mysys threads, mutexes, + read write locks and conditions. + This header file provides the necessary declarations + to use the mysys thread API with the performance schema instrumentation. + In some compilers (SunStudio), 'static inline' functions, when declared + but not used, are not optimized away (because they are unused) by default, + so that including a static inline function from a header file does + create unwanted dependencies, causing unresolved symbols at link time. + Other compilers, like gcc, optimize these dependencies by default. + + Since the instrumented APIs declared here are wrapper on top + of my_pthread / safemutex / etc APIs, + including mysql/psi/mysql_thread.h assumes that + the dependency on my_pthread and safemutex already exists. +*/ +/* + Note: there are several orthogonal dimensions here. + + Dimension 1: Instrumentation + HAVE_PSI_INTERFACE is defined when the instrumentation is compiled in. + This may happen both in debug or production builds. + + Dimension 2: Debug + SAFE_MUTEX is defined when debug is compiled in. + This may happen both with and without instrumentation. + + Dimension 3: Platform + Mutexes are implemented with one of: + - the
