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.
Clearly separated fetching (physical reading) from decoding phases (data
interpretation). Threaded fetching added but disabled as needs more work for
Windows. For Linux needs some touches to add pthreads if this is enabled,
probably with a compile-time switch.
The code reorganisation makes it easy to add also async API, similar to
cURL's one.
- 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.
