test_asyncore fails intermittently on Darwin
by Hasan Diwan July 26, 2007

July 26, 2007

test_asyncore fails intermittently on Darwin in trunk rev 56558; it seems a matter of executing the test too fast and not waiting for the TCP_WAIT state to expire. I think somebody encountered this problem previously with another module (socket_server) and I'm unsure how that was sorted. -- Cheers, Hasan Diwan <hasan.diwan(a)gmail.com>

interaction between locals, builtins and except clause
by Lisandro Dalcin July 26, 2007

July 26, 2007

Porting to Py3K, I modified a function like the followin, using a trick for it working in Py2.x . def __iter__(self): if self == _mpi.INFO_NULL: return try: range = xrange except: pass nkeys = _mpi.info_get_nkeys(self) for nthkey in range(nkeys): yield _mpi.info_get_nthkey(self, nthkey) However, I've got in my unittests (running with py3k) ERROR: testPyMethods (__main__.TestInfo) -------------------------------------------… [View More]

Floating point test_pow failure on the alpha Debian buildbot
by Nick Coghlan July 26, 2007

July 26, 2007

test_pow is failing on the alpha Debian buildbot, complaining that a negative number can't be raised to a fractional power. Now, to work around some bugs in platform implementations of math.fpow(), pow() does its own check to see if the exponent is an integer. The way pow() does that check is to try "iw == floor(iw)", so to see why the exception was being triggered, I put a couple of extra output lines into the test and got: *** Number: 1.2299999999999999e+167 *** Floor: 1.… [View More]

Terminology of "Iterable" and "Iterator"
by Calvin Spealman July 26, 2007

July 26, 2007

I got into a discussion about this, which made me think it would make sense to formalize a distinction between "iterable" and "iterator". To nearly any python developer I talk with, we can define them as: iterable - An object which can be passed to the built-in iter() function, which returns an iterator. iterator - An object with a .next() method, which is used to invoke the iteration. An iterator _should_ also be an iterable, and will nearly always return itself as its own iterator. Now, … [View More]

Failure on assorted buildbots - Address already in use
by Nick Coghlan July 25, 2007

July 25, 2007

A lot of the buildbots are red at the moment, which makes it harder to tell if a checkin broke anything new on other platforms. I've checked in a change to test_resource that should hopefully make some of the Debian buildbots happier, but several of the other buildbots are reporting a variety of "Address already in use" errors in the subthreads created by test_urllib2. Anyone have any ideas? Cheers, Nick. -- Nick Coghlan | ncoghlan(a)gmail.com | Brisbane, Australia -------------… [View More]

-z, -i and -m, maybe bug in runpy?
by Phillip J. Eby July 25, 2007

July 25, 2007

While trying to get my -z replacement patch to work, I stumbled across a bug in the -m implementation (and in runpy). It seems that when you run the code of a -m module, it is *not* run in the __main__ module namespace! So even though __name__=='__main__', globals() is not sys.modules['__main__'].__dict__. This seems wrong to me. Does anybody know why runpy doesn't actually run the code in the target module? One consequence of this is that the -i option is much less useful when you … [View More]
