d72f605a67 Calls to _mysql__fetch_row() might move the row tuple, so use a PyObject **. 
Thanks to Andy Martin for finding this.

40c7a6383e Mark connection open, even if open failed, for proper error reporting. 
Then mark it closed so we don't try to close it.

31fb50202d Lots of new __doc__ strings and other odds and ends 
for new pydoc module in Python 2.1.

Exceptions have been moved into _mysql_const/exc.py.
Mostly this is for documentation purposes. Mostly.

c3d23b6858 _mysql: Move type converter initialization outside of module. When opening 
the connection, a mapping of MySQL types to Python functions may be passed
as the keyword argument conv. This is stored as the converter attribute
on the connection object, and may be modified, assigned, etc.

MySQLdb: Build full converter dictionary, pass along to _mysql when
creating a connection.

MySQL_doc: Fixed a minor documentation bug.

8ac921c304 Added some new result object methods for fetching many or all rows, 
which should speed things up a bit. Not that it's slow...

Records whether the result was obtained by mysql_store_result or
mysql_use_result so it can avoid giving up the global interpreter
lock when store was used. I'm assuming the other functions which
return a result set (i.e. mysql_list_dbs, mysql_list_tables, etc.)
effectively use mysql_store_result.

31a706efde Finally chased down an ugly memory leak in _mysql. Tested with a script 
I got from mxODBC author Marc-Andre Lemburg, which revealed the leak in
the first place.

Added a connection.rollback() method that always raises an
OperationalError, since MySQL doesn't have transactions.
connection.commit() still succeeds without doing anything.

e1970cf20b Updated _mysql to do some type conversion. Adds a dictionary type_conv 
which makes MySQL field types to Python functions which perform the
conversion. All numeric types except DECIMAL are mapped into either
PyInt or PyLong, and the floating point types are mapped into PyFloat by
default. Types which are not represented in the dictionary are returned
as strings.

Modified MySQLdb to adjust type_conv so that the various date/time types
are returned as DateTime objects.

Bug: If you were to delete or assign type_conv, bad things would happen.
I haven't actually tried this, but it wouldn't be good. May add an extra
reference count to prevent this, haven't really decided.

161f66f556 Added a _mysql.quote_row() function which takes a row of data as a tuple 
and quotes it, converting None into NULL.

MySQLdb.py is the DBI-1.1 compatible wrapper.

To do: Type conversions for fetch_row().

563ab10307 Added access to various MySQL constants, plus field flags. More specific 
exception handling. And a light sprinkling of bug fixes throughout.

I'm thinking this part is done, unless I find the need to add another
feature or two for the Python DBI. All the mysql_* calls are duplicated
either as functions, connection objects, or result objects, with the
exception of deprecated functions and a lot of field_* functions.
Access to the MYSQL_FIELD members is done mostly through
ResultObject.describe(), which returns almost all information for all
the fields. ResultObject.field_flags() returns the flag values.

c02de220c3 Nearly everything that should work now works. Need to add a few more 
methods to the Result object. Also need to rip out the Field object;
ended up not needing it. It's just cruft now.

Notes: NULL values represented by Python None object. fetch_row() returns
None at the end of the query set, which doesn't print. Conversion of data
types will be done in a Python wrapper module. Need to figure out a way
to read a fixed number of rows without having to twiddle with the global
interpreter lock all the time. Not a big problem if store_result() has
been used, but is trickier if use_result() was used.

638b154e72 A home-made mysql interface for Python so I can learn the API. It's almost 
sorta functional. The problem with the existing interface (minor) is that
it's for 3.21 mysql. Not a huge problem, but it doesn't seem to have a stable
maintainer at the moment either.

Tommorrow I work on result objects so I can get queries done and stuff.
