Package: python-daemon Version: 2.0.5-1 Severity: important Tags: patch If you initialise DaemonContext with a signal_map as documented you get the following:
>>> import daemon, signal
>>> with daemon.DaemonContext(signal_map={signal.SIGTERM: 'terminate'}):
... pass
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/daemon/daemon.py", line 380, in
__enter__
self.open()

File "/usr/lib/python2.7/dist-packages/daemon/daemon.py", line 883, in
set_signal_handlers
signal.signal(signal_number, handler)
TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable
object
As a workaround, you can pass a unicode string (u'terminate').
The attached patch uses basestring instead of unicode for comparison
which ensures that the correct terminate handler is installed as
documented.

Description: fix handling of signal_map values This fixes the case where a non-unicode 'termniate' string is passed via the signal_map argument to the DaemonContext constructor.
