when logging is enabled.
Currently the partition engine doesn't allow log tables to
be partitioned. But this was not checked and the server crashed.
Fixed by adding a check in ALTER TABLE to disable partitioning the
log tables.
While working on the cause of the problem improved the way the log
thread structures are initialized before opening the log tables.

Bug #27816: optional
Improved initialization of the log threads before opening
the log table.
Remedies problems that arise from open_table() et. al.
depending on a correctly initialized thd.
Prerequisite for handling partitioned log tables :
they call the parser while reading the .frm file.
sql/sql_table.cc:
Bug #27816: throw an error when paritioning the log tables :
not supported by the partition engine.
When constructing the path to the original .frm file ALTER .. RENAME
was unnecessary (and incorrectly) lowercasing the whole path when not
on a case-insensitive filesystem.
This path should not be modified because of lower_case_table_names
as it is already in the correct case according to that setting.
Fixed by removing the lowercasing.
Unfortunately testing this would require running the tests on a case
sensitive filesystem in a directory that has uppercase letters.
This cannot be guaranteed in all setups so no test case added.

While executing ALTER TABLE ... PARTITION the server uses
a temporary "shadow" table to create the updated table.
This shadow table then gets renamed as the original table.
The shadow table was not prefixed with the special prefix that
marks temporary tables so it was picked up by SHOW TABLE STATUS.
Fixed by isolating the code to create the shadow table name in a
separate function and prefixing the shadow table name with the
special prefix to exclude it from the list of user tables.
See bug 18775 and WL1324 for details.

To avoid unnecessary work the mysql_alter_table function takes the
list of table fields and applies all changes to it (drops/moves/renames/etc).
Then this function compares the new list and the old one. If the changes
require only .frm to be modified then the actual data isn't copied. To detect
changes all columns attributes but names are compared. When a column has been
moved and has replaced another column with the same attributes except name
the mysql_alter_table function wrongly decides that two fields has been just
renamed. As a result the data from the moved column and from all columns
after it is not copied.
Now the mysql_alter_table function forces table data copying by setting
the need_copy_table flag when it finds a moved column. The flag is set at
the stage when the modified fields are created.
sql/sql_table.cc:
Bug#28427: Columns were renamed instead of moving by ALTER TABLE.
Now the mysql_alter_table function forces table data copying by setting
the need_copy_table flag when it finds a moved column. The flag is set at
the stage when the modified fields are created.

Added a test case for the bug#28427: Columns were renamed instead of moving by ALTER TABLE.
Problem: we may create a deadlock committing changes in the mysql_alter_table() when
LOCK_open is set. Moreover, "in some variants of the ALTER TABLE commit
happens earlier, outside of LOCK_open, in other later - inside. It's no good, a storage
engine code that is called in between could expect a consistency - either there is a
transaction or there is not".
Fix: move the commit to happen earlier and outside of the LOCK_open.

The bug was repeated on MyISAM tables, so isn't InnoDB specific.

wasn't properly updated after ALTER command. So if other thread doesn't

Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing"
Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from
stored procedure."
Bug#19733 "Repeated alter, or repeated create/drop, fails"
Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server"
Bug#24879 "Prepared Statements: CREATE TABLE (UTF8 KEY) produces a
growing key length" (this bug is not fixed 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 are not
re-execution friendly: during their operation they 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 in mysql_execute_command.
Additionally, this patch splits the part of mysql_alter_table
that analizes and rewrites information from the parser into
a separate function - mysql_prepare_alter_table, in analogy with
mysql_prepare_table, which is renamed to mysql_prepare_create_table.

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.
Get rid of Alter_info::clear() which was an attempt to save on
matches and always use Alter_info::reset().
Implement an auxiliary Alter_info::init_for_create_from_alter()
which is used in mysql_alter_table.
sql/sql_list.cc:
Implement a copy constructor of class List that makes a deep copy
of all list nodes.
sql/sql_list.h:
Implement a way to make a deep copy 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 was a bug.
Just like CREATE INDEX, DROP INDEX is currently done via complete
table rebuild and is rightfully a slow administrative statement.
sql/sql_partition.cc:
Move is_partition_management() to sql_lex.cc
Adjust code to the new Alter_info.
sql/sql_table.cc:
Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table,
mysql_prepare_table to new signatures.
Rename mysql_prepare_table to mysql_prepare_create_table. Make
sure it follows the convention and returns FALSE for success and
TRUE for error.
Move parts of mysql_alter_table to mysql_prepare_alter_table.
Move the first invokation of mysql_prepare_table from mysql_alter_table
to compare_tables, as it was needed only for the purpose
of correct comparison.
Since now Alter_info itself is created in the runtime mem root,
adjust mysql_prepare_table to always allocate memory in the
runtime memory root.
Remove dead code.
sql/sql_yacc.yy:
LEX::key_list and LEX::create_list moved to class Alter_info

Bug #23667 "CREATE TABLE LIKE is not isolated from alteration
by other connections"
Bug #18950 "CREATE TABLE LIKE does not obtain LOCK_open"
As well as:
Bug #25578 "CREATE TABLE LIKE does not require any privileges
on source table".
The first and the second bugs resulted in various errors and wrong
binary log order when one tried to execute concurrently CREATE TABLE LIKE
statement and DDL statements on source table or DML/DDL statements on its
target table.
The problem was caused by incomplete protection/table-locking against
concurrent statements implemented in mysql_create_like_table() routine.
We solve it by simply implementing such protection in proper way.
Most of actual work for 5.1 was already done by fix for bug 20662 and
preliminary patch changing locking in ALTER TABLE.
The third bug allowed user who didn't have any privileges on table create
its copy and therefore circumvent privilege check for SHOW CREATE TABLE.
This patch solves this problem by adding privilege check, which was missing.
Finally it also removes some duplicated code from mysql_create_like_table()
and thus fixes bug #26869 "TABLE_LIST::table_name_length inconsistent with
TABLE_LIST::table_name".
mysql-test/r/create-big.result:
Added test coverage for concurrency-related issues with CREATE TABLE LIKE.
mysql-test/r/create.result:
Adjusted error-code in the test case after refactoring code that
implements CREATE TABLE ... LIKE.
mysql-test/r/grant2.result:
Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges
on source table".
mysql-test/t/create-big.test:
Added test coverage for concurrency-related issues with CREATE TABLE LIKE.
mysql-test/t/create.test:
Adjusted error-code in the test case after refactoring code that
implements CREATE TABLE ... LIKE.
mysql-test/t/disabled.def:
Recent code changes ensured that CREATE TABLE LIKE statement is properly
isolated against other statements, so synchronization.test should no
longer fail (see fix for bug 20662 and preliminary patch for bug 23667
changing ALTER TABLE locking).
mysql-test/t/grant2.test:
Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges
on source table".
sql/handler.h:
Introduced new flag for HA_CREATE_INFO::options in order to be able to
distinguish CREATE TABLE ... LIKE from other types of CREATE TABLE.
sql/mysql_priv.h:
mysql_create_like_table() now takes source table name not as a
Table_ident object but as regular table list element.
sql/sql_lex.h:
Removed LEX::like_name member. Now we use special flag in
LEX::create_info::options for distinguishing CREATE TABLE ... LIKE
from other types of CREATE TABLE and store name of source table as
regular element in statement's table list.
sql/sql_parse.cc:
CREATE TABLE ... LIKE implementation now uses statement's table list
for storing information about the source table. We also use flag
in LEX::create_info.options for distinguishing it from other types
of CREATE TABLE.
Finally CREATE TABLE ... LIKE now requires the same privileges on
the source tables as SHOW CREATE TABLE. Moved this privilege check
to check_show_create_table_access() function.
sql/sql_partition.cc:
Now we use special flag in LEX::create_info::options for distinguishing
CREATE TABLE ... LIKE from other types of CREATE TABLE and store name
of source table as regular element in statement's table list.
sql/sql_table.cc:
mysql_create_like_table():
- Commented and cleaned-up a bit code which is responsible for achieving
isolation from concurrent statements. Most of actual work was done by
fix for bug 20662 and preliminary patch changing locking locking in
ALTER TABLE, so here we do minor things like relaxing locking on
source table (we don't need lock on it, to have it open is enough) and
adjusting code to make it more friendly against code implementing I_S.
- Get rid of duplicated code related to source database/table name
handling. All these operations are already done in
st_select_lex::add_table_to_list(), so we achieve the same effect
by including source table into the statement's table list.

this patch as well.

sql/sql_table.cc:
mysql_create_like_table():
- Provided proper protection from concurrent statements.
This is achieved by keeping name-lock on the source table and holding
LOCK_open mutex during whole operation. This gives protection against
concurrent DDL on source table. Also holding this mutex makes copying
of .frm file, call to ha_create_table() and binlogging atomic against
concurrent DML and DDL operations on target table.
- Get rid of duplicated code related to source database/table name
handling. All these operations are already done in
st_select_lex::add_table_to_list(), so we achieve the same effect

mode.
When a new DATE/DATETIME field without default value is being added by the
ALTER TABLE the '0000-00-00' value is used as the default one. But it wasn't
checked whether such value was allowed by the set sql mode. Due to this
'0000-00-00' values was allowed for DATE/DATETIME fields even in the
NO_ZERO_DATE mode.
Now the mysql_alter_table() function checks whether the '0000-00-00' value
is allowed for DATE/DATETIME fields by the set sql mode.
The new error_if_not_empty flag is used in the mysql_alter_table() function
to indicate that it should abort if the table being altered isn't empty.
The new new_datetime_field field is used in the mysql_alter_table() function
for error throwing purposes.
The new error_if_not_empty parameter is added to the copy_data_between_tables()
function to indicate the it should return error if the source table isn't empty.

and invalidation in the most general case (non-temporary table and
not simple RENAME or ENABLE/DISABLE KEYS or partitioning command).
See comment for sql/sql_table.cc for more information.
These changes are prerequisite for 5.1 version of fix for bug #23667
"CREATE TABLE LIKE is not isolated from alteration by other connections"
mysql-test/include/mix1.inc:

mysql-test/t/alter_table.test:

sql/mysql_priv.h:
Made functions reopen_table() and close_handle_and_leave_table_as_lock()
available outside of sql_base.cc file.
Changed close_data_tables() in such way that after closing handler
for the table it leaves TABLE object for it in table cache not as
placeholder for ordinary name-lock but as placeholder for an exclusive
name-lock. Renamed this routine to close_data_files_and_morph_locks().
sql/sql_base.cc:
Made functions reopen_table() and close_handle_and_leave_table_as_lock()
available outside of sql_base.cc file.
Changed close_data_tables() in such way that after closing handler
for the table it leaves TABLE object for it in table cache not as
placeholder for ordinary name-lock but as placeholder for an exclusive
name-lock. Renamed this routine to close_data_files_and_morph_locks().
Also adjusted it so it can work properly not only in LOCK TABLES mode.
sql/sql_table.cc:
Changed the way in which ALTER TABLE implementation handles table
locking and invalidation in the most general case (non-temporary table
and not simple RENAME or ENABLE/DISABLE KEYS or partitioning command)
Now after preparing new version of the table we:
1) Wait until all other threads close old version of table.
2) Close instances of table open by this thread and replace them
with exclusive name-locks.
3) Rename the old table to a temp name, rename the new one to the
old name.
4) If we are under LOCK TABLES and don't do ALTER TABLE ... RENAME
we reopen new version of table.
5) Write statement to the binary log.
6) If we are under LOCK TABLES and do ALTER TABLE ... RENAME we
remove name-locks from list of open tables and table cache.
7) If we are not not under LOCK TABLES we rely on close_thread_tables()
call to remove name-locks from table cache and list of open table.
Such approach:
a) Eliminates possibility for concurrent statement to sneak in and get
access to the new version of the table before ALTER TABLE gets logged
into binary log.
b) Ensures that ALTER TABLE behaves under LOCK TABLES in the same way
on all platforms and for all engines (in 5.0 this was not true)
c) Preserves nice invariant that if table is open in some connection
there is a guarantee that .FRM file for this table exists and is
properly named.
