Hi, can I make sure that Python uses only async-signal safe glibc functions in signal handlers? For example, you must not call malloc or free in signal handlers, see http://www.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_04.html#tag_02_04_03 The reason is, that if a signal is caught while your program is in the malloc routine, and the signal handler calls malloc or free again, then the heap will be corrupted, probably crashing your program. Using the Python module "signal", I can define signal handlers, but I guess that many statements like assignments to local variables will involve calls to functions like malloc or free. So, is there a) any mechanism inside Python that can detect if the current code is executed in a signal handler, or b) a list of statements that must not be used in a Python signal handler in order to avoid glibc function calls that are not async-signal safe?
