📝 WalkthroughWalkthroughThe PR adds Aurora MySQL blue/green deployment schemas, runtime synchronization, production-shaped monitoring queries, shared AWS BGD simulator services, and lifecycle test coverage. It also renames shared simulator APIs and preserves existing RDS BGD scenarios. ChangesAurora BGD implementation
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR changes Aurora blue/green configuration, runtime status, and switchover behavior, but unresolved issues can drop valid deployments from runtime configuration, publish invalid status values, and make rollback behavior inconsistent during a switchover. These correctness and operational risks should be fixed before merge. Poem

In
`@docs/superpowers/specs/aws-aurora-blue-green/2026-07-31-aurora-bgd-cluster-simulator-testing-design.md`:
- Around line 336-338: Update the monitor/FSM simulator scenarios covering
random blue-member topology and green-member target probes to use a per-scenario
deterministic seed, and include that seed in failure diagnostics. Ensure all
randomized probe selection derives from that scenario seed so repeated runs
produce the same waits and probe sequence.
- Around line 359-362: Resolve the contradiction between the resilience scenario
and the Non-Goals section: either define which deployment/FSM state is persisted
and the exact worker restart or respawn boundary that restores it, or remove the
worker-restart retention scenario from the resilience requirements. Update both
the listed scenario and the corresponding Non-Goals text consistently.
- Around line 65-71: Update the schema definitions for topology_present,
replica_table_present, IS_CURRENT, and both encrypted columns to enforce binary
values with CHECK constraints limiting each value to 0 or 1; if constraints are
intentionally omitted, explicitly document controller validation as
authoritative.
- Around line 74-76: Update the topology control-state specification to define
precedence independently for table-check and metadata queries, including the
outcome when topology_present=0 and error_code is nonzero. Clarify that
replica_table_present=0 takes precedence over error_code, and add matrix tests
covering both control-state combinations while preserving the existing
successful empty-result behavior.
In
`@docs/superpowers/specs/aws-aurora-blue-green/2026-07-31-aurora-bgd-configuration-runtime-cluster-sync-design.md`:
- Line 176: Update the documentation wording at the referenced validation
statements to use “result set” consistently, replacing “resultset” at both
occurrences without changing the surrounding meaning.
- Around line 173-177: Clarify the invalid-row loading requirement in the Aurora
monitor resultset design by selecting one atomic policy: reject the entire load
or isolate invalid rows per row. Define the resulting admin error details,
including the writer hostgroup and conflicting fields, and specify the
rollback/publish behavior so no partial runtime reconfiguration occurs.
- Around line 220-234: Replace the “restart/refresh” behavior for the affected
Aurora writer-hostgroup worker with an explicit in-place refresh or atomic state
transfer. Preserve the active BGD FSM state, cached member identities, applied
DNS pins, and completion-latch state while applying the updated staging
configuration, ensuring the operation does not restart from NONE.
- Around line 105-111: Standardize the admission table and related tests on the
canonical ProxySQL variable name mysql-aws_blue_green_deployment_auto_discovery,
replacing aws_blue_green_deployment_auto_discovery wherever it refers to this
setting. Keep the documented behavior and table values unchanged.
- Around line 110-111: Define the inactive-transition behavior in the design,
covering worker teardown, pin cleanup, bgd_status updates, and terminal-latch
handling when active changes to 0 during an ongoing switchover. Add a
deterministic test for this transition and ensure routing state cannot remain
applied after the worker stops.
In
`@docs/superpowers/specs/aws-aurora-blue-green/2026-07-31-aurora-bgd-monitor-fsm-design.md`:
- Around line 147-155: Update the FSM’s cutover snapshot handling so production
membership is freshly captured at cutover rather than relying on the stored
normal-probe snapshot, and prevent incomplete target queries from reusing an
outdated target map. Associate both snapshots with the deployment/member-set
generation, and require a complete, generation-matching snapshot before
permitting the first traffic redirection.
- Around line 80-85: Update the bootstrap validation and deployment-fingerprint
requirements to reject TARGET snapshots with an empty or missing TARGET id.
Ensure the fingerprint uses this validated id alongside the existing endpoint
and port, preserving safe repeated-completion detection and rearming.
- Around line 434-454: Update the SWITCHOVER_COMPLETED transition and its
cleanup flow to require all member pinning and draining actions to be complete
before removing DNS pins, releasing the active member map, and resuming normal
monitoring. If completion can arrive with incomplete actions, route it through a
safe late-entry path that retries only unapplied actions and defers cleanup
until they succeed; add coverage for partial action failure before completion.
- Around line 349-365: Define explicit topology row-shape predicates before the
FSM transition rules, covering SOURCE-only, SOURCE-plus-TARGET, duplicate rows,
and TARGET-only results. Specify which shapes are valid, how each maps to state
handling, and require validation before publishing status or performing cleanup;
prevent mixed or incomplete results from triggering premature cleanup or leaving
pins and suspended monitoring active indefinitely.

Learning: In ProxySQL (lib/ProxySQL_Cluster.cpp and related cluster sync code), the MySQL server status value `SHUNNED_AWS_BGD` is runtime-only. Both `SHUNNED` and `SHUNNED_AWS_BGD` are normalized to `ONLINE` before being exposed/checksummed for cluster synchronization, so case-mismatched or unexpected status strings for these states are not expected to reach the `mysql_servers_v2` insert path (e.g., in `pull_mysql_servers_v2_from_peer`) during normal cluster sync operation.

File: lib/MySQL_Session.cpp:0-0
Timestamp: 2026-07-10T02:12:40.310Z
Learning: In lib/MySQL_Session.cpp, mysql_query_rules.attributes.destination_schema (query-rule-driven session schema switching) is applied unconditionally, without the `transaction_persistent_hostgroup == -1` guard used for `destination_hostgroup`. This is intentional: switching a session's default schema mid-transaction via COM_INIT_DB has the same semantics as a client issuing `USE <schema>` mid-transaction through ProxySQL — it does not commit or invalidate the transaction and the sticky backend connection is preserved. Guarding on `transaction_persistent_hostgroup` was considered but rejected because it would make the destination_schema rule silently inert during an active transaction, which was judged more surprising than the current behavior.

Learning: When using GitHub-flavored Markdown headings, be aware that an em-dash surrounded by spaces (written as ` — `) affects the generated anchor/slug: GitHub replaces spaces with hyphens and removes non-alphanumeric punctuation, which can produce double hyphens (e.g., `## Foo — bar` → anchor `#foo--bar`, not `#foo-bar`). If you reference these anchors (e.g., internal links), ensure the expected slug matches this behavior.

Learning: When reviewing GitHub-flavored Markdown links/anchors, remember that heading-to-anchor slug generation treats spaces as hyphens and removes punctuation. If a heading contains an em-dash surrounded by spaces (e.g. ` — `), the slugs can legitimately include a double hyphen where the two surrounding space-runs become `-` on either side of the removed em-dash (e.g. `...vocabulary--read...`). Do not flag double-hyphens in anchor links for em-dash-containing headings as errors; they reflect GitHub’s correct slug behavior.

Learning: For ProxySQL isolated regression tests that use a fresh explicit `INFRA_ID`, `test/infra/control/ensure-infras.bash` detects the absent `proxysql.${INFRA_ID}` container and invokes `test/infra/control/start-proxysql-isolated.bash` before it provisions configuration. Do not invoke `start-proxysql-isolated.bash` again after `ensure-infras.bash`, because it removes the named container and its `proxysql.db`, which discards the provisioned configuration. The binary at `src/proxysql` is mounted when the container is initially created.

Learning: In `lib/DNS_Cache.cpp`, `DNS_Cache` pinning (`pin()`/`unpin()`) is currently only invoked by AWS RDS BGD monitor worker threads (one worker per writer hostgroup/BGD deployment). Since there is only one class of thread pinning a given hostname, concurrent re-pinning races (e.g., a TOCTOU between `lookup()`'s expired-pin detection and `unpin()`'s clear) are not currently reachable in practice, even though `unpin()` clears the pin unconditionally without verifying it matches a specific snapshot.

9-12: LGTM!
35-39: 🩺 Stability & AvailabilityMake the single-controller CI rule executable.
The design requires one test binary per ProxySQL instance, but it registers multiple binaries in the same CI groups without stating how the runner enforces serialization or assigns isolated instances.
Simulator tables and full cleanup are instance-global. Parallel binaries can delete or read each other’s state. Add the runner guarantee to this contract and verify it in CI.

Lines 124-125 and 416 explicitly remove a target-writability gate. Lines 118-120 also state that the observed ordering is not a formal AWS guarantee. If POST_PROCESSING can appear before the target writer is writable, Line 417 routes writes to a read-only target.

@codex review commits 3d9c54a through 1c3702c. Focus on the Phase 2 simulator contract, production-query compatibility, accepted-backend routing, atomic state publication, and regressions. The simulator is test infrastructure; evaluate it through the existing Aurora and RDS consumers rather than requiring simulator self-tests. [Drafted by Codex · AI agent] |

617-620: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftBind active cleanup to the deployment's original green pools.
Completion cleanup uses configured green hostgroups, while this section allows those hostgroups to change during an active deployment. A change before completion can leave the old green pools undrained or drain pools that did not belong to the active deployment.
Snapshot the green hostgroup and pool identities when the deployment is admitted, and use those identities for rollback and completion cleanup. Alternatively, reject these configuration changes while a deployment is active.

443-449: 🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy liftGate the completed latch on successful cleanup.
The specification does not define what happens when DNS removal, pool purge, writer reconciliation, or green-pool draining fails. The worker can release the member map and enter
SWITCHOVER_COMPLETEDafter partial cleanup, which prevents later retries and can leave stale routing state.Keep the member map until all required cleanup effects succeed, or add a recoverable cleanup state that retries incomplete actions. Add failure-injection coverage for each cleanup operation.

In `@lib/MySQL_HostGroups_Manager.cpp`:
- Around line 4182-4195: Update
MySQL_HostGroups_Manager::update_aws_aurora_bgd_status to validate bgd_status
before preparing or executing the UPDATE, accepting only the documented Aurora
BGD FSM state names and ignoring unknown values as promised by the header
declaration.
- Around line 196-223: Update the cross-row validation pass in the
row-validation logic so rows rejected for cross-row conflicts no longer
participate as active “other” rows; repeatedly run the pass until no additional
rows are rejected, preserving locally invalid-row handling and ensuring only the
final non-rejected rows influence conflict checks. Adjust test_row_validation
expectations if the implementation retains symmetric rejection for mutually
conflicting pairs.
In `@test/deps/cluster_simulator/lib/aurora_utils.cpp`:
- Around line 454-470: Change the cleanup parameter and related branching in the
enclosing utility function to use bool semantics, since current callers pass
values that both select full cleanup. Remove the ineffective
hostgroup_attributes-based distinction and preserve the full-delete behavior
through the boolean cleanup path; retain per-replica-set cleanup only if
required by an explicitly supported false value.
In `@test/tap/tap/Makefile`:
- Around line 86-96: Update the Makefile prerequisites for bgd_simulator.o,
aurora_bgd_simulator.o, and rds_bgd_simulator.o: add tap.h and command_line.h to
bgd_simulator.o, and add cluster_simulator.h, utils.h, and command_line.h to
both aurora_bgd_simulator.o and rds_bgd_simulator.o. Leave the libtap_mariadb.a

Learning: In ProxySQL's TAP test suite, resource leaks (e.g., not calling mysql_close() on early return paths) are commonly tolerated because test processes are short-lived and OS frees resources on exit. This pattern applies to all C++ test files under test/tap/tests. When reviewing, recognize this as a project-wide test convention and focus on test correctness and isolation rather than insisting on fixing such leaks in these test files.

Learning: In ProxySQL unit tests under test/tap/tests/unit/, include test_globals.h and test_init.h only for tests that depend on ProxySQL runtime globals/initialization (i.e., tests that exercise components linked against libproxysql.a). For “pure” data-structure/utility tests (e.g., ezoption_parser_unit-t.cpp, gtid_set_unit-t.cpp, gtid_trxid_interval_unit-t.cpp) that do not require runtime globals/initialization, it is correct to omit test_globals.h and test_init.h and instead include only tap.h plus the relevant project header(s).

Learning: When reviewing ProxySQL cluster sync code that populates/updates `mysql_servers_v2` (e.g., paths like `pull_mysql_servers_v2_from_peer` and other cluster sync logic), remember that the MySQL server status `SHUNNED_AWS_BGD` is runtime-only: for cluster synchronization it is normalized together with `SHUNNED` to `ONLINE` before values are exposed/checksummed for synchronization. Therefore, during normal cluster sync operation you should not expect case-mismatched or “raw” `SHUNNED`/`SHUNNED_AWS_BGD` strings to reach the `mysql_servers_v2` insert/update path—if they do, treat it as evidence that the normalization step was bypassed or altered (and verify the normalization logic and call flow).

Learning: When validating GitHub-rendered Markdown in this repository (e.g., links that use heading anchors), account for GitHub slug behavior for headings containing an em-dash (—) surrounded by spaces: GitHub strips the em-dash and converts each surrounding space into a hyphen independently, which can produce a double hyphen (--) in the generated anchor. Therefore, do NOT flag as broken links any anchors whose expected slug contains a double hyphen specifically attributable to an em-dash surrounded by spaces in the source heading. (Example: `...vocabulary — read...` -> `...vocabulary--read...`.)

Learning: When using GitHub-flavored Markdown headings, be aware that an em-dash surrounded by spaces (written as ` — `) affects the generated anchor/slug: GitHub replaces spaces with hyphens and removes non-alphanumeric punctuation, which can produce double hyphens (e.g., `## Foo — bar` → anchor `#foo--bar`, not `#foo-bar`). If you reference these anchors (e.g., internal links), ensure the expected slug matches this behavior.

Learning: When reviewing GitHub-flavored Markdown links/anchors, remember that heading-to-anchor slug generation treats spaces as hyphens and removes punctuation. If a heading contains an em-dash surrounded by spaces (e.g. ` — `), the slugs can legitimately include a double hyphen where the two surrounding space-runs become `-` on either side of the removed em-dash (e.g. `...vocabulary--read...`). Do not flag double-hyphens in anchor links for em-dash-containing headings as errors; they reflect GitHub’s correct slug behavior.

Learning: In `docs/superpowers/specs/aws-aurora-blue-green/2026-07-31-aurora-bgd-monitor-fsm-design.md`, Aurora BGD normal monitoring refreshes the production membership snapshot while the deployment is `AVAILABLE`. When `SWITCHOVER_INITIATED` is accepted, the monitor freezes the last complete production snapshot for the active switchover because AWS does not permit modifying included DB clusters during that period. The target-membership probe continues, and routing requires a complete target map for the frozen production member set.

Column 2 rewrites
SESSION_IDto'probably_former_MASTER_SESSION_ID'when the row is not the newestMASTER_SESSION_IDrow. Column 4 still tests the base columnSESSION_ID, because MySQL resolves a select-list reference to the base column and not to the alias defined earlier in the same list. A stale row whose baseSESSION_IDis'MASTER_SESSION_ID'therefore returnsREPLICA_LAG_IN_MILLISECONDS = 0even though column 2 marked it as a former master.The lag value feeds reader placement and lag actions, so a stale former writer can be treated as a zero-lag reader. If that is not intended, apply the same freshness test in column 4.
🐛 Proposed fix to align the lag normalization with the identity rewrite

Code Review ✅ Approved 4 resolved / 4 findingsAdds AWS Aurora blue/green deployment support with green hostgroups, runtime status publication, and shared simulator tests, addressing the bgd_status cluster checksum pollution, NONE-state cadence conflicts, and Aurora replica timestamp filter issues. ✅ 4 resolved✅ Quality: NONE-state cadence conflicts with discovery bootstrap steps
✅ Bug: bgd_status pollutes aurora cluster checksum (SELECT *)
✅ Bug: Aurora replica timestamp uses local time but SQLite filter uses UTC
✅ Bug: GloMyMon null check removed before mutex lock

Summary
This draft introduces the approved design contracts for AWS Aurora MySQL
blue/green deployment support in the existing Aurora monitor.
The design is split into:
Development approach
Implementation will proceed on this draft PR in three review-gated phases:
Each behavior change will follow red-green-refactor. Simulator coverage proves
ProxySQL's response to recorded AWS observations; final acceptance will run
ProxySQL against a real Aurora blue/green deployment before this PR is made
ready to merge.
Current scope
This initial revision contains design documents only. Production implementation
has not started.
Validation
Design approved.Summary by cubic
Adds AWS Aurora MySQL blue/green deployment support and moves tests to a shared AWS BGD simulator with explicit publication modes. Keeps
bgd_statusruntime-only while persisting new green hostgroups.green_writer_hostgroup/green_reader_hostgroupwith paired-NULL and conflict validation; persists green hostgroups on SAVE and ProxySQL Cluster sync. Publishesbgd_statusat runtime only and excludes it from SAVE, cluster sync, and cluster checksum. Adds an explicit Aurora replica-status query and unit tests.ProxySQL_Config,ProxySQL_Admin, checksum, and dumps. Online disk upgrade adds green columns tomysql_aws_aurora_hostgroupsfromV2_0_10.runtime_mysql_aws_aurora_hostgroupsincludes green columns; peer pull/write persists them. Cluster checksum ignoresbgd_status.AWS_BGD_*) and adds an Aurora replica-set service with publication modes (replace sets, retain-backends snapshot, reset scenario). Migrates RDS tests to the shared simulator, adds Aurora unit/upgrade tests, and removes the legacyaurora.cpp.bgd_statuspublisher contract.Rollout
V2_0_10; no manual SQL required.Written for commit 49c1c29. Summary will update on new commits.
