PHP proc_open problems on windows

Question

I have the following code

$env=array('PATH'=>'C:\Program Files\MySQL\MySQL Server 5.1\bin',
           'PATHEXT' => '.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC');
$cmd='mysql "--port=3306" "--host=127.0.0.1" "--user=root" "--password=xxxx" <"C:\Projects/script.sql" 2>&1';
print $cmd;
$proc = proc_open($cmd, $descriptorspec, $pipes, NULL, $env) or die("Cannot run $cmd");

while ($line=fgets($pipes[1])) print $line;

print "\n\nCompleted\n";

And the output I get is

ERROR 2004 (HY000): Can't create TCP/IP socket (10106)

Why is the port option being ignored? The command works perfectly well on the command line.

Answer 1

The error seen

ERROR 2004 (HY000): Can't create TCP/IP socket (10106)

is raised by mysql, so the mysql process actually started.

This error corresponds to CR_IPSOCK_ERROR, and it prints the underlying root cause of the problem: 10106.

A quick search gives:

http://msdn.microsoft.com/en-us/library/windows/desktop/ms740668%28v=vs.85%29.aspx

and in particular:

WSAEPROVIDERFAILEDINIT
10106

Service provider failed to initialize.
The requested service provider could not be loaded or initialized. This error is returned if either a service provider's DLL could not be loaded (LoadLibrary failed) or the provider's WSPStartup or NSPStartup function failed.

I don't think this has anything to do with the port number being "ignored", and even less firewall issues.

It appears as if the environment created by proc_open is good enough to start the mysql process, but yet not complete enough so that calls to LoadLibrary from within that process, to load the networking code namely, are failing.

The same command works from the command line, most likely because the environment in the command line contains much more.
