Null bytes in source code
by Greg Ward 25 Sep '01

25 Sep '01

Weird: in the current CVS, certain files in Lib have null bytes (ASCII 0) in them. Install-time byte-compilation complains about this, so "make install" fails. Eg. here's what "less Lib/reconvert.py" shows me me: ------------------------------------------------------------------------ #! /usr/bin/env python1.5 r"""Convert old ("regex") regular expressions to new syntax ("re"). When imported as a module, there are two functions, with their own strings: convert(s, syntax=None) -- convert a regex regular expression to re syntax ^@^@^@^@te(s) -- return a quoted string literal [...] ------------------------------------------------------------------------ Those "^@"'s are really ASCII 0 -- I checked with "od -c". Am I on drugs here? -- Greg Ward - software developer gward(a)mems-exchange.org MEMS Exchange http://www.mems-exchange.org

A baffler in test_repr
by Tim Peters 24 Sep '01

24 Sep '01

test_repr (very) recently started failing for me, on Windows, but only when doing a full run of the test suite. Same symptom in release or debug builds. test_repr does not fail when run alone, and regardless of whether run directly from cmdline, or via "regrtest test_repr". Here's the failure: test_repr test test_repr failed -- Traceback (most recent call last): File "../lib/test\test_repr.py", line 156, in test_descriptors self.failUnless(repr(x).startswith('<staticmethod object at 0x')) File "C:\CODE\PYTHON\lib\unittest.py", line 256, in failUnless if not expr: raise self.failureException, msg AssertionError This is the code that's failing: class C: def foo(cls): pass x = staticmethod(C.foo) self.failUnless(repr(x).startswith('<staticmethod object at 0x')) By putting import sys; print >> sys.stderr, '*' * 30, repr(x) before the last line, when it fails repr(x) is actually: <staticmethod instance at 0x017E26C0> when it fails (although the address varies, of course). How can it be either "an object" or "an instance" depending on how the test is run? A staticmethod doesn't contain enough data that it's possible to forget to initialize any of it <0.7 wink>.

I'm not getting my python-checkins mail. The messages are getting archived, but I don't get them in my inbox. Does anybody else still get them? Barry, can you see if there's a blockage somewhere? --Guido van Rossum (home page: http://www.python.org/~guido/)

Re: 2.2a1: classmethod() and class attributes

I don't find the arguments about changing __class__ to be particularly persuasive, but I think the above code *is* closely related to standard Python idioms that should work by default. +1 on changing __dynamic__ or at least enabling some kind of class variable mutability by default. -- --- Aahz (@pobox.com) Hugs and backrubs -- I break Rule 6 <*> http://www.rahul.net/aahz/ Androgynous poly kinky vanilla queer het Pythonista I don't really mind a person having the last whine, but I do mind someone else having the last self-righteous whine.

test_string, test_unicode fail
by Guido van Rossum 20 Sep '01

20 Sep '01

Today, test_string and test_unicode have started to fail. I'm suspicious that this is the result of changes Marc-Andre checked in to make unicode() behave more like str(). A little investigation (not that the string test suite makes this easy :-( ) shows that line 133 of string_tests.py checks to make sure that '.'.join('a', u'b', 3) raise an exception. But it now silently casts the 3 to u'3', so the result is u'a.b.3'. Is this really an good idea? Was it an intended side effect? Also, Marc-Andre, please run the full test suite and check its results before checking in changes like this. --Guido van Rossum (home page: http://www.python.org/~guido/)
