BUG#36197: flush tables (or little table cache) can cause crash on slave
When flushing tables, there were a slight chance that the flush was occuring between processing of two table map events. Since the tables are opened one by one, it might result in that the tables were not valid and that sub- sequent locking of tables would cause the slave to crash. The problem is solved by opening and locking all tables at once using simple_open_n_lock_tables(). Also, the patch contain a change to open_tables() so that pre-locking only takes place when the trg_event_map is not zero, which was not the case before (this caused the lock to be placed in thd->locked_tables instead of thd->lock since the assumption was that triggers would be called later and therefore the tables should be pre-locked). mysql-test/suite/rpl/r/rpl_found_rows.result: Result change mysql-test/suite/rpl/r/rpl_row_inexist_tbl.result: Result change mysql-test/suite/rpl/t/rpl_found_rows.test: Adding drop of table that was created in test. mysql-test/suite/rpl/t/rpl_slave_status.test: Adding waits for slave start and stop to ensure that test works. sql/log_event.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/log_event_old.cc: Replacing table-by-table open and lock with a single call to simple_open_n_lock_tables(), which in turn required some changes to other code. sql/sql_base.cc: Extending check inside open_tables() so that pre-locking in only done if tables->trg_egent_map is non-zero. mysql-test/include/wait_for_slave_sql_to_start.inc: New BitKeeper file ``mysql-test/include/wait_for_slave_sql_to_start.inc'' |

Tentative implementation of
WL#4165 Prepared statements: validation WL#4166 Prepared statements: automatic re-prepare Fixes Bug#27430 Crash in subquery code when in PS and table DDL changed after PREPARE Bug#27690 Re-execution of prepared statement after table was replaced with a view crashes Bug#27420 A combination of PS and view operations cause error + assertion on shutdown The basic idea of the patch is to keep track of table metadata between prepared statement prepare and execute. If some table used in the statement has changed, the prepared statement is re-prepared before execution. See WL#4165 and WL#4166 contents and comments in the code for details of the implementation. include/my_global.h: Remove 'register' keyword to avoid warnings when swapping large structures that don't fit into a register. Any modern compiler is capable of placing a variable in a register when that would benefit performance. mysql-test/r/ps_1general.result: Update test results: since now we re-prepare automatically, more correct results are produced in prepare-ddl-execute scenario. mysql-test/r/query_cache_merge.result: Ensure that the table definition cache is large enough for the test to pass in --ps-protocol mysql-test/r/trigger.result: Update test results to reflect automatic statement reprepare. mysql-test/t/disabled.def: Enable ps_ddl.test, which now passes. mysql-test/t/ps_1general.test: Since now we re-execute prepared statements after DDL successfully, change the test to produce repeatable results. Remove expectancy of an error in one place where now we automatically reprepare the prepared statement. mysql-test/t/query_cache_merge.test: Ensure the table definition cache is large enough for the test to pass in --ps-protocol mysql-test/t/trigger.test: Sinc sql/item.cc: Implement Item_param "copy" functionality, used at re-prepare of a prepared statement. We copy the type of the original parameter, and move the assigned value, if any. Sic, the value is "moved", since it can be quite big -- e.g. in case we deal with a LONG DATA parameter. It's essential to move the value from the old parameter since at the time of re-prepare the client packet with the necessary information may be not available. sql/item.h: Declare a new method used for reprepare. sql/my_decimal.h: Implement "swap()" functionality of class my_decimal to be able to easily swap two decimal values. sql/mysql_priv.h: Declare enum_metadata_type. sql/mysqld.cc: Implement a status variable for the number of reprepared statements. sql/sql_base.cc: Implement metadata version validation. sql/share/errmsg.txt: Add two new error messages: ER_NEED_REPREPARE and ER_PS_REBIND. The first error (theoretically) never reaches the user. It is issued by the metadata validation framework when a metadata version has changed between prepare and execute. Later on it's intercepted and the statement is automatically re-prepared. Only if the error has occurred repeatedly MAX_REPREPARE_ATTEMTS (3) times do we return it to the user. The second error is issued when after re-prepare we discover that the metadata we sent over to the client using the binary protocol differs drammatically from the new result set metadata that the reprepared statement produces (e.g. number of result set columns is different). sql/sql_class.cc: Implement metadata version validation framework. sql/sql_class.h: Declarations for metadata version validation framework. sql/sql_parse.cc: Mark commands for which we must invalidate and reprepare a prepared statement when metadata has changed. sql/sql_prepare.cc: Implement WL#4165 and WL#4166 (limited support of metadata validation and re-prepare). sql/table.h: Implement metadata validation. tests/mysql_client_test.c: Add a test case for WL#4166 |

Bug #26461: Intrinsic data type bool (1 byte) redefined to BOOL (4 bytes)
The bool data type was redefined to BOOL (4 bytes on windows). Removed the #define and fixed some of the warnings that were uncovered by this. Note that the fix also disables 2 warnings : 4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning) 4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation These warnings will be handled in a separate bug, as they are performance related or bogus. Fixed to int the return type of functions that return more than 2 distinct values.

A fix and a test case for Bug#12713 "Error in a stored function called from
a SELECT doesn't cause ROLLBACK of statem". The idea of the fix is to ensure that we always commit the current statement at the end of dispatch_command(). In order to not issue redundant disc syncs, an optimization of the two-phase commit protocol is implemented to bypass the two phase commit if the transaction is read-only. mysql-test/suite/binlog/r/binlog_row_mix_innodb_myisam.result: Update test results. mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result: Update test results. mysql-test/suite/rpl_ndb/t/disabled.def: Disable the tests, for which this changeset reveals a bug: the injector thread does not always add 'statement commit' to the rows injected in circular replication set up. To be investigated separately. sql/ha_ndbcluster_binlog.cc: Add close_thread_tables() to run_query: this ensures that all tables are closed and there is no pending statement transaction. sql/handler.cc: Implement optimisation of read-only transactions. If a transaction consists only of DML statements that do not change data, we do not perform a two-phase commit for it (run one phase commit only). sql/handler.h: Implement optimisation of read-only transactions. If a transaction consists only of DML statements that do not change data, we do not perform a two-phase commit for it (run one phase commit only). sql/log.cc: Mark the binlog transaction read-write whenever it's started. We never read from binlog, so it's safe and least intrusive to add this mark up here. sql/log_event.cc: Update to the new layout of thd->transaction. sql/rpl_injector.cc: Always commit statement transaction before committing the global one. sql/sp.cc: Ad comments. sql/sp_head.cc: Add comments. sql/sql_base.cc: Commit transaction at the end of the statement. Always. sql/sql_class.cc: Update thd_ha_data to return the right pointer in the new layout. Fix select_dumpvar::send_data to properly return operation status. A test case from commit.inc would lead to an assertion failure in the diagnostics area (double assignment). Not test otherwise by the test suite. sql/sql_class.h: Implement a new layout of storage engine transaction info in which it is easy to access all members related to the handlerton only based on ht->slot. sql/sql_cursor.cc: Update to the new layout of thd->transaction. sql/sql_delete.cc: Remove wrong and now redundant calls to ha_autocommit_or_rollback. The transaction is committed in one place, at the end of the statement. Remove calls to mysql_unlock_tables, since some engines count locks and commit statement transaction in unlock_tables(), which essentially equates mysql_unlock_tables to ha_autocommit_or_rollback. Previously it was necessary to unlock tables soon because we wanted to avoid sending of 'ok' packet to the client under locked tables. This is no longer necessary, since OK packet is also sent from one place at the end of transaction. sql/sql_do.cc: Add DO always clears the error, we must rollback the current statement before this happens. Otherwise the statement will be committed, and not rolled back in the end. sql/sql_insert.cc: Remove wrong and now redundant calls to ha_autocommit_or_rollback. The transaction is committed in one place, at the end of the statement. Remove calls to mysql_unlock_tables, since some engines count locks and commit statement transaction in unlock_tables(), which essentially equates mysql_unlock_tables to ha_autocommit_or_rollback.

Always commit statement transaction before commiting the global one. Fix an unrelated crash in check_table_access, when called from information_schema. sql/sql_partition.cc: Partitions commit at the end of a DDL operation. Make sure that send_ok() is done only if the commit has succeeded. sql/sql_table.cc: Use ha_autocommit_or_rollback and end_active_trans everywhere. Add end_trans to mysql_admin_table, so that it leaves no pending transaction. sql/sql_udf.cc: Remvove a redundant call to close_thread_tables() sql/sql_update.cc: Remove wrong and now redundant calls to ha_autocommit_or_rollback.

A fix and a test case for Bug#34166 Server crash in SHOW OPEN TABLES and
pre-locking. The crash was caused by an implicit assumption in check_table_access() that table_list parameter is always a part of lex->query_tables. When iterating over the passed list of tables, check_table_access() used to stop only when lex->query_tables_last_not_own was reached. In case of pre-locking, lex->query_tables_last_own is not NULL and points to some element of lex->query_tables. When the parameter of check_table_access() was not part of lex->query_tables, loop invariant could never be violated and a crash would happen when the current table pointer would point beyond the end of the provided list. The fix is to change the signature of check_table_access() to also accept a numeric limit of loop iterations, similarly to check_grant(), and supply this limit in all places when we want to check access of tables that are outside lex->query_tables, or just want to check access to one table. mysql-test/r/information_schema.result: Update test results (Bug#34166). mysql-test/t/information_schema.test: Add a test case for Bug#34166. sql/mysql_priv.h: Change signature of check_table_access() to accept a numeric limit of tables to check. sql/sp_head.cc: Update to the new signature of check_table_access(). sql/sql_acl.cc: Improve code clarity: if there is a numeric limit, we should not need to look at first_not_own_table. sql/sql_base.cc: Update to the new signature of check_table_access(). sql/sql_cache.cc: Update to the new signature of check_table_access(). sql/sql_parse.cc: Update to the new signature of check_table_access(). Change check_table_access() to accept an optional numeric limit of tables to check. A crash would happen when check_table_access() was passed a list of tables that is not part of lex->query_tables and lex->query_tables_last_own was not NULL. sql/sql_plugin.cc: Update to the new signature of check_table_access(). sql/sql_prepare.cc: Update to the new signature of check_table_access(). sql/sql_show.cc: Update to the new signature of check_table_access(). Ensure that check_table_access() only checks access to the first table in the table list when called from list_open_tables(). list_open_tables() supplies a table list that is created on stack, whereas check_table_access() used to assume that the supplied list is a part of thd->lex. sql/sql_trigger.cc: Update to the new signature of check_table_access(). sql/sql_view.cc: Update to the new signature of check_table_access(). |

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

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:
Deploy class Diagnostics_area.
Remove the unnecessary juggling with the protocol in
Select_fetch_protocol_binary::send_eof(). EOF packet format is
protocol-independent.
sql/sql_select.cc:
Call fatal_error() directly in opt_sum_query.
Call my_error() whenever we call thd->fatal_error().
sql/sql_servers.cc:
Use getters to access error information in THD.
sql/sql_show.cc:
Use getters to access error information in THD.
Add comments.
Call my_error() whenever we call fatal_error().
sql/sql_table.cc:
Replace hacks with no_send_ok with the interface of the diagnostics area.
Clear the error if ENOENT error in ha_delete_table().
sql/sql_update.cc:
Introduce multi_update::abort(), which is the proper way to abort a
multi-update. This fixes the merge conflict between this patch and
the patch for Bug 29136.
sql/table.cc:
Use a getter to access error information in THD.
sql/tztime.cc:
Use a getter to access error information in THD.

Bug#30273 - merge tables: Can't lock file (errno: 155)
The patch for Bug 26379 (Combination of FLUSH TABLE and REPAIR TABLE corrupts a MERGE table) fixed this bug too. However it revealed a new bug that crashed the server. Flushing a merge table at the moment when it is between open and attach of children crashed the server. The flushing thread wants to abort locks on the flushed table. It calls ha_myisammrg::lock_count() and ha_myisammrg::store_lock() on the TABLE object of the other thread. Changed ha_myisammrg::lock_count() and ha_myisammrg::store_lock() to accept non-attached children. ha_myisammrg::lock_count() returns the number of MyISAM tables in the MERGE table so that the memory allocation done by get_lock_data() is done correctly, even if the children become attached before ha_myisammrg::store_lock() is called. ha_myisammrg::store_lock() will not return any lock if the children are not attached. This is however a change in the handler interface. lock_count() can now return a higher number than store_lock() stores locks. This is more safe than the reverse implementation would be. get_lock_data() in the SQL layer is adjusted accordingly. It sets MYSQL_LOCK::lock_count based on the number of locks returned by the handler::store_lock() calls, not based on the numbers returned by the handler::lock_count() calls. The latter are only used for allocation of memory now. No test case. The test suite cannot reliably run FLUSH between lock_count() and store_lock() of another thread. The bug report contains a program that can repeat the problem with some probability. include/myisammrg.h: Bug#30273 - merge tables: Can't lock file (errno: 155) Added mutex to struct st_myrg_info (MYRG_INFO). sql/handler.h: Bug#30273 - merge tables: Can't lock file (errno: 155) Extended comments for handler::lock_count() and handler::store_lock(). sql/lock.cc: Bug#30273 - merge tables: Can't lock file (errno: 155) Changed get_lock_data() so that the final lock_count is taken from the number of locks returned from handler::store_lock() instead of from handler::lock_count(). sql/sql_base.cc: Fixed a purecov comment.

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#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 #31153 calling stored procedure crashes server if available memory is low
When the server was out of memory it crashed because of invalid memory access. This patch adds detection for failed memory allocations and make the server output a proper error message. sql/mysqld.cc: Don't try to push_warning from within push_warning. It will cause a recursion until the stack is consumed. If my_net_init fails (for example: because of OOM) the temporary vio object might have been attached to the thd object already. This will cause a double free on the vio object when the thd object is deleted later on and the server will crash. sql/sp_head.cc: Added check for out-of-memory on a 'new' operation. Refactored reset_lex method to return a error state code instead of void. Initialize the mem-root with init_sql_alloc to get a basic error handler for memory allocation problems. This alone won't prevent the server from crashing, NULL pointers have to be accounted for as well. sql/sp_head.h: Use the throw() clause in operator new, to indicate to the compiler that memory allocation can fail and return NULL, so that the compiler should generate code to check for NULL before invoking C++ constructors, to be crash safe. sql/sql_base.cc: Use init_sql_alloc to get basic out-of-memory error handling. sql/sql_lex.h: Use the throw() clause in operator new, to indicate to the compiler that memory allocation can fail and return NULL, so that the compiler should generate code to check for NULL before invoking C++ constructors, to be crash safe. sql/sql_prepare.cc: Use init_sql_alloc to get basic out-of-memory error handling. sql/sql_yacc.yy: Check for memory allocation failures where it matters. |

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.

Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Added a check to avoid closing of MyISAM tables when the
child tables are not attached.
Added freeing of rec_per_key_part when the child tables
are not attached.
storage/myisammrg/myrg_extra.c:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE

Some ::extra() functions and ::reset() can be called when
children are detached.
storage/myisammrg/myrg_open.c:
Bug#26379 - Combination of FLUSH TABLE and REPAIR TABLE
corrupts a MERGE table
Kept old myrg_open() for MERGE use independent from MySQL.
Removed an always true condition in myrg_open().
Set children_attached for independent MERGE use in myrg_open().
Added myrg_parent_open(), myrg_attach_children(), and
myrg_detach_children() for the new MERGE table open approach.

Bug #31562: HAVING and lower case
The columns in HAVING can reference the GROUP BY and SELECT columns. There can be "table" prefixes when referencing these columns. And these "table" prefixes in HAVING use the table alias if available. This means that table aliases are subject to the same storage rules as table names and are dependent on lower_case_table_names in the same way as the table names are. Fixed by : 1. Treating table aliases as table names and make them lowercase when printing out the SQL statement for view persistence. 2. Using case insensitive comparison for table aliases when requested by lower_case_table_names mysql-test/r/lowercase_view.result: Bug #31562: test case mysql-test/t/lowercase_view.test: Bug #31562: test case sql/item.cc: Bug #31562: lower_case_table_name contious comparison when searching in GROUP BY sql/sql_base.cc: Bug #31562: lower_case_table_name contious comparison when searching in SELECT sql/sql_select.cc: Bug #31562: treat table aliases as table names and make them lowercase when printing |
