Bug#49646 mysql --show-warnings crashes when server dies
The problem is that the server could crash when attempting
to access a non-conformant proc system table. One such case
was a crash when invoking stored procedure related statements
on a 5.1 server with a proc system table in the 5.0 format.
The solution is to validate the proc system table format
before attempts to access it are made. If the table is not
in the format that the server expects, a message is written
to the error log and the statement that caused the table to
be accessed fails.

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.

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.
------------------------------------------------------------
The flag EXTRA_ACL is used in conjugation with our access checks, yet it is
not clear what impact this flag has.
This is a code clean up which replaces use of EXTRA_ACL with an explicit
function parameter.
The patch also fixes privilege checks for:
- SHOW CREATE TABLE: The new privilege requirement is any privilege on
the table-level.
- CHECKSUM TABLE: Requires SELECT on the table level.
- SHOW CREATE VIEW: Requires SHOW_VIEW and SELECT on the table level
(just as the manual claims)
- SHOW INDEX: Requires any privilege on any column combination.

MySQL crashes if a user without proper privileges attempts to create a procedure.
The crash happens because more than one error state is pushed onto the Diagnostic
area. In this particular case the user is denied to implicitly create a new user
account with the implicitly granted privileges ALTER- and EXECUTE ROUTINE.
The new account is needed if the original user account contained a host mask.
A user account with a host mask is a distinct user account in this context.
An alternative would be to first get the most permissive user account which
include the current user connection and then assign privileges to that
account. This behavior change is considered out of scope for this bug patch.
The implicit assignment of privileges when a user creates a stored routine is a
considered to be a feature for user convenience and as such it is not
a critical operation. Any failure to complete this operation is thus considered
non-fatal (an error becomes a warning).
The patch back ports a stack implementation of the internal error handler interface.
This enables the use of multiple error handlers so that it is possible to intercept
and cancel errors thrown by lower layers. This is needed as a error handler already
is used in the call stack emitting the errors which needs to be converted.
The bool data type was redefined to BOOL (4 bytes on windows).
Removed the #define and fixed some of the warnings that were uncovered
by this.
Note that the fix also disables 2 warnings :
4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning)
4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation
These warnings will be handled in a separate bug, as they are performance related or bogus.
Fixed to int the return type of functions that return more than
2 distinct values.
When expanding a * in a USING/NATURAL join the check for table access
for both tables in the join was done using the grant information of the
first one.
Fixed by getting the grant information for the current table while
iterating through the columns of the join.

- Fix comments about mysql_create_system_tables.sh
- Use mysql_install_db.sh to create system tables for mysql_test-run-shell

Concurrent read and update of privilege structures (like simultaneous
run of SHOW GRANTS and ADD USER) could result in server crash.
Ensure that proper locking of ACL structures is done.
No test case is provided because this bug can't be reproduced

- fix for bug#16423 (Events: SHOW CREATE EVENT doesn't work)
- this Changeset commits makes CREATE/UPDATE/DELETE EVENT real DDL statements
by committing the currently open transaction before they are executed.
- this Changeset also fixes a trailing space problem since the very early days
of the internal cron
- adds sophisticated checking of whether mysql.event was tampered accidentally
or with purpose by an user.
- adds a lot of inline function documentation - documents everything left
uncodumented
- INTERVAL_XXXX to XXX in I_S.EVENTS.INTERVAL_FIELD
WL#1034 (Internal CRON)
Implement table-level TRIGGER privilege to control access to triggers.
Before this path global SUPER privilege was used for this purpose, that
was the big security problem.
In details, before this patch SUPER privilege was required:
- for the user at CREATE TRIGGER time to create a new trigger;
- for the user at DROP TRIGGER time to drop the existing trigger;
- for the definer at trigger activation time to execute the trigger (if the
definer loses SUPER privilege, all its triggers become unavailable);
This patch changes the behaviour in the following way:
- TRIGGER privilege on the subject table for trigger is required:
- for the user at CREATE TRIGGER time to create a new trigger;
- for the user at DROP TRIGGER time to drop the existing trigger;
- for the definer at trigger activation time to execute the trigger
(if the definer loses TRIGGER privilege on the subject table, all its
triggers on this table become unavailable).
- SUPER privilege is still required:
- for the user at CREATE TRIGGER time to explicitly set the trigger
definer to the user other than CURRENT_USER().
When the server works with database of the previous version (w/o TRIGGER
privilege), or if the database is being upgraded from the previous versions,
TRIGGER privilege is granted to whose users, who have CREATE privilege.
- fix EVENT_ACL problem that GRANT ALL on some_db.* to someone@somewhere did not get to mysql.db
- fix crash when the following is executed :
CREATE EVENT P() CREATE EVENT E ON SCHEDULER 1 SECOND DO ROLLBACK;
(creation works as well as calling P() which creates the event).
- split into several files
- forbid parallel execution (before analyse is done how to make it possible)
because the same sp_head instance cannot be executed in parallel
- added GPL headers
- changed EVENT_ACL to be per DB variable
- fixed minor problems
Post-review fixes that simplify the way access rights
are checked during name resolution and factor out all
entry points to check access rights into one single
function.
multi-threaded environment".
To avoid deadlocks between several simultaneously run account management
commands (particularly between FLUSH PRIVILEGES/SET PASSWORD and GRANT
commands) we should always take table and internal locks during their
execution in the same order. In other words we should first open and lock
privilege tables and only then obtain acl_cache::lock/LOCK_grant locks.
