[See remaining text…] 

a) Safe use. This translates to extensive use of type hints and
annotations, including Protocols etc. Also many arguments are defined as
keyword only to avoid ambiguity and improve code readability. This is
one from main reasons why Python 3.8 is minimal version required.

b) Wrong run-time conditions (like not closed connection) and some
arguments are checked ONLY as asserts. So optimized Python code does not
performs any such checks. Note that used trace/audit could be also
affected by optimization (depends on how you use it, see firebird-base
documentation for details).

c) Compact code. It often means that latest Python features are used
anywhere it makes sense (that includes := operator etc.).

d) Simplicity. This for example also means minimal number of names
defined, so all various constants and flags used by Firebird API are
defined as Python enums/flags. That same apply to number of function
parameters (with few exceptions).

3. The driver uses “firebird.base” package, which is a collection of
   modules that have general applicability, like extended configuration,
   context-driven logging and trace/audit, hooks, work with structured
   binary buffers, extended data structures etc. See:
   https://pypi.org/project/firebird-base/
   and raw documentation at https://firebird-base.rtfd.io/
   This package is a shared base for current and future Python development
   projects under Firebird Project umbrella (currently the driver, soon the
   Saturnin and QA suite etc.)

The driver uses almost all features provided by “base” package, but
specifically the use of hook mechanism and context-driven logging and
trace/audit are potentially the most valuable improvements, so any
usability feedback would be appreciated. I also plan to take advantage
of extended configuration, so any ideas or suggestions about driver’s
configuration options would be appreciated.

4. With release of Firebird 4.0 beta 2, I started to adapt the driver to
   new Firebird version. Part of this adaptation is new architecture that
   moves some functionality into separate “inner” classes, so it could be
   switched at run-time according to used Firebird version (or ODS). So
   far, all information-related functionality (methods and properties) in
   Connection and Transaction was moved out into “Info” objects, accessible
   through “info” property (i.e. Connection.info. etc.). The
   Services class was renamed to Server, and over next month I’ll move out
   all services-related functionality into series of separate
   domain-specific inner objects like “backup”, “config”, “trace”, “users” etc.

The reference documentation is here:

5. Please note, that FDB is now considered as legacy driver, and its
   development will be discontinued together with 2.5 once Firebird 4.0
   will be released later this year. However, one FDB maintenance release
   is planned before that, so if you have any pending issues or pull
   requests for FDB, please let me know.
