We've had a lot of failed builds recently and it seems to coincide with when we updated from Scala.js 0.6.8 to 0.6.11. This is an experiment to see if reverting that change stabilizes the build. --- project/plugins.sbt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/project/plugins.sbt b/project/plugins.sbt index 99b8264fd7..01c472928a 100644 --- a/project/plugins.sbt +++ b/project/plugins.sbt @@ -9,6 +9,6 @@ addSbtPlugin("pl.project13.scala" % "sbt-jmh" % "0.2.3") addSbtPlugin("org.scalastyle" %% "scalastyle-sbt-plugin" % "0.8.0") addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.2.0") addSbtPlugin("com.typesafe.sbt" % "sbt-git" % "0.8.4") -addSbtPlugin("org.scala-js" % "sbt-scalajs" % "0.6.11") +addSbtPlugin("org.scala-js" % "sbt-scalajs" % "0.6.8") addSbtPlugin("com.github.tkawachi" % "sbt-doctest" % "0.3.5") addSbtPlugin("org.xerial.sbt" % "sbt-sonatype" % "1.1") From 72c6c24a7bb58c365327a2121386dea6957ffacc Mon Sep 17 00:00:00 2001 From: Cody Allen Date: Sat, 30 Jul 2016 11:14:59 -0400 Subject: [PATCH 3/4] Don't run stack-safety tests for JS This is a shot in the dark attempting to fix #1242. The idea is that we can mark certain tests as slow and not run them when running JS tests. Currently I've done this for all of the stack-safety tests that I can find. I don't really like this solution, but currently almost every PR is resulting in a failed build, which is really problematic. One thing that we could do is get rid of the `Platform.isJs` branch of the `slowTest` implementation locally just before a release to make sure that these tests all pass on JS. I think we only really run into these issues on Travis CI. --- .../scala/cats/free/FreeApplicativeTests.scala | 2 +- free/src/test/scala/cats/free/FreeTests.scala | 6 +++--- .../src/test/scala/cats/tests/CatsSuite.scala | 13 +++++++++++++ .../test/scala/cats/tests/FoldableTests.scala | 2 +- .../cats/tests/MonadRecInstancesTests.scala | 18 +++++++++--------- .../test/scala/cats/tests/ReducibleTests.scala | 4 ++-- .../test/scala/cats/tests/StateTTests.scala | 2 +- 7 files changed, 30 insertions(+), 17 deletions(-) diff --git a/free/src/test/scala/cats/free/FreeApplicativeTests.scala b/free/src/test/scala/cats/free/FreeApplicativeTests.scala index 2c9039ab0c..6903a509de 100644 --- a/free/src/test/scala/cats/free/FreeApplicativeTests.scala +++ b/free/src/test/scala/cats/free/FreeApplicativeTests.scala @@ -28,7 +28,7 @@ class FreeApplicativeTests extends CatsSuite { checkAll("FreeApplicative[Option, ?]", ApplicativeTests[FreeApplicative[Option, ?]].applicative[Int, Int, Int]) checkAll("Applicative[FreeApplicative[Option, ?]]", SerializableTests.serializable(Applicative[FreeApplicative[Option, ?]])) -
