>This looks interesting. The 32-bit limitation is a bit of a bummer, but I suppose that can be lifted, right ? Right. Already lifted. I wasn't actually realizing that installing additional python version could cause people so much trouble.
>Here's an old project trying to do more or less the same: >http://poshmodule.sourceforge.net/ Yes, in my previous article on habr I specifically mention it. I actually borrowed lots of of techniques from it (memory handles, shared heap, object copy/proxy), I even called my project similarly. However, I went far beyond the POSH implementation by solving the key problem - how to use those objects correctly. POSH provides some very basic optional locking. Countrary, I implemented real atomic transactions to manipulate shared objects with unprecedented safety and simplicity. Despite the similarities, you can see my own code is 4 time as large as POSH, so there much more differences than similarities, that's why I called it differently. >Another newer one, which is specific to numpy arrays: >https://pypi.org/project/SharedArray/ That is the strangest and probably useless thing I met so far. It provides absolutely no synchronization and writes the data to a file for some reason (to just list the shared objects he could keep the files empty). It seems like the author had no idea what he was doing. >For more general purpose types, there's Apache Arrow's >Plasma store: >https://arrow.apache.org/docs/python/plasma.html Yes, that's the most popular thing for a general purpose sharing of memory. However, it's not python-friendly and implies no mutation on shared memory. Although it's good for communicating between python and external programs. _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/HCXHJ5YXCN5XHHJUCCTKSK6YOKB5ZVSO/ Code of Conduct: http://python.org/psf/codeofconduct/
