Lesson learned: kids should not be allowed to use API's starting
with an underscore :-/
zipimport in 2.3a1 is even more broken than I thought: I attemped
to _PyString_Resize a string created by PyString_FromStringAndSize,
which fails for strings with length 0 or 1 since the latter returns
an interned string in those cases. This would cause a SystemError
with empty source files (and no matching pyc) in the zip archive.
I rewrote the offending code to simply allocate a new buffer and
avoid _PyString_Resize altogether.
Added a test that would've caught the problem.
because the test file, msg_26.txt which has \r\n line endings, was
getting munged by cvs, which knows to do line ending conversions for
text files. But we want \r\n to be preserved on all platforms, so we
cvs admin'd the file to be -kb (binary), which means we have to open
the file in binary mode to preserve these line ends. Hopefully this
will be the end of the thrashing on this issue (but probably not).
Test passes on *nix now, and Tim confirms it passes on Windows. We'll
leave it to Jack to test MacOS.
(or None) now. In 2.3a1 they could also return an int or long, but that
was an unhelpfully redundant leftover from an earlier version wherein
they couldn't return a timedelta. TOOWTDI.
PC/python_nt.rc sets up the DLL version resource (displayed when you
right-click on the DLL and select Properties).
PCbuld/python20.wse sets up the installer version resource (displayed
when you right-click on the installer .exe and select Properties). Turns
out this one hadn't been updated since 2001 <frown>!
On Windows, it was very common to get microsecond values (out of
.today() and .now()) of the form 480999, i.e. with three trailing
nines. The platform precision is .001 seconds, and fp rounding
errors account for the rest. Under the covers, that 480999 started
life as the fractional part of a timestamp, like .4809999978.
Rounding that times 1e6 cures the irritation.
Confession: the platform precision isn't really .001 seconds. It's
usually worse. What actually happens is that MS rounds a cruder value
to a multiple of .001, and that suffers its own rounding errors.
A tiny bit of refactoring added a new internal utility to round
doubles.
Added the logging package. In the meantime, Neal Norwitz added a
test_logging.py to the std test suite, which would have caught this
oversight in the Windows installer.
the test set as it only tested with a zip archive in the current directory,
but it doesn't work at all for packages when the zip archive was specified
as an absolute path. It's a real embarrassing bug: a strchr call should
have been strrchr; fever apparently implies dyslexia.
Second stupid bug: the zipimport test failed with a name error
__importer__ (which I had renamed to __loader__ everywhere but here).
I would've sworn I ran the test after that change but that can't be true.
What I don't understand that noone reported a failing test_zipimport.py
before the release of 2.3a1.
