062a1b8b4e a compiler must see '#pragma implementation' *before*
'#pragma interface' (that comes with the #include'd header file)
2005-06-05 19:38:52 +02:00
72dd44b9de Move USE_PRAGMA_IMPLEMENTATION to proper place
Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable


mysql-test/r/func_gconcat.result:
  Move innodb specific test to innodb.test
  Changed table name r2 -> t2
  More test to see how ROLLUP was optimized
mysql-test/r/innodb.result:
  Moved test here form func_gconcat
mysql-test/r/olap.result:
  New test results after optimization
mysql-test/t/func_gconcat.test:

9fcda7fcc5 A fix and test case for Bug#9096 "select doesn't return all matched
records if prepared statements is used".
This fix changes equality evaluation method of basic constants from
by-name to by-value, thus effectively enabling use of parameter markers
in some optimizations (constants propagation, evaluation of possible
keys for query).


mysql-test/r/ps.result:
  Test results for the test case for Bug#9096
mysql-test/t/ps.test:
  A short test case for Bug#9096 "select doesn't return all matched records if
   prepared statements is used". The is enough to reproduce the
  glitch in update_ref_and_keys causing the bug to occur.
sql/item.cc:
  Implement by-value equality evaluation of basic constants.
  This is needed to work with Item_param values. Until now
  Item_param was compared with other items by its name, which is always "?".
  The bug at hand showed up when an integer
  constant was created from one parameter marker (with value 200887 and
   name "?") and then compared by-name with another parameter marker
  (with value 860 and name "?"). True returned by this comparison resulted
  in a wrong table access method used to evaluate the query.
  Implement Item_param methods needed to emulate "basic constant" mode at 
  full.
sql/item.h:
  Change declaration of basic_const_item(): now it also widens its 
  argument from const Item * to Item * if the argument is a basic constant.
  Declare eq() for all basic constatns, as long as now they 
  are compared by value, not by name. Each constant needs its own
  comparison method.
  Declarations of Item_param methods needed to fully emulate 
  a basic constant when parameter value is set.
sql/item_func.cc:
  Fix wrong casts.

e6ce543f05 Fix for Bug #9913 "udf_deinit is not called after execution of PS"
(aka "deinit is not called when calling udf from trigger").

We should call udf_deinit() function during cleanup phase after prepared
(or ordinary) statement execution instead of calling it from Item's
desctructor.

No test case is provided since it is hard to test UDF's from our test
suite.


sql/item_func.cc:
  udf_handler:
   Moved all functionality from udf_handler::~udf_handler() to 
   udf_handler::cleanup() method which will be called after
   each PS execution, thus allowing udf_deinit() to be executed
   symetrically with udf_init() (which is executed for each
   execution of PS).
  Added Item_udf_func::cleanup() which performs proper cleanup after
  execution of PS with UDF function.
sql/item_func.h:
  Added Item_udf_func::cleanup() method to perform cleanup properly after
  execution of PS with UDF function.
sql/item_sum.cc:
  Added Item_udf_sum::cleanup() method to perform cleanup properly after
  execution of PS with aggregate UDF function.
sql/item_sum.h:
  Added Item_udf_sum::cleanup() method to perform cleanup properly after
  execution of PS with aggregate UDF function.
sql/sql_udf.h:
  Added udf_handler::cleanup() method declaration which is responsible
  for cleaning up UDF execution context at the end of execution of
  statement (using ~udf_handler() for this purprose did not worked for PS).

  After discussion with PeterG and Serge, a new coercibility
  level for "system constants" was introduced, between
  COERRIBLE and IMPLICIT. Thus:
  SELECT col1 = USER() FROM t1; - is done according to col1 collation.
  SELECT 'string' = USER(); - is done according to USER() collation.
  At the same time, "nagg" and "strong" members were removed as unused.

2fb807d1d0 A user variable are now always have IMPLICIT coercibility,
independently from the expression it is initialized from.
In other words, this change treats a user variable like
a table with one column and one record. Discussed with 
PeterG, Serg and Lars. This change also simplifies replication
allowing not to replicate variables' coercibility.

435b20aa68 Simpler arena swapping code
Now thd->mem_root is a pointer to thd->main_mem_root and THR_MALLOC is a pointer to thd->mem_root.
This gives us the following benefits:
- Allow us to easily detect if arena has already been swapped before (this fixes a bug in setup_conds() where arena was swaped twice in some cases)
- Faster swaps of arenas (as we don't have to copy the whole MEM_ROOT)
- We don't anymore have to call my_pthread_setspecific_ptr(THR_MALLOC,...) to change where memory is alloced. Now it's enough to set thd->mem_root

aee1e78aa1 As it is wrong and confusing to associate any
character set with NULL, @a should be latin2
after this query sequence:

   SET @a=_latin2'string';
   SET @a=NULL;

I.e. the second query should not change the charset
to the current default value, but should keep the
original value assigned during the first query.
In order to do it, we don't copy charset
from the argument if the argument is NULL
and the variable has previously been initialized.

statements and replication is on (as well as several similar issues).
Until now we did not reset THD before every execution of a prepared
statement, so if some execution had set thd->time_zone_used
or thd->rand_used they would not be reset until next mysql_parse.
Some of post-review fixes done.

  to lex_start.
sql/sql_lex.h:
  All lex-related initialization is now in lex_start.
  Move thd->select_number to lex->select_number to be able to use it
  easily in lex_start.
sql/sql_parse.cc:
  Split mysql_init_query into two functions: mysql_reset_thd_for_next_query,
  which is used in PS and conventional execution, and lex_start, used only
  when we want to parse something.
  Fix init_connect to use initialized THD.
sql/sql_prepare.cc:
  Deploy mysql_reset_thd_for_next_query to reset THD state before
  execution of a prepared statement.
  Normally this should have been added to just one place, but
  we have to reset thd before assigning placeholders from variables,
  thus we can't do that in execute_stmt (yuck).
