Remove usage of deprecated variable storage_engine. It was deprecated in 5.5 but
it never issued a deprecation warning. Make it issue a warning in 10.5.1.
Replaced with default_storage_engine.
in HEAP btree indexes, the address of a record in memory is part of the
key. So, when inserting many identical keys, the actual btree
shape is defined by how and where records in memory are allocated.
records_in_range uses floats to estimate the size of the chunk of the
btree between min and max records, it depends on the btree shape and,
thus, is not portable either. As are optimizer decisions that are based
on records_in_range estimations, if the number happens to be close
to a tipping point.
as a fix, reduce the number of matching rows, so that even with
system-specific variations the optimizer would still pick the
expected plan.
Fixes heap.heap failure (range vs ALL) on ppc64
The reason was that a couple of variables that hold number of rows that was used to calculate buffers was uint and caused an overflow.
Fixed by changing variables that could hold number of rows from uint to ulong and also added a cast for this test.
include/heap.h:
Reorder to get better alignment. Changed variables that could hold number of rows from uint to ulong
mysql-test/suite/heap/heap.result:
Added test case
mysql-test/suite/heap/heap.test:
Added test case
mysql-test/suite/plugins/t/server_audit.test:
Added sleep as we want to have disconnect logged before we try a new connect
storage/heap/ha_heap.cc:
Changed variables that could hold number of rows from uint to ulong
Limit number of rows to 4G (as most of the variables that holds rows are ulong anyway)
reset records_changed when key_stat_version is changed to not cause increments for every row changed
storage/heap/ha_heap.h:
changed records_changed to ulong as this can get big
storage/heap/hp_create.c:
Changed variables that could hold number of rows from uint to ulong
Added cast (fixed the original bug)
storage/heap/hp_delete.c:
Changed variables that could hold number of rows from uint to ulong
storage/heap/hp_open.c:
Removed not needed cast
storage/heap/hp_write.c:
Changed variables that could hold number of rows from uint to ulong
support-files/compiler_warnings.supp:
Removed extra : from supression
mysql-test/suite/heap/heap.result:
Added test case
mysql-test/suite/heap/heap.test:
Added test case
storage/heap/hp_delete.c:
Fixed that we don't change order of keys for the current key when we delete them from the hash table.
Fixed that 'current_hash_ptr' is correct after heap_delete_key().
Don't "reset current_hash_ptr" on delete; This will improve time a lot for delete of rows when not all rows matches the search criteria.
mysql-test/suite/heap/heap.result:
Added test case for MDEV-436
mysql-test/suite/heap/heap.test:
Added test case for MDEV-436
storage/heap/hp_block.c:
Don't allocate a set of HP_PTRS when not needed. This saves us about 1024 bytes for most allocations.
storage/heap/hp_create.c:
Made the initial allocation of block sizes depending on min_records and max_records.
Moved test from main suite to the new suites.
Move tests from maria/t and maria/r to maria
mysql-test/mysql-test-run.pl:
Added support for the new suites
