what ports are needed for a buildbot?
by Bill Janssen 16 May '10

16 May '10

I'm running my buildbots in a captive firewalled subnet, and I have to enumerate all the ports that the buildbot is allowed to open to the outside world. Right now, I'm getting this error: ERROR: test_connect (test.test_smtpnet.SmtpSSLTest) ---------------------------------------------------------------------- Traceback (most recent call last): File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/test/test_smtpnet.py", line 15, in test_connect server = smtplib.SMTP_SSL(self.testServer, self.remotePort) File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/smtplib.py", line 757, in __init__ SMTP.__init__(self, host, port, local_hostname, timeout) File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/smtplib.py", line 239, in __init__ (code, msg) = self.connect(host, port) File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/smtplib.py", line 295, in connect self.sock = self._get_socket(host, port, self.timeout) File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/smtplib.py", line 762, in _get_socket new_socket = socket.create_connection((host, port), timeout) File "/Users/buildbot/buildarea/3.x.parc-leopard-1/build/Lib/socket.py", line 321, in create_connection raise error(msg) socket.error: [Errno 61] Connection refused This make me think that the list of ports enumerated at http://wiki.python.org/moin/BuildBot is incomplete. We need a complete list. If you know of additional ports, please add them to the wiki page. Bill

buildbot svn exceptions again...
by Bill Janssen 16 May '10

16 May '10

parc-leopard-1 (and most of the other builders) are failing the svn checkout with the following error: svn: PROPFIND of '/projects/python/trunk': Could not resolve hostname `svn.python.org': Temporary failure in name resolution (http://svn.python.org) When I log into that machine as "buildbot" and do the svn checkout manually using the following command /usr/bin/svn checkout --non-interactive --no-auth-cache --revision HEAD http://svn.python.org/projects/python/trunk build it works fine.

frozendict (was: Possible patch for functools partial...)
by Yaniv Aknin 16 May '10

16 May '10

> > > So I'm thinking either we make an > > immutable/hashable dict while we're at it, or store the keyword > > arguments as a tuple (which guarantees immutability), and only > > convert them back to a dict when you want to call the partial object > > (simpler, slower). > > I'd support an immutable dict. [...] I've set out to implement a frozendict (like frozenset) for use to store functools.keywords' attribute, and quickly realized I didn't think of an obvious flaw in that idea. A frozenset will only accept hashable members, but a frozendict can't afford this luxury for its values. I'm not sure how should I go about handling that, if at all. Should I implement a frozendict which will remain unhashable but support equality testing like a regular dict? A frozendict that is only hashable if all its values are hashable, like a tuple? Is the whole notion of a frozendict worthy, given this limitation? I'd be happy to hear python-dev's guidance on this. Cheers, - Yaniv

robots exclusion file on the buildbot pages?
by Antoine Pitrou 15 May '10

15 May '10

Hello, The buildbots are sometimes subject to a flood of "svn exception" errors. It has been conjectured that these errors are caused by Web crawlers pressing "force build" buttons without filling any of the fields (of course, the fact that we get such ugly errors in the buildbot results, rather than a clean error message when pressing the button, is a buildbot bug in itself). Couldn't we simply exclude all crawlers from the buildbot Web pages? Regards Antoine.

configuring the buildbot to skip some tests?
by Bill Janssen 14 May '10

14 May '10

I've got parc-tiger-1 up and running again. It's failing on test_tk, which makes sense, because it's running as a background twisted process, and thus can't access the window server. I should configure that out. I'm looking for documentation on how to configure the build slave so that it skips this test. Bill

HEADS UP: Compilation risk with new GCC 4.5.0
by Jesus Cea 14 May '10

14 May '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Zlib-devel] HEADS UP: Apparent bad compilation under (just released) GCC 4.5.0 <http://mail.madler.net/pipermail/zlib-devel_madler.net/2010-May/002267.html> GCC Bugzilla Bug 40838 gcc shouldn't assume that the stack is aligned http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40838 Short history: new GCC 4.5.0 (released a month ago), when compiling with - -O3, is adding MMX/SSE instructions that requires stack aligned to 16 byte. This is wrong, since x86 ABI only requires stack aligned to 4 bytes. If you compile EVERYTHING with GCC 4.5.0, you are safe (I guess!), but if your environment has mixed compiled code (for instance, the OS libraries), you can possibly "core dump". If you have an old compiled Python and you update libs compiled with GCC 4.5.0, you can crash in the process. Psyco is showing the issue, but it is not the culprit. It only leaves - -correctly- the stack in not 16-byte alignment. But there are plenty of examples of crashes not related to python+psyco. Proposal: add "-fno-tree-vectorize" to compilation options for 2.7/3.2. Warm 2.3/2.4/2.5/2.6/3.0/3.1 users. Or warm users compiling with GCC 4.5.0. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/_/_/_/ . _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQCVAwUBS+qpcZlgi5GaxT1NAQLAjgP/anZ5C2lED190++ffcluApF3ASF20iSnH t21ynHxrz2fgkPeOxeGRAqGEGCc3jZ0UuXchECcLLzFhI8WQS8K766EOgOKdwZLV WCt0ohWZ0FfsJZX4J5Y73x39uhjShbnl6SSek2uEvPi/tua/R4W/kVXrAZ0ZZR6/ vRqSUXpdolM= =5K+S -----END PGP SIGNATURE-----

PEP 7 updated
by Antoine Pitrou 13 May '10

13 May '10

Hello, The untabification of C files didn't produce any noticeable problem on the buildbots. I've updated PEP 7 with the mention that all C files should be 4-space indented, and removed the obsolete wording about some files being indented with tabs. Regards Antoine.

Python on Windows with CoApp
by Trent Nelson 12 May '10

12 May '10

Howdy folks, Quick e-mail at 34,000ft (aren't wifi-enabled flights great?) to mention a new initiative that's been started by Microsoft called CoApp (Common Opensource Application Publishing Platform). The aim is simple: make open source software rock on Windows ;-) It's probably easiest to think of it as a Microsoft-endorsed-but-community-run open source distribution for Windows, akin to all the various package managers for Linux distributions and ports/packages for the *BSDs. There are specific user and developer experiences we'll be addressing -- like making it easy to install and use open source software, or use it within your own project (open source or not). CoApp will affect Python in one of two ways. Once there's a clear-cut specification for open source projects to follow, Python can either decide to follow it, or not. The same applies to all open source packages, actually. For those that follow it, great! If not, no problem -- the plan is to shallow-fork such projects via launchpad and the CoApp community will take responsibility for getting releases of open source projects into CoApp shape. It's in its infancy at the moment -- it took the chap (Garrett Serack) who's spearheading it at Microsoft about six months to get it all signed off by the lawyers and platform/server VPs. So, for those of you out there who are Windows-inclined, now's a perfect time to get involved to help shape the direction of CoApp going forward. The website/wiki is http://coapp.org/ and the launchpad project site is http://launchpad.net/coapp (which is where the mailing list is hosted). We're actually having a 'CoApp Development Summit' tomorrow and Friday in Seattle (that Microsoft's graciously sponsored). The event will be accessible via Live Meeting for those that are interested: http://coapp.org/Project_Planning/CoApp_Design_and_Development_Summit Regards, Trent.
