rem0rec.c:
rec_init_offsets(): Make the function comment more accurate.
rem0rec.ic:
rec_get_nth_field(): Return pointer to the field, even to NULL fields.
rec_set_nth_field(): Make more accurate debug assertions.
Fix InnoDB critical bug #7496; we scan the InnoDB data dictionary also at a normal mysqld startup, and create the spaces, so that we know the mapping space id -> .ibd file name; fix an infinite loop if DISCARD TABLESPACE coincides with INSERT or some other table operation; fix a potential crash if DISCARD TABLESPACE coincides with a cascaded FOREIGN KEY operation in the same table; do not allow DISCARD TABLESPACE of a referenced table if FOREIGN_KEY_CHECKS=1

Print progress of background rollback of transactions with more than 1000 undo log entries
srv0start.c, trx0roll.c, log0recv.c, trx0roll.h:
Cleanup background rollback code in crash recovery; do not flush all modified pages from the buffer pool after a crash recovery: this makes mysqld accesible for users more quickly
Do not use short int in rem0rec.ic, since its size is not fixed in ANSI C; improve comments of the relative offset field in a record; use mach_read_from_2() to read the relative offset field to save CPU time, if the compiler does not optimize a more complex access function
transactional table locks to tables mentioned in the query. These locks
are released at the end of the transaction automatically.
This is fix for bugs #5655, #5998 and issue #3762.
Remove parameter from call to btr_search_validate().
buf0buf.c:
Initialize member "index" of buf_block_t.
buf0buf.h:
Add member "index" to buf_block_t.
btr0sea.h:
Remove parameter of btr_search_validate()
btr0sea.c:
Make use of the added member "index" of buf_block_t.
Sergey Petrunia's ROR code fails to tell handlers that they should retrieve the primary key columns; let InnoDB ALWAYS retrieve them, to fix many bugs and potential bugs
Fix bug #6817 and bug #6827 : do not crash the server if the buffer pool becomes filled by the locks of ONE huge transaction, return error 1206 instead; do not crash the server, but return error if we cannot allocate memory for the buffer pool at a mysqld startup
