Hi,
How do others debug CGI web apps written in Object Pascal? Yesterday I
spent a significant amount of time debugging a few difficult problems. It
took much longer than expected. Even though the CGI apps are written in
Object Pascal I couldn't use GDB to step through the code (if one can,
please let me know), so i had to solely rely on logfile output.
Well, I'm currently very busy with CGI, and I use dbugintf and the
debug server app from Lazarus. Works like a charm for me.
Is there a better way of debugging CGI applications? Note I am not using
any web-type framework. I'm using very limited features of PWU - most
output is simply by writeln('...') statements, but our CGI apps do use
Cookies, OOP, Database Access etc..
I have Kylix 3 Enterprise at my disposal as well. Could that maybe be used
to help debug CGI apps? Though this might be more work than I would wish
for, because I doubt our code is Kylix compatible.
Is it at all possible to step through CGI apps with GDB?
Not directly.
You can use the embedded server created by Joost van der sluis, (see his
webdesign package) or use a fastcgi app: as soon as it is started, connect
gdb to it, with the -p option.
Michael.
