Summary: bug in threading implementation using guile-1.6.1
Original Submission: hello,
I am using multiple threads within a guile-gtk application.
a call to (gtk-threads-ensure-handler) ensures that a first thread gets started, and
allows the rest of my program to execute. At the end of that program, I call (gtk-main), to
wait in the Gtk event thread.
If I run my program without starting a second thread, it is ok, but as soon as I invoke
(gtk-threads-ensure-handler), my CPU is used at 100%
NOTES:
1: I configured guile-1.6.1 using the "--with-threads" flag.
2: if I strace my process, I see this:
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
gettimeofday({1041338430, 454970}, NULL) = 0
gettimeofday({1041338430, 455055}, NULL) = 0
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
gettimeofday({1041338430, 455767}, NULL) = 0
gettimeofday({1041338430, 455852}, NULL) = 0
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
gettimeofday({1041338430, 456429}, NULL) = 0
gettimeofday({1041338430, 456511}, NULL) = 0
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
gettimeofday({1041338430, 457084}, NULL) = 0
gettimeofday({1041338430, 457166}, NULL) = 0
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
gettimeofday({1041338430, 459008}, NULL) = 0
gettimeofday({1041338430, 459097}, NULL) = 0
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
gettimeofday({1041338430, 459688}, NULL) = 0
gettimeofday({1041338430, 459771}, NULL) = 0
ioctl(7, FIONREAD, [0]) = 0
select(32, [6 7], [], [], {0, 0}) = 1 (in [6], left {0, 0})
and so on....
--> I suspect a bug in the implementation of
coop_wait_for_runnable_thread () in libguile/isselect.c
if (QFIRST (coop_global_sleepq)->timeoutp)
gettimeofday (&now, NULL);
return coop_wait_for_runnable_thread_now (&now);
...
thanks a lot,
Stan

Well, this is not a correct usage pattern. (gtk-ensure-handler)
spawns a gtk handler which handles all events of the application.
That is, it is an *alternative* to (gtk-main).
If your intention with calling gtk-main is to wait for the application
to quit, I suggest that you wait on a condition variable instead.
Then make sure that it is signalled when the application quits.
(But maybe someone else more versed in guile-gtk have a better
suggestion.)
If I do what you describe in an interactive guile session, I get a lot
of glib warning messages which are properly informative:
g_main_iterate(): main loop already active in another thread
It would of course be nicer not to get stuck in a loop but just get
*one* error message...
Best regards,
Mikael Djurfeldt
