revno: 2617.31.26
committer: Alexander Nozdrin <alik@sun.com>
branch nick: 6.0-rt-bug43138.3
timestamp: Thu 2009-04-30 19:31:30 +0400
message:
  Fix for Bug#43138: DROP DATABASE failure does not clean up message list.
  
  The problem was that the high-level function mysql_rm_db() invoked
  low-level mysql_rm_table_part2(), which reported low-level error
  (Unknown table) if SE refused to delete a table. Also when
  mysql_rm_table_part2() reported an error, it didn't add corresponding
  warning into the list (because it is used from other places where such
  behaviour is required).
  
  The fix is to
    1. Remove no_warnings_for_error usage from sql_table.cc
    2. Improve internal error handler support in THD, so that
       a stack of error handlers is allowed.
    3. Create an internal error handler (Drop_table_error_handler)
       to silence useless warnings.
    4. Use the handler in DROP DATABASE and DROP TABLE statements.

  Fixed drop.test failure under non-debug server by moving part
  of test dependent on debug-only feature to separate .test file,
  which won't be run for non-debug versions of server.

branch nick: 6.0-rt-bug38347
timestamp: Thu 2009-03-26 09:08:24 +0300
message:
  Patch for Bug#38347: ALTER ROUTINE privilege allows SHOW CREATE TABLE.
  
  If a user has any of the following privileges for a table (or the database
  if the table), he should be able to issue SHOW CREATE TABLE for the table:
    - CREATE
    - DROP
    - ALTER
    - DELETE
    - INDEX
    - INSERT
    - SELECT
    - UPDATE
    - TRIGGER
    - REFERENCES
    - GRANT OPTION
    - CREATE VIEW
    - SHOW VIEW
  
  Any other privilege (even SUPER) should not allow SHOW CREATE TABLE.

timestamp: Fri 2009-03-27 21:36:34 +0300
message:
  Additional patch for Bug#38347 (ALTER ROUTINE privilege
  allows SHOW CREATE TABLE).
  
  The problem was that information_schema.test,
  information_schema_parameters.test and information_schema_routines.test
  failed with the first patch. That happened due to limitation in check_access():
  it allows only SELECT_ACL privilege for INFORMATION_SCHEMA tables.
  
  The patch is to request only SELECT_ACL privilege for INFORMATION_SCHEMA tables.

instead of making it experimental.

2630.29.28, 2630.31.1, 2630.28.13, 2630.28.10, 2617.23.14 and
some other minor revisions.

This patch implements: 

WL#4264 "Backup: Stabilize Service Interface" -- all the
server prerequisites except si_objects.{h,cc} themselves (they can
be just copied over, when needed).

WL#4435: Support OUT-parameters in prepared statements.

(and all issues in the initial patches for these two
tasks, that were discovered in pushbuild and during testing).

Bug#39519: mysql_stmt_close() should flush all data
associated with the statement.

After execution of a prepared statement, send OUT parameters of the invoked
stored procedure, if any, to the client.

When using the binary protocol, send the parameters in an additional result
set over the wire.  When using the text protocol, assign out parameters to
the user variables from the CALL(@var1, @var2, ...) specification.

The following refactoring has been made:
  - Protocol::send_fields() was renamed to Protocol::send_result_set_metadata();
  - A new Protocol::send_result_set_row() was introduced to incapsulate
    common functionality for sending row data.
  - Signature of Protocol::prepare_for_send() was changed: this operation
    does not need a list of items, the number of items is fully sufficient.

The following backward incompatible changes have been made:
  - CLIENT_MULTI_RESULTS is now enabled by default in the client;
  - CLIENT_PS_MULTI_RESUTLS is now enabled by default in the client.
