- Line 118: Update the register_runtime_view callback documentation to mark it
as available from ABI 3 onward, and separately document that its db_kind field
requires ABI 4 or newer, keeping the ABI 3 behavior accurate.
In `@docker/images/proxysql/suse-compliant/entrypoint/entrypoint.bash`:
- Line 51: Validate that PROXYSQLAWSIAM=1 is only accepted when PROXYSQL40=1,
rejecting the combination before any make invocation. In
docker/images/proxysql/suse-compliant/entrypoint/entrypoint.bash lines 51-51,
validate before appending to EXTRA and keep RPMBUILD_WITH_AWS_IAM tied to that
validated state; apply the same validation before the make calls and AWS staging
block in docker/images/proxysql/tarball-compliant/entrypoint/entrypoint.bash
lines 30-30.
In `@lib/ProxySQL_PluginManager.cpp`:
- Around line 192-198: Update get_aws_iam_limits_service so max_waiters_per_key
uses a stricter limit than max_total_waiters, preventing one key from consuming
all waiter slots; derive it from an appropriate smaller bound or a dedicated
admin-configurable variable while preserving the existing total limit behavior.
In `@test/tap/tests/unit/aws_iam_plugin_load_unit-t.cpp`:
- Around line 6-8: Add test_globals.h and test_init.h to the unit test and
initialize the standard custom unit-test harness before any
ProxySQL_PluginManager lifecycle calls, preserving the existing AWS IAM and TAP
test setup.

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: 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: 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: 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...`.)

Do not change an individual entry field, such as `refreshing`, to `std::atomic<bool>` without also establishing valid C++ object construction and destruction for the entry type. `__sync_bool_compare_and_swap` is supported by ProxySQL clang targets and is already used in common code, so it is acceptable for the query-cache soft-TTL refresh claim.

Learning: In ProxySQL, the MySQL_Logger and PgSQL_Logger destructors run after all worker threads have been joined during shutdown. The sequence in src/main.cpp is: (1) join all worker threads, (2) call ProxySQL_Main_shutdown_all_modules() which deletes the loggers. Therefore, there is no concurrent thread access during logger destruction, and lock ordering in the destructors cannot cause deadlocks.

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.

New `stvar` counters should follow this established contract unless their ownership becomes cross-thread.

Make the register_runtime_view ABI requirement consistent.
Line 118 states that ABI 3 adds register_runtime_view. The later callback section labels it as ABI 4+. Label the callback as ABI 3+ and state that only db_kind requires ABI 4+.

Set a stricter per-key IAM waiter limit.
max_waiters_per_key equals max_total_waiters, so one endpoint/user key can consume every waiter slot. Derive the per-key limit from a smaller bound or expose it as a separate admin variable.

Initialize the custom unit-test harness.
This test links libproxysql.a and exercises ProxySQL_PluginManager lifecycle state. It does not include test_globals.h or test_init.h. Add both headers and initialize the standard unit-test harness before the plugin lifecycle calls.
As per coding guidelines, “Unit tests in test/tap/tests/unit/ must use test_globals.h and test_init.h with the custom unit-test harness.” Based on learnings, these headers are required for tests that exercise components linked against libproxysql.a.

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: 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: 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 ProxySQL's unit test directory (test/tap/tests/unit/), test_globals.h and test_init.h are only required for tests that depend on the ProxySQL runtime globals/initialization (i.e., tests that exercise components linked against libproxysql.a). Pure data-structure or utility tests (e.g., ezoption_parser_unit-t.cpp, gtid_set_unit-t.cpp, gtid_trxid_interval_unit-t.cpp) only need tap.h and the relevant project header — omitting test_globals.h and test_init.h is correct and intentional in these cases.

Learning: In `docs/superpowers/plans/2026-08-11-ed25519-authentication.md`, the historical-artifact notice states that embedded expected outputs are plan-time values. Review-driven changes can modify the MariaDB Ed25519 implementation and TAP assertion counts after the plan is written. The shipped implementation and tests are authoritative, so reviewers must not require retroactive synchronization of plan-time expected outputs.

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.

Learning: In ProxySQL's lib/mysql_connection.cpp, `SHOW WARNINGS` detection for both `update_warning_count_from_connection()` and the `add_eof()` call in `ASYNC_USE_RESULT_CONT` intentionally uses `myds->sess->CurrentQuery.QueryParserArgs.digest_text` (comment-stripped digest text). This means the fix/feature does not work when `mysql-query_digests_keep_comment=1` (digest_text contains comments) or `mysql-query_digests=0` (digest_text is unavailable) — these configurations are explicitly excluded from the regression test for `reg_test_5306-show_warnings_with_comment-t`. This design is consistent across the codebase and is an accepted, documented limitation.

Declare the plugin build as a linkage prerequisite.
CI invokes aws_plugin_linkage-t and aws_plugin_load_unit-t together with -j. aws_plugin_linkage-t can run before aws_plugin_load_unit-t builds the plugin. It then fails at Line 22 even though the same invocation builds the plugin. GNU make runs independent recipes concurrently when -j is enabled. (gnu.org)

💡 Performance: curl .a checksum in AWS SDK build identity may cause spurious rebuilds
build-sdk.cmake now folds file(SHA256 ${AWS_CURL_LIBRARY}) into the effective build identity used to skip the (very expensive) AWS SDK rebuild. Static ar archives are not reproducible by default (they embed member mtimes/uids), so any time libcurl.a is regenerated its digest changes even when the curl code is identical, forcing a full AWS SDK core+rds rebuild. This mostly affects incremental/dev builds where curl is rebuilt; consider keying the identity on the curl source/version or a deterministically-built archive instead of the raw .a bytes.

When more than 1,024 IAM completions reach one worker between drains, this branch silently discards otherwise successful results even though the token manager already accepted the corresponding requests. This is reachable when mysql-max_connections exceeds 1,024—the default configuration is 2,048—and sessions are unevenly distributed or complete in a burst; the affected sessions remain registered in aws_iam_waiters until their five-second deadlines and then fail with a misleading token timeout. Size this inbox consistently with the configured waiter limit or propagate overflow as an immediate failure rather than losing accepted completions.

After an in-process ProxySQL reload, the AWS plugin installs a new token manager whose counters restart at zero, while these Prometheus Counter objects retain the old values. Because updates only increment when the new snapshot exceeds the retained value, the metric freezes until the new manager repeats the entire pre-reload count and then under-reports by that previous amount (for example, 100 requests before reload plus 50 after still reports 100). Maintain a per-provider offset or add deltas so these advertised cumulative counters remain correct across the existing reload path.

P1: The 'Chosen dependency approach' section claims a PROXYSQLAWSIAM build gate with the SDK supplied by the system and ProxySQL not vendoring it, but the implementation ships a vendored static-linked plugin. The repo vendors AWS SDK C++ 1.11.869 via Git LFS (deps/aws-sdk-cpp), statically links it into plugins/aws/ProxySQL_Aws_Plugin.so (AWS_SDK_CPP_SHARED := 0), built under PROXYSQL40=1, and no PROXYSQLAWSIAM macro exists. This misdescribes the actual build/packaging path and would mislead operators; update the section to match the vendored static plugin build and remove the PROXYSQLAWSIAM gate.

P3: Several assertions rely on fixed wall-clock sleeps (sleep_for(20ms), sleep_for(30ms)) and a 2s wait_for timeout to coordinate real threads with real-time blocking deadlines (30ms/10ms). Under loaded or sanitizer (ASan/TSan) CI these are timing races and can flake, e.g. the requests == 2 count or a blocking TIMEOUT boundary. Prefer an event-driven latch (like the dispatch/finish pauses already used elsewhere) so each assertion waits on a notified condition rather than a sleep.

P3: wake_count() permanently flips the pipe read-end to non-blocking without restoring the prior file-status flags and ignores the fcntl result. In this file each PipePair is used once so it is harmless today, but restoring the flags (and checking the return) keeps the helper side-effect free and consistent with the constructor.

P3: This test only verifies that the IAM password warning is not emitted for an invalid policy; it never exercises the positive branch where a valid aws_iam backend with a nonempty password produces the warning. The negative assertion also depends on proxy_warning writing to raw stderr (the capture redirects fd 2), so if the warning is routed elsewhere the absence assertion passes vacuously and the warning guard can regress without this test catching it. Add a positive case asserting the warning text appears when the policy is valid AWS_IAM with a configured password.

P3: aws_iam_connection_secret/session_state/pool/failure/kill_helper are added to UNIT_TESTS unconditionally, yet their -Wl,--wrap=... link flags are only appended under ifeq ($(UNAME_S),Linux). On macOS/FreeBSD these targets are still built by the default all goal through the pattern rule but without the wraps, so they link/run with the real Connector/C calls instead of the test's __wrap_* helpers and no longer exercise what the comments describe. Move these five targets into the Linux conditional (or the same guard as their link flags) so they only build where the wrapping is applied.

P3: The helper and its state variable are named with an arbitrary "task11" suffix that does not correspond to any task in this file. The surrounding sync test that this block extends is named after issue 2687 (e.g. mysql_hostgroup_attributes_sync_test_2687), so "task11" is misleading when reading or grepping the file. Rename to reflect the IAM-policy cleanup purpose, e.g. restore_iam_mysql_users / iam_mysql_users_backup_stage.

P3: make -C lib clean immediately after the full make -j deletes the library that was just built and forces a redundant full rebuild when the subsequent unit-test make rebuilds libproxysql.a. No source changed in between; remove the clean (or omit the preceding full build) to avoid the wasted rebuild cycle.

P3: The inline nm checks duplicate verification already performed by the Makefile targets aws_plugin_linkage-t (daemon Aws:: check) and aws_plugin_build (RDS-signer grep), both of which this same step already invokes. Keeping the same assertions in two places lets them drift. Drop the redundant nm/RDS-signer greps from the inline block and keep only the unique ldd DSO check, or fold that check into aws_plugin_linkage-t.

Adds opt‑in AWS IAM authentication for RDS/Aurora MySQL backends via the v4
ProxySQL_Aws_Plugin.so. Previously backends used stored passwords; opted‑in users now authenticate with short‑lived IAM tokens over TLS with SNI. Behavior changes include a dedicated async token‑wait state, IAM‑aware pool identity, and a single validated 1045 retry; password mode is unchanged and IAM never falls back to passwords.COM_CHANGE_USERreuse; allows one fresh‑token retry on 1045 only.AwsIam_*admin rows and label‑freeproxysql_mysql_aws_iam_*Prometheus metrics; SDK‑off builds expose the same metrics at zero.ProxySQL_Aws_Plugin.sowithPROXYSQL40=1, installs AWS attribution files, orders vendoredlibcurlbefore the SDK, gates SDK‑free linkage, and adds focused feature builds.aws_iam_regionon the hostgroup; SDK‑off reports asupport_not_compileddiagnostic; no password fallback.Rollout
