subtype_dealloc().
When call_finalizer() failed, it would return without going through
the trashcan end macro, thereby unbalancing the trashcan nesting level
counter, and thereby defeating the test case (slottrash() in
test_descr.py). This in turn meant that the assert in the GC_UNTRACK
macro wasn't triggered by the slottrash() test despite a bug in the
code: _PyTrash_destroy_chain() calls the dealloc routine with an
object that's untracked, and the assert in the GC_UNTRACK macro would
fail on this; but because of an earlier test that resurrects an
object, causing call_finalizer() to fail and the trashcan nesting
level to be unbalanced, so _PyTrash_destroy_chain() was never called.
Calling the slottrash() test in isolation *did* trigger the assert,
however.
So the fix is twofold: (1) call the GC_UnTrack() function instead of
the GC_UNTRACK macro, because the function is safe when the object is
already untracked; (2) when call_finalizer() fails, jump to a label
that exits through the trashcan end macro, keeping the trashcan
nesting balanced.
and this broke a Zope "pipelining" test which read multiple responses
from the same connection (this attaches a new file object to the
socket for each response). Added a test for this too.
(I want to do some code cleanup too, but I thought I'd first fix
the problem with as little code as possible, and add a unit test
for this case. So that's what this checkin is about.)
in stead of prepending it, which messes up "import * from".
- A few ascii()s added again.
- Changed the getbaseclasses a little, but it still isn't perfect.
This patch makes inheritance for OSA classes work. The implementation is a
bit convoluted, but I don't immedeately see a simpler way of doing it.
I added calls to ascii() everywhere we output strings that may contain
non-ascii characters (Python has gotten very picky since the encoding
patch:-).
I also removed Donovan's different way of opening resource files: I don't
seem to need it.
WSAEWOULDBLOCK, the second connect() attempt appears to yield WSAEISCONN
on Win98 but WSAEINVAL on Win2K. So accept either as meaning "yawn,
fine". This allows test_socket to succeed on my Win2K box (which it
already did on my Win98SE box).
This is inspired by SF patch 581742 (by Jonathan Hogg, who also
submitted the bug report, and two other suggested patches), but
separates the non-GC case from the GC case to avoid testing for GC
several times.
Had to fix an assert() from call_finalizer() that asserted that the
object wasn't untracked, because it's possible that the object isn't
GC'ed!
