As noted in the original bug, simply querying all the event ids in a time range 
and then handing it to delete_events causes the SQL error described: Too many 
variables

Finding an ID simply searches for an ID and returns -1 if one is not found.

Getting an ID is defined as returning a valid ID number for the given string 
one way or another.

Adding a default argument to a vala method that is public breaks source and 
binary compatability with users of the generated C code.

[Zeitgeist] [Bug 953041] [NEW] Extraneous actors are inserted into sqlite database during read-only operations

2012-03-12 Thread Trever Fischer 
Public bug reported:

Example code:

import time, os
from gi.repository import GObject
from zeitgeist.client import ZeitgeistClient
from zeitgeist.datamodel import Event, Subject, Interpretation
zg = ZeitgeistClient()

event_template = Event()
event_template.actor = foo

mainloop = GObject.MainLoop()

def callback(events):
print len(events)
mainloop.quit()

zg.find_events_for_templates([event_template], callback, num_events=100, 
result_type=0)
mainloop.run()

Searching the actors table in sqlite shows a foo actor after
execution.

[Zeitgeist] libqzeitgeist is now in KDE git

2011-05-21 Thread Trever Fischer 
Howdy, all.

As I discussed with Seif earlier this week, libqzeitgeist has finished its move 
to KDE git. The new homepage for the project is 
https://projects.kde.org/projects/kdesupport/libqzeitgeist

This move should inspire more KDE developers to begin to use Zeitgeist in 
their applications, now that the Qt library is part of KDE's development 
infrastructure including CIA, bugs.kde.org, Reviewboard, EBN, and others.
