Re: [Tracker] [tracker-list] network support

I have done dbus proxy that exposing some bus name (e.g.
org.example.Proxy) and passess all method calls to another bus
connection (e.g. org.freedesktop.Notifications). Next step is to add
network layer. I am thinking of using HTTP as transport and FastCGI.

Attached is a response-reply from a reply that Dmitry sent me on my
private E-mail address. I think it's interesting for the list, so I'm
forwarding it.

What do you think about this idea?


Why don't you just make an apache module that converts the results that
you get from DBus to RDFXML? http://www.w3.org/TR/REC-rdf-syntax/

You might have to do a bit of setuid()-ing to get the right session bus
from DBus. Maybe this: http://httpd.apache.org/docs/2.1/suexec.html ?

http://httpd.apache.org/docs/2.1/mod/mod_suexec.html#suexecusergroup

If you do it as an apache module then you'll get all the security
features of Apache for free. Like https, and authentication.

http://httpd.apache.org/docs/2.2/howto/auth.html

Surely you don't want your custom server to implement all that stuff if
Apache has done it all already?

Cheers

Philip

Thank you for advices.
I will report how development going in this thread.

Thank you anyway! Now I am experementing with tracker dbus interface.


There exist a few lightweight webserver softwares. And some of them
allow you to use apache modules too. Perhaps check those out?

Ideally your code can be easily configured to be an apache module, or a
module for such a lightweight webserver.

Then we can let the code function as either of the two. Without
reinventing the same code for both situations.

Remember that although Apache might be heave in your eyes, that a lot of
systems already come with an Apache preinstalled. And then your service
can't allocate port 80 or 443, of course.

But if we integrate the solution with a few existing webserver
softwares, it might work out just fine. Maybe with a fallback that
listens on a port all by itself.

Note that we wont enable listening on any port like this unless the
service has SSL and authentication.

You can probably understand that exposing all of a user's metadata on
the bloody Internet isn't the brightest idea security and privacy
wise? :)


Cheers,

Philip
