Goanna and webserver

patrickr — Fri, 20 Apr 2007 02:16:10 -0700

Goanna is used for the xmlrpc interface using fastcgi and apache. The website itself is based on Drupal and uses php. I also did some testing with lighttpd which also seems to work fine with goanna fastcgi and which is a lot faster and scales better http://origo.ethz.ch/index.php/Performance

First thoughts

Very interesting. Are you using Goanna as part of the software? There is no tag for it. What are you using to provide HTTPS communications?

External access will be available soon

There will be access to the API very soon. The API is split in an internal and external part, the internal part is very small and almost everything is also available externally. For external applications, login will be done with a per user key to prevent brute force password hacking attempts.

Another student is already working on creating plugins for EiffelStudio, VisualStudio and Eclipse

Client tools

I've already got my project page up!

I forgot to ask till, and maybe you know. is the XMLRPC accessible to external clients? Just thinking about the client tools domain. Actually it would nice to have a Eiffel framework API we could use for the purpose of developing tools (We developers only want more, more, more!)

Ok. I would have thought

Ok. I would have thought that when detach returned, after the call to fork, that execution would have continued within the if-then, and then fallen through bypassing the call to execute. I was confused, I guess, so I'll have to study it some more.

No. Detach, forks and then

No. Detach, forks and then calls execute in the new process.

Correction?

Neitsdelf — Fri, 13 Apr 2007 07:13:56 -0700

Shouldn't the call to "execute" be outside of the if-then conditional?

Eiffel and Unix

I personally would be interested to know how to setup signal handlers in Eiffel.

That's basically not that

patrickr — Mon, 02 Apr 2007 15:33:05 -0700

That's basically not that hard. In general on Unix/Linux, the way it is done is to let the process fork itself and then end the parent process. As soon as the parent process exits, the child process is automatically inherited by the init process and can therefore be considered a daemon. In Eiffel probably the easiest way to do it, is to use eposix. Another aspect that should also be done is to implement some signal handlers (e.g. for the TERM signal, to be able to shut down a daemon), I also did this using eposix. If there's interest I can write a quick article about it.

How do you turn your processes into daemons?

Would be interesting to know.
