binlog coordinates corresponding to the dump".
The good news is that now mysqldump can be used to get an online backup of InnoDB *which works for
point-in-time recovery and replication slave creation*. Formerly, mysqldump --master-data --single-transaction
used to call in fact mysqldump --master-data, so the dump was not an online dump (took big lock all time of dump).
The only lock which is now taken in this patch is at the beginning of the dump: mysqldump does:
FLUSH TABLES WITH READ LOCK; START TRANSACTION WITH CONSISTENT SNAPSHOT; SHOW MASTER STATUS; UNLOCK TABLES;
so the lock time is in fact the time FLUSH TABLES WITH READ LOCK takes to return (can be 0 or very long, if
a table is undergoing a huge update).
I have done some more minor changes listed in the paragraph of mysqldump.c.
WL#2237 "WITH CONSISTENT SNAPSHOT clause for START TRANSACTION":
it's a START TRANSACTION which additionally starts a consistent read on all
capable storage engine (i.e. InnoDB). So, can serve as a replacement for
BEGIN; SELECT * FROM some_innodb_table LIMIT 1; which starts a consistent read too.
client/mysqldump.c:
Main change: mysqldump --single-transaction --master-data is now able to, at the same time,
take an online dump of InnoDB (using consistent read) AND get the binlog position corresponding to this dump
(before, using the two options used to silently cancel --single-transaction).
This uses the new START TRANSACTION WITH CONSISTENT SNAPSHOT syntax.
Additional changes:
a) cleanup:
- DBerror calls exit() so some code was unneeded
- no need to call COMMIT at end, leave disconnection do the job
- mysql_query_with_error_report()
b) requirements I had heard from colleagues:
- --master-data now requires an argument, to comment out ("--") the CHANGE MASTER or not
(commenting had been asked for point-in-time recovery when replication is not necessary).
- --first-slave is renamed to --lock-all-tables
c) more sensible behaviours (has been discussed internally):
- if used with --master-data, --flush-logs is probably intended to get a flush synchronous
with the dump, not one random flush per dumped db.
- disabled automatic reconnection as, at least, SQL_MODE would be lost (and also, depending
on options, LOCK TABLES, BEGIN, FLUSH TABLES WITH READ LOCK).
include/mysqld_error.h:
an error if START TRANSACTION WITH CONSISTENT SNAPSHOT is called and there is no consistent-read capable storage engine
(idea ((C) PeterG) is that it's a bit like CREATE TABLE ENGINE=InnoDB when there is no support for InnoDB).

aware plus it fixes the case when RAND is used in prepared
statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared
statement, so if some execution had set thd->time_zone_used
or thd->rand_used they would not be reset until next mysql_parse.
Some of post-review fixes done.

sql/sql_parse.cc:
Split mysql_init_query into two functions: mysql_reset_thd_for_next_query,
which is used in PS and conventional execution, and lex_start, used only
when we want to parse something.
Fix init_connect to use initialized THD.
sql/sql_prepare.cc:
Deploy mysql_reset_thd_for_next_query to reset THD state before
execution of a prepared statement.
Normally this should have been added to just one place, but
we have to reset thd before assigning placeholders from variables,
thus we can't do that in execute_stmt (yuck).

Manual resolve of the merge
execute crashes server": we were deleting lex->result
after each execute, but prepared statements assumed that
it's left intact.
The fix adds cleanup() method to select_result hierarchy,
so that result objects can be reused.
Plus we now need to delete result objects more wisely.
mysql-test/r/ps.result:

mysql-test/t/ps.test:
A test case for bug#5034, few followups
sql/sql_class.cc:

- implementation of cleanup() for select_result hierarchy
- select_export::send_eof was identical to
select_dump::send_eof: moved to the base class select_to_file.
- Statement::end_statement() to end lex, free items, and
delete possible select_result
sql/sql_class.h:

sql/sql_insert.cc:
- implementation of select_insert::cleanup(): currently
we always create a new instance of select_insert/
select_create on each execute.
sql/sql_lex.cc:
- with more complicated logic of freeing lex->result it's
easier to have it non-zero only if it points to a valid
result.
sql/sql_lex.h:
Now st_lex::st_lex is not empty.
sql/sql_parse.cc:
mysql_execute_command():
- delete select_result *result only if it was created in
this function.
- use end_statement() to cleanup lex and thd in the end of
each statement.
- no need to save THD::lock if this is explain. This save
apparently left from times when derived tables were
materialized here, not in open_and_lock_tables.
sql/sql_prepare.cc:
- call result->cleanup() in reset_stmt_for_execute
- now Statement is responsible for freeing its lex->result.

Instead of trying to open time zone tables during calculation of CONVERT_TZ() function
or setting of @@time_zone variable we should open and lock them with the rest of
statement's table (so we should add them to global table list) and after that use such
pre-opened tables for loading info about time zones.
mysql-test/r/timezone2.result:

sql/item_create.h:
CONVERT_TZ() now is treated as special function.
sql/item_timefunc.cc:
Item_func_convert_tz now uses list of pre-opened time zone tables instead of trying to
open them ad-hoc. Also it avoid calling of current_thd.
sql/item_timefunc.h:
Added comment describing special nature of CONVERT_TZ() function.
Optimization: Added own fix_fields() method and tz_tables member for caching pointer
to list of open time zone tables to Item_func_convert_tz class.
sql/lex.h:
CONVERT_TZ() now is treated as special function.
sql/mysql_priv.h:
Removed function which is no longer used.
sql/set_var.cc:
Now my_tz_find() accepts list of pre-opened time zone tables as last argument
and no longer needs pointer to current THD.
sql/set_var.h:
Exported sys_time_zone, which is now used in sql_yacc.yy for quick finding out if we are
setting @@time_zone variable.
sql/sql_base.cc:
Moved propagation of pointers to open tables from global list to local select lists to
open_and_lock_tables(), also added implicit usage of time zone tables as condition for
such propagation.
sql/sql_lex.cc:
Added fake_time_zone_tables_list which is used to indicate that time zone tables are
implicitly used in statement.
st_select_lex_unit::create_total_list(): if time zone tables are implicitly used in
statement add them to global tables list.
sql/sql_lex.h:
Added LEX::time_zone_tables_used member which is used to indicate that time zone tables
are implicitly used in this statement (by pointing to fake_time_zone_table_list) and
for holding pointer to those tables after they've been opened.
sql/sql_parse.cc:
We should also create global table list if statement uses time zone tables implicitly.
Added initialization of LEX::time_zone_tables_used to mysql_query_init().
sql/sql_prepare.cc:
We should also create global table list if statement uses time zone tables implicitly.
sql/sql_select.cc:
Removed functions which are no longer used.
sql/sql_yacc.yy:
CONVERT_TZ() and @@time_zone variable are handled in special way since they implicitly
use time zone tables.
sql/tztime.cc:
Fix for bug #4508 "CONVERT_TZ() function with new time zone as param crashes server".
If statement uses CONVERT_TZ() function or @@time_zone variable is set then it implicitly
uses time zone tables. We need to open and lock such tables with all other tables of
such statement.
All code responsible for opening table was removed from tz_load_from_db() and function was
renamed to tz_load_from_open_tables() (which uses list of pre-opened tables).
We also have new functions for construction and initialization of table list of time
zone tables.
my_tz_find() now always require list of pre-opened time zone tables and no longer needs
current THD. So we have to pre-open them in my_tz_init().
Also now we try to open time zone tables only if they were found during startup.
sql/tztime.h:
New function for construction of table list of time zone tables my_tz_get_table_list().
Now my_tz_find() requires list of pre-pened time zone tables instead of current thread.

by binlogging some SET ONE_SHOT CHARACTER_SETetc,
which will be enough until we have it more compact and more complete in 5.0. With the present patch,
replication will work ok between 4.1.3 master and slaves, as long as:
- master and slave have the same GLOBAL.COLLATION_SERVER
- COLLATION_DATABASE and CHARACTER_SET_DATABASE are not used
- application does not use the fact that table is created with charset of the USEd db (BUG#2326).
all of which are not too hard to fulfill.
ONE_SHOT is reserved for internal use of mysqlbinlog|mysql and works only for charsets,
so we give error if used for non-charset vars.

should contain unchanged table name, and this was not true for temporary tables which
had 'tmp-table' constant as alias. Now we are using table name as alias for such tables.
sql/sql_lex.cc:
Removed tmp_table_alias constant which is no longer used.
sql/sql_lex.h:
Removed tmp_table_alias constant which is no longer used.
sql/sql_yacc.yy:
Let us use table name instead of 'tmp-table' as alias for table being created by
CREATE TEMPORARY TABLE statement. This fixes failing temp_table.test on Darwin 7.3
since mysql_create_table() code assumes that if lower_case_names==2 then table alias
should contain unchanged table name (and now this assumtion is true but it were false
for temporary tables before...).

Fix for ORDER BY handling in GROUP_CONCAT()
Final version of patch.
Adds support for specifying of DEFAULT NOW() and/or ON UPDATE NOW()
clauses for TIMESTAMP field definition.
Current implementation allows only one such field per table and
uses several unireg types for storing info about this properties of
field. It should be replaced with better implementation when new
.frm format is introduced.
include/mysqld_error.h:
Added error codes for case when we have more than one column with NOW()
in DEFAULT or ON UPDATE clauses and for case when we are using ON UPDATE
clause with wrong type.
mysql-test/r/create.result:
Added tests for using of DEFAULT NOW() and ON UPDATE NOW() with
non-TIMESTAMP fields.
mysql-test/r/show_check.result:
Updated test results to reflect new default look of TIMESTAMP fields
in SHOW CREATE TABLE.
mysql-test/r/system_mysql_db.result:
Updated test results to reflect new default look of TIMESTAMP fields
in SHOW CREATE TABLE.
mysql-test/r/type_ranges.result:
Updated test results to reflect new default look of TIMESTAMP fields
in SHOW COLUMNS.
mysql-test/r/type_timestamp.result:
Added tests for various DEFAULT and ON UPDATE clauses for TIMESTAMP
fields definitions.
mysql-test/t/create.test:
Added tests for using of DEFAULT NOW() and ON UPDATE NOW() with
non-TIMESTAMP fields.
mysql-test/t/type_timestamp.test:
Added tests for various DEFAULT and ON UPDATE clauses for TIMESTAMP
fields definitions.
sql/field.cc:
Added support for various combinations of DEFAULT and ON UPDATE clauses
for TIMESTAMP field.
Setting TABLE::timestamp* members for TIMESTAMP fields with auto-set
option taking into account their unireg type (which corresponds to
various DEFAULT/ON UPDATE values combinations). Replaced
TABLE::time_stamp with TABLE::timestamp_default_now/on_update_now
couple moved their setup to separate method set_timestamp_offsets(),
which now is called from open_table instead of Field_timestamp cons.
sql/field.h:
Added more unireg types for handling of DEFAULT NOW() and ON UPDATE
NOW() for TIMESTAMP fields.
Fixed value corresponding to DEFAULT item for TIMESTAMP field.
sql/ha_berkeley.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_heap.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.

Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/ha_myisammrg.cc:
Now TIMESTAMP column with auto-set property could be updated during
INSERT or/and UPDATE independently.
sql/item_func.h:
We need to distinguish NOW() from other function for using in
DEFAULT and in ON UPDATE clauses.
sql/item_timefunc.h:
We need to distinguish NOW() from other function for using in
DEFAULT and in ON UPDATE clauses.
sql/mysql_priv.h:
Added parameter for ON UPDATE value to add_field_to_list() function.

sql/sql_load.cc:
Using TABLE::timestamp_default_now/on_update_now pair instead of
old TABLE::time_stamp. We don't need to restore these members
since they are set up for each statement in open_table().
sql/sql_parse.cc:
Added handling of DEFAULT NOW() and ON UPDATE NOW() clauses for
TIMESTAMP fields to add_field_to_list() function.
sql/sql_show.cc:
Added support for DEFAULT CURRENT_TIMESTAMP (aka NOW() ) and
ON UPDATE CURRENT_TIMESTAMP to SHOW CREATE TABLE and SHOW COLUMNS.
sql/sql_table.cc:
mysql_create_table() function - added check for number of TIMESTAMP
fields with auto-set values and replacing of old style TIMESTAMPs
with their newer analogs.
mysql_alter_table(): Using TABLE::timestamp_default_now/on_update_now
pair instead of old TABLE::time_stamp. We don't need to restore these
members since they are set up for each statement in open_table().
sql/sql_update.cc:
Left only setting of TABLE::timestamp_default_now/on_update_now
to 0 since they should be already set up in open_table().
sql/sql_yacc.yy:
Added support for DEFAULT NOW() and ON UPDATE NOW() in field
definitions.
sql/table.h:
Replaced TABLE::time_stamp withTABLE::timestamp_default_now/timestamp_on_update_now
pair which allows to distinguish TIMESTAMP's with various DEFAULT/ON UPDATE
clauses and optimize checks if TIMESTAMP field should be set to NOW()
in handlers.
sql/unireg.cc:
Now we are marking only TIMESTAMP fields with NOW() as default or
as on update value as special field for unireg.
This is to enable table handlers to implement online create/drop index.
It consists of some parts:
- New default handler methods in handler.h
- Split of mysql_alter_table. It decides if only one kind of
alteration is to be done (e.g. only create indexes or only drop
indexes etc.) It then calls the specialized new handler method if
the handler implements it. Otherwise it calls real_alter_table.
- The parser sets flags for each alter operation detected in a
command. These are used by mysql_alter_table for the decision.
- mysql_prepare_table is pulled out of mysql_create_table. This is
also used by mysql_create_index to prepare the key structure array
for the handler. It is also used by mysql_create_index and
mysql_drop_index to prepare a call to mysql_create_frm.
- mysql_create_frm is pulled out of rea_create_table for use by
mysql_create_index and mysql_drop_index after the index is
created/dropped.
Thanks to Antony who supplied most of the changes.
sql/handler.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New virtual handler methods with default implementation and return flags.
sql/mysql_priv.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
New function prototypes. mysql_prepare_table is pulled out of
mysql_create_table. It prepares a table structure, which is used by
mysql_create_table, mysql_create_index and mysql_drop_index.
real_alter_table is pulled out of mysql_alter_table. The latter only
looks if the requested operation can be done by specialized functions
or else calls real_alter_table, which does the real thing.
mysql_add_column and mysql_drop_colunm are for future use. They simply
call real_alter_table. mysql_create_frm is pulled out of
rea_create_table. It is called also from mysql_create_index and
mysql_drop_index after successful create/drop index.
mysql_alter_table prototype is extended by the new alter_flags argument.
sql/sql_base.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_create_index and mysql_drop_index moved to sql_table.cc.
sql/sql_lex.h:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Definitions for the new alter_flags.
sql/sql_parse.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Extend the calls to mysql_alter_table by the new alter_flags argument.
sql/sql_table.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_prepare_table is pulled out of mysql_create_table.
mysql_create_index and mysql_drop_index are changed so that they use
the new handler functions if the handler implements them.
mysql_add_column and mysql_drop_column are for future use. They simply
call real_alter_table. mysql_alter_table only decides which function
to use for the requested operation. real_alter_table implements most
of what mysql_alter_table did before.
sql/sql_yacc.yy:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
Set the alter_flags where appropriate.
sql/unireg.cc:
Worklog#1563 - Support of on-line CREATE/DROP INDEX.
mysql_create_frm is pulled out of rea_create_table.
