Fixed bugs:
#16814: SHOW INNODB STATUS format error in LATEST FOREIGN KEY ERROR section
dict_foreign_key_error_report(): Always print a newline after invoking
dict_print_info_on_foreign_key_in_create_format().
#16827: Better InnoDB error message if ibdata files omitted from my.cnf.
#17126: CHECK TABLE on InnoDB causes a short hang during check of adaptive hash.
CHECK TABLE blocking other queries, by releasing the btr_search_latch
periodically during the adaptive hash table validation.
#17405: Valgrind: conditional jump or move depends on uninitialised valuesw.
buf_block_init(): Reset magic_n, buf_fix_count, and io_fix to avoid testing
uninitialised variables.
#18077: InnoDB uses full explicit table locks in stored FUNCTION.
#18238: When locks exhaust the buffer pool, InnoDB does not roll back the trx.
Check in pessimistic insert and update if the buffer pool is exhausted by locks.
#18252: Disk space leaks in updates of InnoDB BLOB rows.
btr_cur_pessimistic_update(): Invoke rec_get_offset() after rec_set_field_extern_bits().
btr_store_big_rec_extern_fields(): Note that offsets will no longer be valid
after calling this function.
#18283: When InnoDB returns error 'lock table full', MySQL can write to binlog too much.
#18384: InnoDB memory leak on duplicate key errors if row has many columns.
row_ins_duplicate_error_in_clust(): Call mem_heap_free(heap) at func_exit if needed.
#18350: Use consistent read in CREATE ... SELECT .. if innodb_locks_unsafe_for_binlog is used.
A table with an on insert trigger was reported as crashed when the insert
was processed with bulk insert mode on (handler::start_bulk_insert).
The trigger was also selecting from the same table, and that caused
the "crash".
The same problem was present when an insert statement, which was processed
in bulk mode, also used a stored function that was reading the same table.
This fix disables bulk inserts if a statement uses functions or invokes
triggers. Implementing more granular checks will require much more code and
therefore can hardly be done in 5.0
VIEWs, Prepared statement": we didn't mark the nested views
as 'prelockng placeholders' when building the prelocking list.
This resulted in these views being processed (merged, materialized)
before they are actually used.
in older version.
The problem is that TRN-files created in "old" versions contain
junk in trigger_table field, which is not acceptable in "new" versions.
If the WHERE condition of a query contained an ORed FALSE term
then the set of tables whose rows cannot serve for null complements
in outer joins was determined incorrectly. It resulted in blocking
possible conversions of outer joins into joins for such queries.
tables corrupt triggers".
It turned out that we also have relied at certain places that
(new_table != table_name) were always true on Windows and for transactional
tables. Since our fix for the bug brakes this assumption we have to add new
flag to pass this information around.
This code needs to be refactored but I dare not to do this in 5.0.
triggers".
Applying ALTER/OPTIMIZE/REPAIR TABLE statements to transactional table or to
table of any type on Windows caused disappearance of its triggers.
Bug was introduced in 5.0.19 by my fix for bug #13525 "Rename table does not
keep info of triggers" (see comment for sql_table.cc for more info).
