When scalaVersion is no longer effective an eviction warning will display.
Scala version was updated by one of library dependencies:
* org.scala-lang:scala-library:2.10.2 -> 2.10.3
When there're suspected incompatibility in directly depended Java libraries,
eviction warnings will display.
There may be incompatibilities among your library dependencies.
Here are some of the libraries that were evicted:
* commons-io:commons-io:1.4 -> 2.4
When there's suspected incompatiblity in directly depended Scala libraries,
eviction warnings will display.
There may be incompatibilities among your library dependencies.
Here are some of the libraries that were evicted:
* com.typesafe.akka:akka-actor_2.10:2.1.4 -> 2.3.4
This also adds 'evicted' task, which displays more detailed eviction warnings.
The scripted newer command was effectively a noop, it always passed
because it returned false instead of throwing an exception when it
failed.
Implemented specs for most of the scripted file commands as well.
Add scala 2.11 test/build verification.
* Add 2.11 build configuratoin to travis ci
* Create command which runs `safe` unit tests
* Create command to test the scala 2.11 build
* Update scalacheck to 1.11.4
* Update specs2 to 2.3.11
* Fix various 2.11/deprecation removals
and other changes.
Fix eval test failure in scala 2.11 with XML not existing.
The name hashing seems to be stable enough for sbt to use it by default
now. It also greatly improves incremental compilation experience for
people working on sbt sources.
* Modify scripted task parser to allow "pagination" of globs
e.g. "*1of3" will create three pages and run page 1.
* Modify travis definition to fragment long-running test groups
into pages so we stay under the 50 minute limit.
This reverts commit 36ec103274.
This 2.11.0 dependency was causing issues with older sbt launchers
attempting to use the 2.11.0 scala release for sbt's classloader,
leading to binary incompatibility issues.
The ff0fd6eec6 introduced some exclusions
that were necessary for getting sbt to resolve dependencies properly
against Scala 2.11.0-M7.
Scala 2.11.0-M8 fixed its dependency structure so we can get rid of those
exclusions now.
Still TODO for auto-plugins/logic:
* property-based tests for logic system
* user documentation
* (optional) 'about plugins' or similar to show more information about the auto-plugins for a project
* (deferred) allow AutoPlugin to inject Commands directly?
* (deferred) provide AutoPlugin functionality to arbitrary scopes instead of just at the Project level?
Tracking of used names is a component needed by the name hashing
algorithm. The extraction and storage of used names is active only when
`AnalysisCallback.nameHashing` flag is enabled and it's disabled by
default.
This change constists of two parts:
1. Modification of Relations to include a new `names` relation
that allows us to track used names in Scala source files
2. Implementation of logic that extracts used names from Scala
compilation units (that correspond to Scala source files)
The first part is straightforward: add standard set of methods in
Relations (along with their implementation) and update the logic which
serializes and deserializes Relations.
The second part is implemented as tree walk that collects all symbols
associated with trees. For each symbol we extract a simple, decoded name
and add it to a set of extracted names. Check documentation of
`ExtractUsedNames` for discussion of implementation details.
The `ExtractUsedNames` comes with unit tests grouped in
`ExtractUsedNamesSpecification`. Check that class for details.
Given the fact that we fork while running tests in `compiler-interface`
subproject and tests are ran in parallel which involves allocating
multiple Scala compiler instances we had to bump the default memory limit.
This commit contains fixes for gkossakowski/sbt#3, gkossakowski/sbt#5 and
gkossakowski/sbt#6 issues.
Fix the problem with unstable names synthesized for existential
types (declared with underscore syntax) by renaming type variables
to a scheme that is guaranteed to be stable no matter where given
the existential type appears.
The sheme we use are De Bruijn-like indices that capture both position
of type variable declarion within single existential type and nesting
level of nested existential type. This way we properly support nested
existential types by avoiding name clashes.
In general, we can perform renamings like that because type variables
declared in existential types are scoped to those types so the renaming
operation is local.
There's a specs2 unit test covering instability of existential types.
The test is included in compiler-interface project and the build
definition has been modified to enable building and executing tests
in compiler-interface project. Some dependencies has been modified:
* compiler-interface project depends on api project for testing
(test makes us of SameAPI)
* dependency on junit has been introduced because it's needed
for `@RunWith` annotation which declares that specs2 unit
test should be ran with JUnitRunner
SameAPI has been modified to expose a method that allows us to
compare two definitions.
This commit also adds `ScalaCompilerForUnitTesting` class that allows
to compile a piece of Scala code and inspect information recorded
callbacks defined in `AnalysisCallback` interface. That class uses
existing ConsoleLogger for logging. I considered doing the same for
ConsoleReporter. There's LoggingReporter defined which would fit our
usecase but it's defined in compile subproject that compiler-interface
doesn't depend on so we roll our own.
ScalaCompilerForUnit testing uses TestCallback from compiler-interface
subproject for recording information passed to callbacks. In order
to be able to access TestCallback from compiler-interface
subproject I had to tweak dependencies between interface and
compiler-interface so test classes from the former are visible in the
latter. I also modified the TestCallback itself to accumulate apis in
a HashMap instead of a buffer of tuples for easier lookup.
An integration test has been added which tests scenario
mentioned in #823.
This commit fixes#823.
