762c7ca462 Fix for bug#56679: gis.test: valgrind error
Item_func_spatial_collection::fix_length_and_dec()
changed to use argument's print() method to print
the ER_ILLEGAL_VALUE_FOR_TYPE error.


mysql-test/r/gis.result:
  Fix for bug#56679: gis.test: valgrind error
    - test result adjusted.

  Fix for bug#56679: gis.test: valgrind error
    - use argument's print() method instead of improper val_str()
  call in the Item_func_spatial_collection::fix_length_and_dec(), as
  it's applicable only for constant items.

9a4a7cf184 Bug#55531 crash with conversions of geometry types / strings
Convertion from a floating point number to a string caused a
crash.

During rare circumstances a String object could crash when
it was requested to allocate new memory.
A crash could occcur in Field_double::val_str() because of
a pointer referencing memory inside a String object which was
of unknown size.
And finally, the geometric collection should not accept
arguments which are non geometric.


mysql-test/r/gis.result:
  * Test cases change because we intercept the error behind the
  previous crashes much earlier.
sql/field.cc:
  * It makes no sense to impose a lower limit on the length
  and not setting a upper limit will cause crashes later.
sql/item_geofunc.h:
  * Disallow for binding with field- and item types which
  differ from MYSQL_TYPE_GEOMETRY types.

4f4d03a416 Bug#51070: Query with a NOT IN subquery predicate returns a wrong result set
The EXISTS transformation has additional switches to catch the known corner
cases that appear when transforming an IN predicate into EXISTS. Guarded
conditions are used which are deactivated when a NULL value is seen in the
outer expression's row. When the inner query block supplies NULL values,
however, they are filtered out because no distinction is made between the
guarded conditions; guarded NOT x IS NULL conditions in the HAVING clause that
filter out NULL values cannot be de-activated in isolation from those that
match values or from the outer expression or NULL's.

The above problem is handled by making the guarded conditions remember whether
they have rejected a NULL value or not, and index access methods are taking
this into account as well. 

The bug consisted of 

1) Not resetting the property for every nested loop iteration on the inner
   query's result.

2) Not propagating the NULL result properly from inner query to IN optimizer.

3) A hack that may or may not have been needed at some point. According to a
   comment it was aimed to fix #2 by returning NULL when FALSE was actually
   the result. This caused failures when #2 was properly fixed. The hack is
   now removed.

The fix resolves all three points.

d6f6db6f4c Fixed bug #55421 - Protocol::end_statement(): Assertion `0' on
multi-table UPDATE IGNORE.
The problem was that if there was an active SELECT statement
during trigger execution, an error risen during the execution
may cause a crash. The fix is to temporary reset LEX::current_select
before trigger execution and restore it afterwards. This way
errors risen during the trigger execution are processed as
if there was no active SELECT.

mysql-test/r/trigger_notembedded.result:
  added test case result for bug #55421.
mysql-test/t/trigger_notembedded.test:
  added test case for bug #55421.
sql/sql_trigger.cc:

  and restore its original value after execution is finished.
  This is neccessery in order to set error status in 
  diagnostic_area in case of trigger execution failure.

446cc653c0 Bug#54543: update ignore with incorrect subquery leads to assertion failure:
inited==INDEX

When an error occurs while sending the data in a temporary table there was no
cleanup performed. This caused a failed assertion in the case when different
access methods were used for populating the table vs. retrieving the data from
the table if IGNORE was specified and sql_safe_updates = 0. In this case
execution continues, but the handler expects to continue with the access
method used for row retrieval.

Fixed by doing the cleanup even if errors occur.

0f3d4b2f76 Fixed bug that 'maria_read_log -a' didn't set max_trid when reparing tables.
Fixed bug in Aria when replacing short keys with long keys and a key tree both overflow and underflow at same time.
Fixed several bugs when generating recovery logs when using RGQ with replacing long keys with short keys and vice versa.
Lots of new DBUG_ASSERT()'s
Added more information to recovery log to make it easier to know from where log entry orginated.
Introduced MARIA_PAGE->org_size that tells what the size of the page was in last log entry. This allows us to find out if all key changes for index page was logged.
Small code cleanups:
- Introduced _ma_log_key_changes() to log crc of key page changes
- Added share->max_index_block_size as max size of data one can put in key block (block_size - KEYPAGE_CHECKSUM_SIZE)
  This will later simplify adding a directory to index pages.
- Write page number instead of page postition to DBUG log



mysql-test/lib/v1/mysql-test-run.pl:
  Use --general-log instead of --log to disable warning when using RQG
sql/mysqld.cc:
  If we have already sent ok to client when we get an error, log this to stderr
  Don't disable option --log-output if CSV engine is not supported.
storage/maria/ha_maria.cc:
  Log queries to recovery log also in LOCK TABLES
storage/maria/ma_check.c:
  If param->max_trid is set, use this value instead of max_trid_in_system().
  This is used by recovery to set max_trid to max seen trid so far.
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE -> max_index_block_size (Style optimization)
storage/maria/ma_delete.c:
  Mark tables crashed early
  Write page number instead of page position to debug log.
  Added parameter to ma_log_delete() and ma_log_prefix() that is logged so that we can find where wrong log entries where generated.
  Fixed bug where a page was not proplerly written when same key tree had both an overflow and underflow when deleting a key.
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => max_index_block_size (Style optimization)
  ma_log_delete() now has extra parameter of how many bytes from end of page should be appended to log for page (for page overflows)
storage/maria/ma_key_recover.c:
  Added extra parameter to ma_log_prefix() to indicate what caused log entry.
  Update MARIA_PAGE->org_size when logging info about page.
  Much more DBUG_ASSERT()'s.
  Fix some bugs in maria_log_add() to handle page overflows.
  Added _ma_log_key_changes() to log crc of key page changes.
  If EXTRA_STORE_FULL_PAGE_IN_KEY_CHANGES is defines, log the resulting pages to log so one can trivally
  see how the resulting page should have looked like (for errors in CRC values)
storage/maria/ma_key_recover.h:
  Added _ma_log_key_changes() which is only called if EXTRA_DEBUG_KEY_CHANGES is defined.
  Updated function prototypes.
storage/maria/ma_loghandler.h:
  Added more values to en_key_debug, to get more exact location where things went wrong when logging to recovery log.
storage/maria/ma_open.c:
  Initialize share->max_index_block_size
storage/maria/ma_page.c:
  Added updating and testing of MARIA_PAGE->org_size
  Write page number instead of page postition to DBUG log
  Generate error if we read page with wrong data.
  Removed wrong assert: key_del_current != share->state.key_del.
  Simplify _ma_log_compact_keypage()
storage/maria/ma_recovery.c:
  Set param.max_trid to max seen trid before running repair table (used for alter table to create index)
storage/maria/ma_rt_key.c:
  Update call to _ma_log_delete()
storage/maria/ma_rt_split.c:
  Use _ma_log_key_changes()
  Update MARIA_PAGE->org_size
storage/maria/ma_unique.c:
  Remove casts
storage/maria/ma_write.c:
  keyinfo->block_length - KEYPAGE_CHECKSUM_SIZE => share->max_index_block_length.
  Updated calls to _ma_log_prefix()
  Changed code to use _ma_log_key_changes()
  Update ma_page->org_size
  Fixed bug in _ma_log_split() for pages that overflow
  Added KEY_OP_DEBUG logging to functions
  Log KEYPAGE_FLAG in all log entries
storage/maria/maria_def.h:
  Added SHARE->max_index_block_size
  Added MARIA_PAGE->org_size
storage/maria/trnman.c:
  Reset flags for new transaction.

64b639260c Bug#39932 "create table fails if column for FK is in different
case than in corr index".
      
Server was unable to find existing or explicitly created supporting
index for foreign key if corresponding statement clause used field
names in case different than one used in key specification and created
yet another supporting index.
In cases when name of constraint (and thus name of generated index)
was the same as name of existing/explicitly created index this led
to duplicate key name error.
      
The problem was that unlike all other code Key_part_spec::operator==()
compared field names in case sensitive fashion. As result routines
responsible for getting rid of redundant generated supporting indexes
for foreign key were not working properly for versions of field names
using different cases.

(backported from mysql-trunk)

  Make field name comparison case-insensitive like it is

d7d0f6390b Bug #54465: assert: field_types == 0 || field_types[field_pos]
== MYSQL_TYPE_LONGLONG

A MIN/MAX() function with a subquery as its argument could lead
to a debug assertion on debug builds or wrong data on release
ones.

The problem was a combination of the following factors:

- Item_sum_hybrid::fix_fields() might use the argument
(args[0]) to calculate 'hybrid_field_type' which was later used
to decide how the data should be sent to the client.

- Item_sum::make_field() might use the argument again to
calculate the field's type when sending result set metadata to
the client.

- The argument could be changed in between these two calls via
  Item::set_arg() leading to inconsistent metadata being
  reported.

Here is what was happening for the bug's test case:

1. Item_sum_hybrid::fix_fields() calculates hybrid_field_type
as MYSQL_TYPE_LONGLONG based on args[0] which is an
Item::SUBSELECT_ITEM at that time.

2. A temporary table is created to execute the
query. create_tmp_field_from_item() creates a Field_long object
according to the subselect's max_length.

3. The subselect item in Item_sum_hybrid is replaced by the
Item_field object referencing the newly created Field_long.

4. Item_sum::make_field() rightfully returns the
MYSQL_TYPE_LONG type when calculating the result set metadata.

5. When sending the actual data, Item::send() relies on the
virtual field_type() function which in our case returns
previously calculated hybrid_field_type == MYSQL_TYPE_LONGLONG.

It looks like the only solution is to never refer to the
argument's metadata after the result metadata has been
calculated in fix_fields(), since the argument itself may be
different by then. In this sense, Item_sum::make_field() should
never be used, because it may rely on the argument's metadata
and is only called after fix_fields(). The "default"
implementation in Item::make_field() should be used instead as
it relies only on field_type(), but not on the argument's type.

Fixed by removing Item_sum::make_field() so that the superclass
implementation Item::make_field() is always used.

e5bab33a2a Bug#53806: Wrong estimates for range query in partitioned MyISAM table
Bug#46754: 'rows' field doesn't reflect partition pruning

The EXPLAIN's result in 'rows' field
was evaluated to number of rows when the table was opened
(not from the table cache) and only the partitions left
after pruning was updated with its correct number
of rows.

The evaluation of the 'rows' field was using handler::records()
which is a potentially expensive call, and ignores the partitioning
pruning.

The fix was to use the handlers stats.records after updating it
with ::info(HA_STATUS_VARIABLE) instead.

mysql-test/r/partition_pruning.result:
  updated result
mysql-test/t/partition_pruning.test:
  Added test.
sql/sql_select.cc:
  Use ::info + stats.records instead of ::records().

6cf49743e8 Bug #53544: Server hangs during JOIN query in stored procedure
called twice in a row

Queries with nested joins could cause an infinite loop in the
server when used from SP/PS.

When flattening nested joins, simplify_joins() tracks if the
name resolution list needs to be updated by setting
fix_name_res to TRUE if the current loop iteration has done any
transformations to the join table list. The problem was that
the flag was not reset before the next loop iteration leading
to unnecessary "fixing" of the name resolution list which in
turn could lead to a loop (i.e. circularly-linked part) in that
list. This was causing problems on subsequent execution when
used together with stored procedures or prepared statements.

Fixed by making sure fix_name_res is reset on every loop
iteration.

  Added a test case for bug #53544.
mysql-test/t/join.test:
  Added a test case for bug #53544.
