'CREATE TABLE IF NOT EXISTS ... SELECT' behaviour
BUG#55474, BUG#55499, BUG#55598, BUG#55616 and BUG#55777 are fixed
in this patch too.
This is the 5.1 part.
It implements:
- if the table exists, binlog two events: CREATE TABLE IF NOT EXISTS
and INSERT ... SELECT
- Insert nothing and binlog nothing on master if the existing object
is a view. It only generates a warning that table already exists.
mysql-test/r/trigger.result:
Ather this patch, 'CREATE TABLE IF NOT EXISTS ... SELECT' will not
insert anything if the creating table already exists and is a view.
sql/sql_class.h:
Declare virtual function write_to_binlog() for select_insert.
It's used to binlog 'create select'
sql/sql_insert.cc:
Implement write_to_binlog();
Use write_to_binlog() instead of binlog_query() to binlog the statement.
if the table exists, binlog two events: CREATE TABLE IF NOT EXISTS
and INSERT ... SELECT
sql/sql_lex.h:
Declare create_select_start_with_brace and create_select_pos.
They are helpful for binlogging 'create select'
sql/sql_parse.cc:
Do nothing on master if the existing object is a view.
sql/sql_yacc.yy:
Record the relative postion of 'SELECT' in the 'CREATE ...SELECT' statement.
Record whether there is a '(' before the 'SELECT' clause.
INSERT IGNORE ... SELECT ... UNION SELECT ...
This assert was triggered by INSERT IGNORE ... SELECT. The assert checks that a
statement either sends OK or an error to the client. If the bug was triggered
on release builds, it caused OK to be sent to the client instead of the correct
error message (in this case ER_FIELD_SPECIFIED_TWICE).
The reason the assert was triggered, was that lex->no_error was set to TRUE
during JOIN::optimize() because of IGNORE. This causes all errors to be ignored.
However, not all errors can be ignored. Some, such as ER_FIELD_SPECIFIED_TWICE
will cause the INSERT to fail no matter what. But since lex->no_error was set,
the critical errors were ignored, the INSERT failed and neither OK nor the
error message was sent to the client.
This patch fixes the problem by temporarily turning off lex->no_error in
places where errors cannot be ignored during processing of INSERT ... SELECT.
Test case added to insert.test.
Fixed some wrong test cases

This was triggered by innodb.innodb_multi_update, where we had a static length row without nulls and xtradb didn't fill in the delete-marker byte
include/my_bitmap.h:
Added prototype for bitmap_union_is_set_all()
mysys/my_bitmap.c:
Added function to check if union of two bit maps covers all bits.
sql/mysql_priv.h:
Updated protype for compare_record()
sql/sql_insert.cc:
Send to compare_record() flag if all fields are used.
sql/sql_select.cc:
Set share->null_bytes_for_compare.
sql/sql_update.cc:
In compare_record() don't use the fast cmp_record() (which is basically memcmp) if we don't know that all fields exists.
Don't compare the null_bytes if there is no data there.
sql/table.cc:
Store in share->null_bytes_for_compare the number of bytes that has null or bit fields (but not delete marker)
Store in can_cmp_whole_record if we can use memcmp() (assuming all rows are read) to compare rows in compare_record()
sql/table.h:
Added two elements in table->share to speed up checking how updated rows can be compared.
A CREATE...SELECT that fails is written to the binary log if a non-transactional
statement is updated. If the logging format is ROW, the CREATE statement and the
changes are written to the binary log as distinct events and by consequence the
created table is not rolled back in the slave.
In this patch, we opted to let the slave goes out of sync by not writting to the
binary log the CREATE statement. We do this by simply reseting the binary log's
cache.
mysql-test/suite/rpl/r/rpl_drop.result:
Added a test case.
mysql-test/suite/rpl/t/rpl_drop.test:
Added a test case.
sql/log.cc:
Introduced a function to clean up the cache.
sql/log.h:
Introduced a function to clean up the cache.
sql/sql_insert.cc:
Cleaned up the binary log cache if a CREATE...SELECT fails.
For queries with order by clauses that employed filesort usage of
virtual column references in select lists could trigger assertion
failures. It happened because a wrong vcol_set bitmap was used for
filesort. It turned out that filesort required its own vcol_set bitmap.
Made management of the vcol_set bitmaps similar to the management
of the read_set and write_set bitmaps.
There were two problems that caused wrong results reported with this bug.
1. In some cases stored(persistent) virtual columns were not marked
in the write_set and in the vcol_set bitmaps.
2. If the list of fields in an insert command was empty then the values of
the stored virtual columns were set to default.
To fix the first problem the function st_table::mark_virtual_columns_for_write
was modified. Now the function has a parameter that says whether the virtual
columns are to be marked for insert or for update.
To fix the second problem a special handling of empty insert lists is
added in the function fill_record().

sql/sql_class.cc:
Fixed wrong output for high end machines in outfile_loaddata.
(Problem was that ER_TRUNCATED_WRONG_VALUE_FOR_FIELD expects ulong, not ulonglong)
sql/sql_insert.cc:
Ensure that if we get a lock problem with delayed_insert, the error is logged.
The problem was a "self-deadlock" if the connection issuing INSERT DELAYED
had both the global read lock (FLUSH TABLES WITH READ LOCK) and LOCK TABLES
mode active. The table being inserted into had to be different from the
table(s) locked by LOCK TABLES.
For INSERT DELAYED, the connection thread waits until the handler thread has
opened and locked its table before returning. But since the global read lock
was active, the handler thread would be unable to lock and would wait for the
global read lock to go away.
So the handler thread would be waiting for the connection thread to release
the global read lock while the connection thread was waiting for the handler
thread to lock the table. This gave a "self-deadlock" (same connection,
different threads).
The deadlock would only happen if we also had LOCK TABLES mode since the
INSERT otherwise will try to get protection against global read lock before
starting the handler thread. It will then notice that the global read lock
is owned by the same connection and report ER_CANT_UPDATE_WITH_READLOCK.
This patch removes the deadlock by reporting ER_CANT_UPDATE_WITH_READLOCK
also if we are inside LOCK TABLES mode.
Test case added to delayed.test.
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.
This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.
This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.

Implemented the server infrastructure for the fix:
1. Added a function LEX_STRING *thd_query_string(THD) to return
a LEX_STRING structure instead of char *.
This is the function that must be called in innodb instead of
thd_query()
2. Did some encapsulation in THD : aggregated thd_query and
thd_query_length into a LEX_STRING and made accessor and mutator
methods for easy code updating.
3. Updated the server code to use the new methods where applicable.
* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
newer testsuite). They are expected to go after mergning with the latest
xtradb.
name as existing view
When trying to create a table with the same name as existing view with
join, mysql server crashes.
The problem is when create table is issued with the same name as view, while
verifying with the existing tables, we assume that base table object is
created always.
In this case, since it is a view over multiple tables, we don't have the
mysql derived table object.
Fixed the logic which checks if there is an existing table to not to assume
that table object is created when the base table is view over multiple
tables.
