Rene Cannao 7e2f7828ae fix(mysqlx): make sync transactions atomic on execute() failure ... sync_disk_to_memory() and copy_to_runtime() in mysqlx_plugin.cpp now check every admindb.execute() return value. On BEGIN / DELETE / INSERT / COMMIT failure the code issues a best-effort ROLLBACK, logs via services->log_message, and skips the current table. Both functions return false if any table's transaction failed, true if every replace succeeded. coderabbitai flagged this on #5642, #5643, and #5644 (outside-diff because the file appears in each PR's surrounding context). Without the return checks, a failed INSERT landing between a successful DELETE and the unconditional COMMIT silently wiped routes / users / endpoints / backend_endpoints — the transaction wrap advertised atomicity it did not deliver. The fix restores that guarantee. The shared BEGIN/DELETE/INSERT/COMMIT body is now a local helper replace_table_atomically() that takes a ProxySQL_PluginServices* so it can log via the existing plugin log_message callback; the two callers reduce to four-line loops over their table lists. mysqlx_start passes ctx.services through; its return values remain advisory (log-and-continue on a false return), intentionally — plugins shouldn't block proxysql startup on one table's sync failure. Upgrading to fail-fast is a future decision. Testing: added test_insert_failure_rolls_back in test/tap/tests/unit/mysqlx_robustness_unit-t.cpp. It seeds a dst table with a CHECK (id %% 2 = 0) constraint plus pre-existing rows, points src at odd ids, runs the atomic replace, and asserts (a) the function returns false, (b) dst still holds its original rows, (c) the row sum matches the pre-transaction state. plan(35) -> plan(39). All 39 assertions pass. Out of scope: the Makefile link-line fix from 82fe27f4b still applies; no further ripple.		1 month ago
