Rene Cannao	6b46b26931	chore: implement PR review feedback for release tier system ... - Makefile: normalized GIT_VERSION by stripping 'v' prefix before arithmetic. - Makefile: corrected .PHONY declaration for build_deps_debug_default. - Admin Handler: properly guarded TSDB commands to return error when disabled. - REST API: removed redundant nested guards inside tsdb_resource class. - Statistics: implemented rigorous input validation for set_variable. - Statistics: added return value checks and rollback logic for TSDB migrations. - Statistics: implemented bounded concurrency (batching) for backend probes. - FFTO: implemented cumulative buffer limit enforcement in MySQL and PgSQL. - FFTO: ensured initial packet capture in PgSQL_Session by early initialization. - FFTO: improved reassembly buffer compaction logic. - Headers: default-initialized ffto_bypassed to false. - Code cleanup: merged redundant PROXYSQLFFTO guards.	1 month ago
Rene Cannao	90462f6d5a	ffto: harden MySQL/PgSQL observer state handling and align tests/docs ... Address outstanding review findings for FFTO on v3.0-ff_inspect and tighten protocol-state correctness for both engines. MySQL FFTO - Restrict on_close() reporting to true in-flight states and always clear query tracking state after close. - Add explicit active-query cleanup helpers and invoke them on state transitions to IDLE. - Preserve accounting on mid-resultset server ERR packets by reporting current query in READING_COLUMNS/READING_ROWS before reset. - Keep prepared-statement lifecycle cleanup robust (pending prepare cleared on prepare completion paths). MySQL session integration - Extract duplicated FAST_FORWARD client FFTO feed logic into observe_ffto_client_packet() and reuse it from all call sites. PostgreSQL FFTO - Replace regex-based CommandComplete parsing with lightweight token parsing, including NUL/whitespace trimming and strict numeric validation. - Add queued tracking for pipelined extended-protocol executes so query text and response attribution stay aligned under Parse/Bind/Execute pipelining. - Distinguish finalize semantics (execute-finalize on CommandComplete vs sync-finalize on ReadyForQuery) and centralize finalize/activation helpers. - Add frontend Close ('C') handling to evict statement/portal mappings. - Harden client/server message parsing with additional length checks. - Extend affected-row command tag coverage to COPY and MERGE. TAP tests - Stabilize test plans for failure paths by replacing early returns with a fail-and-skip-remaining flow and shared cleanup labels. - Ensure both MySQL and PgSQL FFTO tests preserve planned assertion counts under setup/prepare/execute failures. Documentation - Align FFT0 design doc state/response descriptions with current implementation (ReadyForQuery handling, pipelined queueing, supported PG command tags). - Fix wording/typo issues in protocol section. Validation performed - make -C lib -j4 - make -C test/tap/tests test_ffto_mysql-t test_ffto_pgsql-t -j4 Runtime execution of the two TAP binaries remains environment-dependent (admin endpoint connectivity required).	2 months ago
