1. All parents of public/exported classes/modules/packages are tracked as
'publicInherited' dependencies. These are dealiased and normalized so
that the dependency is on the actual underlying template and not the
source enclosing the alias.
2. All CompilationUnit.depends dependencies are direct dependencies. These
include inherited dependencies.
3. When invalidating changed internal sources,
a. Invalidate all inherited dependencies, transitively and include the
originally modified sources,
b. Invalidate all direct dependencies of these sources,
c. Exclude any sources that were compiled in the previous step unless they
depend on a newly invalidated source.
4. Invalidate changed external sources in the same way as #3 but remove the
external sources from the final set.
Only public inheritance dependencies need to be considered because a template
that is not accessible outside its source file and that inherits from another
file can be handled as a normal, direct dependency. Because the template
isn't public, changes to its API will not propagate outside of the source
file.
Several existing tests cover the correctness, especially:
1. transitive-a covers direct, transitive dependencies with inferred return
types
2. transitive-b covers inherited, transitive dependencies with inferred return
types
There are two new tests, one that tests that public inherited dependencies are
tracked and one that verifies the basic invalidation progression.
More tests are needed to verify the improvements that this algorithm brings:
1. Inheritance-related dependencies are processed in one step to avoid the
otherwise unavoidable several steps.
2. Only immediate direct dependencies are ever processed, which should in many
typical cases avoid large invalidation sets.
In summary this commit:
* drops type normalization in api phase but keeps dealiasing
* fixes#736 and marks corresponding test as passing
I discussed type normalization with @adriaanm and according to him
sbt shouldn't call that method. The purpose of this method to
convert to a form that subtyping algorithm expects. Sbt doesn't need
to call it and it's fairly expensive in some cases.
Dropping type normalization also fixes#726 by not running into
stale cache in Scala compiler problem described in SI-7361.
according to this
http://www.scala-sbt.org/sbt-pgp/usage.html#publishing_artifacts
"The PGP plugin NO LONGER wires into the default publish and publish-local tasks of sbt. If you want to published signed artifacts, you must use the new publish-signed and publish-local-signed tasks."
This bit me when i tried to do this today, should update the docs to refer to the proper command `publish-signed` so the next guy who tries this doesn't get bitten.
-Changed usages and implementations of interfaces in org.scalatools.testing._ to use/implement interfaces/classes in sbt.testing._ instead.
-Added sbt.testing to interfaceFilter in TestFramework.createTestLoader method to enable loading of classes in sbt.testing package.
-Added FrameworkWrapper.java to wrap old framework implementations.
-Added code in ForkMain.java to serialize Selectors.
