From 9df01729a0cd85978935dc6bb88f563a9f911bd9 Mon Sep 17 00:00:00 2001 From: David Porter Date: Wed, 26 Aug 2026 09:33:28 -0700 Subject: [PATCH] fix: [Scheduler] V1->V2 migration-eligibility fix and migrated-start ID (#11462) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ### Summary Combines #11134 and #11427 as two distinct fixes affecting V1 schedules and requiring a version bump. they're joined together. Shipping them separately would require two separate version-bump deploys for the "same" version number. This merges both behavioral changes under one shared v13: - **`RefreshBeforeMigrationCheck`** (from #11134): This fixes a problem that was preventing v1->v2 migration from ever succeeding under default configuration - **`PreserveMigratedStartIDs`** (from #11427): Try and keep the requestIDs from when workflows are started under when a rollback occurs. - Adds a third guard while in this space: Guards against late migrations that occur when a transient error bounces a v1>v2 migration and the schedule goes back to sleep and then attempts to migrate again. Following #11134's two-phase-rollout rationale, this PR only teaches the scheduler to *understand* v13 for safe replay/rollback: both fixes are gated behind `hasMinVersion(13)`, but `CurrentTweakablePolicies.Version` stays at `TriggerImmediatelyTimestamp` (12). A follow-up deploy bumps `Version` to 13 to activate both fixes at once — a single activation instead of two. #### Details - `service/worker/scheduler/workflow.go`: adds `RefreshBeforeMigrationCheck` and `PreserveMigratedStartIDs`, both `= 13`, with a shared doc comment; adds a `// TODO` on `CurrentTweakablePolicies.Version` pointing at the follow-up activation deploy; ports both fixes' logic unchanged (gated on the respective constant). - `service/worker/scheduler/workflow_test.go`: ports all three new tests from the two source PRs (`TestAutoMigrateReconcilesRunningWorkflowBeforeCheck`, `TestMigratedBufferedStartPreservesIdempotencyIDs`, `TestMigratedBufferedStartUsesLegacyIDsAtOldVersion`) plus the `TestStart` `RequestId` assertion. `TestMigratedBufferedStartPreservesIdempotencyIDs` now force-sets `CurrentTweakablePolicies.Version` (mirroring the other two version-forcing tests), since `Version` no longer defaults to 13 here. - `service/worker/scheduler/testdata/replay_migration_v1_to_v2.json.gz` and `tests/schedule_migration_v1_to_v2_callback_compat_test.go`: brought in verbatim from #11134. ## How did you test it? - [x] built - [ ] run locally and tested manually - [x] covered by existing tests - [x] added new unit test(s) - [ ] added new functional test(s) `go test -tags test_dep ./service/worker/scheduler/...` passes, including `TestReplays` against the copied fixture and all three new/updated unit tests. `go build`/`go vet` pass for `./service/worker/scheduler/...` and `./tests/...`. ## Potential risks Moderately high risk as this is touching the Schedule V1 code. A problem with nondeterminism could affect schedules quite badly. --------- Co-authored-by: Claude Sonnet 5 Co-authored-by: liam-lowe <56076876+liam-lowe@users.noreply.github.com> Co-authored-by: alex.stanfield <13949480+chaptersix@users.noreply.github.com> Co-authored-by: Stephan Behnke Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: michaely520 Co-authored-by: Feiyang Xie Co-authored-by: Kannan Co-authored-by: Fred Tzeng <41805201+fretz12@users.noreply.github.com> Co-authored-by: Lakshay <54310363+Lakshaymiddha@users.noreply.github.com> Co-authored-by: samm Co-authored-by: Quinn Klassen Co-authored-by: Will Duan Co-authored-by: Qian Chen Co-authored-by: Prathyush PV Co-authored-by: Sean Kane Co-authored-by: mavemuri <74267563+mavemuri@users.noreply.github.com> Co-authored-by: Rodrigo Zhou Co-authored-by: Brian VanLoo Co-authored-by: akbala Co-authored-by: Dan Davison Co-authored-by: Chris Smith --- service/worker/scheduler/activities.go | 10 + service/worker/scheduler/activities_test.go | 68 ++- service/worker/scheduler/fx.go | 1 + .../replay_migration_v1_to_v2.json.gz | Bin 0 -> 3902 bytes service/worker/scheduler/workflow.go | 48 +- service/worker/scheduler/workflow_test.go | 575 ++++++++++++++++++ tests/schedule_migration_test.go | 225 +++++++ 7 files changed, 921 insertions(+), 6 deletions(-) create mode 100644 service/worker/scheduler/testdata/replay_migration_v1_to_v2.json.gz diff --git a/service/worker/scheduler/activities.go b/service/worker/scheduler/activities.go index 1f9c7a7d01..ec0b0739b0 100644 --- a/service/worker/scheduler/activities.go +++ b/service/worker/scheduler/activities.go @@ -38,6 +38,7 @@ type ( startWorkflowRateLimiter quotas.RateLimiter maxBlobSize dynamicconfig.IntPropertyFn localActivitySleepLimit dynamicconfig.DurationPropertyFn + migrationEnabled dynamicconfig.BoolPropertyFn } errFollow string @@ -394,6 +395,15 @@ func (a *activities) MigrateScheduleToChasm(ctx context.Context, req *schedulerp nil, ) } + if a.migrationEnabled != nil && !a.migrationEnabled() { + // A live (uncached) check, deliberately re-read here rather than + // trusting the caller's possibly-stale view: this is what stops a + // pending migration from completing after EnableCHASMSchedulerMigration + // has been rolled back, even if the workflow retrying it has been + // asleep since well before the rollback.
