partitioned table
  
Post-pushbuild fix
  
Pushbuild detected a new need for lex initialization in
embedded server.

Fixed test for INSERT DELAYED in partitions_hash.test so that
it works with embedded server.


libmysqld/lib_sql.cc:
  Bug#31210 - INSERT DELAYED crashes server when used on
                  partitioned table
  Initialized lex for later use in open_table().

  Fixed test for embedded server.

            partitioned table

Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".

Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code
uses a new temporary instance of a lex. But it does still refer
to the previously active lex. The delayd insert thread does not
initialize its lex though...

Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.

BUG#18423: Added test case for this bug that was already fixed (was issue with hash partitions not showing all rows in BETWEEN range
Added test case for bug 18423


mysql-test/r/partition_hash.result:
  Added test case for bug 18423
mysql-test/t/partition_hash.test:
  Added test case for bug 18423

This bug was fixed through other patches.  This test case just shows 
that it is fixed.

fixed


mysql-test/r/partition_hash.result:
  results for newly added test.
mysql-test/t/partition_hash.test:
  test case for inserting a value into a hash that would generate a negative value
sql/sql_partition.cc:
  fields that generate a negative value would also generate a negative
  part_id which doesn't index into the m_file array to well.
