Need closure on __cmp__ removal
by Guido van Rossum Jan. 5, 2008

Jan. 5, 2008

In the past some folks have been pushing for the resurrection of (some form of) __cmp__, which is currently removed from Py3k (except for some remnants which we'll clean up in due time). I'd like to get closure on this issue. If someone volunteers within a week to write a PEP, I'll give them a month to write the PEP, and then I'll review it. The PEP better come with a patch implementing (roughly) the desired behavior as well, relative to the 3.0 branch. If I don't hear from a committed … [View More]

Bug day tasks
by A.M. Kuchling Jan. 5, 2008

Jan. 5, 2008

I've updated the bug day pages in the wiki: http://wiki.python.org/moin/PythonBugDay http://wiki.python.org/moin/PythonBugDayStatus How do we want to flag good candidate bugs? Should we add a keyword to Roundup, or just list them on the PythonBugDayStatus wiki page? Another task is to get logging set up for the #python-dev IRC channel. Searching didn't find any existing archive; we could run it on python.org somewhere, but does anyone here already run an IRC logging bot? Maybe someone … [View More]

long(float('nan')) conversion
by Christian Heimes Jan. 5, 2008

Jan. 5, 2008

Hello! Bug http://bugs.python.org/issue1481296 describes a problem where long(float('nan')) causes a seg fault on Mac OS X. On other platforms it returns 0L, e.g. Python 2.5.1 (r251:54863, Oct 5 2007, 13:36:32) [GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> float('nan') nan >>> long(float('nan')) 0L My patch to Python 2.6 adds an explicit check for NaNs to always return 0L. It … [View More]

Backport threading.py fix to 2.5.2?
by Guido van Rossum Jan. 5, 2008

Jan. 5, 2008

See http://bugs.python.org/issue1731. Should we consider it safe to backport r57216 to 2.5.2? This is Thomas Wouters's code to disable spurious tracebacks when daemon threads die. We're running some 2.4 apps with (a variant of) this at Google that get many 1000s of invocations a day, so I'm pretty confident that it works. -- --Guido van Rossum (home page: http://www.python.org/~guido/)

Check for signals during regular expression matches (issue846388)
by Ralf Schmitt Jan. 4, 2008

Jan. 4, 2008

Hi all, Currently the re module does not handle signals. I've been once a victim of such a case in a real world setup (i.e. the python interpreter seems to hang at 100% CPU and is not interuptible with control c) http://bugs.python.org/issue846388 opened 4 years ago contained a patch for this issue (which ofcourse didn't apply). I've updated that patch and added an example regular expression, which 'hangs' the python interpreter. I think this issue should be handled. Regards, - Ralf

Hi all, I've added a patch implementing a wrapper for siginterrupt on linux/unix like platforms and attached it to http://bugs.python.org/issue1089358 (which mentions a need for siginterrupt). Any chance to get this in? Regards, - Ralf

Bug day proposal: January 19th
by A.M. Kuchling Jan. 4, 2008

Jan. 4, 2008

A while ago Georg suggested holding a bug day some time soon. I suggest Saturday January 19th. It's a weekend day; it gives us two weeks to prepare by drawing up bug lists; there's a PyPy sprint January 12-19 (http://codespeak.net/pypy/dist/pypy/doc/news.html), so it may be helpful to have the PyPy participants and the python-dev participants available via IM/IRC all at one time. January 12th or 13th would be an alternative date: less time to prepare, but still overlapping with PyPy (they'll … [View More]

Re: [Python-Dev] Syntax suggestion for imports
by Raymond Hettinger Jan. 4, 2008

Jan. 4, 2008

[GvR] > I wonder if your perceived need for this isn't skewed by your > working within the core? The need was perceived by a colleague who does not work on the core. My own skew was in the opposite direction -- I've seen the pattern so often that I'm oblivious to it. Before posting, I ran some scans of our code base at work and found plenty of examples (mostly third-party cmodules vs python equivalents and a few that searched for similar functionality in different packages). It might … [View More]

Syntax suggestion for imports
by Raymond Hettinger Jan. 4, 2008

Jan. 4, 2008

The standard library, my personal code, third-party packages, and my employer's code base are filled with examples of the following pattern: try: import threading except ImportError: import dummy_threading as threading try: import xml.etree.cElementTree as ET except ImportError: try: import cElementTree as ET except ImportError: import elementtree.ElementTree as ET try: from cStringIO import StringIO except ImportError: from StringIO import StringIO … [View More]
