b7527f6b72 Bug #29579 Clients using SSL can hang the server
Added an option to yassl to allow "quiet shutdown" like openssl does. This option causes the SSL libs to NOT perform the close_notify handshake during shutdown. This fixes a hang we experience because we hold a lock during socket shutdown.

9dc3088f9e A fix and a test case for Bug#26141 mixing table types in trigger
causes full table lock on innodb table.
Also fixes Bug#28502 Triggers that update another innodb table 
will block on X lock unnecessarily (duplciate).
Code review fixes.

Both bugs' synopses are misleading: InnoDB table is
not X locked. The statements, however, cannot proceed concurrently, 
but this happens due to lock conflicts for tables used in triggers,
not for the InnoDB table. 

If a user had an InnoDB table, and two triggers, AFTER UPDATE and 
AFTER INSERT, competing for different resources (e.g. two distinct
MyISAM tables), then these two triggers would not be able to execute
concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would
not be able to run concurrently. 
The problem had other side-effects (see respective bug reports).

This behavior was a consequence of a shortcoming of the pre-locking
algorithm, which would not distinguish between different DML operations
(e.g. INSERT and DELETE) and pre-lock all the tables
that are used by any trigger defined on the subject table.

The idea of the fix is to extend the pre-locking algorithm to keep track,
for each table, what DML operation it is used for and not
load triggers that are known to never be fired.

mysql-test/t/trigger.test:
  Add a test case for Bug#28502 Triggers that update another innodb 
  table will block echo on X lock unnecessarily. Add more test 
  coverage for triggers.
sql/item.h:
  enum trg_event_type is needed in table.h
sql/sp.cc:
  Take into account table_list->trg_event_map when determining
  what tables to pre-lock. 
  
  After this change, if we attempt to fire a 
  trigger for which we had not pre-locked any tables, error
  'Table was not locked with LOCK TABLES' will be printed.
  This, however, should never happen, provided the pre-locking
  algorithm has no programming bugs.
  
  Previously a trigger key in the sroutines hash was based on the name 
  of the table the trigger belongs to. This was possible because we would
  always add to the pre-locking list all the triggers defined for a table when
  handling this table.
  Now the key is based on the name of the trigger, owing
  to the fact that a trigger name must be unique in the database it
  belongs to.
sql/sp_head.cc:
  Generate sroutines hash key in init_spname(). This is a convenient
  place since there we have all the necessary information and can
  avoid an extra alloc.
  
  Maintain and merge trg_event_map when adding and merging elements
  of the pre-locking list.
sql/sp_head.h:
  Add ,m_sroutines_key member, used when inserting the sphead for a
  trigger into the cache of routines used by a statement.
  Previously the key was based on the table name the trigger belonged
  to, since for a given table we would add to the sroutines list
  all the triggers defined on it.
sql/sql_lex.cc:
  Introduce a new lex step: set_trg_event_type_for_tables().
  It is called when we have finished parsing but before opening
  and locking tables. Now this step is used to evaluate for each
  TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any,
  it is used in.
  In future this method could be extended to aggregate other information
  that is hard to aggregate during parsing.
sql/sql_lex.h:
  Add declaration for set_trg_event_type_for_tables().
sql/sql_parse.cc:
  Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs.
sql/sql_prepare.cc:

sql/sql_view.cc:
  Call set_trg_event_type_for_tables() after MYSQLparse().
sql/sql_yacc.yy:
  Move assignment of sp_head::m_type before calling sp_head::init_spname(), 
  one is now used inside another.
sql/table.cc:
  Implement TABLE_LIST::set_trg_event_map() - a method that calculates
  wh triggers may be fired on this table when executing a statement.
sql/table.h:
  Add missing declarations.
  Move declaration of trg_event_type from item.h (it will be needed for 
  trg_event_map bitmap when we start using Bitmap template instead
  of uint8).

30810f80b1 Bug#28249 Query Cache returns wrong result with concurrent insert / certain lock
A race condition in the integration between MyISAM and the query cache code 
caused the query cache to fail to invalidate itself on concurrently inserted
data.

This patch fix this problem by using the existing handler interface which, upon
each statement cache attempt, compare the size of the table as viewed from the 
cache writing thread and with any snap shot of the global table state. If the
two sizes are different the global table size is unknown and the current
statement can't be cached.

The SELECT INTO OUTFILE FIELDS ENCLOSED BY digit or minus sign,
followed by the same LOAD DATA INFILE statement, used wrond encoding
of non-string fields contained the enclosed character in their text
representation.

Example:
  SELECT 15, 9 INTO OUTFILE 'text' FIELDS ENCLOSED BY '5';

Old encoded result in the text file:
  5155 595
         ^ was decoded as the 1st enclosing character of the 2nd field;
        ^ was skipped as garbage;
  ^    ^ was decoded as a pair of englosing characters of the 1st field;
      ^   was decoded as traling space of the first field;
    ^^ was decoded as a doubled enclosed character.

New encoded result in the text file:
  51\55 595
  ^   ^ pair of enclosing characters of the 1st field;
    ^^ escaped enclosed character.

e8966deecc A fix and a test case for Bug#29050 Creation of a legal stored procedure
fails if a database is not selected prior.

The problem manifested itself when a user tried to
create a routine that had non-fully-qualified identifiers in its bodies
and there was no current database selected.

This is a regression introduced by the fix for Bug 19022:

The patch for Bug 19022 changes the code to always produce a warning
if we can't resolve the current database in the parser. 
In this case this was not necessary, since even though the produced
parsed tree was incorrect, we never re-use sphead
that was obtained at first parsing of CREATE PROCEDURE.
The sphead that is anyhow used is always obtained through db_load_routine,
and there we change the current database to sphead->m_db before
calling yyparse.

The idea of the fix is to resolve the current database directly using 
lex->sphead->m_db member when parsing a stored routine body, when
such is present.

This patch removes the need to reset the current database
when loading a trigger or routine definition into SP cache.
The redundant code will be removed in 5.1.

  if we're parsing a stored routine, not the default database in
  THD. The default database is needed to initialize tables->db
  when the database part was not explicitly specified in the identifier.
sql/sql_yacc.yy:
  Use st_lex::copy_db_to() in the parser, rather than

5d88b654ed Fixed bug #29392.
This bug may manifest itself for select queries over a multi-table view
that includes an ORDER BY clause in its definition. If the select list of 
the query contains references to the same view column with different
aliases the names of the columns in the result output will be nevertheless
the same, coinciding with one of the alias.

The bug happened because the method Item_ref::get_tmp_table_item that
was inherited by the class Item_direct_view_ref ignored the fact that
the name of the view column reference must be inherited by the fields
of the temporary table that was created in order to get the result rows
sorted.

b1ec3b534d A fix and a teset case for Bug#28551 The warning
'No database selected' is reported when calling stored procedures

Remove the offending warning introduced by the fix for Bug
25082
This minimal patch relies on the intrinsic knowledge of the fact that
mysql_change_db is never called with 'force_switch' set to TRUE
when such a warning may be needed:
 * every stored routine belongs to a database (unlike, e.g., a 
user defined function, which does not), so if we're activating the
database of a stored routine, it can never be NULL.
Therefore, this branch is never called for activation.
 * if we're restoring the 'old' current database after routine
execution is complete, we should not issue a warning, since it's OK to 
call a routine without having previously selected the current database.

TODO: 'force_switch' is an ambiguous flag, since we do not actually
have to 'force' the switch in case of stored routines at all.
When we activate the routine's database, we should perform
all the checks as in case of 'use db', and so we already do (in this
case 'force_switch' is unused).
When we load a routine into cache, we should not use mysql_change_db
at all, since there it's enough to call thd->reset_db(). We
do it this way for triggers, but code for routines is different (wrongly). 

TODO: bugs are lurking in replication, since it bypasses mysql_change_db
and calls thd->[re_]set_db to set the current database.
The latter does not change thd->db_charset, thd->sctx->db_access
and thd->variables.collation_database (and this may have nasty side
effects).

These todo items are to be addressed in a separate patch, if at all.

166d3c9186 Fixed bug #29294.
The `SELECT 'r' INTO OUTFILE ... FIELDS ENCLOSED BY 'r' ' statement
encoded the 'r' string to a 4 byte string of value x'725c7272'
(sequence of 4 characters: r\rr).
The LOAD DATA statement decoded this string to a 1 byte string of
value x'0d' (ASCII Carriage Return character) instead of the original
'r' character.
The same error also happened with the FIELDS ENCLOSED BY clause
followed by special characters: 'n', 't', 'r', 'b', '0', 'Z' and 'N'.

NOTE 1: This is a result of the undocumented feature: the LOAD DATA INFILE
recognises 2-byte input sequences like \n, \t, \r and \Z in addition
to documented 2-byte sequences: \0 and \N. This feature should be
documented (here backspace character is a default ESCAPED BY character,
in the real-life example it may be any ESCAPED BY character).

NOTE 2, changed behaviour:
Now the `SELECT INTO OUTFILE' statement with the `FIELDS ENCLOSED BY'
clause followed by one of: 'n', 't', 'r', 'b', '0', 'Z' or 'N' characters
encodes this special character itself by doubling it ('r' --> 'rr'),
not by prepending it with an escape character.


sql/sql_class.h:
  Fixed bug #29294.
  The ESCAPE_CHARS macro constant is defined to enumerate
  symbolic names of espace-sequences like  '\n', '\t' etc.
  The select_export::is_ambiguous_field_sep field has been added
  to distinguish special values of the field_sep field from
  another values (see ESCAPE_CHARS).
sql/sql_class.cc:
  Fixed bug #29294.
  The select_export::send_data method has been modified to
  encode special values of the field_sep field by
  doubling of those values instead of prepending them with a
  value of the escape_char field.
  Example: The SELECT 'r' INTO OUTFILE FIELDS ENCLOSED BY 'r'
  now produces the 'rr' output string instead of x'5c72'
  (i.e. instead of sequence of 2 bytes: \ and r).
sql/sql_load.cc:
  Fixed bug #29294.
  Added commentary for the READ_INFO::unescape method.
