      BUG#30590 - delete from memory table with composite btree primary key · cf5762b4
      unknown authored
      DELETE query against memory table with btree index may remove
      not all matching rows. This happens only when DELETE uses
      index read method to find matching rows. E.g. for queries
      like DELETE FROM t1 WHERE a=1.
      
      Fixed by reverting fix for BUG9719 and applying proper solution.
      
      
      heap/hp_delete.c:
        Reverted fix for BUG9719 as it makes queries like
        DELETE FROM t1 WHERE a=1 to remove not all matching
        rows (assuming this is memory table and there is btree
        key over `a`).
        
        This happens because we calculate info->lastkey_len in
        heap_rkey(). When we enter heap_rnext(), info->lastkey_len
        is 0 (set by hp_rb_delete_key()). We need to preserve
        info->lastkey_len in this situation, otherwise
        tree_search_key() will always return smallest value in
        a tree.
      heap/hp_rfirst.c:
        If we're performing index_first on a table that was taken from
        table cache, info->lastkey_len is initialized to previous query.
        Thus we set info->lastkey_len to proper value for subsequent
        heap_rnext() calls.
        This is needed for DELETE queries only, otherwise this variable is
        not used.
        Note that the same workaround may be needed for heap_rlast(), but
        for now heap_rlast() is never used for DELETE queries.
      heap/hp_rnext.c:
        An optimization for DELETE queries that use index_first()/index_next().
        Use faster tree_search_edge() instead of tree_search_key().
      mysql-test/r/heap_btree.result:
        A test case for BUG#30590.
      mysql-test/t/heap_btree.test:
        A test case for BUG#30590.

      Cleanup in the "netware" subdirectory: · 870958d2
      unknown authored
      1) We do not provide the "isam" table handler in 5.0 and up (different from "myisam" !),
         so we do not need the ".def" files for the "isam"-specific tools.
      
      2) Use "basename" to get the base name of a file, not a harder-to-read sed expression.
      
      
      BitKeeper/deleted/.del-isamchk.def:
        Delete: netware/isamchk.def
      BitKeeper/deleted/.del-isamlog.def:
        Delete: netware/isamlog.def
      BitKeeper/deleted/.del-pack_isam.def:
        Delete: netware/pack_isam.def
      netware/Makefile.am:
        Use a plain "basename" showing the purpose, not a sed command which is harder to read.

      Fixed bug #30201. · 891b1659
      unknown authored
      Killing a SELECT query with KILL QUERY or KILL CONNECTION
      causes a server crash if the query cache is enabled.
      
      Normal evaluation of a query may be interrupted by the
      KILL QUERY/CONNECTION statement, in this case the mysql_execute_command
      function returns TRUE, and the thd->killed flag has true value.
      In this case the result of the query may
      be cached incompletely (omitting call to query_cache_insert inside
      the net_real_write function), and next call to query_cache_end_of_result
      may lead to server crash.
      Thus, the query_cache_end_of_result function has been modified to abort
      query cache in the case of killed thread.
      
      
      
      sql/sql_cache.cc:
        Fixed bug #30201.
        The  query_cache_end_of_result function has been modified to abort query
        cache in the case of query execution failure. Also this function has been
        modified to remove incomplete query block.

      Fixed bug #30287. · 7c3d5bc5
      unknown authored
      The server created temporary tables for filesort in the working directory
      instead of the specified tmpdir directory.
      
      
      sql/item.cc:
        Fixed bug #30287.
        The Item_field::set_field method has been modified to reset the any_privileges
        flag to false in case of system temporary table. This modification prevents the
        server from unnecessary checking of user privileges to access system temporary
        tables.
      sql/sql_select.cc:
        Fixed bug #30287.
        Bugfix for #29015 has been removed: TABLE_SHARE::table_name of system
        temporary tables contains full path to table file basename again.
      sql/sql_view.cc:
        Fixed bug #30287.
        Commentary has been added.

      Bug #30269 Query cache eats memory · bd80048f
      unknown authored
      Although the query cache doesn't support retrieval of statements containing
      column level access control, it was still possible to cache such statements
      thus wasting memory.
      
      This patch extends the access control check on the target tables to avoid
      caching a statement with column level restrictions. 
      
      
      mysql-test/r/query_cache.result:
        Added test
      mysql-test/t/query_cache.test:
        Added test
      sql/sql_cache.cc:
        The function check_table_access leaves the artifact
        grant.want_privileges= 1, if a statement refers to tables with column level
        privileges. To avoid the statement from being stored into the query cache,
        it is enough to check this flag and set 'safe_to_cache_query' to zero.
      sql/sql_cache.h:
        - Removed 'static' attribute or class methods
        - Added THD parameter to process_and_count_tables
