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.
Instead of copying cached data just re-plant the fields to the new cache.
The new types-model to contain only the newly reported types. Types reported on earlier invocations are retained
in previously created models.
Refactor whe way TypecheckingResultsCache is updated:
all mutatiting methods extracted to Update subclass, which is
only available to the updater.
Make TypecheckingState a regular container for (unit) caches.
Make TypecheckingService responsible for managing caches.
Extract TypeModuleOwner and TypeModelHandler classes.
Get rid of QueryResultsCache, merge into TypecheckingResultsCache.
TypeModuleOwner to manage "repository" cache.
When running typechecking with trace=on too much memory is taken up
by the traces, the new option enables to see the evaluation results
without collecting the traces.
Optimization: Use repo/unit caches for storing various data in Caching strategy
Fix: introduce workaround for nodes coming from generator's transient model --
avoid clearing cache for non-resolvable origin nodes.
Fix: incrProgSpec not passed correctly downstream, incremental mode working only with trace on.
Refactoring: make TypesCollector a (private) singleton. TBD.
Rename SessionData -> CachedData.
Make use of MutableLogical's feature to track usages count.
A logical with 1 or less usages can't be contained in
another term, so it's safe to skip unification in this case.
During template application memo can be used to store results
of a computation in the session. The memo will be automatically
cleared on an event that invalidates the caches.
IncrProgramSpec influencing program eval is built from two sources:
internal analysis results & typechecking options.
Providing spec builder instead of spec allows to combine these
sources later at program pipeline creation in TypecheckingService.
Commit accomodates to addition of IncrementalSpec.Enabled.Unsafe
Commit also simplifies ProgramAnalysis -related classes.
Renames BasicProgramAnalysis to PrincipalsAnalysis.
The flag "recursive" is passed down to ProgramFactory to control whether
the input nodes are to be walked recursively.
This flag is set to false when calculating a node's type in isolation.
TypecheckingCache maintains two maps of root-to-cache: tracking and non-tracking.
Tracking cache is used in "watching" mode, caching mode doesn't require tracking.
Always merge the results of typechecking, avoid replacing the cached data.
Reimplement calcTypeLocally() to rely on cache for storing the resulting type.
Simplify cache API.
Fix TypecheckingTestHelper.
TypecheckingService has become too overloaded with responsibilities, and
so Strategy class is introduced to extract strategies to.
Cache holder can also be non-tracking, which comes in handy when
implementing purely caching typechecking, not anticipating any change.
TypecheckingService and provider component are explicitly dependent
on SRepository.
The repository instance comes from the first opened project, which
is a dirty hack and is temporary until Typechecking Facade API
is fixed to provide appropriate instance.
Operations such as 'error' and 'warning' are available on input
node in templates and serve to report issues found during
template application, in contrast with those found during evaluation.
