Crash happened when one selected data from one of INFORMATION_SCHEMA
tables and in order to build its contents server had to open view which
used stored function and table or view on which one had not global or
database-level privileges (e.g. had only table-level or had no
privileges at all).
The crash was caused by usage of check_grant() function, which assumes
that either number of tables to be inspected by it is limited explicitly
or table list used and thd->lex->query_tables_own_last value correspond
to each other (the latter should be either 0 or point to next_global
member of one of elements of this table list), in conditions when
above assumptions were not true. This fix just explicitly limits
number of tables to be inspected. Other negative effects which are
caused by the fact that thd->lex->query_tables_own_last might not
be set properly during processing of I_S tables are less disastrous
and will be reported and fixed separetely.
There are two main idea of this fix:
- introduce a common function for server and client to split user value
(<user name>@<host name>) into user name and host name parts;
- dump DEFINER clause in correct format in mysqldump.
Bug#14387 SHOW COLUMNS doesn't work on temporary tables.
Bug#15224 SHOW INDEX from temporary table doesn't work.
Restore thd->temporary_tables to be able to process
temporary tables(only for 'show index' & 'show columns').
This should be changed when processing of temporary tables for
I_S tables will be done.
Bad examples of usage of a string with its length fixed.
The incorrect length in the trigger file configuration descriptor
fixed (BUG#14090).
A hook for unknown keys added to the parser to support old .TRG files.
- CHAR() now returns binary string as default
- CHAR(X*65536+Y*256+Z) is now equal to CHAR(X,Y,Z) independent of the character set for CHAR()
- Test for both ETIMEDOUT and ETIME from pthread_cond_timedwait()
(Some old systems returns ETIME and it's safer to test for both values
than to try to write a wrapper for each old system)
- Fixed new introduced bug in NOT BETWEEN X and X
- Ensure we call commit_by_xid or rollback_by_xid for all engines, even if one engine has failed
- Use octet2hex() for all conversion of string to hex
- Simplify and optimize code
- Added show status variable "compression" for checking that compression is turned on.
- Updated show status variable "have_openssl" to be set to DISABLED if server supports ssl but it's not turned on to accept incoming ssl connections.
- Setup server to accept ssl connections from clients ig that is supported by server
- New tests
- ssl - Run with ssl turned on
- ssl_compress - Run with ssl and compression turned on
- compress - Run with compression turned in
- Updated test
- openssl_1, rpl_openssl1 - Changed to run if server supports ssl
After SHOW TABLE STATUS last_insert_id wasn't cleaned, and next select
erroneously rewrites WHERE condition and returs a row;
5.0 isn't affected because of different SHOW TABLE STATUS handling.
last_insert_id cleanup added to mysqld_extend_show_tables().
Handlerton array is now created instead of using sys_table_types_st. All storage engines can now have inits and giant ifdef's are now gone for startup. No compeltely clean yet, handlertons will next be merged with sys_table_types. Federated and archive now have real cleanup if their inits fail.
"CHARACTER SET", "COLLATE", and "DEFAULT" are always
printed(excepting MODE_MYSQL323 and MODE_MYSQL40)
"AUTO_INCREMENT", "ON UPDATE CURRENT_TIMESTAMP" are printed only
if NO_FIELD_OPTIONS is not set.
problems which were introduced during work on WL#2787 "Add view definer/owner
to the view definition (.frm) to check privileges on used tables and stored
routines when using a VIEW."
In some cases it is better to use value from Security_context::host_or_ip
instead of value from Security_context::host since the latter can be NULL
in certain situations (When we can't resolve hostname or we have not done
this yet).
