spawn-fcgi.exe does not appear to work in Windows

Added by keathmilligan about 8 years ago

On Ubuntu, I have a simple FastCGI "Hello, world" app that I can spawn with:

spawn-fcgi -f ./fcgitest -a "" -p 2222 -n

and it works great. But on Windows (both under XP and Vista), spawn-fcgi does not work. I've tried both the WLMP version of lighttpd and the Cygwin version and I get the same results.

If I run:

spawn-fcgi -f ./fcgitest.exe -a "" -p 2222 -n

It just runs and exits with no message. If I omit the "-n", it will say "child exited with: 0". I've tried playing around with various ways of specifying the arguments and sometimes it will say it spawned a child successfully, but the process is not actually running.

I can run the fcgitest program by itself with no error and I've also verified that spawn-fcgi is finding and running it, but it is exiting immediately because FCGI_Accept is returning "-1". I don't know if it is meaningful or not, but after FCGI_Accept fails, errno is 34 "Result too large".

FCGI_Accept is obviously in your application and there's nothing spawn-fcgi can do about this. Sorry.

Turns out the problem is that the WLMP version of Lighty uses Cygwin's file-descriptor handling and so anything spawned by its spawn-fcgi needs to be linked against Cygwin as well. If I simply relink my test app against the Cygwin version of libfcgi instead of the mingw version, it works. Since I don't my app to ultimately depend on Cygwin, I had to write a Win32-native version of spawn-fcgi.

I attached the source in case anyone else runs into the same issue. You can compile it with mingw (link with wsock32). It is mostly compatible with the original spawn-fcgi, but does not support chroot or setting uid/gid.

keathmilligan I got trouble compiling your code with mingw =(
Could you please throw me a hint or a compiled binary of your spawn-fcgi?

(link with wsock32)
I use CODEBLOCKS program for compile spawn fcgi and use LIB wsock32


si entiendes español; mira yo uso CODEBLOCKS para Compilar con minGW y para hacer correr la compilacion de Spawn-FCGI tienes que hacer un LINK a WSOCK32 que en CODEBLOCkS lo incluye como


en la ruta completa
C:\Program Files\CodeBlocks\MinGW\lib\libwsock32.a

yo use CODEBLOCKS minGW 8.02
