Problems:
- dot character was always printed as decimal point
instead of localized decimal point for short
numbers without thousands
- Item_func_format::val_str always returned values in ASCII
format,
regargless of @@character_set_connection, which in case of utf32
led to crash in debug build, or to incorrect values in release build.
Fix:
- Adding a piece of code to replace dot character to
localized decimal point in short numbers.
- Changing parent class for Item_func_format to
Item_str_ascii_func, because its val_str() implementation is heavily ASCII oriented.
was caused by change of thread state name from "Waiting for
table" to "Waiting for table metadata lock" (which has
happened as part of fix for bug 52044 "FLUSH TABLES WITH READ
LOCK and FLUSH TABLES <list> WITH READ LOCK are incompati").
on CREATE TABLE .. SELECT I_S.PART
This assert was triggered if an InnoDB table was created using
CREATE TABLE ... AS SELECT where the query used an I_S table, and
a view existed in the database. It would also be triggered for
any statement changing an InnoDB table (e.g. INSERT, UPDATE, DELETE)
which had a subquery referencing an I_S table.
The assert was triggered if open_normal_and_derived_tables() failed
and a statement transaction had been started. This will usually not
happen as tables are opened before a statement transaction is started.
However, e.g. CREATE TABLE ... AS SELECT starts a transaction in order
to insert tuples into the new table. And if the subquery references
an I_S table, all current tables and views can be opened in order to
fill the I_S table on the fly. If a view is discovered, open will fail
as it is instructed to open tables only (OPEN_TABLE_ONLY). This would
cause the assert to be triggered.
The assert was added in the patch for Bug#52044 and was therefore
not in any released versions of the server.
This patch fixes the problem by adjusting the assert to take into
consideration the possibility of tables being opened as part of
an I_S query. This is similar to what is already done for
close_tables_for_reopen().
Test case added to information_schema_inno.test.
temp table
This patch introduces two key changes in the replication's behavior.
Firstly, it reverts part of BUG#51894 which puts any update to temporary tables
into the trx-cache. Now, updates to temporary tables are handled according to
the type of their engines as a regular table.
Secondly, an unsafe mixed statement, (i.e. a statement that access transactional
table as well non-transactional or temporary table, and writes to any of them),
are written into the trx-cache in order to minimize errors in the execution when
the statement logging format is in use.
Such changes has a direct impact on which statements are classified as unsafe
statements and thus part of BUG#53259 is reverted.
Problem: a few functions did not calculate their max_length correctly.
This is an after-fix for WL#2649 Number-to-string conversions".
Fix: changing the buggy functions to calculate max_length
using fix_char_length() introduced in WL#2649,
instead of setting max_length directly

- Introducing new method fix_char_length_ulonglong(),
for the cases when length is potentially greater
than UINT_MAX32. This method removes a few
instances of duplicate code, e.g. in item_strfunc.cc.
- Setting collation in Item_copy properly. This change
fixes wrong metadata on client side in some cases, when
"binary" instead of the real character set was reported.
sql/item_cmpfunc.cc
- Using fix_char_length() and max_char_length() methods,
instead of direct access to max_length, to calculate
item length properly.
- Moving count_only_length() in COALESCE after
agg_arg_charsets_for_string_result(). The old
order was incorrect and led to wrong length
calucation in case of multi-byte character sets.

Fixing that count_only_length() didn't work
properly for multi-byte character sets.
Using fix_char_length() and max_char_length()
instead of direct access to max_length.
sql/item_strfunc.cc
- Using fix_char_length(), fix_char_length_ulonglong(),
max_char_length() instead of direct access to max_length.
- Removing wierd condition: "if (collation.collation->mbmaxlen > 0)",
which is never FALSE.
#ifdef THREAD removed from mysql.cc.

check_if_table_exists()
This assert was triggered when the server tried to load plugins
while running in embedded server mode. In embedded server mode,
check_if_table_exists() was used to check if mysql.plugin existed
so that ER_NO_SUCH_TABLE could be silently ignored.
The problem was that this check was done without acquiring a metadata
lock on mysql.plugin first. This triggered the assert.
This patch fixes the problem by removing the call to
check_if_table_exists() from plugin_load(). Instead an error handler
which traps ER_NO_SUCH_TABLE is installed before trying to open
mysql.plugin when running in embedded server mode.
No test coverage added since this assert was triggered by
existing tests running in embedded server mode.
sql/sql_base.cc:
Renamed Prelock_error_handler to No_such_table_error_handler
and moved the declaration to sql_base.h to make it usable
in plugin_load().
sql/sql_base.h:

which traps ER_NO_SUCH_TABLE during open_and_lock_tables().
Problem: Item_func_hex::val_str() returned data in ASCII format,
which did not match collation.collation pointing to my_charset_utf32_general_ci.
Fix: changing parent class of Item_func_hex to Item_str_ascii_func,
as val_str() implementation is heavily ASCII-oriented.

'CREATE TABLE IF NOT EXISTS ... SELECT' behaviour
BUG#47132, BUG#47442, BUG49494, BUG#23992 and BUG#48814 will disappear
automatically after the this patch.
BUG#55617 is fixed by this patch too.
This is the 5.5 part.
It implements:
- 'CREATE TABLE IF NOT EXISTS ... SELECT' statement will not insert
anything and binlog anything if the table already exists.
It only generate a warning that table already exists.
- A couple of test cases for the behavior changing.
Added InnoDB to the 'default' plugin group, and modified
the autoconf script so the 'default' group is actually
built by default.
(i.e ./configure.am == ./configure.am --with-plugins=default ,
instead of being ./configure.am --with-plugins=none )
'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.

which didn't fully fix the test because the order of the returned
rows was different in embedded and non-embedded version. So the only
way to fix this is to add an ORDER BY clause.
rpl_ndb.rpl_ndb_2other fails
The two regressions tests failed after WL#5349 was
pushed, since they were writted with the implicit
requirement that MyISAM is the default storage engine.
Adding --default-storage-engine=MyISAM as startup
parameter, to mimic the pre-wl#5349 situation.

Fix Bug#53761 RANGE estimation for matched rows may be 200 times different
Improve the range estimation algorithm.
Previously:
For a given level the algo knows the number of pages in the requested range
and the number of records on the leftmost and the rightmost page. Then it
assumes all pages in between contain the average between the two border pages
and multiplies this average number by the number of intermediate pages.
With this change:
Same idea, but peek a few (10) of the intermediate pages to get a better
estimate of the average number of records per page. If there are less than 10
intermediate pages then all of them will be scanned and the result will be
precise, not an estimation.
In the bug report one of the examples has a btree with a snippet of the leaf
level like this:
page1(899 records), page2(1 record), page3(1 record), page4(1 record)
so when trying to estimate, the previous algo, assumed there are average
(899+1)/2=450 records per page which went terribly wrong. With this change
page2 and page3 will be read and the exact number of records will be returned.
