Fixed valgrind complaints. This fixes the memory leak problems for
procedured, and partially for functions. There's still a leak involving
results from functions that turned out to be too involved, so it will be
fixed separately.
We should not allow explicit or implicit transaction commits inside
of stored functions or triggers (so in autocommit mode we should not
do commits after execution of sub-statement).
Also since we don't support nested statement transactions in 5.0,
we shouldn't commit or rollback stmt transactions while we are inside
stored functions or triggers. This should be fixed in later (>=5.1)
releases.
Simple optimization for 2 argument usage to function of variable arguments
Fix stack overrun when using 1+1+1+1+1+1+1+....
Update crash-me results for 5.0
Don't call post_open if pre_open() fails (optimization)
Ensure that 'null_value' is not accessed before val() is called in FIELD() functions
Fixed initialization of key maps. This fixes some problems with keys when you have more than 64 keys
Fixed that ROLLUP don't always create a temporary table. This fix ensures that func_gconcat.test results are now predictable
Fixed bug #9939: a wrong conversion of arguments
for functions COALESCE and IFNULL.
The str_op virtual method was added into Item_func_numhybrid.
item_func.cc:
Fixed bug #9939: a wrong conversion of arguments
for functions COALESCE and IFNULL.
The str_op virtual method was added into Item_func_numhybrid.
item_cmpfunc.h, item_cmpfunc.cc:
Fixed bug #9939: a wrong conversion of arguments
for functions COALESCE and IFNULL.
Item_func_coalesce and Item_func_ifnull now
inherit from a modified Item_func_numhybrid.
case.test, case.result:
Added test cases for bug #9939.
set_var.cc:
variables.result
variables.test
Bug #10904 Illegal mix of collations between a system variable and a constant
Changing coercibility of system variables to SYSCONST,
to be the same with USER(), DATABASE(), etc.
This only showed up on two known platforms, both ia64 (one HP-UX and one Linux wich icc).
For some reason, they only get half the stack size they are supposed to have, which
makes deep SP recursion overrun the stack before check_stack_overrun() is triggered.
Also made som minor fixes in the check_stack_overrun() definition, supporting variable
margins.
No test case added, but the reason for the bug report was a failed existing test case
on these machines, which now works.
