PEP 487 vs 422 (dynamic class decoration)
by PJ Eby April 2, 2015

April 2, 2015

I recently got an inquiry from some of my users about porting some of my libraries to Python 3 that make use of the Python 2 __metaclass__ facility. While checking up on the status of PEP 422 today, I found out about its recently proposed replacement, PEP 487. While PEP 487 is a generally fine PEP, it actually *rules out* the specific use case that I wanted PEP 422 for in the first place: dynamic addition of callbacks or decorators for use at class creation time without requiring explicit … [View More]

OpenBSD buildbot has many failures
by Victor Stinner April 2, 2015

April 2, 2015

Hi, The OpenBSD buildbot always fail with the same failures since many months (ex: test_socket). Is someone interested to fix them? If no, would it be possible to turn it off to get a better view of regressions? Currently, they are too many red buildbots to quickly see regressions introduced by recent commits. http://buildbot.python.org/all/builders/x86%20OpenBSD%205.5%203.x Victor

AF_IUCV support for sockets
by Neale Ferguson April 1, 2015

April 1, 2015

Hi, I have opened an enhancement request (23830) with a suggested path that adds support for the AF_IUCV protocol family: IUCV is a hypervisor mediated communications method for z/VM guest virtual machines. Linux on z Systems (aka s390x) has supported this via the use of AF_IUCV sockets for many years (added to kernel Feb 2007). This suggested patch adds support to Python 2.7.9 for this socket type. I have built Python on both s390x and x86_64: both build cleanly and the test added to … [View More]

http.client: Determining Content-Length
by Demian Brecht April 1, 2015

April 1, 2015

Hi all, I'm not sure whether this should be python-list or here, but given it's a premature code review for http.client, I figured I'd post here first. I'm in the process of adding support for chunked transfer encoding to http.client (issue #12319). One of the bits of functionality that I'm working on in is ironing out some of the kinks out in determining the content length of the request bodies. Given the number of data types allowed as bodies it does get a little messy, so I wanted to get … [View More]

MemoryError and other bugs on AMD64 OpenIndiana 3.x
by Victor Stinner April 1, 2015

April 1, 2015

Hi, The buildbot AMD64 OpenIndiana 3.x is always red since at least 6 months. Almost always, tests fail because the buildbot has not enough memory. Well, it's fun to see how Python handles MemoryError (it's pretty good, there is no hard crash! my work on failmalloc was maybe useful ;-)), but it doesn't help to detect regressions. Would it be possible to enhance this buildbot? I copy this email to the owner of buildbot. But I also sent it to python-dev because MemoryError is not the only … [View More]
