52ac4935e7 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:

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.

eaf34dd8e3 Port of cursors to be pushed into 5.0 tree:
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.


include/mysql.h:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - new statement attribute STMT_ATTR_CURSOR_TYPE
  - MYSQL_STMT::flags to store statement cursor type
  - MYSQL_STMT::server_status to store server status (i. e. if the server
  was able to open a cursor for this query).
include/mysql_com.h:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - new COMmand, COM_FETCH, to fetch K rows from read-only cursor.
    By design should support scrollable cursors as well.
  - a few new server statuses:
    SERVER_STATUS_CURSOR_EXISTS is sent by server in reply to COM_EXECUTE,
    when cursor was successfully opened for this query
    SERVER_STATUS_LAST_ROW_SENT is sent along with the last row to prevent one
    more round trip just for finding out that all rows were fetched from 
    this cursor (this is server mem savier also).
  - and finally, all possible values of STMT_ATTR_CURSOR_TYPE, 
    while now we support only CURSORT_TYPE_NO_CURSOR and 
    CURSOR_TYPE_READ_ONLY
libmysql/libmysql.c:
  Cursor patch to push into the main tree, client library part (considered 
  stable):
  - simple additions to mysql_stmt_fetch implementation to read data 
    from an opened cursor: we can read up to iteration count rows per
    one request; read rows are buffered in the same way as rows of
    mysql_stmt_store_result.
  - now send stmt->flags to server to let him now if we wish to have 
    a cursor for this statement.
  - support for setting/getting statement cursor type.
libmysqld/examples/Makefile.am:
  Testing cursors was originally implemented in C++. Now when these tests
  go into client_test, it's time to convert it to C++ as well.
libmysqld/lib_sql.cc:
  - cleanup: send_fields flags are now named.
sql/ha_innodb.cc:
  - cleanup: send_fields flags are now named.
sql/mysql_priv.h:
  - cursors support: declaration for server-side handler of COM_FETCH
sql/protocol.cc:
  - cleanup: send_fields flags are now named.
  - we can't anymore assert that field_types[field_pos] is sensible:
    if we have COM_EXCUTE(stmt1), COM_EXECUTE(stmt2), COM_FETCH(stmt1)
    field_types[field_pos] will point to fields of stmt2.
sql/protocol.h:
  - cleanup: send_fields flag_s_ are now named.

sql/sql_handler.cc:
  - cleanup: send_fields flags are now named.
sql/sql_help.cc:
  - cleanup: send_fields flags are now named.
sql/sql_parse.cc:
  Server side support for cursors:
  - handle COM_FETCH
  - enforce assumption that whenever we free thd->free_list, 
    we reset it to zero. This way it's much easier to handle free_list
    in prepared statements implementation.
sql/sql_prepare.cc:
  Server side support for cursors:
  - implementation of mysql_stmt_fetch (fetch some rows from open cursor).
  - management of cursors memory is quite tricky now.
  - execute_stmt can't be reused anymore in mysql_stmt_execute and 
    mysql_sql_stmt_execute
sql/sql_repl.cc:
  - cleanup: send_fields flags are now named.
sql/sql_select.cc:
  Server side support for cursors:
  - implementation of Cursor::open, Cursor::fetch (buggy when it comes to
    non-equi joins), cursor cleanups.
  - -4 -3 -0 constants indicating return value of sub_select and end_send are
    to be renamed to something more readable:
    it turned out to be not so simple, so it should come with the other patch.
sql/sql_select.h:
  Server side support for cursors:
  - declaration of Cursor class.
  - JOIN::fetch_limit contains runtime value of rows fetched via cursor.
sql/sql_show.cc:
  - cleanup: send_fields flags are now named.
sql/sql_table.cc:
  - cleanup: send_fields flags are now named.
sql/sql_union.cc:
  - if there was a cursor, don't cleanup unit: we'll need it to fetch
    the rest of the rows.
tests/Makefile.am:
  Now client_test is in C++.
tests/client_test.cc:
  A few elementary tests for cursors.
BitKeeper/etc/ignore:
  Added libmysqld/examples/client_test.cc to the ignore list
2004-08-03 03:32:21 -07:00
konstantin@mysql.com
d3e520ce7e Port of cursors to be pushed into 5.0 tree:
- client side part is simple and may be considered stable
- server side part now just joggles with THD state to save execution
  state and has no additional locking wisdom.
  Lot's of it are to be rewritten.
