Remove the log file after we are done with it. This should clean up after

Simply commented it out, and then test_hotshot passes on Windows.
Leaving to Fred to fix "the right way" (it seems to be a feature of

inherit_slots(): tp_as_buffer was getting inherited as if it were a
method pointer, rather than a pointer to a vector of method pointers. As
a result, inheriting from a type that implemented buffer methods was
ineffective, leaving all the tp_as_buffer slots NULL in the subclass.

calculate the proper dispatch slot and propagate the change to all
subclasses. Because of multiple inheritance, there's no easy way to
avoid always recursing down the tree of subclasses. Who cares?
(There's more to do, but this works. There's also a test for this now.)
Try to be systematic about dealing with socket and ssl exceptions in
FakeSocket.makefile(). The previous version of the code caught all
ssl errors and treated them as EOF, even though most of the errors
don't mean EOF.
An SSL error can mean on of three things:
1. The SSL/TLS connection was closed.
2. The operation should be retried.
3. An error occurred.
Also, if a socket error occurred and the error was EINTR, retry the
call. Otherwise, it was a legitimate error and the caller should
receive the exception.

assigning it as a string to the container's payload. This can be much
faster when you're only interested in a message's header.
value, so the programmer will have to catch OverflowError. I'm not sure
what /F's perspective is on this. Perhaps it should be caught and mapped to
an xmlrpclib-specific exception. None of the other type-specific dump
methods seem to do any exception handling though.

Rewrote the calibration docs.
Modern boxes are so friggin' fast, and a profiler event does so much work
anyway, that the cost of looking up an instance vrbl (the bias constant)
per profile event just isn't a big deal.
the problem that slots weren't inherited properly. override_slots()
no longer exists; in its place comes fixup_slot_dispatchers() which
does more and different work and is table-based. (Eventually I want
this table also to replace all the little tab_foo tables.)
Also add a wrapper for __delslice__; this required a change in
test_descrtut.py.

actual run of the profiler, instead of timing a simplified simulation of
part of what the profiler does. It computes a constant about 60% higher
on my Win98SE box than the old method, and the new constant appears much
more realistic. Deleted the undocumented simple(), instrumented(), and
profiler_simulation() methods (which existed only to support the previous
calibration method).
this type of test fails, vereq() does a better job of reporting than
verify().
Change vereq(x, y) to use "not x == y" rather than "x != y" -- it
makes a difference is some overloading tests.
Most of this code was old enough to vote. Examples of cleanups:
+ Backslashes were used for line continuation even inside unclosed
bracket structures, from back in the days that was still needed.
+ There was no use of % formats, and e.g. the old fpformat module was
still used to format floats "by hand" in conjunction with rjust().
+ There was even use of a do-nothing .ignore() method to tack on to the
end of a chain of method calls, else way back when Python would print
the non-None result (as it does now in an interactive session -- it
*used* to do that in batch mode too).
+ Perhaps controversial (although I can't imagine why for real <wink>),
used augmented assignment where helpful. Stuff like
self.total_calls = self.total_calls + other.total_calls
is just plain harder to follow than
self.total_calls += other.total_calls
seriously wrong. This started out by just fixing the docs, but then it
occurred to me that the doc confusion propagated into misleading vrbl names
too, so I also renamed those to match reality. As a result, INO the time
computations are much easier to understand now (within the limitations of
vast quantities of 3-character names <wink>).
many types were subclassable but had a xxx_dealloc function that
called PyObject_DEL(self) directly instead of deferring to
self->ob_type->tp_free(self). It is permissible to set tp_free in the
type object directly to _PyObject_Del, for non-GC types, or to
_PyObject_GC_Del, for GC types. Still, PyObject_DEL was a tad faster,
so I'm fearing that our pystone rating is going down again. I'm not
sure if doing something like
void xxx_dealloc(PyObject *self)
{
if (PyXxxCheckExact(self))
PyObject_DEL(self);
else
self->ob_type->tp_free(self);
}
is any faster than always calling the else branch, so I haven't
attempted that -- however those types whose own dealloc is fancier
(int, float, unicode) do use this pattern.
This patch allows ConfigParser.getboolean() to interpret TRUE,
FALSE, YES, NO, ON and OFF instead just '0' and '1'.
While just allowing '0' and '1' sounds more correct users often
demand to use more descriptive directives in configuration
files. Instead of forcing every programmer do brew his own
solution a system should include the batteries for this.
[My modification to the patch is a slight rewording of the docstring
and use of lowercase instead of uppercase templates. The code is
still case sensitive. GvR.]

For a dynamically constructed type object, fill in the tp_doc slot with
a copy of the argument dict's "__doc__" value, provided the latter exists
and is a string.
NOTE: I don't know what to do if it's a Unicode string, so in that case
tp_doc is left NULL (which shows up as Py_None if you do Class.__doc__).
Note that tp_doc holds a char*, not a general PyObject*.
it deals correctly with some anomalous cases; according to this test
suite I've fixed it right.
The anomalous cases had to do with 'exception' events: these aren't
generated when they would be most helpful, and the profiler has to
work hard to recover the right information. The problems occur when C
code (such as hasattr(), which is used as the example here) calls back
into Python code and clears an exception raised by that Python code.
Consider this example:
def foo():
hasattr(obj, "bar")
Where obj is an instance from a class like this:
class C:
def __getattr__(self, name):
raise AttributeError
The profiler sees the following sequence of events:
call (foo)
call (__getattr__)
exception (in __getattr__)
return (from foo)
Previously, the profiler would assume the return event returned from
__getattr__. An if statement checking for this condition and raising
an exception was commented out... This version does the right thing.
test for modifying __getattr__ works, now that slot_tp_getattr_hook
zaps the slot if there's no hook. Added an XXX comment with a ref
back to slot_tp_getattr_hook.
Taught doctest about static methods, class methods, and property docstrings
in new-style classes. As for inspect.py/pydoc.py before it, the new stuff
needed didn't really fit into the old architecture (but was less of a
strain to force-fit here).
New-style class docstrings still aren't found, but that's the subject
of a different bug and I want to fix that right instead of hacking around
it in doctest.
instances).
Also added GC support to various auxiliary types: super, property,
descriptors, wrappers, dictproxy. (Only type objects have a tp_clear
field; the other types are.)
One change was necessary to the GC infrastructure. We have statically
allocated type objects that don't have a GC header (and can't easily
be given one) and heap-allocated type objects that do have a GC
header. Giving these different metatypes would be really ugly: I
tried, and I had to modify pickle.py, cPickle.c, copy.py, add a new
invent a new name for the new metatype and make it a built-in, change
affected tests... In short, a mess. So instead, we add a new type
slot tp_is_gc, which is a simple Boolean function that determines
whether a particular instance has GC headers or not. This slot is
only relevant for types that have the (new) GC flag bit set. If the
tp_is_gc slot is NULL (by far the most common case), all instances of
the type are deemed to have GC headers. This slot is called by the
PyObject_IS_GC() macro (which is only used twice, both times in
gcmodule.c).
I also changed the extern declarations for a bunch of GC-related
functions (_PyObject_GC_Del etc.): these always exist but objimpl.h
only declared them when WITH_CYCLE_GC was defined, but I needed to be
able to reference them without #ifdefs. (When WITH_CYCLE_GC is not
defined, they do the same as their non-GC counterparts anyway.)
- The test for deepcopy() in pickles() was indented wrongly, so it got
run twice (one for binary pickle mode, one for text pickle mode; but
the test doesn't depend on the pickle mode).
- In verbose mode, show which subtest (pickle/cPickle/deepcopy, text/bin).
in run_test() referenced two non-existent variables, and in
non-verbose mode, the tests didn't report the actual number, when it
differed from the expected number. Fixed this.
Also added an extra call to gc.collect() at the start of test_all().
This will be needed when I check in the changes to add GC to new-style
classes.
