The frozendict builtin type was rejected, but we are going to add types.MappingProxyType: see issue #14386. types.MappingProxyType(mydict.copy()) is very close to the frozendict builtin type. Victor Thanks, Victor. :) Will this mean the new dict subclass for CPython will not expose dictprox

Hi, Does anyone object if I submit my patches sxs.patch and errnomodule.patch? These allow python to work correctly when built with vs2010. There is also the PCBuild10.patch, but that can wait. I'm sure a number of people are regularly building python using vs2010 using their own modified s

Does anyone object if I submit my patches sxs.patch and errnomodule.patch? These allow python to work correctly when built with vs2010. Please see my review: "allow to work correctly" is not a good explanation of what it does, and why it does that. As it is highly counter-intuitive, it needs at
Re: [Python-Dev] Using Cython for developing a module to be used from postgreSQL/pl/python
Can you recommend a similar place for asking the same queston about ctypes ? That is using ctypes for calling back to "outer" c application which embeds the python interpreter. ISTM that Postgres lists should be the best place for this kind of question. Alternatively, try python-list or db-sig.
