PIPE_BUF is not defined on Windows, and probably has no meaning there.
Anyway the subprocess module uses another way to perform non-blocking reads (with a thread)
was not always being done properly in some python types and extension
modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
all been updated to perform better checks and places in the code that
would previously leak memory on the error path when such an allocation
failed have been fixed.
The patch adds wrappers for the Linux epoll syscalls and the BSD kqueue syscalls. Thanks to Thomas Herve and the Twisted people for their support and help.
TODO: Finish documentation documentation
This patch checks if poll is broken when the select module is loaded instead
of doing so at configure-time. This functionality is only active on Mac OS X.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure. Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers. (In
fact, we expect that the compilers are all fixed eight years later.)
I'm leaving staticforward and statichere defined in object.h as
static. This is only for backwards compatibility with C extensions
that might still use it.
XXX I haven't updated the documentation.
type.__module__ behavior.
This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
Replace some tortuous code that was trying to be clever but forgot to
DECREF the key and value, by more longwinded but obviously correct
code.
(Inspired by but not copying the fix from SF patch #475033.)
the "#ifdef MS_WINDOWS" to "#ifdef SELECT_USES_HEAP" and by
setting SELECT_USES_HEAP when FD_SETSIZE > 1024.
The indirection seems useful since this subtly changes the path
that "normal" Windows programs take (where Timmie sez FD_SETSIZE =
512). If that's a problem for Windows, he has only one place to
change.
Include sys/poll.h if it was found by the configure script. The OpenGroup
spec says poll.h is the correct header file to use, so that file is
preferred.
