When I start a debugging session with M-x gdb, initialization doesn't
appear to complete. I don't get the "(gdb)" prompt, and the mode line
continues to say "initializing". If I press Return, I get the prompt
and the mode line changes to "ready". Everything works fine after that.
This seems Cygwin-specific; it doesn't happen on GNU/Linux.
I've checked that all the strings that emacs sends to gdb during
initialization (via gdb-input) do in fact get sent. And I've tried
sending those same strings to gdb outside of emacs (except for
"-inferior-tty-set..."), and nothing strange happened. In particular, I
did have a "(gdb)" prompt at each stage.
Does anyone have any suggestions as to what might cause this or how I
can debug it? I don't have any experience with elisp debugging, so I
would appreciate a few pointers to help get me started.
Thanks.

Further info: It seems that initialization is actually completing, but
for some reason the buffer is not being redisplayed. To test this, I
inserted (sit-for .1) at the end of gdb-update to force redisplay, and
that solved the problem. Unless someone who understands redisplay can
figure out why redisplay isn't happening on Cygwin, I'm inclined to
apply the following patch:

My crystal ball says that redisplay isn't happening because Emacs
doesn't know that the GDB prompt has arrived. The call to sit-for
causes Emacs to check its input descriptors, "discovering" that there
is input.
Please look around in wait_reading_process_output, and see what is
going on there, before and after the call to sit-for. In particular,
does the call to `select' report that input has arrived from GDB?

I think it's not going to solve the real problem. If Emacs misses
some of the output arriving from GDB, it will miss it again under
similar circumstances.

Thanks for the suggestions, Eli. First of all, I was wrong when I said
that the problem was redisplay: using sleep-for instead of sit-for
works just as well. As your crystal ball predicted, the problem is that
emacs hasn't read its input from GDB. Here's what happens:
After M-x gdb finishes its initialization, emacs goes into its command
loop. read_char calls sit_for with a timeout of 30 seconds, and sit_for
calls wait_reading_process_output, which calls select. The call to
select fails immediately with EINTR. I don't understand the command
loop well enough to know what's interrupting the select call. But
select works fine in other settings (such as when I insert sleep-for in
the gdb initialization).
It seems that the problem is not really about M-x gdb, but about the
emacs command loop. I see the same kinds of select failures (always
with EINTR) if I just start up emacs and watch the calls to select
during the command loop.
The code in keyboard.c is full of alarms and timers, presumably related
to polling for keyboard input. Could this polling be doing something
that interrupts the select call under some circumstances?

EINTR means that some signal arrived (assuming that Cygwin's `select'
is Posix-ish enough). The question is, which signal? Does Cygwin
provide any tools to see which signals were delivered to a program?
Also, the fact that `select' is interrupted doesn't necessarily mean
that the input arrival is ignored, does it? Doesn't
wait_reading_process_output loop around and examines the input
descriptors again? If not, why not? IOW, why should EINTR become a
failure?

Atimers (those which are responsible for the "busy cursor" display)
could deliver SIGALRM, yes. But again, I don't see why this should
fail the loop that waits for input, and then only in this particular
case. Something else is at work here.

There's a program called strace that produces lots of debugging
information like this. I'll give it a try.

No, wait_reading_process_output treats EINTR as though it meant there's
no input available. Here's the relevant code from process.c, line 4638.
if (nfds < 0)
{
if (xerrno == EINTR)
no_avail = 1;
Even worse, xg_select (which is what the Cygwin build uses) deliberately
returns -1 and sets errno = EINTR whenever the actual select call
returns 0. Here's the code from xg_select.c, line 141:
/* To not have to recalculate timeout, return like this. */
if (retval == 0)
{
retval = -1;
errno = EINTR;
}
I don't know the rationale for treating EINTR the same as no input
available, but I agree that it doesn't seem right.

Which is correct because an interrupted select does not report anything.
And then the loop will be restarted to call select again.

Yes, that's what I thought should be happening. Sorry if that was
unclear.
So the question is still why no input is being reported, although
wait_reading_process_output should loop and call `select' again.

You were clear. I was the one who muddied the waters by misreading the
code, and Andreas correctly pointed out that I was wrong.

Yes, that's the question. I'll have to go back to my debugging.

OK, I figured out what's happening, and it is related to SIGALRM after
all. In line 4406 of process.c, wait_reading_process_output reduces the
timeout for the select call (under certain circumstances) in an attempt
to prevent select from being interrupted by SIGALRM. This seems to me
to be inherently unreliable, and, in particular, it consistently fails
on Cygwin. In other words, the SIGALRM is delivered before select times
out, causing select to get interrupted. So wait_reading_process_output
does indeed loop, and select fails every time (except when a key is
pressed).
If I block SIGALRM before the call to select (in the situation where the
timeout was reduced), the problem is solved. I need to do some more
testing, but so far I don't see any sign that this causes other problems.
One tricky thing is that blocking SIGALRM has to be done right before
the call to the *system* select. In the build with GTK support, this
call is inside xg_select, and things break if SIGALRM is blocked before
the call to xg_select. So I'm not sure what's the best way to handle
this. I'll keep thinking about it, but suggestions are welcome.

Why does reducing the timeout works on, say, GNU/Linux, but not on
Cygwin? What is different? Clock granularity, perhaps?

Why is it a problem that `select' fails? It should not be a problem: in
the worst case it should only mean that Emacs does "busy waiting" and
uses up more CPU than needed. But it shouldn't prevent Emacs from
reading input from processes (which IIUC is the actual problem we're
trying to solve).

You're right. I wasn't thinking clearly. The problem is not solved.

Sorry, I'm wrong again. As Stefan pointed out, it's harmless that
select gets interrupted by SIGALRM. That can't explain the gdb problem,
which still isn't solved.

For the third (and final?) time, I think I've figured out the problem.
It has nothing to do with emacs or select, but is simply a problem with
Cygwin's gdb. When the current Cygwin gdb is given too many input lines
before having its output read, it sometimes stops producing output and
waits for the user to press Return.
This is what was happening during the initialization of M-x gdb, and
that explains why I could work around the problem by inserting
(sleep-for .1) before the initialization was finished.
I've found a way to reliably reproduce this, and I've reported it to the
Cygwin list.
I'm not closing this bug report yet because I want to wait and see how
the Cygwin problem is resolved. It may still be necessary to use some
kind of workaround.
Thanks to all who tried to help and who put up with my mistakes and
misunderstandings.

This has now been fixed in the Cygwin development trunk. The fix will
be in Cygwin 1.7.10, which will probably be released before Emacs 24.1,
so I'm closing the bug.
