Shouldn't we simply remove the .cvsignore files? Subversion doesn't use them, so they'll just end up getting out of sync with the svn:ignore properties. -Fred -- Fred L.

Conversion to Subversion is complete
by martin＠v.loewis.de Oct. 29, 2005

Oct. 29, 2005

The Python source code repository is now converted to subversion; please feel free to start checking out new sandboxes. For a few days, this installation probably still needs to be considered in testing. If there are no serious problems found by next Monday, I would consider conversion of the data complete. The CVS repository will be kept available read-only for a while longer, so you can easily forward any patches you may have. Most of you are probably interested in checking out one of these folders: svn+ssh://pythondev@svn.python.org/python/trunk svn+ssh://pythondev@svn.python.org/python/branches/release24-maint svn+ssh://pythondev@svn.python.org/peps The anonymous read-only equivalents of these are http://svn.python.org/projects/python/trunk http://svn.python.org/projects/python/branches/release24-maint http://svn.python.org/projects/peps As mentioned before, in addition to "plain" http/WebDAV, viewcvs is available at http://svn.python.org/view/ There are some more things left to be done, such as updating the developer documentation. I'll start working on that soon, but contributions are welcome. Regards, Martin

PEP 343 updated with outcome of recent discussions
by Nick Coghlan Oct. 29, 2005

Oct. 29, 2005

Once the cron job works it magic, the updated PEP 343 should be available on the website. As far as I am aware, there aren't any more open issues, so it is once again ready for BDFL pronouncement. I also tinkered with the example naming a bit, and added a new example for the "nested" context manager (it turns out there *were* mistakes in the last version I posted here - I had the deque method name wrong, and I wasn't invoking __context__ correctly on the nested contexts). Cheers, Nick. P.S. My availability will be sketchy for the rest of this weekend, then nonexistent until next weekend, so don't be surprised if I don't respond to messages before then. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia --------------------------------------------------------------- http://boredomandlaziness.blogspot.com

PEP 352: Required Superclass for Exceptions
by Brett Cannon Oct. 29, 2005

Oct. 29, 2005

Well, I am at it again, but this time Guido is a co-conspirator. We wrote a PEP that introduces BaseException and moves KeyboardInterrupt and SystemExit. Even if you followed the discussion for PEP 348 you should read the PEP since I am sure there will be something that someone doesn't like, such as the transition plan or how I didn't use British English throughout. =) Anyway, as soon as the cron job posts the PEP to the web site (already checked into the new svn repository) have a read and start expounding about how wonderful it is and that there is no qualms with it whatsoever. =) -Brett

Help with inotify
by Neal Becker Oct. 28, 2005

Oct. 28, 2005

I'm trying to make a module to support inotify (linux). I put together a module using boost::python. Problem is, inotify uses a file descriptor. If I call python os.fdopen on it, I get an error: Python 2.4.1 (#1, May 16 2005, 15:15:14) [GCC 4.0.0 20050512 (Red Hat 4.0.0-5)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from inotify import * >>> import os >>> i=inotify() >>> i.fileno() 4 >>> os.fdopen (i.fileno()) Traceback (most recent call last): File "<stdin>", line 1, in ? IOError: [Errno 21] Is a directory Any ideas? I'd rather not have to trace through python if I could avoid it (I don't even have source installed here).

MinGW and libpython24.a
by David Abrahams Oct. 27, 2005

Oct. 27, 2005

Is the instruction at http://www.python.org/dev/doc/devel/inst/tweak-flags.html#SECTION0006220000… still relevant? I am not 100% certain I didn't make one myself, but it looks to me as though my Windows Python 2.4.1 distro came with a libpython24.a. I am asking here because it seems only the person who prepares the installer would know. If this is true, in which version was it introduced? Thanks, -- Dave Abrahams Boost Consulting www.boost-consulting.com

Re: [Python-Dev] Proposed resolutions for open PEP 343 issues
by Michael Chermside Oct. 27, 2005

Oct. 27, 2005

Guido writes: > I find "AttributeError: __exit__" just as informative. Eric Nieuwland responds: > I see. Then why don't we unify *Error into Error? > Just read the message and know what it means. > And we could then drop the burden of exception classes and only use the > message. > A sense of deja-vu comes over me somehow ;-) The answer (and there _IS_ an answer) is that using different exception types allows the user some flexibility in CATCHING the exceptions. The discussion you have been following obscures that point somewhat because there's little meaningful difference between TypeError and AttributeError (at least in well-written code that doesn't have unnecessary typechecks in it). If there were a significant difference between TypeError and AttributeError then Nick and Guido would have immediately chosen the appropriate error type based on functionality rather than style, and there wouldn't have been any need for discussion. Oh yeah, and you can also put extra info into an exception object besides just the error message. (We don't do that as often as we should... it's a powerful technique.) -- Michael Chermside
