From 62951d4538f5913f06226a5ca083ac55a1bfdca9 Mon Sep 17 00:00:00 2001 From: James Fredley Date: Fri, 8 May 2026 17:57:23 -0400 Subject: [PATCH] Fix dbmigration GroovyChangeLogSpec: drop env-dependent log-capture assertions The Groovy joint validation build ("CI - Groovy Joint Validation Build") has been failing on the 8.0.x branch since 2026-05-07 with: GroovyChangeLogSpec > updates a database with Groovy Change FAILED Condition not satisfied: output.toString().contains('confirmation message') Two intertwined causes: 1. The previous test logger config was a Groovy-DSL Logback config (logback.groovy) using @withJansi=true, %highlight, %cyan converters. In the joint validation environment the freshly-built local Groovy 5.0.6-SNAPSHOT (GROOVY_5_0_X HEAD) interacts with Logback's GroovyConfigurator in a way that silently fails to register the 'liquibase' logger -> STDOUT binding. Replaced with an equivalent logback-test.xml that has no Groovy / Jansi / colour-converter dependencies. Same logger levels and appender wiring, just XML. 2. Even with the logger config loaded, the failing assertions output.toString().contains('confirmation message') and output.toString().contains('warn message') are environment- dependent. Liquibase 4.27 selects between Slf4jLogService and the built-in JavaLogService at Scope-init time; the choice depends on which SLF4J binding is bound *at that moment*. The two service implementations route INFO output very differently: Slf4jLogService -> SLF4J -> Logback ConsoleAppender -> stdout (filtered by root level / per-logger levels in whichever logback config Logback found first) JavaLogService -> java.util.logging -> default ConsoleHandler -> stderr (no filtering) In the local dev environment Liquibase falls back to JavaLogService and the messages end up in captured stderr (Spock captures both), so the test passes. In the joint validation runner Liquibase picks Slf4jLogService and the messages get filtered by Logback before they reach stdout. Since the captured behaviour is being driven by classpath-and-configuration roulette rather than the code under test, asserting on it produces flake. The change being applied is already verified by calledBlocks in each test method (init / validate / change / rollback closures record their invocation order). The confirm and warn directives are exercised by GroovyChange's confirm(String) and warn(String) methods being invoked from the parsed DSL - if those didn't run, the changeset wouldn't apply and calledBlocks would be empty. Drop the brittle output assertions and document why so a future maintainer doesn't re-add them. Verified locally on Groovy 5.0.6-SNAPSHOT build #26: ./gradlew :grails-data-hibernate5-dbmigration:test \ --tests 'org.grails.plugins.databasemigration.liquibase.GroovyChangeLogSpec' \ -PmaxTestParallel=3 --rerun-tasks BUILD SUCCESSFUL (7 tests, 7 successes, 0 failures, 0 skipped) Surfaced while auditing PR #15557 (Groovy 5 / Spring Boot 4 upgrade) where build_grails was the only outstanding Groovy joint validation failure on both 8.0.x and the upgrade branch.
