2630.39.1, 2630.28.29, 2630.34.3, 2630.34.2, 2630.34.1, 2630.29.29, 2630.29.28, 2630.31.1, 2630.28.13, 2630.28.10, 2617.23.14 and some other minor revisions. This patch implements: WL#4264 "Backup: Stabilize Service Interface" -- all the server prerequisites except si_objects.{h,cc} themselves (they can be just copied over, when needed). WL#4435: Support OUT-parameters in prepared statements. (and all issues in the initial patches for these two tasks, that were discovered in pushbuild and during testing). Bug#39519: mysql_stmt_close() should flush all data associated with the statement. After execution of a prepared statement, send OUT parameters of the invoked stored procedure, if any, to the client. When using the binary protocol, send the parameters in an additional result set over the wire. When using the text protocol, assign out parameters to the user variables from the CALL(@var1, @var2, ...) specification. The following refactoring has been made: - Protocol::send_fields() was renamed to Protocol::send_result_set_metadata(); - A new Protocol::send_result_set_row() was introduced to incapsulate common functionality for sending row data. - Signature of Protocol::prepare_for_send() was changed: this operation does not need a list of items, the number of items is fully sufficient. The following backward incompatible changes have been made: - CLIENT_MULTI_RESULTS is now enabled by default in the client; - CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client. include/mysql.h: Add a new flag to MYSQL_METHODS::flush_use_result function pointer. This flag determines if all results should be flushed or only the first one: - if flush_all_results is TRUE, then cli_flush_use_result() will read/flush all pending results. I.e. it will read all packets while server status attribute indicates that there are more results. This is a new semantic, required to fix the bug. - if flush_all_results is FALSE, the old sematic is preserved -- i.e. cli_flush_use_result() reads data until first EOF-packet. include/mysql.h.pp: Update the ABI with new calls (compatible changes). include/mysql_com.h: Add CLIENT_PS_OUT_PARAMS -- a client capability indicating that the client supportsю libmysql/libmysql.c: Add mysql_stmt_next_result() -- analogue of mysql_next_result() for binary protocol. Fix a minor bug in alloc_fields() -- not all members were copied over, and some only shallow-copied (catalog). Flush all results in mysql_stmt_close() (Bug#39519). libmysqld/lib_sql.cc: Rename send_fields() -> send_result_set_metadata(). Refactoring: change prepare_for_send() so that it accepts only what it really needs -- a number of elements in the list. mysql-test/r/ps.result: Update results: WL#4435. mysql-test/t/ps.test: WL#4435: A test case for an SQL-part of the problem. sql-common/client.c: Bug#39519. Implement new functionality in cli_flush_use_result(): if flush_all_delete is TRUE, then it should read/flush all pending results. sql/Makefile.am: Add a new header sql_prepare.h to the list of build headers. sql/events.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/handler.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/mysql_priv.h: Move sql_prepare.cc-specific declarations to a new header - sql_prepare.h. sql/procedure.h: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/protocol.cc: Move the logic responsible for sending of one result set row to the Protocol class. Define a template for end-of-statement action. Refactoring: change prepare_for_send() so that it accepts only what it really needs -- a number of elements in the list. Rename send_fields() to send_result_set_metadata(). sql/protocol.h: Update with new declarations (WL#4435). Rename send_fields() -> send_result_set_metadata(). prepare_for_send() only needs the number of columns to send, and doesn't use the item list - update signature to require only what's needed. Add a new protocol type -- Protocol_local. sql/repl_failsafe.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/slave.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_acl.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_base.cc: Include sql_prepare.h (for Reprepare_observer). sql/sql_cache.cc: Extend the query cache flags block to be able to store a numeric id for the result format, not just a flag binary/non-binary. sql/sql_class.cc: Update to use the rename of Protocol::send_fields() to Protocol::send_result_set_metadata(). Use Protocol::send_one_result_set_row(). sql/sql_class.h: Move the declaration of Reprepare_observer to the new header - sql_prepare.h. Update to the new signature of class Protocol::send_fields(). sql/sql_connect.cc: Use a protocol template method instead of raw NET layer API at the end of a statement. sql/sql_cursor.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_error.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_handler.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). Use new method Protocol::send_one_result_set_row(). sql/sql_help.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_lex.cc: Initialize multi_statements variable. Add a handy constant for empty lex string. sql/sql_lex.h: Add a separate member for a standalone parsing option - multi-statements support. sql/sql_list.cc: sql_list.h is a standalone header now, no need to include mysql_priv.h. sql/sql_list.h: Make sql_list.h a stand-alone header. sql/sql_parse.cc: Include sql_prepare.h for prepared statements- related declarations. Use a new Protocol template method to end each statement (send OK, EOF or ERROR to the client). sql/sql_prepare.cc: Implement Execute Direct API (WL#4264), currently unused. It will be used by the service interface (Backup). Use a new header - sql_prepare.h. Add support for OUT parameters in the binary and text protocol (prepared statements only). sql/sql_prepare.h: Add a new header to contain (for now) all prepared statement- external related declarations. sql/sql_profile.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_repl.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_select.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_show.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_string.h: Add a way to convert a String to LEX_STRING. sql/sql_table.cc: Rename: Protocol::send_fields() -> Protocol::send_result_set_metadata(). sql/sql_update.cc: Remove an extraneous my_error(). The error is already reported in update_non_unique_table_error(). sql/sql_yacc.yy: Support for multi-statements is an independent property of parsing, not derived from the protocol type. tests/mysql_client_test.c: Add tests for WL#4435 (binary protocol).

The problem was that JOIN::cleanup() works only if JOIN::table is not null, but JOIN::cleanup also assigns JOIN::table to NULL. This assignment is apparently there for safety, from the times when we had no support for correlated subqueries. Indeed, in case of a evaluation of a correlated subquery more than once it led to JOIN::cleanup doing nothing, and leaving the rnd or index read open. In do_select(), make sure we call JOIN::join_free() even in case of an error. sql/sql_select.h: Remove JOIN::table, JOIN::all_tables has the same functionality.

A fix and a test case for Bug#34898 "mysql_info() reports 0 warnings while mysql_warning_count() reports 1" Review the patch by Chad Miller, implement review comments (since Chad left) and push the patch. This bug is actually not a bug. At least according to Monty. See Bug#841 "wrong number of warnings" reported back in July 2003 and closed as "not a bug". mysql_info() was printing the number of truncated columns, not the number of warnings. But since the message of mysql_info() was "Warnings: <number of truncated columns>", people would expect to get the number of warnings in it, not the number of truncated columns. So a possible fix would be to change the message of mysql_info() to say Rows changed: <n>, truncated: <m>. Instead, put the number of warnings there. That is, remove the feature that thd->cuted_fields (the number of truncated fields) is exposed to the client. The number of truncated columns can be calculated on the client, by analyzing SHOW WARNINGS output, and in future we may remove thd->cuted_fields altogether. So let's have one less thing to worry about. client/mysqltest.cc: Fix a bug in mysqltest program which used to return a wrong number of affected rows in ps-protocol, and a wrong mysql_info() information in both protocols in presence of warnings. mysql-test/r/insert.result: Update results (Bug#34898) mysql-test/suite/rpl/r/rpl_udf.result: Update to the changed output of mysqltest: mysql_info() is now printed before warnings. mysql-test/t/insert.test: Add a test case for Bug#34898. sql/sql_table.cc: A fix for Bug#34898 - report statement warn count, not the number of truncated values in mysql_info(). sql/sql_update.cc: A fix for Bug#34898 - report statement warn count, not the number of truncated values in mysql_info().

redefining trigger The 'table->auto_increment_field_not_null' flag is only valid within processing of a single row, and should be set to FALSE before navigating to the next row, or exiting the operation. This bug was caused by an SQL error occuring while executing a trigger after the flag had been set, so the normal resetting was bypassed. The table object was then returned to the table share's cache in a dirty condition. When the table object was reused, an assert caught that the flag was set. This patch explicitly clears the flag on error/abort. Backported from mysql-6.0-codebase revid: 2617.52.1

get_table_share, drop_open_table In the partition handler code, LOCK_open and share->LOCK_ha_data are acquired in the wrong order in certain cases. When doing a multi-row INSERT (i.e a INSERT..SELECT) in a table with auto- increment column(s). the increments must be in a monotonically continuous increasing sequence (i.e it can't have "holes"). To achieve this, a lock is held for the duration of the operation. share->LOCK_ha_data was used for this purpose. Whenever there was a need to open a view _during_ the operation (views are not currently pre-opened the way tables are), and LOCK_open was grabbed, a deadlock could occur. share->LOCK_ha_data is other places used _while_ holding LOCK_open. A new mutex was introduced in the HA_DATA_PARTITION structure, for exclusive use of the autoincrement data fields, so we don't need to overload the use of LOCK_ha_data here. A module test case has not been supplied, since the problem occurs as a result of a race condition, and testing for this condition is thus not deterministic. Testing for it could be done by setting up a test case as described in the bug report.

When assigning the new string value to the variable, the Item::str_value member was used. This is not according to the protocol. str_value is an internal member used for temporary assignments, and is not consistently set for all string operations. It is set for constant strings, so it would work in these cases, but not for string functions (concat, substr, etc.) The correct approach is to use Item::val_str(..) to evaluate and retrieve the string.

Bug #47274 assert in open_table on CREATE TABLE <already existing> The problem was an assertion during execution of CREATE TABLES. This assertion would occur if INSERT DELAYED or REPLACE DELAYED were used to update a table containing an AUTO_INCREMENT column and if the inserted row had a user-supplied value for that column. Any CREATE TABLE statement (including CREATE TABLE SELECT and CREATE TABLE LIKE) trying to create the same table and which followed the INSERT/REPLACED would cause the assertion. The problem was only noticeable on debug builds of the server and not present in the mysql-5.1 tree. The cause of the problem was that the code for delayed insert did not properly reset the TABLE->auto_increment_if_null flag after The flag is used to indicate that a non-null value of an auto_increment field has been provided by the user or retrieved from a current record. Open_tables() contains an assertion that tests this flag, and this was triggered by CREATE TABLE. This patch fixes the problem by resetting the auto_increment_if_null field to FALSE once INSERT/REPLACE DELAYED has updated the table, similar to what is done already for regular INSERT statements. Test case added to delayed.test.

not on predefined values The default name of the PID file was constructed, as documented, based on the hostname. This name was subsequently used as the base for the general log file name. If the name of the PID file was overridden in the configuration, and no explicit name was set for the general log file, the path location for the PID file was used also for the general log file. A new variable, 'default_logfile_name', has been introduced. This name is constructed based on the hostname, and is then used to construct both the PID file and the general log file. The general log file will now, unless explicitly set, be located in the server data directory (as documentated in the server docs) mysql-test/t/log_state.test: run/mysqld.log was created as a consequence of this bug. After the fix it is no longer created, and will thus not be deleted.
