inject memory allocation faults

Project description

Debug tool for Python injecting memory allocation faults to simulate a low memory system to test how your application handles MemoryError exceptions.

pyfailmalloc is based on the PEP 445Add new APIs to customize Python memory allocators” and so requires at least Python 3.4.


  • failmalloc.enable(range: int=1000): schedule a memory allocation failure in random.randint(1, range) allocations.
  • failmalloc.disable(): cancel the scheduled memory allocation failure

The version can be read from failmalloc.__version__ as a string (ex: "0.1").


Version 0.2 (2015-01-27)

  • Support Python 3.5: hook also calloc(), support the new PyMemAllocatorEx API
  • Add tox.ini to run tests using tox

Version 0.1 (2013-07-08)

  • First public version
