From ad1fcc20450906df701e924676a43cb12e73749f Mon Sep 17 00:00:00 2001 From: QuarkChain Dev Date: Fri, 13 Mar 2026 04:06:05 +0100 Subject: [PATCH 01/14] modernize asyncio usage for Python 3.10+ compatibility MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Python 3.10 deprecated the loop= parameter in most asyncio APIs, and Python 3.12 removed it entirely. This removes all deprecated patterns across the codebase and adopts modern asyncio idioms. Changes: - Remove loop= parameter from asyncio.Event, asyncio.wait, asyncio.ensure_future, asyncio.start_server, open_connection, etc. - Replace asyncio.ensure_future() with asyncio.create_task() - Replace get_event_loop().run_until_complete() with asyncio.run() - Replace asyncio.get_event_loop() with asyncio.get_running_loop() where inside a running event loop - Add _get_or_create_event_loop() helper in utils.py for call sites that run before the loop starts (SlaveServer, SlaveConnectionManager) - Replace asyncio.Future used as a one-shot signal with asyncio.Event (active_future → active_event, ping_received_future → ping_received_event) - Make start()/shutdown() methods async where they previously called loop.run_until_complete() internally - Update eth_hash import: BasePreImage → PreImageAPI (eth-hash >=0.5 API) - Update cryptography API: EllipticCurvePublicNumbers.from_encoded_point → EllipticCurvePublicKey.from_encoded_point - Add conftest.py to cancel pending asyncio tasks between tests - Replace assertRaisesRegexp (removed in Py 3.12) with assertRaisesRegex Co-Authored-By: Claude Sonnet 4.6 --- quarkchain/cluster/cluster.py | 8 +-- quarkchain/cluster/master.py | 52 +++++++++-------- quarkchain/cluster/miner.py | 2 +- quarkchain/cluster/protocol.py | 19 ++---- quarkchain/cluster/shard.py | 8 +-- quarkchain/cluster/simple_network.py | 25 ++++---- quarkchain/cluster/slave.py | 54 +++++++++-------- quarkchain/cluster/subscription.py | 4 +- quarkchain/cluster/tests/conftest.py | 17 ++++++ quarkchain/cluster/tests/test_miner.py | 33 ++++++----- quarkchain/cluster/tests/test_protocol.py | 28 ++++++--- quarkchain/cluster/tests/test_root_state.py | 16 ++--- quarkchain/cluster/tests/test_shard_state.py | 20 +++---- quarkchain/cluster/tests/test_utils.py | 17 ++++-- quarkchain/cluster/tx_generator.py | 2 +- quarkchain/p2p/auth.py | 8 +-- .../cancel_token/tests/test_cancel_token.py | 45 +++++++------- quarkchain/p2p/cancel_token/token.py | 27 +++------ quarkchain/p2p/discovery.py | 16 ++--- quarkchain/p2p/ecies.py | 3 +- quarkchain/p2p/p2p_manager.py | 11 ++-- quarkchain/p2p/p2p_server.py | 2 +- quarkchain/p2p/peer.py | 6 +- quarkchain/p2p/service.py | 6 +- quarkchain/p2p/tests/test_discovery.py | 58 ++++++++++--------- .../tests/test_peer_collect_sub_proto_msgs.py | 4 +- quarkchain/p2p/tests/test_peer_subscriber.py | 4 +- quarkchain/p2p/tests/test_service.py | 6 +- quarkchain/p2p/tools/paragon/helpers.py | 14 +++-- quarkchain/protocol.py | 20 +++---- quarkchain/tools/adjust_difficulty.py | 4 +- quarkchain/tools/client_version_poll.py | 2 +- quarkchain/utils.py | 37 ++++++++++-- 33 files changed, 318 insertions(+), 260 deletions(-) create mode 100644 quarkchain/cluster/tests/conftest.py diff --git a/quarkchain/cluster/cluster.py b/quarkchain/cluster/cluster.py index 1fb3cf13b..5b6271fda 100644 --- a/quarkchain/cluster/cluster.py +++ b/quarkchain/cluster/cluster.py @@ -106,7 +106,7 @@ async def run_master(self): extra_cmd += " --enable_profiler=true" master = await run_master(self.config.json_filepath, extra_cmd) prefix = "{}MASTER".format(self.cluster_id) -

98621eae92a535c4d72ce8307ab7f55ac06bd33c Mon Sep 17 00:00:00 2001 From: ping-ke Date: Thu, 26 Mar 2026 18:36:10 +0800 Subject: [PATCH 09/14] convert sync tests to async using IsolatedAsyncioTestCase - convert test_cluster.py and test_jsonrpc.py to unittest.IsolatedAsyncioTestCase - make create_test_clusters/shutdown_clusters async, ClusterContext async context manager - replace call_async() with await, assert_true_with_timeout with async_assert_true_with_timeout - replace _get_or_create_event_loop() with asyncio.get_running_loop() in master/slave - fix mock_pay_native_token_as_gas to support both sync and async wrapped functions - remove obsolete _get_or_create_event_loop, call_async, assert_true_with_timeout helpers - fix conftest to restore event loop after IsolatedAsyncioTestCase
