Bug#26996 - Update of a Field in a Memory Table ends with wrong result
...
Using a MEMORY table BTREE index for scanning for updatable rows
could lead to an infinite loop.
Everytime a key was inserted into a btree index, the position
in the index scan was cleared. The search started from the
beginning and found the same key again.
Now we do not clear the position on key insert an more.

BUG#23443: user-defined variables can consume too much memory in the
...
server
The problem was that when memory was exhausted HEAP engine could crash
(GROUP BY uses HEAP TABLE). Alternatively, if SET was used, it could
report an error "You may only use constant expressions with SET" instead
of "Out of memory (Needed NNNNNN bytes)".
The solution is:
- pass MY_WME to (some) calls to my_malloc() to get correct message.
- fix heap_write() so that the first key is skipped during cleanup
on ENOMEM because it wasn't inserted and doesn't have to be
deleted.
No test case is provided because we can't test out-of-memory behaviour
in our current test framework.
