_reconstructor (whose import here is a mystery to me).

checks in his changes to support this in cPickle.c.

if it exists in preference over __reduce__.  Now Tim can go implement this
in cPickle.c.

reasons:  importing module can fail, or the attribute lookup
module.name can fail.  We were giving the same error msg for
both cases, making it needlessly hard to guess what went wrong.
These cases give different error msgs now.

using super() for an instance in a metaclass situation.  Because the
class was a metaclass, the instance was a class, and hence the
PyType_Check() branch was taken.  But this branch didn't apply.  Make
it so that if this branch doesn't apply, the other branch is still
tried.  All tests pass.

the AIX problem with this test.

tp_as_number directly.

now have tp_as_number.  Check for nb_int or nb_float.

Change fatal errors during module initialization into RuntimeErrors.

There are some problems with this module, but the tool works for
simple tasks and no one else has volunteered a better code coverage
tool.  Should cleanup and document before the beta release.

Mostly rename WARN -> WARNING

Update tests (not in original patch)

arguments, and also does the right thing for the no argument case.

wouldn't serve a useful purpose anyway.

Use "l" as that *probably* makes more sense (at least to me it does :-)
And the test passes on the alpha.

Clean up the way IDLEfork handles termination of the subprocess, restore
ability to interrupt user code in Windows (so long as it's doing terminal
I/O).

1. Handle subprocess interrupts in Windows with an RPC message.
2. Run/F5 will restart the subprocess even if user code is running.
3. Restart the subprocess if the link is dropped.
4. Exit IDLE cleanly even during I/O.
4. In rpc.py, remove explicit calls to statelock, let the condition
   variable handle acquire() and release().

Remove the usage of PyErr_WarnExplicit() since this could cause
sensitive information from the source files to appear in e.g.
log files.

use METH_NOARGS instead

Remove PyArg_ParseTuple() for methods which take no args,
use METH_NOARGS instead

Fix off-by-1 error in normalize_line_endings():
  when *p == '\0' the NUL was copied into q and q was auto-incremented,
  the loop was broken out of,
  then a newline was appended followed by a NUL.
  So the function, in effect, was strcpy() but added two extra chars
  which was caught by obmalloc in debug mode, since there was only
  room for 1 additional newline.

Get test working under regrtest (added test_main).

"copy anything to a data fork based resource file" trick of macresource.
Fixes #688007.
