WL#3146 "less locking in auto_increment": this is a cleanup patch for our current auto_increment handling: new names for auto_increment variables in THD, new methods to manipulate them (see sql_class.h), some move into handler::, causing less backup/restore work when executing substatements. This makes the logic hopefully clearer, less work is is needed in mysql_insert(). By cleaning up, using different variables for different purposes (instead of one for 3 things...), we fix those bugs, which someone may want to fix in 5.0 too: BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate statement-based" BUG#20341 "stored function inserting into one auto_increment puts bad data in slave" BUG#19243 "wrong LAST_INSERT_ID() after ON DUPLICATE KEY UPDATE" (now if a row is updated, LAST_INSERT_ID() will return its id) and re-fixes: BUG#6880 "LAST_INSERT_ID() value changes during multi-row INSERT" (already fixed differently by Ramil in 4.1) Test of documented behaviour of mysql_insert_id() (there was no test). The behaviour changes introduced are: - LAST_INSERT_ID() now returns "the first autogenerated auto_increment value successfully inserted", instead of "the first autogenerated auto_increment value if any row was successfully inserted", see auto_increment.test. Same for mysql_insert_id(), see mysql_client_test.c. - LAST_INSERT_ID() returns the id of the updated row if ON DUPLICATE KEY UPDATE, see auto_increment.test. Same for mysql_insert_id(), see mysql_client_test.c. - LAST_INSERT_ID() does not change if no autogenerated value was successfully inserted (it used to then be 0), see auto_increment.test. - if in INSERT SELECT no autogenerated value was successfully inserted, mysql_insert_id() now returns the id of the last inserted row (it already did this for INSERT VALUES), see mysql_client_test.c. - if INSERT SELECT uses LAST_INSERT_ID(X), mysql_insert_id() now returns X (it already did this for INSERT VALUES), see mysql_client_test.c. - NDB now behaves like other engines wrt SET INSERT_ID: with INSERT IGNORE, the id passed in SET INSERT_ID is re-used until a row succeeds; SET INSERT_ID influences not only the first row now. Additionally, when unlocking a table we check that the thread is not keeping a next_insert_id (as the table is unlocked that id is potentially out-of-date); forgetting about this next_insert_id is done in a new handler::ha_release_auto_increment(). Finally we prepare for engines capable of reserving finite-length intervals of auto_increment values: we store such intervals in THD. The next step (to be done by the replication team in 5.1) is to read those intervals from THD and actually store them in the statement-based binary log. NDB will be a good engine to test that. mysql-test/extra/binlog_tests/binlog.test: Testing that if INSERT_ID is set to a value too big for the column's type, the binlogged INSERT_ID is the truncated value (important if slave has a column of a "wider" numeric type). Testing binlogging of INSERT_ID with INSERT DELAYED, to be sure that we binlog an INSERT_ID event only for the delayed rows which use one. mysql-test/extra/rpl_tests/rpl_insert_id.test: Testcase for BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate statement-based". Testcase for BUG#20341 "stored function inserting into one auto_increment puts bad data in slave". mysql-test/extra/rpl_tests/rpl_loaddata.test: Test that LOAD DATA INFILE sets a value for a future LAST_INSERT_ID(). mysql-test/r/auto_increment.result: behaviour change: when INSERT totally fails (not even succeeds partially and then rolls back), don't change last_insert_id(). Behaviour change: LAST_INSERT_ID() is now the first successfully inserted, autogenerated, id. Behaviour change: if INSERT ON DUPLICATE KEY UPDATE, if the table has auto_increment and a row is updated, then LAST_INSERT_ID() returns the id of this row. mysql-test/r/binlog_row_binlog.result: result update mysql-test/r/binlog_stm_binlog.result: result update mysql-test/r/insert.result: result update mysql-test/r/rpl_insert_id.result: result update mysql-test/r/rpl_loaddata.result: result update mysql-test/r/rpl_ndb_auto_inc.result: ndb's behaviour is now like other engines wrt SET INSERT_ID in a multi-row INSERT: - with INSERT IGNORE: the id passed in SET INSERT_ID is re-used until a row succeeds. - generally, SET INSERT_ID sets the first value and other values are simply computed from this first value, instead of previously where the 2nd and subsequent values where not influenced by SET INSERT_ID; this good change is due to the removal of "thd->next_insert_id=0" from ha_ndbcluster. mysql-test/t/auto_increment.test: A testcase of BUG#19243: if ON DUPLICATE KEY UPDATE updates a row, LAST_INSERT_ID() now returns the id of the row. Test of new behaviour of last_insert_id() when no autogenerated value was inserted, or when only some autogenerated value (not the first of them) was inserted. mysql-test/t/insert.test: testing INSERT IGNORE re-using generated values sql/ha_federated.cc: update for new variables. sql/ha_ndbcluster.cc: handler::auto_increment_column_changed not needed, equivalent to (insert_id_for_cur_row > 0). thd->next_insert_id=0 not needed anymore; it was used to force handler::update_auto_increment() to call ha_ndbcluster::get_auto_increment() for each row of a multi-row INSERT, now this happens naturally because NDB says "I have reserved you *one* value" in get_auto_increment(), so handler::update_auto_increment() calls again for next row. sql/handler.cc: More comments, use of new methods and variables. Hopes to be clearer than current code. thd->prev_insert_id not in THD anymore: it is managed locally by inserters (like mysql_insert()). THD::clear_next_insert_id is now equivalent to handler::next_insert_id > 0. get_auto_increment() reserves an interval of values from the engine, uses this interval for next rows of the statement, until interval is exhausted then it asks for another interval (of a bigger size than the first one; size doubles until reaching 65535 then it stays constant). If doing statement-based binlogging, intervals are remembered in a list for storage in the binlog. For "forced" insert_id values (SET INSERT_ID or replication slave), forced_auto_inc_intervals is non-empty and the handler takes its intervals from there, without calling get_auto_increment(). ha_release_auto_increment() resets the handler's auto_increment variables; it calls release_auto_increment() which is handler-dependent and serves to return to the engine any unused tail of the last used interval. If ending a statement, next_insert_id>0 means that autoinc values have been generated or taken from the master's binlog (in a replication slave) so we clear those values read from binlog, so that next top- or sub- statement does not use them. sql/handler.h: handler::auto_increment_changed can be replaced by (handler::insert_id_for_cur_row > 0). THD::next_insert_id moves into handler (more natural, and prepares for the day when we'll support a single statement inserting into two tables - "multi-table INSERT" like we have UPDATE - will this happen?). This move makes the backup/restore of THD::next_insert_id when entering a substatement unneeded, as each substatement has its own handler objects. sql/item_func.cc: new names for variables. For the setting of what mysql_insert_id() will return to the client, LAST_INSERT_ID(X) used to simply pretend that the generated autoinc value for the current row was X, but this led to having no reliable way to know the really generated value, so we now have a bool: thd->arg_of_last_insert_id_function which enables us to know that LAST_INSERT_ID(X) was called (and then X can be found in thd->first_successful_insert_id_in_prev_stmt). sql/log.cc: new variable names for insert_ids. Removing some unused variables in the slow log. sql/log_event.cc: new variable names, comments. Preparing for when master's won't binlog LAST_INSERT_ID if it was 0. sql/set_var.cc: new variable names. The last change repeats how Bar fixed BUG#20392 "INSERT_ID session variable has weird value" in 5.0. sql/sql_class.cc: new variables for insert_id. In THD::cleanup_after_query() we fix BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate statement-based" (will one want to fix it in 5.0?). Many comments about what stored functions do to auto_increment. In reset|restore_sub_statement_state(), we need to backup less auto_inc variables as some of them have moved to the handler; we backup/restore those which are about the current top- or sub- statement, *not* those about the statement-based binlog (which evolve as the top- and sub-statement execute). Because we split THD::last_insert_id into THD::first_successful_insert_id_in_prev_stmt and THD::auto_inc_intervals_for_binlog (among others), we fix BUG#20341 "stored function inserting into one auto_increment puts bad data in slave": indeed we can afford to not backup/restore THD::auto_inc_intervals_for_binlog (which fixes the bug) while still backing up / restoring THD::first_successful_insert_id_in_prev_stmt (ensuring that the top-level LAST_INSERT_ID() is not affected by INSERTs done by sub-statements, as is desirable and tested in rpl_insert_id.test). sql/sql_class.h: new variables and methods for auto_increment. Some THD members move into handler (those which are really about the table being inserted), some stay in THD (those which are about what a future LAST_INSERT_ID() should return, or about what should be stored into the statement-based binlog). THD::next_insert_id moves to handler::. THD::clear_next_insert_id removed (had become equivalent to next_insert_id > 0). THD::last_insert_id becomes four: THD::first_successful_insert_id_in_cur_stmt, THD::auto_inc_intervals_for_binlog, handler::insert_id_for_cur_row, THD::first_successful_insert_id_in_prev_stmt. THD::current_insert_id becomes: THD::first_successful_insert_id_in_prev_stmt_for_binlog THD::prev_insert_id is removed, handler can just use handler::insert_id_for_cur_row instead (which is more accurate: for the first row, prev_insert_id was set before get_auto_increment was called, so was 0, causing a call to get_auto_increment() for the 2nd row if the 1st row fails; here we don't need the call as insert_id_for_cur_row has the value of the first row). THD::last_insert_id_used becomes: stmt_depends_on_first_row_in_prev_stmt THD::insert_id_used is removed (equivalent to auto_inc_intervals_for_binlog non empty). The interval returned by get_auto_increment() and currently being consumed is handler::auto_inc_interval_for_cur_row. Comments to explain each of them. select_insert::last_insert_id becomes autoinc_value_of_last_inserted_row. sql/sql_insert.cc: the "id" variable is not changed for each row now; it used to compensate for this contradiction: - thd->last_insert_id supposed job was to keep the id of the first row - but it was updated for every row - so mysql_insert() made sure to catch its first value and restore it at the end of stmt. Now THD keeps the first value in first_successful_insert_id_in_cur_stmt, and value of the row in insert_id_for_cur_row. So "id" only serves to fill mysql_insert_id(), as depending on some conditions, "id" must be different values. Prev_insert_id moves from THD to write_record(). We now set LAST_INSERT_ID() in ON DUPLICATE KEY UPDATE too (BUG#19243). In an INSERT DELAYED, we still "reset auto-increment caching" but differently (by calling ha_release_auto_increment()). sql/sql_load.cc: no need to fiddle with "id", THD maintains THD::first_successful_insert_id_in_cur_stmt by itself and correctly now. ha_release_auto_increment() is now (logically) called before we unlock the table. sql/sql_parse.cc: update to new variable names. Assertion that reset_thd_for_next_command() is not called for every substatement of a routine (I'm not against it, but if we do this change, statement-based binlogging needs some adjustments). sql/sql_select.cc: update for new variable names sql/sql_table.cc: next_insert_id not needed in mysql_alter_table(), THD manages. sql/sql_update.cc: update for new variable names. Even though this is UPDATE, an insert id can be generated (by LAST_INSERT_ID(X)) and should be recorded because mysql_insert_id() wants to know about it. sql/structs.h: A class for "discrete" intervals (intervals of integer numbers with a certain increment between them): Discrete_interval, and a class for a list of such intervals: Discrete_intervals_list tests/mysql_client_test.c: tests of behaviour of mysql_insert_id(): there were no such tests, while in our manual we document its behaviour. In comments you'll notice the behaviour changes introduced (there are 5).

WL#3146 "less locking in auto_increment": this is a cleanup patch for our current auto_increment handling: new names for auto_increment variables in THD, new methods to manipulate them (see sql_class.h), some move into handler::, causing less backup/restore work when executing substatements. This makes the logic hopefully clearer, less work is is needed in mysql_insert(). By cleaning up, using different variables for different purposes (instead of one for 3 things...), we fix those bugs, which someone may want to fix in 5.0 too: BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate statement-based" BUG#20341 "stored function inserting into one auto_increment puts bad data in slave" BUG#19243 "wrong LAST_INSERT_ID() after ON DUPLICATE KEY UPDATE" (now if a row is updated, LAST_INSERT_ID() will return its id) and re-fixes: BUG#6880 "LAST_INSERT_ID() value changes during multi-row INSERT" (already fixed differently by Ramil in 4.1) Test of documented behaviour of mysql_insert_id() (there was no test). The behaviour changes introduced are: - LAST_INSERT_ID() now returns "the first autogenerated auto_increment value successfully inserted", instead of "the first autogenerated auto_increment value if any row was successfully inserted", see auto_increment.test.

Test of new behaviour of last_insert_id() when no autogenerated value was inserted, or when only some autogenerated value (not the first of them) was inserted. mysql-test/t/insert.test: testing INSERT IGNORE re-using generated values sql/ha_federated.cc: update for new variables. sql/ha_ndbcluster.cc: handler::auto_increment_column_changed not needed, equivalent to (insert_id_for_cur_row > 0). thd->next_insert_id=0 not needed anymore; it was used to force handler::update_auto_increment() to call ha_ndbcluster::get_auto_increment() for each row of a multi-row INSERT, now this happens naturally because NDB says "I have reserved you *one* value" in get_auto_increment(), so handler::update_auto_increment() calls again for next row. sql/handler.cc: More comments, use of new methods and variables. Hopes to be clearer than current code. thd->prev_insert_id not in THD anymore: it is managed locally by inserters (like mysql_insert()). THD::clear_next_insert_id is now equivalent to handler::next_insert_id > 0. get_auto_increment() reserves an interval of values from the engine, uses this interval for next rows of the statement, until interval is exhausted then it asks for another interval (of a bigger size than the first one; size doubles until reaching 65535 then it stays constant). If doing statement-based binlogging, intervals are remembered in a list for storage in the binlog. For "forced" insert_id values (SET INSERT_ID or replication slave), forced_auto_inc_intervals is non-empty and the handler takes its intervals from there, without calling get_auto_increment(). ha_release_auto_increment() resets the handler's auto_increment variables; it calls release_auto_increment() which is handler-dependent and serves to return to the engine any unused tail of the last used interval. If ending a statement, next_insert_id>0 means that autoinc values have been generated or taken from the master's binlog (in a replication slave) so we clear those values read from binlog, so that next top- or sub- statement does not use them. sql/handler.h: handler::auto_increment_changed can be replaced by (handler::insert_id_for_cur_row > 0). THD::next_insert_id moves into handler (more natural, and prepares for the day when we'll support a single statement inserting into two tables - "multi-table INSERT" like we have UPDATE - will this happen?). This move makes the backup/restore of THD::next_insert_id when entering a substatement unneeded, as each substatement has its own handler objects. sql/item_func.cc: new names for variables. For the setting of what mysql_insert_id() will return to the client, LAST_INSERT_ID(X) used to simply pretend that the generated autoinc value for the current row was X, but this led to having no reliable way to know the really generated value, so we now have a bool: thd->arg_of_last_insert_id_function which enables us to know that LAST_INSERT_ID(X) was called (and then X can be found in thd->first_successful_insert_id_in_prev_stmt). sql/log.cc: new variable names for insert_ids. Removing some unused variables in the slow log. sql/log_event.cc: new variable names, comments. Preparing for when master's won't binlog LAST_INSERT_ID if it was 0. sql/set_var.cc: new variable names. The last change repeats how Bar fixed BUG#20392 "INSERT_ID session variable has weird value" in 5.0. sql/sql_class.cc: new variables for insert_id. In THD::cleanup_after_query() we fix BUG#20339 "stored procedure using LAST_INSERT_ID() does not replicate statement-based" (will one want to fix it in 5.0?). Many comments about what stored functions do to auto_increment. In reset|restore_sub_statement_state(), we need to backup less auto_inc variables as some of them have moved to the handler; we backup/restore those which are about the current top- or sub- statement, *not* those about the statement-based binlog (which evolve as the top- and sub-statement execute). Because we split THD::last_insert_id into THD::first_successful_insert_id_in_prev_stmt and THD::auto_inc_intervals_for_binlog (among others), we fix BUG#20341 "stored function inserting into one auto_increment puts bad data in slave": indeed we can afford to not backup/restore THD::auto_inc_intervals_for_binlog (which fixes the bug) while still backing up / restoring THD::first_successful_insert_id_in_prev_stmt (ensuring that the top-level LAST_INSERT_ID() is not affected by INSERTs done by sub-statements, as is desirable and tested in rpl_insert_id.test). sql/sql_class.h: new variables and methods for auto_increment. Some THD members move into handler (those which are really about the table being inserted), some stay in THD (those which are about what a future LAST_INSERT_ID() should return, or about what should be stored into the statement-based binlog). THD::next_insert_id moves to handler::. THD::clear_next_insert_id removed (had become equivalent to next_insert_id > 0). THD::last_insert_id becomes four: THD::first_successful_insert_id_in_cur_stmt, THD::auto_inc_intervals_for_binlog, handler::insert_id_for_cur_row, THD::first_successful_insert_id_in_prev_stmt. THD::current_insert_id becomes: THD::first_successful_insert_id_in_prev_stmt_for_binlog THD::prev_insert_id is removed, handler can just use handler::insert_id_for_cur_row instead (which is more accurate: for the first row, prev_insert_id was set before get_auto_increment was called, so was 0, causing a call to get_auto_increment() for the 2nd row if the 1st row fails; here we don't need the call as insert_id_for_cur_row has the value of the first row). THD::last_insert_id_used becomes: stmt_depends_on_first_row_in_prev_stmt THD::insert_id_used is removed (equivalent to auto_inc_intervals_for_binlog non empty). The interval returned by get_auto_increment() and currently being consumed is handler::auto_inc_interval_for_cur_row. Comments to explain each of them. select_insert::last_insert_id becomes autoinc_value_of_last_inserted_row. sql/sql_insert.cc: the "id" variable is not changed for each row now; it used to compensate for this contradiction: - thd->last_insert_id supposed job was to keep the id of the first row - but it was updated for every row - so mysql_insert() made sure to catch its first value and restore it at the end of stmt. Now THD keeps the first value in first_successful_insert_id_in_cur_stmt, and value of the row in insert_id_for_cur_row. So "id" only serves to fill mysql_insert_id(), as depending on some conditions, "id" must be different values. Prev_insert_id moves from THD to write_record(). We now set LAST_INSERT_ID() in ON DUPLICATE KEY UPDATE too (BUG#19243). In an INSERT DELAYED, we still "reset auto-increment caching" but differently (by calling ha_release_auto_increment()). sql/sql_load.cc: no need to fiddle with "id", THD maintains THD::first_successful_insert_id_in_cur_stmt by itself and correctly now. ha_release_auto_increment() is now (logically) called before we unlock the table. sql/sql_parse.cc: update to new variable names. Assertion that reset_thd_for_next_command() is not called for every substatement of a routine (I'm not against it, but if we do this change, statement-based binlogging needs some adjustments). sql/sql_select.cc: update for new variable names sql/sql_table.cc: next_insert_id not needed in mysql_alter_table(), THD manages. sql/sql_update.cc: update for new variable names. Even though this is UPDATE, an insert id can be generated (by LAST_INSERT_ID(X)) and should be recorded because mysql_insert_id() wants to know about it. sql/structs.h: A class for "discrete" intervals (intervals of integer numbers with a certain increment between them): Discrete_interval, and a class for a list of such intervals: Discrete_intervals_list tests/mysql_client_test.c: tests of behaviour of mysql_insert_id(): there were no such tests, while in our manual we document its behaviour. In comments you'll notice the behaviour changes introduced (there are 5).

Manual merge from 5.0-rpl, of fixes for: 1) BUG#25507 "multi-row insert delayed + auto increment causes duplicate key entries on slave" (two concurrrent connections doing multi-row INSERT DELAYED to insert into an auto_increment column, caused replication slave to stop with "duplicate key error" (and binlog was wrong), and BUG#26116 "If multi-row INSERT DELAYED has errors, statement-based binlogging breaks" (the binlog was not accounting for all rows inserted, or slave could stop). The fix is that: in statement-based binlogging, a multi-row INSERT DELAYED is silently converted to a non-delayed INSERT. This is supposed to not affect many 5.1 users as in 5.1, the default binlog format is "mixed", which does not have the bug (the bug is only with binlog_format=STATEMENT). We should document how the system delayed_insert thread decides of its binlog format (which is not modified by this patch): this decision is taken when the thread is created and holds until it is terminated (is not affected by any later change via SET GLOBAL BINLOG_FORMAT). It is also not affected by the binlog format of the connection which issues INSERT DELAYED (this binlog format does not affect how the row will be binlogged). If one wants to change the binlog format of its server with SET GLOBAL BINLOG_FORMAT, it should do FLUSH TABLES to be sure all delayed_insert threads terminate and thus new threads are created, taking into account the new format. 2) BUG#24432 "INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values". When in an INSERT ON DUPLICATE KEY UPDATE, using an autoincrement column, we inserted some autogenerated values and also updated some rows, some autogenerated values were not used (for example, even if 10 was the largest autoinc value in the table at the start of the statement, 12 could be the first autogenerated value inserted by the statement, instead of 11). One autogenerated value was lost per updated row. Led to exhausting the range of the autoincrement column faster. Bug introduced by fix of BUG#20188; present since 5.0.24 and 5.1.12. This bug breaks replication from a pre-5.0.24/pre-5.1.12 master. But the present bugfix, as it makes INSERT ON DUP KEY UPDATE behave like pre-5.0.24/pre-5.1.12, breaks replication from a [5.0.24,5.0.34]/[5.1.12,5.1.15] master to a fixed (5.0.36/5.1.16) slave! To warn users against this when they upgrade their slave, as agreed with the support team, we add code for a fixed slave to detect that it is connected to a buggy master in a situation (INSERT ON DUP KEY UPDATE into autoinc column) likely to break replication, in which case it cannot replicate so stops and prints a message to the slave's error log and to SHOW SLAVE STATUS. For 5.0.36->[5.0.24,5.0.34] replication or 5.1.16->[5.1.12,5.1.15] replication we cannot warn as master does not know the slave's version (but we always recommended to users to have slave at least as new as master). As agreed with support, I have asked for an alert to be put into the MySQL Network Monitoring and Advisory Service. 3) note that I'll re-enable rpl_insert_id as soon as 5.1-rpl gets the changes from the main 5.1. BitKeeper/deleted/.del-rpl_insert_delayed.result: Delete: mysql-test/r/rpl_insert_delayed.result mysql-test/extra/rpl_tests/rpl_insert_delayed.test: tests for BUG#25507 (lauch many concurrent INSERT DELAYED into an auto_inc column and see if they cause duplicates) and BUG#26116 (see if one error at first row on master makes the slave's data incorrect). It is then incorporated into a statement-based and mixed binlogging test, and into a row-based test. It is in fact mysql-test/t/rpl_insert_delayed.test from 5.0, renamed and extended to test BUG#25507. mysql-test/extra/rpl_tests/rpl_insert_id.test: manual merge of test for BUG#24432 "INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values" from 5.0 mysql-test/r/rpl_insert_id.result: result update (it automerged from 5.0, contrary to the test file) mysql-test/r/rpl_known_bugs_detection.result: result update (binlog event sizes differ from 5.0) mysql-test/t/disabled.def: rpl_insert_id tests statement-based replication of INSERT ON DUPLICATE KEY UPDATE. This type of INSERT had BUG#24432, which is fixed in 5.1.16; we made the slave detect if it is connected to a <5.1.16 master and if so refuse to replicate. The problem is that this 5.1-rpl tree, even though it will produce the 5.1.16 release, still has a 5.1.15 version in configure.in. Thus rpl_insert_id fails. So I disable it. As soon as the 5.1-rpl tree gets the changesets from the main 5.1, its version will change to 5.1.16 and so I'll be able to re-enable the test. mysql-test/t/rpl_known_bugs_detection.test: only in statement-based; row-based has no bug so test would fail. sql/slave.cc: slave_print_msg(ERROR_LEVEL) calls my_error(ER_UNKNOWN_ERROR); so, for our my_printf_error(), which has a nicer message than this my_error(), to have any effect, it must be called before slave_print_msg() sql/sql_insert.cc: manual merge from 5.0 of a piece of the fixes for BUG#24432 "INSERT... ON DUPLICATE KEY UPDATE skips auto_increment values" BUG#25507 "multi-row insert delayed + auto increment causes duplicate key entries on slave" BUG#26116 "If multi-row INSERT DELAYED has errors, statement-based binlogging breaks". The other pieces (e.g. log_event.cc) automerged from 5.0. mysql-test/r/rpl_row_insert_delayed.result: result mysql-test/r/rpl_stm_insert_delayed.result: result. Note how "mixed" and "statement" insert different data in the table. mysql-test/t/rpl_row_insert_delayed.test: wrapper to test INSERT DELAYED binlogging in row-based mode mysql-test/t/rpl_stm_insert_delayed.test: wrapper to test INSERT DELAYED binlogging in statement-based and mixed mode

fixes after merge. Updates to test's results. We now reset the THD members related to auto_increment+binlog in MYSQL_LOG::write(). This is better than in THD::cleanup_after_query(), which was not able to distinguish between SELECT myfunc1(),myfunc2() and INSERT INTO t SELECT myfunc1(),myfunc2() from a binlogging point of view. Rows_log_event::exec_event() now calls lex_start() instead of mysql_init_query() because the latter now does too much (it resets the binlog format). mysql-test/extra/rpl_tests/rpl_insert_id.test: fix after merge mysql-test/mysql-test-run.pl: -v does not bring useful information when running valgrind; I remove it; if you think it's useful add it back. mysql-test/r/binlog_stm_mix_innodb_myisam.result: Position columns of SHOW BINLOG EVENTS are replaced by # (more robust if the size of an event changes). mysql-test/r/rpl_insert_id.result: fix after merge mysql-test/r/rpl_loaddata.result: The binlog positions change, because one event disappeared; indeed there was this in the binlog (in the current 5.1!): SET INSERT_ID=2; SET INSERT_ID=1; SET TIMESTAMP=1152540671; load data LOCAL INFILE '/tmp/SQL_LOAD_MB-1-2' INTO table t1; Two INSERT_ID events, useless and a bug. Goes away afer cleaning up auto_increment handling. mysql-test/r/rpl_switch_stm_row_mixed.result: INSERT_ID=5 appears, it's a consequence of having merged the fix for BUG#20341 "stored function inserting into one auto_increment puts bad data in slave". In mixed mode, if one substatement of a stored procedure requires row-based, the entire procedure uses row-based (was already true for stored functions); this is a consequence of not doing the resetting of binlog format inside lock_tables() (which didn't work with how the slave thread executes row-based binlog events). mysql-test/t/rpl_switch_stm_row_mixed.test: removing the multi-row delayed insert because in RBR the number of events which it generates, is not repeatable (probably depends on how the delayed thread groups rows, i.e. dependent on timing). sql/ha_partition.cc: update to new prototype sql/ha_partition.h: update to new prototype of the handler:: method. sql/handler.cc: after-merge fixes (manually merging part which was hard to merge in fmtool) sql/log.cc: When we write to the binary log, THD's parameters which influenced this write are reset: stmt_depends_on_first_successful_insert_id_in_prev_stmt and auto_inc_intervals_in_cur_stmt_for_binlog. This is so that future writes are not influenced by those and can write their own values. As a consequence, when we don't write to the binlog we do not reset. This is to abide by the rule that in a complex statement (using triggers etc), the first top- or substatement to generate auto_increment ids wins their writing to the binlog (that writing may be done by the statement itself or by the caller); so for example for INSERT INTO t SELECT myfunc() where myfunc() inserts into auto_increment and INSERT INTO t does not, myfunc() will fill auto_inc_intervals_in_cur_stmt_for_binlog, which will not be reset when myfunc() ends, then INSERT INTO t will write to the binlog and thus write the preserved auto_inc_intervals_in_cur_stmt_for_binlog. sql/log_event.cc: mysql_init_query() does too much now to be called in Rows_log_event::exec_event (it call mysql_reset_thd_for_next_command() which may switch the binlog format now). It's ok to call it in Table_map_log_event::exec_event() but its call must be before setting the binlog format to "row". sql/sql_base.cc: Resetting the binlog format in lock_tables() was a bad idea of mine; it causes problems in execution of row-based binlog events, where the thread sets the binlog format by itself and does not want a next lock_tables() to reset the binlog format. It is also misleading, for a function named lock_tables(), to reset the binlog format. As a consequence of this change, in mixed binlogging mode, a routine is logged either entirely statement-based or entirely row-based, we don't switch in the middle (this was already true for prelocked routines, now it's also true for stored procedures). sql/sql_class.cc: resetting of auto_increment variables used for binlogging is now done when writing to the binary log, no need to do the resetting at the end of the statement. It is also more correct this way; consider SELECT myfunc1(),myfunc2(); where both functions insert into the same auto_increment column. Binlogging is done in 2 events: "SELECT myfunc1()" and "SELECT myfunc2()". So each of those needs to have, in binlog, the INSERT_ID which it inserted. But as the 2 function calls are executed under prelocked mode, the old code didn't reset auto_inc_intervals_in_cur_stmt_for_binlog after the first SELECT was binlogged, and so the INSERT_ID of the first SELECT was binlogged for the first SELECT and (wrong) also for the 2nd SELECT event. stmt_depends_on_first_... has the same logic. sql/sql_class.h: clearer comment sql/sql_delete.cc: unneeded #ifdef. As we temporarily change the binlog format to "statement" before calling mysql_delete(), we must restore it afterwards. sql/sql_insert.cc: after-merge fixes. No need to reset auto_inc_intervals_in_cur_stmt_for_binlog for every row in the delayed insert system thread, because we already reset it when writing to the binlog. sql/sql_parse.cc: unneeded #ifdef

Fix for BUG#20188 "REPLACE or ON DUPLICATE KEY UPDATE in auto_increment breaks binlog": if slave's table had a higher auto_increment counter than master's (even though all rows of the two tables were identical), then in some cases, REPLACE and INSERT ON DUPLICATE KEY UPDATE failed to replicate statement-based (it inserted different values on slave from on master). write_record() contained a "thd->next_insert_id=0" to force an adjustment of thd->next_insert_id after the update or replacement. But it is this assigment introduced indeterminism of the statement on the slave, thus the bug. For ON DUPLICATE, we replace that assignment by a call to handler::adjust_next_insert_id_after_explicit_value() which is deterministic (does not depend on slave table's autoinc counter). For REPLACE, this assignment can simply be removed (as REPLACE can't insert a number larger than thd->next_insert_id). We also move a too early restore_auto_increment() down to when we really know that we can restore the value. mysql-test/r/rpl_insert_id.result: result update, without the bugfix, slave's "3 350" were "4 350". mysql-test/t/rpl_insert_id.test: test for BUG#20188 "REPLACE or ON DUPLICATE KEY UPDATE in auto_increment breaks binlog". There is, in this order: - a test of the bug for the case of REPLACE - a test of basic ON DUPLICATE KEY UPDATE functionality which was not tested before - a test of the bug for the case of ON DUPLICATE KEY UPDATE sql/handler.cc: the adjustment of next_insert_id if inserting a big explicit value, is moved to a separate method to be used elsewhere. sql/handler.h: see handler.cc sql/sql_insert.cc: restore_auto_increment() means "I know I won't use this autogenerated autoincrement value, you are free to reuse it for next row". But we were calling restore_auto_increment() in the case of REPLACE: if write_row() fails inserting the row, we don't know that we won't use the value, as we are going to try again by doing internally an UPDATE of the existing row, or a DELETE of the existing row and then an INSERT. So I move restore_auto_increment() further down, when we know for sure we failed all possibilities for the row. Additionally, in case of REPLACE, we don't need to reset THD::next_insert_id: the value of thd->next_insert_id will be suitable for the next row. In case of ON DUPLICATE KEY UPDATE, resetting thd->next_insert_id is also wrong (breaks statement-based binlog), but cannot simply be removed, as thd->next_insert_id must be adjusted if the explicit value exceeds it. We now do the adjustment by calling handler::adjust_next_insert_id_after_explicit_value() (which, contrary to thd->next_insert_id=0, does not depend on the slave table's autoinc counter, and so is deterministic).

This bug breaks replication from a pre-5.0.24 master. But the present bugfix, as it makes INSERT ON DUP KEY UPDATE behave like pre-5.0.24, breaks replication from a [5.0.24,5.0.34] master to a fixed (5.0.36) slave! To warn users against this when they upgrade their slave, as agreed with the support team, we add code for a fixed slave to detect that it is connected to a buggy master in a situation (INSERT ON DUP KEY UPDATE into autoinc column) likely to break replication, in which case it cannot replicate so stops and prints a message to the slave's error log and to SHOW SLAVE STATUS.

As agreed with support, I'll also ask for an alert to be put into the MySQL Network Monitoring and Advisory Service. mysql-test/r/rpl_insert_id.result: results to check the bugfix; without the bugfix, you would see, in master and slave: "3,2" instead of "2,2" for the INSERT VALUES testcase, "11,6,..." instead of "6,6,..." for the INSERT SELECT testcase. mysql-test/t/rpl_insert_id.test: testing that BUG#24432 is fixed sql/log_event.cc: A trick to force the master to pretend it is old and features BUG#24432. To do fast lookups in the list of known bugs by version, we compute the 3 X.Y.Z numbers from the master's version string and cache that into a new member Format_description_log_event::server_version_split. We do this computation in the event's two constructors. A simple prevention against buffer overrun when reading the master's version from a binlog event (assume the event is corrupted on disk, and so the version string on disk is longer than ST_SERVER_VER_LEN (50), then we would not get a closing 0 at the end of the class member. sql/log_event.h: new member to hold the "split server version" (3 numbers X.Y.Z), and a method to compute this from the version string. sql/slave.cc: a function which tells, based on master's version (as found in the Format_description event in the relay log being executed), if master can have a certain bug. This function uses a list of bug_id / first_version_with_bug / first_version_with_fix. If the test is positive, a short error message is put into SHOW SLAVE STATUS, and a verbose message is put into the slave's error log. The caller is expected to stop the slave in this case. sql/slave.h: new function to test if the replication master has a bug sql/sql_insert.cc: Fix for BUG#24432:t he reason was a misplaced restore_auto_increment() (misplaced when fixing BUG#20188). Indeed, when updating the row, it is clear that the autogenerated auto_increment value will not be used for this row (and if by "chance" the autoinc value present in the updated row is >= to the not used autogenerated value, adjust_next_insert_id_after_explicit_value() will fix next_insert_id). We also add code for a fixed slave to detect that it is connected to a buggy master (in which case it cannot replicate so stops). mysql-test/r/rpl_known_bugs_detection.result: see that SHOW SLAVE STATUS prints information that slave found a bug in master, and does not execute the dangerous event (table stays empty). mysql-test/t/rpl_known_bugs_detection-master.opt: pass debug symbol to make the master pretend it has BUG#24432 mysql-test/t/rpl_known_bugs_detection.test: new test to see if bug detection by slave works

BUG#21726: Incorrect result with multiple invocations of LAST_INSERT_ID Non-upper-level INSERTs (the ones in the body of stored procedure, stored function, or trigger) into a table that have AUTO_INCREMENT column didn't affected the result of LAST_INSERT_ID() on this level. The problem was introduced with the fix of bug 6880, which in turn was introduced with the fix of bug 3117, where current insert_id value was remembered on the first call to LAST_INSERT_ID() (bug 3117) and was returned from that function until it was reset before the next _upper-level_ statement (bug 6880). The fix for bug#21726 brings back the behaviour of version 4.0, and implements the following: remember insert_id value at the beginning of the statement or expression (which at that point equals to the first insert_id value generated by the previous statement), and return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID. Thus, the value returned by LAST_INSERT_ID() is not affected by values generated by current statement, nor by LAST_INSERT_ID(expr) calls in this statement.

The problem was introduced with the fix of bug 6880, which in turn was introduced with the fix of bug 3117, where current insert_id value was remembered on the first call to LAST_INSERT_ID() (bug 3117) and was returned from that function until it was reset before the next _upper-level_ statement (bug 6880).

fixes after merge. Updates to test's results. We now reset the THD members related to auto_increment+binlog in MYSQL_LOG::write(). This is better than in THD::cleanup_after_query(), which was not able to distinguish between SELECT myfunc1(),myfunc2() and INSERT INTO t SELECT myfunc1(),myfunc2() from a binlogging point of view. Rows_log_event::exec_event() now calls lex_start() instead of mysql_init_query() because the latter now does too much (it resets the binlog format). mysql-test/extra/rpl_tests/rpl_insert_id.test: fix after merge mysql-test/mysql-test-run.pl: -v does not bring useful information when running valgrind; I remove it; if you think it's useful add it back. mysql-test/r/binlog_stm_mix_innodb_myisam.result: Position columns of SHOW BINLOG EVENTS are replaced by # (more robust if the size of an event changes). mysql-test/r/rpl_insert_id.result: fix after merge mysql-test/r/rpl_loaddata.result: The binlog positions change, because one event disappeared; indeed there was this in the binlog (in the current 5.1!): SET INSERT_ID=2; SET INSERT_ID=1; SET TIMESTAMP=1152540671; load data LOCAL INFILE '/tmp/SQL_LOAD_MB-1-2' INTO table t1; Two INSERT_ID events, useless and a bug. Goes away afer cleaning up auto_increment handling. mysql-test/r/rpl_switch_stm_row_mixed.result: INSERT_ID=5 appears, it's a consequence of having merged the fix for BUG#20341 "stored function inserting into one auto_increment puts bad data in slave". In mixed mode, if one substatement of a stored procedure requires row-based, the entire procedure uses row-based (was already true for stored functions); this is a consequence of not doing the resetting of binlog format inside lock_tables() (which didn't work with how the slave thread executes row-based binlog events). mysql-test/t/rpl_switch_stm_row_mixed.test: removing the multi-row delayed insert because in RBR the number of events which it generates, is not repeatable (probably depends on how the delayed thread groups rows, i.e. dependent on timing). sql/ha_partition.cc: update to new prototype sql/ha_partition.h: update to new prototype of the handler:: method. sql/handler.cc: after-merge fixes (manually merging part which was hard to merge in fmtool) sql/log.cc: When we write to the binary log, THD's parameters which influenced this write are reset: stmt_depends_on_first_successful_insert_id_in_prev_stmt and auto_inc_intervals_in_cur_stmt_for_binlog. This is so that future writes are not influenced by those and can write their own values. As a consequence, when we don't write to the binlog we do not reset. This is to abide by the rule that in a complex statement (using triggers etc), the first top- or substatement to generate auto_increment ids wins their writing to the binlog (that writing may be done by the statement itself or by the caller); so for example for INSERT INTO t SELECT myfunc() where myfunc() inserts into auto_increment and INSERT INTO t does not, myfunc() will fill auto_inc_intervals_in_cur_stmt_for_binlog, which will not be reset when myfunc() ends, then INSERT INTO t will write to the binlog and thus write the preserved auto_inc_intervals_in_cur_stmt_for_binlog. sql/log_event.cc: mysql_init_query() does too much now to be called in Rows_log_event::exec_event (it call mysql_reset_thd_for_next_command() which may switch the binlog format now). It's ok to call it in Table_map_log_event::exec_event() but its call must be before setting the binlog format to "row". sql/sql_base.cc: Resetting the binlog format in lock_tables() was a bad idea of mine; it causes problems in execution of row-based binlog events, where the thread sets the binlog format by itself and does not want a next lock_tables() to reset the binlog format. It is also misleading, for a function named lock_tables(), to reset the binlog format. As a consequence of this change, in mixed binlogging mode, a routine is logged either entirely statement-based or entirely row-based, we don't switch in the middle (this was already true for prelocked routines, now it's also true for stored procedures). sql/sql_class.cc: resetting of auto_increment variables used for binlogging is now done when writing to the binary log, no need to do the resetting at the end of the statement. It is also more correct this way; consider SELECT myfunc1(),myfunc2(); where both functions insert into the same auto_increment column. Binlogging is done in 2 events: "SELECT myfunc1()" and "SELECT myfunc2()". So each of those needs to have, in binlog, the INSERT_ID which it inserted. But as the 2 function calls are executed under prelocked mode, the old code didn't reset auto_inc_intervals_in_cur_stmt_for_binlog after the first SELECT was binlogged, and so the INSERT_ID of the first SELECT was binlogged for the first SELECT and (wrong) also for the 2nd SELECT event. stmt_depends_on_first_... has the same logic. sql/sql_class.h: clearer comment sql/sql_delete.cc: unneeded #ifdef. As we temporarily change the binlog format to "statement" before calling mysql_delete(), we must restore it afterwards. sql/sql_insert.cc: after-merge fixes. No need to reset auto_inc_intervals_in_cur_stmt_for_binlog for every row in the delayed insert system thread, because we already reset it when writing to the binlog. sql/sql_parse.cc: unneeded #ifdef

Fixing problems I identified in my auto_increment work pushed in July (as part of the auto_increment cleanup of WL#3146; let's not be sad, that monster push still removed serious bugs): one problem with INSERT DELAYED (unexpected interval releases), one with stored functions (wrong auto_inc binlogging). These bugs were not released. mysql-test/extra/binlog_tests/binlog_insert_delayed.test: more tests of binlogging of INSERT DELAYED: with multi-row INSERTs. I identified why sleeps are needed to get a repeatable row-based binlogged: because without sleeps rows sometimes get groupped and so generate different row based events. mysql-test/extra/rpl_tests/rpl_foreign_key.test: don't forget to drop tables on slave too, otherwise it leaves an orphan innodb table leading to rpl_insert_id failing sometimes (like in pushbuild "sapsrv2 -max"). mysql-test/extra/rpl_tests/rpl_insert_id.test: testing that if some statement does not update any row, it does not pollute the auto_inc binlog variables of the next statement; the test has to use stored procedures because with plain statements, mysql_reset_thd_for_next_command() does the resetting (and thus there is no problem); mysql_reset_thd_for_next_command() is not called inside routines. mysql-test/r/binlog_row_binlog.result: result additions mysql-test/r/binlog_statement_insert_delayed.result: result additions mysql-test/r/binlog_stm_binlog.result: result additions mysql-test/r/rpl_insert_id.result: result additions mysql-test/r/rpl_loaddata.result: With the change to log.cc reverted, the result changes and is better: the change to log.cc had caused some INSERT_ID events to disappear though they were necessary (but testsuite could not catch that because it's single-threaded). mysql-test/r/rpl_ndb_insert_ignore.result: NDB is now like other engines regarding INSERT IGNORE: autoincrement values which caused a duplicate key are re-used for next row, not lost. rpl_ndb_insert_ignore.result is now identical to rpl_insert_ignore.result. sql/log.cc: LOAD DATA INFILE is binlogged as several events, and the last of them must have the auto_inc id. So it's wrong to reset the auto_inc id after every binlog write (because then it's lost after the first event of LOAD DATA INFILE and so missing for the last one)/ Another problem: MYSQL_LOG::write() is not always called (for example if no row was updated), so we were missing reset in some cases. sql/sp_head.cc: SELECT func1(),func2() generates two binlog events, so needs to clear auto_increment binlog variables after each binlog event (it would be more natural to clear them in the log write code, but LOAD DATA INFILE would suffer from this see the cset comment for log.cc). Without the clearing, the problem is: > exec func1() >> call cleanup_after_query() (which does not clear our vars here) >> binlog SELECT func1() < > exec func2() and so SELECT func2() is binlogged with the auto_inc of SELECT func1(). sql/sql_class.cc: after every statement we should clear auto_inc variables used for binlogging, except if this was a function/trigger (in which case it may be "INSERT SELECT func()", where the cleanup_after_query() executed in func() should not reset the auto_inc binlog variables as they'll be necessary when binlogging the INSERT SELECT later). sql/sql_insert.cc: - as INSERT DELAYED uses the same TABLE object as the delayed_insert system thread, we should not call ha_release_auto_increment() from INSERT DELAYED (and btw it's logical as we reserve nothing as we don't perform the insert). Calling the function caused us to release values being used by the delayed_insert thread. So I do the call only if this is a non-DELAYED INSERT. - Assuming two INSERT DELAYED which get grouped by the delayed_insert thread, the second may use values reserved by the first, which is ok per se, but is a problem in statement-based binlogging: the 2nd INSERT gets binlogged with the "interval start" value of the first INSERT (=> duplicate error in slave). - no reason to ha_release_auto_increment() after every inserted row in INSERT SELECT; more efficient to do it only when the statement ends sql/sql_parse.cc: a comment

I identified why sleeps are needed to get a repeatable row-based binlogged: because without sleeps rows sometimes get groupped and so generate different row based events. mysql-test/extra/rpl_tests/rpl_foreign_key.test: don't forget to drop tables on slave too, otherwise it leaves an orphan innodb table leading to rpl_insert_id failing sometimes (like in pushbuild "sapsrv2 -max"). mysql-test/extra/rpl_tests/rpl_insert_id.test: testing that if some statement does not update any row, it does not pollute the auto_inc binlog variables of the next statement; the test has to use stored procedures because with plain statements, mysql_reset_thd_for_next_command() does the resetting (and thus there is no problem); mysql_reset_thd_for_next_command() is not called inside routines. mysql-test/r/binlog_row_binlog.result: result additions mysql-test/r/binlog_statement_insert_delayed.result: result additions mysql-test/r/binlog_stm_binlog.result: result additions mysql-test/r/rpl_insert_id.result: result additions mysql-test/r/rpl_loaddata.result: With the change to log.cc reverted, the result changes and is better: the change to log.cc had caused some INSERT_ID events to disappear though they were necessary (but testsuite could not catch that because it's single-threaded). mysql-test/r/rpl_ndb_insert_ignore.result: NDB is now like other engines regarding INSERT IGNORE: autoincrement values which caused a duplicate key are re-used for next row, not lost. rpl_ndb_insert_ignore.result is now identical to rpl_insert_ignore.result. sql/log.cc: LOAD DATA INFILE is binlogged as several events, and the last of them must have the auto_inc id. So it's wrong to reset the auto_inc id after every binlog write (because then it's lost after the first event of LOAD DATA INFILE and so missing for the last one)/ Another problem: MYSQL_LOG::write() is not always called (for example if no row was updated), so we were missing reset in some cases. sql/sp_head.cc: SELECT func1(),func2() generates two binlog events, so needs to clear auto_increment binlog variables after each binlog event (it would be more natural to clear them in the log write code, but LOAD DATA INFILE would suffer from this see the cset comment for log.cc). Without the clearing, the problem is: > exec func1() >> call cleanup_after_query() (which does not clear our vars here) >> binlog SELECT func1() < > exec func2() and so SELECT func2() is binlogged with the auto_inc of SELECT func1(). sql/sql_class.cc: after every statement we should clear auto_inc variables used for binlogging, except if this was a function/trigger (in which case it may be "INSERT SELECT func()", where the cleanup_after_query() executed in func() should not reset the auto_inc binlog variables as they'll be necessary when binlogging the INSERT SELECT later). sql/sql_insert.cc: - as INSERT DELAYED uses the same TABLE object as the delayed_insert system thread, we should not call ha_release_auto_increment() from INSERT DELAYED (and btw it's logical as we reserve nothing as we don't perform the insert). Calling the function caused us to release values being used by the delayed_insert thread. So I do the call only if this is a non-DELAYED INSERT. - Assuming two INSERT DELAYED which get grouped by the delayed_insert thread, the second may use values reserved by the first, which is ok per se, but is a problem in statement-based binlogging: the 2nd INSERT gets binlogged with the "interval start" value of the first INSERT (=> duplicate error in slave). - no reason to ha_release_auto_increment() after every inserted row in INSERT SELECT; more efficient to do it only when the statement ends sql/sql_parse.cc: a comment
