blocked in select(), this will raise select.error with errno set to
EINTR. The except clauses correctly ignores this error, but the rest
of the logic will then call read() for all objects in select's *input*
list of read file descriptors. Then when an object's read_handler()
is naive, it will call recv() on its socket, which will raise an
IOError, and then asyncore decides to close the socket. To fix this,
we simply return in this case.
Backport candidate.

topdir = "Lib/distutils"
* bcppcompiler.py
(BCPPCompiler.create_static_lib): Fixed prototype, removing extra_preargs
and extra_postargs parameters. Included target_lang parameter.
(BCPPCompiler.link): Included target_lang parameter.
* msvccompiler.py
(MSVCCompiler.create_static_lib): Fixed prototype, removing extra_preargs
and extra_postargs parameters. Included target_lang parameter.
(MSVCCompiler.link): Included target_lang parameter.
* ccompiler.py
(CCompiler): New language_map and language_order attributes, used by
CCompiler.detect_language().
(CCompiler.detect_language): New method, will return the language of
a given source, or list of sources. Individual source language is
detected using the language_map dict. When mixed sources are used,
language_order will stablish the language precedence.
(CCompiler.create_static_lib, CCompiler.link, CCompiler.link_executable,
CCompiler.link_shared_object, CCompiler.link_shared_lib):
Inlcuded target_lang parameter.
* cygwinccompiler.py
(CygwinCCompiler.link): Included target_lang parameter.
* emxccompiler.py
(EMXCCompiler.link): Included target_lang parameter.
* mwerkscompiler.py
(MWerksCompiler.link): Included target_lang parameter.
* extension.py
(Extension.__init__): New 'language' parameter/attribute, initialized
to None by default. If provided will overlap the automatic detection
made by CCompiler.detect_language(), in build_ext command.
* sysconfig.py
(customize_compiler): Check Makefile for CXX option, and also the
environment variable CXX. Use the resulting value in the 'compiler_cxx'
parameter of compiler.set_executables().
* unixccompiler.py
(UnixCCompiler): Included 'compiler_cxx' in executables dict, defaulting
to 'cc'.
(UnixCCompiler.create_static_lib): Included target_lang parameter.
(UnixCCompiler.link): Included target_lang parameter, and made
linker command use compiler_cxx, if target_lang is 'c++'.
* command/build_ext.py
(build_ext.build_extension): Pass new ext.language attribute
to compiler.link_shared_object()'s target_lang parameter. If
ext.language is not provided, detect language using
compiler.detect_language(sources) instead.
* command/config.py
(config._link): Pass already available lang parameter as target_lang
parameter of compiler.link_executable().
/* this is harder to get right than you might think */
angered some God somewhere. After noticing
>>> range(5000000)[slice(96360, None, 439)]
[]
I found that my cute test for the slice being empty failed due to
overflow. Fixed, and added simple test (not the above!).
_locale.getdefaultlocale. Guessing a leading underscore was intended,
but don't really understood this stuff (locale looks like Spanish for
the opposite of global to me <wink>).
customize_compiler() now looks at various environment variables and uses
their values to override the configured C compiler/preprocessor/linker
binary and flags.
Fixed the signed/unsigned confusions when dealing with files >= 2GB.
4GB is still a hard limitation of the gzip file format, though.
Testing this was a bitch on Win98SE due to frequent system freezes. It
didn't freeze while running gzip, it kept freezing while trying to *create*
a > 2GB test file! This wasn't Python's doing. I don't know of a
reasonable way to test this functionality in regrtest.py, so I'm not
checking in a test case (a test case would necessarily require creating
a 2GB+ file first, using gzip to zip it, using gzip to unzip it again,
and then compare before-and-after; so >4GB free space would be required,
and a loooong time; I did all this "by hand" once).
Bugfix candidate, I guess.
whether the Distutils being used supports a particularly capability.
(This idea was originally suggested by Juergen Hermann as a method
on the Distribution class. I think it makes more sense as a
function in core.py, and that's what this patch implements.)
On HPUX, Solaris, Tru64 (Dec UNIX), and IRIX (I think),
O_NONBLOCK is the POSIX version of non-blocking I/O
which is what we want.
On Linux and FreeBSD (at least), O_NONBLOCK and O_NDELAY are the same.
So this change should have no negative effect on those platforms.
Tested on Linux, Solaris, HPUX.
Thanks to Anders Qvist for diagnosing this problem.
