📝 WalkthroughWalkthroughThis PR adds a provider-neutral server discovery framework for MySQL and PostgreSQL hostgroups, a plugin ABI extension with module registration and controller lifecycle, clustered module transport for peer synchronization, GenAI runtime locking and atomic MCP variable publication, plus packaging verification, CI workflow updates, and thread-safety and random-generation fixes across core files. ChangesServer Discovery Integration
GenAI Runtime Synchronization
CI, Packaging, and Runtime Safety
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR adds provider-neutral discovery, clustered topology synchronization, and runtime server installation, but unresolved issues can cause resource exhaustion, incorrect server routing, stale hostgroup state, or credential exposure, while persistence failures can leave restart state behind active state. The PR is not merge-ready until these concrete correctness, security, and reliability risks are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

lib/ProxySQL_Cluster.cpp (3)
665-678: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winConsider computing the local module checksums once per interval instead of once per peer.
set_checksumsruns on each cluster monitor thread, one thread per peer. UnderPROXYSQL40line 288 now always issuesquery3, so this block executes for every peer on everycluster_check_interval_mstick. The four local checksums do not depend on the peer. Each call dumps the module tables fromadmindband hashes them while holdingGloAdmin->sql_query_global_mutex, which also serializes all admin queries and the other cluster pull paths.With a larger cluster this adds N× duplicated work and N× contention on that mutex per interval. Consider caching the local per-protocol/version checksum with its own generation or timestamp, and sharing it across peer threads.

The two branches differ only in the reconcile function they call. Each branch repeats
begin_apply, the test hook call, the reconcile call, and theproxysql_materialize_server_desired_setcall in the same order.Both branches must stay in step. A later edit that adds a step to one branch and not the other produces a protocol-specific behavior difference that no compiler check catches.

that invoke save_mysql_servers_runtime_to_database(false) and
flush_GENERIC__from_to for mysql_servers to check their return values and
propagate persistence failures, preventing execution from continuing after a
failed save or flush.
In `@lib/MySQL_HostGroups_Manager.cpp`:
- Line 51: Update the mysql_desired_rows-to-servers_add reconciliation path to
convert numeric row.status values into the accepted ONLINE, SHUNNED,
OFFLINE_SOFT, or OFFLINE_HARD tokens before insertion, preserving shunned and

In `@lib/ProxySQL_Admin.cpp`:
- Around line 3485-3490: Update admin_shutdown() to assign -1 to both pipefd[0]
and pipefd[1] immediately after closing the descriptors, so
proxysql_wake_server_discovery_admin() cannot treat a closed descriptor as
valid.
- Around line 6903-6906: Update the checksum publication flow around
proxysql_server_module_cluster_poll_snapshot_complete so a failed plugin
checksum does not trigger the early return that suppresses
runtime_checksums_values updates. Always publish the core module checksums,
while excluding only the four plugin rows when the plugin snapshot is
incomplete.
- Around line 8399-8401: Update the runtime-install preparation failure path in
the caller around prepare_registered_server_module_runtime so resultsets
converted from MYSQL_RES are cleaned up when the call returns without adopting
them. Ensure both converted resultset sets are released or deleted on rejection,
while preserving ownership transfer when preparation succeeds.
In `@lib/ProxySQL_Cluster.cpp`:
- Line 992: Update the MySQL and PostgreSQL version checks around the visible
module branches so v2 modules do not fall into the legacy version-1 diagnostic
else paths: adjust the control flow involving module_mysql_v2 near the first
check and module_pgsql_v2 near the second to skip legacy sync handling when the
module path handled it, while preserving version-1 diagnostics for non-v2
modules.
- Around line 2618-2626: Prevent leaked converted result sets on module-apply
failure by moving construction of incoming_servers until after the module-apply
block at lib/ProxySQL_Cluster.cpp lines 2618-2626, and applying the same change
to incoming_pgsql_servers at lines 4169-4177; do not alter the successful
load_*_servers_to_runtime paths.
- Line 2335: Correct the subsystem names in the persistence error messages:
update lib/ProxySQL_Cluster.cpp lines 2335 and 2935 to report failed persistence
of mysql_servers, and lines 3924 and 4199 to report failed persistence of
pgsql_servers. Modify only the messages associated with the
save_*_servers_runtime_to_database and flush_GENERIC__from_to operations.
- Around line 2939-2940: Update the messages in the
cluster_mysql_servers_save_to_disk-disabled branch to remove the trailing
“failed.” wording, while preserving the hostname and port context and keeping
both proxy_debug and proxy_info messages consistent.
- Around line 2332-2333: Update the log messages in
pull_runtime_mysql_servers_from_peer to identify the synchronized subsystem as
runtime MySQL Servers rather than MySQL Servers v2, leaving the corresponding
pull_mysql_servers_v2_from_peer messages unchanged.
- Line 2589: Ensure every stored MYSQL_RES* in results is freed when
fetching_error becomes true after query fetching, including the peer module
endpoint error path. Move the results cleanup loop outside the fetching_error ==
false conditional, or otherwise invoke equivalent cleanup before returning,

- Around line 1023-1024: Update the module_mysql_v1 sync condition near
pull_runtime_mysql_servers_from_peer to also require
runtime_mysql_servers_already_loaded to be false. Preserve the existing
mysql_server_sync_algo and module_mysql_v1 checks, preventing a duplicate

- Around line 433-437: Move the five server-discovery
targets—plugin_servers_module_tables_unit-t,
plugin_server_runtime_install_unit-t, plugin_server_reconcile_unit-t,
plugin_server_materialization_unit-t, and
plugin_servers_cluster_transport_unit-t—from the unconditional UNIT_TESTS list
into the existing ifeq ($(PROXYSQL40),1) block so builds without PROXYSQL40 do
not attempt to compile them.
In `@test/tap/tests/unit/plugin_server_reconcile_unit-t.cpp`:
- Around line 12-24: Add the standard functional header to the includes of the
unit test so run_claim_publication_race can use std::function without relying on
transitive includes.
In `@test/tap/tests/unit/plugin_servers_module_tables_unit-t.cpp`:

used by plugin_server_reconcile_unit-t.cpp before exercising
ProxySQL_PluginManager and server discovery behavior.

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).

Timestamp: 2026-01-20T09:34:19.124Z
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.

Preserve the desired server status.
mysql_desired_rows emits numeric status values. servers_add accepts only ONLINE, SHUNNED, OFFLINE_SOFT, and OFFLINE_HARD; an unrecognized value keeps the default ONLINE status. A desired row that is shunned or offline therefore becomes online during reconciliation. This also defeats the merge function’s status-preservation behavior.
Convert row.status to the status token expected by servers_add, or extend servers_add to parse the numeric representation.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift
A single plugin checksum failure suppresses every core module checksum.
proxysql_server_module_cluster_poll_snapshot_complete requires exactly four entries and rejects any entry with an empty checksum. The loop at Lines 6888-6902 skips an entry whenever proxysql_server_module_cluster_poll_checksum fails, so computed_server_module_checksums then holds fewer than four entries and this early return runs.
The early return happens before runtime_checksums_values is rewritten. One transient plugin table read failure therefore stops publishing admin_variables, mysql_query_rules, mysql_servers, mysql_users, and every other core module checksum. ProxySQL Cluster peers then compare against a stale table and stop converging on core configuration that has nothing to do with the plugin.
Publish the core checksums unconditionally. Withhold only the four plugin rows when the plugin snapshot is incomplete.
🐛 Proposed fix to decouple plugin rows from the core dump
if (!proxysql_server_module_cluster_poll_snapshot_complete(
computed_server_module_checksums, server_module_checksums)) {
- return;
+ // Withhold only the plugin rows; the core module checksums are
+ // independent and must keep being published to Cluster peers.
+ proxy_error("Cluster: withholding an incomplete server-module checksum snapshot\n");
+ server_module_checksums.clear();

62-69: 🔒 Security & Privacy | 🔵 Trivial | 💤 Low valueEscaping in test token configuration is incomplete, but exposure is limited to test infrastructure.
The
escape_sql_literal()helper doubles single quotes but does not escape backslashes. If a token containing\'were set via theTAP_MCP_AUTH_TOKENenvironment variable and the admin parser accepted MySQL-style backslash escapes, it could theoretically break out of the quoted string. However, this code path is test-only and the token source is controlled by the test framework (environment variable or hardcoded defaults), not external input. The escaping pattern appears across multiple test files and merits consistency improvement for defense-in-depth, but the practical security impact is limited to test scenarios.To improve robustness, consider using parameterized statement placeholders or connection-aware escaping (
mysql_real_escape_string) if these tokens ever flow from untrusted sources. For the current test-only context, verify thatTAP_MCP_AUTH_TOKENis not set from user input during CI/CD.🤖 Prompt for AI Agents

Learnt from: wazir-ahmed
Repo: sysown/proxysql PR: 5557
File: test/tap/tests/unit/gtid_set_unit-t.cpp:14-17
Timestamp: 2026-04-01T21:27:00.297Z
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).

🌐 Web query:
curl_slist_append returns NULL existing list not freed libcurl documentation
💡 Result:
When curl_slist_append returns NULL, the original list is not freed by the function, and it remains the caller's responsibility to manage its memory [1][2][3]. If you use the common pattern: list = curl_slist_append(list, string); And curl_slist_append fails (returns NULL), you will overwrite your pointer to the existing list with NULL, effectively losing the reference to the previously allocated memory and creating a memory leak [2]. To avoid this, the official libcurl documentation recommends using a temporary variable [1][3]: struct curl_slist temp = curl_slist_append(list, string); if(!temp) { / Failure: the original list is still accessible via 'list' */ curl_slist_free_all(list); return -1; } list = temp; This ensures that if the operation fails, you still have the pointer to the original list, allowing you to free it properly with curl_slist_free_all [1][3].

Preserve the header list when appending authentication.
If the second curl_slist_append() fails, it returns nullptr without freeing the existing list. This assignment loses the Content-Type list, and curl_easy_setopt() receives nullptr for CURLOPT_HTTPHEADER. Store the result in a temporary pointer, handle failure, and use an RAII owner.

Require verified HTTPS before sending bearer tokens.
The shared MCP test clients can send authentication tokens over plaintext HTTP, and the C++ client disables certificate and hostname verification when TLS is enabled. Require authenticated, certificate- and hostname-verified HTTPS whenever a bearer token is configured, and apply the same invariant to both the shell helper and the C++ client.

Synchronize the test with probe start.
std::this_thread::sleep_for() does not prove that the asynchronous probe in tsdb_monitor_loop() has started. If get_tsdb_status() runs before the probe starts or after an early connection failure, the test can pass without exercising the intended overlap. Wait for a probe-start signal before timing get_tsdb_status().

When an affiliated module rejects the configuration—for example because its claimed hostgroups overlap a newly configured built-in topology—this early return silently leaves the old runtime servers installed. The Admin handler still sends OK for LOAD MYSQL SERVERS TO RUNTIME, and cluster callers continue treating the pull as successful and may persist the peer configuration, leaving MEMORY/disk inconsistent with runtime; the analogous PostgreSQL path has the same problem. Make these load functions return failure and require every Admin/cluster caller to propagate it before reporting or persisting success.

P2: This PR removes the only package-install verification for the fedora44-genai build, and the change is unrelated to the PR's stated goal (provider-neutral server discovery core). The removed step was the sole consumer of `test/infra/control/verify-package-install.bash` in this workflow, that script supports `fedora44` (it is in the script's `IMAGE_MAP`), and no workflow calls the reusable `gh-actions-reusable/verify-package-install.yml` to replace it.

P2: This PR removes the only package-install verification step in CI, and the PR description does not mention it. `verify-package-install.bash` fully supports centos10 (`IMAGE_MAP[centos10]=quay.io/centos/centos:stream10`), and the reusable `gh-actions-reusable/verify-package-install.yml` workflow is not referenced by any workflow, so after this change no package is smoke-tested for installability. The script catches missing runtime dependencies, file conflicts, and binary startup failures — exactly the class of problem the PR's own rollout notes (no AWS/CRT/s2n dynamic deps, ABI 9 rebuild) are meant to guard against. Restore the step or migrate it to the reusable workflow instead of deleting it.</violation>

The step caught missing runtime dependencies, file conflicts, binary startup failures, and missing plugin .so files for this distro/arch.

P2: This PR removes the only active package-install verification for the arm64 ubuntu24 package. The deleted step ran test/infra/control/verify-package-install.bash, which installs the built package on a clean distro container and catches missing runtime dependencies, file conflicts, binary startup failures, and missing plugin .so files. The reusable gh-actions-reusable/verify-package-install.yml exists but no workflow in this repo references it (rg 'uses:.*verify-package-install' finds no caller), and no other CI-package-*.yml runs the check, so nothing replaces this coverage. The PR description does not mention dropping package verification. If the intent is to migrate to the reusable workflow, wire it up from the caller; otherwise keep the inline step.

P3: `random_u30` was built from two 15-bit `fastrand()` draws (30 bits total), but `rand_fast()` returns 32 bits, so this now produces 47-bit values. The rejection loop `while (draw >= failover_acceptance)` with `failover_acceptance` ≈ 2^30 then accepts only ~1/131072 of draws, making `random_u30_in_20000()` loop ~131072 times on average per call instead of ~1. Distribution stays uniform, but the 30-bit intent (function name, `failover_range = 1ull << 30`) is lost and the test path gets a large constant slowdown. Mask the draw to 30 bits.</violation>

P3: The new wake test never exercises the fd-reuse scenario its message claims. `close_server_discovery_wake_pipe()` (lib/ProxySQL_Admin.cpp:3488-3503) sets `GloAdmin = nullptr` before `proxysql_wake_server_discovery_admin()` is called, and that function (lib/ProxySQL_Admin.cpp:3511-3517) returns at the `GloAdmin == nullptr` guard, so it can never write to the replacement pipe. The `read` on the fresh non-blocking pipe therefore always returns -1/EAGAIN and the `replacement_read`/`errno` terms of the assertion are tautological — they can never fail, so they add no coverage. The meaningful checks are the direct `pipefd == -1` and `GloAdmin == nullptr` state assertions; the pipe/fcntl/read machinery is dead. Drop the read machinery and keep the state assertions, or the test message should not claim the reuse scenario is verified.</violation>

P3: The new wake test never exercises the fd-reuse scenario its message claims. close_server_discovery_wake_pipe() (lib/ProxySQL_Admin.cpp:3488-3503) sets GloAdmin = nullptr before proxysql_wake_server_discovery_admin() is called, and that function (lib/ProxySQL_Admin.cpp:3511-3517) returns at the GloAdmin == nullptr guard, so it can never write to the replacement pipe. The read on the fresh non-blocking pipe therefore always returns -1/EAGAIN and the replacement_read/errno terms of the assertion are tautological — they can never fail, so they add no coverage. The meaningful checks are the direct pipefd == -1 and GloAdmin == nullptr state assertions; the pipe/fcntl/read machinery is dead. Drop the read machinery and keep the state assertions, or the test message should not claim the reuse scenario is verified.

- Around line 30-31: Add job-level permissions to the workflow job containing
“Check AI unit handoff contract,” setting contents access to read only. Keep the
existing script execution unchanged and ensure the job does not inherit broader
token permissions.
In `@src/SQLite3_Server.cpp`:
- Line 1889: Update random_u30() so both rand_fast() results are masked to 15
bits before combining, including the draw that is shifted left by 15; preserve
the existing unsigned combination and return behavior.
- Line 1932: Update the lag initialization around rand_fast() so the modulo
reduction is performed while the value remains uint32_t, then convert the
bounded result to int. Preserve the existing lag calculation and ensure lag_ms
cannot become negative due to implementation-defined narrowing.
In `@test/tap/tests/unit/genai_plugin_load_unit-t.cpp`:
- Line 97: Update the TAP plan in the test’s plan declaration from 96 to 94 so
it matches the 94 assertions emitted by the normal execution path.
In `@test/tap/tests/unit/plugin_servers_cluster_transport_unit-t.cpp`:
- Line 16: Update the unit test includes to add test_globals.h directly
alongside test_init.h, preserving the custom harness requirements for tests
under the unit directory.
- Around line 135-139: Update the test’s completion synchronization to use
pthread mutexes and the project’s pthread RAII guard pattern instead of
std::mutex and manual pthread_mutex_lock calls. In the relevant test setup
around done, done_mutex, done_cv, and the cluster mutexes, ensure both cluster
mutexes are acquired through RAII guards so std::thread construction failures
cannot leave them locked.
- Line 150: Update the completion waits around done_cv in the test so the first
wait result is retained and the return condition requires it to be false,
ensuring completion did not occur while both pull mutexes were held. Apply the
same requirement to the corresponding wait at the later location.

GitHub Actions documentation default GITHUB_TOKEN permissions pull_request workflow permissions omitted contents write
💡 Result:
In GitHub Actions, the GITHUB_TOKEN does not have write access to repository contents or pull requests by default [1][2]. Because of security updates implemented by GitHub, modern repositories (created after February 2, 2023) default to read-only permissions for the GITHUB_TOKEN [1]. If your workflow requires the ability to push code, modify files, or manage pull requests (e.g., creating a pull request, adding labels, or merging), you must explicitly elevate the permissions within your workflow YAML file [1][2]. You can do this at the workflow or job level using the permissions key [3][4][5]. For example, to grant write access to both repository contents and pull requests, you should configure your workflow as follows: permissions: contents: write pull-requests: write When you define the permissions key, any permission not explicitly listed is set to none [6]. Therefore, if your workflow also requires other default access (such as reading metadata), you should explicitly include those as well, or ensure the overall set of permissions meets your needs [6][2]. It is important to note that when a workflow is triggered by a pull request from a forked repository, the GITHUB_TOKEN is restricted to read-only access by default to prevent unauthorized write operations, regardless of the permissions configured in the workflow, unless specific enterprise or organization settings allow otherwise [3][7][6]. Additionally, if you need to trigger further workflow runs (such as on: push or on: pull_request) using changes made by your workflow, the GITHUB_TOKEN cannot be used for that purpose; you must use a personal access token or a GitHub App installation access token instead [8][1].

Mask both random draws before shifting.
rand_fast() returns a uint32_t, but random_u30() shifts the unmasked first draw by 15 bits. The result can exceed failover_acceptance, causing excessive rejection-loop iterations when TEST_AURORA_RANDOM is enabled. Mask both draws to 15 bits before combining them.

C++17 integral conversion unsigned integer to signed integer value not representable implementation-defined standard
💡 Result:
Under the C++17 standard, when converting an unsigned integer to a signed integer type, if the value cannot be represented in the destination type, the result is implementation-defined [1][2]. Specifically, the rule is defined in [conv.integral] (Integral conversions): "If the destination type is signed, the value is unchanged if it can be represented in the destination type; otherwise, the value is implementation-defined" [1][3]. This behavior was changed in C++20. Starting with C++20, the conversion is no longer implementation-defined; instead, it is defined as the unique value of the destination type that is congruent to the source integer modulo 2^N (where N is the number of bits in the destination type) [4][5]. In C++17, however, compilers remain free to define their own behavior for this case, although most modern implementations use the two's complement representation that matches the behavior adopted in C++20 [4][5].

Apply the modulo before narrowing to int.
rand_fast() returns uint32_t. In C++17, converting a value above INT_MAX to int is implementation-defined and can produce a negative value. The subsequent modulo and lag calculations can then produce a negative lag_ms. Reduce the unsigned value before conversion:
Proposed fix
- int lag_ms_i = rand_fast();
- lag_ms_i %= 2000;
+ int lag_ms_i = static_cast<int>(rand_fast() % 2000);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@src/SQLite3_Server.cpp` at line 1932, Update the lag initialization around
rand_fast() so the modulo reduction is performed while the value remains
uint32_t, then convert the bounded result to int. Preserve the existing lag
calculation and ensure lag_ms cannot become negative due to
implementation-defined narrowing.

Set the TAP plan to 94.
Line 97 declares 96 results, but the normal path emits 94 ok(...) results. TAP reports a plan mismatch and fails this test even when all assertions pass.

Include test_globals.h directly.
This unit test includes test_init.h but does not include test_globals.h. Add the required harness header directly.
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.

Use pthread synchronization with RAII guards.
Replace the std::mutex completion state and manual cluster mutex ownership with the project pthread synchronization pattern. Guard both cluster mutexes with RAII so a std::thread construction failure cannot leave either mutex locked.
As per coding guidelines, C++ files must use pthread mutexes for synchronization and RAII for resource management.

Reject completion before the v2 mutex is released.
Line 150 discards whether set_checksums completed while both pull mutexes were held. If no module pull is scheduled, the worker can complete in that first window and completed_after_v2 still becomes true. The test then passes without proving that the v2 pull occurred.
Retain the first wait result and require it to be false in the return condition.
Proposed fix
- (void)done_cv.wait_for(lock, std::chrono::milliseconds(200), [&] { return done; });
+ const bool completed_while_both_locks_held =
+ done_cv.wait_for(lock, std::chrono::milliseconds(200), [&] { return done; });
