Subversion forbidden error while committing to trunk
by Alexandre Vassalotti 08 Dec '07

08 Dec '07

Hi, I tried a few times to commit a patch (for issue #1530) to the trunk, but I always get this error: alex:python% svn commit Lib/doctest.py --file svn-commit.tmp svn: Commit failed (details follow): svn: MKACTIVITY of '/projects/!svn/act/53683b5b-99d8-497e-bc98-6d07f9401f50': 403 Forbidden (http://svn.python.org) I first thought that was related to the Py3k freeze. However, I tried again a few minutes ago and I still got this error. Is possible that my commit rights are limited to the py3k branches? Or this is a genuine error? Thanks, -- Alexandre

Split up the c-api documentation in smaller files?
by Christian Heimes 07 Dec '07

07 Dec '07

Good afternoon everybody! The new C API documentation contains some large files: 105K abstract.html 300K concrete.html 183K newtypes.html The concrete.html takes noticeable time to render on my computer (P4 2.4 with 1GB RAM, Firefox 2.0 and Ubuntu Linux). I estimate the load and rendering time is about 4-5 seconds! It also takes long to search for a string and scrolling isn't smooth, too. Can we split the files in smaller chunks, please? Christian

Py3k code freeze imminent; 3.0a2 release Friday
by Guido van Rossum 07 Dec '07

07 Dec '07

I'm planning to freeze the py3k branch in 2-3 hours, some time after/around 8pm PST (midnight UTC). If someone wants to do another svnmerge from the trunk please do it before then -- though we're nearly current so I don't mind not having the last few changes merged into this release (it's only Raymond's refactoring of __length_hint__ implementations). If there's anything you think really should be in this release, please speak up ASAP. Filing a high priority bug and assigning it to me would be a great way to get my attention. -- --Guido van Rossum (home page: http://www.python.org/~guido/)

PATCH: attribute lookup caching for 2.6
by Neil Toronto 07 Dec '07

07 Dec '07

So Jim and PJE finally convinced me to do it the right way. :) Thanks guys - it turned out very nice. http://bugs.python.org/issue1560 http://spreadsheets.google.com/ccc?key=pHIJrYc_pnIUpTm6QSG2gZg&hl=en_US It caches type/metatype attribute lookups, including missing attributes. Summary of the bug tracker issue: - Successful attribute lookups are 20% faster, even for classes with short MROs and (probably most) builtins - haven't tested unsuccessful lookups - Successful hasattr is 5-10% faster, unsuccessful is 5% faster (less impressive than above, and likely due to overhead - internally, all lookups are the same) - list.__init__ and list().__init__ are slower, and I can't figure out why (creating instances of subclasses of list will be a little slower, and this may show up in other builtin types) - I haven't benchmarked type attribute sets (how much do we care?) - it should be quite a bit faster than updating a slot, though - Caching missing attributes is crucial for good performance - The CreateNewInstances benchmark uncovered an issue that needs fixing; please see the tracker for details All kinds of commentary and feedback is most welcome.

tstate_delete_current infinite loop from PyThreadState_DeleteCurrent
by Gregory P. Smith 07 Dec '07

07 Dec '07

Has anyone else ever encountered a situation where a python process gets stuck in an infinite loop within Python/pystate.c tstate_delete_current() called from PyThreadState_DeleteCurrent() when a thread is exiting? (revealed by attaching to the looping process with a debugger) I'm seeing this (very rarely, reproducing it is difficult). In this case its python 2.4.3 but that code does not appear to have changed since then. -gps

Re: [Python-Dev] Does anyone care enough about asyncore and asynchat to help adapt their APIs for Py3k?

I guess that would be me, if you'll have me. I think asyncore and asynchat are valuable, and I'm willing to do what needs to be done to ensure that they remain in Py3k.
