A very large timeout was getting converted to a 0 wait and causing
some unit tests to fail in strange and random ways. Not trapping
large timeouts was an oversight when converting to waitable timers
on WIN32
If a test program reports test failures, the Perl wrapper
must return the same error status. On Windows where we use
system() instead of exec() that needs some value fiddling.
Creates a file .taps-failed in each O.<arch> directory,
appending the name of each tapfile that has failures to it.
The testFailures script now reads the .taps-failed files
from each directory listed in .tests-failed and nicely
displays the failing tests listed in each.
Records with lower PHAS value than any previously loaded records
were inserted at the end of the list rather than at the beginning.
This fixes lp: #1899697. Also fixes a proto-bug in that the second
argument to the previously used ellAdd() call assumed that
offsetof(scan_element, node)==0.
Thanks to Bruno Martins for providing this patch.
If fastReceiver() took more than 0.01 seconds to exit,
sleepySender() might have pushed a second message onto
the queue after setting recvExit, so there would be an
extra message in the queue for the next test, which I
was seeing on Appveyor. That's my current theory...
The internal mySend() and myReceive() routines do expect a timeout
of -1 to mean wait forever, see the epicsMessageQueueSend() and
epicsMessageQueueReceive() API routines.
Move the code that wakes up the next sending task to after we've
added our threadNode to the receiveQueue. He still has to wait for
us to release the Mutex though, so this might make no difference.
This commit also changes when we decrement the number of waiting
senders so it always happens immediately after a threadNode gets
taken off the sendQueue by the code that removed it.
When sending a message, if the queue is full so we have to wait, we
create a threadNode with an eventNode in it and stick it on the
sendQueue, then wait for a receiver to signal that event, waking us.
If we awoke due to a timeout but a receiver was actually waking us
up anyway (i.e. eventSent was set), we shouldn't give up.
Introduced freeEventNode() which ensures eventNodes don't have a
signalled event in them before returning the node to the freeList.
Callers pass the status from epicsEventWaitWithTimeout() to indicate
whether it was signalled or not. If it timed out we must trigger it
and Wait to clear the event state.
It appears that previously a negative timeout actually implemented a
'wait forever', but the VxWorks and RTEMS implementations both check
for (timeout <= 0) and return immediately if nothing can be done
without waiting.
