Julius Volz fc97e688c6 Improve printing of rules and expressions. 2013-06-11 11:39:31 +02:00
Julius Volz 74cb676537 Implement Stringer interface for rules and all their children. 2013-06-07 15:54:32 +02:00
Julius Volz 51689d965d Add debug timers to instant and range queries. 
This adds timers around several query-relevant code blocks. For now, the
query timer stats are only logged for queries initiated through the UI.
In other cases (rule evaluations), the stats are simply thrown away.

My hope is that this helps us understand where queries spend time,
especially in cases where they sometimes hang for unusual amounts of
time.

Julius Volz 0877680761 Implement a COUNT ... BY aggregation operator. 
This also removes the now obsolete scalar count() function and corrects the
expressions test naming (broken in
2202cd71c9 (L6R59))
so that the expression tests will actually run.

Julius Volz 2c8595f96e First graphing support. 2013-01-22 02:27:26 +01:00
Matt T. Proud efe61c18fa Refactor target scheduling to separate facility. 
``Target`` will be refactored down the road to support various
nuanced endpoint types.  Thusly incorporating the scheduling
behavior within it will be problematic.  To that end, the scheduling
behavior has been moved into a separate assistance type to improve
conciseness and testability.

``make format`` was also run.
