cysignals: interrupt and signal handling for Cython
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:
pass
The cysignals
package provides mechanisms to handle interrupts (and other signals and errors) in Cython code.
- Python >= 3.9
- Cython >= 0.28
- Sphinx >= 1.6 (for building the documentation)
1.12.0 (release candidate)
- Remove optional compile-time dependency on PARI/GP. [#166]

- Add support for Cython 3. [#174, #176, #182, #187]
- Add support for Python 3.12.
- Replace fprintf by calls to write, which is async-signal-safe according to POSIX. [#162]
- Introduce a general hook to interface with custom signal handling. [#181]
- Drop assembly code added after 1.10.3 that is not portable.
- Drop Python 2 support; bump minimum Python version to 3.6. [#142]

- Improved testing. [#139, #152, #154]
- Improved installation of cysignals with
pip install -e
. [#130]
- Fixed compilation of OpenMP modules that also use cysignals. [#128]
- Fixed segmentation fault that could occur when
sig_occurred()
is called recursively during garbage collection. [#127]

sig_on()
as opposed to outside them.

package. [#113]
