Rene Cannao	d7c4a1a94c	fix(tests): resolve flaky failures in pgsql-copy_from_stdin_session_parameter-t and test_dns_cache-t ... 1. pgsql-copy_from_stdin_session_parameter-t: race condition in log file reading The test's check_logs_for_command() performed a single stream-based read via get_matching_lines() to find the "Switching back to Normal mode" log line. When ProxySQL hadn't flushed the log entry yet (observed window as tight as ~23 microseconds between PQgetResult returning and the check), the read would miss the line, causing a false test failure. The log line was always present in the final file, confirming this is a timing issue. Fix: Replace the single-shot read with a retry loop (up to 10 attempts, 10ms each = 100ms total). If all stream-based retries fail, fall back to get_matching_lines_from_filename() which opens a fresh file handle, avoiding any stream position issues entirely. Add a global g_proxysql_log_path to support the filename-based fallback. 2. test_dns_cache-t: spurious dns_cache_queried counter increment in Step 9 Step 9 disables the DNS cache refresh interval (set to 0) and expects dns_cache_queried to remain unchanged (equal_to). However, INVALID_DOMAIN was still in mysql_servers from Step 8, so when "DO 1" queries were routed through hostgroup 999, the connection routing layer called MySQL_Monitor::dns_lookup() -> DNS_Cache::lookup(), incrementing the counter by exactly 1 regardless of the refresh interval setting. Fix: Before the measurement window in Step 9, replace INVALID_DOMAIN with 0.0.0.0 in mysql_servers. Since 0.0.0.0 is a valid IP address, dns_lookup() returns immediately without consulting the DNS cache (early return at MySQL_Monitor.cpp:6675), so the counter stays unchanged as expected. Both fixes verified: each test passes in isolation against legacy infra.	1 month ago

Javier Jaramago Fernández	ef3360f102	Several enhancements for TAP tests compilation ... - Split 'libtap' into different binaries. This allows for the reuse of 'TAP' utilities that make use of MySQL or other third party library versions. Each of these tests that require special library versions that aren't the common ones embedded into the dynamic library 'libtap.so' should be compiled defining special helper targets, in the 'tests' folder Makefile itself. These helper targets with specify the linking of the required version of the library for the test. Each MySQL client version supported by the 'tap' tests that breaks headers compatibility should be compiled into a different object file, following the previous described procedure. - Add MySQL 8.4.0 client library as a new TAP test dependency. - Multiple compilation fixes consequence of the introduced change to 'libtap.a'. - Added as ProxySQL dependency the forward declaration header for 'nlohmann::json'. This header is the proper way of including the library is headers which are sensible of being included in multiples files. This speeds compilation times of each TAP test. - Removed 'std::regex' dependency from 'utils.cpp', and replaced by project dependency 're2'. Library 'std::regex' should not be used in any place that introduces it as a dependency for later objects, it's heavy, slow, and should be avoided in general.	2 years ago
