From c8f66e0a72b550f9b36d5152d42abb5497eea156 Mon Sep 17 00:00:00 2001 From: Loom Agent Date: Wed, 8 Jul 2026 22:28:21 +0000 Subject: [PATCH 1/2] fix(async_subtensor): don't close shared connection in register methods register, burned_register and register_limit used `async with self:`, whose __aexit__ calls self.substrate.close(). On a long-lived, shared subtensor this closed the caller's websocket as soon as the method returned, breaking every subsequent query. Every other async method already assumes an open connection and leaves it open; these three were the only outliers. Add an _ensure_connection async-context helper that initializes the substrate without closing it, and use it in place of `async with self:`. --- bittensor/core/async_subtensor.py | 20 ++++++++++++++++--- tests/unit_tests/test_async_subtensor.py | 25 ++++++++++++++++++++++++ 2 files changed, 42 insertions(+), 3 deletions(-) diff --git a/bittensor/core/async_subtensor.py b/bittensor/core/async_subtensor.py index e1f1d1b51d..e74bc92d22 100644 --- a/bittensor/core/async_subtensor.py +++ b/bittensor/core/async_subtensor.py @@ -1,4 +1,5 @@ import asyncio +import contextlib import copy import ssl from datetime import datetime, timezone @@ -358,6 +359,19 @@ async def __aenter__(self): async def __aexit__(self, exc_type, exc_val, exc_tb): await self.substrate.close() + @contextlib.asynccontextmanager + async def _ensure_connection(self): + """Ensure the substrate connection is open for the duration of a single call + without closing it afterwards. + + Unlike ``async with self:``, this must be used by methods that run on a + long-lived, shared connection: ``__aexit__`` calls ``self.substrate.close()``, + so ``async with self:`` inside a method would close the caller's connection as + soon as the method returns, breaking every subsequent query on that subtensor. + """ + await self.initialize() + yield + # Helpers ========================================================================================================== async def _decode_crowdloan_entry( @@ -7216,7 +7230,7 @@ async def burned_register( Notes: - Rate Limits: """ - async with self: + async with self._ensure_connection(): if netuid == 0: return await root_register_extrinsic( subtensor=self, @@ -8507,7 +8521,7 @@ async def register( Notes: - Rate Limits: """ - async with self: + async with self._ensure_connection(): if netuid == 0: return await root_register_extrinsic( subtensor=self, @@ -8586,7 +8600,7 @@ async def register_limit( - Rate Limits: """ check_balance_amount(limit_price) - async with self: + async with self._ensure_connection(): return await register_limit_extrinsic( subtensor=self, wallet=wallet, diff --git a/tests/unit_tests/test_async_subtensor.py b/tests/unit_tests/test_async_subtensor.py index 94029b20ab..156042f565 100644 --- a/tests/unit_tests/test_async_subtensor.py +++ b/tests/unit_tests/test_async_subtensor.py @@ -194,6 +194,31 @@ async def test_burned_register(subtensor, fake_wallet, mocker): ) +@pytest.mark.asyncio +async def test_register_family_does_not_close_shared_connection( + subtensor, fake_wallet, mocker +): + """register/burned_register/register_limit must not close the substrate connection + they share with the caller.
