I chose IOError rather than EnvironmentError as the base class since
socket objects are often used as transparent duck typed file objects
in code already prepared to deal with IOError exceptions.

also a minor fix:

 urllib2 - fix a couple places where IOError was raised rather than URLError.
           for better or worse, URLError already inherits from IOError so
           this won't break any existing code.

 test_urllib2net - replace bad ftp urls.

backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

from Linux's.  Just fix the build for now but the code doesn't
support the complete capability of HCI on FreeBSD yet.

socket.recvfrom, which caused an ugly crash.

Will backport.

Will backport to 2.5.

a socket operation on a socket with a timeout, the exception will be
caught correctly.  Previously, the exception was not caught.

differs from both Linux and FreeBSD. Accepted by Neal Norwitz.

means that select() on sockets > FD_SETSIZE (typically 1024) work again.
The patch makes sockets use poll() internally where available.

- update header checks, using autoconf
- provide dummies for getenv, environ, and GetVersion
- adjust MSC_VER check in socketmodule.c

- Following Guido's comments, renamed

  * pack_to -> pack_into
  * recv_buf -> recv_into
  * recvfrom_buf -> recvfrom_into

- Made fixes to _struct.c according to Neal Norwitz comments on the checkins
  list.

- Converted some ints into the appropriate -- I hope -- ssize_t and size_t.

Use Py_UnpackTuple instead of PyArg_ParseTuple where possible.

Fix refleak in exceptions.

* Added socket.recv_buf() and socket.recvfrom_buf() methods, that use the buffer
  protocol (send and sendto already did).

* Added struct.pack_to(), that is the corresponding buffer compatible method to
  unpack_from().

* Fixed minor typos in arraymodule.

AF_PACKET cases in getsockaddrarg were missing their own checks for
tuple-ness of the address argument, which means a confusing SystemError was
raised by PyArg_ParseTuple instead.

This patch causes several symbols in the socket and posix module to be weakly
linked on OSX and disables usage of ftime on OSX. These changes make it possible
to use a binary build on OSX 10.4 on a 10.3 system.

is larger than FD_SETSIZE.

This can only be acheived with ulimit -n SOME_NUMBER_BIGGER_THAN_FD_SETSIZE
which is typically only available to root.  Since this wouldn't normally
be run in a test (ie, run as root), it doesn't seem too worthwhile to
add a normal test.  The bug report has one version of a test.  I've
written another.  Not sure what the best thing to do is.

Do the check before calling internal_select() because we can't set
an error in between Py_BEGIN_ALLOW_THREADS and Py_END_ALLOW_THREADS.
This seemed the clearest solution, ie handle before calling internal_select()
rather than inside.  Plus there is at least one place outside
of internal_select() that needed to be handled.

Will backport.

Probably should be backported.
