In case of an (automatic) reconnect the connection property
connection_id was not updated, since there is no callback
functionality in Connector/C available to notify the application
that a reconnect occured. Instead of obtaining the connection_id
via MemberDef, connection_id is now implemented as getter function.
Methods which are defined via PyMemberDef with flag METH_VARARGS
and have only one parameter are using METH_O now: Instead of parsing
and converting parameter via PyArgs_ParseTuple we now check the type
and convert passed python object directly to the corresponding c type.
Fixed crash in escape_string method of connection object:
Instead of PyMem_RawCalloc we allocate memory via PyMem_Calloc, since
the memory will be freed by PyMem_Free (instead of PyMem_RawFree).
The connection method now offers the option of specifying
the version of the TLS protocol using tls_version:
connection = mariadb.connect(tls_protocol="TLSv1.2")
Replaced collections.named_tuple by C-Pythons PyStruct_Sequence.
All conversion are done now before fetching a row: converting to
other result types than tuple (named tuple or dict) now have less
overhead and are significantly faster.
- All parameter exceptions are now ProgrammingErrors
- A dictionary now might contain more keys than
placeholders in statement
- Fixed unhandled exception when using dictionary as parameter
Display status of connection, cursor and pool class in
string representation.
If an object (cursor, class, connection pool) was closed, the
string representation (tp_repr) now shows the status of the object.
Example:
>>> import mariadb
>>> connection=mariadb.connect()
>>> connection
<mariadb.connection connected to 'localhost' at 0x7f94d77c3b40>
>>> connection.close()
>>> connection
<mariadb.connection (closed) at 0x7f94d77c3b40>
Since memory for stack allocation is limited, we need to allocate
memory from the heap, otherwise in case of large strings escape_string
method might crash.
Added connection attribute server_version_info and (for compatibiliry)
get_server_version() method.
Both return a tuple, describing the version number of connected server
in following format: (MAJOR_VERSION, MINOR_VERSION, PATCH_VERSION)
Connection attributes in PyMember definition will be accessed as
string constants instead of Python Object, so the object will be
created only if the member will be accessed in python code and it's
reference count doesn't need to be decrement when the connection
class will be deallocated.
The connect() method now accepts an addtional parameter
converter which points to a dictionary, containing one or more conversions.
A conversion must be specified in the form {FIELD_TYOE : conversion_function}
Fixed default behavior of autocommit: If not autocommit mode was specified,
autocommit will be off by default (see https://www.python.org/dev/peps/pep-0249/#commit).
Added new keyword autocommit for connection class which might have the following values:
- None: use server default setting
- True: turns autocommit on
- False: turns autocommit off
- added a thin python wrapper around mariadb module
- added constansts under mariadb.constants (CLIENT, CURSOR, INDICATOR)
- bench and test are now in testing subdirectory
- updated documentation
