The problem is that passing anything other than a integer to a limit clause in a prepared statement would fail. This limitation was introduced to avoid replication problems (e.g: replicating the statement with a string argument would cause a parse failure in the slave). The solution is to convert arguments to the limit clause to a integer value and use this converted value when persisting the query to the log. mysql-test/r/limit.result: Update test case result. mysql-test/r/ps.result: Add test case result for Bug#33851 mysql-test/r/rpl_user_variables.result: Test case result for replication of prepared statement with limit clause. mysql-test/t/limit.test: Test parameters to limit clause. mysql-test/t/ps.test: Add test case for Bug#33851 mysql-test/t/rpl_user_variables.test: Test replication of a parameter which value is converted. sql/item.cc: Convert value to integer if it's a parameter to a limit clause. sql/item.h: Flag signal that item is a parameter to a limit clause. sql/item_func.cc: Const member functions, object is not mutated. sql/sql_class.h: Const member functions, object is not mutated. sql/sql_yacc.yy: Flag that item is a parameter to a limit clause.

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. 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_load.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_parse.cc: Implement optimisation of read-only transactions: bypass 2-phase commit for them. 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. 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. mysql-test/include/commit.inc: New BitKeeper file ``mysql-test/include/commit.inc'' mysql-test/r/commit_1innodb.result: New BitKeeper file ``mysql-test/r/commit_1innodb.result'' mysql-test/t/commit_1innodb.test: New BitKeeper file ``mysql-test/t/commit_1innodb.test''

subselects into account It is forbidden to use the SELECT INTO construction inside UNION statements unless on the last SELECT of the union. The parser records whether it has seen INTO or not when parsing a UNION statement. But if the INTO was legally used in an outer query, an error is thrown if UNION is seen in a subquery. Fixed in 5.0 by remembering the nesting level of INTO tokens and mitigate the error unless it collides with the UNION. mysql-test/r/union.result: Bug#32858: Test result mysql-test/t/union.test: Bug#32858: Test case sql/sql_class.cc: Bug#32858: Initializing new member sql/sql_class.h: Bug#32858: Added property nest_level to select_result class. sql/sql_yacc.yy: Bug#32858: The fix.

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.

without PK Bug#31609 Not all RBR slave errors reported as errors bug#32468 delete rows event on a table with foreign key constraint fails The first two bugs comprise idempotency issues. First, there was no error code reported under conditions of the bug description although the slave sql thread halted. Second, executions were different with and without presence of prim key in the table. Third, there was no way to instruct the slave whether to ignore an error and skip to the following event or to halt. Fourth, there are handler errors which might happen due to idempotent applying of binlog but those were not listed among the "idempotent" error list. All the named issues are addressed. Wrt to the 3rd, there is the new global system variable, changeble at run time, which controls the slave sql thread behaviour. The new variable allows further extensions to mimic the sql_mode session/global variable. To address the 4th, the new bug#32468 had to be fixed as it was staying in the way. include/my_bitmap.h: basic operations with bits of an integer type are added. mysql-test/extra/rpl_tests/rpl_foreign_key.test: regression test for bug#32468 mysql-test/extra/rpl_tests/rpl_row_basic.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/extra/rpl_tests/rpl_row_tabledefs.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/r/rpl_foreign_key_innodb.result: results changed mysql-test/suite/rpl/r/rpl_idempotency.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_11bugs.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_basic_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_row_mystery22.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_2myisam.result: results changed mysql-test/suite/rpl/r/rpl_row_tabledefs_3innodb.result: results changed mysql-test/suite/rpl/r/rpl_temporary_errors.result: results changed mysql-test/suite/rpl/t/rpl_idempotency.test: extenstions to the test providing testing of complements to the idempotent error set and checking how slave halts when it faces an error from the list when the mode is STRICT. mysql-test/suite/rpl/t/rpl_row_basic_11bugs.test: changes due to bug#31552/31609 idempotency is not default any longer. mysql-test/suite/rpl/t/rpl_row_mystery22.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl/t/rpl_temporary_errors.test: changes due to bug#31552/31609 idempotency is not default any longer mysql-test/suite/rpl_ndb/r/rpl_ndb_dd_advance.result: results changed mysql-test/suite/rpl_ndb/r/rpl_row_basic_7ndb.result: results changed sql/log_event.cc: the fix for bug#32468 delete rows event on a table with foreign key constraint fails ensures the flags are set at proper time so that their values will be caught by innodb. reseting the flags is done along the common error and errorless execution path. The list of idempotent error is extended with foreign keys related items. NDB engine write events are designed with the replace sematics in mind. Therefore the corrsponding ndb handler's flag are (re)set regardless of the slave's execution mode. Rows_log_event::write_row() starts using the bool replace argument as its caller sets it depending on the event's execution mode. sql/log_event.h: adding a new member to hold the slave's mode during execution of the event. sql/mysql_priv.h: changes to link the command line option with the new global sys var. sql/mysqld.cc: introduction of the new command line option. providing its initialization to a default. changes to link the command line option with the new global sys var. sql/rpl_rli.cc: rli post-event-execution cleanup restores the default bits. sql/set_var.cc: The new "standard" sys_var_set class' and the new global system var related declarations and definitions. fix_slave_exec_mode() is used as with the update method of a new class so as at time of the command line arguments parsing. sql/set_var.h: new declarations. The class for the new global sys var is based on yet another new "standard" one. sql/share/errmsg.txt: slave_exec_mode setting error; slave inconsistency error which may be not an error when the intention is "idempotent". I.e consisting of row-based events binlog is being applied for the 2nd (more) time. sql/sql_class.h: The names for the bits of the new sever slave_exec_mode_options. mysql-test/suite/rpl/t/rpl_idempotency-master.opt: innodb is necessary mysql-test/suite/rpl/t/rpl_idempotency-slave.opt: innodb is necessary, as well as the tests start with non-default IDEMPOTENT slave execution mode.

insert ... select. The 5.0 manual page for mysql_insert_id() does not mention anything about INSERT ... SELECT, though its current behavior is incosistent with what the manual says about the plain INSERT. Fixed by changing the AUTO_INCREMENT and mysql_insert_id() handling logic in INSERT ... SELECT to be consistent with the INSERT behavior, the manual, and the changes in 5.1 introduced by WL3146: - mysql_insert_id() now returns the first automatically generated AUTO_INCREMENT value that was successfully inserted by INSERT ... SELECT - if an INSERT ... SELECT statement is executed, and no automatically generated value is successfully inserted, mysql_insert_id() now returns the ID of the last inserted row. sql/sql_class.h: Replaced last_insert_id with autoinc_value_of_last_inserted_row to be consistent with 5.1 code. sql/sql_insert.cc: Revised the AUTO_INCREMENT and mysql_insert_id() handling logic in INSERT ... SELECT to be consistent with INSERT behavior, the manual, and changes in 5.1 introduced by WL3146: - mysql_insert_id() now returns the first automatically generated AUTO_INCREMENT value that was successfully inserted; - if an INSERT ... SELECT statement is executed, and no automatically generated value is successfully inserted, mysql_insert_id() now returns the ID of the last inserted row. tests/mysql_client_test.c: Backported the test cases related to INSERT ... SELECT and mysql_insert_id() from WL3146 patch to 5.0.

led to creating corrupted index. Corrected fix. The new method called prepare2 is added to the select_create class. As all preparations are done by the select_create::prepare function it doesn't do anything. Slightly changed algorithm of calling the start_bulk_insert function. Now it's called from the select_insert::prepare2 function when the SQL_BUFFER_RESULT flags is set. The is_bulk_insert_mode flag is removed as it is not needed anymore. sql/sql_class.h: Bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) .. SELECT led to creating corrupted index.

UNIQUE (eq-ref) lookups result in table being considered as a "constant" table. Queries that consist of only constant tables are processed in do_select() in a special way that doesn't invoke evaluate_join_record(), and therefore doesn't increase the counters join->examined_rows and join->thd->row_count. The patch increases these counters in this special case. NOTICE: This behavior seems to contradict what the documentation says in Sect. 5.11.4: "Queries handled by the query cache are not added to the slow query log, nor are queries that would not benefit from the presence of an index because the table has zero rows or one row." No test case in 5.0 as issue shows only in slow query log, and other counters can give subtly different values (with regard to counting in create_sort_index(), synthetic rows in ROLLUP, etc.). sql/sql_class.h: add documentation for some variables sql/sql_select.cc: Don't forget const tables when counting read records!

Add select_send::cleanup. Fix a compilation warning. Issues spotted while working on the fix for Bug#12713. sql-common/client.c: Fix a warning. sql/sql_class.cc: Give a variable a more specific name. Rewrite an incorrect comment. Add a cleanup for select_send. The only case now this cleanup can be necessary is when we have a prepared statement inside a stored procedure, and a continue handler. At first execution, the statement is killed after having executed select_send::send_fields. At the second execution it is killed after having executed select_send::send_fields. sql/sql_class.h: Rename a member. Add comments.

in the SELECT INTO OUTFILE clause starts with a special character (one of n, t, r, b, 0, Z or N) and ENCLOSED BY is empty, every occurrence of this character within a field value is duplicated. Duplication has been avoided. New warning message has been added: "First character of the FIELDS TERMINATED string is ambiguous; please use non-optional and non-empty FIELDS ENCLOSED BY". mysql-test/r/outfile_loaddata.result: BitKeeper file /home/uchum/work/bk/5.0-opt-31663/mysql-test/r/outfile_loaddata.result Added test case for bug #31663. mysql-test/t/outfile_loaddata.test: BitKeeper file /home/uchum/work/bk/5.0-opt-31663/mysql-test/t/outfile_loaddata.test Added test case for bug #31663. sql/sql_class.h: Fixed bug #31663. The select_export::is_ambiguous_field_term field has been added. This field is true if select_export::field_sep_char contains the first char of the FIELDS TERMINATED BY (ENCLOSED BY is empty), and items can contain this character. The select_export::field_term_char field has been added (first char of the FIELDS TERMINATED BY string or INT_MAX). sql/sql_class.cc: Fixed bug #31663. The select_export::prepare method has been modified to calculate a value of the select_export::is_ambiguous_field_term field and to warn if this value is true. The select_export::send_data method has been modified to avoid escaping or duplication of the field_set_char if is_ambiguous_field_term is true. sql/share/errmsg.txt: Fixed bug #31663. The ER_AMBIGUOUS_FIELD_TERM warning has been added.

similar to bug_27716, but it was stressed on in the synopsis on that there is another side of the artifact affecting behaviour in transaction. Fixed with deploying multi_delete::send_error() - otherwise never called - and refining its logic to perform binlogging job if needed. The changeset includes the following side effects: - added tests to check bug_23333's scenarios on the mixture of tables for multi_update; - fixes bug@30763 with two-liner patch and a test coinciding to one added for bug_23333. mysql-test/r/innodb.result: results changed mysql-test/r/mix_innodb_myisam_binlog.result: results changed mysql-test/r/multi_update.result: results changed mysql-test/t/innodb.test: trans table specific test added mysql-test/t/mix_innodb_myisam_binlog.test: multi-update and multi-delete of mixure of ta and not-ta tables tests added (relates to bug_23333). mysql-test/t/multi_update.test: testing another branch of mult-delete: send_eof() (binloggin there), send_error (early return) sql/sql_class.h: a new flag to designate the fact the statement's error has been handled. The flag is checked by ::send_error() methods (multi_update and _delete classes) sql/sql_delete.cc: expanding multi_delete::send_error to 1. early return if error_handled == t 2. binlogging locally if there was a non-trans table modified side effect sql/sql_parse.cc: adding multi_update::send_error which can perform binlogging and rollback job in needed sql/sql_update.cc: issues relating to 1. bug_27716 with zeroing of `updated' to serve as the flag of early return from send_error(). The flag is changed to be a new member error_handled; also moved outside binlogging branch. The reason for this change is that bug_23333 fixes were pushed after the bug_27716's and they left this flaw (also no test coverage). 2. bug_30763 with assertion on trans_safe. I decide to make 2 liner fix for that bug here instead of to remove those two assertions. This new bug test case is the same as for multi-update on the mixure of tables. The rational for this fix: presumption for mutli_update::trans_safe to be set to zero at multi_update::multi_update or multi_update::initialize_tables() is incorrect. trans_safe := false should happen only when a non-transactional table gets modified. Therefore, at initialization the member must be be set to true.

Problem: one thread could read uninitialized memory from (the stack of) another thread. Fix: swapped order of initializing the memory and making it available to the other thread. Fix: put lock around the statement that makes the memory available to the other thread. Fix: all fields of the struct are now initialized in the constructor, to avoid future problems. sql/sql_class.h: Initialize all members in constructor for more safe future code. sql/sql_repl.cc: Swap order so that linfo is first initialized, then assigned, instead of the other way around. Put a lock around the assignment. We use LOCK_thread_count since log_in_use uses it: log_in_use may be running concurrently, called from MYSQL_LOG::purge_logs.

led to creating corrupted index. While execution of the CREATE .. SELECT SQL_BUFFER_RESULT statement the engine->start_bulk_insert function was called twice. On the first call On the first call MyISAM disabled all non-unique indexes and on the second call it decides to not re-enable them because all indexes was disabled. Due to this no indexes was actually created during CREATE TABLE thus producing crashed table. Now the select_inset class has is_bulk_insert_mode flag which prevents calling the start_bulk_insert function twice. The flag is set in the select_create::prepare, select_insert::prepare2 functions and the select_insert class constructor. The flag is reset in the select_insert::send_eof function. mysql-test/t/insert_select.test: A test case is added for the bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) ..

of statement breaks binlog. There were two problems discovered by this bug: 1. Default (current) database is not fixed at the creation time. That leads to wrong output of DATABASE() function. 2. Database attributes (@@collation_database) are not fixed at the creation time. That leads to wrong resultset. Binlog breakage and Query Cache wrong output happened because of the first problem. The fix is to remember the current database at the PREPARE-time and set it each time at EXECUTE. mysql-test/include/query_cache_sql_prepare.inc: The first part of the test case for BUG#25843. mysql-test/r/query_cache_ps_no_prot.result: Update result file. mysql-test/r/query_cache_ps_ps_prot.result: Update result file. mysql-test/suite/rpl/r/rpl_ps.result: Update result file. mysql-test/suite/rpl/t/rpl_ps.test: The second part of the test case for BUG#25843. sql/mysql_priv.h: Added mysql_opt_change_db() prototype. sql/sp.cc: 1. Polishing; 2. sp_use_new_db() has been removed; 3. Use mysql_opt_change_db() instead of sp_use_new_db(). sql/sp.h: sp_use_new_db() has been removed. This function has nothing to do with a) sp and b) *new* database. It was merely "switch the current database if needed". sql/sp_head.cc: 1. Polishing. 2. Use mysql_opt_change_db() instead of sp_use_new_db(). sql/sql_class.cc: Move THD::{db, db_length} into Statement. sql/sql_class.h: Move THD::{db, db_length} into Statement. sql/sql_db.cc: Introduce mysql_opt_change_db() as a replacement (and inspired by) sp_use_new_db(). sql/sql_prepare.cc: 1. Remember the current database in Prepared_statement::prepare(). 2. Switch/restore the current database in Prepared_statement::execute().

Use mysql_change_db_impl() to reset current database instead of THD::set_db() in mysql_rm_db(). THD::set_db() does not take care of THD::db_access and database attributes (@@collation_database). 2. Polishing: add, fix comments.

Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack Once had been set the flag might later got reset inside of a stored routine execution stack. The reason was in that there was no check if a new statement started at time of resetting. The artifact affects most of binlogable DML queries. Notice, that multi-update is wrapped up within bug@27716 fix, multi-delete bug@29136. Fixed with saving parent's statement flag of whether the statement modified non-transactional table, and unioning (merging) the value with that was gained in mysql_execute_command. Resettling thd->no_trans_update members into thd->transaction.`member`; Asserting code; Effectively the following properties are held. 1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table reflects the fact if such a table got modified by the substatement. That also respects THD::really_abort_on_warnin() requirements. 2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as the union of the values of all invoked sub-statements. That fixes this bug#27417; Computing of thd->transaction.all.modified_non_trans_table is refined to base to the stmt's value for all the case including insert .. select statement which before the patch had an extra issue bug@28960. Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in to temp_table select. The supplied test verifies limitely, mostly asserts. The ultimate testing is defered for bug@13270, bug@23333. mysql-test/r/mix_innodb_myisam_binlog.result: results changed mysql-test/t/mix_innodb_myisam_binlog.test: regression test incl the related bug#28960. sql/ha_ndbcluster.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/handler.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/handler.h: new member added sql/log.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/set_var.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sp_head.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} and saving and merging stmt's flag at the end of a substatement. sql/sql_class.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sql_class.h: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sql_delete.cc: correcting basic delete incl truncate branch and multi-delete queries to set stmt.modified_non_trans_table; optimization to set the flag at the end of per-row loop; multi-delete still has an extra issue similar to bug#27716 of multi-update - to be address with bug_29136 fix. sql/sql_insert.cc: thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sql_load.cc: eliminating a separate issue where the stmt flag was saved and re-stored after write_record that actually could change it and the change would be lost but should remain permanent; thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt} sql/sql_parse.cc: initialization to transaction.stmt.modified_non_trans_table at the common part of all types of statements processing - mysql_execute_command(). sql/sql_table.cc: moving the reset up to the mysql_execute_command() caller sql/sql_update.cc: correcting update query case (multi-update part of the issues covered by other bug#27716 fix) thd->transaction.{all,stmt}.modified_non_trans_table instead of thd->no_trans_update.{all,stmt}

When innodb detects a deadlock it calls ha_rollback_trans() to rollback the main transaction. But such action isn't allowed from inside of triggers and functions. When it happen the 'Explicit or implicit commit' error is thrown even if there is no commit/rollback statements in the trigger/function. This leads to the user confusion. Now the convert_error_code_to_mysql() function doesn't call the ha_rollback_trans() function directly but rather calls the mark_transaction_to_rollback function and returns an error. The sp_rcontext::find_handler() now doesn't allow errors to be caught by the trigger/function error handlers when the thd->is_fatal_sub_stmt_error flag is set. Procedures are still allowed to catch such errors. The sp_rcontext::find_handler function now accepts a THD handle as a parameter. The transaction_rollback_request and the is_fatal_sub_stmt_error flags are added to the THD class. The are initialized by the THD class constructor. Now the ha_autocommit_or_rollback function rolls back main transaction when not in a sub statement and the thd->transaction_rollback_request is set. The THD::restore_sub_statement_state function now resets the thd->is_fatal_sub_stmt_error flag on exit from a sub-statement. sql/ha_innodb.cc: Bug#24989: The DEADLOCK error is improperly handled by InnoDB. Now the convert_error_code_to_mysql() function doesn't call the ha_rollback_trans() function directly but rather calls the mark_transaction_to_rollback function and returns an error. sql/handler.cc: Bug#24989: The DEADLOCK error is improperly handled by InnoDB. Now the ha_autocommit_or_rollback function rolls back main transaction when not in a sub statement and the thd->transaction_rollback_request is set. mysql-test/r/innodb-big.result: Added a test case for the bug#24989: The DEADLOCK error is improperly handled by InnoDB. mysql-test/t/innodb-big.test: Added a test case for the bug#24989: The DEADLOCK error is improperly handled by InnoDB. sql/sql_class.h: Bug#24989: The DEADLOCK error is improperly handled by InnoDB.

Initialization of the transaction_rollback_request and the is_fatal_sub_stmt_error flags are added to the THD class constructor. The mark_transaction_to_rollback function is added.

The sp_rcontext::find_handler function now accepts a THD handle as a parameter. The in_sub_stmt flag is added to the sp_rcontext class. sql/sp_rcontext.cc: Bug#24989: The DEADLOCK error is improperly handled by InnoDB. The sp_rcontext::find_handler() now doesn't allow errors to be caught by the trigger/function error handlers when the thd->is_fatal_sub_stmt_error flag is set. Instead it tries to find a most inner procedure that isn't called directly or indirectly from any function/trigger. Procedures are still allowed to catch such errors. The sp_rcontext::find_handler function now accepts a THD handle as a parameter.

between perm and temp tables. Review fixes. The original bug report complains that if we locked a temporary table with LOCK TABLES statement, we would not leave LOCK TABLES mode when this temporary table is dropped. Additionally, the bug was escalated when it was discovered than when a temporary transactional table that was previously locked with LOCK TABLES statement was dropped, futher actions with this table, such as UNLOCK TABLES, would lead to a crash. The problem originates from incomplete support of transactional temporary tables. When we added calls to handler::store_lock()/handler::external_lock() to operations that work with such tables, we only covered the normal server code flow and did not cover LOCK TABLES mode. In LOCK TABLES mode, ::external_lock(LOCK) would sometimes be called without matching ::external_lock(UNLOCK), e.g. when a transactional temporary table was dropped. Additionally, this table would be left in the list of LOCKed TABLES. The patch aims to address this inadequacy. Now, whenever an instance of 'handler' is destroyed, we assert that it was priorly external_lock(UNLOCK)-ed. All the places that violate this assert were fixed. This patch introduces no changes in behavior -- the discrepancy in behavior will be fixed when we start calling ::store_lock()/::external_lock() for all tables, regardless whether they are transactional or not, temporary or not. mysql-test/r/innodb_mysql.result: Update test results (Bug#24918) mysql-test/t/innodb_mysql.test: Add a test case for Bug#24918 sql/handler.h: Make handler::external_lock() a protected method. Backport from 5.1 its public wrapper handler::ha_external_lock(). Assert that the handler is not closed if it is still locked. sql/lock.cc: In mysql_lock_tables only call lock_external() for the list of tables that we called store_lock() for. E.g. get_lock_data() does not add non-transactional temporary tables to the lock list, so lock_external() should not be called for them. Use handler::ha_external_lock() instead of handler::external_lock(). Add comments for mysql_lock_remove(), parameterize one strange side effect that it has. At least in one place where mysql_lock_remove is used, this side effect is not desired (DROP TABLE). The parameter will be dropped in 5.1, along with the side effect. sql/mysql_priv.h: Update declaration of mysql_lock_remove(). sql/opt_range.cc: Deploy handler::ha_external_lock() instead of handler::external_lock() sql/sql_base.cc: When closing a temporary table, remove the table from the list of LOCKed TABLES of this thread, in case it's there. It's there if it is a transactional temporary table. Use a new declaration of mysql_lock_remove(). sql/sql_class.h: Extend the comment for THD::temporary_tables. sql/sql_table.cc: Deploy handler::ha_external_lock() instead of handler::external_lock()

Bug#25422 (Hang with log tables) Bug 17876 (Truncating mysql.slow_log in a SP after using cursor locks the thread) Bug 23044 (Warnings on flush of a log table) Bug 29129 (Resetting general_log while the GLOBAL READ LOCK is set causes a deadlock) Prior to this fix, the server would hang when performing concurrent ALTER TABLE or TRUNCATE TABLE statements against the LOG TABLES, which are mysql.general_log and mysql.slow_log. The root cause traces to the following code: in sql_base.cc, open_table() if (table->in_use != thd) { /* wait_for_condition will unlock LOCK_open for us */ wait_for_condition(thd, &LOCK_open, &COND_refresh); } The problem with this code is that the current implementation of the LOGGER creates 'fake' THD objects, like - Log_to_csv_event_handler::general_log_thd - Log_to_csv_event_handler::slow_log_thd which are not associated to a real thread running in the server, so that waiting for these non-existing threads to release table locks cause the dead lock. In general, the design of Log_to_csv_event_handler does not fit into the general architecture of the server, so that the concept of general_log_thd and slow_log_thd has to be abandoned: - this implementation does not work with table locking - it will not work with commands like SHOW PROCESSLIST - having the log tables always opened does not integrate well with DDL operations / FLUSH TABLES / SET GLOBAL READ_ONLY With this patch, the fundamental design of the LOGGER has been changed to: - always open and close a log table when writing a log - remove totally the usage of fake THD objects - clarify how locking of log tables is implemented in general. See WL#3984 for details related to the new locking design. Additional changes (misc bugs exposed and fixed): 1) mysqldump which would ignore some tables in dump_all_tables_in_db(), but forget to ignore the same in dump_all_views_in_db(). 2) mysqldump would also issue an empty "LOCK TABLE" command when all the tables to lock are to be ignored (numrows == 0), instead of not issuing the query. 3) Internal errors handlers could intercept errors but not warnings (see sql_error.cc). 4) Implementing a nested call to open tables, for the performance schema tables, exposed an existing bug in remove_table_from_cache(), which would perform: in_use->some_tables_deleted=1; against another thread, without any consideration about thread locking. This call inside remove_table_from_cache() was not required anyway, since calling mysql_lock_abort() takes care of aborting -- cleanly -- threads that might hold a lock on a table. This line (in_use->some_tables_deleted=1) has been removed. sql/handler.cc: Moved logic for system / log tables in the SQL layer. sql/handler.h: Moved logic for system / log tables in the SQL layer. sql/lock.cc: Revised locking of log tables sql/log.cc: Major cleanup: changed how log tables are locked / written to. sql/log.h: Major cleanup: changed how log tables are locked / written to. sql/mysql_priv.h: performance schema helpers sql/slave.cc: open_ltable() lock flags sql/sp.cc: open_ltable() lock flags sql/sql_acl.cc: open_ltable() lock flags sql/sql_class.h: performance schema helpers sql/sql_delete.cc: log tables cleanup in TRUNCATE sql/sql_error.cc: Internal handlers can also intercept warnings sql/sql_insert.cc: open_ltable() lock flags sql/sql_parse.cc: performance schema helpers sql/sql_plugin.cc: open_ltable() lock flags sql/sql_rename.cc: log tables cleanup in RENAME sql/sql_servers.cc: open_ltable() lock flags sql/sql_show.cc: Move INFORMATION_SCHEMA_NAME to table.cc sql/sql_table.cc: log tables cleanup (admin operations, ALTER TABLE) sql/sql_udf.cc: open_ltable() lock flags sql/table.cc: Implemented TABLE_CATEGORY. sql/share/errmsg.txt: Changed the wording and name of ER_CANT_READ_LOCK_LOG_TABLE sql/table.h: Implemented TABLE_CATEGORY. storage/csv/ha_tina.cc: Moved logic for system / log tables in the SQL layer. storage/csv/ha_tina.h: Moved logic for system / log tables in the SQL layer. storage/myisam/ha_myisam.cc: Moved logic for system / log tables in the SQL layer. storage/myisam/ha_myisam.h: Moved logic for system / log tables in the SQL layer. client/mysqldump.c: Don't lock tables in the ignore list.

we now have exclusive name lock on the table name in mysql_rm_table_part2, we still should keep LOCK_open - some storage engines are not ready for locking scope change and assume that LOCK_open is kept. Still, the binary logging and query cache invalidation calls moved out of LOCK_open scope. Fixes some of the broken 5.1-runtime tests (tests break on asserts). sql/ha_ndbcluster.cc: Do not lock LOCK_open for mysql_rm_table_part2 - it does that for us now. sql/mysql_priv.h: Remove an unused flag. sql/sql_class.h: Fix an unrelated compiler warning. sql/sql_db.cc: Adjust to the changed signature. sql/sql_table.cc: mysql_rm_table_part2: we need to keep LOCK_open while calling storage engine functions, even though now we have an exclusive lock on the table name. Some of them assume that it's kept and attempt to unlock it.

gettimeofday() can fail and presumably, so can time(). Keep an eye on it. Since we have no data on this at all so far, we just retry on failure (and log the event), assuming that this is just an intermittant failure. This might of course hang the threat until we succeed. Once we know more about these failures, an appropriate more clever scheme may be picked (only try so many times per thread, etc., if that fails, return last "good" time() we got or some such). Using sql_print_information() to log as this probably only occurs in high load scenarios where the debug- trace likely is disabled (or might interfere with testing the effect). No test-case as this is a non-deterministic issue. sql/mysql_priv.h: Bug#27198: Error returns from time() are ignored move declarations for log.cc to before inclusion of sql_class.h as we now use sql_print_information() in there. sql/sql_class.h: Bug#27198: Error returns from time() are ignored gettimeofday() can fail and presumably, so can time(). Keep an eye on it.
