the string one line at a time. The resulting code is (in my opinion,
anyway), much easier to read. In the process, I found and fixed a
bug in the orginal parser's line numbering in error messages (it was
inconsistant between 0-based and 1-based). Also, check for missing
blank lines after the prompt on all prompt lines, not just PS1 lines
(test added).
Added XXX comment about why the undocumented PyRange_New() API function
is too broken to be worth the considerable pain of repairing.
Changed range_new() to stop using PyRange_New(). This fixes a variety
of bogus errors. Nothing in the core uses PyRange_New() now.
Documented that xrange() is intended to be simple and fast, and that
CPython restricts its arguments, and length of its result sequence, to
native C longs.
Added some tests that failed before the patch, and repaired a test that
relied on a bogus OverflowError getting raised.
This got slammed in when find() was fixed to stop grabbing doctests
from modules imported *by* the module being tested. Such tests cannot
be expected to succeed, since they'll be run with the current module's
globals. Dozens of Zope3 doctests were failing because of that.
It wasn't clear why ignore_imports got added then. Maybe it's because
some existing tests failed when the change was made. Whatever, it's
a Bad Idea so it's gone now.
The only use of it was exceedingly obscure, in test_doctest's "Duplicate
Removal" test. It was "needed" there because, as an artifact of running
a doctest inside a doctest, the func_globals of functions compiled in
the second-level doctest don't match the module globals, and so the
test-finder believed these functions were from a foreign module and
skipped them. But that took a long time to figure out, and I actually
understand some of this stuff <0.9 wink>.
That problem was resolved by moving the source code for the second-level
doctest into an actual module (test/doctest_aliases.py).
The only remaining difficulty was that the test for the deprecated
Tester.rundict() then failed, because the test finder doesn't take
module=None at face value, trying to guess which module the user really
intended then. Its guess wasn't appropriate for what Tester.rundict
needs when module=None is given to *it*, which is "no, there is no
module here, and I mean it". So now passing module=False means exactly
that. This is hokey, but ignore_imports=False was really a hack to worm
around that there was no way to tell the test-finder that module=None
*sometimes* means what it says. There was no use case for the combination
of passing a real module with ignore_imports=False.
Ripped out the docs for the new DocTestFinder's namefilter argument,
and renamed it to _namefilter; this only existed to support isprivate.
Removed the new DocTestFinder's objfilter argument. No point adding
more cruft to a broken filtering design.
That's the title of the report, but the hole was probably plugged since
Python 2.0. See corresponding checkin to PC/getpathp.c: a crucial
precondition for joinpath() was neither documented nor verified, and there
are so many callers with so many conditional paths that no "eyeball
analysis" is satisfactory. Now Python dies with a fatal error if the
precondition isn't satisfied, instead of allowing a buffer overrun.
NOT TESTED! The Windows version of the patch was, but not this one. I
don't feel like waiting for someone to notice the patch I attached to the
bug report. If it doesn't compile, sorry, but fix it <wink>. If it
does compile, it's "obviously correct".
hack: it would resize *interned* strings in-place! This occurred because
their reference counts do not have their expected value -- stringobject.c
hacks them. Mea culpa.
This test is insanely slow, so it requires a resource. On my machine,
it also appears to dump core. I think the problem is a stack
overflow, but haven't been able to confirm.
interning were not clear here -- a subclass could be mutable, for
example -- and had bugs. Explicitly interning a subclass of string
via intern() will raise a TypeError. Internal operations that attempt
to intern a string subclass will have no effect.
Added a few tests to test_builtin that includes the old buggy code and
verifies that calls like PyObject_SetAttr() don't fail. Perhaps these
tests should have gone in test_string.
This was probably fixed in rev 1.32 of getpath.c, but there are so
many paths thru the code that invoke joinpath() it's not at all
obvious that it *is* fixed. It doesn't help confidence that a crucial
precondition for calling joinpath() was neither documented nor verified.
It is now, and joinpath() will barf with a fatal error now rather than
overrun the buffer, if the precondition isn't met.
Note that this patch only changes the Windows flavor. I attached another
patch to the bug report for the POSIX flavor (which I can't test
conveniently).
[ 991812 ] PyArg_ParseTuple can miss errors with warnings as exceptions
as suggested in the report.
This is definitely a 2.3 candidate (as are most of the checkins I've
made in the last month...)
The change to use the newer httplib interface admitted the possibility
that we'd get an HTTP/1.1 chunked response, but the code didn't handle
it correctly. The raw socket object can't be pass to addinfourl(),
because it would read the undecoded response. Instead, addinfourl()
must call HTTPResponse.read(), which will handle the decoding.
One extra wrinkle is that the HTTPReponse object can't be passed to
addinfourl() either, because it doesn't implement readline() or
readlines(). As a quick hack, use socket._fileobject(), which
implements those methods on top of a read buffer. (suggested by mwh)
Finally, add some tests based on test_urllibnet.
Thanks to Andrew Sawyers for originally reporting the chunked problem.
