- left only "required" -- the only kind of dependency that is relevant
- drop the old two-stage scheme of incremental processing
- implement a heuristic to detect if an update has caused any change,
and only propagate the update further the inverse requirements graph
in case there were real changes
- drop cached memo
- various code simplifications and refactorings
- interface Effect becomes a class AbstractEffect
- hasValue dropped
- getValue/allValueKeys have been made protected
- withValue(s) defines clear contract for using the values in effects
- cleanup the code, rename symbols for better readability
- drop dead code
- support for optionally showing empty template trace nodes
- display node path for source nodes
The deisgn decision to have only one instance of QueryTemplate
leads to the necessity to keep AspectClique separated for
every "typesystem". Whereas QueryTemplate are really perfectly
composable, and thus only one AspectClique is neeeded.
Also drop a rudimentary unused feature.
Refactor supervisor/feedback consumer to support feedback basis.
Track (in)validated rules tags in RulePlanHandler.
Both (in)- and validated rules cause associated feedback to be cleared.
Disable passing SessionToken in WatchingIncremental strategy;
this forces the correct journal recording but turns off incrementality.
Invalidated and introduced nodes are collected by UpdatesRecorder.
If either set is not empty, a walk of the input is triggered.
Also, drop invalidated flag in RulesPlanHandler.
Introduce invalidated flag to program producer to control whether to
only process invalidated nodes in incremental mode.
Update validated flag in RulesPlanHandler to reflect the finalized
state, after the plan has been built.
Refactor ProgramProducer/Factory to avoid enumerating the source
root in case no changes have been detected (in incremental mode).
Avoid relaunching program in case the producer did nothing.
A problem with collections language is that linkedlist type
gets generated into a Deque. There is a workaround for this,
which fails to work because of another problem in collections
language: linkedlist not being a direct subtype of LinkedList.
Probably a legacy code issue.
Enable rule index to be updated during rules application.
Make RuleProcessingSession depend on AspectClique.
Enable updating of rule/macro/query indices.
It's important that program that uses occurrences from cache
shouldn't include rules that could produce their duplicates.
So implementation of occurence cache includes 2 parts:
on reactor level & in ProrgramFactory.
When RuleBuilders are produced, cache is queried whether
there're already occurrences associated with the rule template
in question. If so -- then those RuleBuilders are not included
into the program (as well as all RuleBuilders required by it).
Get information on invalidated nodes from EvaluateStep & incr processing
instead of UpdatesRecorder, which has only partial info and can't handle
all cases.
