problem in executing CGI Error

hi,

I am getting "500 Internal server Error" on the newly build CGIs.

Can I see the root cause of these erros .?

Where can I see the CGI logs in Interwoven?

thanks ,

CGI script errors are loged in "error_log" file of the TeamSite web deamon.

Check that the CGIs compile

iwperl -c foo.cgi

Also, I run it from the shell to see the output. Much easier than parsing log files.

I'd also suggest adding the following to your CGI code:

use CGI::Carp qw(fatalsToBrowser);

At least during development - this will display the error information in the browser window so you don't have to go searching for / through the log files.

If you are on unix, one very common problem which would cause that error - check that you have execute permission on the script.

chmod +x foo.cgi

Secondly - Are you printing script header "Content-type: text/html\n\n"; before printing anything?

Another Unix gotcha occurs if you've been developing your script on a windows PC. On unix:

vi myscriptname.ipl

You may see loads of ^M characters at the end of each line. Type ":q" to quit vi and then both of the following:

dos2unix myscriptname.ipl myscriptname.ipl
chmod +x myscriptname.ipl

will remove them for you.

omygod... in order to fix ^M in vi one has to type just this:


:1,$s/^M//g

here ^M are entered as Ctrl-v Ctrl-M

Indeed, search/replace will do the job much quicker ;-)

Or:

:%s/^M//g

'%' addresses the entire file - regardless of your current position - it's essentially the same as '1,$' but two characters shorter ;-)

FYI, dostounix not well written. If you run it on a binary file, it will screw up that file.

From my experince, if there is 1 file with ^M then there are multiple. So I like to run a command on all files in a directory. Hense I wrote a perl script to so that.

Adam.. I am impressed Smiley Happy

surely, you are taking part in obfuscated perl competitions Smiley Happy
