bug#13840: OS X Emacs frequent crashes when files are open over FTP

[Silas S. Brown]

Hi, I'm getting frequent crashes on Mac OS 10.7.5 from:

  - GNU Emacs 24.2.1 downloaded from emacsformacosx.com
  - GNU Emacs 24.2.1 (Carbon) compiled from HomeBrew
  - GNU Emacs 24.1 downloaded from emacsformacosx.com
  - GNU Emacs 23.4 downloaded from emacsformacosx.com

  but not (so far) on GNU Emacs 23.2, which I'm hoping
  will be more stable on my system.  (Thanks for continuing
  to make the old builds available - useful in this situation.)

  (I have not tried 23.3.  After having trouble with the
   above versions, I started jumping back 2 at a time.
   So the problem may have been introduced in 23.3 or 23.4.)

Crashes especially when I have files open over FTP to my
Linux box, but I don't know if that's a red herring. 
(23.4 seems more likely to crash when opening a directory
in dired over sshfs, rather than FTP, but again I'm not
sure exactly what's causing the problem.  I am not able
to reliably reproduce the crash on demand.)

Emacs "beach-balls" for a few seconds and then disappears.
(Is there any kind of "kill Emacs if some critical
process takes too long" logic that might be kicking in?)

The bug might possibly be triggered by something in my
configuration (which I can't work without), these files
are available at http://people.ds.cam.ac.uk/ssb22/setup/emacs.tgz
(they refer to "xemacs" a lot because that's what I started
with, but I now use FSF Emacs).

Thanks.

Ouch, I just got a crash on 23.2 as well :-(

Just before this crash, I clicked on the "Buffers" menu.
I had 3 unsaved buffers at the time.

Will try 22.3 (may have to change my config).

bug#13840: 23.2 crashes as well

[Silas S. Brown]

Contrary to what I said in the original report, the
crash also happens on 23.2 (it occurred when I clicked
on the "Buffers" menu).

I'm now trying 22.3.

Please try the 24.3 pretest (aka 24.2.93), which you can find at
ftp://alpha.gnu.org/gnu/emacs/pretest/

I have no reason it won't crash, but at least we can try and track the
bug down in that release and try and get it fixed for 24.3.

For actual crashes, the most important thing is to run Emacs under
a debugger, so that when it crashes you can show us a backtrace.
Also it's important to use an Emacs that was compiled without
optimizations (-O0 or at worst -O1) so that the debugger has a maximum
of information.

Thanks.  It didn't take long to get a crash in 24.2.93 -
I just clicked on the "Help" menu!  Below is the (rather
long) backtrace (sorry if I didn't compile it with the
right options, I just did ./configure --with-ns and make
install as per the nextstep/README file).   Silas

bug#13840: Aquamacs also crashes

[Silas S. Brown]

For what it's worth, I've now confirmed that the crash
also affects Aquamacs 2.4 (in this case when I was visiting
a file via Ctrl-x Ctrl-f).

On http://people.ds.cam.ac.uk/ssb22/setup/emacs.html I
recommend Emacs 22 for now.

I forgot to mention that the file was on my Linux box which
I was connecting to via /ftp:192.168.... on find-file.

bug#13840: Fix for Emacs 24.3rc3 nextstep crash (menubar + ange-ftp + ns_select = emacs_abort)

[Silas S. Brown]

Hi, I do believe I've fixed it.  (but probably broke a
dozen GNU rules in the process ..  sorry ..  maybe a
real Emacs developer can do it properly?)  Patch below.

I downloaded emacs-24.3-rc3.tar.xz, did ./configure
--with-ns and then changed -O2 to -O0 in Makefile and
*/Makefile before running make install.  Then I ran
nextstep/Emacs.app/Contents/MacOS/Emacs inside gdb with
the -q flag (so it doesn't read my configuration), and
visited /ftp:192.168.0.3:/home/ssb22/wiki/WelcomePage (a
text file on my Linux box that opens in Fundamental mode).
Then if I click on the menu bar (Help, Buffers, etc) it
crashes immediately, reproducible every time.
An example backtrace is at the end of this email.

As far as I can tell, some code to populate the Buffers
menu is resulting in a call to verify_visited_file_modtime
on the FTP file.  This is calling the FTP process, which
results in a call to ns_select (in src/nsterm.m) during
the collection of FTP's output.  ns_select then calls
emacs_abort because ++apploopnr != 1.

The static variable 'apploopnr' is apparently designed
to make sure the [NSApp run] statements in
ns_read_socket and ns_select do not re-enter under any
circumstances.  I'm not familiar enough with Mac APIs to
understand exactly what "NSApp run" does, but I guess
the problem *might* be to do with the fact that we're
assuming we can't re-enter the API under any
circumstances but actually we're already in the API due
to handling a menubar click?  (just guessing.)

So I tried commenting out the 2 calls to emacs_abort in
ns_read_socket and ns_select.  Then when I click on the
menubar, it doesn't crash.  But the menus are all empty,
unless you first go into a non-FTP buffer and click the
menubar from there.

I then tried having the emacs_abort calls commented out
but DON'T run NSApp under these circumstances, i.e. I did:

  if (++apploopnr != 1) {} // do nothing
  else
  [NSApp run];

and this time it seemed the menus were less likely to be
empty, but there was still a certain probability that a
menu would be empty, unless you first click the menubar
from a non-FTP buffer.

Finally, I tried going back earlier in the ns_select
function, to the part that says:

  if (NSApp == nil
      || (timeout && timeout->tv_sec == 0 && timeout->tv_nsec == 0))
    return pselect (nfds, readfds, writefds, exceptfds, timeout, sigmask);

and I added " || apploopnr != 0" after NSApp == nil. 
(In other words, if apploopnr is wrong then just delegate
to POSIX pselect and ignore the timeout, it's better than
crashing.)  Then all the menus started working perfectly
and with no crashes so far.

So, my fix is the following patch (I just did "diff -u",
sorry if I should have done something else) -

---------- cut here --------------------------------

This is sort-of "cargo cult programming" because I don't
100% understand what I'm doing.  But I hope it will at
least give an Emacs developer an idea.
I've added a couple of emails from the top of nsterm.m
to the CC list; sorry if that was the wrong thing to do.
(How am I supposed to say "hey I've got a patch now"?)
I really hope this issue can be fixed in time for 24.3.

Thanks.     Silas
