The problem was that when a embedded linked version of mysqltest crashed there was no way to obtain a stack trace if no core file is available. Another problem is that the embedded version of libmysql was not behaving (crash) the same as the non-embedded with respect to sending commands to a explicitly closed connection. The solution is to generate a mysqltest's stack trace on crash and to enable "reconnect" if the connection handle was explicitly closed so the behavior matches the non-embedded one. client/CMakeLists.txt: Link mysys to mysqltest. client/Makefile.am: Link mysys to mysqltest. client/mysqltest.c: Add fatal signal handling with backtracing for Unix and Windows. configure.in: Add check for weak symbols support and remove a spurious word. include/Makefile.am: Add new header with prototype for stack tracing functions. include/my_stacktrace.h: Add new header with prototype for stack tracing functions. libmysqld/CMakeLists.txt: stack tracing is now part of mysys. libmysqld/Makefile.am: stack tracing is now part of mysys. libmysqld/lib_sql.cc: Re-connect if connection was explicitly closed. This is done to match the behavior of the non-embeded libmysql. mysql-test/t/sql_low_priority_updates_func.test: Test expects parallelism between queries that cannot be guaranteed under embedded. mysys/CMakeLists.txt: Add stacktrace to mysys. mysys/Makefile.am: Add stacktrace to mysys. mysys/stacktrace.c: Move stacktrace to mysys and add weak symbol for the C++ name de-mangling function so that it can later be overridden in C++ code. Also add my_ prefix to exported functions. sql/CMakeLists.txt: stacktrace was moved to mysys. sql/Makefile.am: stacktrace was moved to mysys. sql/mysqld.cc: Add my_ prefix to mysys functions.
