table
Performance schema discovery fails if connection has no active database set.
This happened due to restriction in SQL parser: table name with no database name
is ambiguous in such case.
Fixed by temporary substitution of default database with being discovered table
database.
Taking into account implicit dependence of constant view field from nullable table of left join added.
Fixed finding real table to check if it turned to NULL (materialized view & derived taken into account)
Removed incorrect uninitialization.
This bug manifests due to wrong computation and evaluation of
keyinfo->key_length. The issues were:
* Using table->file->max_key_length() as an absolute value that must not be
reached for a key, while it represents the maximum number of bytes
possible for a table key.
* Incorrectly computing the keyinfo->key_length size during
KEY_PART_INFO creation. The metadata information regarding the key
such the field length (for strings) was added twice.
* error reporting was never needed
* avoid useless transformaton hton to db_type to hton
* in many cases the engine was guaranteed to exist, add asserts
* use ha_default_handlerton() instead of ha_checktype(DB_TYPE_DEFAULT)
Call mysql_derived_reinit() if we are reusing view.
This is needed as during a previous error condition the view may not have been reset

Always reset merged_for_insert (no reason to not do that)

The srid variable was used uninitialised when the field wasn't GIS.
Only problem is that it makes the debugger unhappy. Still added
the initialization.
The GEOMETRY field metadata is stored in the FRM file.
SRID for a spatial column now can be stored, it was added to the CREATE TABLE syntax,
so the AddGeometryData() stored procedure is now possible. Script adding the required Add/DropGeometryColumn sp-s added.
length/dec/charset are still in LEX, because they're also used
for CAST and dynamic columns.
also
1. fix "MDEV-7041 COLLATION(CAST('a' AS CHAR BINARY)) returns a wrong result"
2. allow BINARY modifier in stored function RETURN clause
3. allow "COLLATION without CHARSET" in SP/SF (parameters, RETURN, DECLARE)
4. print correct variable name in error messages for stored routine parameters
Description: When querying a subset of columns from the information_schema.TABLES
Analysis: When information about tables is collected for statements like
"SELECT ENGINE FROM I_S.TABLES" we do not perform full-blown table opens
in SE, instead we only use information from table shares from the Table
Definition Cache or .FRMs. Still in order to simplify I_S implementation
mock TABLE objects are created from TABLE_SHARE during this process.
This is done by calling open_table_from_share() function with special
arguments. Since this function always increments "Opened_tables" counter,
calls to it can be mistakingly interpreted as full-blown table opens in SE.
Note that claim that "'SELECT ENGINE FROM I_S.TABLES' statement doesn't
use Table Cache" is nevertheless factually correct. But it misses the
point, since such statements a) don't use full-blown TABLE objects and
therefore don't do table opens b) still use Table Definition Cache.
Fix: We are now incrementing the counter when db_stat(i.e open flags for ha_open(
we have considered an optimization which would use TABLE objects from
Table Cache when available instead of constructing mock TABLE objects,
but found it too intrusive for stable releases.
reset default fields not for every modified row, but only once,
at the beginning, as the set of modified fields doesn't change.
exception: INSERT ... ON DUPLICATE KEY UPDATE - the set of fields
does change per row and in that case we reset default fields per row.
- TABLE::create_key_part_by_field() should not set PART_KEY_FLAG in field->flags
= The reason is that it is used by hash join code which calls it to create a hash
table lookup structure. It doesn't create a real index.
= Another caller of the function is TABLE::add_tmp_key(). Made it to set the flag itself.
- The differences in join_cache.result could also be observed before this patch: one
could put "FLUSH TABLES" before the queries and get exactly the same difference.
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.
This patch fixes so that we always include my_global.h or my_config.h before we include any other files.
Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
"always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

Merged lp:maria/maria-10.0-galera up to revision 3879.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.

BACKGROUND:
This bug is a followup on Bug#16368875.
The assertion failure happens because in SQL layer the key
does not get promoted to PRIMARY KEY but InnoDB takes it
as PRIMARY KEY.
ANALYSIS:
Here we are trying to create an index on POINT (GEOMETRY)
data type which is a type of BLOB (since GEOMETRY is a
subclass of BLOB).
In general, we can't create an index over GEOMETRY family
type field unless we specify the length of the
keypart (similar to BLOB fields).
Only exception is the POINT field type. The POINT column
max size is 25. The problem is that the field is not treated
as PRIMARY KEY when we create a index on POINT column using
its max column size as key part prefix. The fix would allow
index on POINT column to be treated as PRIMARY KEY.
FIX:
Patch for Bug#16368875 is extended to take into account
GEOMETRY datatype, POINT in particular to consider it
as PRIMARY KEY in SQL layer.

Adapt default_tmp_storage_engine implementation from mysql-5.6
New feature (as compared to 5.6), default_tmp_storage_engine=NULL
means that temporary tables will use default_storage_engine value.
This makes the behavior backward compatible.
