(This bug may be related to some quirkyness around external
subprocesses, such as those started by flymake or archive-mode.  These
sometimes don't run properly, but I haven't been able to pin that one
down at all.  They do cause a dialog box, e.g., indicating that a
program is not found which is very much there.  This in turn may be
related to a bug where Emacs still thinks it has subprocesses attached
to a buffer that is to be killed.  All very confusing.  On to this bug:)

Approximately the second dialog box that Emacs displays because of the
above quirkyness gets stuck in the following way:

The dialog box is not displayed, but Emacs also no longer accepts any
input on the existing frames.  Looking at it in the debugger suggests
that there should indeed be a dialog box visible:

^C
Program received signal SIGINT, Interrupt.
0x00007fff876399ee in __semwait_signal ()
(gdb) where
#0  0x00007fff876399ee in __semwait_signal ()
#1  0x00007fff8763987d in nanosleep ()
#2  0x00007fff88a5677c in +[NSThread sleepUntilDate:] ()
#3  0x00000001001a5b87 in -[EmacsDialogPanel runDialogAt:] ()
#4  0x003a657461446c69 in ?? ()

This is as good as a crash as there is no way to supply any further
input to the running Emacs.
(Obviously, I restarted Emacs to type this bug report.)

Hello Carsten,

Thank you for this test case.  I tried the procedure outlined, but could not reproduce the issue on a somewhat older (23.1.90) version of emacs, running 64-bit on 10.6.2.  I guess we have a regression here.  However, I fixed a related dialog problem (bug#5811) with the attached patch.  Would you be able to test it and see if it does anything for the issue in your case?

thanks,
Adrian

I just tried rebuilding Emacs 24.0. from scratch, from the git version 218181d7f636089824e9f876a5d662bf2e350229.
Using the parameters you told me:

setenv CFLAGS '-g'
./configure --with-ns
make -j3
make install

Running this on 10.6.3 (but I previously reproduced this on 10.6.2).

Now it takes three attempts (not two as previously) to open a Ruby file to reproduce the bug.
(This appears to point to some randomness influencing the occurrence of the bug.)


> I guess we have a regression here.  However, I fixed a related dialog problem (bug#5811) with the attached patch.  Would you be able to test it and see if it does anything for the issue in your case?

I then applied the patch, rebuilt (make -j3; make install), and retried.
(I cannot reproduce 5811 with the patched version, but I didn't try before patching; I *can* reproduce 5811 with an earlier 24.0.50 from http://emacsformacosx.com/builds -- the one built 2010-03-30; so this bug now seems to be fixed.)

Unfortunately, the patch makes no difference in the behavior wrt 5515.

BTW, if I evoke the print dialog once (CMD-P), click No, and then try the C-x C-f, I need only two attempts to trigger the bug.  If I evoke the print dialog twice, click No, and then try the C-x C-f, I trigger the bug immediately.  So it looks like the third dialog gets hit, but:
I can evoke the print dialog as much as I want without triggering the bug.

So, it looks like:
-- the bug only happens if dialogs have been active before (used to be once, now twice).
-- the bug only happens if the dialog is evoked in some rather specific circumstances (such as here: from an error handler in the creation of a process that is started from a timer handler).

Looks like this needs more work to properly isolate.

Gruesse, Carsten

Thanks, I'm able to reproduce it -- hitting the C-x C-v a second time as you say did the trick.

I'll try to fix it when I get a chance.

BTW, a couple of other comments re: interaction with the print dialog.  With me, the print dialog seems to help things.  If I do the first bad-find-ruby-file, then a Cmd-P, then I can do any number of bad-find-ruby-files without issue.  I don't know why.  Also, the behavior seems 100% deterministic in my case -- same patterns will always lead to the "nirvana" state.  Something inside the state of emacs / NS's event handling has changed, but I have not been able to isolate what.

I can't reproduce this in Emacs 25, so I'm guessing it got fixed a while
back.

I'll close this bug.
