This is a backport of the patch for MySQL Bug#50574. Adding a SPATIAL INDEX on non-geometrical columns caused a segmentation fault when the table was subsequently inserted into. A test was added in mysql_prepare_create_table to explicitly check whether non-geometrical columns are used in a spatial index, and throw an error if so. For MySQL 5.5 and later, a new and more meaningful error message was introduced. For 5.1, we (re-)use an existing error code. --- mysql-test/r/gis.result | 33 +++++++++++++++++++++++++++++++++ mysql-test/t/gis.test | 47 +++++++++++++++++++++++++++++++++++++++++++++++ sql/sql_table.cc | 22 ++++++++++++++++------ 3 files changed, 96 insertions(+), 6 deletions(-) diff --git a/mysql-test/r/gis.result b/mysql-test/r/gis.result index a9beb9631ae..151d0cfffa1 100644 --- a/mysql-test/r/gis.result +++ b/mysql-test/r/gis.result @@ -1034,4 +1034,37 @@ p NULL NULL drop table t1; +CREATE TABLE t0 (a BINARY(32) NOT NULL); +CREATE SPATIAL INDEX i on t0 (a); +ERROR HY000: Incorrect arguments to SPATIAL INDEX +INSERT INTO t0 VALUES (1); +CREATE TABLE t1( +col0 BINARY NOT NULL, +col2 TIMESTAMP, +SPATIAL INDEX i1 (col0) +) ENGINE=MyISAM; +ERROR HY000: Incorrect arguments to SPATIAL INDEX +CREATE TABLE t1 ( +col0 BINARY NOT NULL, +col2 TIMESTAMP +) ENGINE=MyISAM; +CREATE SPATIAL INDEX idx0 ON t1(col0); +ERROR HY000: Incorrect arguments to SPATIAL INDEX +ALTER TABLE t1 ADD SPATIAL INDEX i1 (col0); +ERROR HY000: Incorrect arguments to SPATIAL INDEX +CREATE TABLE t2 ( +col0 INTEGER NOT NULL, +col1 POINT, +col2 POINT +); +CREATE SPATIAL INDEX idx0 ON t2 (col1, col2); +ERROR HY000: Incorrect arguments to SPATIAL INDEX +CREATE TABLE t3 ( +col0 INTEGER NOT NULL, +col1 POINT, +col2 LINESTRING, +SPATIAL INDEX i1 (col1, col2) +); +ERROR HY000: Incorrect arguments to SPATIAL INDEX +DROP TABLE t0, t1, t2; End of 5.1 tests diff --git a/mysql-test/t/gis.test b/mysql-test/t/gis.test index bdbbfc7c064..b50df062d7e 100644 --- a/mysql-test/t/gis.test +++ b/mysql-test/t/gis.test @@ -754,4 +754,51 @@ insert into t1 values (geomfromtext("point(1 0)")); select * from (select polygon(t1.a) as p from t1 order by t1.a) d; drop table t1; +# +# Bug#11767480 - SPATIAL INDEXES ON NON-SPATIAL COLUMNS CAUSE CRASHES. +# +CREATE TABLE t0 (a BINARY(32) NOT NULL); +--error ER_WRONG_ARGUMENTS +CREATE SPATIAL INDEX i on t0 (a); +INSERT INTO t0 VALUES (1); + +--error ER_WRONG_ARGUMENTS +CREATE TABLE t1( + col0 BINARY NOT NULL, + col2 TIMESTAMP, + SPATIAL INDEX i1 (col0) +) ENGINE=MyISAM; + +# Test other ways to add indices +CREATE TABLE t1 ( + col0 BINARY NOT NULL, + col2 TIMESTAMP +) ENGINE=MyISAM; + +--error ER_WRONG_ARGUMENTS +CREATE SPATIAL INDEX idx0 ON t1(col0); + +--error ER_WRONG_ARGUMENTS +ALTER TABLE t1 ADD SPATIAL INDEX i1 (col0); + +CREATE TABLE t2 ( + col0 INTEGER NOT NULL, + col1 POINT, + col2 POINT +); + +--error ER_WRONG_ARGUMENTS +CREATE SPATIAL INDEX idx0 ON t2 (col1, col2); + +--error ER_WRONG_ARGUMENTS +CREATE TABLE t3 ( + col0 INTEGER NOT NULL, + col1 POINT, + col2 LINESTRING, + SPATIAL INDEX i1 (col1, col2) +); + +# cleanup +DROP TABLE t0, t1, t2; + --echo End of 5.1 tests diff --git a/sql/sql_table.cc b/sql/sql_table.cc index b919ea9eae7..c5fc037a49e 100644 --- a/sql/sql_table.cc +++ b/sql/sql_table.cc @@ -1,4 +1,4 @@ -/* Copyright 2000-2008 MySQL AB, 2008 Sun Microsystems, Inc. +/* Copyright 2000-2011, Oracle and/or its affiliates.

This has been masked by the fact that MySQL would roll back any PREPARED transaction on shutdown, in the spirit of Bug #12161 Xa recovery and client disconnection. [mysql-test-run] do_shutdown_server: Interpret --shutdown_server 0 as a request to kill the server immediately without initiating a shutdown procedure. xid_cache_insert(): Initialize XID_STATE::rm_error in order to avoid a bogus error message on XA ROLLBACK of a recovered PREPARED transaction. innobase_commit_by_xid(), innobase_rollback_by_xid(): Free the InnoDB transaction object after rolling back a PREPARED transaction. trx_get_trx_by_xid(): Only consider transactions whose trx->is_prepared flag is set. The MySQL layer seems to prevent attempts to roll back connected transactions that are in the PREPARED state from another connection, but it is better to play it safe. The is_prepared flag was introduced in the InnoDB Plugin. trx_n_prepared: A new counter, counting the number of InnoDB transactions in the PREPARED state. logs_empty_and_mark_files_at_shutdown(): On shutdown, allow trx_n_prepared transactions to exist in the system. trx_undo_free_prepared(), trx_free_prepared(): New functions, to free the memory objects of PREPARED transactions on shutdown. This is not needed in the built-in InnoDB, because it would collect all allocated memory on shutdown. The InnoDB Plugin needs this because of innodb_use_sys_malloc. trx_sys_close(): Invoke trx_free_prepared() on all remaining transactions. --- client/mysqltest.cc | 12 ++-- mysql-test/suite/innodb/r/innodb_bug59641.result | 57 ++++++++++++++++++ mysql-test/suite/innodb/t/innodb_bug59641.test | 66 ++++++++++++++++++++ .../suite/innodb_plugin/r/innodb_bug59641.result | 57 ++++++++++++++++++ .../suite/innodb_plugin/t/innodb_bug59641.test | 70 ++++++++++++++++++++++ sql/sql_class.cc | 1 + storage/innobase/handler/ha_innodb.cc | 6 +- storage/innobase/include/trx0trx.h | 5 ++ storage/innobase/log/log0log.c | 9 +-- storage/innobase/trx/trx0trx.c | 11 ++++ storage/innodb_plugin/ChangeLog | 7 +++ storage/innodb_plugin/handler/ha_innodb.cc | 6 +- storage/innodb_plugin/include/trx0trx.h | 11 ++++ storage/innodb_plugin/include/trx0undo.h | 9 +++ storage/innodb_plugin/log/log0log.c | 9 +-- storage/innodb_plugin/trx/trx0sys.c | 10 ++++ storage/innodb_plugin/trx/trx0trx.c | 70 +++++++++++++++++++++- storage/innodb_plugin/trx/trx0undo.c | 28 +++++++++ 18 files changed, 425 insertions(+), 19 deletions(-) create mode 100644 mysql-test/suite/innodb/r/innodb_bug59641.result create mode 100644 mysql-test/suite/innodb/t/innodb_bug59641.test create mode 100644 mysql-test/suite/innodb_plugin/r/innodb_bug59641.result create mode 100644 mysql-test/suite/innodb_plugin/t/innodb_bug59641.test diff --git a/client/mysqltest.cc b/client/mysqltest.cc index 52c76b8c68e..a1813838a24 100644 --- a/client/mysqltest.cc +++ b/client/mysqltest.cc @@ -4461,13 +4461,14 @@ static int my_kill(int pid, int sig) command called command DESCRIPTION - shutdown [] + shutdown_server [] */ void do_shutdown_server(struct st_command *command) { - int timeout=60, pid;

The problem was that having the SELECT privilege any column of the mysql.proc table by mistake allowed the user to see the definition of all routines (using SHOW CREATE PROCEDURE/FUNCTION and SHOW PROCEDURE/FUNCTION CODE). This patch fixes the problem by making sure that those commands are only allowed if the user has the SELECT privilege on the mysql.proc table itself.

ON WINDOWS Backport of the fix to 5.0 (to be null-merged to 5.1). Moved the test into the main test suite. Made mysql-test-run.pl to not use symlinks for sdtdata as the symlinks are now properly recognized by secure_file_priv. Made sure the paths in load_file(), LOAD DATA and SELECT .. INTO OUTFILE that are checked against secure_file_priv in a correct way similarly to 5.1 by the extended is_secure_file_path() backport before the comparison. Added an extensive test with all the variants of upper/lower case, slash/backslash and case sensitivity. Added few comments to the code. --- mysql-test/mysql-test-run.pl | 14 ++--- mysql-test/r/secure_file_priv_win.result | 38 +++++++++++++ mysql-test/t/secure_file_priv_win-master.opt | 1 + mysql-test/t/secure_file_priv_win.test | 79 ++++++++++++++++++++++++++++ mysys/my_symlink.c | 17 +++++- sql/item_strfunc.cc | 3 +- sql/mysql_priv.h | 2 + sql/mysqld.cc | 58 ++++++++++++++++++++ sql/sql_class.cc | 3 +- sql/sql_load.cc | 48 ++++++++--------- 10 files changed, 223 insertions(+), 40 deletions(-) create mode 100644 mysql-test/r/secure_file_priv_win.result create mode 100644 mysql-test/t/secure_file_priv_win-master.opt create mode 100644 mysql-test/t/secure_file_priv_win.test diff --git a/mysql-test/mysql-test-run.pl b/mysql-test/mysql-test-run.pl index f0100593516..f43cadd3784 100755 --- a/mysql-test/mysql-test-run.pl +++ b/mysql-test/mysql-test-run.pl @@ -2412,17 +2412,9 @@ sub setup_vardir() { mkpath("$data_dir/test");

The problem was that wrong structure of mysql.event was not detected and the server continued to use wrongly-structured data. The fix is to check the structure of mysql.event after opening before any use. That makes operations with events more strict -- some operations that might work before throw errors now. That seems to be Ok. Another side-effect of the patch is that if mysql.event is corrupted, unrelated DROP DATABASE statements issue an SQL warning about inability to open mysql.event table. --- mysql-test/r/events_1.result | 106 ++++++++++++++++++++++++++---------- mysql-test/r/events_restart.result | 3 + mysql-test/t/events_1.test | 109 ++++++++++++++++++++++++++++--------- mysql-test/t/events_restart.test | 2 + sql/event_db_repository.cc | 8 +++ 5 files changed, 172 insertions(+), 56 deletions(-) diff --git a/mysql-test/r/events_1.result b/mysql-test/r/events_1.result index e7b645f5556..e0c137ea877 100644 --- a/mysql-test/r/events_1.result +++ b/mysql-test/r/events_1.result @@ -1,3 +1,4 @@ +call mtr.add_suppression("Column count of mysql.event is wrong.

To fix this, we make mysqlbinlog not to complain when it has not printed the FD event, is outputing in base64, but is decoding the rows. --- client/mysqlbinlog.cc | 3 ++- mysql-test/r/mysqlbinlog_base64.result | 10 ++++++++++ mysql-test/t/mysqlbinlog_base64.test | 29 +++++++++++++++++++++++++++++ 3 files changed, 41 insertions(+), 1 deletion(-) diff --git a/client/mysqlbinlog.cc b/client/mysqlbinlog.cc index 30a8bddc17c..f451e28de86 100644 --- a/client/mysqlbinlog.cc +++ b/client/mysqlbinlog.cc @@ -951,7 +951,8 @@ Exit_status process_event(PRINT_EVENT_INFO *print_event_info, Log_event *ev, passed --short-form, because --short-form disables printing row events. */ - if (!print_event_info->printed_fd_event && !short_form) + if (!print_event_info->printed_fd_event && !short_form && + opt_base64_output_mode != BASE64_OUTPUT_DECODE_ROWS) { const char* type_str= ev->get_type_str(); if (opt_base64_output_mode == BASE64_OUTPUT_NEVER) diff --git a/mysql-test/r/mysqlbinlog_base64.result b/mysql-test/r/mysqlbinlog_base64.result index c5e1e2f8ca1..72d49c16cc8 100644 --- a/mysql-test/r/mysqlbinlog_base64.result +++ b/mysql-test/r/mysqlbinlog_base64.result @@ -109,3 +109,13 @@ count(*) 35840 drop table t1; drop table t2; +RESET MASTER; +USE test; +SET @old_binlog_format= @@binlog_format; +SET SESSION binlog_format=ROW; +CREATE TABLE t1(c1 INT); +INSERT INTO t1 VALUES (1); +FLUSH LOGS; +DROP TABLE t1; +SET SESSION binlog_format= @old_binlog_format; +RESET MASTER; diff --git a/mysql-test/t/mysqlbinlog_base64.test b/mysql-test/t/mysqlbinlog_base64.test index fb21e28fdcb..3d3444cea1c 100644 --- a/mysql-test/t/mysqlbinlog_base64.test +++ b/mysql-test/t/mysqlbinlog_base64.test @@ -71,3 +71,32 @@ select count(*) from t2; --remove_file $MYSQLTEST_VARDIR/tmp/mysqlbinlog_base64.sql drop table t1; drop table t2; + +# +# BUG#12354268 +# +# This test verifies that using --start-position with DECODE-ROWS +# does not make mysqlbinlog to output an error stating that it +# does not contain any FD event. +# + +RESET MASTER; +USE test; +SET @old_binlog_format= @@binlog_format; +SET SESSION binlog_format=ROW; +CREATE TABLE t1(c1 INT); +--let $master_binlog= query_get_value(SHOW MASTER STATUS, File, 1) +--let $master_pos= query_get_value(SHOW MASTER STATUS, Position, 1) +--let $MYSQLD_DATADIR= `SELECT @@datadir` + +INSERT INTO t1 VALUES (1); + +FLUSH LOGS; + +--disable_result_log +--exec $MYSQL_BINLOG --base64-output=DECODE-ROWS --start-position=$master_pos -v $MYSQLD_DATADIR/$master_binlog +--enable_result_log + +DROP TABLE t1; +SET SESSION binlog_format= @old_binlog_format; +RESET MASTER; -- cgit v1.2.1 From d939820001eb84cc064397928019975ef1f6c002 Mon Sep 17 00:00:00 2001 From: Luis Soares Date: Fri, 6 May 2011 00:46:53 +0100 Subject: BUG#11762616: BUG#55229: 'POSTION' Fix for all "postion" in Oracle files (s/postion/position).

In sql_class.cc, 'row_count', of type 'ha_rows', was used as last argument for ER_TRUNCATED_WRONG_VALUE_FOR_FIELD which is "Incorrect %-.32s value: '%-.128s' for column '%.192s' at row %ld". So 'ha_rows' was used as 'long'. On SPARC32 Solaris builds, 'long' is 4 bytes and 'ha_rows' is 'longlong' i.e. 8 bytes. So the printf-like code was reading only the first 4 bytes. Because the CPU is big-endian, 1LL is 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x01 so the first four bytes yield 0. So the warning message had "row 0" instead of "row 1" in test outfile_loaddata.test: -Warning 1366 Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 1 +Warning 1366 Incorrect string value: '\xE1\xE2\xF7' for column 'b' at row 0 All error-messaging functions which internally invoke some printf-life function are potential candidate for such mistakes. One apparently easy way to catch such mistakes is to use ATTRIBUTE_FORMAT (from my_attribute.h). But this works only when call site has both: a) the format as a string literal b) the types of arguments. So: func(ER(ER_BLAH), 10); will silently not be checked, because ER(ER_BLAH) is not known at compile time (it is known at run-time, and depends on the chosen language). And func("%s", a va_list argument); has the same problem, as the *real* type of arguments is not known at this site at compile time (it's known in some caller). Moreover, func(ER(ER_BLAH)); though possibly correct (if ER(ER_BLAH) has no '%' markers), will not compile (gcc says "error: format not a string literal and no format arguments"). Consequences: 1) ATTRIBUTE_FORMAT is here added only to functions which in practice take "string literal" formats: "my_error_reporter" and "print_admin_msg". 2) it cannot be added to the other functions: my_error(), push_warning_printf(), Table_check_intact::report_error(), general_log_print(). To do a one-time check of functions listed in (2), the following "static code analysis" has been done: 1) replace my_error(ER_xxx, arguments for substitution in format) with the equivalent my_printf_error(ER_xxx,ER(ER_xxx), arguments for substitution in format), so that we have ER(ER_xxx) and the arguments *in the same call site* 2) add ATTRIBUTE_FORMAT to push_warning_printf(), Table_check_intact::report_error(), general_log_print() 3) replace ER(xxx) with the hard-coded English text found in errmsg.txt (like: ER(ER_UNKNOWN_ERROR) is replaced with "Unknown error"), so that a call site has the format as string literal 4) this way, ATTRIBUTE_FORMAT can effectively do its job 5) compile, fix errors detected by ATTRIBUTE_FORMAT 6) revert steps 1-2-3. The present patch has no compiler error when submitted again to the static code analysis above. It cannot catch all problems though: see Field::set_warning(), in which a call to push_warning_printf() has a variable error (thus, not replacable by a string literal); I checked set_warning() calls by hand though. See also WL 5883 for one proposal to avoid such bugs from appearing again in the future. The issues fixed in the patch are: a) mismatch in types (like 'int' passed to '%ld') b) more arguments passed than specified in the format. This patch resolves mismatches by changing the type/number of arguments, not by changing error messages of sql/share/errmsg.txt. The latter would be wrong, per the following old rule: errmsg.txt must be as stable as possible; no insertions or deletions of messages, no changes of type or number of printf-like format specifiers, are allowed, as long as the change impacts a message already released in a GA version. If this rule is not followed: - Connectors, which use error message numbers, will be confused (by insertions/deletions of messages) - using errmsg.sys of MySQL 5.1.n with mysqld of MySQL 5.1.(n+1) could produce wrong messages or crash; such usage can easily happen if installing 5.1.(n+1) while /etc/my.cnf still has --language=/path/to/5.1.n/xxx; or if copying mysqld from 5.1.(n+1) into a 5.1.n installation. When fixing b), I have verified that the superfluous arguments were not used in the format in the first 5.1 GA (5.1.30 'bteam@astra04-20081114162938-z8mctjp6st27uobm'). Had they been used, then passing them today, even if the message doesn't use them anymore, would have been necessary, as explained above. include/my_getopt.h: this function pointer is used only with "string literal" formats, so we can add ATTRIBUTE_FORMAT. mysql-test/collections/default.experimental: test should pass now sql/derror.cc: by having a format as string literal, ATTRIBUTE_FORMAT check becomes effective. sql/events.cc: Change justified by the following excerpt from sql/share/errmsg.txt: ER_EVENT_SAME_NAME eng "Same old and new event name" ER_EVENT_SET_VAR_ERROR eng "Error during starting/stopping of the scheduler.

However, very rarely, master_pos_wait reports a timeout. This happens because the time set for master_pos_wait to wait was too small (6 seconds). On slow test env this could be a problem. We fix this by setting the timeout inline with the one used in sync_slave_with_master (300 seconds). In addition we refactored the test case and refined some comments. --- mysql-test/suite/rpl/r/rpl_relayspace.result | 10 +++---- mysql-test/suite/rpl/t/rpl_relayspace.test | 42 ++++++++++++++++++---------- 2 files changed, 32 insertions(+), 20 deletions(-) diff --git a/mysql-test/suite/rpl/r/rpl_relayspace.result b/mysql-test/suite/rpl/r/rpl_relayspace.result index f12f177ff7c..fb21540aa31 100644 --- a/mysql-test/suite/rpl/r/rpl_relayspace.result +++ b/mysql-test/suite/rpl/r/rpl_relayspace.result @@ -1,6 +1,6 @@ include/master-slave.inc [connection master] -stop slave; +include/stop_slave.inc create table t1 (a int); drop table t1; create table t1 (a int); @@ -8,10 +8,8 @@ drop table t1; reset slave; start slave io_thread; include/wait_for_slave_param.inc [Slave_IO_State] -stop slave io_thread; +include/stop_slave_io.inc reset slave; -start slave; -select master_pos_wait('master-bin.001',200,6)=-1; -master_pos_wait('master-bin.001',200,6)=-1 -0 +include/start_slave.inc +include/assert.inc [Assert that master_pos_wait does not timeout nor it returns NULL] include/rpl_end.inc diff --git a/mysql-test/suite/rpl/t/rpl_relayspace.test b/mysql-test/suite/rpl/t/rpl_relayspace.test index bb34ec25bcd..fc33d6bc0ba 100644 --- a/mysql-test/suite/rpl/t/rpl_relayspace.test +++ b/mysql-test/suite/rpl/t/rpl_relayspace.test @@ -2,8 +2,9 @@ # to force the deadlock after one event. source include/master-slave.inc; +--let $master_log_file= query_get_value(SHOW MASTER STATUS, File, 1) connection slave; -stop slave; +--source include/stop_slave.inc connection master; # This will generate a master's binlog > 10 bytes create table t1 (a int); @@ -19,20 +20,33 @@ let $slave_param_value= Waiting for the slave SQL thread to free enough relay lo source include/wait_for_slave_param.inc; # A bug caused the I/O thread to refuse stopping. -stop slave io_thread; +--source include/stop_slave_io.inc reset slave; -start slave; -# The I/O thread stops filling the relay log when -# it's >10b.

Symptoms: re-execution of prepared statement (or statement in a stored routine) which read from one of I_S tables and which in order to fill this I_S table had to open a view led to increasing memory consumption. What happened in this situation was that during the process of view opening for purpose of I_S filling view-related structures (like its LEX) were allocated on persistent MEM_ROOT of prepared statement (or stored routine). Since this MEM_ROOT is not freed until prepared statement deallocation (or expulsion of stored routine from the cache) and code responsible for filling I_S is not able to re-use results of view opening from previous executions this allocation ended up in memory hogging. This patch solves the problem by ensuring that when a view opened for the purpose of I_S filling all its structures are allocated on non-persistent runtime MEM_ROOT. This is achieved by activating a temporary Query_arena bound to this MEM_ROOT. Since this step makes impossible linking of view structures into LEX of our prepared statement (or stored routine statement) this patch also changes code filling I_S table to install a proxy LEX before trying to open a view or a table. Consequently some code which was responsible for backing-up/restoring parts of LEX when view/table was opened during filling of I_S table became redundant and was removed. This patch doesn't contain test case for this bug as it is hard to test memory hogging in our test suite. --- sql/sql_show.cc | 320 +++++++++++++++++++++++++++++++------------------------- 1 file changed, 180 insertions(+), 140 deletions(-) diff --git a/sql/sql_show.cc b/sql/sql_show.cc index 5b835096042..310ec3b8e4f 100644 --- a/sql/sql_show.cc +++ b/sql/sql_show.cc @@ -2428,12 +2428,11 @@ bool schema_table_store_record(THD *thd, TABLE *table) } -int make_table_list(THD *thd, SELECT_LEX *sel, - LEX_STRING *db_name, LEX_STRING *table_name) +static int make_table_list(THD *thd, SELECT_LEX *sel, + LEX_STRING *db_name, LEX_STRING *table_name) { Table_ident *table_ident; table_ident= new Table_ident(thd, *db_name, *table_name, 1); - sel->init_query(); if (!sel->add_table_to_list(thd, table_ident, 0, 0, TL_READ)) return 1; return 0; @@ -3003,79 +3002,179 @@ make_table_name_list(THD *thd, List *table_names, LEX *lex, /** - @brief Fill I_S table for SHOW COLUMNS|INDEX commands + Fill I_S table with data obtained by performing full-blown table open. + + @param thd Thread handler. + @param is_show_fields_or_keys Indicates whether it is a legacy SHOW + COLUMNS or SHOW KEYS statement. + @param table TABLE object for I_S table to be filled. + @param schema_table I_S table description structure. + @param orig_db_name Database name. + @param orig_table_name Table name. + @param open_tables_state_backup Open_tables_state object which is used + to save/restore original status of + variables related to open tables state. + + @retval FALSE - Success. + @retval TRUE - Failure. +*/ - @param[in] thd thread handler - @param[in] tables TABLE_LIST for I_S table - @param[in] schema_table pointer to I_S structure - @param[in] open_tables_state_backup pointer to Open_tables_state object - which is used to save|restore original - status of variables related to - open tables state +static bool +fill_schema_table_by_open(THD *thd, bool is_show_fields_or_keys, + TABLE *table, ST_SCHEMA_TABLE *schema_table, + LEX_STRING *orig_db_name, + LEX_STRING *orig_table_name, + Open_tables_state *open_tables_state_backup) +{ + Query_arena i_s_arena(thd->mem_root, + Query_arena::CONVENTIONAL_EXECUTION), + backup_arena, *old_arena; + LEX *old_lex= thd->lex, temp_lex, *lex; + LEX_STRING db_name, table_name; + TABLE_LIST *table_list; + bool result= true; - @return Operation status - @retval 0 success - @retval 1 error -*/ + /* + When a view is opened its structures are allocated on a permanent + statement arena and linked into the LEX tree for the current statement + (this happens even in cases when view is handled through TEMPTABLE + algorithm). -static int -fill_schema_show_cols_or_idxs(THD *thd, TABLE_LIST *tables, - ST_SCHEMA_TABLE *schema_table, - Open_tables_state *open_tables_state_backup) -{ - LEX *lex= thd->lex; - bool res; - LEX_STRING tmp_lex_string, tmp_lex_string1, *db_name, *table_name; - enum_sql_command save_sql_command= lex->sql_command; - TABLE_LIST *show_table_list= tables->schema_select_lex->table_list.first; - TABLE *table= tables->table; - int error= 1; - DBUG_ENTER("fill_schema_show"); + To prevent this process from unnecessary hogging of memory in the permanent + arena of our I_S query and to avoid damaging its LEX we use temporary + arena and LEX for table/view opening. + + Use temporary arena instead of statement permanent arena.

Attempt to update an InnoDB temporary table under LOCK TABLES led to assertion failure in both debug and production builds if this temporary table was explicitly locked for READ. The same scenario works fine for MyISAM temporary tables. The assertion failure was caused by discrepancy between lock that was requested on the rows of temporary table at LOCK TABLES time and by update operation. Since SQL-layer requested a read-lock at LOCK TABLES time InnoDB engine assumed that upcoming statements which are going to be executed under LOCK TABLES will only read table and therefore should acquire only S-lock. An update operation broken this assumption by requesting X-lock. Possible approaches to fixing this problem are: 1) Skip locking of temporary tables as locking doesn't make any sense for connection-local objects. 2) Prohibit changing of temporary table locked by LOCK TABLES ... READ. Unfortunately both of these approaches have drawbacks which make them unviable for stable versions of server. So this patch takes another approach and changes code in such way that LOCK TABLES for a temporary table will always request write lock. In 5.1 version of this patch switch from read lock to write lock is done inside of InnoDBs handler methods as doing it on SQL-layer causes compatibility troubles with FLUSH TABLES WITH READ LOCK. mysql-test/suite/innodb/r/innodb_mysql.result: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". mysql-test/suite/innodb/t/innodb_mysql.test: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". mysql-test/suite/innodb_plugin/r/innodb_mysql.result: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". mysql-test/suite/innodb_plugin/t/innodb_mysql.test: Added test for bug #11762012 - "54553: INNODB ASSERTS IN HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK". storage/innobase/handler/ha_innodb.cc: Assume that a temporary table locked by LOCK TABLES can be updated even if it was only locked for read and therefore an X-lock should be always requested for such tables. storage/innodb_plugin/handler/ha_innodb.cc: Assume that a temporary table locked by LOCK TABLES can be updated even if it was only locked for read and therefore an X-lock should be always requested for such tables. --- mysql-test/suite/innodb/r/innodb_mysql.result | 18 +++++++++++++++- mysql-test/suite/innodb/t/innodb_mysql.test | 25 +++++++++++++++++++--- .../suite/innodb_plugin/r/innodb_mysql.result | 16 ++++++++++++++ mysql-test/suite/innodb_plugin/t/innodb_mysql.test | 20 +++++++++++++++++ storage/innobase/handler/ha_innodb.cc | 12 +++++++++-- storage/innodb_plugin/handler/ha_innodb.cc | 12 +++++++++-- 6 files changed, 95 insertions(+), 8 deletions(-) diff --git a/mysql-test/suite/innodb/r/innodb_mysql.result b/mysql-test/suite/innodb/r/innodb_mysql.result index fa26b8b1d01..a7feb692091 100644 --- a/mysql-test/suite/innodb/r/innodb_mysql.result +++ b/mysql-test/suite/innodb/r/innodb_mysql.result @@ -2639,7 +2639,6 @@ COUNT(*) 1537 SET SESSION sort_buffer_size = DEFAULT;

A CREATE IF NOT EXIST on an event that existed and was enabled caused multiple instances of the event to run. Disabling the event didn't help. If the event was dropped, the event stopped running, but when created again, multiple instances of the event were still running. The only way to get out of this situation was to restart the server. The problem was that Event_db_repository::create_event() didn't return enough information to discriminate between situation when event didn't exist and was created and when event did exist and was not created (but a warning was emitted). As result in the latter case event was added to in-memory queue of events second time. And this led to unwarranted multiple executions of the same event.

These clients denote the end of the string with the end of the packet. Although this goes against the documented (see MySQL Internals ClientServer Protocol wiki) description of the protocol, these old clients still need to be supported. The solution is to support the documented and actual behavior of the clients. If a client is using the pre-4.1 version of the protocol, the end of a string in the authentication packet can either be denoted with a null character or by the end of the packet. This restores backwards compatibility with old clients implementing either the documented or actual behavior. sql/password.c: The scrambled message, as provided by the user, might not be properly null terminated. If this is the case, uninitialized memory past the end of the buffer could theoretically be accessed. To ensure that this is never the case, copy the scrambled message over to a null terminated auxiliar buffer. sql/sql_connect.cc: Use different execution paths to read strings depending on the protocol being used. If version 4.0 of the protocol is used, end of string can be denoted with a NUL character or by the end of the packet. If there are not enough bytes left after the current position of the buffer to satisfy the current string, the string is considered to be empty. This is required because old clients do not send the password string field if the password is empty. --- sql/password.c | 32 +++++++------- sql/sql_connect.cc | 121 +++++++++++++++++++++++++++++++++++++++++++---------- 2 files changed, 115 insertions(+), 38 deletions(-) diff --git a/sql/password.c b/sql/password.c index 9204c660b77..29a501986f4 100644 --- a/sql/password.c +++ b/sql/password.c @@ -204,21 +204,16 @@ void scramble_323(char *to, const char *message, const char *password) } -/* - Check scrambled message - Used in pre 4.1 password handling - SYNOPSIS - check_scramble_323() - scrambled scrambled message to check. - message original random message which was used for scrambling; must - be exactly SCRAMBLED_LENGTH_323 bytes long and - NULL-terminated. - hash_pass password which should be used for scrambling - All params are IN. +/** + Check scrambled message.

Removed the affected tests from the experimental list. --- configure.in | 3 ++- mysql-test/collections/default.experimental | 3 --- sql/mysqld.cc | 19 ++++++++++++------- 3 files changed, 14 insertions(+), 11 deletions(-) diff --git a/configure.in b/configure.in index 3603512f3f1..901515fecb6 100644 --- a/configure.in +++ b/configure.in @@ -2061,7 +2061,8 @@ AC_CHECK_FUNCS(alarm bfill bmove bsearch bzero \ sighold sigset sigthreadmask port_create sleep \ snprintf socket stpcpy strcasecmp strerror strsignal strnlen strpbrk strstr \ strtol strtoll strtoul strtoull tell tempnam thr_setconcurrency vidattr \ - posix_fallocate backtrace backtrace_symbols backtrace_symbols_fd printstack) + posix_fallocate backtrace backtrace_symbols backtrace_symbols_fd printstack \ + fedisableexcept) # # diff --git a/mysql-test/collections/default.experimental b/mysql-test/collections/default.experimental index 941606a37a5..8883acfa606 100644 --- a/mysql-test/collections/default.experimental +++ b/mysql-test/collections/default.experimental @@ -46,6 +46,3 @@ parts.partition_mgm_lc1_ndb # joro : NDB tests marked as experiment parts.partition_mgm_lc2_ndb # joro : NDB tests marked as experimental as agreed with bochklin parts.partition_syntax_ndb # joro : NDB tests marked as experimental as agreed with bochklin parts.partition_value_ndb # joro : NDB tests marked as experimental as agreed with bochklin -main.gis-rtree # svoj: due to BUG#11749418 -main.type_float # svoj: due to BUG#11749418 -main.type_newdecimal # svoj: due to BUG#11749418 diff --git a/sql/mysqld.cc b/sql/mysqld.cc index 2d1290bf88a..36f195e6232 100644 --- a/sql/mysqld.cc +++ b/sql/mysqld.cc @@ -171,12 +171,12 @@ static void getvolumeID(BYTE *volumeName); int initgroups(const char *,unsigned int); #endif -#if defined(__FreeBSD__) && defined(HAVE_IEEEFP_H) +#if defined(__FreeBSD__) && defined(HAVE_IEEEFP_H) && !defined(HAVE_FEDISABLEEXCEPT) #include #ifdef HAVE_FP_EXCEPT // Fix type conflict typedef fp_except fp_except_t; #endif -#endif /* __FreeBSD__ && HAVE_IEEEFP_H */ +#endif /* __FreeBSD__ && HAVE_IEEEFP_H && !HAVE_FEDISABLEEXCEPT */ #ifdef HAVE_SYS_FPU_H /* for IRIX to use set_fpc_csr() */ #include @@ -202,19 +202,24 @@ extern "C" my_bool reopen_fstreams(const char *filename, inline void setup_fpu() { -#if defined(__FreeBSD__) && defined(HAVE_IEEEFP_H) +#if defined(__FreeBSD__) && defined(HAVE_IEEEFP_H) && !defined(HAVE_FEDISABLEEXCEPT) /* We can't handle floating point exceptions with threads, so disable this on freebsd - Don't fall for overflow, underflow,divide-by-zero or loss of precision + Don't fall for overflow, underflow,divide-by-zero or loss of precision. + fpsetmask() is deprecated in favor of fedisableexcept() in C99. */ -#if defined(__i386__) +#if defined(FP_X_DNML) fpsetmask(~(FP_X_INV | FP_X_DNML | FP_X_OFL | FP_X_UFL | FP_X_DZ | FP_X_IMP)); #else fpsetmask(~(FP_X_INV | FP_X_OFL | FP_X_UFL | FP_X_DZ | FP_X_IMP)); -#endif /* __i386__ */ -#endif /* __FreeBSD__ && HAVE_IEEEFP_H */ +#endif /* FP_X_DNML */ +#endif /* __FreeBSD__ && HAVE_IEEEFP_H && !HAVE_FEDISABLEEXCEPT */ + +#ifdef HAVE_FEDISABLEEXCEPT + fedisableexcept(FE_ALL_EXCEPT); +#endif #ifdef HAVE_FESETROUND /* Set FPU rounding mode to "round-to-nearest" */ -- cgit v1.2.1 From 21428cc0717b19e9c429328b7271902c6b6dfb38 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marko=20M=C3=A4kel=C3=A4?= Date: Wed, 29 Jun 2011 16:48:41 +0300 Subject: Bug #12612184 BLOB debug code cleanup: Forgot an #if around the declaration of trx_assert_recovered(). --- storage/innodb_plugin/include/trx0sys.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/storage/innodb_plugin/include/trx0sys.h b/storage/innodb_plugin/include/trx0sys.h index ed62375797a..78bb6fc349b 100644 --- a/storage/innodb_plugin/include/trx0sys.h +++ b/storage/innodb_plugin/include/trx0sys.h @@ -284,6 +284,7 @@ ibool trx_in_trx_list( /*============*/ trx_t* in_trx);/*!< in: trx */ +#if defined UNIV_DEBUG || defined UNIV_BLOB_LIGHT_DEBUG /***********************************************************//** Assert that a transaction has been recovered. @return TRUE */ @@ -293,6 +294,7 @@ trx_assert_recovered( /*=================*/ trx_id_t trx_id) /*!< in: transaction identifier */ __attribute__((warn_unused_result)); +#endif /* UNIV_DEBUG || UNIV_BLOB_LIGHT_DEBUG */ /*****************************************************************//** Updates the offset information about the end of the MySQL binlog entry which corresponds to the transaction just being committed.

Any ALTER EVENT statement on a disabled event enabled it back (unless this ALTER EVENT statement explicitly disabled the event). The problem was that during processing of an ALTER EVENT statement value of status field was overwritten unconditionally even if new value was not specified explicitly. As a consequence this field was set to default value for status which corresponds to ENABLE. The solution is to check if status field was explicitly specified in ALTER EVENT statement before assigning new value to status field. mysql-test/r/events_bugs.result: test's result for Bug#11764334 was added. mysql-test/t/events_bugs.test: new test for Bug#11764334 was added. sql/event_db_repository.cc: mysql_event_fill_row() was modified: set value for status field in events tables only in case if statement CREATE EVENT is being processed or if this value was set in ALTER EVENT statement. Event_db_repository::create_event was modified: removed redundant setting of status field after return from call to mysql_event_fill_row(). sql/event_parse_data.h: Event_parse_data structure was modified: added flag status_changed that is set to true if status's value was changed in ALTER EVENT statement. sql/sql_yacc.yy: Set flag status_changed if status was set in ALTER EVENT statement. --- mysql-test/r/events_bugs.result | 16 +++++++++++++++- mysql-test/t/events_bugs.test | 15 +++++++++++++++ sql/event_db_repository.cc | 13 +++++++++---- sql/event_parse_data.cc | 11 +++++++---- sql/event_parse_data.h | 1 + sql/sql_yacc.yy | 3 +++ 6 files changed, 50 insertions(+), 9 deletions(-) diff --git a/mysql-test/r/events_bugs.result b/mysql-test/r/events_bugs.result index 740f94fb061..73cb4d58cdc 100644 --- a/mysql-test/r/events_bugs.result +++ b/mysql-test/r/events_bugs.result @@ -419,7 +419,7 @@ SET TIME_ZONE= '+04:00';

Attempt to execute any statement on such a table resulted in parsing error reported. Since this included DROP TRIGGER and DROP TABLE statements (actually, the latter was allowed but was not functioning properly for such tables) it was impossible to fix the problem without manual operations on .TRG and .TRN files in data directory. The problem was that failure to parse trigger body (due to 5.0-only syntax) when opening trigger file for a table prevented the table from being open. This made all operations on the table impossible (except DROP TABLE which due to peculiarity in its implementation dropped the table but left trigger files around). This patch solves this problem by silencing error which occurs when we parse trigger body during table open. Error message is preserved for the future use and table is marked as having a broken trigger. We also try to analyze parse tree to recover trigger name, which will be needed in order to drop the broken trigger. DML statements which invoke triggers on the table marked as having broken trigger are prohibited and emit saved error message. The same happens for DDL which change triggers except DROP TRIGGER and DROP TABLE which try their best to do what was requested. Table becomes no longer marked as having broken trigger when last such trigger is dropped. mysql-test/r/trigger-compat.result: Add results for test case for bug#45235 mysql-test/t/trigger-compat.test: Add test case for bug#45235. sql/sp_head.cc: Added protection against MEM_ROOT double restoring to sp_head::restore_thd_mem_root() method. Since this method can be sometimes called twice during parsing of stored routine (the first time during normal flow of parsing, and the second time when a syntax error is detected) we need to shortcut execution of the method to avoid damaging MEM_ROOT by the second consecutive call to this method. sql/sql_trigger.cc: Added error handler Deprecated_trigger_syntax_handler to catch non-OOM errors during parsing of trigger body. Added handling of parse errors into method Table_triggers_list::check_n_load(). sql/sql_trigger.h: Added new members to handle broken triggers and error messages. --- mysql-test/r/trigger-compat.result | 98 +++++++++++++++++++++ mysql-test/r/trigger.result | 4 +- mysql-test/t/trigger-compat.test | 174 +++++++++++++++++++++++++++++++++++++ sql/sp_head.cc | 15 ++++ sql/sql_parse.cc | 8 +- sql/sql_trigger.cc | 148 ++++++++++++++++++++++++++++--- sql/sql_trigger.h | 35 +++++++- 7 files changed, 464 insertions(+), 18 deletions(-) diff --git a/mysql-test/r/trigger-compat.result b/mysql-test/r/trigger-compat.result index 2bcd919e0db..d456ce8253f 100644 --- a/mysql-test/r/trigger-compat.result +++ b/mysql-test/r/trigger-compat.result @@ -43,3 +43,101 @@ DROP TABLE t2; DROP USER mysqltest_dfn@localhost; DROP USER mysqltest_inv@localhost; DROP DATABASE mysqltest_db1; +USE test; +# +# Bug#45235: 5.1 does not support 5.0-only syntax triggers in any way +# +DROP TABLE IF EXISTS t1, t2, t3; +CREATE TABLE t1 ( a INT ); +CREATE TABLE t2 ( a INT ); +CREATE TABLE t3 ( a INT ); +INSERT INTO t1 VALUES (1), (2), (3); +INSERT INTO t2 VALUES (1), (2), (3); +INSERT INTO t3 VALUES (1), (2), (3); +# We simulate importing a trigger from 5.0 by writing a .TRN file for +# each trigger plus a .TRG file the way MySQL 5.0 would have done it, +# with syntax allowed in 5.0 only. +# +# Note that in 5.0 the following lines are missing from t1.TRG: +# +# client_cs_names='latin1' +# connection_cl_names='latin1_swedish_ci' +# db_cl_names='latin1_swedish_ci' +# We will get parse errors for most DDL and DML statements when the table +# has broken triggers.

If adjust=TRUE, adjust the cursor position after compressing the page. btr_lift_page_up(): Return a pointer to the father page. BTR_KEEP_POS_FLAG: A new flag for btr_cur_pessimistic_update(). btr_cur_pessimistic_update(): If *big_rec != NULL and flags & BTR_KEEP_POS_FLAG, keep the cursor positioned on the updated record. Also, do not release the index tree x-lock if *big_rec != NULL. btr_cur_mtr_commit_and_start(): Commits and restarts a mini-transaction so that it will retain an x-lock on index->lock and the page of the cursor. This is invoked when btr_cur_pessimistic_update() returns *big_rec != NULL. In all callers of btr_cur_pessimistic_update() that do not pass BTR_KEEP_POS_FLAG, assert that *big_rec == NULL. btr_cur_compress(): Unused function [in the built-in MySQL 5.1], remove. page_rec_get_nth(): Return the nth record on the page (an inverse function of page_rec_get_n_recs_before()). Refactored from page_get_middle_rec(). page_get_middle_rec(): Invoke page_rec_get_nth(). page_cur_insert_rec_zip_reorg(): Make use of the page directory shortcuts in page_rec_get_nth() instead of scanning the whole list of records. row_ins_clust_index_entry_by_modify(): Pass BTR_KEEP_POS_FLAG to btr_cur_pessimistic_update(). row_ins_index_entry_low(): If row_ins_clust_index_entry_by_modify() returns a big_rec, invoke btr_cur_mtr_commit_and_start() in order to commit and start the mini-transaction without releasing the x-locks on index->lock and the cursor page, and write the big_rec. Releasing the page latch in mtr_commit() caused a race condition. row_upd_clust_rec(): Pass BTR_KEEP_POS_FLAG to btr_cur_pessimistic_update(). If it returns a big_rec, invoke btr_cur_mtr_commit_and_start() in order to commit and start the mini-transaction without releasing the x-locks on index->lock and the cursor page, and write the big_rec. Releasing the page latch in mtr_commit() caused a race condition. sync_thread_add_level(): Add the parameter ibool relock. When TRUE, bypass the latching order rules. rw_lock_add_debug_info(): For nested X-lock requests, pass relock=TRUE to sync_thread_add_level(). rb:678 approved by Jimmy Yang --- storage/innobase/btr/btr0btr.c | 40 ++++++++--- storage/innobase/btr/btr0cur.c | 106 ++++++++++++++++++++--------- storage/innobase/include/btr0btr.h | 12 ++-- storage/innobase/include/btr0cur.h | 39 ++++++----- storage/innobase/include/buf0buf.h | 19 ++++++ storage/innobase/include/buf0buf.ic | 2 +- storage/innobase/include/page0page.h | 20 ++++-- storage/innobase/include/page0page.ic | 16 +++++ storage/innobase/include/sync0sync.h | 3 +- storage/innobase/page/page0page.c | 31 ++++----- storage/innobase/row/row0ins.c | 44 ++++++++++-- storage/innobase/row/row0umod.c | 2 + storage/innobase/row/row0upd.c | 34 ++++++--- storage/innobase/sync/sync0rw.c | 4 +- storage/innobase/sync/sync0sync.c | 10 ++- storage/innodb_plugin/ChangeLog | 10 +++ storage/innodb_plugin/btr/btr0btr.c | 52 ++++++++++---- storage/innodb_plugin/btr/btr0cur.c | 80 +++++++++++++++++++--- storage/innodb_plugin/include/btr0btr.h | 15 ++-- storage/innodb_plugin/include/btr0cur.h | 26 +++++-- storage/innodb_plugin/include/btr0cur.ic | 4 +- storage/innodb_plugin/include/buf0buf.h | 27 +++++++- storage/innodb_plugin/include/buf0buf.ic | 17 +---- storage/innodb_plugin/include/page0cur.ic | 5 +- storage/innodb_plugin/include/page0page.h | 39 +++++++++-- storage/innodb_plugin/include/page0page.ic | 32 ++++++++- storage/innodb_plugin/include/sync0rw.ic | 10 +-- storage/innodb_plugin/include/sync0sync.h | 6 +- storage/innodb_plugin/page/page0cur.c | 17 +++-- storage/innodb_plugin/page/page0page.c | 52 +++++++------- storage/innodb_plugin/row/row0ins.c | 48 +++++++++++-- storage/innodb_plugin/row/row0upd.c | 35 +++++++--- storage/innodb_plugin/sync/sync0rw.c | 4 +- storage/innodb_plugin/sync/sync0sync.c | 12 +++- 34 files changed, 650 insertions(+), 223 deletions(-) diff --git a/storage/innobase/btr/btr0btr.c b/storage/innobase/btr/btr0btr.c index 9438277050d..41e0bf6e067 100644 --- a/storage/innobase/btr/btr0btr.c +++ b/storage/innobase/btr/btr0btr.c @@ -1937,7 +1937,7 @@ btr_node_ptr_delete( ut_a(err == DB_SUCCESS);

In btr_cur_optimistic_update() we do this: page_cur_delete_rec(page_cursor, index, offsets, mtr); ... rec = btr_cur_insert_if_possible(cursor, new_entry, 0/*n_ext*/, mtr); ut_a(rec); /* <- We calculated above the insert would fit */ The problem is that page_cur_delete_rec() could fill the modification log while doing page_zip_clear_rec(), requiring recompression for the btr_cur_insert_if_possible(). In a pathological case, the data could fail to recompress. page_zip_clear_rec(): Leave the page modification log alone.

ALTER TABLE MODIFY/CHANGE ... FIRST did nothing except renaming columns if new version of the table had exactly the same structure as the old one (i.e. as result of such statement, names of columns changed their order as specified but data in columns didn't). The same thing happened for ALTER TABLE DROP COLUMN/ADD COLUMN statements which were supposed to produce new version of table with exactly the same structure as the old version of table. I.e. in the latter case the result was the same as if old column was renamed instead of being dropped and new column with default as value being created. Both these problems were caused by the fact that ALTER TABLE implementation incorrectly interpreted both these situations as simple renaming of columns and assumed that in-place ALTER TABLE algorithm could have been used for them. This patch fixes this problem by ensuring that in cases when some column is moved to the first position or some column is dropped the default ALTER TABLE algorithm involving table copying is always used. This is achieved by detecting such situations in mysql_prepare_alter_table() and setting Alter_info::change_level to ALTER_TABLE_DATA_CHANGED for them. mysql-test/r/alter_table.result: Added test for bug #12652385 - "61493: REORDERING COLUMNS TO POSITION FIRST CAN CAUSE DATA TO BE CORRUPTED". mysql-test/t/alter_table.test: Added test for bug #12652385 - "61493: REORDERING COLUMNS TO POSITION FIRST CAN CAUSE DATA TO BE CORRUPTED". sql/sql_table.cc: Changed mysql_prepare_alter_table() to detect situations in which we some column moved to the first position or some column is dropped and ensure that such ALTER TABLE statements won't be carried out using in-place algorithm. The latter could have happened before this patch if new version of table had the same structure as the old one (except the column names). --- mysql-test/r/alter_table.result | 29 +++++++++++++++++++++++++++++ mysql-test/t/alter_table.test | 27 +++++++++++++++++++++++++++ sql/sql_table.cc | 17 +++++++++++++++++ 3 files changed, 73 insertions(+) diff --git a/mysql-test/r/alter_table.result b/mysql-test/r/alter_table.result index 004e2031fb1..674238b14cd 100644 --- a/mysql-test/r/alter_table.result +++ b/mysql-test/r/alter_table.result @@ -1345,4 +1345,33 @@ DROP TABLE t1;

One such workload where it hurts badly is DROP TABLE. This patch removes buf_page_t allocations from buf_buddy and uses ut_malloc instead.

There was a race condition between loading a stored routine (function/procedure/trigger) specified by fully qualified name SCHEMA_NAME.PROC_NAME and dropping the stored routine database. The problem was that there is a window for race condition when one server thread tries to load a stored routine being executed and the other thread tries to drop the stored routine schema. This condition race window exists in implementation of function mysql_change_db() called by db_load_routine() during loading of stored routine to cache. Function mysql_change_db() calls check_db_dir_existence() that might failed because specified database was dropped during concurrent execution of DROP SCHEMA statement. db_load_routine() calls mysql_change_db() with flag 'force_switch' set to 'true' value so when referenced db is not found then my_error() is not called and function mysql_change_db() returns ok. This shadows information about schema opening error in db_load_routine(). Then db_load_routine() makes attempt to parse stored routine that is failed. This makes to return error to sp_cache_routines_and_add_tables_aux() but since during error generation a call to my_error wasn't made and hence THD::main_da wasn't set we set the generic "mysql.proc table corrupt" error when running sp_cache_routines_and_add_tables_aux(). The fix is to install an error handler inside db_load_routine() for the mysql_op_change_db() call, and check later if the ER_BAD_DB_ERROR was caught. sql/sql_db.cc: Added synchronization point "before_db_dir_check" to emulate a race condition during processing of CALL/DROP SCHEMA. --- mysql-test/r/sp_sync.result | 14 +++++++++++++- mysql-test/t/sp_sync.test | 31 ++++++++++++++++++++++++++++++- sql/sp.cc | 42 +++++++++++++++++++++++++++++++++++++++++- sql/sql_db.cc | 3 +++ 4 files changed, 87 insertions(+), 3 deletions(-) diff --git a/mysql-test/r/sp_sync.result b/mysql-test/r/sp_sync.result index afa37e70531..17292f4c1a8 100644 --- a/mysql-test/r/sp_sync.result +++ b/mysql-test/r/sp_sync.result @@ -1,4 +1,4 @@ -Tests of syncronization of stored procedure execution. +Tests of synchronization of stored procedure execution. # # Bug#48157: crash in Item_field::used_tables # @@ -20,4 +20,16 @@ SET DEBUG_SYNC = 'now SIGNAL go'; # code, this test statement will hang.

But that fix has a remaining bug. It added this assert; ut_ad(ind_field->prefix_len); before a section of code that assumes there is a prefix_len. The patch replaced code that explicitly avoided this with a check for prefix_len. It turns out that the purge thread can get to that assert without a prefix_len because it does not use a row_ext_t* . When UNIV_DEBUG is not defined, the affect of this is that the purge thread sets the dfield->len to zero and then cannot find the entry in the index to purge. So secondary index entries remain unpurged. This patch does not do the assert. Instead, it uses 'if (ind_field->prefix_len) {...}' around the section of code that assumes a prefix_len. This is the way the patch I provided to Marko did it. The test case is simply modified to do a sleep(10) in order to give the purge thread a chance to run. Without the code change to row0row.c, this modified testcase will assert if InnoDB was compiled with UNIV_DEBUG. I tried to sleep(5), but it did not always assert. --- .../suite/innodb_plugin/r/innodb-index.result | 1 + mysql-test/suite/innodb_plugin/t/innodb-index.test | 3 +++ storage/innodb_plugin/row/row0row.c | 21 +++++++++++++-------- 3 files changed, 17 insertions(+), 8 deletions(-) diff --git a/mysql-test/suite/innodb_plugin/r/innodb-index.result b/mysql-test/suite/innodb_plugin/r/innodb-index.result index 32a029bc4ca..b24f282dfc4 100644 --- a/mysql-test/suite/innodb_plugin/r/innodb-index.result +++ b/mysql-test/suite/innodb_plugin/r/innodb-index.result @@ -1022,6 +1022,7 @@ v16 VARCHAR(500), v17 VARCHAR(500), v18 VARCHAR(500) CREATE INDEX idx1 ON t1(a,v1); INSERT INTO t1 VALUES(9,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r); UPDATE t1 SET a=1000; +DELETE FROM t1; DROP TABLE t1; set global innodb_file_per_table=0; set global innodb_file_format=Antelope; diff --git a/mysql-test/suite/innodb_plugin/t/innodb-index.test b/mysql-test/suite/innodb_plugin/t/innodb-index.test index 28393553ec2..52f94990b15 100644 --- a/mysql-test/suite/innodb_plugin/t/innodb-index.test +++ b/mysql-test/suite/innodb_plugin/t/innodb-index.test @@ -475,6 +475,9 @@ CREATE TABLE t1(a INT, CREATE INDEX idx1 ON t1(a,v1); INSERT INTO t1 VALUES(9,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r,@r); UPDATE t1 SET a=1000; +DELETE FROM t1; +# Let the purge thread clean up this file. +-- sleep 10 DROP TABLE t1; eval set global innodb_file_per_table=$per_table; diff --git a/storage/innodb_plugin/row/row0row.c b/storage/innodb_plugin/row/row0row.c index 69753d15737..9cdbbe76e04 100644 --- a/storage/innodb_plugin/row/row0row.c +++ b/storage/innodb_plugin/row/row0row.c @@ -148,22 +148,27 @@ row_build_index_entry( continue; } } else if (dfield_is_ext(dfield)) { - /* This table should be in Antelope format - (ROW_FORMAT=REDUNDANT or ROW_FORMAT=COMPACT). - In that format, the maximum column prefix + /* This table is either in Antelope format + (ROW_FORMAT=REDUNDANT or ROW_FORMAT=COMPACT) + or a purge record where the ordered part of + the field is not external. + In Antelope, the maximum column prefix index length is 767 bytes, and the clustered index record contains a 768-byte prefix of each off-page column. */ ut_a(len >= BTR_EXTERN_FIELD_REF_SIZE); len -= BTR_EXTERN_FIELD_REF_SIZE; + dfield_set_len(dfield, len); } /* If a column prefix index, take only the prefix. */ - ut_ad(ind_field->prefix_len); - len = dtype_get_at_most_n_mbchars( - col->prtype, col->mbminlen, col->mbmaxlen, - ind_field->prefix_len, len, dfield_get_data(dfield)); - dfield_set_len(dfield, len); + if (ind_field->prefix_len) { + len = dtype_get_at_most_n_mbchars( + col->prtype, col->mbminlen, col->mbmaxlen, + ind_field->prefix_len, len, + dfield_get_data(dfield)); + dfield_set_len(dfield, len); + } } ut_ad(dtuple_check_typed(entry)); -- cgit v1.2.1 From ffcd04c2e8ef68a0c888a2d9545df9933529e90e Mon Sep 17 00:00:00 2001 From: Joerg Bruehe Date: Fri, 8 Jul 2011 16:25:32 +0200 Subject: Fix Bug #47337: innochecksum not built for --with-plugin-innodb_plugin --without-plugin-innobase In 5.1, we can have the traditional "innobase" code (built-in) or the new version "innodb" (plugin). The help tool "innochecksum" is useful for both, but its generation was coupled to "innobase" only. Fix this by treating both "innobase" and "innodb" equivalent in the configure phase, this affects both "innochecksum" and the InnoDB documentation.

HA_ERR was returning 0 (null string) when no error happened (error=0). Since HA_ERR is used in DBUG_PRINT, regardless there was an error or not, the server could crash in solaris debug builds. We fix this by: - deploying an assertion that ensures that the function is not called when no error has happened; - making sure that HA_ERR is only called when an error happened; - making HA_ERR return "No Error", instead of 0, for non-debug builds if it is called when no error happened. This will make HA_ERR return values to work with DBUG_PRINT on solaris debug builds. --- sql/log_event.cc | 15 +++++++++++---- 1 file changed, 11 insertions(+), 4 deletions(-) diff --git a/sql/log_event.cc b/sql/log_event.cc index 82a6d9e8ffc..fac3e3f264b 100644 --- a/sql/log_event.cc +++ b/sql/log_event.cc @@ -59,6 +59,11 @@ static int rows_event_stmt_cleanup(Relay_log_info const *rli, THD* thd); static const char *HA_ERR(int i) { + /* + This function should only be called in case of an error + was detected + */ + DBUG_ASSERT(i != 0); switch (i) { case HA_ERR_KEY_NOT_FOUND: return "HA_ERR_KEY_NOT_FOUND"; case HA_ERR_FOUND_DUPP_KEY: return "HA_ERR_FOUND_DUPP_KEY"; @@ -111,7 +116,7 @@ static const char *HA_ERR(int i) case HA_ERR_CORRUPT_EVENT: return "HA_ERR_CORRUPT_EVENT"; case HA_ERR_ROWS_EVENT_APPLY : return "HA_ERR_ROWS_EVENT_APPLY"; } - return 0; + return "No Error!"; } /** @@ -132,7 +137,7 @@ static void inline slave_rows_error_report(enum loglevel level, int ha_error, TABLE *table, const char * type, const char *log_name, ulong pos) { - const char *handler_error= HA_ERR(ha_error); + const char *handler_error= (ha_error ?

Because of this, the patch was not backported to the built-in InnoDB in MySQL 5.1. Furthermore, there is no test case for InnoDB Plugin in MySQL 5.1, because the delete buffering in MySQL 5.5 makes triggering the failure much easier. When a freed page for which there exist orphaned buffered changes is allocated and reused for something else, buf_page_create() will discard the buffered changes by invoking ibuf_merge_or_delete_for_page(). This would violate the InnoDB latching order. Tweak the latching order as follows. Move SYNC_IBUF_MUTEX below SYNC_FSP_PAGE, where it logically belongs, and assign new latching levels for the ibuf->index->lock and the insert buffer B-tree pages: #define SYNC_IBUF_MUTEX 370 /* ibuf_mutex */ #define SYNC_IBUF_INDEX_TREE 360 #define SYNC_IBUF_TREE_NODE_NEW 359 #define SYNC_IBUF_TREE_NODE 358 btr_block_get(), btr_page_get(): In UNIV_SYNC_DEBUG, add the parameter "index" for determining the appropriate latching order (SYNC_IBUF_TREE_NODE or SYNC_TREE_NODE). btr_page_alloc_for_ibuf(), btr_create(): Use SYNC_IBUF_TREE_NODE_NEW instead of SYNC_TREE_NODE_NEW for insert buffer pages. btr_cur_search_to_nth_level(), btr_pcur_restore_position_func(): Use SYNC_IBUF_TREE_NODE instead of SYNC_TREE_NODE for insert buffer pages. btr_search_guess_on_hash(): Assert that the index is not an insert buffer tree. dict_index_add_to_cache(): Use SYNC_IBUF_INDEX_TREE for the insert buffer tree (ibuf->index->lock). ibuf0ibuf.c: Use SYNC_IBUF_TREE_NODE or SYNC_IBUF_TREE_NODE_NEW for all B-tree pages. ibuf_merge_or_delete_for_page(): Assert that the user page is BUF_IO_READ fixed. Only in this way it is OK to latch it as SYNC_IBUF_TREE_NODE instead of the proper SYNC_TREE_NODE (which would violate the changed latching order). sync_thread_add_level(): Remove the special tweak for SYNC_IBUF_MUTEX. Add rules for the added latching levels. rb:591 approved by Jimmy Yang --- storage/innodb_plugin/ChangeLog | 9 +++ storage/innodb_plugin/btr/btr0btr.c | 100 +++++++++++++++++++----------- storage/innodb_plugin/btr/btr0cur.c | 36 ++++++----- storage/innodb_plugin/btr/btr0pcur.c | 11 ++-- storage/innodb_plugin/btr/btr0sea.c | 3 +- storage/innodb_plugin/dict/dict0crea.c | 4 +- storage/innodb_plugin/dict/dict0dict.c | 6 +- storage/innodb_plugin/ibuf/ibuf0ibuf.c | 24 ++++--- storage/innodb_plugin/include/btr0btr.h | 32 +++++++--- storage/innodb_plugin/include/btr0btr.ic | 10 ++- storage/innodb_plugin/include/sync0sync.h | 9 ++- storage/innodb_plugin/sync/sync0sync.c | 29 +++++---- 12 files changed, 179 insertions(+), 94 deletions(-) diff --git a/storage/innodb_plugin/ChangeLog b/storage/innodb_plugin/ChangeLog index f873f3a24bd..0b90b5729d5 100644 --- a/storage/innodb_plugin/ChangeLog +++ b/storage/innodb_plugin/ChangeLog @@ -1,3 +1,12 @@ +2011-08-15 The InnoDB Team + + * btr/btr0btr.c, btr/btr0cur.c, btr/btr0pcur.c, btr/btr0sea.c, + dict/dict0crea.c, dict/dict0dict.c, ibuf/ibuf0ibuf.c, + include/btr0btr.h, include/btr0btr.ic, include/sync0sync.h, + sync/sync0sync.c: + Fix Bug#11766591 59733: Possible deadlock when buffered changes + are to be discarded in buf_page_create() + 2011-08-08 The InnoDB Team * row/row0sel.c: diff --git a/storage/innodb_plugin/btr/btr0btr.c b/storage/innodb_plugin/btr/btr0btr.c index ac188c8c2fd..5e6724bbd54 100644 --- a/storage/innodb_plugin/btr/btr0btr.c +++ b/storage/innodb_plugin/btr/btr0btr.c @@ -690,7 +690,8 @@ btr_root_block_get( zip_size = dict_table_zip_size(index->table);

Particularly, this might have happened when another connection killed this FLUSH TABLE statement/connection. Also this problem might have occurred when we failed to reopen MERGE table or one of its children when executing DDL statement under LOCK TABLES. The problem was caused by the fact that reopen_tables() might have failed to reopen child table but still tried to reopen, reattach children for and re-lock its parent. Vice versa it might have failed to reopen parent but kept references from children to parent around. Since reopen_tables() closes table it has failed to reopen and therefore frees all associated memory such dangling references led to crashes when followed. This patch solves this problem by ensuring that we always close parent table and all its children if we fail to reopen this table or one of its children. Same happens if we fail to reattach children to parent. Affects 5.1 only. mysql-test/r/merge.result: A test case for BUG#11763712. mysql-test/t/merge.test: A test case for BUG#11763712. sql/sql_base.cc: When flushing tables under LOCK TABLES, all locked and flushed tables are released and then reopened. It may happen that we failed to reopen some tables, in this case we reopen as much tables as possible. If it was not possible to reopen MERGE child, MERGE parent is unusable and must be removed from thread open tables list. If it was not possible to reopen MERGE parent, all MERGE child table objects are unusable as well, at least because their locks are handled by MERGE parent. They must also be removed from thread open tables list. In other words if it was impossible to reopen any object of a MERGE table or reattach child tables, all objects of this MERGE table must be considered unusable and closed. --- mysql-test/r/merge.result | 29 ++++++++ mysql-test/t/merge.test | 45 ++++++++++++ sql/sql_base.cc | 183 +++++++++++++++++++++++++++++++++++----------- 3 files changed, 215 insertions(+), 42 deletions(-) diff --git a/mysql-test/r/merge.result b/mysql-test/r/merge.result index 3af152672ab..a4f1c79dff4 100644 --- a/mysql-test/r/merge.result +++ b/mysql-test/r/merge.result @@ -2341,4 +2341,33 @@ REPAIR TABLE m1;

When a record that contains off-page columns (BLOBs) is updated, we must first write redo log about the BLOB page writes, and only after that write the redo log about the B-tree changes. The buggy fix would log the B-tree changes first, meaning that after recovery, we could end up having a record that contains a null BLOB pointer. Because we will be redo logging the writes off the off-page columns before the B-tree changes, we must make sure that the pages chosen for the off-page columns are free both before and after the B-tree changes. In this way, the worst thing that can happen in crash recovery is that the BLOBs are written to free pages, but the B-tree changes are not applied. The BLOB pages would correctly remain free in this case. To achieve this, we must allocate the BLOB pages in the mini-transaction of the B-tree operation. A further quirk is that BLOB pages are allocated from the same file segment as leaf pages. Because of this, we must temporarily "hide" any leaf pages that were freed during the B-tree operation by "fake allocating" them prior to writing the BLOBs, and freeing them again before the mtr_commit() of the B-tree operation, in btr_mark_freed_leaves(). btr_cur_mtr_commit_and_start(): Remove this faulty function that was introduced in the Bug#12612184 fix. The problem that this function was trying to address was that when we did mtr_commit() the BLOB writes before the mtr_commit() of the update, the new BLOB pages could have overwritten clustered index B-tree leaf pages that were freed during the update. If recovery applied the redo log of the BLOB writes but did not see the log of the record update, the index tree would be corrupted. The correct solution is to make the freed clustered index pages unavailable to the BLOB allocation. This function is also a likely culprit of InnoDB hangs that were observed when testing the Bug#12612184 fix. btr_mark_freed_leaves(): Mark all freed clustered index leaf pages of a mini-transaction allocated (nonfree=TRUE) before storing the BLOBs, or freed (nonfree=FALSE) before committing the mini-transaction. btr_freed_leaves_validate(): A debug function for checking that all clustered index leaf pages that have been marked free in the mini-transaction are consistent (have not been zeroed out). btr_page_alloc_low(): Refactored from btr_page_alloc(). Return the number of the allocated page, or FIL_NULL if out of space. Add the parameter "mtr_t* init_mtr" for specifying the mini-transaction where the page should be initialized, or if this is a "fake allocation" (init_mtr=NULL) by btr_mark_freed_leaves(nonfree=TRUE). btr_page_alloc(): Add the parameter init_mtr, allowing the page to be initialized and X-latched in a different mini-transaction than the one that is used for the allocation. Invoke btr_page_alloc_low(). If a clustered index leaf page was previously freed in mtr, remove it from the memo of previously freed pages. btr_page_free(): Assert that the page is a B-tree page and it has been X-latched by the mini-transaction. If the freed page was a leaf page of a clustered index, link it by a MTR_MEMO_FREE_CLUST_LEAF marker to the mini-transaction. btr_store_big_rec_extern_fields_func(): Add the parameter alloc_mtr, which is NULL (old behaviour in inserts) and the same as local_mtr in updates. If alloc_mtr!=NULL, the BLOB pages will be allocated from it instead of the mini-transaction that is used for writing the BLOBs. fsp_alloc_from_free_frag(): Refactored from fsp_alloc_free_page(). Allocate the specified page from a partially free extent. fseg_alloc_free_page_low(), fseg_alloc_free_page_general(): Add the parameter "mtr_t* init_mtr" for specifying the mini-transaction where the page should be initialized, or NULL if this is a "fake allocation" that prevents the reuse of a previously freed B-tree page for BLOB storage. If init_mtr==NULL, try harder to reallocate the specified page and assert that it succeeded. fsp_alloc_free_page(): Add the parameter "mtr_t* init_mtr" for specifying the mini-transaction where the page should be initialized. Do not allow init_mtr == NULL, because this function is never to be used for "fake allocations". mtr_t: Add the operation MTR_MEMO_FREE_CLUST_LEAF and the flag mtr->freed_clust_leaf for quickly determining if any MTR_MEMO_FREE_CLUST_LEAF operations have been posted. row_ins_index_entry_low(): When columns are being made off-page in insert-by-update, invoke btr_mark_freed_leaves(nonfree=TRUE) and pass the mini-transaction as the alloc_mtr to btr_store_big_rec_extern_fields(). Finally, invoke btr_mark_freed_leaves(nonfree=FALSE) to avoid leaking pages. row_build(): Correct a comment, and add a debug assertion that a record that contains NULL BLOB pointers must be a fresh insert. row_upd_clust_rec(): When columns are being moved off-page, invoke btr_mark_freed_leaves(nonfree=TRUE) and pass the mini-transaction as the alloc_mtr to btr_store_big_rec_extern_fields(). Finally, invoke btr_mark_freed_leaves(nonfree=FALSE) to avoid leaking pages. buf_reset_check_index_page_at_flush(): Remove. The function fsp_init_file_page_low() already sets bpage->check_index_page_at_flush=FALSE. There is a known issue in tablespace extension. If the request to allocate a BLOB page leads to the tablespace being extended, crash recovery could see BLOB writes to pages that are off the tablespace file bounds. This should trigger an assertion failure in fil_io() at crash recovery. The safe thing would be to write redo log about the tablespace extension to the mini-transaction of the BLOB write, not to the mini-transaction of the record update.
