Rene Cannao	573a3fd256	Address AI code review feedback on PgSQL FFTO tests (#5517 ) Fixes from Copilot and CodeRabbit reviews on PR #5526: 1. Buffer overflow risk in mysql_real_escape_string: All 7 PgSQL test files used fixed 256-byte buffers for escaped credentials. Changed to VLAs sized from strlen() (2*len+1), matching the safe pattern used in the existing test_ffto_pgsql-t.cpp. 2. NULL dereference in polling loops: mysql_store_result() can return NULL, and calling mysql_fetch_row(NULL) is undefined behavior. Added NULL checks in all verify_pg_digest(), poll_pg_digest_count(), verify_digest(), and poll_digest_count() polling loops across both PgSQL and MySQL test files. In loop contexts, uses continue; in non-loop contexts, uses conditional fetch (res ? fetch(res) : NULL). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	3 months ago
Rene Cannao	fd7ac876e2	Fix build issues in PgSQL FFTO E2E tests (#5517 ) Two build issues fixed across all 7 PgSQL FFTO test files: 1. PROTOCOL_VERSION macro conflict: pg_lite_client.h defines PROTOCOL_VERSION as a static const int, but mariadb_version.h (included via mysql.h) defines it as a preprocessor macro (#define PROTOCOL_VERSION 10). Fixed by including pg_lite_client.h before mysql.h in the two tests that use it. 2. MYSQL_QUERY in void function: The clear_pg_stats() helper is a void function, but MYSQL_QUERY macro expands to "return EXIT_FAILURE" on error, which doesn't compile in a void context. Fixed by using mysql_query() directly instead of the MYSQL_QUERY macro in all clear_pg_stats() definitions. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	3 months ago

Address AI code review feedback on PgSQL FFTO tests (#5517 )

Fixes from Copilot and CodeRabbit reviews on PR #5526:

1. Buffer overflow risk in mysql_real_escape_string: All 7 PgSQL test
   files used fixed 256-byte buffers for escaped credentials. Changed
   to VLAs sized from strlen() (2*len+1), matching the safe pattern
   used in the existing test_ffto_pgsql-t.cpp.

2. NULL dereference in polling loops: mysql_store_result() can return
   NULL, and calling mysql_fetch_row(NULL) is undefined behavior.
   Added NULL checks in all verify_pg_digest(), poll_pg_digest_count(),
   verify_digest(), and poll_digest_count() polling loops across both
   PgSQL and MySQL test files. In loop contexts, uses continue; in
   non-loop contexts, uses conditional fetch (res ? fetch(res) : NULL).

Fix build issues in PgSQL FFTO E2E tests (#5517 )

Two build issues fixed across all 7 PgSQL FFTO test files:

1. PROTOCOL_VERSION macro conflict: pg_lite_client.h defines
   PROTOCOL_VERSION as a static const int, but mariadb_version.h
   (included via mysql.h) defines it as a preprocessor macro (#define
   PROTOCOL_VERSION 10). Fixed by including pg_lite_client.h before
   mysql.h in the two tests that use it.

2. MYSQL_QUERY in void function: The clear_pg_stats() helper is a
   void function, but MYSQL_QUERY macro expands to
   "return EXIT_FAILURE" on error, which doesn't compile in a void
   context. Fixed by using mysql_query() directly instead of the
   MYSQL_QUERY macro in all clear_pg_stats() definitions.

FFTO E2E TAP test: concurrent PostgreSQL sessions (#5517 )

Add test_ffto_pgsql_concurrent-t.cpp covering FFTO behavior under
concurrent PgSQL load with 10 threads. Part of issue #5517.

Test scenarios (13 TAP assertions):
1. Table setup with 100 seed rows via generate_series.
2. 10 pthreads, each with own PGconn (fast_forward=1). Each thread
   executes 50 SELECTs + 50 INSERTs with per-thread ID ranges.
3. Aggregate stats: SUM(count_star) >= 1000, SUM(rows_affected) >= 500.

Thread safety: std::mutex serializes TAP ok() calls. Each thread gets
its own PGconn -> PgSQL_Session -> PgSQLFFTO instance. Connection
retries (3 attempts) handle transient load.
