[uClinux-dev] still haserl problems with boa on uCLinux

Mon Jun 9 10:16:37 EDT 2008

Hi Experts,

I'd like to do the configuration script with haserl.

I got haserl itself running perfectly in the uCLinux distribution. 

It parses the input script when same is used as an application (chmod 777 has; ./has) and outputs exactly what I think it should.

But when executing the file via the browser and boa I get:

"500 Server error".

This means boa does try to execute the file. (if e.g. executable is not set on the file I get " forbidden" instead).

If I do this and do

./has > ss

To move the output of haserl into a file and create another script file

sss:
#!/bin/msh
echo /home/httpd/cgi_bin/ss

Now when browsing to /cgi_bin/sss, I get the correct web page via boa, thus using a script as cgi-program with boa does work.

But when browsing to /cgi_bin/has, which should do exactly the same, I still get "500 Server error" .

Now I tried to enable the log and error scripts for boa in "menuconfig"

This does work: I do get decent entries in the log script and after killing the boa process I do see appropriate entries in the error script, too.

But when I access "has" via boa (with scripts enabled) the complete system hangs. I still do get "500 Server error" but afterwards everything is dead. (other than with boa logs disabled).

I attach the content of the haserl script file and the output of haserl at the end of the message.

When using the same versions of boa and haserl and a very similar script file (dropping the shell= specification) this runs perfectly nice.

Any idea what to do to debug this  ?

Thanks a lot
