Marko Mäkelä 6852a32642 Bug#13340047 LATCHING ORDER VIOLATION IN IBUF_SET_ENTRY_COUNTER() ... ibuf_insert_low(), the only caller of ibuf_set_entry_counter(), will have latched an insert buffer bitmap page in bitmap_mtr before invoking ibuf_set_entry_counter(). The latching order forbids any further pages to be latched. ibuf_set_entry_counter(): Renamed to ibuf_get_entry_counter(), simplified the code and added comments. Added the following symbols for predefined field numbers in change buffer records: #define IBUF_REC_FIELD_SPACE 0 /*!< in the pre-4.1 format, the page number. later, the space_id */ #define IBUF_REC_FIELD_MARKER 1 /*!< starting with 4.1, a marker consisting of 1 byte that is 0 */ #define IBUF_REC_FIELD_PAGE 2 /*!< starting with 4.1, the page number */ #define IBUF_REC_FIELD_METADATA 3 /* the metadata field */ #define IBUF_REC_FIELD_USER 4 /* first user field */ rb:802 approved by Sunny Bains		2011-11-07 09:28:02 +02:00
