Bug description: [patch] Add TCP_NODELAY constant for socket_{get,set}_option
Description:
------------
C-level TCP function setsockopt allows users of TCP sockets to set the
TCP_NODELAY flag. This flag disable's the typically default use of Nagle's
Algorithm[1] on a TCP socket.
1: http://en.wikipedia.org/wiki/Nagle%27s_algorithm
Nagle's Algorithm is bad for protocols like the extremely brief one spoken
by PHP/Java Bridge. This patch is inspired by my use of PJB on FreeBSD
which does not automatically set TCP_NODELAY on localhost connections.
PHP does not expose this constant, although it is valid for the sockets
library as socket_set_option is a straightforward wrapper around
setsockopt.
Here is a trivial patch against PHP 5.2.5 to add the PHP constant
TCP_NODELAY. I have tested this on FreeBSD 7.0 + PHP 5.2.5. Patch is
quite simple so should apply fine against 5.3 / 6 with just a line offset.
Constant is the same on Linux so will work fine there; am not sure about
win32. Happy to test other versions and platforms if necessary.
