Security update: 2.12.4, 2.11.12, 2.10.7 (CVE-2017-15288)
Security update: 2.12.4, 2.11.12, 2.10.7 (CVE-2017-15288) A privilege escalation vulnerability (CVE-2017-15288) has been identified in the Scala compilation daemon. We recommend upgrading to the latest versions of Scala (Scala 2.12.4, Scala 2.11.12 or Scala 2.10.7). The compile daemon is started explicitly by the fsc command, or implicitly by executing a Scala source file as a script (e.g scala My
負荷試験ツールgatlingで徐々に負荷をあげて一定に達したらキープ - Qiita
概要 gatlingという負荷試験ツールの結果が見栄え良いとのことで試してみた。 どんなものか ScalaなDSLでテストケースを記載するjmeter的なもの。QuickstartとAdvanced Tutorialを実施するとどういうものかわかるかと。 DSLの独特な所としてはUserとScenarioという概念があり、実際に人がブラウザを操作してる感覚+高級言語で表現できるは良いかと。 例えば「hoge.comの/hoge見た後/fugaを見る」というScenarioのUserを10分間に100User分負荷を発生、という感じで、ユーザがブラウザを操作する振る舞いをDSLにいい感じに表現できる。 実際にはwebアプリは複数のページ遷移で1アクションなこともあるので、このように書けると便利そうね、と。 導入 以下、linuxの場合。 jdk落としてきてインストール Gatling Pro
sbt Reference Manual — Def.taskDyn を用いて動的タスクを定義する
Def.taskDyn を用いて動的タスクを定義する 逐次タスクだけで十分じゃなければ、次のステップは動的タスクだ。純粋な型 A の値を返すことを期待する Def.task と違って、Def.taskDyn は sbt.Def.Initialize[sbt.Task[A]] という型のタスク・エンジンが残りの計算を継続するタスクを返す。 Compile / compile を実行した後で scalastyle-sbt-plugin の scalastyle in Compile タスクを実行するカスタムタスク、compilecheck を実装してみよう。 project/build.properties sbt.version=1.5.5 project/style.sbt addSbtPlugin("org.scalastyle" %% "scalastyle-sbt-plugin" %
Self-type
Self-types are a way to declare that a trait must be mixed into another trait, even though it doesn’t directly extend it. That makes the members of the dependency available without imports. A self-type is a way to narrow the type of this or another identifier that aliases this. The syntax looks like normal function syntax but means something entirely different. To use a self-type in a trait, write
Release Scala 2.12.4 · scala/scala
Our benchmarks show a further 5–10% reduction in compile times since 2.12.3. Improved Java 9 friendliness, with more to come! #6097 Fix runtime reflection of empty package members under Java 9 #6098 Adapt to change in Java 9 classloader hierarchy This release addresses (#6120) a privilege escalation vulnerability that was identified in the Scala compilation daemon CVE-2017-15288.

継続モナドを使ってWebアプリケーションのコントローラーを自由自在に組み立てる - Qiita
case class Cont[R, A](run: (A => R) => R) { def map[B](f: A => B): Cont[R, B] = Cont(k => run(a => k(f(a)))) def flatMap[B](f: A => Cont[R, B]): Cont[R, B] = Cont(k => run(a => f(a).run(k))) } ここで重要なのは Cont のコンストラクターに渡される run 関数です。 この run 関数を作り Cont のコンストラクターに渡すことで、継続モナドを作ることができます。 それで run 関数の型を見てみますと (A => R) => R とあります。 A => R という型の関数を受け取り、おそらく受け取った関数を実行し R という結果を返すという動作が期待できます。 ここで A を全体の中の途中の計
Release Scala 2.12.3 · scala/scala
Changes Compiler performance has improved significantly and is now automatically benchmarked after each change. A new optimizer setting -opt-inline-from limits the classes from which the inliner will copy code. scalac -opt-inline-from:help provides detailed help. The presentation compiler has improved support for implicit macros, which should improve the experience with libraries based on Shapeles

Support for BuildArch SPEC configuration · Issue #112 · sbt/sbt-native-packager
When running rpm:package-bin on OsX the rpmbuild tool seems to be slightly different than when running on a linux (Ubuntu/Centos). This might be due to some configuration error on my OsX rpmbuild of course... I'm trying to package a "noarch" rpm but on OsX it insists on building a "x86_64" rpm file even though the "noarch" flag is passed to rpmbuild. [debug] Executing rpmbuild with: rpmbuild -bb -
