969b71653d BUG#26881 - Large MERGE tables report incorrect specification when no
differences in tables
Certain merge tables were wrongly reported as having incorrect definition:
- Some fields that are 1 byte long (e.g. TINYINT, CHAR(1)), might
  be internally casted (in certain cases) to a different type on a
  storage engine layer. (affects 4.1 and up)
- If tables in a merge (and a MERGE table itself) had short VARCHAR column (less
  than 4 bytes) and at least one (but not all) tables were ALTER'ed (even to an
  identical table: ALTER TABLE xxx ENGINE=yyy), table definitions went ouf of
  sync. (affects 4.1 only)

This is fixed by relaxing a check for underlying conformance and setting
field type to FIELD_TYPE_STRING in case varchar is shorter than 4
when a table is created.


myisam/mi_create.c:
  Added a comment.
mysql-test/r/merge.result:
  A test case for bug#26881.
mysql-test/t/merge.test:
  A test case for bug#26881.
sql/ha_myisam.cc:
  Relaxed some checks performed by check_definition():
  As comparing of fulltext keys (and key segments) is not yet implemented,
  only return an error in case one of keys is fulltext and other is not.
  Otherwise, if both keys are fulltext, accept them as is.
  
  As comparing of spatial keys (and key segments) is not yet implemented,
  only return an error in case one of keys is spatial and other is not.
  Otherwise, if both keys are spatial, accept them as is.
  
  A workaround to handle situation when field is casted from FIELD_SKIP_ZERO
  to FIELD_NORMAL. This could happen only in case field length is 1 and row
  format is fixed.
sql/sql_parse.cc:
  When a table that has varchar field shorter than 4 is created, field type is
  set to FIELD_TYPE_VAR_STRING. Later, when a table is modified using alter
  table, field type is changed to FIELD_TYPE_STRING (see Field_string::type).
  That means HA_OPTION_PACK_RECORD flag might be lost and thus null_bit might
  be shifted by alter table, in other words alter table doesn't create 100%
  equal table definition.
  
  This is usually not a problem, since when a table is created/altered,
  definition on a storage engine layer is based on one that is passed from
  sql layer. But it is a problem for merge engine - null_bit is shifted when
  a table (merge or underlying) is altered.
  
  Set field type to FIELD_TYPE_STRING in case FIELD_TYPE_VAR_STRING is shorter
  than 4 when a table is created as it is done in Field::type.

114e5b8ddb Bug#23240 --init-file statements with NOW() reports '1970-01-01 11:00:00'as the date time
- Starting time of a query sent by file bootstrapping wasn't initialized
  and starting time defaulted to 0. This later used value by the Now-
  item and is translated to 1970-01-01 11:00:00.
- marking the time with thd->set_time() before the call to 
  mysql_parse resolves this issue.

a195ad5ea2 Bug#22943 syscall pruning in libmysql
- Set the timeout values only where needed


sql/mysql_priv.h:
  Add new functions for setting read and write timeout on "net"
sql/mysqld.cc:
  - Move the setting of "read_timeout" to the value of "connect_timeout" to
    just before 'check_connection' which is the function where we want
    to use the different timeout
  - With the new functions to set timeout on "net", there is no need to
    specifically set the default wait_timeout on windows.
sql/net_serv.cc:
  Add new functions for setting read and write timeout of "net, when
  server is compiled not to use alarms it will set the write/read timeout
  directly on connection using 'vio_timeout'(using setsockopt if socket)
sql/repl_failsafe.cc:
  Put unused code within "#if NOT_USED"
sql/set_var.cc:
  Use 'net_set_*_timeout' when adjusting timeout value
  on the current connection
sql/slave.cc:
  The read timeout used when connecting to master server is set
  using 'mysql_options' in 'connect_to_master' function
sql/sql_parse.cc:
  - Set read and write timeout values to "connect_timeout" during
  connect phase
  - Use "read_timeout" value during sslaccept phase, since this is during
  connect phase it implies "connect-timeout"
  - Set read and write timeout value back to default after connect phase
  - Set "read_timeout" to "wait_timeout" while waiting for client.
sql/sql_repl.cc:
  Set "read_timeout" to "wait_timeout" while ask other mysqld to send file
sql-common/client.c:
  Call 'vio_timeout' to set up the read and write timeout's for the
  newly created connection. It only need to be done once at connect time.
vio/vio.c:
  Use 'vio_timeout' for setting timeout also on an SSL connection
  since they both use sockets
vio/viossl.c:
  Remove 'vio_ssl_timeout' function

e47ded8114 A fix and test cases for
Bug#4968 "Stored procedure crash if cursor opened on altered table"
Bug#19733 "Repeated alter, or repeated create/drop, fails"
Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from 
stored procedure."
Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing"
Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server"

Test cases for bugs 4968, 19733, 6895 will be added in 5.0.

Re-execution of CREATE DATABASE, CREATE TABLE and ALTER TABLE 
statements in stored routines or as prepared statements caused
incorrect results (and crashes in versions prior to 5.0.25).
In 5.1 the problem occured only for CREATE DATABASE, CREATE TABLE
SELECT and CREATE TABLE with INDEX/DATA DIRECTOY options).

The problem of bugs 4968, 19733, 19282 and 6895 was that functions
mysql_prepare_table, mysql_create_table and mysql_alter_table were not
re-execution friendly: during their operation they used to modify contents
of LEX (members create_info, alter_info, key_list, create_list),
thus making the LEX unusable for the next execution.
In particular, these functions removed processed columns and keys from
create_list, key_list and drop_list. Search the code in sql_table.cc 
for drop_it.remove() and similar patterns to find evidence.

The fix is to supply to these functions a usable copy of each of the
above structures at every re-execution of an SQL statement. 

To simplify memory management, LEX::key_list and LEX::create_list
were added to LEX::alter_info, a fresh copy of which is created for
every execution.

The problem of crashing bug 22060 stemmed from the fact that the above 
metnioned functions were not only modifying HA_CREATE_INFO structure in 
LEX, but also were changing it to point to areas in volatile memory of 
the execution memory root.
 
The patch solves this problem by creating and using an on-stack
copy of HA_CREATE_INFO (note that code in 5.1 already creates and
uses a copy of this structure in mysql_create_table()/alter_table(),
but this approach didn't work well for CREATE TABLE SELECT statement).


mysql-test/r/ps.result:
  Update test results (Bug#19182, Bug#22060)
mysql-test/t/ps.test:
  Add a test case for Bug#19182, Bug#22060 (4.1-only parts)
sql/mysql_priv.h:
  LEX::key_list and LEX::create_list were moved to LEX::alter_info.
  Update declarations to use LEX::alter_info instead of these two
  members.
sql/sql_class.h:
  Replace pair<columns, keys> with an instance of Alter_info in
  select_create constructor. We create a new copy of Alter_info
  each time we re-execute SELECT .. CREATE prepared statement.
sql/sql_insert.cc:
  Adjust to a new signature of create_table_from_items.
sql/sql_lex.cc:
  Implement Alter_info::Alter_info that would make a "deep" copy
  of all definition lists (keys, columns).
sql/sql_lex.h:
  Move key_list and create_list to class Alter_info. Implement
  Alter_info::Alter_info that can be used with PS and SP.
sql/sql_list.h:

  of all list nodes.
sql/sql_parse.cc:
  Adjust to new signatures of mysql_create_table, mysql_alter_table,
  select_create. Functions mysql_create_index and mysql_drop_index has
  become identical after initialization of alter_info was moved to the 
  parser, and were merged. Flag enable_slow_log was not updated for 
  SQLCOM_DROP_INDEX, which is a bug. Just like CREATE INDEX, DROP INDEX
  is currently done via complete table rebuild and is rightfully a slow
  administrative statement.
sql/sql_show.cc:
  Adjust mysqld_show_create_db to a new signature.
sql/sql_table.cc:

f603c1cce8 BUG#21726: Incorrect result with multiple invocations of LAST_INSERT_ID.
Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures.  However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:

  - LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).

  - LAST_INSERT_ID() could return the value generated by current
    statement if the call happens after the generation, like in

      CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
      INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());

  - Redundant binary log LAST_INSERT_ID_EVENTs could be generated.

in multi-table DELETE the set of tables to delete from actually 
references then tables in the other list, e.g:

So we must turn off table name syntactical validity check for alias_of_t1

eadcf20081 bug #16017 (memory leaks in embedded server)
There actually was 3 different problems -
hash_user_connections wasn't cleaned
one strdupped database name wasn't freed
and stmt->mem_root wasn't cleaned as it was
replased with mysql->field_alloc for result
For the last one - i made the library using stmt's
fields to store result if it's the case.


include/mysql.h:
  statement pointer added to the advanced_command to be checked in
  embedded server
include/sql_common.h:
  stmt added to the cli_advanced_command interface
libmysql/libmysql.c:
  stmt pointer now sent to advanced_command
libmysqld/embedded_priv.h:
  it's enough to send database name to check_embedded_connection
libmysqld/lib_sql.cc:
  Now we store result directly in the MYSQL_STMT structure to
  avoid extra copying
libmysqld/libmysqld.c:
  it's enough to only send database pointer to check_embedded_connection
sql-common/client.c:
  stmt fake attribute added to cli_advanced_command
sql/sql_parse.cc:
  hash_user_connections isn't used if no access checks compiled

2264b64473 Fixed bug#19225: unchecked error results in server crash
In multi-table delete a table for delete can't be used for selecting in
subselects. Appropriate error was raised but wasn't checked which leads to a
crash at the execution phase.

The mysql_execute_command() now checks for errors before executing select
for multi-delete.

9225a51c58 Fixed bug #18767.
The bug caused wrong result sets for union constructs of the form
(SELECT ... ORDER BY order_list1 [LIMIT n]) ORDER BY order_list2.
For such queries order lists were concatenated and limit clause was
completely neglected.

  sequence.

  Yet if there is neither ORDER BY nor LIMIT in the single-select
  union construct
  (SELECT ...) ORDER BY order_list
  then it is still handled as simple select with an order clause.

9cf3f255bd A fix and a test case for Bug#13134 "Length of VARCHAR() utf8
column is increasing when table is recreated with PS/SP":
make use of create_field::char_length more consistent in the code.
Reinit create_field::length from create_field::char_length
for every execution of a prepared statement (actually fixes the 
bug).


mysql-test/r/ps.result:
  Test results fixed (Bug#13134)
mysql-test/t/ps.test:
  A test case for Bug#13134 "Length of VARCHAR() utf8 column is 
  increasing when table is recreated with PS/SP"
sql/field.cc:
  Move initialization of create_field::char_length to the constructor
  of create_field.
sql/field.h:
  Rename chars_length to char_length (to be consistent with
  how this term is used throughout the rest of the code).
sql/sql_parse.cc:
  Initialize char_length in add_field_to_list. This function
  effectively works as another create_field constructor.
sql/sql_table.cc:
  Reinit length from char_length for every field in 
  mysql_prepare_table. This is not needed if we're executing
  a statement for the first time, however, at subsequent executions
  length contains the number of bytes, not characters (as it's expected 
  to).

f6cac54bf6 BUG#5390 - problems with merge tables
Problem #1: INSERT...SELECT, Version for 4.1.
INSERT ... SELECT with the same table on both sides (hidden
below a MERGE table) does now work by buffering the select result.
The duplicate detection works now after open_and_lock_tables() 
on the locks.
I did not find a test case that failed without the change in
sql_update.cc. I made the change anyway as it should in theory
fix a possible MERGE table problem with multi-table update.

f89424f8b6 fix for BUG#11139 (multi-delete with alias breaking replication if table rules are
present): the problem originally was that the tables in auxilliary_tables did not have 
the correct real_name, which caused problems in the second call to tables_ok(). 
The fix corrects the real_name problem, and also sets the updating flag properly, 
which makes the second call to tables_ok() unnecessary.
