thoughts on the bytes/string discussion
by Bill Janssen July 7, 2010

July 7, 2010

Here are a couple of ideas I'm taking away from the bytes/string discussion. First, it would probably be a good idea to have a String ABC. Secondly, maybe the string situation in 2.x wasn't as broken as we thought it was. In particular, those who deal with lots of encoded strings seemed to find it handy, and miss it in 3.x. Perhaps strings are more like numbers than we think. We have separate types for int, float, Decimal, etc. But they're all numbers, and they all cross-operate. In 2.x, … [View More]

Signs of neglect?
by Steve Holden July 6, 2010

July 6, 2010

I was pretty stunned when I tried this. Remember that the Tools subdirectory is distributed with Windows, so this means we got through almost two releases without anyone realizing that 2to3 does not appear to have touched this code. Yes, I have: http://bugs.python.org/issue9083 When's 3.2 due out? regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 See Python Video! http://python.mirocommunity.org/ Holden Web LLC http://www.holdenweb.com/ … [View More]

Taking over the Mercurial Migration
by "Martin v. Löwis" July 1, 2010

July 1, 2010

It seems that both Dirkjan and Brett are very caught up with real life for the coming months. So I suggest that some other committer who favors the Mercurial transition steps forward and takes over this project. If nobody volunteers, I propose that we release 3.2 from Subversion, and reconsider Mercurial migration next year. Regards, Martin

OS X buildbots: why am I skipping these tests?
by Bill Janssen July 1, 2010

July 1, 2010

My Leopard and Tiger PPC buildbots are momentarily green! But I'm looking into why I'm skipping some tests. My buildbots are up-to-date OS-wise and very vanilla, with the latest applicable Xcode. 4 skips unexpected on darwin: test_gdb test_ioctl test_readline test_ttk_guionly Three of these (gdb, readline, ttk_guionly) are just bad predictions of which tests should skip on Darwin, I think -- gdb is only version 6, so that test won't run, readline doesn't get built, ttk doesn't work … [View More]

Mailbox module - timings and functionality changes
by Steve Holden June 30, 2010

June 30, 2010

I hope this is an appropriate dev topic. It seems to me that the unicode discussions of recent days are well highlighted by difficulties I am having using the mailbox module (hardly surprising given the difficulties of handling email generally) even though it passes its tests. I can't find anything related in the issue tracker (symptoms: one program that works fine under Python 2 in under twenty seconds takes forever (over ten minutes) to fail while creating the (start, stop) index to the … [View More]

Pickle security and remote logging
by anatoly techtonik June 30, 2010

June 30, 2010

Hello, I need to send logging module output over the network. The module has everything to make this happen, except security. SocketHandler and DatagramHandler examples are using pickle module that is said to be insecure. SocketHandler and DatagramHandler docs should at least contain a warning about danger of exposing unpickling interfaces to insecure networks. pickle documentation mentions that it is possible to control what gets unpickled, but there is any no example or security analysis if … [View More]

what environment variable should contain compiler warning suppression flags?
by Brett Cannon June 30, 2010

June 30, 2010

I finally realized why clang has not been silencing its warnings about unused return values: I have -Wno-unused-value set in CFLAGS which comes before OPT (which defines -Wall) as set in PY_CFLAGS in Makefile.pre.in. I could obviously set OPT in my environment, but that would override the default OPT settings Python uses. I could put it in EXTRA_CFLAGS, but the README says that's for stuff that tweak binary compatibility. So basically what I am asking is what environment variable should I use?… [View More]

[ANN]: "newthreading" - an approach to simplified thread usage, and a path to getting rid of the GIL
by John Nagle June 28, 2010

June 28, 2010

We have just released a proof-of-concept implementation of a new approach to thread management - "newthreading". It is available for download at https://sourceforge.net/projects/newthreading/ The user's guide is at http://www.animats.com/papers/languages/newthreadingintro.html This is a pure Python implementation of synchronized objects, along with a set of restrictions which make programs race-condition free, even without a Global Interpreter Lock. The basic idea is that … [View More]
