756223bbda WL#1622 "SQL Syntax for Prepared Statements": post-review fixes:
Moved PS name to Statement class, Statement_map now handles name-to-statement resolution.
  Both named and unnamed statements are now executed in one function (sql_prepare.cc:execute_stmt)
  Fixed a problem: Malformed sequence of commands from client could cause server to use previously deleted objects.
  Some code cleanup and small fixes

bc5365b4bb Stubs for types/names of placeholders, cursor flags and array execution count
implemented in the client library and server.
Warning: this makes the new client library and server incompatible with all 
previous versions and 5.0.


libmysql/libmysql.c:
  Make client library compatible with future extensions: types of placeholders, 
   names of named parameters, cursors and array execution.
sql/sql_prepare.cc:
  Alpha server side support for future extensions: types of placeholders and names of
  named parameters are sent to client (virtually), cursor flags and execution
  count received in COM_EXECUTE packet are ignored.

ef44fb9af3 Fixes for bugs #2274 "mysqld gets SIGSEGV during processing of malformed
COM_EXECUTE packet" and #2795 "prepare + execute without bind_param crashes
 server" and #2473 "seg fault running tests/client_test.c": 
- length checking added to packet parser 
- default impelemntation of Item_param::set_param_func will work in
case of malformed packet.
No test cases are possible in our test suite, as there are no tests 
operating on protocol layer.


sql/item.cc:
  Default set_param function implemented: this is to not sigsegv in case
  of malformed packet with no parameters data.
sql/item.h:
  - Item_param constructor moved to .cc to be able to assign set_param_func.
  - now embedded and ordinary versions of set_param have the same signature.
sql/mysql_priv.h:
  mysql_stmt_execute now requires packet_length
sql/sql_parse.cc:
  mysql_stmt_execute now requires packet length.
sql/sql_prepare.cc:
  - length checking added to all functions working with network packet.
  - set_param_func's in embedded and ordinary version now have the same 
  signature

7b68eaafda Desperate attempt to push part of prepared statements cleanup which was
reviewed in Saint-Petersbourg (including post-review fixes).


include/my_sys.h:
  Added clear_alloc_root (reset alloc root without freeing its memory)
sql/item.h:
  - rename setup_param -> set_parap (function assigns parameter value to item)
sql/mysql_priv.h:
  - all return values are void, because return value is never checked in
      dispatch_command
  - removed unused declaration of setup_param_functions
sql/protocol.h:
  - unused declarations of setup_params_data* removed
sql/sql_class.cc:
  Cleanup:
    - bzero(mem_root) replaced with clear_alloc_root
    - query_id and command members moved back to THD from Statement
  Assignment of mem_root, free_list, query_id and command optimized
  away from set_statement().
sql/sql_class.h:
  - query_id and command moved back to THD from Statement
sql/sql_lex.h:
  - better type for param_list
  - param_count is the same thing as param_list.elements
sql/sql_parse.cc:
  - comments for dispatch_command
sql/sql_prepare.cc:
  Cleanup:
  - added comments to many functions and removed trailing spaces in many 
    lines, some stale comments removed.
  - it's faster to iterate using pointers, than classes
  - Renames: error_in_prepare renamed to get_longdata_error (because it is set
    when there is an error in mysql_send_longdata, rather than in
    mysql_prepare), embedded versions of placeholder assignement functions
    now have prefix emb_, setup_ functions renamed to set_, because they
    perform assignment, not installation, setup_params_data now doesn't
    call insert_params and was renamed to setup_set_param_functions,
  - find_prepared_statement should not send error if called from no-reply
    calls, like mysql_stmt_reset
  - error reporting is checked up, to always report errors and not report
    errors twice. send_prep_stmt can be done mostly in send_prepare_result, 
    rather than in test_* functions.
  - now we don't need to reinit THD->mem_root/free_list in mysql_stmt_execute,
    because it's not reset there.
tests/client_test.c:
  - removed second call to test_subqueries

0aa48dc500 Fix for BUG#2703
"MySQL server does not detect if garbage chars at the end of query":

Detect garbage chars at the end of the query or at the end of a query
for a prepared statement (which happens if mysql_real_query() or mysql_prepare()
were called with a too big 'length' parameter (bigger than the real intended
length of the query: then we receive a query + garbage characters from the
client). This resulted in garbage chars written into the binlog.
Now instead the client receives something like:
'You have an error in your SQL syntax.  Check the manual that corresponds
to your MySQL server version for the right syntax to use near '!stmt'
at line 1' i.e. the server is pointing at the weird tail of the query
(this '!stmt' are the garbage chars sent by the client).
All tests pass, except mysqldump.test and ctype_utf8.test but they failed
before the patch.


sql/sql_parse.cc:
  Detect garbage chars at the end of the query
  (which happens if mysql_real_query() was called with a too big 'length'
  parameter (bigger than the real intended length of the query: then
  we receive a query + garbage characters from the client).
sql/sql_prepare.cc:
  Detect garbage chars at the end of the query
  (which happens if mysql_prepare() was called with a too big 'length'
  parameter (bigger than the real intended length of the query: then
  we receive a query + garbage characters from the client).
tests/client_test.c:
  The change to sql_parse.cc and sql_prepare.cc rightfully gives many
  syntax errors to tests/client_test.c which is full of
  mysql_prepare(mysql, "SHOW TABLES", 100).
  Correcting all these commands.
