#define PFS_LOCK_ALLOCATED   0x02

State of an allocated record. Values of an allocated record are safe to read by a reader. A writer may modify some but not all properties of the record: only modifying values that can never cause the reader to crash is allowed.

#define PFS_LOCK_DIRTY   0x01

State of a dirty record. Values of a dirty record should not be read by a reader, as the record is currently being modified. Only one writer, the writer which owns the record, should modify the record content.

#define WAIT_STACK_BOTTOM   1

Maximum number dummy waits records. One dummy record is reserved for the parent stage / statement, at the bottom of the wait stack.

Definition at line 292 of file pfs_instr.h.

#define WAIT_STACK_LOGICAL_SIZE   5

Maximum number of nested waits. Some waits, such as:

• "wait/io/table/sql/handler"
• "wait/lock/table/sql/handler" are implemented by calling code in a storage engine, that can cause nested waits (file io, mutex, ...) Because of partitioned tables, a table io event (on the whole table) can contain a nested table io event (on a partition). Because of additional debug instrumentation, waiting on what looks like a "mutex" (safe_mutex, innodb sync0sync, ...) can cause nested waits to be recorded. For example, a wait on innodb mutexes can lead to:
• wait/sync/mutex/innobase/some_mutex
  • wait/sync/mutex/innobase/sync0sync
    • wait/sync/mutex/innobase/os0sync The max depth of the event stack must be sufficient for these low level details to be visible.

Definition at line 285 of file pfs_instr.h.

#define WAIT_STACK_SIZE   (WAIT_STACK_BOTTOM + WAIT_STACK_LOGICAL_SIZE)

Physical size of the waits stack
