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.
The idea to use "tracking" cache to save on typechecking operations is obsolete.
There is conflict of responsibilities with UpdatesRecorder,
which is to be solely relied upon for all things related to tracking changes.
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.
Fix rule basetag generation to coincide with templateName
Needed for PrincipalStore (occurrence cache) which uses
info about occurrence source rule template name.
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.
Avoid evaluating templates and producing rules on null
input and all required closure of this input, which effectively
constitutes the static collection of rules that are only
dependent on chosen aspect clique.
Avoid calling template's code if cached evaluation results are
not invalidated.
Keep information on required nodes (dependencies) together with
the list of produced rule ids.
Move invalidation logic inside UpdatesRecorder from elsewhere.
Drop type parameters.
Avoid recording dependencies for null input.
ProgramFactory: always process input, not only the first time
A query may be invoked without the input node, thus dispatching
macros by the specified concept. The concept must be taken into
account when calculating the "diff", so that the old (stale)
rules don't override the updated ones.
Avoid dereferencing DynamicReference from OriginIndex as it involves typechecking computation.
Aviod enqueing type nodes with TypesModelHandler during generation,
a workaround for "mature" references unable to be resolved
if target is in a transient (unpublished) model. (MPS-32709)
Ensure "local" typeof computation is used when queries a created with null root.
Specifically treat convertsTo of LogicalType to ClassifierType, support
convertsTo classifier type w/o specified classifier.
Fix typeOf LogicalItemValueExpression by to rely on logical's type.
Accept LogicalItem in LogicalItemValueExpression's logical slot to enable
replacement of it with an expression at generation time.
Drop node-ptr in node features, macro calls.
Drop node-ptr types in rule templates and recover closures,
fix BiConsumer params
Drop node-ptr// refs where appropriate.
Drop pointer operations from macro calls and term ctor's; add resolve to FunctionTypeLookup static table.
Drop node pointer operations from constraints, add require statements in SModel types macro table.
Absence of "principal" flag on "main" contstaint causes invalid
processing of added rules that are triggered by this constraint.
Introduce protective copying of arguments in IncrProgramSpecBuilder.
The builder implementation must not reuse the collection passed in as argument.
Also process expand macro input for rule hash,
so that changed query rules (like one in testlang) get into
RulesDiff and could be updated with Preamble processing.
Program Preamble consists of 2 parts: rules & Journal.
Preamble rules are no-input rules with rules for their required nodes.
Preamble journal is journal part with results of executing these rules.
Preamble is defined per-Query, because Journal differs for Queries.
Repository CacheHolder is used for storing them b/w sessions.
Rules are stored and retrievied with Memoizer.
Journal is stored as SessionToken in PreambleSet (map Query->SessionToken).
Add option to IncrementalSpec -- incrementality level (Preamble or Full).
Ensure the order of rules in the resulting plan follows the priorities
set forward by extends relationship b/w languages. So that even if
rule template tables are unrelated, they are still ordered according to
language extension graph.
Ensure the order of rule lists in the resulting plan is stable b/w invocations of
RulesPlanHandler.allPlans().
Ensure the order of aspects in AspectClique is stable b/w invocations
of buildClique().
Associate RuleTemplatesTable with Manifest, and Manifest with CoderulesAspect.
Tentatively rename RulesList (the runtime object) to RulesPlan,
RulesListTable to RulesPlanHandler.
Too many nodes get into tmpl application process, which is unnecessary.
Many of those nodes are required actually only for correctly tracking
changes to nodes with WatchingTypecheckingStrategy.
Now implicitly required only nodes which are mentioned inside
constraint arguments. In other cases user must require them explicitly.
Alter the way invalidated nodes are handled by UpdatesRecorder.
A set of "source" nodes is now maintained, which helps to
detect the appropriate input for a changed node.
Templates are applied only to "new" or "invalidated" nodes.
Rename TypeDependenciesNodeTracker to RelevantNodesMonitor and
have it the only implementation.
The "stub" implementation was never really used.
Simplify creation of and access to the monitor.
