> Issue #8407: The signal handler writes the signal number as a single byte
Wakeup test using two pending signals fails on FreeBSD 6.4 buildbot:
======================================================================
FAIL: test_signum (test.test_signal.WakeupSignalTests)
----------------------------------------------------------------------
Traceback (most recent call last):
 File "/usr/home/db3l/buildarea/3.x.bolen-freebsd/build/Lib/test/test_signal.py", line 266, in test_signum
 self.check_signum(signal.SIGUSR1, signal.SIGALRM)

AssertionError: Sequences differ: (14,) != (30, 14)
Wakeup file only contains SIGALRM, not (SIGUSR1, SIGALRM), whereas SIGUSR1 is raised before SIGALRM.
Code of the test:
 
 def check_signum(self, *signals): 
 data = os.read(self.read, len(signals)+1) 
 raised = struct.unpack('%uB' % len(data), data) 
 self.assertSequenceEqual(raised, signals)
 def test_signum(self): 
 old_handler = signal.signal(signal.SIGUSR1, lambda x,y:None) 
 self.addCleanup(signal.signal, signal.SIGUSR1, old_handler) 
 os.kill(os.getpid(), signal.SIGUSR1) 
 os.kill(os.getpid(), signal.SIGALRM) 
 self.check_signum(signal.SIGUSR1, signal.SIGALRM)
