Pull request overview
This PR adds a dedicated local integration-test harness for --move-tables mode, including CI coverage via a new GitHub Actions workflow and a Docker-based dual-cluster (source/target) MySQL test environment.
Changes:
- Introduces a new
localtests/move-tables-test.shharness plus initial end-to-end move-tables test cases (single,single-concurrent-writes). - Adds
script/docker-gh-ost-move-tables-testsand updates move-tables helper scripts to support the dual-cluster setup and configurable database name. - Adds a new CI workflow to run move-tables tests across a MySQL/Percona version matrix, and excludes
move-tablesfrom the existinglocaltests/test.shrunner.

is this only running single right now? Quick pass I can't tell where single-concurrent-writes is called

oh i see in the CI output that it's running it, so maybe i'm just missing how that's populated. Assuming it's reading the move-tables directory

Yeah, test_all looks for all of the directories at the configured path
tests_path=$(dirname $0)/move-tables

I'm planning more sophisticated tests to validate cutover state (e.g. crash safety), throttling, etc. in a separate PR. ↩
