setdefault() the empty string. In setdefault(), use + to join the value
to create the entry for the headers attribute so that TypeError is raised
if the value is of the wrong type.
When regrtest.py finds an attribute "test_main" in a test it imports,
regrtest runs the test's test_main after the import. test_threaded_import
needs this else the cross-thread import lock prevents it from making
progress. Other tests can use this hack too, but I doubt it will ever be
popular.
This should be faster.
This means:
(1) "for line in file:" won't work if the xreadlines module can't be
imported.
(2) The body of "for line in file:" shouldn't use the file directly;
the effects (e.g. of file.readline(), file.seek() or even
file.tell()) would be undefined because of the buffering that goes
on in the xreadlines module.
for loading modules from the application resource fork stopped working
when sys.path component normalization was implemented. Comparison
of sys.path components is now done by FSSpec in stead of by pathname.
ICK ALERT: read the long comment block before run_the_test(). It was
almost impossible to get this to run without instant deadlock, and the
solution here sucks on several counts. If you can dream up a better way,
let me know!
numbers that display nicely after repr(). From much doctest experience
with the same trick, I believe people find examples with simple fractions
easier to understand too: they can usually check the results in their
head, and so feel confident about what they're seeing. Not even I get a
warm feeling from a result that looks like 70330.345024097141 ...
UTF-16 codec will now interpret and remove a *leading* BOM mark. Sub-
sequent BOM characters are no longer interpreted and removed.
UTF-16-LE and -BE pass through all BOM mark characters.
These changes should get the UTF-16 codec more in line with what
the Unicode FAQ recommends w/r to BOM marks.
basically accept <!...> where the dots can be single- or double-quoted
strings or any other character except >.
Background: I found a real-life example that failed to parse with
the old assumption: http://www.opensource.org/licenses/jabberpl.html
contains a few constructs of the form <![if !supportLists]>...<![endif]>.
indicating whether the entry was extracted from a docstring or not.
write(): If any of the locations of a string appearance came from a
docstring, add a comment such as
#. docstring
before the references (after a suggestion by Martin von Loewis).
floating point numbers in an interactive example.
Added comment to help explain control flow in the example code showing
how to check if a number is prime.
This closes SF bugs 419434 and 424552.
Two exceedingly unlikely errors in dictresize():
1. The loop for finding the new size had an off-by-one error at the
end (could over-index the polys[] vector).
2. The polys[] vector ended with a 0, apparently intended as a sentinel
value but never used as such; i.e., it was never checked, so 0 could
have been used *as* a polynomial.
Neither bug could trigger unless a dict grew to 2**30 slots; since that
would consume at least 12GB of memory just to hold the dict pointers,
I'm betting it's not the cause of the bug Fred's tracking down <wink>.
