Hey All!

Please let me know I am included within the accepted organization or not?

According to Karachi, Pakistan timezone last night was my GSoC'23 result.

Please guide me through the procedure how to check my GSoC'23 result.

Name :- Sumaiya Qureshi (Karachi, Pakistan)

I opted for Improvements to mathematics interaction with the desired
organization "Oppia" within Web category.

Let me know if you all sage developers want further information regarding
myself to search my result.

Regards,
Sumaiya.

sig_on/sig_off can be used in library interfaces where the performance
impact may be noticeable.  I'd like to see a direct comparison before
putting in much effort to switch to something else.

[sage-devel] cysignals/sig_on...sig_off

2023-04-30 Thread 'jonatha...@googlemail.com' via sage-devel 
Hi,

it's been over a year since the last activity on 
https://github.com/sagemath/cysignals.

This could well be, because it is a good shape, but looking at the issues, 
I'm not too sure about that. Here are some issues, I know of:

- sig_on/sig_off is poorly maintained and not thread safe
- cysignals is not pip installable and highly platform dependent (and on a 
platform even depends very much on the compiler).
- Memory: Interrupting sig_on...sig_off will not clean up the heap.

I would argue:

-  To my knowledge, `sig_check` is pretty much equivalent to `
PyErr_CheckSignals` (https://github.com/sagemath/cysignals/issues/145)
- Instead of using `sig_on...sig_off` for our own functions, we should 
check for signals at reasonable places.
- External calls should be interrupted with standard tools and not our own 
custom tool.

While the action on the first item is quite obvious (I didn't even check if 
anything needs to be done here), I have not done my research on the second 
point and what the alternatives are.

Before I dig into possible options of replacing `sig_on...sig_off`, I would 
like to gather your opinions:

Does cysignals get enough support to keep going or do we want to try a 
different approach? This different approach will for sure not be as 
efficient, but will probably need less effort to maintain.
