From 50eed6d62e7b2540c8847fcd418bdea8e59e07c9 Mon Sep 17 00:00:00 2001 From: Ethan Atkins Date: Thu, 30 Jul 2020 19:53:45 -0700 Subject: [PATCH 1/2] Disable pending dependency management tests Pending tests really slow down scripted runs because they tend often cause sbt to exit which means the next test has to reload the whole build instead of just reloading. Unfortunately cold loading is still pretty slow so this is significant overhead. Before disabling these, the dependency-management suite took 335 seconds on my computer. After, it dropped to 280 seconds. --- .../dependency-management/configurations/{pending => disabled} | 0 .../dependency-management/dynamic-revision/{pending => disabled} | 0 .../dependency-management/gh-1484-npe/{pending => disabled} | 0 .../dependency-management/module-confs/{pending => disabled} | 0 sbt/src/sbt-test/dependency-management/t468/{pending => disabled} | 0 5 files changed, 0 insertions(+), 0 deletions(-) rename sbt/src/sbt-test/dependency-management/configurations/{pending => disabled} (100%) rename sbt/src/sbt-test/dependency-management/dynamic-revision/{pending => disabled} (100%) rename sbt/src/sbt-test/dependency-management/gh-1484-npe/{pending => disabled} (100%) rename sbt/src/sbt-test/dependency-management/module-confs/{pending => disabled} (100%) rename sbt/src/sbt-test/dependency-management/t468/{pending => disabled} (100%) diff --git a/sbt/src/sbt-test/dependency-management/configurations/pending b/sbt/src/sbt-test/dependency-management/configurations/disabled similarity index 100% rename from sbt/src/sbt-test/dependency-management/configurations/pending rename to sbt/src/sbt-test/dependency-management/configurations/disabled diff --git a/sbt/src/sbt-test/dependency-management/dynamic-revision/pending b/sbt/src/sbt-test/dependency-management/dynamic-revision/disabled similarity index 100% rename from sbt/src/sbt-test/dependency-management/dynamic-revision/pending rename to sbt/src/sbt-test/dependency-management/dynamic-revision/disabled diff --git a/sbt/src/sbt-test/dependency-management/gh-1484-npe/pending b/sbt/src/sbt-test/dependency-management/gh-1484-npe/disabled similarity index 100% rename from sbt/src/sbt-test/dependency-management/gh-1484-npe/pending rename to sbt/src/sbt-test/dependency-management/gh-1484-npe/disabled diff --git a/sbt/src/sbt-test/dependency-management/module-confs/pending b/sbt/src/sbt-test/dependency-management/module-confs/disabled similarity index 100% rename from sbt/src/sbt-test/dependency-management/module-confs/pending rename to sbt/src/sbt-test/dependency-management/module-confs/disabled diff --git a/sbt/src/sbt-test/dependency-management/t468/pending b/sbt/src/sbt-test/dependency-management/t468/disabled similarity index 100% rename from sbt/src/sbt-test/dependency-management/t468/pending rename to sbt/src/sbt-test/dependency-management/t468/disabled From 1d08116a2e08f56ebe5238dd57b7c8621708999d Mon Sep 17 00:00:00 2001 From: Ethan Atkins Date: Thu, 30 Jul 2020 14:43:22 -0700 Subject: [PATCH 2/2] Stop instrumenting scripted The commit 388ed641fbf89227f3cb19e3dd0f18d1be6ee9aa added an autoplugin that was compiled for every scripted test. Compiling autoplugins introduces a fair bit of overhead because it can easily take 3-4 seconds to compile with a cold compiler and even a warn compiler takes a second or so. Removing the instrumentation caused 3 tests to fail: 1. genereated-root-no-publish relied on setUpScripted modifing the project name. Explicitly setting the name in the project build.sbt fixed it. 2. cp-order I'm not sure why this change broke that test, but changing the coursier classpath ordering setting does not automatically trigger a reload on the next update. I have a more involved change that makes changing coursier settings invalidate the update cache but I'm markign the test as pending for now. It could be fixed by adding a call to `update` after `set csrConfiguration ~= (_.withClasspathOrder(false))` but I think it's better that the test actually reflect the expected behavior until I push the fix. 3. auto-plugins there was a hack that seemed added to address https://github.com/sbt/sbt/issues/3164. I cannot tell from either the issue or the linked PR what was going on and since removing the lines that were explicitly commented as being temporary fixed it, I figured it was ok to remove them.
