Alessandro Solimando commented on CALCITE-5501: ----------------------------------------------- [@ResourceLock|https://junit.org/junit5/docs/current/api/org.junit.jupiter.api/org/junit/jupiter/api/parallel/ResourceLock.html] from JUnit5 to the rescue here, I have updated my [PR|https://github.com/apache/calcite/pull/3049] by making _SqlToRelConverterExtendedTest_ and _SqlToRelConverterTest_ classes __ run sequentially, while __ keeping their execution w.r.t. the other classes and for the test cases within them, parallel. Running "./gradlew assemble --no-build-cache cleanTest :core:test" repeatedly on the main branch and with the PR on my machine did not provide noticeable difference in the total execution time, because the tests from the two classes are still executed in parallel with all the rest of the tests, the two classes simply don't step on each other toes anymore. I will check in the ML if there is still time to fix this before the release, or if it will wait for main to be open again. > SqlToRelConverterTest.checkActualAndReferenceFiles fails intermittently in > Jenkins CI > ------------------------------------------------------------------------------------- > > Key: CALCITE-5501 > URL: https://issues.apache.org/jira/browse/CALCITE-5501 > Project: Calcite > Issue Type: Bug > Components: tests > Affects Versions: 1.32.0 > Reporter: Stamatis Zampetakis > Priority: Major > Labels: pull-request-available > Time Spent: 1.5h > Remaining Estimate: 0h > > Sample runs that failed due to > SqlToRelConverterTest.checkActualAndReferenceFiles: > * > https://ci-builds.apache.org/job/Calcite/job/Calcite-sonar/job/main/15/console > * > https://ci-builds.apache.org/job/Calcite/job/Calcite-sonar/job/main/18/console > -- This message was sent by Atlassian Jira (v8.20.10#820010)
