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).

(offers an alternative to SELECTing any InnoDB table). Does something only for InnoDB.

bug #6515: count(distinct...) crashes the server)
In order to prevent repeated setup() call in the JOIN::make_sum_func_list(),
the code was splitted: new setup_sum_funcs() was introduced.
Note: we don't call setup_sum_funcs() in the opt_range.cc:get_best_group_min_max().
the result takes its charset/collation
attributes from the character string,
e.g. SELECT func(NULL, _latin2'string')
now returns a latin2 result. This is
done by introducing a new derivation
(aka coercibility) level DERIVATION_IGNORABLE,
which is used with Item_null.
2. 'Pure' NULL is now BINARY(0), not CHAR(0).
I.e. NULL is now more typeless.

Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

Fixed the problem of bug reports #6307 and #6460.
The reported wrong result sets were due to the fact that
the added call of the fix_fields method for the built

broke ON expression, as it removed extra AND levels
in the built condition.
It looks like that no attributes of the built condition
are needed, so we don't have to call fix_fields here.

character set with NULL, @a should be latin2
after this query sequence:
SET @a=_latin2'string';

original value assigned during the first query.
In order to do it, we don't copy charset
from the argument if the argument is NULL
