building a module catalogue with buildbot
by Fredrik Lundh Jan. 26, 2006

Jan. 26, 2006

I've been playing with "automatic module discovery" in an attempt to figure out how complete the library reference really is. I've created a simple script that tweaks the path to get rid of site-package stuff, and then scans the path for python modules and extensions, and writes the result to a text file. By combining module lists from different sources, you can trivially generate all sorts of custom module indexes (e.g. modules available on typical linux machines, modules not available in 2.5 on windows, etc). For some examples etc, see: http://effbot.org/lib/index-24.html http://effbot.org/lib/index-23.html http://effbot.org/lib/index-win32.html http://online.effbot.org/2006_01_01_archive.htm#20060110 http://online.effbot.org/2006_01_01_archive.htm#module-count Most importantly, this makes it easy to track down missing reference pages, and generate stubs for pages that "should exist". My initial thought was that we could ask alpha testers to run this script on their alpha builds, and report back, but it just struck me that the "buildbot" already builds stuff on a couple of interesting platforms. Can buildbot deal with custom test/validation scripts, and collect the output somewhere ? </F>

Include ctypes into core Python?
by Thomas Heller Jan. 26, 2006

Jan. 26, 2006

I would like to suggest to include ctypes into core Python, starting with the 2.5 release. ctypes is nearing the 1.0 release, and works on Windows, OS X, linux, possibly other platforms (provided that the processor is supported by libffi), and just recently even on Windows CE. ctypes does not depend on a libfii library installed on the system, instead the libfii source code is compiled into the extension module. libffi is copyright Red Hat, Inc, and released under a MIT style license. Up-to date docs for ctypes still have to be written, but I assume that the 2.5 release timeframe leaves enough time for that. Thomas

Thank you. > This fix doesn't completely eliminate the race, but should make it > near impossible to trigger. Hopefully it's good enough. Which race do you have in mind? The server socket doesn't need to do .accept() before a client socket can connect -- the server socket only needs to have done .listen() for a connection to succeed. > + listener_ready = threading.Event() ... [in the server] > s = socket.socket() > s.bind(('', PORT)) > s.listen(5) > + listener_ready.set() > s.accept() ... [in the client] > def connector(): > + listener_ready.wait() > s = socket.socket() > s.connect(('localhost', PORT)) Because the server doesn't set listener_ready until after the server has done listen(), and the client waits for that event, it "should be" 100% reliable that the client's connect() succeeds. Or do you have some other race in mind?

Know anyone interested in a Google internship?
by Guido van Rossum Jan. 25, 2006

Jan. 25, 2006

Sorry for the plug. Google is looking to fill an unprecedented number of student intern positions this summer, at several US locations (Mountain View, Santa Monica, Kirkland (Wash.), and New York). If you're interested or know someone interested, please see http://www.google.com/jobs/intern.html. Candidates from outside the US are welcome. The perks are incredible (just ask Brett Cannon, who's coming back for the second year this summer :-). We're not just looking for software development interns -- there are also product management positions, and UI design and usability analyst positions. I can't guarantee that I'll be mentoring you, but if you end up using Python in Mountain View, I'm sure we'll be interacting quite a bit! -- --Guido van Rossum (home page: http://www.python.org/~guido/)

New Pythondoc by effbot
by Georg Brandl Jan. 25, 2006

Jan. 25, 2006

What Fredrik hacks together there (http://www.effbot.org/lib) is very impressive. I especially like the "permalinks" in this style: http://effbot.org/lib/os.path.join What I would suggest (for any new doc system) is a "split" view: on the left, the normal text, on the right, an area with only the headings, functions, example and "see also" links (which preferably stays in sight). This way, you always keep the outline in view. Of course, I wouldn't say no to a user-commenting system, but this would have to be moderated. What I'm also curious about regarding the current docs, why are optional arguments in function declarations not written in Python style? regards, Georg PS: Fredrik, if I can help you, please tell me!

pystate.c changes for Python 2.4.2
by Gabriel Becedillas Jan. 24, 2006

Jan. 24, 2006

Hi, At the company I work for, we've embedded Python in C++ application we develop. Since our upgrade to Python 2.4.2 from 2.4.1 we started hitting Py_FatalError("Invalid thread state for this thread") when using debug builds. We use both multiple interpreters and thread states. I think the problem is that PyThreadState_Delete (which is used when I destroy thread states and interpreters) is not making the same clean up that PyThreadState_DeleteCurrent is doing (which is used when we create threads from python code). If a thread id is reused (obviously not between two running threads), and the previous thread used PyThreadState_Delete instead of PyThreadState_DeleteCurrent, then an old and invalid value for autoTLSkey is still stored, and that is triggering the Py_FatalError when a call to PyThreadState_Swap is made. If I add this code at the end of PyThreadState_Delete: if (autoTLSkey && PyThread_get_key_value(autoTLSkey) == tstate) PyThread_delete_key_value(autoTLSkey); then everything works fine. Could you please confirm if this is a bug ? Thanks a lot and have a nice day.

Code that depends on the current situation, _TestCase__attributename. Fragile code, to be sure, but still. If there were a compelling reason to backport, I guess it could be hacked to work right-ish, but subclassing TestCase in this way, while convenient, isn't important enough to warrant this (IMHO). -- Thomas Wouters <thomas(a)xs4all.net> Hi!
