if inner routine has more local variables than outer one, and
one of its last variables was used as argument to NOT operator".
THD::spcont was non-0 when we were parsing stored routine/trigger
definition during execution of another stored routine. This confused
methods of Item_splocal and forced them use wrong runtime context.
Fix ensures that we always have THD::spcont equal to zero during
routine/trigger body parsing. This also allows to avoid problems
with errors which occur during parsing and SQL exception handlers.
in the function body
Changed the way the end of query was found from the lex state.
The routine body was not extracted correctly when using the
/*!version ... */ wrapper (in dump files); for some types of routines
(e.g. with a label at the first begin), the trailing "*/" was not skipped.
initialization crashes server.
Make sure variables are initialized to something (like null) when
the default initialization fails and a continue handler is in effect.
The problem was to continue at the right place in the code after the
test expression in a flow control statement fails with an exception
(internally, the test in sp_instr_jump_if_not), and the exception is
caught by a continue handler. Execution must then be resumed after the
the entire flow control statement (END IF, END WHILE, etc).
large table gives server crash": make sure that when a MyISAM temporary
table is created for a cursor, it's created in its memory root,
not the memory root of the current query.
procedure
For some functions returning strings (like "replace" and "ifnull" - where
val_str() is returning a pointer into one of the parameters) - we ended
up with a dangling pointer after the new operator destroyed the reuse item
in the eval function.
A working, if not very elegant, solution is to simply copy the string in
such cases.
new file
mysql_fix_privilege_tables.sql, mysql_create_system_tables.sh:
Adding true BINARY/VARBINARY: fixing "password" type, not to be 0x00-padding.
Many files:
Adding true BINARY/VARBINARY: fixing tests not to output 0x00 bytes.
Adding true BINARY/VARBINARY: new pad_char structure member.
ctype-bin.c:
Adding true BINARY/VARBINARY: new pad_char structure member.
New strnxfrm, with two trailing length bytes.
field.cc:
Adding true BINARY/VARBINARY.
procedure variable
Second version, after review.
Keep the unsigned_flag in Item_decimal updated. Note that this also changed
the result of several old test results - creating tables from decimal
templates now gives unsigned columns and different sizes. (Several tests
had Length > Max_length before.)
Search the chain of sp_rcontexts recursively for handlers. If one is found,
it will be detected in the sp_head::execute() method at the corresponding
level.
Replaced the dumb in-handler/not-in-handler check with a proper recursion
check of handlers being executed.
(Re-commit in a different tree, to make push possible.)
Execution rigths on function was checked just before function execution,
thus it was unknown on prepare stage whether user have right to execute
particular function.
Added access rights checking function which is called right after fixing
Item_func_sp.
This have additional effect that if user don't have rights for execution
query will fail on earlier stage and will not waste resources on optimizing
with failing on execution stage.
get strange result
according to Monty's suggestions, fixing the SELECT behaviour on errors
with SP handlers. Note that some warnings from SELECT still shows up when
the handler has caught - this is an effect of another known bug (BUG#7049).
* Allocate thd->user_var_events elements on appropriate mem_root
* If several SP statements are binlogged as a single statement, collect all user var
accesses they make (grep for StoredRoutinesBinlogging for details)
