If the object is an ExtensionClass, for example, the slot is not even
defined. So we must check that the type has the slot (implied by
HAVE_CLASS) before calling tp_init().
existed at the time atexit first got imported. That's a bug, and this
fixes it.
Also reworked test_atexit.py to test for this too, and to stop using
an "expected output" file, and to test what actually happens at exit
instead of just simulating what it thinks atexit will do at exit.
Bugfix candidate, but it's messy so I'll backport to 2.2 myself.
disaster too, so this change is here to stay. Beefed up the comments
and added some stats Andrew reported. Also a small change to the
macro body, to make it obvious how XXXROUNDUP(0) ends up returning 0.
See SF patch 578297 for context.
Not a bugfix candidate, as the functional changes here have already
been backported to the 2.2 line (this patch just improves clarity).
explicit comparison function case: use PyObject_Call instead of
PyEval_CallObject. Same thing in context, but gives a 2.4% overall
speedup when sorting a list of ints via list.sort(__builtin__.cmp).
Don't pass CREATE_NEW_CONSOLE to CreateProcess(), meaning our child process is in the same "console group" and therefore interrupted by the same Ctrl+C that interrupts the parent.
This gets us closer to consistent Ctrl+C behaviour on NT and Win9x. NT now reliably generates KeyboardInterrupt exceptions for NT when a file IO operation was aborted. Bugfix candidate
MSDN sample programs use it, apparently in error. The correct name
is WIN32_LEAN_AND_MEAN. After switching to the correct name, in two
cases more was needed because the code actually relied on things that
disappear when WIN32_LEAN_AND_MEAN is defined.
The test of httplib makes it difficult to maintain httplib. There are
two many idioms that pyclbr doesn't seem to understand, and I don't
understand how to update these tests to make them work.
Also remove commented out test of urllib2.
more spaces only crashed pdb.
While I was at it, cleaned up some style nits (spaces between function
and parenthesis, and redundant parentheses in if statement).
PyImport_ImportModule() is not guaranteed to return a module object.
When another type of object was returned, the PyModule_GetDict() call
return NULL and the subsequent GetItem() seg faulted.
Bug fix candidate.
arg tuple. This was suggested on c.l.py but afraid I can't find the msg
again for proper attribution. For
list.sort(cmp)
where list is a list of random ints, and cmp is __builtin__.cmp, this
yields an overall 50-60% speedup on my Win2K box. Of course this is a
best case, because the overhead of calling cmp relative to the cost of
actually comparing two ints is at an extreme. Nevertheless it's huge
bang for the buck. An additionak 20-30% can be bought by making the arg
tuple an immortal static (avoiding all but "the first" PyTuple_New), but
that's tricky to make correct since docompare needs to be reentrant. So
this picks the cherry and leaves the pits for Fred <wink>.
Note that this makes no difference to the
list.sort()
case; an arg tuple gets built only if the user specifies an explicit
sort function.
takes much longer to run in the context of the test suite than when run in
isolation. That's because it forces a large number of full collections,
which take time proportional to the total number of gc'ed objects in the
whole system.
But since the dangerous implementation trickery that caused this test to
fail in 2.0, 2.1 and 2.2 doesn't exist in 2.3 anymore (the trashcan
mechanism stopped doing evil things when the possibility for compiling
without cyclic gc was taken away), such an expensive test is no longer
justified. This checkin leaves the test intact, but fiddles the
constants to reduce the runtime by about a factor of 5.
