Enable support of access to tables from triggers. Thus fix bug #8406 "Triggers crash if referencing a table" and several other related bugs. Fix for bug #11834 "Re-execution of prepared statement with dropped function crashes server." which was spotted during work on previous bugs. Also couple of nice cleanups: - Replaced two separate hashes for stored routines used by statement with one. - Now instead of doing one pass through all routines used in statement for caching them and then doing another pass for adding their tables to table list, we do only one pass during which do both things. mysql-test/r/sp-error.result: Added test for bug #11834 "Re-execution of prepared statement with dropped function crashes server" also covering handling of prepared statements which use stored functions but does not require prelocking. mysql-test/r/sp.result: Updated test for LOCK TABLES with views in table list. (Old version of statement used in this test will work ok now, since prelocking algorithm was tuned and will lock only one multi-set of tables for each routine even if this routine is used in several different views). mysql-test/r/trigger.result: Added several tests for triggers using tables. mysql-test/t/sp-error.test: Added test for bug #11834 "Re-execution of prepared statement with dropped function crashes server" also covering handling of prepared statements which use stored functions but does not require prelocking. mysql-test/t/sp.test: Updated comment about recursive views to reflect current situation. Updated test for LOCK TABLES with views in table list. (Old version of statement used in this test will work ok now, since prelocking algorithm was tuned and will lock only one multi-set of tables for each routine even if this routine is used in several different views). mysql-test/t/trigger.test: Added several tests for triggers using tables. sql/item_func.cc: Item_func_sp::cleanup(): By next statement execution stored function can be dropped or altered so we can't assume that sp_head object for it will be still valid. sql/sp.cc: - Added Sroutine_hash_entry structure that represents element in the set of stored routines used by statement or routine. We can't as before use LEX_STRING for this purprose because we want link all elements of this set in list. - Replaced sp_add_to_hash() with sp_add_used_routine() which takes into account that now we use one hash for stored routines used by statement instead of two and which mantains list linking all elelemnts in this hash. - Renamed sp_merge_hash() to sp_update_sp_used_routines(). - Introduced sp_update_stmt_used_routines() for adding elements to the set of routines used by statement from another similar set for statement or routine. This function will also mantain list linking elements of destination set. - Now instead of one sp_cache_routines() function we have family of sp_cache_routines_and_add_tables() functions which are also responsible for adding tables used by routines being cached to statement table list. Nice optimization - thanks to list linking all elements in the hash of routines used by statement we don't need to perform several iterations over this hash (as it was before in cases when we have added new elements to it). sql/sp.h: Added declarations of functions used for manipulations with set (hash) of stored routines used by statement. sql/sp_head.cc: sp_name::init_qname(): Now sp_name also holds key identifying routine in the set (hash) of stored routines used by statement. sp_head: Instead of two separate hashes sp_funs/m_spprocs representing sets of stored routines used by this routine we use one hash - m_sroutines. sp_instr_set_trigger_field: Added support for subqueries in assignments to row accessors in triggers. Removed definition of sp_add_sp_tables_to_table_list() and auxilary functions since now we don't have separate stage on which we add tables used by routines used by statement to table list for prelocking. We do it on the same stage as we load those routines in SP cache. So all this functionality moved to sp_cache_routines_and_add_tables() family of functions. sql/sp_head.h: sp_name: Now this class also holds key identifying routine in the set (hash) of stored routines used by statement. sp_head: Instead of two separate hashes sp_funs/m_spprocs representing sets of stored routines used by this routine we use one hash - m_sroutines. sp_instr_set_trigger_field: Added support for subqueries in assignments to row accessors in triggers. Removed declaration of sp_add_sp_tables_to_table_list() since now we don't have separate stage on which we add tables used by routines used by statement to table list for prelocking. We do it on the same stage as we load those routines in SP cache. sql/sql_base.cc: open_tables(): - LEX::spfuns/spprocs hashes were replaced with one LEX::sroutines hash. - Now instead of doing one pass through all routines used in statement for caching them and then doing another pass for adding their tables to table list, we do only one pass during which do both things. It is easy to do since all routines in the set of routines used by statement are linked in the list. This also allows us to calculate table list for prelocking more precisely. - Now triggers properly inform prelocking algorithm about tables they use. sql/sql_lex.cc: lex_start(): Replaced LEX::spfuns/spprocs with with one LEX::sroutines hash. Added LEX::sroutines_list list linking all elements in this hash. st_lex::st_lex(): Moved definition of LEX constructor to sql_lex.cc file to be able use sp_sroutine_key declaration from sp.h in it. sql/sql_lex.h: LEX: Replaced two separate hashes for stored routines used by statement with one. Added list linking all elements in this hash to be able to iterate through all elements and add new elements to this hash at the same time. Moved constructor definition to sql_lex.cc. sql/sql_parse.cc: mysql_execute_command(): Replaced LEX::spfuns/spprocs with one LEX::sroutines hash. sql/sql_trigger.cc: Added missing GNU GPL notice. Table_triggers_list::check_n_load() Added initialization of sroutines_key which stores key representing triggers of this table in the set (hash) of routines used by this statement. sql/sql_trigger.h: Added missing GNU GPL notice. Table_triggers_list: Added sroutines_key member to store key representing triggers of this table in the set (hash) of routines used by this statement. Declared sp_cache_routines_and_add_tables_for_triggers() as friend since it needs access to sroutines_key and trigger bodies. sql/sql_yacc.yy: - Now we use sp_add_used_routine() instead of sp_add_to_hash() for adding elements to the set of stored routines used in statement. - Enabled support of subqueries as right sides in assignments to triggers' row accessors.

NOTE
This function is mainly responsible for opening and locking of table and
invalidation of all its instances in table cache after trigger creation.
Real work on trigger creation/dropping is done inside Table_triggers_list
methods.

bool mysql_create_or_drop_trigger(THD *thd, TABLE_LIST *tables, bool create)
WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. Added comment clarifying why we don't need set no_send_ok when calling stored functions. sql/item_func.h: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. sql/lex.h: Symbols used in statements defining triggers were added. sql/mysql_priv.h: Exported some functions needed for triggers implementation. sql/parse_file.cc: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/parse_file.h: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/share/czech/errmsg.txt: Added trigger related error messages. sql/share/danish/errmsg.txt: Added trigger related error messages. sql/share/dutch/errmsg.txt: Added trigger related error messages. sql/share/english/errmsg.txt: Added trigger related error messages. sql/share/estonian/errmsg.txt: Added trigger related error messages. sql/share/french/errmsg.txt: Added trigger related error messages. sql/share/german/errmsg.txt: Added trigger related error messages. sql/share/greek/errmsg.txt: Added trigger related error messages. sql/share/hungarian/errmsg.txt: Added trigger related error messages. sql/share/italian/errmsg.txt: Added trigger related error messages. sql/share/japanese/errmsg.txt: Added trigger related error messages. sql/share/korean/errmsg.txt: Added trigger related error messages. sql/share/norwegian-ny/errmsg.txt: Added trigger related error messages. sql/share/norwegian/errmsg.txt: Added trigger related error messages. sql/share/polish/errmsg.txt: Added trigger related error messages. sql/share/portuguese/errmsg.txt: Added trigger related error messages. sql/share/romanian/errmsg.txt: Added trigger related error messages. sql/share/russian/errmsg.txt: Added trigger related error messages. sql/share/serbian/errmsg.txt: Added trigger related error messages. sql/share/slovak/errmsg.txt: Added trigger related error messages. sql/share/spanish/errmsg.txt: Added trigger related error messages. sql/share/swedish/errmsg.txt: Added trigger related error messages. sql/share/ukrainian/errmsg.txt: Added trigger related error messages. sql/sp_head.cc: sp_head::init_strings(): added support for triggers (we don't have most of strings for them) sp_head::execute_function(): triggers don't require RETURN sp_head::reset_lex(): added propagation of trigger properties to LEX used for parsing of statements composing trigger body.

Added initialization of LEX->trg_table to lex_start(). (When triggers are parsed during opening of table it points to table object.) sql/sql_lex.h: Added trigger related commands. Added st_trg_chistics structure describing properties of trigger being created (as struct and as LEX member).

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. Added comment clarifying why we don't need set no_send_ok when calling stored functions. sql/item_func.h: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. sql/lex.h: Symbols used in statements defining triggers were added. sql/mysql_priv.h: Exported some functions needed for triggers implementation. sql/parse_file.cc: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/parse_file.h: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/share/czech/errmsg.txt: Added trigger related error messages. sql/share/danish/errmsg.txt: Added trigger related error messages. sql/share/dutch/errmsg.txt: Added trigger related error messages. sql/share/english/errmsg.txt: Added trigger related error messages. sql/share/estonian/errmsg.txt: Added trigger related error messages. sql/share/french/errmsg.txt: Added trigger related error messages. sql/share/german/errmsg.txt: Added trigger related error messages. sql/share/greek/errmsg.txt: Added trigger related error messages. sql/share/hungarian/errmsg.txt: Added trigger related error messages. sql/share/italian/errmsg.txt: Added trigger related error messages. sql/share/japanese/errmsg.txt: Added trigger related error messages. sql/share/korean/errmsg.txt: Added trigger related error messages. sql/share/norwegian-ny/errmsg.txt: Added trigger related error messages. sql/share/norwegian/errmsg.txt: Added trigger related error messages. sql/share/polish/errmsg.txt: Added trigger related error messages. sql/share/portuguese/errmsg.txt: Added trigger related error messages. sql/share/romanian/errmsg.txt: Added trigger related error messages. sql/share/russian/errmsg.txt: Added trigger related error messages. sql/share/serbian/errmsg.txt: Added trigger related error messages. sql/share/slovak/errmsg.txt: Added trigger related error messages. sql/share/spanish/errmsg.txt: Added trigger related error messages. sql/share/swedish/errmsg.txt: Added trigger related error messages. sql/share/ukrainian/errmsg.txt: Added trigger related error messages. sql/sp_head.cc: sp_head::init_strings(): added support for triggers (we don't have most of strings for them) sp_head::execute_function(): triggers don't require RETURN sp_head::reset_lex(): added propagation of trigger properties to LEX used for parsing of statements composing trigger body. Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sp_head.h: Added new type of sp_head object - TYPE_ENUM_TRIGGER Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sql_base.cc: Now freeing memory occupied by trigger related structures when closing tables. open_unireg_entry(): added loading of triggers for table. find_field_in_real_table() is now public since it required by Item_trigger_field in item.cc sql/sql_delete.cc: Added triggers invocation for DELETE (should be fixed for sure :)) sql/sql_insert.cc: Added triggers invocation for INSERT (should be fixed for sure :)) sql/sql_lex.cc: Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added initialization of LEX->trg_table to lex_start(). (When triggers are parsed during opening of table it points to table object.) sql/sql_lex.h: Added trigger related commands. Added st_trg_chistics structure describing properties of trigger being created (as struct and as LEX member). Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added LEX::trg_table which points to table being opened when we are parsing trigger definition while opening table. sql/sql_parse.cc: Added support for CREATE/DROP TRIGGER commands. sql/sql_table.cc: Cleanup. close_cached_table() always returns 0 and its result is not analyzed in most places so chenged its return type to void. sql/sql_update.cc: Added triggers invocation for UPDATE (should be fixed for sure :)) sql/sql_yacc.yy: Added support for CREATE/DROP TRIGGER statements. Added support for OLD/NEW row identifiers in trigger. Made assignment to user variables not to break execution of stored function or trigger. sql/table.h: Added TABLE::triggers member representing triggers for this table.

Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sp_head.h: Added new type of sp_head object - TYPE_ENUM_TRIGGER Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sql_base.cc: Now freeing memory occupied by trigger related structures when closing tables. open_unireg_entry(): added loading of triggers for table. find_field_in_real_table() is now public since it required by Item_trigger_field in item.cc sql/sql_delete.cc: Added triggers invocation for DELETE (should be fixed for sure :)) sql/sql_insert.cc: Added triggers invocation for INSERT (should be fixed for sure :)) sql/sql_lex.cc: Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added initialization of LEX->trg_table to lex_start(). (When triggers are parsed during opening of table it points to table object.) sql/sql_lex.h: Added trigger related commands. Added st_trg_chistics structure describing properties of trigger being created (as struct and as LEX member). Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added LEX::trg_table which points to table being opened when we are parsing trigger definition while opening table. sql/sql_parse.cc: Added support for CREATE/DROP TRIGGER commands. sql/sql_table.cc: Cleanup. close_cached_table() always returns 0 and its result is not analyzed in most places so chenged its return type to void. sql/sql_update.cc: Added triggers invocation for UPDATE (should be fixed for sure :)) sql/sql_yacc.yy: Added support for CREATE/DROP TRIGGER statements. Added support for OLD/NEW row identifiers in trigger. Made assignment to user variables not to break execution of stored function or trigger. sql/table.h: Added TABLE::triggers member representing triggers for this table.

DBUG_RETURN(TRUE);
WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. Added comment clarifying why we don't need set no_send_ok when calling stored functions. sql/item_func.h: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. sql/lex.h: Symbols used in statements defining triggers were added. sql/mysql_priv.h: Exported some functions needed for triggers implementation. sql/parse_file.cc: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/parse_file.h: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/share/czech/errmsg.txt: Added trigger related error messages. sql/share/danish/errmsg.txt: Added trigger related error messages. sql/share/dutch/errmsg.txt: Added trigger related error messages. sql/share/english/errmsg.txt: Added trigger related error messages. sql/share/estonian/errmsg.txt: Added trigger related error messages. sql/share/french/errmsg.txt: Added trigger related error messages. sql/share/german/errmsg.txt: Added trigger related error messages. sql/share/greek/errmsg.txt: Added trigger related error messages. sql/share/hungarian/errmsg.txt: Added trigger related error messages. sql/share/italian/errmsg.txt: Added trigger related error messages. sql/share/japanese/errmsg.txt: Added trigger related error messages. sql/share/korean/errmsg.txt: Added trigger related error messages. sql/share/norwegian-ny/errmsg.txt: Added trigger related error messages. sql/share/norwegian/errmsg.txt: Added trigger related error messages. sql/share/polish/errmsg.txt: Added trigger related error messages. sql/share/portuguese/errmsg.txt: Added trigger related error messages. sql/share/romanian/errmsg.txt: Added trigger related error messages. sql/share/russian/errmsg.txt: Added trigger related error messages. sql/share/serbian/errmsg.txt: Added trigger related error messages. sql/share/slovak/errmsg.txt: Added trigger related error messages. sql/share/spanish/errmsg.txt: Added trigger related error messages. sql/share/swedish/errmsg.txt: Added trigger related error messages. sql/share/ukrainian/errmsg.txt: Added trigger related error messages. sql/sp_head.cc: sp_head::init_strings(): added support for triggers (we don't have most of strings for them) sp_head::execute_function(): triggers don't require RETURN sp_head::reset_lex(): added propagation of trigger properties to LEX used for parsing of statements composing trigger body.

Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sp_head.h: Added new type of sp_head object - TYPE_ENUM_TRIGGER Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sql_base.cc: Now freeing memory occupied by trigger related structures when closing tables. open_unireg_entry(): added loading of triggers for table. find_field_in_real_table() is now public since it required by Item_trigger_field in item.cc sql/sql_delete.cc: Added triggers invocation for DELETE (should be fixed for sure :)) sql/sql_insert.cc: Added triggers invocation for INSERT (should be fixed for sure :)) sql/sql_lex.cc: Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable.

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). mysql-test/r/trigger.result: Added test which attempts to create trigger for table referencing to field which does not exist in this table. mysql-test/t/trigger.test: Added test which attempts to create trigger for table referencing to field which does not exist in this table. sql/item.cc: Item_trigger_field::setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/item.h: Item_trigger_field: - Added next_trg_field member for linking all such objects in trigger in one list. - Also setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/mysql_priv.h: Added SQL_LIST::push_back() method which allows to add another SQL_LIST to the end of this SQL_LIST. sql/sp_head.cc: sp_head::init()/reset_lex()/restore_lex(): In order to fill global LEX::trg_table_fields (list of all Item_trigger_field objects for trigger) we should init the same list in LEX of substatement before its parsing and merge it to global list after parsing. sql/sp_head.h: sp_instr_trigger_field: Made trigger_field member public to be able to add it more easily to global list of all Item_trigger_field objects in trigger. sql/sql_lex.cc: LEX::trg_table was removed. sql/sql_lex.h: Now we are binding Item_trigger_field's to TABLE object by passing through specially constructed list of all such objects in this trigger instead of doing this during trigger definition parsing at table open. So we no longer need LEX::trg_table, we use LEX::trg_table_fields list instead. sql/sql_parse.cc: mysql_execute_command(): Since now we use trigger body for some checks in mysql_create_or_drop_trigger() we should destroy it only after calling this function. sql/sql_trigger.cc: Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). Table_triggers_list::prepare_old_row_accessors() method was added to be able to reuse code creating Field objects referencing TABLE::record[1] buffer instead of TABLE::record[0]. sql/sql_trigger.h: Added Table_triggers_list::prepare_old_row_accessors() method to be able to reuse code creating Field objects referencing to TABLE::record[1] instead of record[0]. sql/sql_yacc.yy: Now instead of performing binding of Item_trigger_field objects to TABLE object during trigger definition parsing at table open, we perform this binding by passing through specially constructed list of all such items in trigger. We also check value returned from memory allocation functions.

Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open.

/*
Let us check if all references to fields in old/new versions of row in
this trigger are ok.
NOTE: We do it here more from ease of use standpoint. We still have to
do some checks on each execution. E.g. we can catch privilege changes
only during execution. Also in near future, when we will allow access
to other tables from trigger we won't be able to catch changes in other
tables...
Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array.

And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions.

Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances.

And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).
2005-05-24 20:19:33 +02:00
Since we don't plan to access to contents of the fields it does not
matter that we choose for both OLD and NEW values the same versions
of Field objects here.
Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open.

And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

trg_field->fix_fields(thd, (Item **)0))
Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). mysql-test/r/trigger.result: Added test which attempts to create trigger for table referencing to field which does not exist in this table. mysql-test/t/trigger.test: Added test which attempts to create trigger for table referencing to field which does not exist in this table. sql/item.cc: Item_trigger_field::setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/item.h: Item_trigger_field: - Added next_trg_field member for linking all such objects in trigger in one list. - Also setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/mysql_priv.h: Added SQL_LIST::push_back() method which allows to add another SQL_LIST to the end of this SQL_LIST. sql/sp_head.cc: sp_head::init()/reset_lex()/restore_lex(): In order to fill global LEX::trg_table_fields (list of all Item_trigger_field objects for trigger) we should init the same list in LEX of substatement before its parsing and merge it to global list after parsing. sql/sp_head.h: sp_instr_trigger_field: Made trigger_field member public to be able to add it more easily to global list of all Item_trigger_field objects in trigger. sql/sql_lex.cc: LEX::trg_table was removed. sql/sql_lex.h: Now we are binding Item_trigger_field's to TABLE object by passing through specially constructed list of all such objects in this trigger instead of doing this during trigger definition parsing at table open. So we no longer need LEX::trg_table, we use LEX::trg_table_fields list instead. sql/sql_parse.cc: mysql_execute_command(): Since now we use trigger body for some checks in mysql_create_or_drop_trigger() we should destroy it only after calling this function. sql/sql_trigger.cc: Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). Table_triggers_list::prepare_old_row_accessors() method was added to be able to reuse code creating Field objects referencing TABLE::record[1] buffer instead of TABLE::record[0]. sql/sql_trigger.h: Added Table_triggers_list::prepare_old_row_accessors() method to be able to reuse code creating Field objects referencing to TABLE::record[1] instead of record[0]. sql/sql_yacc.yy: Now instead of performing binding of Item_trigger_field objects to TABLE object during trigger definition parsing at table open, we perform this binding by passing through specially constructed list of all such items in trigger. We also check value returned from memory allocation functions.

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures.

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties.

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open.

This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open.

Table_triggers_list::prepare_old_row_accessors() method was added to be able to reuse code creating Field objects referencing TABLE::record[1] buffer instead of TABLE::record[0]. sql/sql_trigger.h: Added Table_triggers_list::prepare_old_row_accessors() method to be able to reuse code creating Field objects referencing to TABLE::record[1] instead of record[0]. sql/sql_yacc.yy: Now instead of performing binding of Item_trigger_field objects to TABLE object during trigger definition parsing at table open, we perform this binding by passing through specially constructed list of all such items in trigger.

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ...

SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances.

Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances.

Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

Prepare array of Field objects referencing to TABLE::record[1] instead
of record[0] (they will represent OLD.* row values in ON UPDATE trigger
and in ON DELETE trigger which will be called during REPLACE execution).

During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

bool Table_triggers_list::prepare_record1_accessors(TABLE *table)
Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). mysql-test/r/trigger.result: Added test which attempts to create trigger for table referencing to field which does not exist in this table. mysql-test/t/trigger.test: Added test which attempts to create trigger for table referencing to field which does not exist in this table. sql/item.cc: Item_trigger_field::setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/item.h: Item_trigger_field: - Added next_trg_field member for linking all such objects in trigger in one list. - Also setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/mysql_priv.h: Added SQL_LIST::push_back() method which allows to add another SQL_LIST to the end of this SQL_LIST. sql/sp_head.cc: sp_head::init()/reset_lex()/restore_lex(): In order to fill global LEX::trg_table_fields (list of all Item_trigger_field objects for trigger) we should init the same list in LEX of substatement before its parsing and merge it to global list after parsing. sql/sp_head.h: sp_instr_trigger_field: Made trigger_field member public to be able to add it more easily to global list of all Item_trigger_field objects in trigger. sql/sql_lex.cc: LEX::trg_table was removed. sql/sql_lex.h: Now we are binding Item_trigger_field's to TABLE object by passing through specially constructed list of all such objects in this trigger instead of doing this during trigger definition parsing at table open. So we no longer need LEX::trg_table, we use LEX::trg_table_fields list instead. sql/sql_parse.cc: mysql_execute_command(): Since now we use trigger body for some checks in mysql_create_or_drop_trigger() we should destroy it only after calling this function. sql/sql_trigger.cc: Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger.

(i.e. now we allow to open tables with broken triggers). Table_triggers_list::prepare_old_row_accessors() method was added to be able to reuse code creating Field objects referencing TABLE::record[1] buffer instead of TABLE::record[0]. sql/sql_trigger.h: Added Table_triggers_list::prepare_old_row_accessors() method to be able to reuse code creating Field objects referencing to TABLE::record[1] instead of record[0]. sql/sql_yacc.yy: Now instead of performing binding of Item_trigger_field objects to TABLE object during trigger definition parsing at table open, we perform this binding by passing through specially constructed list of all such items in trigger.

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ...

Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances.

Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code.

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies).

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies).

Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sp_head.h: Added new type of sp_head object - TYPE_ENUM_TRIGGER Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sql_base.cc: Now freeing memory occupied by trigger related structures when closing tables. open_unireg_entry(): added loading of triggers for table. find_field_in_real_table() is now public since it required by Item_trigger_field in item.cc sql/sql_delete.cc: Added triggers invocation for DELETE (should be fixed for sure :)) sql/sql_insert.cc: Added triggers invocation for INSERT (should be fixed for sure :)) sql/sql_lex.cc: Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable.

Enable support of access to tables from triggers. Thus fix bug #8406 "Triggers crash if referencing a table" and several other related bugs. Fix for bug #11834 "Re-execution of prepared statement with dropped function crashes server." which was spotted during work on previous bugs. Also couple of nice cleanups: - Replaced two separate hashes for stored routines used by statement with one. - Now instead of doing one pass through all routines used in statement for caching them and then doing another pass for adding their tables to table list, we do only one pass during which do both things. mysql-test/r/sp-error.result: Added test for bug #11834 "Re-execution of prepared statement with dropped function crashes server" also covering handling of prepared statements which use stored functions but does not require prelocking. mysql-test/r/sp.result: Updated test for LOCK TABLES with views in table list. (Old version of statement used in this test will work ok now, since prelocking algorithm was tuned and will lock only one multi-set of tables for each routine even if this routine is used in several different views). mysql-test/r/trigger.result: Added several tests for triggers using tables. mysql-test/t/sp-error.test: Added test for bug #11834 "Re-execution of prepared statement with dropped function crashes server" also covering handling of prepared statements which use stored functions but does not require prelocking. mysql-test/t/sp.test: Updated comment about recursive views to reflect current situation. Updated test for LOCK TABLES with views in table list. (Old version of statement used in this test will work ok now, since prelocking algorithm was tuned and will lock only one multi-set of tables for each routine even if this routine is used in several different views). mysql-test/t/trigger.test: Added several tests for triggers using tables. sql/item_func.cc: Item_func_sp::cleanup(): By next statement execution stored function can be dropped or altered so we can't assume that sp_head object for it will be still valid. sql/sp.cc: - Added Sroutine_hash_entry structure that represents element in the set of stored routines used by statement or routine. We can't as before use LEX_STRING for this purprose because we want link all elements of this set in list. - Replaced sp_add_to_hash() with sp_add_used_routine() which takes into account that now we use one hash for stored routines used by statement instead of two and which mantains list linking all elelemnts in this hash. - Renamed sp_merge_hash() to sp_update_sp_used_routines(). - Introduced sp_update_stmt_used_routines() for adding elements to the set of routines used by statement from another similar set for statement or routine. This function will also mantain list linking elements of destination set. - Now instead of one sp_cache_routines() function we have family of sp_cache_routines_and_add_tables() functions which are also responsible for adding tables used by routines being cached to statement table list. Nice optimization - thanks to list linking all elements in the hash of routines used by statement we don't need to perform several iterations over this hash (as it was before in cases when we have added new elements to it). sql/sp.h: Added declarations of functions used for manipulations with set (hash) of stored routines used by statement. sql/sp_head.cc: sp_name::init_qname(): Now sp_name also holds key identifying routine in the set (hash) of stored routines used by statement. sp_head: Instead of two separate hashes sp_funs/m_spprocs representing sets of stored routines used by this routine we use one hash - m_sroutines. sp_instr_set_trigger_field: Added support for subqueries in assignments to row accessors in triggers. Removed definition of sp_add_sp_tables_to_table_list() and auxilary functions since now we don't have separate stage on which we add tables used by routines used by statement to table list for prelocking. We do it on the same stage as we load those routines in SP cache. So all this functionality moved to sp_cache_routines_and_add_tables() family of functions. sql/sp_head.h: sp_name: Now this class also holds key identifying routine in the set (hash) of stored routines used by statement. sp_head: Instead of two separate hashes sp_funs/m_spprocs representing sets of stored routines used by this routine we use one hash - m_sroutines. sp_instr_set_trigger_field: Added support for subqueries in assignments to row accessors in triggers. Removed declaration of sp_add_sp_tables_to_table_list() since now we don't have separate stage on which we add tables used by routines used by statement to table list for prelocking. We do it on the same stage as we load those routines in SP cache. sql/sql_base.cc: open_tables(): - LEX::spfuns/spprocs hashes were replaced with one LEX::sroutines hash. - Now instead of doing one pass through all routines used in statement for caching them and then doing another pass for adding their tables to table list, we do only one pass during which do both things. It is easy to do since all routines in the set of routines used by statement are linked in the list. This also allows us to calculate table list for prelocking more precisely. - Now triggers properly inform prelocking algorithm about tables they use. sql/sql_lex.cc: lex_start(): Replaced LEX::spfuns/spprocs with with one LEX::sroutines hash. Added LEX::sroutines_list list linking all elements in this hash. st_lex::st_lex(): Moved definition of LEX constructor to sql_lex.cc file to be able use sp_sroutine_key declaration from sp.h in it. sql/sql_lex.h: LEX: Replaced two separate hashes for stored routines used by statement with one. Added list linking all elements in this hash to be able to iterate through all elements and add new elements to this hash at the same time. Moved constructor definition to sql_lex.cc. sql/sql_parse.cc: mysql_execute_command(): Replaced LEX::spfuns/spprocs with one LEX::sroutines hash. sql/sql_trigger.cc: Added missing GNU GPL notice. Table_triggers_list::check_n_load() Added initialization of sroutines_key which stores key representing triggers of this table in the set (hash) of routines used by this statement. sql/sql_trigger.h: Added missing GNU GPL notice. Table_triggers_list: Added sroutines_key member to store key representing triggers of this table in the set (hash) of routines used by this statement. Declared sp_cache_routines_and_add_tables_for_triggers() as friend since it needs access to sroutines_key and trigger bodies. sql/sql_yacc.yy: - Now we use sp_add_used_routine() instead of sp_add_to_hash() for adding elements to the set of stored routines used in statement. - Enabled support of subqueries as right sides in assignments to triggers' row accessors.

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). mysql-test/r/trigger.result: Added test which attempts to create trigger for table referencing to field which does not exist in this table. mysql-test/t/trigger.test: Added test which attempts to create trigger for table referencing to field which does not exist in this table. sql/item.cc: Item_trigger_field::setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/item.h: Item_trigger_field: - Added next_trg_field member for linking all such objects in trigger in one list. - Also setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/mysql_priv.h: Added SQL_LIST::push_back() method which allows to add another SQL_LIST to the end of this SQL_LIST. sql/sp_head.cc: sp_head::init()/reset_lex()/restore_lex(): In order to fill global LEX::trg_table_fields (list of all Item_trigger_field objects for trigger) we should init the same list in LEX of substatement before its parsing and merge it to global list after parsing. sql/sp_head.h: sp_instr_trigger_field: Made trigger_field member public to be able to add it more easily to global list of all Item_trigger_field objects in trigger. sql/sql_lex.cc: LEX::trg_table was removed. sql/sql_lex.h: Now we are binding Item_trigger_field's to TABLE object by passing through specially constructed list of all such objects in this trigger instead of doing this during trigger definition parsing at table open. So we no longer need LEX::trg_table, we use LEX::trg_table_fields list instead. sql/sql_parse.cc: mysql_execute_command(): Since now we use trigger body for some checks in mysql_create_or_drop_trigger() we should destroy it only after calling this function. sql/sql_trigger.cc: Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). Table_triggers_list::prepare_old_row_accessors() method was added to be able to reuse code creating Field objects referencing TABLE::record[1] buffer instead of TABLE::record[0]. sql/sql_trigger.h: Added Table_triggers_list::prepare_old_row_accessors() method to be able to reuse code creating Field objects referencing to TABLE::record[1] instead of record[0]. sql/sql_yacc.yy: Now instead of performing binding of Item_trigger_field objects to TABLE object during trigger definition parsing at table open, we perform this binding by passing through specially constructed list of all such items in trigger. We also check value returned from memory allocation functions.

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures.

WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures.

Added st_trg_chistics structure describing properties of trigger being created (as struct and as LEX member). Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added LEX::trg_table which points to table being opened when we are parsing trigger definition while opening table. sql/sql_parse.cc: Added support for CREATE/DROP TRIGGER commands. sql/sql_table.cc: Cleanup. close_cached_table() always returns 0 and its result is not analyzed in most places so chenged its return type to void. sql/sql_update.cc: Added triggers invocation for UPDATE (should be fixed for sure :)) sql/sql_yacc.yy: Added support for CREATE/DROP TRIGGER statements. Added support for OLD/NEW row identifiers in trigger. Made assignment to user variables not to break execution of stored function or trigger. sql/table.h: Added TABLE::triggers member representing triggers for this table.

Fix for bug #5888 "Triggers with nonexistent columns cause packets out of order". (final version) Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger. This allows easily check all references to fields in old/new version of row in trigger during execution of CREATE TRIGGER statement (this is more courtesy for users since we can't check everything anyway). We also report that such reference is bad by returning error from Item_trigger_field::fix_fields() method (instead of setup_field()) This means that if trigger is broken we will bark during trigger execution instead of trigger definition parsing at table open. (i.e. now we allow to open tables with broken triggers). mysql-test/r/trigger.result: Added test which attempts to create trigger for table referencing to field which does not exist in this table. mysql-test/t/trigger.test: Added test which attempts to create trigger for table referencing to field which does not exist in this table. sql/item.cc: Item_trigger_field::setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/item.h: Item_trigger_field: - Added next_trg_field member for linking all such objects in trigger in one list. - Also setup_field() now returns void. If any error will occur we will report it at fix_fields() stage. sql/mysql_priv.h: Added SQL_LIST::push_back() method which allows to add another SQL_LIST to the end of this SQL_LIST. sql/sp_head.cc: sp_head::init()/reset_lex()/restore_lex(): In order to fill global LEX::trg_table_fields (list of all Item_trigger_field objects for trigger) we should init the same list in LEX of substatement before its parsing and merge it to global list after parsing. sql/sp_head.h: sp_instr_trigger_field: Made trigger_field member public to be able to add it more easily to global list of all Item_trigger_field objects in trigger. sql/sql_lex.cc: LEX::trg_table was removed. sql/sql_lex.h: Now we are binding Item_trigger_field's to TABLE object by passing through specially constructed list of all such objects in this trigger instead of doing this during trigger definition parsing at table open. So we no longer need LEX::trg_table, we use LEX::trg_table_fields list instead. sql/sql_parse.cc: mysql_execute_command(): Since now we use trigger body for some checks in mysql_create_or_drop_trigger() we should destroy it only after calling this function. sql/sql_trigger.cc: Now instead of binding Item_trigger_field to TABLE objects during trigger definition parsing at table open, we perform pass through special list of all such objects in trigger.

Fix for bugs: #5860 "Multi-table UPDATE does not activate update triggers" #6812 "Triggers are not activated for INSERT ... SELECT" #8755 "Trigger is not activated by LOAD DATA". This patch also implements proper handling of triggers for special forms of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE. Also now we don't call after trigger in case when we have failed to inserted/update or delete row. Trigger failure should stop statement execution. I have not properly tested handling of errors which happen inside of triggers in this patch, since it is simplier to do this once we will be able to access tables from triggers. mysql-test/r/trigger.result: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". mysql-test/t/trigger.test: Added tests for triggers behavior for various non-standard forms of INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE. Also added tests for bugs #5860 "Multi-table UPDATE does not activate update triggers", #6812 "Triggers are not activated for INSERT ... SELECT" and #8755 "Trigger is not activated by LOAD DATA". sql/item.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field::setup_field()/fix_fields() were changed to implement this approach. sql/item.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Item_trigger_field: - Added field_idx member to store index of Field object corresponding to this Item in TABLE::field array. - Added triggers member to be able to access to parent Table_trigger_list object from fix_fields() method. - setup_field() no longer needs to know for which type of event this trigger is, since it does not make decision Field for which buffer (record[0] or record[1] is appropriate for this Item_trigger_field) sql/mysql_priv.h: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_base.cc: Added fill_record_n_invoke_before_triggers() methods. They are simple wrappers around fill_record() which invoke proper before trigger right after filling record with values. sql/sql_delete.cc: mysql_delete(): Now we stop statement execution if one of triggers failed, we also don't execute after delete trigger if we failed to delete row from the table (We also pass information about which buffer contains old version of row to process_triggers()). multi_delete::send_data()/do_deletes(): Now we also invoke triggers in case of multi-delete. sql/sql_insert.cc: mysql_insert(): Moved invocation of before triggers to fill_record_n_invoke_before_triggers() method. After triggers are now executed as part of write_record(). (as nice side effect now we also stop statement execution if one of triggers fail). write_record(): Invoke after insert trigger after performing insert. Also invoke proper triggers if insert is converted to update or conflicting row is deleted. Cleaned up error handling a bit - no sense to report error via handler::print_error if it was not generated by handler method and was reported before. Also now we will execute after trigger only if we really have written row to the table. select_insert::send_data()/store_values(): We should also execute INSERT triggers for INSERT ... SELECT statement. sql/sql_load.cc: read_fixed_length()/read_sep_field(): We should execute INSERT triggers when processing LOAD DATA statement. Small cleanup in auto-increment related code. Also moved check for thd->killed which is used to abort LOAD DATA in case of problems in 'traditional' mode to better place.. sql/sql_trigger.cc: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances. Now after trigger parsing (in Item_trigger_field::setup_table()) we only find index of proper Field in the TABLE::field array. Then before trigger is invoked we set Table_triggers_list::old_field/new_field so they point to arrays holding Field instances bound to buffers with proper row versions. And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Table_triggers_list methods were changed to implement this approach (see also comments for sql_trigger.h). sql/sql_trigger.h: Since it turned out that at trigger loading time we can't say in which buffer TABLE::record[0] or record[1] old version of row will be stored we have to change our approach to binding of Item_trigger_field to Field instances.

And as last step in Item_trigger_field::fix_fields() we get pointer to Field from those arrays using saved field index. Changed Table_triggers_list to implement this new approach: - Added record1_field member to store array of Field objects bound to TABLE::record[1] buffer (instead of existing old_field member) - Added new_field member and changed meaning of old_field member. During trigger execution they should point to arrays of Field objects bound to buffers holding new and old versions of row respectively. - Added 'table' member to be able to get access to TABLE instance (for which this trigger list object was created) from process_triggers() method. - Now process_triggers() method sets old_field and new_field members properly before executing triggers body (basing on new old_row_is_record1 parameter value). - Renamed prepare_old_row_accessors_method() to prepare_record1_accessors() Also added has_before_update_triggers() method which allows to check whenever any before update triggers exist for table. sql/sql_update.cc: mysql_update(): Now we invoke before triggers in fill_record_n_invoke_before_triggers() method. Also now we abort statement execution when one of triggers fail. safe_update_on_fly(): When we are trying to understand if we can update first table in multi update on the fly we should take into account that BEFORE UPDATE trigger can change field values. multi_update::send_data()/do_updates() We should execute proper triggers when doing multi-update (in both cases when we do it on the fly and using temporary tables).

Added LEX::trg_table which points to table being opened when we are parsing trigger definition while opening table. sql/sql_parse.cc: Added support for CREATE/DROP TRIGGER commands. sql/sql_table.cc: Cleanup. close_cached_table() always returns 0 and its result is not analyzed in most places so chenged its return type to void. sql/sql_update.cc: Added triggers invocation for UPDATE (should be fixed for sure :)) sql/sql_yacc.yy: Added support for CREATE/DROP TRIGGER statements. Added support for OLD/NEW row identifiers in trigger. Made assignment to user variables not to break execution of stored function or trigger. sql/table.h: Added TABLE::triggers member representing triggers for this table.

my_error(ER_WRONG_OBJECT, MYF(0),
table_name, triggers_file_ext, "TRIGGER");
WL#1218 "Triggers". Some very preliminary version of patch. Mostly needed for Monty for him getting notion what needed for triggers from new .FRM format. Things to be done: - Right placement of trigger's invocations - Right handling of errors in triggers (including transaction rollback) - Support for priviliges - Right handling of DROP/RENAME table (hope that it will be handled automatically with merging of .TRG into .FRM file) - Saving/restoring some information critical for trigger creation and replication with their definitions (e.g. sql_mode, creator, ...) - Replication Already has some known bugs so probably not for general review. include/mysqld_error.h: Added trigger related error codes. sql/Makefile.am: Added sql_trigger.* files to list of sources from which mysqld is built. sql/item.cc: Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item.h: Added enums for describing trigger properties. (Here because of dependencies). Added Item_trigger_field class representing field of new/old version of row which is inserted/updated/deleted and for which trigger is invoked. sql/item_func.cc: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. Added comment clarifying why we don't need set no_send_ok when calling stored functions. sql/item_func.h: Added Item_func_set_user_var::print_as_stmt() for printing of assignment to ser variable from stored procedures. sql/lex.h: Symbols used in statements defining triggers were added. sql/mysql_priv.h: Exported some functions needed for triggers implementation. sql/parse_file.cc: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/parse_file.h: Cleaned up FILE_OPTIONS_STRLIST handling (needed for triggers). sql/share/czech/errmsg.txt: Added trigger related error messages. sql/share/danish/errmsg.txt: Added trigger related error messages. sql/share/dutch/errmsg.txt: Added trigger related error messages. sql/share/english/errmsg.txt: Added trigger related error messages. sql/share/estonian/errmsg.txt: Added trigger related error messages. sql/share/french/errmsg.txt: Added trigger related error messages. sql/share/german/errmsg.txt: Added trigger related error messages. sql/share/greek/errmsg.txt: Added trigger related error messages. sql/share/hungarian/errmsg.txt: Added trigger related error messages. sql/share/italian/errmsg.txt: Added trigger related error messages. sql/share/japanese/errmsg.txt: Added trigger related error messages. sql/share/korean/errmsg.txt: Added trigger related error messages. sql/share/norwegian-ny/errmsg.txt: Added trigger related error messages. sql/share/norwegian/errmsg.txt: Added trigger related error messages. sql/share/polish/errmsg.txt: Added trigger related error messages. sql/share/portuguese/errmsg.txt: Added trigger related error messages. sql/share/romanian/errmsg.txt: Added trigger related error messages. sql/share/russian/errmsg.txt: Added trigger related error messages. sql/share/serbian/errmsg.txt: Added trigger related error messages. sql/share/slovak/errmsg.txt: Added trigger related error messages. sql/share/spanish/errmsg.txt: Added trigger related error messages. sql/share/swedish/errmsg.txt: Added trigger related error messages. sql/share/ukrainian/errmsg.txt: Added trigger related error messages. sql/sp_head.cc: sp_head::init_strings(): added support for triggers (we don't have most of strings for them) sp_head::execute_function(): triggers don't require RETURN sp_head::reset_lex(): added propagation of trigger properties to LEX used for parsing of statements composing trigger body. Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sp_head.h: Added new type of sp_head object - TYPE_ENUM_TRIGGER Added two more SP instructions: - sp_instr_set_user_var for setting user variables in stored functions and triggers (we can't use sp_instr_stmt and "SET @a:=..." statement since it will close open tables and thus break execution of calling statement. - sp_instr_set_trigger_field for assignment to fields of row being updated/inserted in triggers sql/sql_base.cc: Now freeing memory occupied by trigger related structures when closing tables. open_unireg_entry(): added loading of triggers for table. find_field_in_real_table() is now public since it required by Item_trigger_field in item.cc sql/sql_delete.cc: Added triggers invocation for DELETE (should be fixed for sure :)) sql/sql_insert.cc: Added triggers invocation for INSERT (should be fixed for sure :)) sql/sql_lex.cc: Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added initialization of LEX->trg_table to lex_start(). (When triggers are parsed during opening of table it points to table object.) sql/sql_lex.h: Added trigger related commands. Added st_trg_chistics structure describing properties of trigger being created (as struct and as LEX member). Added trg_new_row_fake_var variable pointer to which is used for distinguishing between assignment to NEW row field (when parsing trigger definition) and structured variable. Added LEX::trg_table which points to table being opened when we are parsing trigger definition while opening table. sql/sql_parse.cc: Added support for CREATE/DROP TRIGGER commands. sql/sql_table.cc: Cleanup. close_cached_table() always returns 0 and its result is not analyzed in most places so chenged its return type to void. sql/sql_update.cc: Added triggers invocation for UPDATE (should be fixed for sure :)) sql/sql_yacc.yy: Added support for CREATE/DROP TRIGGER statements. Added support for OLD/NEW row identifiers in trigger. Made assignment to user variables not to break execution of stored function or trigger. sql/table.h: Added TABLE::triggers member representing triggers for this table.
