FastCGI unix sockets support patch

Hi Rostislav,

PHP HEAD and PHP_5_1 (5.1.3) don't use libfcgi any more.
They use simplest and smallest replacement library.

Please look into CVS code and provide a patch for it (if necessary).

Thanks. Dmitry.

Subject: [PHP-DEV] FastCGI unix sockets support patch

Hi,

According to a 'php -h' output of php-cgi 5.1.2 the FastCGI
can be used only by TCP/IP:

-b address:port|<port> Bind Path for external FASTCGI Server mode

But according to the code FastCGI could also be used by UNIX
sockets. According to the code if the "-b address:port"
option is used and the port number is illegal or omitted then
all the "address:port" string assumed as a UNIX socket name.
That means that the UNIX socket should allways include a ":"
in its filename. My patch eliminate this limitation. After
applying it one should use "-b socket:" for UNIX sockets and
"-b address:port" or "-b port" for TCP/IP. And if the port
number is illegal, an error message is printed. If the "-b
socket:" format is used the ":" is not added to the UNIX
socket filename.

What do you think about following patch?

This patch changes an OS_CreateLocalIpcFd() function. The
same change of OS_FcgiConnect() should probably be done as
well. I didn't because the OS_FcgiConnect() isn't used
anywhere by php.
