unchecked buffer size. This can be easily workarouned on
existing unpatched systems by increasing
mysqlnd.net_cmd_buffer_size ini variable to more than 8k
Binding params doesn't work when selecting a date inside a CASE-WHEN
(http://bugs.mysql.com/bug.php?id=49406)
The MySQL server sends MYSQL_TYPE_NEWDATE values as clear text, even
when PS are used and thus the binary protocol are used. Changing the
handler for the type.
- memory allocated with spprintf, or likes, outside of mysqlnd's
allocator functions should not be freed by the mysqlnd's allocator
(a wrapper around emalloc/malloc).
- memory allocated by the mysqlnd's allocator should only be freed
by it.
- add a mode to track memory usage (malloc/free)
needed to move to a new structure MYSQLND_STMT. Makes
the code cleaner and less error-prone.
Also fix PDO/MySQL which directly touch mysqlnd internals
instead of using API calls.
some reason. Double free of the data, which led to valgrind warnigns.
The fix actually optimizes the code in this cases because the old code
used copy_ctor while the new one skips it because it is not needed.
Transferring data ownership and nulling works best, for PS where we
always copy the string from the result set, unlike the text protocol.
We need to clone them, if there will be a transformation (convert_to_xxx)
which will change the origin.
- Make mysqlnd more compatible to libmysql, in this case if the execute of
a statement fails set the state of the statement back to PREPARED
- A test case to check the case of a failing statement.
- Clean up a bit a type mess - 4 types less. No need to have aliases
for the same thing (unification is the name).
- New macro for Johannes mysqlnd_stmt_ro_result_metadata
----------------------------------------------------------------------
- Fix BIT problem for BIT values represented with 5 bytes. Typo.
- Make it possible with an ini variable to switch off/on statistics
collection.
- Compile-out debug checking of uneaten data from the line, when the
build is release. According to callgrind this was eating some percentage.
