- Improved solution by adding an else stetment so that do find next is avoided if erorr occurs, but we still return zero files found instaed of an error
mysys/my_lib.c:
Add else statment so that if a directory can't be read because of access denied it will be skipped and zero files returned.
Use strnmov instead of strmov to avoid writing after end of buffer
If the second or the third argument of a BETWEEN predicate was
a constant expression, like '2005.09.01' - INTERVAL 6 MONTH,
while the other two arguments were fields then the predicate
was evaluated incorrectly and the query returned a wrong
result set.
The bug was introduced in 5.0.17 when in the fix for 12612.

- Grab the path from "configure --sysconfdir=<path>" and set it as
the first place to look for my.cnf files
Do this both in Makefiles for libmysql and mysys
- Patch provided by Francesco Riosa. Thank you!
libmysql/Makefile.shared:
Grab the path from "--sysconfdir=<path>" into the defined variable DEFAULT_SYSYCONFDIR
mysys/Makefile.am:
Grab the path from "--sysconfdir=<path>" into the defined variable DEFAULT_SYSYCONFDIR
mysys/default.c:
Use DEFAULT_SYSCONFDIR as first place to look for my.cnf file if "--sysconfdir=<path>" been specified as argument to configure
env variable name is fixed.

The function agg_cmp_type in item_cmpfunc.cc neglected the fact that
the first argument in a BETWEEN/IN predicate could be a field of a view.
As a result in the case when the retrieved table was hidden by a view
over it and the arguments in the BETWEEN/IN predicates are of
the date/time type the function did not perform conversion of
the constant arguments to the same format as the first field argument.
If formats of the arguments differed it caused wrong a evaluation of
the predicates.

too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume
100MB of RAM. Once this limit has been reached, the server will
refuse to prepare a new statement and return ER_UNKNOWN_ERROR
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared
statements is now available through a global read-only variable
@@prepared_stmt_count.
mysql-test/r/ps.result:
Test results fixed (a test case for Bug#16365)
mysql-test/t/ps.test:
A test case for Bug#16365 "Prepared Statements: DoS with too many
open statements". Also fix statement leaks in other tests.
sql/mysql_priv.h:
Add declarations for new global variables.
sql/mysqld.cc:
Add definitions of max_prepared_stmt_count, prepared_stmt_count.
sql/set_var.cc:
Implement support for @@prepared_stmt_count and
@@max_prepared_stmt_count. Currently these variables are queried
without acquiring LOCK_prepared_stmt_count due to limitations of
the set_var/sys_var class design. Updates are, however, protected
with a lock.
sql/set_var.h:
New declarations to add support for @@max_prepared_stmt_count.
Implement a new class, where the lock to be used when updating
a variable is a parameter.
sql/sql_class.cc:
Add accounting of the total number of prepared statements in the
server to the methods of Statement_map.
sql/sql_class.h:
Add accounting of the total number of prepared statements in the
server to the methods of Statement_map.
sql/sql_prepare.cc:
Statement_map::insert will now send a message in case of an
error.
