Merge lp:~wyuka/zeitgeist-datasources/purple into lp:zeitgeist-datasources/0.8

[Tirtha Chatterjee]

Added a datasource for libpurple

Added a datasource for libpurple, the library used by Pidgin and Adium.

[Manish Sinha (मनीष सिन्हा) (manishsinha)]

In purple/zeitgeist_dataprovider.c

> Zeitgeist dataprovider for XChat is free software;

Should be purple instead of XChat

> Zeitgeist dataprovider for XChat is distributed in the hope that

Should be again purple.

This would take some time as we need to make sure that the ontology are proper and does correspond to telepathy's data-source ontology perfectly to avoid any issues

[Michal Hruby (mhr3)]

First of all, I really don't think logging every sent and received url is a good idea, I'd get rid of all of that. (anyway if the user clicks on the url, it'll be logged by the browser dataproviders). @manish: objections?

Second, signed-on/off are not too interesting either imo, at very least they shouldn't be USER_ACTIVITY.

Let's get to something more specific (line numbers as seen in LP's diff):
681 727: libzg has method (zeitgeist_interpretation_for_mimetype) which turns mime-type into Interpretation, use that please.
...,686,...: storage parameter for ZeitgeistSubject is often wrong, local files are never "net".

Other than that there are a couple of leaks:
619: account_uri
671, 717: file
672, 718: parent

I'm no purple plugin expert, but I'd say you should disconnect the signals in the unload method.

[Michal Hruby (mhr3)]

Oh and all instances g_file_get_uri leak as well.

[Manish Sinha (मनीष सिन्हा) (manishsinha)]

@Michal

I see there is anyway not harm in logging all the sent and received URLs. The use-case can be "I sent you the URL of _some_random_person_ facebook profile, didn't you see it". Logging the URL might help in this case
