Marko Mäkelä 4f8803c036 MDEV-34678 pthread_mutex_init() without pthread_mutex_destroy() ... When SUX_LOCK_GENERIC is defined, the srw_mutex, srw_lock, sux_lock are implemented based on pthread_mutex_t and pthread_cond_t. This is the only option for systems that lack a futex-like system call. In the SUX_LOCK_GENERIC mode, if pthread_mutex_init() is allocating some resources that need to be freed by pthread_mutex_destroy(), a memory leak could occur when we are repeatedly invoking pthread_mutex_init() without a pthread_mutex_destroy() in between. pthread_mutex_wrapper::initialized: A debug field to track whether pthread_mutex_init() has been invoked. This also helps find bugs like the one that was fixed by commit 1c8af2ae53 (MDEV-34422); one simply needs to add -DSUX_LOCK_GENERIC to the CMAKE_CXX_FLAGS to catch that particular bug on the initial server bootstrap. buf_block_init(), buf_page_init_for_read(): Invoke block_lock::init() because buf_page_t::init() will no longer do that. buf_page_t::init(): Instead of invoking lock.init(), assert that it has already been invoked (the lock is vacant). add_fts_index(), build_fts_hidden_table(): Explicitly invoke index_lock::init() in order to avoid a pthread_mutex_destroy() invocation on an uninitialized object. srw_lock_debug::destroy(): Invoke readers_lock.destroy(). trx_sys_t::create(): Invoke trx_rseg_t::init() on all rollback segments in order to guarantee a deterministic state for shutdown, even if InnoDB fails to start up. trx_rseg_array_init(), trx_temp_rseg_create(), trx_rseg_create(): Invoke trx_rseg_t::destroy() before trx_rseg_t::init() in order to balance pthread_mutex_init() and pthread_mutex_destroy() calls.		2024-08-14 07:54:15 +03:00
