Before this patch, the parser would execute: - Select->expr_list.push_front() - Select->expr_list.pop() when parsing expressions lists, in the following rules: - udf_expr_list - expr_list - ident_list This is unnecessary, and introduces overhead due to the memory allocations performed with Select->expr_list With this patch, this code has been removed. The list being parsed is maintained in the parser stack instead. Also, 'udf_expr_list' has been renamed 'opt_udf_expr_list', since this production can be empty. sql/sql_lex.cc: Removed unused attribute expr_list sql/sql_lex.h: Removed unused attribute expr_list sql/sql_yacc.yy: Improved performances when parsing expression lists

This is a performance bug, related to the parsing or 'OR' and 'AND' boolean expressions. Let N be the number of expressions involved in a OR (respectively AND). When N=1 For example, "select 1" involve only 1 term: there is no OR operator. In 4.0 and 4.1, parsing expressions not involving OR had no overhead. In 5.0, parsing adds some overhead, with Select->expr_list. With this patch, the overhead introduced in 5.0 has been removed, so that performances for N=1 should be identical to the 4.0 performances, which are optimal (there is no code executed at all) The overhead in 5.0 was in fact affecting significantly some operations. For example, loading 1 Million rows into a table with INSERTs, for a table that has 100 columns, leads to parsing 100 Millions of expressions, which means that the overhead related to Select->expr_list is executed 100 Million times ... Considering that N=1 is by far the most probable expression, this case should be optimal. When N=2 For example, "select a OR b" involves 2 terms in the OR operator. In 4.0 and 4.1, parsing expressions involving 2 terms created 1 Item_cond_or node, which is the expected result. In 5.0, parsing these expression also produced 1 node, but with some extra overhead related to Select->expr_list : creating 1 list in Select->expr_list and another in Item_cond::list is inefficient. With this patch, the overhead introduced in 5.0 has been removed so that performances for N=2 should be identical to the 4.0 performances. Note that the memory allocation uses the new (thd->mem_root) syntax directly. The cost of "is_cond_or" is estimated to be neglectable: the real problem of the performance degradation comes from unneeded memory allocations. When N>=3 For example, "select a OR b OR c ...", which involves 3 or more terms. In 4.0 and 4.1, the parser had no significant cost overhead, but produced an Item tree which is difficult to evaluate / optimize during runtime. In 5.0, the parser produces a better Item tree, using the Item_cond constructor that accepts a list of children directly, but at an extra cost related to Select->expr_list. With this patch, the code is implemented to take the best of the two implementations: - there is no overhead with Select->expr_list - the Item tree generated is optimized and flattened. This is achieved by adding children nodes into the Item tree directly, with Item_cond::add(), which avoids the need for temporary lists and memory allocation Note that this patch also provide an extra optimization, that the previous code in 5.0 did not provide: expressions are flattened in the Item tree, based on what the expression already parsed is, and not based on the order in which rules are reduced. For example : "(a OR b) OR c", "a OR (b OR c)" would both be represented with 2 Item_cond_or nodes before this patch, and with 1 node only with this patch. The logic used is based on the mathematical properties of the OR operator (it's associative), and produces a simpler tree. sql/item_cmpfunc.h: Improved performances for parsing boolean expressions sql/sql_yacc.yy: Improved performances for parsing boolean expressions mysql-test/r/parser_precedence.result: Added test cases to cover boolean operator precedence mysql-test/t/parser_precedence.test: Added test cases to cover boolean operator precedence

SP with local variables with non-ASCII names crashed the server. The server replaces SP local variable names with NAME_CONST calls when putting statements into the binary log. It used UTF8-encoded item names as variable names for the replacement inside NAME_CONST calls. However, statement string may be encoded by any known character set by the SET NAMES statement. The server used byte length of UTF8-encoded names to increment the position in the query string that led to array index overrun. sql/item.cc: Fixed bug #30120. The Item_splocal class constructor has been modified to accept new parameter `len_in_q': the byte length of variable name in the query string. sql/item.h: Fixed bug #30120. The Item_splocal class has been modified to keep new field `len_in_query': the byte length of variable name in the query string. sql/sp_head.cc: Fixed bug #30120. The subst_spvars function has been modified to increment position in the query string by the lengths of not encoded variable names instead of byte length of names encoded to UTF-8. sql/sql_yacc.yy: Fixed bug #30120. The simple_ident rule action has been modified to pass the byte length of the local variable name token to the Item_splocal object constructor. mysql-test/t/sp.test: Updated test case for bug #30120. mysql-test/r/sp.result: Updated test case for bug #30120.

causes full table lock on innodb table. Also fixes Bug#28502 Triggers that update another innodb table will block on X lock unnecessarily (duplciate). Code review fixes. Both bugs' synopses are misleading: InnoDB table is not X locked. The statements, however, cannot proceed concurrently, but this happens due to lock conflicts for tables used in triggers, not for the InnoDB table. If a user had an InnoDB table, and two triggers, AFTER UPDATE and AFTER INSERT, competing for different resources (e.g. two distinct MyISAM tables), then these two triggers would not be able to execute concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would not be able to run concurrently. The problem had other side-effects (see respective bug reports). This behavior was a consequence of a shortcoming of the pre-locking algorithm, which would not distinguish between different DML operations (e.g. INSERT and DELETE) and pre-lock all the tables that are used by any trigger defined on the subject table. The idea of the fix is to extend the pre-locking algorithm to keep track, for each table, what DML operation it is used for and not load triggers that are known to never be fired. mysql-test/r/trigger-trans.result: Update results (Bug#26141) mysql-test/r/trigger.result: Update results (Bug#28502) mysql-test/t/trigger-trans.test: Add a test case for Bug#26141 mixing table types in trigger causes full table lock on innodb table. mysql-test/t/trigger.test: Add a test case for Bug#28502 Triggers that update another innodb table will block echo on X lock unnecessarily. Add more test coverage for triggers. sql/item.h: enum trg_event_type is needed in table.h sql/sp.cc: Take into account table_list->trg_event_map when determining what tables to pre-lock. After this change, if we attempt to fire a trigger for which we had not pre-locked any tables, error 'Table was not locked with LOCK TABLES' will be printed. This, however, should never happen, provided the pre-locking algorithm has no programming bugs. Previously a trigger key in the sroutines hash was based on the name of the table the trigger belongs to. This was possible because we would always add to the pre-locking list all the triggers defined for a table when handling this table. Now the key is based on the name of the trigger, owing to the fact that a trigger name must be unique in the database it belongs to. sql/sp_head.cc: Generate sroutines hash key in init_spname(). This is a convenient place since there we have all the necessary information and can avoid an extra alloc. Maintain and merge trg_event_map when adding and merging elements of the pre-locking list. sql/sp_head.h: Add ,m_sroutines_key member, used when inserting the sphead for a trigger into the cache of routines used by a statement. Previously the key was based on the table name the trigger belonged to, since for a given table we would add to the sroutines list all the triggers defined on it. sql/sql_lex.cc: Introduce a new lex step: set_trg_event_type_for_tables(). It is called when we have finished parsing but before opening and locking tables. Now this step is used to evaluate for each TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any, it is used in. In future this method could be extended to aggregate other information that is hard to aggregate during parsing. sql/sql_lex.h: Add declaration for set_trg_event_type_for_tables(). sql/sql_parse.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs. sql/sql_prepare.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.h: Remove an obsolete member. sql/sql_view.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_yacc.yy: Move assignment of sp_head::m_type before calling sp_head::init_spname(), one is now used inside another. sql/table.cc: Implement TABLE_LIST::set_trg_event_map() - a method that calculates wh triggers may be fired on this table when executing a statement. sql/table.h: Add missing declarations. Move declaration of trg_event_type from item.h (it will be needed for trg_event_map bitmap when we start using Bitmap template instead of uint8).

fails if a database is not selected prior. The problem manifested itself when a user tried to create a routine that had non-fully-qualified identifiers in its bodies and there was no current database selected. This is a regression introduced by the fix for Bug 19022: The patch for Bug 19022 changes the code to always produce a warning if we can't resolve the current database in the parser. In this case this was not necessary, since even though the produced parsed tree was incorrect, we never re-use sphead that was obtained at first parsing of CREATE PROCEDURE. The sphead that is anyhow used is always obtained through db_load_routine, and there we change the current database to sphead->m_db before calling yyparse. The idea of the fix is to resolve the current database directly using lex->sphead->m_db member when parsing a stored routine body, when such is present. This patch removes the need to reset the current database when loading a trigger or routine definition into SP cache. The redundant code will be removed in 5.1. mysql-test/r/sp.result: Update test results (Bug#29050) mysql-test/r/trigger.result: Update results. mysql-test/t/sp.test: Add a test case for Bug#29050 mysql-test/t/trigger.test: Fix wrong behavior covered with tests. sql/sql_lex.cc: Implement st_lex::copy_db_to(). sql/sql_lex.h: Declare st_lex::copy_db_to(). sql/sql_parse.cc: Use st_lex::copy_db_to() in add_table_to_list, rather than THD::copy_db_to(). The former will use the database of the sphead, if we're parsing a stored routine, not the default database in THD. The default database is needed to initialize tables->db when the database part was not explicitly specified in the identifier. sql/sql_yacc.yy: Use st_lex::copy_db_to() in the parser, rather than THD::copy_db_to(). The former will use the database of the sphead, if we're parsing a stored routine, not the default database in THD.

- BUG#11986: Stored routines and triggers can fail if the code has a non-ascii symbol - BUG#16291: mysqldump corrupts string-constants with non-ascii-chars - BUG#19443: INFORMATION_SCHEMA does not support charsets properly - BUG#21249: Character set of SP-var can be ignored - BUG#25212: Character set of string constant is ignored (stored routines) - BUG#25221: Character set of string constant is ignored (triggers) There were a few general problems that caused these bugs: 1. Character set information of the original (definition) query for views, triggers, stored routines and events was lost. 2. mysqldump output query in client character set, which can be inappropriate to encode definition-query. 3. INFORMATION_SCHEMA used strings with mixed encodings to display object definition; 1. No query-definition-character set. In order to compile query into execution code, some extra data (such as environment variables or the database character set) is used. The problem here was that this context was not preserved. So, on the next load it can differ from the original one, thus the result will be different. The context contains the following data: - client character set; - connection collation (character set and collation); - collation of the owner database; The fix is to store this context and use it each time we parse (compile) and execute the object (stored routine, trigger, ...). 2. Wrong mysqldump-output. The original query can contain several encodings (by means of character set introducers). The problem here was that we tried to convert original query to the mysqldump-client character set. Moreover, we stored queries in different character sets for different objects (views, for one, used UTF8, triggers used original character set). The solution is - to store definition queries in the original character set; - to change SHOW CREATE statement to output definition query in the binary character set (i.e. without any conversion); - introduce SHOW CREATE TRIGGER statement; - to dump special statements to switch the context to the original one before dumping and restore it afterwards. Note, in order to preserve the database collation at the creation time, additional ALTER DATABASE might be used (to temporary switch the database collation back to the original value). In this case, ALTER DATABASE privilege will be required. This is a backward-incompatible change. 3. INFORMATION_SCHEMA showed non-UTF8 strings The fix is to generate UTF8-query during the parsing, store it in the object and show it in the INFORMATION_SCHEMA. Basically, the idea is to create a copy of the original query convert it to UTF8. Character set introducers are removed and all text literals are converted to UTF8. This UTF8 query is intended to provide user-readable output. It must not be used to recreate the object. Specialized SHOW CREATE statements should be used for this. The reason for this limitation is the following: the original query can contain symbols from several character sets (by means of character set introducers). Example: - original query: CREATE VIEW v1 AS SELECT _cp1251 'Hello' AS c1; - UTF8 query (for INFORMATION_SCHEMA): CREATE VIEW v1 AS SELECT 'Hello' AS c1; client/mysqldump.c: Set original character set and collation before dumping definition query. include/my_sys.h: Move out-parameter to the end of list. mysql-test/lib/mtr_report.pl: Ignore server-warnings during the test case. mysql-test/r/create.result: Update result file. mysql-test/r/ctype_cp932_binlog_stm.result: Update result file. mysql-test/r/events.result: Update result file. mysql-test/r/events_bugs.result: Update result file. mysql-test/r/events_grant.result: Update result file. mysql-test/r/func_in.result: Update result file. mysql-test/r/gis.result: Update result file. mysql-test/r/grant.result: Update result file. mysql-test/r/information_schema.result: Update result file. mysql-test/r/information_schema_db.result: Update result file. mysql-test/r/lowercase_view.result: Update result file. mysql-test/r/mysqldump.result: Update result file. mysql-test/r/ndb_sp.result: Update result file. mysql-test/r/ps.result: Update result file. mysql-test/r/rpl_replicate_do.result: Update result file. mysql-test/r/rpl_sp.result: Update result file. mysql-test/r/rpl_trigger.result: Update result file. mysql-test/r/rpl_view.result: Update result file. mysql-test/r/show_check.result: Update result file. mysql-test/r/skip_grants.result: Update result file. mysql-test/r/sp-destruct.result: Update result file. mysql-test/r/sp-error.result: Update result file. mysql-test/r/sp-security.result: Update result file. mysql-test/r/sp.result: Update result file. mysql-test/r/sql_mode.result: Update result file. mysql-test/r/system_mysql_db.result: Update result file. mysql-test/r/temp_table.result: Update result file. mysql-test/r/trigger-compat.result: Update result file. mysql-test/r/trigger-grant.result: Update result file. mysql-test/r/trigger.result: Update result file. mysql-test/r/view.result: Update result file. mysql-test/r/view_grant.result: Update result file. mysql-test/t/events.test: Update test case (new columns added). mysql-test/t/information_schema.test: Update test case (new columns added). mysql-test/t/show_check.test: Test case for SHOW CREATE TRIGGER in prepared statements and stored routines. mysql-test/t/sp-destruct.test: Update test case (new columns added). mysql-test/t/sp.test: Update test case (new columns added). mysql-test/t/view.test: Update test. mysys/charset.c: Move out-parameter to the end of list. scripts/mysql_system_tables.sql: Add new columns to mysql.proc and mysql.event. scripts/mysql_system_tables_fix.sql: Add new columns to mysql.proc and mysql.event. sql/event_data_objects.cc: Support new attributes for events. sql/event_data_objects.h: Support new attributes for events. sql/event_db_repository.cc: Support new attributes for events. sql/event_db_repository.h: Support new attributes for events. sql/events.cc: Add new columns to SHOW CREATE event resultset. sql/mysql_priv.h: 1.

ALTER VIEW is currently not supported as a prepared statement and should be disabled as such as they otherwise could cause server crashes. ALTER VIEW is currently not supported when called from stored procedures or functions for related reasons and should also be disabled. This patch disables these DDL statements and adjusts the appropriate test cases accordingly. Additional tests has been added to reflect on the fact that we do support CREATE/ALTER/DROP TABLE for Prepared Statements (PS), Stored Procedures (SP) and PS within SP. mysql-test/r/ps_1general.result: - Updated test to reflect on the new policy to disallow ALTER VIEW within SP. mysql-test/r/sp-dynamic.result: - Added PS ALTER TABLE test from within SP-context to demonstrate that CREATE/ALTER/DROP TABLE statements is working. - Added PS CREATE/ALTER/DROP VIEW tests from within SP-context to show that ALTER VIEW is not supported, CREATE VIEW/DROP VIEW are supported. mysql-test/r/sp-error.result: - Updated test to reflect on the new policy to disallow VIEW DDL within SP. mysql-test/t/ps_1general.test: - Updated test to reflect on the new policy to disallow VIEW DDL within SP. mysql-test/t/sp-dynamic.test: - Add PS ALTER TABLE test from within SP to demonstrate that CREATE/ALTER/DROP TABLE statements are supported. mysql-test/t/sp-error.test: - Updated test to reflect on the new policy to disallow ALTER VIEW within SP-context. - Changed error code 1314 to the more abstract ER_SP_BADSTATEMENT. sql/sql_class.h: - Added comment for clarity sql/sql_parse.cc: - Added comment for clarity sql/sql_prepare.cc: - Disallow ALTER VIEW as prepared statements until they are properly supported.

Fixed runtime to no longer allow the caching of queries with UDF calls. mysql-test/r/udf.result: Added a test that turns on caching and checks that querys calling UDFs don't get cached. mysql-test/t/udf.test: Added a test that turns on caching and checks that querys calling UDFs don't get cached. sql/sql_yacc.yy: Fixed code to set safe_to_cache_query=0 regardless if the function call is a UDF or SP. Where it was placed previously -- at the very end of the else testing for UDFs -- it only executed the statement if the function call was a stored procedure call.

Changed code to enforce that SQL_CACHE only in the first SELECT is used to turn on caching(as documented), but any SQL_NO_CACHE will turn off caching (not documented, but a useful behaviour, especially for machine generated queries). Added test cases to explicitly test the documented caching behaviour and test cases for the reported bug. mysql-test/r/query_cache.result: Added non-bug specific tests that ensure that only SQL_CACHE in the first SELECT is respected when encountered by the parser. These tests validate what is already documented, that only the outer most SELECTS can use the SQL_CACHE option to turn on caching. Because it would break existing SQL applications, we do not return an error if the SQL_CACHE expression is found in nested SELECTs. Also added test to validate nested SELECT can contain SQL_NO_CACHE and it will always turn off caching for the whole query. Also added a bug specific test case to validate that the buggy behavior as reported has been fixed. mysql-test/t/query_cache.test: Added non-bug specific tests that ensure that only SQL_CACHE in the first SELECT is respected when encountered by the parser. These tests validate what is already documented, that only the outer most SELECTS can use the SQL_CACHE option to turn on caching. Because it would break existing SQL applications, we do not return an error if the SQL_CACHE expression is found in nested SELECTs. Also added test to validate nested SELECT can contain SQL_NO_CACHE and it will always turn off caching for the whole query. Also added a bug specific test case to validate that the buggy behavior as reported has been fixed. sql/sql_yacc.yy: Added an explicit check to make sure "SELECT SQL_CACHE" only works on the first select in a query. The parser will always hit the outermost SELECT first, and if the SQL_CACHE option is found it sets the safe_to_query flag in the lex. Then, if there are subseqent "uncachable" subqueries or functions, as it parses those elements it sets the safe_to_query to 0. However, this cause problems if nested SELECTs also used the SQL_CACHE option, because then it would set back safe_to_query to 1, even though there are uncacheable expressions previously parsed. By adding the check to ensure only the first SELECT can turn caching on, it means a subsequent SQL_CACHE option can't turn caching back on after a uncacheable subsequery was already encountered.

Bug 28127 (Some valid identifiers names are not parsed correctly) Bug 26302 (MySQL server cuts off trailing "*/" from comments in SP/func) This patch is the second part of a major cleanup, required to fix Bug 25411 (trigger code truncated). The root cause of the issue stems from the function skip_rear_comments, which was a work around to remove "extra" "*/" characters from the query text, when parsing a query and reusing the text fragments to represent a view, trigger, function or stored procedure. The reason for this work around is that "special comments", like /*!50002 XXX */, were not parsed properly, so that a query like: AAA /*!50002 BBB */ CCC would be seen by the parser as "AAA BBB */ CCC" when the current version is greater or equal to 5.0.2 The root cause of this stems from how special comments are parsed. Special comments are really out-of-bound text that appear inside a query, that affects how the parser behave. In nature, /*!50002 XXX */ in MySQL is similar to the C concept of preprocessing : #if VERSION >= 50002 XXX #endif Depending on the current VERSION of the server, either the special comment should be expanded or it should be ignored, but in all cases the "text" of the query should be re-written to strip the "/*!50002" and "*/" markers, which does not belong to the SQL language itself. Prior to this fix, these markers would leak into : - the storage format for VIEW, - the storage format for FUNCTION, - the storage format for FUNCTION parameters, in mysql.proc (param_list), - the storage format for PROCEDURE, - the storage format for PROCEDURE parameters, in mysql.proc (param_list), - the storage format for TRIGGER, - the binary log used for replication. In all cases, not only this cause format corruption, but also provide a vector for dormant security issues, by allowing to tunnel code that will be activated after an upgrade. The proper solution is to deal with special comments strictly during parsing, when accepting a query from the outside world. Once a query is parsed and an object is created with a persistant representation, this object should not arbitrarily mutate after an upgrade. In short, special comments are a useful but limited feature for MYSQLdump, when used at an *interface* level to facilitate import/export, but bloating the server *internal* storage format is *not* the proper way to deal with configuration management of the user logic. With this fix: - the Lex_input_stream class now acts as a comment pre-processor, and either expands or ignore special comments on the fly. - MYSQLlex and sql_yacc.yy have been cleaned up to strictly use the public interface of Lex_input_stream. In particular, how the input stream accepts or rejects a character is private to Lex_input_stream, and the internal buffer pointers of that class are strictly private, and should not be tempered with during parsing. This caused many changes mostly in sql_lex.cc. During the code cleanup in case MY_LEX_NUMBER_IDENT, Bug 28127 (Some valid identifiers names are not parsed correctly) was found and fixed. By parsing special comments properly, and removing the function 'skip_rear_comments' [sic], Bug 26302 (MySQL server cuts off trailing "*/" from comments in SP/func) has been fixed as well. sql/event_data_objects.cc: Cleanup of the code that extracts the query text sql/sp.cc: Cleanup of the code that extracts the query text sql/sp_head.cc: Cleanup of the code that extracts the query text sql/sql_trigger.cc: Cleanup of the code that extracts the query text sql/sql_view.cc: Cleanup of the code that extracts the query text mysql-test/r/comments.result: Bug#25411 (trigger code truncated) mysql-test/r/sp.result: Bug#25411 (trigger code truncated) Bug 26302 (MySQL server cuts off trailing "*/" from comments in SP/func) mysql-test/r/trigger.result: Bug#25411 (trigger code truncated) mysql-test/r/varbinary.result: Bug 28127 (Some valid identifiers names are not parsed correctly) mysql-test/t/comments.test: Bug#25411 (trigger code truncated) mysql-test/t/sp.test: Bug#25411 (trigger code truncated) Bug 26302 (MySQL server cuts off trailing "*/" from comments in SP/func) mysql-test/t/trigger.test: Bug#25411 (trigger code truncated) mysql-test/t/varbinary.test: Bug 28127 (Some valid identifiers names are not parsed correctly) sql/sql_lex.cc: Implemented comment pre-processing in Lex_input_stream, major cleanup of the lex/yacc code to not use Lex_input_stream private members. sql/sql_lex.h: Implemented comment pre-processing in Lex_input_stream, major cleanup of the lex/yacc code to not use Lex_input_stream private members. sql/sql_yacc.yy: post merge fix : view_check_options must be parsed before signaling the end of the query

The value of "low-priority-updates" option and the LOW PRIORITY prefix was taken into account at parse time. This caused triggers (among others) to ignore this flag (if supplied for the DML statement). Moved reading of the LOW_PRIORITY flag at run time. Fixed an incosistency when handling SET GLOBAL LOW_PRIORITY_UPDATES : now it is in effect for delayed INSERTs. Tested by checking the effect of LOW_PRIORITY flag via a trigger. include/thr_lock.h: Bug #26162: moved reading of the LOW PRIORITY flag at run time mysql-test/r/trigger.result: Bug #26162: test case mysql-test/t/trigger.test: Bug #26162: test case sql/set_var.cc: Bug #26162: fixed the handling of the "low-priority-updates" option sql/sql_base.cc: Bug #26162: moved reading of the LOW PRIORITY flag at run time sql/sql_yacc.yy: Bug #26162: moved reading of the LOW PRIORITY flag at run time

Bug#4968 ""Stored procedure crash if cursor opened on altered table" Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing" Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from stored procedure." Bug#19733 "Repeated alter, or repeated create/drop, fails" Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server" Bug#24879 "Prepared Statements: CREATE TABLE (UTF8 KEY) produces a growing key length" (this bug is not fixed in 5.0) Re-execution of CREATE DATABASE, CREATE TABLE and ALTER TABLE statements in stored routines or as prepared statements caused incorrect results (and crashes in versions prior to 5.0.25). In 5.1 the problem occured only for CREATE DATABASE, CREATE TABLE SELECT and CREATE TABLE with INDEX/DATA DIRECTOY options). The problem of bugs 4968, 19733, 19282 and 6895 was that functions mysql_prepare_table, mysql_create_table and mysql_alter_table are not re-execution friendly: during their operation they modify contents of LEX (members create_info, alter_info, key_list, create_list), thus making the LEX unusable for the next execution. In particular, these functions removed processed columns and keys from create_list, key_list and drop_list. Search the code in sql_table.cc for drop_it.remove() and similar patterns to find evidence. The fix is to supply to these functions a usable copy of each of the above structures at every re-execution of an SQL statement. To simplify memory management, LEX::key_list and LEX::create_list were added to LEX::alter_info, a fresh copy of which is created for every execution. The problem of crashing bug 22060 stemmed from the fact that the above metnioned functions were not only modifying HA_CREATE_INFO structure in LEX, but also were changing it to point to areas in volatile memory of the execution memory root. The patch solves this problem by creating and using an on-stack copy of HA_CREATE_INFO in mysql_execute_command. Additionally, this patch splits the part of mysql_alter_table that analizes and rewrites information from the parser into a separate function - mysql_prepare_alter_table, in analogy with mysql_prepare_table, which is renamed to mysql_prepare_create_table. mysql-test/r/ps.result: Update test results (Bug#19182, Bug#22060, Bug#4968, Bug#6895) mysql-test/r/sp.result: Update results (Bug#19733) mysql-test/t/ps.test: Add test cases for Bug#19182, Bug#22060, Bug#4968, Bug#6895 mysql-test/t/sp.test: Add a test case for Bug#19733 sql/field.h: Implement a deep copy constructor for create_field sql/mysql_priv.h: LEX::key_list and LEX::create_list were moved to LEX::alter_info. Update declarations to use LEX::alter_info instead of these two members. Remove declarations of mysql_add_index, mysql_drop_index. sql/sql_class.cc: Implement deep copy constructors. sql/sql_class.h: Implement (almost) deep copy constructors for key_part_spec, Alter_drop, Alter_column, Key, foreign_key. Replace pair<columns, keys> with an instance of Alter_info in select_create constructor. We create a new copy of Alter_info each time we re-execute SELECT .. CREATE prepared statement. sql/sql_insert.cc: Adjust to a new signature of create_table_from_items. sql/sql_lex.cc: Implement Alter_info::Alter_info that would make a "deep" copy of all definition lists (keys, columns). Move is_partition_management() from sql_partition.cc (feature-based file division is evil). sql/sql_lex.h: Move key_list and create_list to class Alter_info. Implement Alter_info::Alter_info that can be used with PS and SP. Get rid of Alter_info::clear() which was an attempt to save on matches and always use Alter_info::reset(). Implement an auxiliary Alter_info::init_for_create_from_alter() which is used in mysql_alter_table. sql/sql_list.cc: Implement a copy constructor of class List that makes a deep copy of all list nodes. sql/sql_list.h: Implement a way to make a deep copy of all list nodes. sql/sql_parse.cc: Adjust to new signatures of mysql_create_table, mysql_alter_table, select_create. Functions mysql_create_index and mysql_drop_index has become identical after initialization of alter_info was moved to the parser, and were merged. Flag enable_slow_log was not updated for SQLCOM_DROP_INDEX, which was a bug. Just like CREATE INDEX, DROP INDEX is currently done via complete table rebuild and is rightfully a slow administrative statement. sql/sql_partition.cc: Move is_partition_management() to sql_lex.cc Adjust code to the new Alter_info. sql/sql_table.cc: Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table, mysql_prepare_table to new signatures. Rename mysql_prepare_table to mysql_prepare_create_table. Make sure it follows the convention and returns FALSE for success and TRUE for error. Move parts of mysql_alter_table to mysql_prepare_alter_table. Move the first invokation of mysql_prepare_table from mysql_alter_table to compare_tables, as it was needed only for the purpose of correct comparison. Since now Alter_info itself is created in the runtime mem root, adjust mysql_prepare_table to always allocate memory in the runtime memory root. Remove dead code. sql/sql_yacc.yy: LEX::key_list and LEX::create_list moved to class Alter_info

Bug #23667 "CREATE TABLE LIKE is not isolated from alteration by other connections" Bug #18950 "CREATE TABLE LIKE does not obtain LOCK_open" As well as: Bug #25578 "CREATE TABLE LIKE does not require any privileges on source table". The first and the second bugs resulted in various errors and wrong binary log order when one tried to execute concurrently CREATE TABLE LIKE statement and DDL statements on source table or DML/DDL statements on its target table. The problem was caused by incomplete protection/table-locking against concurrent statements implemented in mysql_create_like_table() routine. We solve it by simply implementing such protection in proper way. Most of actual work for 5.1 was already done by fix for bug 20662 and preliminary patch changing locking in ALTER TABLE. The third bug allowed user who didn't have any privileges on table create its copy and therefore circumvent privilege check for SHOW CREATE TABLE. This patch solves this problem by adding privilege check, which was missing. Finally it also removes some duplicated code from mysql_create_like_table() and thus fixes bug #26869 "TABLE_LIST::table_name_length inconsistent with TABLE_LIST::table_name". mysql-test/r/create-big.result: Added test coverage for concurrency-related issues with CREATE TABLE LIKE. mysql-test/r/create.result: Adjusted error-code in the test case after refactoring code that implements CREATE TABLE ... LIKE. mysql-test/r/grant2.result: Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges on source table". mysql-test/t/create-big.test: Added test coverage for concurrency-related issues with CREATE TABLE LIKE. mysql-test/t/create.test: Adjusted error-code in the test case after refactoring code that implements CREATE TABLE ... LIKE. mysql-test/t/disabled.def: Recent code changes ensured that CREATE TABLE LIKE statement is properly isolated against other statements, so synchronization.test should no longer fail (see fix for bug 20662 and preliminary patch for bug 23667 changing ALTER TABLE locking). mysql-test/t/grant2.test: Added test for bug#25578 "CREATE TABLE LIKE does not require any privileges on source table". sql/handler.h: Introduced new flag for HA_CREATE_INFO::options in order to be able to distinguish CREATE TABLE ... LIKE from other types of CREATE TABLE. sql/mysql_priv.h: mysql_create_like_table() now takes source table name not as a Table_ident object but as regular table list element. sql/sql_lex.h: Removed LEX::like_name member. Now we use special flag in LEX::create_info::options for distinguishing CREATE TABLE ... LIKE from other types of CREATE TABLE and store name of source table as regular element in statement's table list. sql/sql_parse.cc: CREATE TABLE ... LIKE implementation now uses statement's table list for storing information about the source table. We also use flag in LEX::create_info.options for distinguishing it from other types of CREATE TABLE. Finally CREATE TABLE ... LIKE now requires the same privileges on the source tables as SHOW CREATE TABLE. Moved this privilege check to check_show_create_table_access() function. sql/sql_partition.cc: Now we use special flag in LEX::create_info::options for distinguishing CREATE TABLE ... LIKE from other types of CREATE TABLE and store name of source table as regular element in statement's table list. sql/sql_table.cc: mysql_create_like_table(): - Commented and cleaned-up a bit code which is responsible for achieving isolation from concurrent statements. Most of actual work was done by fix for bug 20662 and preliminary patch changing locking locking in ALTER TABLE, so here we do minor things like relaxing locking on source table (we don't need lock on it, to have it open is enough) and adjusting code to make it more friendly against code implementing I_S. - Get rid of duplicated code related to source database/table name handling. All these operations are already done in st_select_lex::add_table_to_list(), so we achieve the same effect by including source table into the statement's table list. sql/sql_yacc.yy: Now we use special flag in LEX::create_info::options for distinguishing CREATE TABLE ...

Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables" Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" Bug #24738 "CREATE TABLE ... SELECT is not isolated properly" Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" Deadlock occured when one tried to execute CREATE TABLE IF NOT EXISTS ... SELECT statement under LOCK TABLES which held read lock on target table. Attempt to execute the same statement for already existing target table with triggers caused server crashes. Also concurrent execution of CREATE TABLE ... SELECT statement and other statements involving target table suffered from various races (some of which might've led to deadlocks). Finally, attempt to execute CREATE TABLE ... SELECT in case when a temporary table with same name was already present led to the insertion of data into this temporary table and creation of empty non-temporary table. All above problems stemmed from the old implementation of CREATE TABLE ... SELECT in which we created, opened and locked target table without any special protection in a separate step and not with the rest of tables used by this statement. This underminded deadlock-avoidance approach used in server and created window for races. It also excluded target table from prelocking causing problems with trigger execution. The patch solves these problems by implementing new approach to handling of CREATE TABLE ... SELECT for base tables. We try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. We still use old approach for creation of temporary tables. Note that we have separate fix for 5.0 since there we use slightly different less intrusive approach. mysql-test/r/create.result: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/r/trigger.result: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" mysql-test/t/create.test: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/t/trigger.test: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" sql/lock.cc: Now for creation of name-lock placeholder lock_table_name() uses auxiliary function table_cache_insert_placeholder(). sql/mysql_priv.h: Removed declaration of non-existing build_table_path() routine. The former mysql_create_table_internal() was renamed to mysql_create_table_no_lock() and now exposed to other modules to give them opportunity of creation of tables in cases when name-lock is already obtained. reopen_name_locked_table() now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added declaration of auxiliary function table_cache_insert_placeholder() which is used for creation of table placeholders for name-locking. Added declaration of lock_table_name_if_not_cached() which can be used to take an exclusive name-lock on table if there are no records for it in table cache. Changed signature of unlink_open_table() function to simplify its use and make it useful for table placeholders and tables that are only open. Added auxiliary drop_open_table() routine. Moved declaration of refresh_version to table.h header to make it accessible from inline methods of TABLE class. MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead MYSQL_OPEN_TEMPORARY_ONLY option was added. sql/sql_base.cc: Added support for the new approach to the handling of CREATE TABLE ... SELECT for base tables. Now we try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. Note significant distinctions of this placeholder from the placeholder used for normal name-lock: 1) It is treated like open table by other name-locks so it does not allow name-lock taking operations like DROP TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables list and automatically removed during close_thread_tables() call open_tables(): Implemented logic described above. To do this added auxiliary check_if_table_exists() function. Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option which is no longer used. Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict search for temporary tables only. close_cached_tables()/close_thread_table()/reopen_tables()/ close_old_data_files()/table_is_used()/remove_table_from_cache(): Added support for open placeholders (note that we also use them when we need to re-open tables during flush). unlink_open_table(): Changed function signature to simplify its use and to make useful for open placeholders and tables which are only open and not locked. Added auxiliary drop_open_table() routine. reopen_name_locked_table(): Now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added auxiliary table_cache_insert_placeholder() routine which simplifies creation of placeholders used for name-locking. Added lock_table_name_if_not_cached() which can be used to take an exclusive name-lock on table if there are no records for it in table cache. sql/sql_handler.cc: Adjusted mysql_ha_mark_tables_for_reopen() routine to properly handle placeholders which now can be linked into open tables list. sql/sql_insert.cc: Introduced new approach to handling of base tables in CREATE TABLE ... SELECT statement. Now we try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. By doing this we avoid races which existed with previous approach in which we created, opened and locked target in separate step without any special protection. This also allows properly calculate prelocking set in cases when target table already exists and has some on insert triggers. Note that we don't employ the same approach for temporary tables (this is okay as such tables are unaffected by other threads). Changed create_table_from_items() and methods of select_create class to implement this approach. sql/sql_parse.cc: The new approach to handling of CREATE TABLE ... SELECT for base tables assumes that all tables (including table to be created) are opened and (or) locked at the same time. So in cases when we create base table we have to pass to open_and_lock_tables() table list which includes target table. sql/sql_prepare.cc: The new approach to handling of CREATE TABLE ... SELECT for base tables assumes that all tables (including table to be created) are opened and (or) locked at the same time. So in cases when we create base table we have to pass to open_and_lock_tables() table list which includes target table. sql/sql_table.cc: Changed mysql_create_table(), mysql_create_like_table() and mysql_alter_table() (in rename case) to obtain exclusive name-lock on the non-temporary table which is going to be created (to which we going to rename). This ensures that not only destination table doesn't exist on disk but also that there are no placeholder in table cache for it (i.e. there is no CREATE TABLE ... SELECT operation in progress for it). Note that to avoid deadlocks while taking these name-locks this code assumes that existence of any record for table in table cache (even name-lock) means that table exists. Altough such check can lead to false positives these should occur only in case of highly concurrent DDL operations on the table and should not break binary logging. Renamed mysql_create_table_internal() to mysql_create_table_no_lock() and made it accessible from other files to give them ability to create table in situation when name-lock is already obtained or not relevant. Adjusted calls to reopen_name_locked_table(), which now takes extra argument, which controls linking of open table into THD::open_tables list. Removed redundant setting of table's 'version' field before calls to close_cached_table(). This function will set it to 0 itself anyway. sql/sql_trigger.cc: reopen_name_locked_tables() now has one more argument which controls linking of opened table into the THD::open_tables list. sql/sql_yacc.yy: The new approach to handling of CREATE TABLE ... SELECT statement for base tables assumes that all tables including table to be created are open and (or) locked at the same time. Therefore we need to set correct lock for target table. sql/table.h: Moved declaration of refresh_version variable from mysql_priv.h to make it accessible from inline methods of TABLE class. Renamed TABLE::locked_by_flush member to open_placeholder since now it is also used for taking exclusive name-lock and not only by flush. Introduced TABLE::is_name_opened() helper method which can be used to distinguish TABLE instances corresponding to open tables or placeholders for them from closed instances (e.g. due to their old version). Also introduced TABLE::needs_reopen_or_name_lock() helper which allows to check if TABLE instance corresponds to outdated version of table or to name-lock placeholder. Introduced TABLE_LIST::create member which marks elements of table list corresponds to the table to be created. Adjusted TABLE_LIST::placeholder() method to take into account name-lock placeholders for tables to be created (this, for example, allows to properly handle such placeholders in lock_tables()). Finally, moved currently unused TABLE::open_next/open_prev members under ifdef NOT_YET. mysql-test/r/create_select-big.result: New BitKeeper file ``mysql-test/r/create_select-big.result'' mysql-test/t/create_select-big.test: New BitKeeper file ``mysql-test/t/create_select-big.test''

Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables" Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" Bug #24738 "CREATE TABLE ... SELECT is not isolated properly" Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" Deadlock occured when one tried to execute CREATE TABLE IF NOT EXISTS ... SELECT statement under LOCK TABLES which held read lock on target table. Attempt to execute the same statement for already existing target table with triggers caused server crashes. Also concurrent execution of CREATE TABLE ... SELECT statement and other statements involving target table suffered from various races (some of which might've led to deadlocks). Finally, attempt to execute CREATE TABLE ... SELECT in case when a temporary table with same name was already present led to the insertion of data into this temporary table and creation of empty non-temporary table. All above problems stemmed from the old implementation of CREATE TABLE ... SELECT in which we created, opened and locked target table without any special protection in a separate step and not with the rest of tables used by this statement. This underminded deadlock-avoidance approach used in server and created window for races. It also excluded target table from prelocking causing problems with trigger execution. The patch solves these problems by implementing new approach to handling of CREATE TABLE ... SELECT for base tables. We try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. We still use old approach for creation of temporary tables. Also note that we decided to postpone introduction of some tests for concurrent behaviour of CREATE TABLE ... SELECT till 5.1. The main reason for this is absence in 5.0 ability to set @@debug variable at runtime, which can be circumvented only by using several test files with individual .opt files. Since the latter is likely to slowdown test-suite unnecessary we chose not to push this tests into 5.0, but run them manually for this version and later push their optimized version into 5.1 mysql-test/r/create.result: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/r/trigger.result: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" mysql-test/t/create.test: Extended test coverage for CREATE TABLE ... SELECT. In particular added tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when temporary table exists" and bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT with locked tables". mysql-test/t/trigger.test: Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers" sql/lock.cc: Now for creation of name-lock placeholder in lock_table_name() we use auxiliary function table_cache_insert_placeholder(). sql/mysql_priv.h: Made build_table_path() function available outside of sql_table.cc file. reopen_name_locked_table() now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added declaration of auxiliary function table_cache_insert_placeholder() which is used for creation of table placeholders for name-locking. Added declaration of table_cache_has_open_placeholder() function which can be used for checking if table cache contains an open placeholder for the table and if this placeholder was created by another thread. (This function is needed only in 5.0 where we use it in various versions of CREATE TABLE in order to protect it from concurrent CREATE TABLE ... SELECT operations for the table. Starting from 5.1 we use different approach so it is going to be removed there). Made close_old_data_files() static within sql_base.cc file. Added auxiliary drop_open_table() routine. Moved declaration of refresh_version to table.h header to make it accessible from inline methods of TABLE class. MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead MYSQL_OPEN_TEMPORARY_ONLY option was added. sql/sql_base.cc: Added support for the new approach to the handling of CREATE TABLE ... SELECT for base tables. Now we try to open and lock table to be created at the same time as the rest of tables used by this statement. If such table does not exist at this moment we create and place in the table cache special placeholder for it which prevents its creation or any other usage by other threads. Note significant distinctions of this placeholder from the placeholder used for normal name-lock: 1) It is treated like open table by other name-locks so it does not allow name-lock taking operations like DROP TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables list and automatically removed during close_thread_tables() call. open_tables(): Implemented logic described above. To do this added auxiliary check_if_table_exists() function. Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option which is no longer used. Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict search for temporary tables only. close_cached_tables()/close_thread_table()/reopen_tables()/ close_old_data_files()/table_is_used()/remove_table_from_cache(): Added support for open placeholders (note that we also use them when we need to re-open tables during flush). Added auxiliary drop_open_table() routine. reopen_name_locked_table(): Now has 3rd argument which controls linking in of table being opened into THD::open_tables (this is useful in cases when placeholder used for name-locking is already linked into this list). Added auxiliary table_cache_insert_placeholder() routine which simplifies creation of placeholders used for name-locking. Added table_cache_has_open_placeholder() function which can be used for checking if table cache contains an open placeholder for the table and if this placeholder was created by another thread. (This function is needed only in 5.0 where we use it in various versions of CREATE TABLE in order to protect it from concurrent CREATE TABLE ... SELECT operations for the table.

So in cases when we create base table we have to pass to open_and_lock_tables() table list which includes target table. sql/sql_table.cc: Now mysql_create_table_internal(), mysql_create_like_table() and mysql_alter_table() not only check that destination table doesn't exist on disk but also check that there is no create placeholder in table cache for it (i.e. there is no CREATE TABLE ... SELECT operation in progress for it). Note that starting from 5.1 we use different approach in order to to protect CREATE TABLE ... SELECT from concurrent CREATE TABLE (ALTER TABLE ... RENAME) operations, the latter simply take name-locks on table before its creation (on target table name before renaming). Also made build_table_path() available from other files and asjusted calls to reopen_name_locked_table(), which now takes extra argument, which controls linking of open table into THD::open_tables list. sql/sql_trigger.cc: reopen_name_locked_tables() now has one more argument which controls linking of opened table into the THD::open_tables list. sql/sql_yacc.yy: The new approach to handling of CREATE TABLE ...

The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar* to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c BitKeeper/etc/ignore: added libmysqld/ha_ndbcluster_cond.cc --- added debian/defs.mk debian/control
