e46c139dd8 Bug#43748: crash when non-super user tries to kill the replication threads
Fine-tuning. Broke out comparison into method by
suggestion of Davi. Clarified comments. Reverting
test-case which I find too brittle; proper test
case in 5.1+.

4fe3425009 Added "pool-of-threads" handling (with libevent)
This is a backport of code from MySQL 6.0 with cleanups and extensions

The following new options are supported
configure options:
  --with-libevent                  ; Enable use of libevent, which is needed for pool of threads

mysqld options:
--thread-handling=pool-of-threads  ; Use a pool of threads to handle queries
--thread-pool-size=#               ; Define how many threads should be created to handle all queries
--extra-port=#                     ; Extra tcp port that uses the old one-thread-per-connection method
--extra-max-connections=#          ; Number of connections to accept to 'extra-port'
--test-ignore-wrong-options        ; Ignore setting an enum value to a wrong option (for mysql-test-run)

704b4845aa merge of 5.1-main into 5.1-maria. Myisam->Maria change propagation will follow.
There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.

mysys/thr_mutex.c:
  adding DBUG_PRINT here, so that we can locate where the warning is issued.

da1bf24852 BUG#38826 Race in MYSQL_LOG::purge_logs is impossible to debug in production
BUG#39325 Server crash inside MYSQL_LOG::purge_first_log halts replicaiton

The patch reverses the order of the purging and updating events for log and relay-log.info/index files respectively.
This solves the problem of having holes caused by crashes happening between updating info/index files and purging logs.

NOTE: This is a combined patch for BUG#38826 and BUG#39325. This patch is based on bugteam tree and takes into account reviewers suggestions.

41dd7b6b92 Bug#28323: Server crashed in xid cache operations
The problem was that the server did not robustly handle a
unilateral roll back issued by the Resource Manager (RM)
due to a resource deadlock within the transaction branch.
By not acknowledging the roll back, the server (TM) would
eventually corrupt the XA transaction state and crash.

The solution is to mark the transaction as rollback-only
if the RM indicates that it rolled back its branch of the
transaction.

f985e78775 Bug#24289 Status Variable "Questions" gets wrong values with Stored Routines
When running Stored Routines the Status Variable "Questions" was wrongly
incremented. According to the manual it should contain the "number of
statements that clients have sent to the server"
              
Introduced a new status variable 'questions' to replace the query_id
variable which currently corresponds badly with the number of statements
sent by the client.
            
The new behavior is ment to be backward compatible with 4.0 and at the
same time work with new features in a similar way.
            
This is a backport from 6.0

dcd050c550 Bug #34707: Row based replication: slave creates table within wrong database
The failure was caused by executing a CREATE-SELECT statement that creates a
table in another database than the current one. In row-based logging, the
CREATE statement was written to the binary log without the database, hence
creating the table in the wrong database, causing the following inserts to
fail since the table didn't exist in the given database.

Fixed the bug by adding a parameter to store_create_info() that will make
the function print the database name before the table name and used that
in the calls that write the CREATE statement to the binary log. The database
name is only printed if it is different than the currently selected database.

The output of SHOW CREATE TABLE has not changed and is still printed without
the database name.

mysql-test/suite/rpl/t/rpl_row_create_table.test:
  Added test to check that CREATE-SELECT into another database than the
  current one replicates.

  Adding parameter to calls to store_create_info().

84c1fffabb Fix for BUG#31612
"Trigger fired multiple times leads to gaps in auto_increment sequence".
The bug was that if a trigger fired multiple times inside a top
statement (for example top-statement is a multi-row INSERT,
and trigger is ON INSERT), and that trigger inserted into an auto_increment
column, then gaps could be observed in the auto_increment sequence,
even if there were no other users of the database (no concurrency).
It was wrong usage of THD::auto_inc_intervals_in_cur_stmt_for_binlog.
Note that the fix changes "class handler", I'll tell the Storage Engine API team.

mysql-test/r/trigger-trans.result:
  result; before the bugfix, the sequence was 1,2,4,6,8,10,12...
mysql-test/t/trigger-trans.test:
  test for BUG#31612
sql/handler.cc:
  See revision comment of handler.h.
  As THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative
  over all trigger invokations by the top statement, the
  second invokation of the trigger arrived in handler::update_auto_increment()
  with already one interval in
  THD::auto_inc_intervals_in_cur_stmt_for_binlog. The method thus
  believed it had already reserved one interval for that invokation,
  thus reserved a twice larger interval (heuristic when we don't know
  how large the interval should be: we grow by powers of two). InnoDB
  thus increased its internal per-table auto_increment counter by 2
  while only one row was to be inserted. Hence a gap in the sequence.
  The fix is to use the new handler::auto_inc_intervals_count.
  Note that the trigger's statement knows how many rows it is going
  to insert, but provides estimation_rows_to_insert == 0 (see comments
  in sql_insert.cc why triggers don't call handler::ha_start_bulk_insert()).
  * removing white space at end of line
  * we don't need to maintain THD::auto_inc_intervals_in_cur_stmt_for_binlog
  if no binlogging or if row-based binlogging. Using auto_inc_intervals_count in
  the heuristic makes the heuristic independent of binary logging, which is good.
sql/handler.h:
  THD::auto_inc_intervals_in_cur_stmt_for_binlog served
   - for binlogging
   - as a heuristic when we have no estimation of how many records the
     statement will insert.
  But the first goal needs to be cumulative over all statements which
  form a binlog event, while the second one needs to be attached to each
  statement. THD::auto_inc_intervals_in_cur_stmt_for_binlog is cumulative,
  leading to BUG#31612. So we introduce handler::auto_inc_intervals_count
  for the second goal. See the revision comment of handler.cc.
  A smaller issue was that, even when the binlog event was only one
  statement (no triggers, no stored functions),
  THD::auto_inc_intervals_in_cur_stmt.nb_elements() could be lower than
  the number of reserved intervals (fooling the heuristic), because its
  append() method collapses two contiguous intervals in one.
  Note that as auto_inc_intervals_count is in class 'handler' and not
  in class 'THD', it does not need to be handled in
  THD::reset|restore_sub_statement_state().
sql/log.cc:
  Comment is wrong: if auto_increment is second, in handler::update_auto_increment()
  'append' is false and so auto_inc_intervals_in_cur_stmt_for_binlog
  is empty, we do not come here.

02a4354044 Bug #32709: Assertion failed: trx_data->empty(), file log.cc
The assertion indicates that some data was left in the transaction
cache when the server was shut down, which means that a previous
statement did not commit or rollback correctly.

What happened was that a bug in the rollback of a transactional
table caused the transaction cache to be emptied, but not reset.
The error can be triggered by having a failing UPDATE or INSERT,
on a transactional table, causing an implicit rollback.

Fixed by always flushing the pending event to reset the state
properly.


mysql-test/extra/rpl_tests/rpl_row_basic.test:
  Testing that a failed update (that writes some rows to the
  transaction cache) does not cause the transaction cache to
  hold on to the data or forget to reset the transaction cache.
sql/log.cc:
  Added call to remove pending event when the transaction cache
  is emptied instead of written to binary log. The call will also
  clear the outstanding table map count so that the cache is not
  left it in a state of "empty but not reset".
  
  Added function MYSQL_BIN_LOG::remove_pending_rows_event().

5cd9d96a68 Bug #34707: Row based replication: slave creates table within wrong database
The failure was caused by executing a CREATE-SELECT statement that creates a
table in another database than the current one. In row-based logging, the
CREATE statement was written to the binary log without the database, hence
creating the table in the wrong database, causing the following inserts to
fail since the table didn't exist in the given database.

Fixed the bug by adding a parameter to store_create_info() that will make
the function print the database name before the table name and used that
in the calls that write the CREATE statement to the binary log. The database
name is only printed if it is different than the currently selected database.

The output of SHOW CREATE TABLE has not changed and is still printed without
the database name.

a018e98cba BUG#37051 Replication rules not evaluated correctly
The problem of this bug is that we need to get the list of tables
to be updated for a multi-table update statement, which requires to
open all the tables referenced by the statement and resolve all
the fields involved in update in order to figure out the list of
tables for update. However if there are replicate filter rules,
some tables might not exist on slave and result in a failure
before we could examine the filter rules.

I think the whole problem can not be solved on slave alone,
the master must record and send the information of tables
involved for update to slave, so that the slave do not need to
open all the tables referenced by the multi-table update statement to
figure out which tables are involved for update.

So a status variable is added to Query_log event to store the
value of table map for update on master. And on slave, it will
try to get the value of this variable and use it to examine
filter rules without opening any tables on slave, if this values
is not available, the old approach is used and thus the bug will
still occur for when replicating from old masters.


sql/sql_class.h:
  add member table_map_for_update to THD
sql/sql_parse.cc:
  check filter rules by using table_map_for_update value

  save the value of table_map_for_update

e73e7bb9ae Bug#35577 (CREATE PROCEDURE causes either crash or syntax error depending on
build)

The crash was caused by freeing the internal parser stack during the parser
execution.
This occured only for complex stored procedures, after reallocating the parser
stack using my_yyoverflow(), with the following C call stack:
- MYSQLparse()
- any rule calling sp_head::restore_lex()
- lex_end()
- x_free(lex->yacc_yyss), xfree(lex->yacc_yyvs)

The root cause is the implementation of stored procedures, which breaks the
assumption from 4.1 that there is only one LEX structure per parser call.

The solution is to separate the LEX structure into:
- attributes that represent a statement (the current LEX structure),
- attributes that relate to the syntax parser itself (Yacc_state),
so that parsing multiple statements in stored programs can create multiple
LEX structures while not changing the unique Yacc_state.

Now, Yacc_state and the existing Lex_input_stream are aggregated into
Parser_state, a structure that represent the complete state of the (Lexical +
Syntax) parser.
