Provide implementation of invalidation logic that takes computed
name hashes into account. The implementation is spread amongst two
classes:
1. `IncrementalNameHashing` which implements a variant of
incremental compilation algorithm that computes modified
names and delegates to `MemberReferenceInvalidationStrategy`
when invalidating member reference dependencies
2. `MemberReferenceInvalidationStrategy` which implements the
core logic of dealing with dependencies introduced by member
reference. See documentation of that class for details.
The name hashing optimization is applied when invalidating source files
having both internal and external dependencies (in initial iteration),
check `invalidateByExternal` and `invalidateSource` methods for details.
As seen in implementation of `MemberReferenceInvalidationStrategy`
the name hashing optimization is not applied when implicit members
change.
NOTE: All functionality introduced in this commit is enabled only
when `IncOptions.nameHashing` flag is set to true.
The `source-dependencies/transitive-memberRef` test has been changed
to test name hashing variant of incremental compilation. The change
to invalidated files reflects the difference between the old and the
new algorithm.
Also, there a few new tests added that cover issues previously found
while testing name hashing algorithm and are fixed in this commit.
Each paragraph describes a single test.
Add a test case which shows that detect properly changes to type aliases
in the name hashing algorithm. See gkossakowski/sbt#6 for details.
Add test covering bug with use of symbolic names (issue
gkossakowski/sbt#5).
Add a test which covers the case where we refer to a name that is
declared in the same file. See issue gkossakowski/sbt#3 for details.
