Subject: [PATCH 02/10] BUG#26080 - Memory Storage engine not working properly

Extending varchar column length with ALTER TABLE may result in unusable
memory table.

The problem is that we use fast ALTER TABLE in this case, which is not
supported by now.

This is fixed by refusing fast ALTER TABLE when extending varchar column.
In other words force copy of a table during ALTER TABLE.

Affects MEMORY tables in 5.1 only.

  A test case for BUG#26080.

  A test case for BUG#26080.
storage/heap/ha_heap.cc:
  For MEMORY, if varchar column extended, it should return incompatible for
  now. In other words force copy of a table during alter table.

Subject: [PATCH 03/10] BUG#26238 - inserted delayed always inserts 0 for BIT
 columns

INSERT DELAYED inserts garbage for BIT columns.

When delayed thread clones TABLE object, it didn't adjusted bit_ptr
to newly created record (though it correctly adjusts ptr and null_ptr).

This is fixed by correctly adjusting bit_ptr when performing a clone.
With this fix BIT values are stored correctly by INSERT DELAYED.

Subject: [PATCH 04/10] Bug#26464 - insert delayed + update + merge =
 corruption

Using INSERT DELAYED on MERGE tables could lead to table
corruptions.

The manual lists a couple of storage engines, which can be
used with INSERT DELAYED. MERGE is not in this list.

The attempt to try it anyway has not been rejected yet.
This bug was not detected earlier as it can work under
special circumstances. Most notable is low concurrency.

To be safe, this patch rejects any attempt to use INSERT
DELAYED on MERGE tables.


mysql-test/r/merge.result:
  Bug#26464 - insert delayed + update + merge = corruption
  Added test result.
mysql-test/t/merge.test:
  Bug#26464 - insert delayed + update + merge = corruption
  Added test.
sql/ha_myisammrg.h:
  Bug#26464 - insert delayed + update + merge = corruption
  Removed HA_CAN_INSERT_DELAYED flag from table_flags().
  The insert delayed thread upgrades the lock from the first
  entry in MYSQL_LOCK::locks only. Hence it is incapable to
  handle MERGE tables, which have as many entries in this
  array as they have MyISAM sub-tables.

Subject: [PATCH 05/10] Bug#25673 - spatial index corruption, error 126        
   incorrect key file for table

In certain cases it could happen that deleting a row could
corrupt an RTREE index.

According to Guttman's algorithm, page underflow is handled
by storing the page in a list for later re-insertion. The
keys from the stored pages have to be inserted into the
remaining pages of the same level of the tree. Hence the
level number is stored in the re-insertion list together
with the page.

In the MySQL RTree implementation the level counts from zero
at the root page, increasing numbers for levels down the tree.

If during re-insertion of the keys the tree height grows, all
level numbers become invalid. The remaining keys will be
inserted at the wrong level.

The fix is to increment the level numbers stored in the
reinsert list after a split of the root block during reinsertion.


myisam/rt_index.c:
  Bug#25673 - spatial index corruption, error 126
              incorrect key file for table
  Added a loop in rtree_delete() to increment the level numbers
  stored in the reinsert list after a split of the root block
  during reinsertion.
  Added comments and DBUG statements.

Subject: [PATCH 09/10] BUG#26881 - Large MERGE tables report incorrect
 specification when no             differences in tables Certain merge tables
 were wrongly reported as having incorrect definition: - Some fields that are
 1 byte long (e.g. TINYINT, CHAR(1)), might   be internally casted (in certain
 cases) to a different type on a   storage engine layer. (affects 4.1 and up)
 - If tables in a merge (and a MERGE table itself) had short VARCHAR column
 (less   than 4 bytes) and at least one (but not all) tables were ALTER'ed
 (even to an   identical table: ALTER TABLE xxx ENGINE=yyy), table definitions
 went ouf of   sync. (affects 4.1 only)

This is fixed by relaxing a check for underlying conformance and setting
field type to FIELD_TYPE_STRING in case varchar is shorter than 4
when a table is created.


myisam/mi_create.c:
  Added a comment.
mysql-test/r/merge.result:
  A test case for bug#26881.
mysql-test/t/merge.test:
  A test case for bug#26881.
sql/ha_myisam.cc:
  Relaxed some checks performed by check_definition():
  As comparing of fulltext keys (and key segments) is not yet implemented,
  only return an error in case one of keys is fulltext and other is not.
  Otherwise, if both keys are fulltext, accept them as is.

  As comparing of spatial keys (and key segments) is not yet implemented,
  only return an error in case one of keys is spatial and other is not.
  Otherwise, if both keys are spatial, accept them as is.

  A workaround to handle situation when field is casted from FIELD_SKIP_ZERO
  to FIELD_NORMAL. This could happen only in case field length is 1 and row
  format is fixed.
sql/sql_parse.cc:
  When a table that has varchar field shorter than 4 is created, field type is
  set to FIELD_TYPE_VAR_STRING. Later, when a table is modified using alter
  table, field type is changed to FIELD_TYPE_STRING (see Field_string::type).
  That means HA_OPTION_PACK_RECORD flag might be lost and thus null_bit might
  be shifted by alter table, in other words alter table doesn't create 100%
  equal table definition.

  This is usually not a problem, since when a table is created/altered,
  definition on a storage engine layer is based on one that is passed from
  sql layer. But it is a problem for merge engine - null_bit is shifted when
  a table (merge or underlying) is altered.

  Set field type to FIELD_TYPE_STRING in case FIELD_TYPE_VAR_STRING is shorter
  than 4 when a table is created as it is done in Field::type.
