anddatabase_info()
). - Fix: Missing character sets for automatic translations.
- (PYFB-64) - cursor.description throws ReferenceError after executemany INSERT

Version 1.4.11¶
- (PYFB-58) Severe performance loss and minor memory leak
Version 1.4.10¶
- (PYFB-54) Windows 7x64 and FB2.5.2x32 Python2.7: Error in Registry Path. FDB driver does not find the library fbclient.dll
- (PYFB-55) get_sql_for incorrect generate sql query for Views
- (PYFB-56) schema.reload typing mistake for views
- (PYFB-57) role.privileges does not return correct privilege list
Version 1.4.9¶

Version 1.4.8¶
- Enhancement to automatic client library location detection on POSIX. Now it also looks at LD_LIBRARY_PATH dir if specified.
Version 1.4.7¶
- Forgoten debug printout removed. Annoying for Python 2.x users, fatal for 3.x users.
Version 1.4.6¶
Bugs Fixed¶
- (PYFB-50) Exception ReferenceError: ‘weakly-referenced object no longer exists’ in PreparedStatement and Cursor
Version 1.4.4¶
Improvements¶
- (PYFB-47) Firebird client library path added as optinal parameter to
fdb.connect()
andfdb.create_database()
.
Bugs Fixed¶
- Additional fix related to PYFB-43
- Additional correction for unregistered problem with circular ref. between PS and Cursor when explicit PS is executed.
Version 1.4.2¶
Improvements¶
In relation to PYFB-43 I had to make a backward incompatible change to event processing API. Starting from this version EventConduit does not automatically starts collection of events upon creation, but it’s now necessary to call
begin()
method. To mitigate the inconvenience, EventConduit now supports context manager protocol that ensures calls to begin() and close() via with statement.In relation to PYFB-39 I have decided to drop support for implicitly cached and reused prepared statements. I never liked this feature as I think it’s a sneaky method how to put some performance to badly written applications that in worst case may lead to significant resource consumption on server side when developers are not only lazy but also stupid. It was implemented for the sake of compatibility with KInterbasDB.
This change has no impact on API, but may affect performance of your applications.
Bugs Fixed¶
- PYFB-44 - Inserting a datetime.date into a TIMESTAMP column does not work
- PYFB-42 - Python 3.4 and FDB - backup throws an exception
- Unregistered - Fixes in monitor.TransactionInfo
Version 1.4.1¶
Improvements¶
- PYFB-40 - fbclient.dll is not found if not in path.
Aside from registry lookup, client library isn’t loaded until first call to
fdb.connect()
,fdb.create_database()
orfdb.load_api()
(which now supports optional specification of Firebird Client Library to load). - Adjustments for Firebird 3.0 (Alpha1)
- Properties
version
andengine_version
added tofdb.services.Connection
Bugs Fixed¶
- Unregistered - isolation_level parameter for fdb.connection has no effect.
- Unregistered - Information gathered from monitoring tables is not properly dropped upon refresh request.
Version 1.4¶
New Features¶
fdb.schema
submodule extended with support for user privileges.
Improvements¶
fdb.services.User.load_information()
method to load information about user from server.fdb.ibase
content cleanup and additions.fdb.blr
submodule with BLR definitions.
Bugs Fixed¶
- PYFB-37 - Unicode Strings incorrect not allowed for insertion into BLOB SubType 1.
Version 1.3¶
New Features¶
fdb.monitor
submodule for access to / work with monitoring tables.- New
fdb.Connection.monitor
property for access to monitoring tables.
Bugs Fixed¶
- Unregistered: Bug in
fdb.schema.Schema.close()
andfdb.schema.Schema.bind()
.
Version 1.2¶
New Features¶
fdb.schema
submodule for access to / work with database metadata.fdb.utils
submodule with various helper classes and functions.- New
fdb.Connection.schema
property for access to database schema. - New
ConnectionWithSchema
connection class that provides more direct access to database schema than Connection. - New
fdb.Connection.firebird_version
,fdb.Connection.version
andfdb.Connection.engine_version
properties. - New Connection.ods read only property that returns ODS version number of connected database. There are also new module-level constants ODS_FB_20, ODS_FB_21 and ODS_FB_25.
- New
fdb.Connection.query_transaction
property. This is ReadOnly ReadCommitted transaction that could be active indefinitely without blocking garbage collection. It’s used internally to query metadata, but it’s generally useful.
Improvements¶
Optional PEP 249 (Python DB API 2.0) Extensions
Connection.Error, Connection.ProgrammingError, etc.
All exception classes defined by the DB API standard are exposed on the Connection objects as attributes (in addition to being available at module scope).
Cursor.connection
This read-only attribute return a reference to the Connection object on which the cursor was created.
Cursor.transaction read-only attribute returns a reference to the Transaction object on which the cursor was created.
Optimized wekref management, especially for PreparedStatement.
create_database now supports two methods for database screation. You can specify CREATE DATABASE statement (as before) or provide set of named database parameters (SQL statement is created automatically from them).
Functions connection and create_database now take optional keyword parameter connection_class to obtain instances of different class instead Connection.
Support for legacy (pre-2.5) shutdown mode with mode fdb.services.SHUT_LEGACY.
fdb.Cursor.executemany()
returns self, so it could be used directly as iterator.Documentation inprovements.
Bugs Fixed¶
- Unregistered: buffers parameter of fdb.connection doesn’t support values greater than 255.
- Unregistered: Lowercase character set name passed to fdb.connect may result in wrong funcion of automatic data conversions and other failures (exceptions raised).

Other changes¶

- Reading output from Services now uses more efficient method to get data from server.

Version 0.7.2¶
New Features¶
- Python 3 Support (thanks to Philippe Makowski)
- Support for Distributed Transactions
And as always, some (unregistered) bugs fixed.
Version 0.7.1¶
Bug fixes.
Version 0.7¶
Initial release.
Almost feature-complete (ready for 95% of users), but it could be still buggy (it’s beta!), and the code wasn’t optimized for size and speed. In all other ways it’s ready for wide testing.
What’s missing¶
- Distributed transactions
- ARRAY support
- EVENTs support
- Stream BLOBs
- TRACE service
- Documentation (but you can use KInterbasDB one as FDB is as close to it as possible).
- Python 3.x support (haven’t had time to test it, but it shouldn’t be hard to make it work there)
