Interrupt and signal handling for Cython

Project description

Cython and interrupts

When writing Cython code, special care must be taken to ensure that the code can be interrupted with CTRL-C. Since Cython optimizes for speed, Cython normally does not check for interrupts. For example, code like the following cannot be interrupted in Cython:

while True:

The cysignals package provides mechanisms to handle interrupts (and other signals and errors) in Cython code.


  • Python 2.7 or Python >= 3.4
  • Cython >= 0.28
  • Sphinx >= 1.6 (for building the documentation)
  • PARI/GP (optional; for interfacing with the PARI/GP signal handler)
