#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.

◆ PFS_LOCK_DIRTY

#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.

◆ PFS_LOCK_FREE

#define PFS_LOCK_FREE   0x00

State of a free record.

Values of a free record should not be read by a reader. Writers can concurrently attempt to allocate a free record.

◆ WAIT_STACK_BOTTOM

#define WAIT_STACK_BOTTOM   1

Maximum number dummy waits records.

One dummy record is reserved for the parent stage / statement / transaction, at the bottom of the wait stack.

◆ WAIT_STACK_LOGICAL_SIZE

#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 I/O, mutex, ...) Because of partitioned tables, a table I/O event (on the whole table) can contain a nested table I/O 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.

◆ WAIT_STACK_SIZE

#define WAIT_STACK_SIZE   (WAIT_STACK_BOTTOM + WAIT_STACK_LOGICAL_SIZE)

Physical size of the waits stack.

◆ reset_source_file_pointers()

void reset_source_file_pointers ( )

Clear the source file pointers from all waits, stages, statements and transaction events.

Clear source file pointers for all statements, stages, waits and transactions.

This function is called whenever a plugin or component is unloaded.

The Performance Schema stores the source file and line number for wait, stage, statement, transaction and metadata lock events. The source file string pointer is taken from the FILE macro. Source file pointers that reference files within a shared library become invalid when the shared library is unloaded, therefore all source file pointers are set to NULL whenever a plugin or component is unloaded.
