[issue1134] Parsing a simple script eats all of your memory

[Viktor Ferenczi]

Viktor Ferenczi added the comment:

Works fine (does nothing) with Python 2.4.4 and Python 2.5.1 under Windows, so 
this bug must be caused by some new code in Python3.0a1. The bug depends on the 
contents of the doc string. There's another strange behavior if you write the 
word "this" in the docstring somewhere. The docstring could be parsed as source 
code somehow and causes strange things to the new parser.

[issue1099] Mac compile fails with pydebug and framework enabled

[Elias Pipping]

Elias Pipping added the comment:

I can reproduce this problem on both an intel and a powerpc mac.

With '--with-pydebug --enable-framework --enable-universalsdk', the 
behavior is very much different:

On a powerpc mac, configure fails with
  'checking size of wchar_t...configure: error: cannot compute sizeof 
(wchar_t)'

On an intel mac, configure and make succeed; a test fails, though (which 
normally passes, e.g. when no arguments at all were passed to 
configure). The failing test is: test_xmlrpc.

[issue1765140] logging: delay_fh option and configuration kwargs

[Vinay Sajip]

Vinay Sajip added the comment:

Thanks for the patch. I think it would be simpler to just implement an
optional delay parameter in FileHandler and its subclasses: then the
configuration stuff need not be touched at all, since the delay
parameter can be specified in the configuration file. There would then
be no need for a callback or a file-opening closure: If delay is False
(the default), FileHandler would behave as it does now. If True, then
the open code in FileHandler's constructor would be deferred until the
time emit() was called on the instance.

Would this meet your needs?

[issue1125] bytes.split shold have same interface as str.split, or different name

[Stefan Sonnenberg-Carstens]

Stefan Sonnenberg-Carstens added the comment:

IMHO I also aggree that strings and bytes (list of bytes) should have
the same interface.
It is common sense that talking about strings most programmers think
of a list of bytes composing it (char *).
So the abbreviation should also hold true with python.
