Description

Hi,
I use lighttpd with mod_fastcgi. The example code is written in C. It uses libpq-fe.
I put a String into the database (dump attached) which cause a weird behaviour. I read everything out of "message.stdlib_comments" and print it out. Lets say i would like to print:
asdf1
asdf2
asdf3
lighttpd only prints
f1
asdf2
asdf3
Why? i doesn't know. For me, there is nothing special. It seams he starts printing after an special char. If you excecute the code without lighttpd (only ./whatever), it prints the correct stuff.
Tested under FreeBSD 8.0 and Gentoo with lighttpd version 1.4.26.
Compile the attached code with:
gcc -lfcgi -lpq index.c -o index
postgresql needs an role called pgsql. No password.
On my system, the binary is called index.c. It's not a bug in *.conf

"high" is reserved for critical stuff, this doesn´t sound like it.

Try to debug your fcgi, e.g. attach strace to it.

Ok here is the code without postgres. Maybe it's easier to test it. Only fcgi loop and printf. Nothing else.
The same output works fine with php.
I'm not familiar with bugtrackers. Sry for wrong priority.

Try \r\n\r\n instead of \n\n

Sure i can delete every \r but thats not the right way. Imho it is a bug in fcgi or lighttpd.

he said use \r\n instead of \n. so this

printf("Content-type: text/html\n\n");

becomes

printf("Content-type: text/html\r\n\r\n");

No, you should not remove \r but ADD. You use \n\n instead of \r\n\r\n. Did you look at the fastcgi examples on fastcgi.com?
http://www.fastcgi.com/devkit/examples/echo.c

Your stuff does not output valid HTTP responses.
