#40758 [NEW]: Test fcgi_is_fastcgi() is wrong on windows

[jostb2345 at yahoo dot com]

From: jostb2345 at yahoo dot com
Operating system: Windows (all versions)
PHP version: 5.2.1
PHP Bug Type: Reproducible crash
Bug description: Test fcgi_is_fastcgi() is wrong on windows

Description:
------------
On windows, php 5.2.0 and above the following code (written in
pseudo-code) doesn't work anymore:

socket = socket(AF_INET, ...);
bind(socket, ...);
listen(socket, ...);
outputHandle=GetStdHandle(...);
inputHandle=socket;
CreateProcess(...,"php-cgi.exe", ..., IOHandles);

The problem is that "is_fastcgi" is only set if the OutputHandle and
ErrorHandle are invalid. If both are invalid, InputHandle is assumed to be
a named pipe.

The Unix version still uses the old (correct) code.

To correct this problem either the old FCGI_isfcgi() should be used or the
test must be dublicated. See procedures:

int fcgi_init(void);
int fcgi_is_fastcgi(void);


Regards,
Jost Boekemeier




Reproduce code:
---------------
See above. If necessary I can provide a test program.

I don't see any difference with old code. See OS_IsFcgi() and

PHP.

Because I thought you need to distinguish sockets from named pipes.
I have attached code which crashes php since 5.2.0.

yes. PHP expects pipe but not a socket.

In C you may even try to pass window HANDLE :)

May be older PHP versions were able to support sockets on win32, but I
have never seen any FastCGI plugin implmentation that passes sockets.
Also I don't see any sockets advantages (only disadvantages).

I don't think named pipes work on all operating systems. Furthermore
Java supports only TCP socket communication (well, it is possible to
access Windows and Unix named pipes from Java. But one has to implement
it twice. RandomAccessFile on Windows, a pair of normal Files on Unix).


To be practical -- and for backward compatibility -- we need a working
TCP socket implementation on both operating systems. tcp sockets worked
in PHP versions < 5.2.0 and I don't see a good reason to drop this.

Description:
------------
On windows, php 5.2.0 and above the following code (written in
pseudo-code) doesn't work anymore:

socket = socket(AF_INET, ...);
bind(socket, ...);
listen(socket, ...);
outputHandle=GetStdHandle(...);
inputHandle=socket;
CreateProcess(...,"php-cgi.exe", ..., IOHandles);

The problem is that "is_fastcgi" is only set if the OutputHandle and
ErrorHandle are invalid. If both are invalid, InputHandle is assumed to
be a named pipe.

The Unix version still uses the old (correct) code.

To correct this problem either the old FCGI_isfcgi() should be used or
the test must be dublicated. See procedures:

int fcgi_init(void);
int fcgi_is_fastcgi(void);

Reproduce code:

See above. If necessary I can provide a test program.
