table' lockup".
Changes from the innodb-5.0-ss92 snapshot.
Do not call os_file_create_tmpfile() at runtime. Instead, create
all tempfiles at startup and guard access to them with mutexes.
Removed include/Makefile.am and the reference to it.
Deleted db/db0err.h and db directory.
Check index column sizes in a better way (bug 13315).
Fixed comments for memory allocation functions and added
some extra checks. Adapted callers.
Fix for bug#12429: Replication tests fail: "Slave_IO_Running" differs:
The value is not important, and it depends on timing. Mask it.
Backport and extension of a fix made by Matthias in 5.0, originally it was

cmp_item_sort_string::cmp() wasn't checking values_res variable for null.
Later called function was dereferenced it and crashed server.
Added null check to cmp_item_sort_string::cmp().
to Crash": the bug was that due to non-standard name
resolution precedence in stored procedures (See Bug#5967)
a stored procedure variable took precedence over a table column
when the arguments for VALUES() function were resolved.
The implementation of VALUES() function was not designed to work
with Item_splocal and crashed.
VALUES() function is non-standard. It can refer to, and
is meaningful for, table columns only. The patch disables SP
variables as possible arguments of VALUES() function.
- Set max_length of Item_func_uuid to max_length*system_charset_info->mbmaxlen
Note! Item_func_uuid should be set to use 'ascii' charset when hex(), format(), md5()
etc will use 'ascii'
- Comitting again, the old patch seems to have been lost.
according to the standard.
The idea is to use Field-classes to implement stored routines
variables. Also, we should provide facade to Item-hierarchy
by Item_field class (it is necessary, since SRVs take part
in expressions).
The patch fixes the following bugs:
- BUG#8702: Stored Procedures: No Error/Warning shown for inappropriate data
type matching;
- BUG#8768: Functions: For any unsigned data type, -ve values can be passed
and returned;
- BUG#8769: Functions: For Int datatypes, out of range values can be passed
and returned;
- BUG#9078: STORED PROCDURE: Decimal digits are not displayed when we use
DECIMAL datatype;
- BUG#9572: Stored procedures: variable type declarations ignored;
- BUG#12903: upper function does not work inside a function;
- BUG#13705: parameters to stored procedures are not verified;
- BUG#13808: ENUM type stored procedure parameter accepts non-enumerated
data;
- BUG#13909: Varchar Stored Procedure Parameter always BINARY string (ignores
CHARACTER SET);
- BUG#14161: Stored procedure cannot retrieve bigint unsigned;
- BUG#14188: BINARY variables have no 0x00 padding;
- BUG#15148: Stored procedure variables accept non-scalar values;
impossible view security".
We should not expose names of tables which are explicitly or implicitly (via
routine or trigger) used by view even if we find that they are missing.
So during building of list of prelocked tables for statement we track which
routines (and therefore tables for these routines) are used from views. We
mark elements of LEX::routines set which correspond to routines used in views
by setting Sroutine_hash_entry::belong_to_view member to point to TABLE_LIST
object for topmost view which uses routine. We propagate this mark to all
routines which are used by this routine and which we add to this set. We also
mark tables used by such routine which we add to the list of tables for
prelocking as belonging to this view.
