How to upgrade to the latest version!

2.4.0.dev (development stage/unreleased/unstable)¶

2.4.0¶

Optimization of the performance and revision of the life support of the ListenKey.

Changed¶

The management methods are no longer started individually in threads but together in an event loop in ‘run()’. By switching from threads to AsyncIO tasks, some time.sleep() could be replaced by asyncio.sleep()

Fixed¶

In _run_sockets() time.sleep() was mistakenly used instead of asyncio.sleep().
Keeping the ListenKey alive has been revised and now runs as an asyncIO task in the event loop of the stream. In the event of an exception due to an IP ban, the time window until the ban is lifted is extracted from the Binance response and now waits until then to continue. issue#330
Added exception handling for TypeError to subscribe_to_stream() and unsubscribe_from_stream().

2.3.0¶

Redesign and rewrite of connection.py, sockets.py as well as the loop and exception handling in manager.py and support for await get_stream_data_from_asyncio_queue(stream_id).

Runs perfectly on Python 3.7 to 3.12 on Windows, Linux and Mac!

Added¶

ubwa.api.get_listen_key()
Unit tests for python 3.7 to 3.12, extension of the tests.
Support and use of an asyncio.queue(). The parameter “process_asyncio_queue” for BinanceWebSocketApiManager() and create_stream() can be passed an async function, which is automatically added to the event loop of the websocket as an async task. Received websocket data can be conveniently awaited with await get_stream_data_from_asyncio_queue(stream_id) as an AsyncIO alternative to pop_stream_data_from_stream_buffer(). This is probably the smartest way to process data from the websocket and should be preferred to the stream_buffer and the callback function.
is_socket_ready()

Changed¶

Updated from websockets 10.4 to 11.0.3.
pop_stream_data_from_stream_buffer() returns None instead of False
The parameter throw_exception_if_unrepairable was removed by the UBWA Manager and replaced by the stream_signal STREAM_UNREPAIRABLE.
Info: https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/wiki/%60stream_signals%60
Many False values have been changed to None values in accordance with Python conventions.
shutdown_asyncgens() to _shutdown_asyncgens()
run_socket() to _run_socket()
_auto_data_cleanup_stopped_streams() now performs a check every 60 seconds and deletes the data from streams that have been stopped for more than 900 seconds.
datetime.utcfromtimestamp(stream_info['start_time']).strftime('%Y-%m-%d, %H:%M:%S UTC')) is obsolete and has been replaced by datetime.fromtimestamp(timestamp, timezone.utc).strftime('%Y-%m-%d, %H:%M:%S UTC').
Renamed stop_stream_as_crash() with _crash_stream()
Renamed is_stop_as_crash_request() with is_crash_request()
Renamed stream_is_crashing() with _stream_is_crashing()
Renamed stream_is_stopping() with _stream_is_stopping()

Fixed¶

In Websocket API wrong method names were used in logging.
Logging info in connection.py revised.
ubwa.api.get_open_orders() can now be used without the symbol parameter to query all open orders.
Completely revised the error handling.

Removed¶

Parameter throw_exception_if_unrepairable of BinanceWebSocketApiManager().
Exception StreamRecoveryError.
set_restart_request()
_restart_stream()
_keepalive_streams()
kill_stream()

2.2.0¶

This update is primarily aimed at stabilization. The loop management has been improved and runs absolutely fine in tests!

unicorn-binance-websocket-api can now also be installed on all architectures on which there are no precompiled packages from LUCIT. PIP now automatically recognises whether there is a suitable precompiled package and if not, the source is automatically compiled on the target system during the installation process with Cython. Even if you don’t have to do anything special, please note that this process takes some time!

Added¶

Parameter process_stream_data_async in manager.py to BinanceWebSocketApiManager() as global setting parameter and to create_stream() as stream specific parameter. This means it is possible to provide a global and a stream specific asyncio function as “process_stream_data” function.
Support for process_stream_data_async and specific_process_stream_data_async[stream_id] to socket.py.
Support for with-context to BinanceWebSocketApiSocket().
run_socket() to manager.py.
shutdown_asyncgens() to manager.py.
timeout parameter (float) to delete_stream_from_stream_list(), wait_till_stream_has_stopped() and wait_till_stream_has_started() with default value 10.0 seconds.
Automatic data cleanup of stopped web streams. issue#307 The UBWA Manager can be informed via the parameter auto_data_cleanup_stopped_streams=True that all remaining data within the UBWA of a stopped stream should be automatically and completely deleted (duration 60 sec). Default value is False. Also added the function remove_all_data_of_stream_id() and _auto_data_cleanup_stopped_streams() which are doing the cleaning up job.

Changed¶

Parameter process_stream_data in manager.py from False to None.
Parameter process_stream_signals in manager.py from False to None.
Usage of BinanceWebSocketApiSocket() in manager.py by using the new with-context and ubwa.run_socket() to close every websocket connection when leaving.
Now using wait_till_stream_has_stopped() in delete_stream_from_stream_list(). This avoids many errors ;)
Rewrite of the try-except and the finally code part for the loop handling in _create_stream_thread().

Fixed¶

Missing await of websocket.close() in socket.py.
Event loops were not closed in rare situations. Adjustments to _create_stream_thread(), create_stream() and _restart_stream()
In connection.py sys.exit() statements were used within an asyncio loop, this prevented the correct closing of the asyncio loops in rare cases and was replaced by return False.

Removed¶

import sys in sockets.py

2.1.4¶

Added¶

Websocket API: create_order() and create_test_order() - Support of parameter quoteOrderQty, Behavior: If activated, it replaces the quantity parameter.

Fixed¶

Websocket API: create_order() and create_test_order() - issue#353 and issue#352
Websocket API: create_order() and create_test_order() - trailingDelta is only used if stopPrice was not specified.
Binance futures testnet userData stream in restclient.py - issue#347

2.1.3¶

Fixed¶

Troubleshooting restart problems
manager.delete_listen_key_by_stream_id() used False instead of None

Stopping manager._restart_stream() if manager is stopping.

2.1.1¶

Changed¶

Rewrite of restclient.py and implementing usage of **params with UBRA.
False and None was used incorrectly in some cases, this has been unified.

Fixed¶

manager.wait_till_stream_has_stopped()

2.1.0¶

Added¶

Handling of not retrieved error messages in AsyncIO loops
Debug mode for AsyncIO tasks
manager.stop_manager() alias for manager.stop_manager_with_all_streams()
Support for with-context

Fixed¶

AsyncIO Loop handling and closing
Graceful shutdown in exception UnknownExchange
manager.wait_till_stream_has_started()

2.0.0¶

Added¶

Support for Python 3.11 and 3.12
Integration of the lucit-licensing-python library for verifying the UNICORN Binance Suite license. A license can be purchased in the LUCIT Online Shop: https://shop.lucit.services/software/unicorn-binance-suite
License change from MIT to LSOSL - LUCIT Synergetic Open Source License: https://github.com/LUCIT-Systems-and-Development/unicorn-binance-websocket-api/blob/master/LICENSE
Conversion to a C++ compiled Cython package with precompiled as well as PyPy and source code wheels.
Setup of a “Trusted Publisher” deployment chain. The source code is transparently packaged into wheels directly from the GitHub repository by a GitHub action for all possible platforms and published directly as a new release on GitHub and PyPi. A second process from Conda-Forge then uploads it to Anaconda. Thus, the entire deployment process is transparent and the user can be sure that the compilation of a version fully corresponds to the source code.

Changed¶

Added @staticmethod to many static mehtods.

Fixed¶

Typos and formatting
Shadow of a Python built-in in manager.get_human_bytesize(): bytes to amount_bytes

process_response parameter to ubwa.api methods to provide specific callback functions for specific responses
return_response parameter to ubwa.api methods to let the used method wait till the requested data is received via websocket, and then it returns it.

Changed¶

Use UnicornFy only for non api requests in sockets.py - if output="UnicornFy" is used for api then its just converted to a python dict.
ubwa.api methods do not need a stream_id/stream_label if there is only one valid websocket api. (Self-discovery of uniquely identifiable websocket api streams if no stream_id or stream_label was specified for identification.)
Renamed ubwa.api.test_create_order() to ubwa.api.create_test_order()
