An attempt to open file with name '????????.frm'
can produce different errors:
- ER_NO_SUCH_TABLE on Unix
- ER_FILE_NOT_FOUND on Windows
because QUESTION MARK has special meaning on Windows.
Make sure that any of these two errors happens.
Problem: Temporary buffer which is used for quoting and escaping
was initialized to character set utf8, and thus didn't allow
to store data in other character sets.
Fix: changing character set of the buffer to be able to
store any arbitrary sequence of bytes.
of its arguments was evaluated to NULL, while the predicate
LOCATE(str,NULL) IS NULL erroneously was evaluated to FALSE.
This happened because the Item_func_locate::fix_length_and_dec
method by mistake set the value of the maybe_null flag for
the function item to 0. In consequence of this the function
was considered as the one that could not ever return NULL.
Problem: crash on attempt to open a table
having "#mysql50#" prefix in db or table name.
Fix: This prefix is reserved for "mysql_upgrade"
to access 5.0 tables whose file names are not encoded
according to "5.1 tablename to filename encoded".
Don't try open tables whose db name or table name
has this prefix.
was erroneously converted to double, while the result of
ROUND(<decimal expr>, <int literal>) was preserved as decimal.
As a result of such a conversion the value of ROUND(D,A) could
differ from the value of ROUND(D,val(A)) if D was a decimal expression.
Now the result of the ROUND function is never converted to
double if the first argument is decimal.
Bug was updated on May 30th by Tomas to say that hasn't been seen in PB
since global dict cache rewrite. This test should probably be enabled then.

===================================================================
This is somewhat related to BUG#26675 (ndb_connectstring not reported
in show global variables)
Index: ndb-work/mysql-test/r/ndb_basic.result
===================================================================
the reported test failure is fixed by the patch to 28333,
but there's a bit more to fix in the test itself - to
drop tables created in this test at the test's beginning.
On many architectures, e.g. 68000, x86, the double registers have higher precision
than the IEEE standard prescribes. When compiled with flags -O and higher, some double's
go into registers and therefore have higher precision. In one test case the cost
information of the best and second-best key were close enough to be influenced by this
effect, causing a failed test in distribution builds.
Fixed by removing some rows from the table in question so that cost information is not
influenced by decimals beyond standard definition of double.
- fixed wrong test case for bug 20903
- closed the dangling connections in trigger.test
- GET_LOCK() and RELEASE_LOCK() now produce more detailed log
- fixed an omission in GET_LOCK() : assign the thread_id when
acquiring the lock.
