Rahim Kanji	285fb1b4e1	Add PostgreSQL dialect support: dollar-quoted strings, identifier quoting, and dialect-specific comment rules This change introduces PostgreSQL-aware tokenization by adding support for dollar-quoted strings, PostgreSQL’s double-quoted identifiers, and its comment rules. The tokenizer now correctly parses $$…$$ and $tag$…$tag$, treats " as an identifier delimiter in PostgreSQL, disables MySQL-only # comments, and accepts -- as a comment starter without requiring a trailing space. All new behavior is fully isolated behind the dialect flag to avoid impacting MySQL parsing. Add PostgreSQL dollar-quoted strings * New parser state: st_dollar_quote_string. * Recognizes $$ … $$ and $tag$ … $tag$ sequences. * Tracks opening tag and searches for matching terminator. * Normalizes entire literal to ?. * Integrated into get_next_st() and stage_1_parsing().	5 months ago

Rene Cannao	b1a1930e1c	Add working TAP test for TCP keepalive warnings (issue #5212 ) - Implement get_matching_lines_from_filename() with efficient queue-based processing - Use standard C++ regex instead of RE2 for reliable pattern matching - Add filename-based function to avoid stream sharing conflicts - Remove problematic stream-based function with max_lines parameter - Fix regex pattern to match actual log warning format - Add comprehensive debugging output (disabled with #if 0) - Test both MySQL and PostgreSQL TCP keepalive warnings - Search only last 10 lines for efficiency and relevance The test now correctly verifies that TCP keepalive warnings are logged when mysql-use_tcp_keepalive or pgsql-use_tcp_keepalive is set to false.	5 months ago
Rene Cannao	e54e3c8df3	Add TAP test for TCP keepalive warnings with line-limited get_matching_lines() - Add TAP test mysql-reg_test_5212_tcp_keepalive_warnings-t.cpp to verify TCP keepalive warnings - Add overload of get_matching_lines() with max_lines parameter to scan only last N lines - Current implementation reads entire file into memory (inefficient) - needs optimization - Test reports finding 4 MySQL warnings in 50 lines (impossible) - indicates bug - Add debugging output to show lines read vs lines examined WIP: get_matching_lines() optimization needed using queue instead of vector WIP: Test logic debugging needed for impossible warning counts Resolves: #5212	5 months ago
Rene Cannao	6ed82ef8cb	Fix crash in TCP keepalive warnings for issue #5212 - Fix crash by using get_variable_int() instead of get_variable_string() for boolean use_tcp_keepalive variable - use_tcp_keepalive is a boolean variable, not a string, so get_variable_int() returns 0/1 instead of a string - Fix syntax errors by removing duplicate code and fixing brace structure - Add comprehensive Doxygen documentation for both MySQL and PostgreSQL warnings Resolves assertion failure: "Not existing variable: use_tcp_keepalive" Resolves: #5212	5 months ago

Rene Cannao	44aa606caa	Implement fast forward grace close feature to prevent data loss Problem: In fast forward mode, ProxySQL forwards packets directly from client to backend without buffering them. If the backend connection closes unexpectedly (e.g., due to server crash, network failure, or other issues), ProxySQL immediately closes the client session. This can result in data loss because the client may have sent additional data that hasn't been fully transmitted yet, as ProxySQL does not wait for the output buffers to drain. Solution: Implement a configurable grace period for session closure in fast forward mode. When the backend closes unexpectedly, instead of closing the session immediately, ProxySQL waits for a configurable timeout (fast_forward_grace_close_ms, default 5000ms) to allow any pending client output data to be sent. During this grace period: - If the client output buffers become empty, the session closes gracefully. - If the timeout expires, the session closes anyway to prevent indefinite hanging. Changes: - Added global variable mysql_thread___fast_forward_grace_close_ms (0-3600000ms) - Added session flags: backend_closed_in_fast_forward, fast_forward_grace_start_time - Added data stream flag: defer_close_due_to_fast_forward - Modified MySQL_Data_Stream::read_from_net() to detect backend EOF and initiate grace close if client buffers are not empty - Modified MySQL_Session::handler() FAST_FORWARD case to implement grace close logic with timeout and buffer checks - Added extensive inline documentation explaining the feature and its mechanics This prevents data loss in fast forward scenarios while maintaining bounded session lifetime.	5 months ago
