CONJ-398 Improve deadlock debugging capabilities
MariaDB has now 2 new options to permit identifying deadlock : New options:
|includeInnodbStatusInDeadlockExceptions||add "SHOW ENGINE INNODB STATUS" result to exception trace when having a deadlock exception.|
|includeThreadDumpInDeadlockExceptions||add thread dump to exception trace when having a deadlock exception.|
CONJ-639 the option "enabledSslProtocolSuites" now include TLSv1.2 by default
previous default value was "TLSv1, TLSv1.1", disabling TLSv1.2 by default, due to a corrected issue (MDEV-12190) with servers using YaSSL - not openSSL. Server error was . Now, the default value is "TLSv1, TLSv1.1, TLSv1.2". So TLSv1.2 can be use directly. Connecting MySQL community server use YaSSL without correction, and connection might result in SSLException: "Unsupported record version Unknown-0.0".
CONJ-642 disable the option "useBulkStmts" by default
Using useBulkStmts permit faster batch, but cause one major issue : Batch return -1 = SUCCESS_NO_INFO
Different option use this information for optimistic update, and cannot confirm if update succeed or not. This option still makes sense, since for big batch is way more faster, but will not be activated by default.
