correctly - crashes server !
Creating federated table with connect string containing empty
(zero-length) host name and port is evaluated as 0 (port is
incorrect, omitted or 0) crashes server.
This happens because federated calls strcmp() with NULL pointer.
Fixed by avoiding strcmp() call if hostname is set to NULL.

Federated may crash a server, return wrong result set, return
"ERROR 1030 (HY000): Got error 1430 from storage engine" message
when local (engine=federated) table has a key against nullable
column.
The problem was wrong implementation of function that creates
WHERE clause for remote query from key.

mysql-test/t/federated.test:
A test case for BUG#33946.
sql/ha_federated.cc:
Fixed that federated adds " IS NULL " condition to a remote query,
whereas "IS NOT NULL" requested by original query.
Fixed that federated didn't check for end of key buffer, didn't
setup key buffer pointer and remaining lenght of key buffer,
didn't add " AND " between conditions in case original query
has IS [NOT] NULL condition against nullable column.
Fixed that federated wrongly shifts key buffer pointer by extra
one byte when key part may be null (was: store_length + 1,
now: store_length).

filesort() uses file->estimate_rows_upper_bound() call to allocate
internal buffers. If this function returns a value smaller than
a number of row that will be returned later in find_all_keys(),
that can cause server crash.
Fixed by implementing ha_federated::estimate_rows_upper_bound() to
return maximum possible number of rows.
Present estimation for FEDERATED always returns 0 if the linked to the VIEW.

"Federated Denial of Service"
Federated storage engine used to attempt to open connections within
the ::create() and ::open() methods which are invoked while LOCK_open
mutex is being held by mysqld. As a result, no other client sessions
can open tables while Federated is attempting to open a connection.
Long DNS lookup times would stall mysqld's operation and a rogue
connection string which connects to a remote server which simply
stalls during handshake can stall mysqld for a much longer period of
time.
This patch moves the opening of the connection much later, when the
federated actually issues queries, by which time the LOCK_open mutex is
no longer being held.

when creating table
Federated tables had an artificially low maximum of key length,
because the handler failed to implement a method to return it and
the default value is taked from the prototype handler.
Now, implement that method and return the maximum possible key
length, which is that of InnoDB.

"Federated INSERT failures"
Federated does not correctly handle "INSERT...ON DUPLICATE KEY UPDATE"
However, implementing such support is not reasonably possible without
increasing complexity of the storage engine: checking that constraints
on remote server match local server and parsing error messages.
This patch causes 'ON DUPLICATE KEY' to fail with ER_DUP_KEY message
if a conflict occurs and not to fail silently.

Removed logic in ha_federated::write_row, which checks field query ids in the
loop which builds the query to run on the remote server.
mysql-test/r/federated.result:
"BUG #18764: Delete conditions causing inconsistencies in Federated tables"
New test results for test that verifies that one can insert to rows using
"insert into... select * from..", delete
them by id, then immediately insert them in the same way they were originally
inserted.

sql/ha_federated.cc:
"BUG #18764: Delete conditions causing inconsistencies in Federated tables"
Removed the logic in ha_federated::write_row which checked the query id of
each field and compared it to the thread query id.
Each field has a query id, and the problem used to be that if I did an insert
no fields specified, the field value would contain the last inserted value
for that field. The way to work around this was to see if the query id for
that field was the same as the current query id or of the rest of the field
query ids. If it wasn't, that told me the query didn't have the field value
specified.
Somewhere from when I wrote that code to now the problem went away, and there
was no longer the need for this logic.
Also removed the bool "has_fields", which needs not exist and using
table->s->fields is sufficient.
The Federated storage engine used Field methods that had arbitrary limits on
the amount of data they could process, which caused problems with data
over that limit (4K). By removing those Field methods and just using
features of the String class, we can avoid this problem.

before update trigger on NDB table".
Two main changes:
- We use TABLE::read_set/write_set bitmaps for marking fields used by
statement instead of Field::query_id in 5.1.
- Now when we mark columns used by statement we take into account columns
used by table's triggers instead of marking all columns as used if table
has triggers.
mysql-test/r/federated.result:
Changed test in order to make it work with RBR.
RBR changes the way in which we execute "DELETE FROM t1" statement - we don't
use handler::delete_all_rows() method if RBR is enabled (see bug#19066).
As result federated engine produces different sequences of statements for
remote server in non-RBR and in RBR cases. And this changes order of the
rows inserted by following INSERT statements.

sql/ha_partition.cc:
Added handling of HA_EXTRA_WRITE_CAN_REPLACE/HA_EXTRA_WRITE_CANNOT_REPLACE
to ha_partition::extra().
sql/item.cc:
Adjusted comment after merge. In 5.1 we use TABLE::read_set/write_set
bitmaps instead of Field::query_id for marking columns used.
sql/log_event.cc:
Write_rows_log_event::do_before_row_operations():
Now we explicitly inform handler that we want to replace rows so it can
promote operation done by write_row() to replace.
sql/mysql_priv.h:
Removed declaration of mark_fields_used_by_triggers_for_insert_stmt() which
is no longer used (we have TABLE::mark_columns_needed_for_insert() instead).
sql/sql_insert.cc:
Adjusted code after merge. Get rid of mark_fields_used_by_triggers_for_insert_stmt()
as now we use TABLE::mark_columns_needed_for_insert() for the same purprose.
Aligned places where we call this method with places where we call
mark_fields_used_by_triggers_for_insert() in 5.0.
Finally we no longer need to call handler::extra(HA_EXTRA_WRITE_CAN_REPLACE)
in case of REPLACE statement since in 5.1 write_record() marks all columns
as used before doing actual row replacement.
sql/sql_load.cc:
Adjusted code after merge. In 5.1 we use TABLE::mark_columns_needed_for_insert() instead of
mark_fields_used_by_triggers_for_insert_stmt() routine. We also no longer
need to call handler::extra(HA_EXTRA_RETRIEVE_ALL_COLS) if we execute LOAD
DATA REPLACE since in 5.1 write_record() will mark all columns as used before
doing actual row replacement.
sql/sql_trigger.cc:
Table_triggers_list::mark_fields_used():
We use TABLE::read_set/write_set bitmaps for marking fields used instead
of Field::query_id in 5.1.
sql/sql_trigger.h:
TABLE::mark_columns_needed_for_* methods no longer need to be friends of
Table_triggers_list class as intead of dirrectly accessing its private
members they can use public Table_triggers_list::mark_fields_used() method.
Also Table_triggers)list::mark_fields_used() no longer needs THD argument.
sql/table.cc:
TABLE::mark_columns_needed_for_*():
Now we mark columns which are really used by table's triggers instead of
marking all columns as used if table has triggers.
NDB table".
SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.
Also this patch contains the following cleanup of ha_ndbcluster code:
We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.
include/my_base.h:
Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
parameters for ha_extra() method. We use them to inform handler that
write_row() which tries to insert new row into the table and encounters
some already existing row with same primary/unique key can replace old
row with new row instead of reporting error.
mysql-test/r/federated.result:
Additional test for bug#18437 "Wrong values inserted with a before update

Item_trigger_field::setup_field():
Added comment explaining why we don't set Field::query_id in this method.
sql/mysql_priv.h:
mysql_alter_table() function no longer takes handle_duplicates argument.
Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
sql/sql_delete.cc:
Mark fields which are used by ON DELETE triggers so handler will retrieve
values for these fields.
sql/sql_insert.cc:
Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
in cases when it can promote insert operation done by write_row() to replace.
Also when we do REPLACE we want to store values for all columns so we should
inform handler about it.
Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
so handler can properly retrieve/restore values in these fields during
execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
Explicitly inform handler that we are doing LOAD DATA REPLACE (using
ha_extra() method) in cases when it can promote insert operation done by
write_row() to replace.
Also when we do replace we want to save (replace) values for all columns
so we should inform handler about it.
Finally to properly execute LOAD DATA for table with triggers we should
mark fields used by ON INSERT triggers as such so handler can properly
store values for these fields.
sql/sql_parse.cc:
mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:
Got rid of handle_duplicates argument in mysql_alter_table() and
copy_data_between_tables() functions. These functions were always
called with handle_duplicates == DUP_ERROR and thus contained dead
(and probably incorrect) code.
sql/sql_trigger.cc:
Added Table_triggers_list::mark_fields_used() method which is used to mark
fields read/set by triggers as such so handlers will be able properly
retrieve/store values in these fields.
sql/sql_trigger.h:
Table_triggers_list:
Added mark_fields_used() method which is used to mark fields read/set by
triggers as such so handlers will be able properly retrieve/store values
in these fields. To implement this method added 'trigger_fields' member
which is array of lists linking items for all fields used in triggers
grouped by event and action time.
sql/sql_update.cc:
Mark fields which are used by ON UPDATE triggers so handler will retrieve
and save values for these fields.

BUG #19773
Post-review changes, per Monty. 3rd patch, OK'd for push.
- Added index_read_idx_with_result_set, which uses the result set passed to it
- Hash by entire connection scheme
- Protected store_result result set for table scan by adding a method result set
to index_read_idx and index_read which is passed to index_read_with_result, which
in turn iterates over the single record via read_next.
This is a change from having two result sets in the first two patches.
This keeps the code clean and avoids the need for yet another result set.
- Rewrote ::position and ::rnd_pos to store position - if primary key use
primary key, if not, use record buffer.
- Rewrote get_share to store hash with connect string vs. table name
- delete_row added subtration of "records" by affected->rows
- Added read_next to handle what rnd_next used to do (converting raw record
to query and vice versa)
- Removed many DBUG_PRINT lines
- Removed memset initialisation since subsequent loop accomplishes
- Removed un-necessary mysql_free_result lines
