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.
