Javier Jaramago Fernández	6c9e4c058b	Fix infinite loop for SSL connections - Closes #4314 ... If a peer closes the socket under certain timing conditions, e.g. during connection establishment, an infinite loop will take place if 'POLLHUP' and 'POLLIN' are set in the socket, and no data is present, just the final 'EOF'.	3 years ago
René Cannaò	8106ae5ee3	Merge branch 'v2.x' into v2.x_sha2pass_draft3	3 years ago
Rahim Kanji	c4dae72a45	Implemented the functionality to generate a coredump upon reaching a specific source file and line number. ... To enable coredump feature, specify the filename and line number in the coredump_filters table. Example: INSERT INTO coredump_filters (filename,line) VALUES ('mysql_data_stream.cpp', 498); LOAD COREDUMP TO RUNTIME; Note: * It is important to note that coredump filters cannot be persisted on disk and will always be empty when a new instance is created. * Filenames are case-sensitive * 'admin-coredump_generation_threshold', has been introduced to specify the maximum number of core files that can be generated. * 'admin-coredump_generation_interval_ms', has been implemented to define the time gap between the generation of core files.	3 years ago

René Cannaò	a34e680813	Different handling of POLLHUP in read_from_net() ... In MySQL_Data_Stream::read_from_net() we used to close the socket as soon as POLLHUP was received from poll(). We now call shut_soft() only if POLLIN is not set . This means that if we receive data (POLLIN) we process it temporarily ignoring POLLHUP . In this way we can intercept a COM_QUIT executed by the client before closing the socket	3 years ago
René Cannaò	16f952abb8	Fixed a harmless "Source and destination overlap in memcpy" ... Fixed a harmess overlap in memcpy() in queue_zero() when the queue itself is empty. If the queue is empty memcpy can be skipped.	3 years ago
