[issue5251] contextlib.nested inconsistent with, well, nested with statements due exceptions raised in __enter__

New submission from James William Pye : Basically, nested() doesn't seem to be consistent with explicitly nested with-statements when an exception is thrown in a CM's __enter__. Consider a pair of nested CMs, the inner __enter__ raises an exception trapped by the outer. In the si

[issue1195571] simple callback system for Py_FatalError

James William Pye added the comment: I had actually forgotten that this was still open. Anything I can do to help speed this along? In case nobody remembers, the purpose of this was to provide a facility to embedded applications that allows for a more graceful shutdown in fatal error

[issue5283] setting __class__ in __del__ is bad. mmkay. negative ref count! kaboom!

New submission from James William Pye : I found this bug by misplacing a line of a code. Yes, I was doing naughty things, but in the case of the class that led to the discovery, it was inadvertent. :P class something_else(object): pass class foo(object): def __del__(self): self.__class__

[issue2698] Extension module build fails for MinGW: missing vcvarsall.bat

James William Pye added the comment: Seeing this in 3.1 when I try to compile with mingw32 under wine: "error: Unable to find vcvarsall.bat" --compiler=mingw32 works in 3.0. I assume it's related to this bug? -- nosy: +jwp versio

[issue5251] contextlib.nested inconsistent with, well, nested with statements due exceptions raised in __enter__

James William Pye added the comment: I tested the attached script against v2. It further identifies consistencies between nested with-statements and nested() that should exist(and do in v2). It answers the question: what is the effect of a SkipStatement exception on another, outer CM? with

[issue1195571] simple callback system for Py_FatalError

James William Pye added the comment: Would it be possible to require the embedding application to define the Py_FatalError symbol? Admittedly, it would be nice to not have the callback installation code. =\ -- ___ Python tracker <h

[issue1195571] simple callback system for Py_FatalError

James William Pye added the comment: I guess it seemed so unlikely that (C) extensions should be installing the callback that installation should be restricted pre-Py_Initialize(); the area completely controlled by the embedding app. However, I have no strong attachment to that
