1.7.14-2: pthread_cancel and pthread_kill not working as expected

Greetings everyone,
while porting a project from Linux to Cygwin I noticed that pthread_cancel
was having trouble cancelling threads blocked on semaphores and reads
from stdin.
Another user had a similar problem a while ago:
http://sourceware.org/ml/cygwin/2011-01/msg00374.html
According to the follow-up this was fixed for network sockets, but
Windows seems to tread networks socket different from everything else
and the problem might not apply in my case.
The user also mentioned trying pthread_kill to "wake" blocked threads
so I tried that as well, but that resulted in completely different
threads in my program waking up.
My question is now whether I'm using pthread_cancel and pthread_kill
incorrectly or if there's some functionality missing in the certainly
not trivial Cygwin implementation of those functions.
A program to demonstrate the problems is attached. It contains six
different tests that behave slightly different depending on which
function the "simplethread" function blocks on.
You can find the expected and actual results that I got for the six
tests at the bottom of this mail. The expected results correspond to
what the readily available man-pages for pthread_cancel and pthread_kill
state and I verified the tests on a Linux system.
tl;dr version of the results:
- Using pthread_cancel on a blocked thread with deferred cancel blocks
the calling thread.
- Threads blocked on semaphores, reads from stdin or pause() aren't
cancelled.
- Signals seem to wake the wrong threads in some cases.
I have no explanation for this, so any ideas and suggestions are welcome.
Cheers,
Otto
Test 1:
Leave threads at deferred cancel and cancel each thread.
Expected result:
All threads are cancelled.
Actual result:
Blocking on semapthore: Main thread hangs on first call to pthread_cancel().
Blocking on pause(): Same as semaphore.
Blocking on read(): Not deterministic: Main thread hangs on random call
to pthread_cancel().
Test 2:
Set cancel type to asynchronous and cancel each thread.
Expected result:
All threads are cancelled.
Actual result:
Independent of what the threads are blocked on, nothing is cancelled.
Test 3:
Send SIGUSR1 once to each thread.
Expected result:
Each thread executes the signal handler once.
Actual result:
Blocking on semaphore:
Poking thread 2 (0x80020410)
Thread 0 encountered an error: Interrupted system call (0x80010298)
Poking thread 1 (0x80020370)
Thread 1 executes signal handler (0x80020370)
Thread 1 encountered an error: Interrupted system call (0x80020370)
Poking thread 0 (0x80010298)
Thread 2 executes signal handler (0x80020410)
Thread 2 encountered an error: Interrupted system call (0x80020410)
Woken threads don't correspond to signalled threads, not all of them
execute the signal handler.
Blocking on pause(): Same as semaphore.
Blocking on read(): One thread executes the signal handler, the other
two don't. Thread chosen seemingly at random. This could be a
side-effect of all threads reading from stdin, but I still seems
broken.
Test 4:
Send SIGUSR1 to one thread repeatedly (doesn't exit by design).
Expected result:
The target thread executes the signal handler each time.
Actual result:
Blocking on semaphore: Independent of the targeted thread, thread 0
wakes up once and executes the signal handler if thread 0 was
signalled. No thread cares about further signals.
Blocking on pause(): Same as semaphore.
Blocking on read(): Not deterministic: Targeted thread either executes
the signal handler every time or not at all.
Test 5:
Cancel each thread asynchronously and poke them with SIGUSR1 afterwards.
Expected result:
If a targeted thread isn't cancelled by pthread_cancel(), the signal
should wake it up so that the cancel event can be handled.
Actual result:
Blocking on semaphore:
Killing thread 2 (0x80020410)
Poking thread 2 (0x80020410)
Thread 0 encountered an error: Interrupted system call (0x80010298)
Killing thread 1 (0x80020370)
Poking thread 1 (0x80020370)
Thread 2 exiting (0x80020410)
Killing thread 0 (0x80010298)
Poking thread 0 (0x80010298)
Thread 1 exiting (0x80020370)
Responding threads don't correspond to signalled threads, wrong
threads exit if they have been cancelled already.
Blocking on pause(): Same as semaphore.
Blocking on read(): Not deterministic: One thread exits when poked,
the other two stay.
Test 6:
Cancel each thread asynchronously and poke them with SIGUSR1 until they
die.
Expected result:
If a targeted thread isn't cancelled by pthread_cancel(), the signal
should wake it up so that the cancel event can be handled. If the first
signal "misses", one of the following should hit.
Actual result:
Blocking on semaphore:
Killing and poking thread 2 will result in one response to the signal
from thread 0, then nothing.
Killing and poking thread 1 will result in one resposne to the signal
from thread 0, then nothing.
Killing and poking thread 0 will result in one response to the signal
from thread 1, then nothing.
Blocking on pause(): Same as semaphore.
Blocking on read(): Not deterministic: Either the first cancelled and
poked thread exits fine and the other two don't care or all three
don't care.
