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)
When using text protocol pending result sets weren't properly freed,
so executing another command on the same connection resulted in an error
"commands out of sync".
Beginning of MariaDB 10.5 metadata for JSON columns is stored
in extended field information, and the reported type is MYSQL_TYPE_BLOB.
We now check extended field information to return correct type and for
fetching values in correct format.
rowcount:
In case of an error, or if statement wasn't executed rowcount should be -1 (see PEP-249)
For DML statements the number of affected rows returned in OK packet by server:
> 0 for DML statements which modify or insert, e.g. ALTER TABLE or CREATE TABLE .. SELECT FROM
otherwise 0
For DQL statement
if field_count > 0: number of rows returned
otherwise affected rows returned in OK packet by server.
lastrowid:
if server returns no value (0) for last_insert_id, lastrowid should be None.
if last_insert_id is > 0, return it's value
When a value is returned as binary type (BLOB) but has a non binary collation,
it will be converted now as a unicode string and the binary flag will be ignored.
- 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
