Allow index on 'CHAR(0) NULL' columns
Fixed error in Maria when using table with only CHAR(0) fields Fixed valgrind warning BitKeeper/etc/ignore: added storage/maria/maria_dump_log mysql-test/r/maria.result: Testing of table with char(0) mysql-test/t/maria.test: Testing of table with char(0) sql/sql_table.cc: Allow index on 'CHAR(0) NULL' columns storage/maria/ma_create.c: Allow creation of table with 0 record data (for example CHAR(0)) storage/maria/ma_pagecrc.c: Fixed valgrind warning |

An assertion added (transaction must be re-enabled before end of
top-level statement) and fixes for the bugs it finds.
Fix for non-serious Valgrind warning.
sql/sql_insert.cc:
When CREATE TABLE IF NOT EXISTS finds the table already exists,
'table' is the existing table. So if that table is temporary we don't
re-enable transactions which is a bug.
sql/sql_parse.cc:
verify that at the end of each top-statement transactions have
been re-enabled. Does not apply to substatements (consider
CREATE TABLE t1 SELECT stored_func() : the substatements inside
stored_func() run with transaction disabled).
I am not putting the assertion into ha_external_lock(F_UNLCK) because
performance schema tables get closed in the middle of a statement
sometimes while transaction is disabled.
sql/sql_table.cc:
copy_data_between_tables() forgot to clean-up several things in error
conditions (ha_enable_transaction(), free-ing 'copy', etc) as found
by the assertion added to sql_parse.cc.
storage/maria/ha_maria.cc:
Comment
storage/maria/ma_blockrec.c:
fix for Valgrind warning: a temporary table was created, a blob
page of its was flushed to disk and had random bytes in the checksum
area ("write of uninitialized bytes in pwrite")
storage/maria/ma_pagecrc.c:

WL#3072 - Maria Recovery
* to honour WAL we now force the whole log when flushing a bitmap page. * ability to intentionally crash in various places for recovery testing * bugfix (dirty pages list found in checkpoint record was ignored) * smaller checkpoint record * misc small cleanups and comments mysql-test/include/maria_empty_logs.inc: maria-purge.test creates ~11 logs, remove them all mysql-test/r/maria-recovery-bitmap.result: result is good; without the _ma_bitmap_get_log_address() call, we got check error Bitmap at 0 has pages reserved outside of data file length mysql-test/r/maria-recovery.result: result update mysql-test/t/maria-recovery-bitmap.test: enable test of "bitmap-flush should flush whole log otherwise corrupted data file (bitmap ahead of data pages)". mysql-test/t/maria-recovery.test: test of checkpoint sql/sql_table.cc: comment storage/maria/ha_maria.cc: _ma_reenable_logging_for_table() now includes file->trn=0. At the end of repair() we don't need to re-enable logging, it is done already by caller (like copy_data_between_tables()); it sounds strange that this function could decide to re-enable, it should be up to caller who knows what other operations it plans. Removing this line led to assertion failure in maria_lock_database(F_UNLCK), fixed by removing the assertion: maria_lock_database() is here called in a context where F_UNLCK does not make the table visible to others so assertion is excessive, and external_lock() is already designed to honour the asserted condition. Ability to crash at the end of bulk insert when indices have been enabled. storage/maria/ma_bitmap.c: Better use pagecache_file_init() than set pagecache callbacks directly; and a new function to set those callbacks for bitmap so that we can reuse it. _ma_bitmap_get_log_address() is a pagecache get_log_address callback which causes the whole log to be flushed when a bitmap page is flushed by the page cache. This was required by WAL. storage/maria/ma_blockrec.c: get_log_address pagecache callback for data (non bitmap) pages: just reads the LSN from the page's content, like was hard-coded before in ma_pagecache.c. storage/maria/ma_blockrec.h: functions which need to be exported storage/maria/ma_check.c: create_new_data_handle() can be static. Ability to crash after rebuilding the index in OPTIMIZE, in REPAIR. my_lock() implemented already. storage/maria/ma_checkpoint.c: As MARIA_SHARE* is now accessible to pagecache_collect_changed_blocks_LSN(), we don't need to store kfile/dfile descriptors in checkpoint record, 2-byte-id of the table plus one byte to say if this is data or index file is enough. So we go from 4+4 bytes per table down to 2+1. storage/maria/ma_commit.c: removing duplicate functions (see _ma_tmp_disable_logging_for_table()) storage/maria/ma_extra.c: Monty fixed storage/maria/ma_key_recover.c: comment storage/maria/ma_locking.c: Sometimes other code does funny things with maria_lock_database(), like ha_maria::repair() calling it at start and end without going through ha_maria::external_lock(). So it happens that maria_lock_database() is called with now_transactional!=born_transactional. storage/maria/ma_loghandler.c: update to new prototype storage/maria/ma_open.c: set_data|index_pagecache_callbacks() need to be exported as they are now called when disabling/enabling transactionality. storage/maria/ma_pagecache.c: Removing PAGE_LSN_OFFSET, as much of the code relies on it being 0 anyway (let's not give impression we can just change this constant). When flushing a page to disk, call the get_log_address callback to know up to which LSN the log should be flushed. As we now can access MARIA_SHARE* we can know share->id and store it into the checkpoint record; we thus go from 4 bytes per dirty page to 2+1. storage/maria/ma_pagecache.h: get_log_address callback storage/maria/ma_panic.c: No reason to reset pagecache callbacks in HA_PANIC_READ: all we do is reopen files if they were closed; callbacks should be in place already as 'info' exists; we just want to modify the file descriptors, not the full PAGECACHE_FILE structure. If we open data file and it was closed, share->bitmap.file needs to be set. Note that the modified code is disabled anyway. storage/maria/ma_recovery.c: Checkpoint record does not contain kfile/dfile descriptors anymore so code can be simplified. Hash key in all_dirty_pages is not made from file_descriptor & pageno anymore, but index_or_data & table-short-id & pageno. If a table's create_rename_lsn is higher than record's LSN, we skip the table and don't fail if it's corrupted (because the LSNs say that we don't have to look at this table). If a table is skipped (for example due to create_rename_lsn), its UNDOs still cause undo_lsn to advance; this is so that if later we notice the transaction has to rollback we fail (as table should not be skipped in this case). Fixing a bug: the dirty_pages list was never used, because the LSN below which it was used was the minimum rec_lsn of dirty pages! It is now the min(checkpoint_start_log_horizon, min(trn's rec_lsn)). When we disable/reenable transactionality, we modify pagecache callbacks (needed for example for get_log_address: changing share->page_type is not enough anymore). storage/maria/ma_write.c: 'records' and 'checksum' are protected: they are updated under log's mutex in write-hooks when UNDO is written. storage/maria/maria_chk.c: remove use of duplicate functions. storage/maria/maria_def.h: set_data|index_pagecache_callbacks() need to be exported; _ma_reenable_logging_for_table() changes to a real function. storage/maria/unittest/ma_pagecache_consist.c: new prototype storage/maria/unittest/ma_pagecache_single.c: new prototype storage/maria/unittest/ma_test_loghandler_pagecache-t.c: new prototype |

A pre-requisite for the fix for Bug#12713 "Error in a stored function
called from a SELECT doesn't cause ROLLBACK of state"
Make private all class handler methods (PSEA API) that may modify
data. Introduce and deploy public ha_* wrappers for these methods in
all sql/.
This necessary to keep track of all data modifications in sql/,
which is in turn necessary to be able to optimize two-phase
commit of those transactions that do not modify data.
sql/ha_partition.cc:
Class ha_partition is no longer a friend of class handler.
Use the public handler interface (handler::ha_ methods) for partition
operations.
Remove unnecessary casts from char[] to const char *.ppзи выафвыаafa
sql/handler.cc:
Function ha_create_table() is no longer a friend of class handler.
Use public handler::change_table_ptr() to access private members.
This fixes a subtle bug (no test case in the test suite) when a
deletion error occurs inside one partition of a partitioned engine.
The old code would crash in handler::print_error() in this case.
Implement the newly introduced public ha_* wrappers of the private
virtual handler methods.
sql/handler.h:
Introduce ha_* wrappers to all class handler methods that may
modify data. This is necessary to be able to keep track of
data modifying operations of class handler and optimize read-only
transactions.
sql/item_sum.cc:
delete_all_rows -> ha_delete_all_rows
sql/sql_base.cc:
Use the new public wrappers.
sql/sql_delete.cc:
delete_all_rows -> ha_delete_all_rows
sql/sql_partition.cc:
Use the new public wrappers.
sql/sql_select.cc:
delete_all_rows -> ha_delete_all_rows
delete_table -> ha_delete_table
disabe_indexes -> ha_disable_idnexes
sql/sql_show.cc:
delete_all_rows -> ha_delete_all_rows
sql/sql_table.cc:
Use the public wrappers for class handler DDL methods.
All methods which may change handler data are now accessed via a public
wrapper.
sql/sql_union.cc:
delete_all_rows -> ha_delete_all_rows
{enable,disable}_indexes -> ha_{enable,disable}_indexes

Make handler::{write,delete,update}_row private. It's critical
that the entire server uses their public ha_* counterparts instead, since only then we can ensure proper tracing of these calls that is necessary for Bug#12713. A pre-requisite for Bug#12713 "Error in a stored function called from a SELECT doesn't cause ROLLBACK of statem" sql/ha_partition.cc: Use ha_write_row, ha_update_row, ha_delete_row instead of now-private write_row, update_row, delete_row. In future ha_* calls will contain more than just a call to the binary log, so it's essential they are used consistently everywhere in the server. Disable the undesired effect of double binary logging of changes to partitioned tables with tmp_disable_binlog. sql/handler.h: Make write_row, update_row, delete_row private. It's critical that the entire code base uses ha_write_row, ha_update_row, ha_delete_row instead -- in future, ha_* counterparts will have more common functionality than just a call to the binary log. sql/sql_select.cc: Use ha_write_row, ha_update_row, ha_delete_row instead of write_row, update_row, delete_row respectively. The change affects the join execution code that works with an intermediate internal temporary table. Do not disable binary logging, since it's unnecessary - temporary tables are not replicated by row level replication. sql/sql_table.cc: Use ha_write_row in copy_data_between_tables - the function that writes data from the original table to a temporary copy when executing ALTER TABLE. Do not disable binary logging since temporary tables are not replicated by row level replication anyway. |

Bug#32395 Alter table under a impending global read lock causes a server crash
The problem is that some DDL statements (ALTER TABLE, CREATE TRIGGER, FLUSH TABLES, ...) when under LOCK TABLES need to momentarily drop the lock, reopen the table and grab the write lock again (using reopen_tables). When grabbing the lock again, reopen_tables doesn't pass a flag to mysql_lock_tables in order to ignore the impending global read lock, which causes a assertion because LOCK_open is being hold. Also dropping the lock must not signal to any threads that the table has been relinquished (related to the locking/flushing protocol). The solution is to correct the way the table is reopenned and the locks grabbed. When reopening the table and under LOCK TABLES, the table version should be set to 0 so other threads have to wait for the table. When grabbing the lock, any other flush should be ignored because it's theoretically a atomic operation. The chosen solution also fixes a potential discrepancy between binlog and GRL (global read lock) because table placeholders were being ignored, now a FLUSH TABLES WITH READ LOCK will properly for table with open placeholders. It's also important to mention that this patch doesn't fix a potential deadlock if one uses two GRLs under LOCK TABLES concurrently. mysql-test/r/lock_multi.result: Add test case result for Bug#32395 mysql-test/r/trigger_notembedded.result: Add test case result for Bug#32395 mysql-test/t/lock_multi.test: Add test case for Bug#32395 mysql-test/t/trigger_notembedded.test: Enable test case for Bug#32395 sql/ha_ndbcluster.cc: Update close_cached_tables usage. sql/ha_ndbcluster_binlog.cc: Update close_cached_tables usage. sql/mysql_priv.h: Update close_cache_tables prototype. sql/set_var.cc: Update close_cached_tables usage and set flag to wait for tables with placeholders.

Bug#12713 "Error in a stored function called from a SELECT doesn't
cause ROLLBACK of statement", part 1. Review fixes.
Do not send OK/EOF packets to the client until we reached the end of
the current statement.
This is a consolidation, to keep the functionality that is shared by all
SQL statements in one place in the server.
Currently this functionality includes:
- close_thread_tables()
- log_slow_statement().
After this patch and the subsequent patch for Bug#12713, it shall also include:
- ha_autocommit_or_rollback()
- net_end_statement()
- query_cache_end_of_result().
In future it may also include:
- mysql_reset_thd_for_next_command().
include/mysql_com.h:
Rename now unused members of NET: no_send_ok, no_send_error, report_error.
These were server-specific variables related to the client/server
protocol. They have been made obsolete by this patch.
Previously the same members of NET were used to store the error message
both on the client and on the server.
The error message was stored in net.last_error (client: mysql->net.last_error,
server: thd->net.last_error).
The error code was stored in net.last_errno (client: mysql->net.last_errno,
server: thd->net.last_errno).
The server error code and message are now stored elsewhere
(in the Diagnostics_area), thus NET members are no longer used by the
server.
Rename last_error to client_last_error, last_errno to client_last_errno
to avoid potential bugs introduced by merges.
include/mysql_h.ic:
Update the ABI file to reflect a rename.
Renames do not break the binary compatibility.
libmysql/libmysql.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
This is necessary to ensure no unnoticed bugs introduced by merged
changesets.
Remove net.report_error, net.no_send_ok, net.no_send_error.
libmysql/manager.c:
Rename net.last_errno to net.client_last_errno.
libmysqld/lib_sql.cc:
Rename net.last_errno to net.client_last_errno.
Update the embedded implementation of the client-server protocol to
reflect the refactoring of protocol.cc.
libmysqld/libmysqld.c:
Rename net.last_errno to net.client_last_errno.
mysql-test/r/events.result:
Update to reflect the change in mysql_rm_db(). Now we drop stored
routines and events for a given database name only if there
is a directory for this database name. ha_drop_database() and
query_cache_invalidate() are called likewise.
Previously we would attempt to drop routines/events even if database
directory was not found (it worked, since routines and events are stored
in tables). This fixes Bug 29958 "Weird message on DROP DATABASE if mysql.proc
does not exist".
The change was done because the previous code used to call send_ok()
twice, which led to an assertion failure when asserts against it were
added by this patch.
mysql-test/r/grant.result:
Fix the patch for Bug 16470, now FLUSH PRIVILEGES produces an error
if mysql.procs_priv is missing.
This fixes the assert that send_ok() must not called after send_error()
(the original patch for Bug 16470 was prone to this).
mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result:
Produce a more detailed error message.
mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result:
Produce a more detailed error message.
mysql-test/t/grant.test:
Update the test, now FLUSH PRIVILEGES returns an error if mysql.procs_priv
is missing.
server-tools/instance-manager/mysql_connection.cc:
Rename net.last_errno to net.client_last_errno.
sql/ha_ndbcluster_binlog.cc:
Add asserts.
Use getters to access statement status information.
Add a comment why run_query() is broken. Reset the diagnostics area
in the end of run_query() to fulfill the invariant that the diagnostics_area
is never assigned twice per statement (see the comment in the code
when this can happen). We still do not clear thd->is_fatal_error and
thd->is_slave_error, which may lead to bugs, I consider the whole affair
as something to be dealt with separately.
sql/ha_partition.cc:
fatal_error() doesn't set an error by itself. Perhaps we should
remove this method altogether and instead add a flag to my_error
to set thd->is_fatal_error property.
Meanwhile, this change is a part of inspection made to the entire source
code with the goal to ensure that fatal_error()
is always accompanied by my_error().
sql/item_func.cc:
There is no net.last_error anymore. Remove the obsolete assignment.
sql/log_event.cc:
Use getters to access statement error status information.
sql/log_event_old.cc:
Use getters to access statement error status information.
sql/mysqld.cc:
Previously, if a continue handler for an error was found, my_message_sql()
would not set an error in THD. Since the current statement
must be aborted in any case, find_handler() had a hack to assign
thd->net.report_error to 1.
Remove this hack. Set an error in my_message_sql() even if the continue
handler is found. The error will be cleared anyway when the handler
is executed. This is one action among many in this patch to ensure the
invariant that whenever thd->is_error() is TRUE, we have a message in
thd->main_da.message().
sql/net_serv.cc:
Use a full-blown my_error() in net_serv.cc to report an error,
instead of just setting net->last_errno. This ensures the invariant that
whenever thd->is_error() returns TRUE, we have a message in
thd->main_da.message().
Remove initialization of removed NET members.
sql/opt_range.cc:
Use my_error() instead of just raising thd->net.report_error.
This ensures the invariant that whenever thd->is_error() returns TRUE,
there is a message in thd->main_da.message().
sql/opt_sum.cc:
Move invocation of fatal_error() right next to the place where
we set the error message. That makes it easier to track that whenever
fatal_error() is called, there is a message in THD.
sql/protocol.cc:
Rename send_ok() and send_eof() to net_send_ok() and net_send_eof()
respectively. These functions write directly to the network and are not
for use anywhere outside the client/server protocol code.
Remove the code that was responsible for cases when either there is
no error code, or no error message, or both.
Instead the calling code ensures that they are always present. Asserts
are added to enforce the invariant.
Instead of a direct access to thd->server_status and thd->total_warn_count
use function parameters, since these from now on don't always come directly
from THD.
Introduce net_end_statement(), the single-entry-point replacement API for
send_ok(), send_eof() and net_send_error().
Implement Protocol::end_partial_result_set to use in select_send::abort()
when there is a continue handler.
sql/protocol.h:
Update declarations.
sql/repl_failsafe.cc:
Use getters to access statement status information in THD.
Rename net.last_error to net.client_last_error.
sql/rpl_record.cc:
Set an error message in prepare_record() if there is no default
value for the field -- later we do print this message to the client.
sql/rpl_rli.cc:
Use getters to access statement status information in THD.
sql/slave.cc:
In create_table_from_dump() (a common function that is used in
LOAD MASTER TABLE SQL statement and COM_LOAD_MASTER_DATA), instead of hacks
with no_send_ok, clear the diagnostics area when mysql_rm_table() succeeded.
Update has_temporary_error() to work correctly when no error is set.
This is the case when Incident_log_event is executed: it always returns
an error but does not set an error message.
Use getters to access error status information.
sql/sp_head.cc:
Instead of hacks with no_send_error, work through the diagnostics area
interface to suppress sending of OK/ERROR packets to the client.
Move query_cache_end_of_result before log_slow_statement(), similarly
to how it's done in dispatch_command().
sql/sp_rcontext.cc:
Remove hacks with assignment of thd->net.report_error, they are not
necessary any more (see the changes in mysqld.cc).
sql/sql_acl.cc:
Use getters to access error status information in THD.
sql/sql_base.cc:
Access thd->main_da.sql_errno() only if there is an error. This fixes
a bug when auto-discovery, that was effectively disabled under pre-locking.
sql/sql_binlog.cc:
Remove hacks with no_send_ok/no_send_error, they are not necessary
anymore: the caller is responsible for network communication.
sql/sql_cache.cc:
Disable sending of OK/ERROR/EOF packet in the end of dispatch_command
if the response has been served from the query cache. This raises the
question whether we should store EOF packet in the query cache at all,
or generate it anew for each statement (we should generate it anew), but
this is to be addressed separately.
sql/sql_class.cc:
Implement class Diagnostics_area. Please see comments in sql_class.h
for details.
Fix a subtle coding mistake in select_send::send_data: when on slave,
an error in Item::send() was ignored.
The problem became visible due to asserts that the diagnostics area is
never double assigned.
Remove initialization of removed NET members.
In select_send::abort() do not call select_send::send_eof(). This is
not inheritance-safe. Even if a stored procedure continue handler is
found, the current statement is aborted, not succeeded.
Instead introduce a Protocol API to send the required response,
Protocol::end_partial_result_set().
This simplifies implementation of select_send::send_eof(). No need
to add more asserts that there is no error, there is an assert inside
Diagnostics_area::set_ok_status() already.
Leave no trace of no_send_* in the code.
sql/sql_class.h:
Declare class Diagnostics_area.
Remove the hack with no_send_ok from
Substatement_state.
Provide inline implementations of send_ok/send_eof.
Add commetns.
sql/sql_connect.cc:
Remove hacks with no_send_error.
Since now an error in THD is always set if net->error, it's not necessary
to check both net->error and thd->is_error() in the do_command loop.
Use thd->main_da.message() instead of net->last_errno.
Remove the hack with is_slave_error in sys_init_connect. Since now we do not
reset the diagnostics area in net_send_error (it's reset at the beginning
of the next statement), we can access it safely even after
execute_init_command.
sql/sql_db.cc:
Update the code to satisfy the invariant that the diagnostics area is never
assigned twice.
Incidentally, this fixes Bug 29958 "Weird message on DROP DATABASE if
mysql.proc does not exist".
sql/sql_delete.cc:
Change multi-delete to abort in abort(), as per select_send protocol.
Fixes the merge error with the test for Bug 29136
sql/sql_derived.cc:
Use getters to access error information.
sql/sql_insert.cc:
Use getters to access error information.
sql-common/client.c:
Rename last_error to client_last_error, last_errno to client_last_errno.
sql/sql_parse.cc:
Remove hacks with no_send_error. Deploy net_end_statement().
The story of COM_SHUTDOWN is interesting. Long story short, the server
would become on its death's door, and only no_send_ok/no_send_error assigned
by send_ok()/net_send_error() would hide its babbling from the client.
First of all, COM_QUIT does not require a response. So, the comment saying
"Let's send a response to possible COM_QUIT" is not only groundless
(even mysqladmin shutdown/mysql_shutdown() doesn't send COM_QUIT after
COM_SHUTDOWN), it's plainly incorrect.
Secondly, besides this additional 'OK' packet to respond to a hypothetical
COM_QUIT, there was the following code in dispatch_command():
if (thd->killed)
thd->send_kill_message();
if (thd->is_error()
net_send_error(thd);
This worked out really funny for the thread through which COM_SHUTDOWN
was delivered: we would get COM_SHUTDOWN, say okay, say okay again,
kill everybody, get the kill signal ourselves, and then attempt to say
"Server shutdown in progress" to the client that is very likely long gone.
This all became visible when asserts were added that the Diagnostics_area
is not assigned twice.
Move query_cache_end_of_result() to the end of dispatch_command(), since
net_send_eof() has been moved there. This is safe, query_cache_end_of_result()
is a no-op if there is no started query in the cache.
Consistently use select_send interface to call abort() or send_eof()
depending on the operation result.
Remove thd->fatal_error() from reset_master(), it was a no-op.
in hacks with no_send_error woudl save us
from complete breakage of the client/server protocol.
Consistently use select_send::abort() whenever there is an error,
and select_send::send_eof() in case of success.
The issue became visible due to added asserts.
sql/sql_partition.cc:
Always set an error in THD whenever there is a call to fatal_error().
sql/sql_prepare.cc:

Remove the unnecessary juggling with the protocol in
Select_fetch_protocol_binary::send_eof(). EOF packet format is

Bug#23713 LOCK TABLES + CREATE TRIGGER + FLUSH TABLES WITH READ LOCK = deadlock
This bug is actually two bugs in one, one of which is CREATE TRIGGER under LOCK TABLES and the other is CREATE TRIGGER under LOCK TABLES simultaneous to a FLUSH TABLES WITH READ LOCK (global read lock). Both situations could lead to a server crash or deadlock. The first problem arises from the fact that when under LOCK TABLES, if the table is in the set of locked tables, the table is already open and it doesn't need to be reopened (not a placeholder). Also in this case, if the table is not write locked, a exclusive lock can't be acquired because of a possible deadlock with another thread also holding a (read) lock on the table. The second issue arises from the fact that one should never wait for a global read lock if it's holding any locked tables, because the global read lock is waiting for these tables and this leads to a circular wait deadlock. The solution for the first case is to check if the table is write locked and upgraded the write lock to a exclusive lock and fail otherwise for non write locked tables. Grabbin the exclusive lock in this case also means to ensure that the table is opened only by the calling thread. The second issue is partly fixed by not waiting for the global read lock if the thread is holding any locked tables. The second issue is only partly addressed in this patch because it turned out to be much wider and also affects other DDL statements.

Bug#31479 Bad lock interaction if CREATE TABLE LIKE is killed
Kill of a CREATE TABLE source_table LIKE statement waiting for a name-lock on the source table causes a bad lock interaction. The mysql_create_like_table() has a bug that if the connection is killed while waiting for the name-lock on the source table, it will jump to the wrong error path and try to unlock the source table and LOCK_open, but both weren't locked. The solution is to simple return when the name lock request is killed, it's safe to do so because no lock was acquired and no cleanup is needed. Original bug report also contains description of other problems related to this scenario but they either already fixed in 5.1 or will be addressed separately (see bug report for details). mysql-test/r/lock_multi.result: Add test case result for Bug#31479 mysql-test/t/lock_multi.test: Add test case for Bug#31479 sql/sql_table.cc: Rerturn TRUE when the lock gets killed. |

Bug#31397 Inconsistent drop table behavior of handler tables.
The problem is that DROP TABLE and other DDL statements failed to automatically close handlers associated with tables that were marked for reopen (FLUSH TABLES). The current implementation fails to properly discard handlers of dropped tables (that were marked for reopen) because it searches on the open handler tables list and using the current alias of the table being dropped. The problem is that it must not use the open handler tables list to search because the table might have been closed (marked for reopen) by a flush tables command and also it must not use the current table alias at all since multiple different aliases may be associated with a single table. This is specially visible when a user has two open handlers (using alias) of a same table and a flush tables command is issued before the table is dropped (see test case). Scanning the handler table list is also useless for dropping handlers associated with temporary tables, because temporary tables are not kept in the THD::handler_tables list. The solution is to simple scan the handlers hash table searching for, and deleting all handlers with matching table names if the reopen flag is not passed to the flush function, indicating that the handlers should be deleted. All matching handlers are deleted even if the associated the table is not open. mysql-test/include/handler.inc: Add test case for Bug#31397 mysql-test/r/handler_innodb.result: Add test case result for Bug#31397 mysql-test/r/handler_myisam.result: Add test case result for Bug#31397 sql/mysql_priv.h: Rename flush functions to better match the intent of the caller and update functions prototypes and remove unused flags. sql/sql_base.cc: Rename flush functions to better match the intent of the caller. sql/sql_class.cc: Rename the flush functions to better match the intent of the caller. The hash_free function is moved to the cleanup. sql/sql_handler.cc: When dropping tables for a final close, scan the handler's hash table since the table might not be in the handlers open table list because the table was marked for reopen or because it's a temporary table. sql/sql_rename.cc: Drop handlers associated with tables that are being renamed. sql/sql_table.cc: Now that temporary tables are properly removed even when opened by a SQL HANDLER, enable the assert since this branch can't be taken outside of SF/trigger/prelocked mode. |

Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Bug 26867 - LOCK TABLES + REPAIR + merge table result in
memory/cpu hogging
Bug 26377 - Deadlock with MERGE and FLUSH TABLE
Bug 25038 - Waiting TRUNCATE
Bug 25700 - merge base tables get corrupted by
optimize/analyze/repair table
Bug 30275 - Merge tables: flush tables or unlock tables
causes server to crash
Bug 19627 - temporary merge table locking
Bug 27660 - Falcon: merge table possible
Bug 30273 - merge tables: Can't lock file (errno: 155)
The problems were:
Bug 26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
1. A thread trying to lock a MERGE table performs busy waiting while
REPAIR TABLE or a similar table administration task is ongoing on
one or more of its MyISAM tables.
2. A thread trying to lock a MERGE table performs busy waiting until all
threads that did REPAIR TABLE or similar table administration tasks
on one or more of its MyISAM tables in LOCK TABLES segments do UNLOCK
TABLES. The difference against problem #1 is that the busy waiting
takes place *after* the administration task. It is terminated by
UNLOCK TABLES only.
3. Two FLUSH TABLES within a LOCK TABLES segment can invalidate the
lock. This does *not* require a MERGE table. The first FLUSH TABLES
can be replaced by any statement that requires other threads to
reopen the table. In 5.0 and 5.1 a single FLUSH TABLES can provoke
the problem.
Bug 26867 - LOCK TABLES + REPAIR + merge table result in
memory/cpu hogging
Trying DML on a MERGE table, which has a child locked and
repaired by another thread, made an infinite loop in the server.
Bug 26377 - Deadlock with MERGE and FLUSH TABLE
Locking a MERGE table and its children in parent-child order
and flushing the child deadlocked the server.
Bug 25038 - Waiting TRUNCATE
Truncating a MERGE child, while the MERGE table was in use,
let the truncate fail instead of waiting for the table to
become free.
Bug 25700 - merge base tables get corrupted by
optimize/analyze/repair table
Repairing a child of an open MERGE table corrupted the child.
It was necessary to FLUSH the child first.
Bug 30275 - Merge tables: flush tables or unlock tables
causes server to crash
Flushing and optimizing locked MERGE children crashed the server.
Bug 19627 - temporary merge table locking
Use of a temporary MERGE table with non-temporary children
could corrupt the children.
Temporary tables are never locked. So we do now prohibit
non-temporary chidlren of a temporary MERGE table.
Bug 27660 - Falcon: merge table possible
It was possible to create a MERGE table with non-MyISAM children.
Bug 30273 - merge tables: Can't lock file (errno: 155)
This was a Windows-only bug. Table administration statements
sometimes failed with "Can't lock file (errno: 155)".
These bugs are fixed by a new implementation of MERGE table open.
When opening a MERGE table in open_tables() we do now add the
child tables to the list of tables to be opened by open_tables()
(the "query_list"). The children are not opened in the handler at
this stage.
After opening the parent, open_tables() opens each child from the
now extended query_list. When the last child is opened, we remove
the children from the query_list again and attach the children to
the parent. This behaves similar to the old open. However it does
not open the MyISAM tables directly, but grabs them from the already
open children.
When closing a MERGE table in close_thread_table() we detach the
children only. Closing of the children is done implicitly because
they are in thd->open_tables.
For more detail see the comment at the top of ha_myisammrg.cc.
Changed from open_ltable() to open_and_lock_tables() in all places
that can be relevant for MERGE tables. The latter can handle tables
added to the list on the fly. When open_ltable() was used in a loop
over a list of tables, the list must be temporarily terminated
after every table for open_and_lock_tables().
table_list->required_type is set to FRMTYPE_TABLE to avoid open of
special tables. Handling of derived tables is suppressed.
These details are handled by the new function
open_n_lock_single_table(), which has nearly the same signature as
open_ltable() and can replace it in most cases.
In reopen_tables() some of the tables open by a thread can be
closed and reopened. When a MERGE child is affected, the parent
must be closed and reopened too. Closing of the parent is forced
before the first child is closed. Reopen happens in the order of
thd->open_tables. MERGE parents do not attach their children
automatically at open. This is done after all tables are reopened.
So all children are open when attaching them.
Special lock handling like mysql_lock_abort() or mysql_lock_remove()
needs to be suppressed for MERGE children or forwarded to the parent.
This depends on the situation. In loops over all open tables one
suppresses child lock handling. When a single table is touched,
forwarding is done.
Behavioral changes:
===================
This patch changes the behavior of temporary MERGE tables.
Temporary MERGE must have temporary children.
The old behavior was wrong. A temporary table is not locked. Hence
even non-temporary children were not locked. See
Bug 19627 - temporary merge table locking.
You cannot change the union list of a non-temporary MERGE table
when LOCK TABLES is in effect. The following does *not* work:
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ...;
LOCK TABLES t1 WRITE, t2 WRITE, m1 WRITE;
ALTER TABLE m1 ... UNION=(t1,t2) ...;
However, you can do this with a temporary MERGE table.
You cannot create a MERGE table with CREATE ... SELECT, neither
as a temporary MERGE table, nor as a non-temporary MERGE table.
CREATE TABLE m1 ... ENGINE=MRG_MYISAM ... SELECT ...;
Gives error message: table is not BASE TABLE.

mysql-test/t/myisam.test:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Moved test for bug 8306 from here to merge.test.
mysys/thr_lock.c:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Added code to let the owner of a high priority lock (TL_WRITE_ONLY)
to bypass its own lock.
sql/ha_ndbcluster_binlog.cc:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Added 'thd' argument to init_tmp_table_share().
sql/handler.cc:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Added 'thd' argument to init_tmp_table_share().
sql/mysql_priv.h:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Removed declaration of check_merge_table_access(). It is now static
in sql_parse.cc.
Added declaration for fix_merge_after_open().
Renamed open_and_lock_tables() to open_and_lock_tables_derived()
with additional parameter 'derived'.
Added inline functions simple_open_n_lock_tables() and
open_and_lock_tables(), which call open_and_lock_tables_derived()
and add the argument for 'derived'.

as an replacement for open_ltable() in most situations. Internally
it calls simple_open_n_lock_tables() so hat it is appropriate for
MERGE tables.

Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Defined new functions add_merge_table_list(),

close_handle_and_leave_table_as_lock(), close_thread_tables(),
close_thread_table(), unlink_open_table(), reopen_name_locked_table(),
reopen_table(), drop_locked_tables(), close_temporary_table(),
and open_tables() respectively.
Prevented special lock handling of merge children (like
mysql_lock_remove, mysql_lock_merge or mysql_lock_abort)
at many places. Some of these calls are forwarded to the
parent table instead.

as an replacement for open_ltable() in most situations. Internally
it calls simple_open_n_lock_tables() so hat it is appropriate for
MERGE tables.
Disabled use of open_ltable() for MERGE tables.
Removed function simple_open_n_lock_tables(). It is now inline
declared in mysql_priv.h.

with additional parameter 'derived'. open_and_lock_tables() is now
inline declared in mysql_priv.h.
Added a check for end-of-list in two loops in lock_tables().
