[Cython] candidate for bug fix release 0.22.1
Hi everyone, here is a release candidate for the upcoming bug fix release 0.22.1. http://cython.org/release/Cython-0.22.1rc1.tar.gz http://cython.org/release/Cython-0.22.1rc1.zip cdf6726d3717351b7d4845f7b3853c3f Cython-0.22.1rc1.tar.gz e480ddd0f45289e22ea624f530116719 Cython-0.22.1rc1.zip Here's the changelog: https://github.com/cython/cython/blob/0.22.x/CHANGES.rst Please give it some testing and report success or failure, especially on less tested platforms like MS-Windows. Being a bug-fix release, it shouldn't break anything but improve the stability and compatibility of the current release series. As soon as this release is out (hopefully within a couple of days), we'll start preparing the next major feature release 0.23. Here's a teaser: https://github.com/cython/cython/blob/master/CHANGES.rst Stefan ___ cython-devel mailing list cython-devel@python.org https://mail.python.org/mailman/listinfo/cython-devel
[Cython] cython-0.23 monkey-patches stdlib?
According to https://github.com/cython/cython/blob/master/CHANGES.rst the default build would attempt to modify python stdlib files? How would this work on distributions? I am maintainer for Cython on Fedora. So installing Cython would try to overwrite stdlib files? That sounds difficult. For one thing, it means more than 1 package would own the same files. And I don't know if the general user community would like this approach. ___ cython-devel mailing list cython-devel@python.org https://mail.python.org/mailman/listinfo/cython-devel

No. Glad you asked, that might not be clear. It will not modify the *files*, only the content of the modules after importing them. It adds the missing ABCs to the collections.abc module and registers Cython's own types with them *at runtime*. Here's what it does: https://github.com/cython/cython/blob/bb0dec2/Cython/Utility/Coroutine.c#L1322 This is a bit fragile, like all monkey-patching. As long as things get imported in the right order, it works. But if you import asyncio before a Cython module that adds the ABCs, it may already have decided that the ABCs don't exist and won't use them. That's controllable on user application side, though. Also, the first patcher necessarily wins, so if there will ever be updates to the ABCs, old Cython modules would still patch in the old versions when imported first. They should tend to be quite stable, though. In any case, this will get better over time as more code switches to Py3.5 and later.
