Since this is in typeobject.c, my point was that it probably should be made "semi-colon safe" even though it's not generic yet. Tim Delaney

the new profiler and profiling c calls
by Simon Percivall July 12, 2004

July 12, 2004

I think there's a slight problem with the profiling of C calls in the new profiler. When profiling method calls, the C function name is the repr() of the method, which means that a call for instance on str.endswith on different string instances ends up as completely separate calls. This might be intentional, but it's different than the way Python code is profiled, and it's irritating. Testing if a thousand different lines ends in a certain way means the default output from profile gets … [View More]

urllib.urlretrieve() and handling 550 errors when reading from FTP
by Brett C. July 12, 2004

July 12, 2004

Bug #635453 reports that when you use urllib.urlretrieve() to read from an FTP server and the file you are trying to get does not have the proper permissions for you, you are given a listing of the directory instead of an exception (this is all done by Lib/urllib.py:752). Now this doesn't make sense to me and I suspect most people would agree. But having that explicit line there on top of it having been in the file since it was renamed from urlopen way backin 1994 makes me hesitate … [View More]

[Raymond Hettinger] #- This should be tackled in steps and as part of larger #- improvement to the #- context API. Previous to 2.4 final? I'm very sorry about helping you, but I'm very complicated with my times, and not sure about my free time from here to several weeks (an example is the last bugday, I was willing to help, and even downloaded the CVS files (+3 hours on a 28.8 modem), but the Saturday worked from 8am to 10pm). Anyway, I trust your decisions. #- As a first step, I would … [View More]

Comparison and (user) confusion
by François Pinard July 12, 2004

July 12, 2004

Hi, people. Yesterday, as a user, I made a little bug which I quickly resolved, but over which I could have spent some time, having been younger to Python. The problem appeared when I sub-classed `list', and used a `__cmp__' method in my sub-type to effect a specialised sort. The sort did not behave as expected, as the `list' type provides rich comparisons, and that `sort', finding `__lt__', merely ignored my own `__cmp__'. I wonder if Python could not have helped better here, by diagnosing … [View More]

Bug day outcome
by A.M. Kuchling July 12, 2004

July 12, 2004

The bug day ended up closing 15 bugs and 18 patches. Thanks to everyone who participated. A few python-dev people were around for much of the day; in particular Brett Cannon was really helpful in processing bugs and keeping the Wiki page updated. Anthony has said he expects an alpha2 in three weeks or so. That puts the next release around July 29th. I suggest Saturday, August 7th as the next bug day. (Or would Sunday be better for people?) --amk
