[New-bugs-announce] [issue37754] alter size of segment using multiprocessing.shared_memory

[Vinay Sharma]

New submission from Vinay Sharma <vinay0410sharma at gmail.com>:

Hi,
I am opening this to discuss about some possible enhancements in the multiprocessing.shared_memory module.

I have recently started using multiprocessing.shared_memory and realised that currently the module provides no functionality to alter the size of the shared memory segment, plus the process has to know beforehand whether to create a segment or open an existing one, unlike shm_open in C, where segment can be automatically created if it doesn't exist.


For an end user perspective I believe that these functionalities would be really helpful, and I would be happy to contribute, if you believe that they are necessary.

I would also like to mention that I agree this might be by design, or because of some challenges, in which case it would be very helpful if I can know them.
