Kyle should we undraft this? I still see < 3.13 in places.

[altendky]

#19062 makes this a touch simpler. i was going to wait for that just to avoid thrash. note that i think there are going to be some other dep issues and this isn't meant to actually get us supporting python 3.13+. just not getting in the way of people trying to fiddle themselves.

tl;dr, i expect to undraft it later today.

[altendky]

So it seems I had misunderstood something when chatting with folks that had tried to run on 3.13+. I don't think that the pyinstaller bump really changed much after all. Sorry about that. Anyways, undrafted and ready to go pending CI and a review.

So it seems I had misunderstood something when chatting with folks that had tried to run on 3.13+. I don't think that the pyinstaller bump really changed much after all. Sorry about that. Anyways, undrafted and ready to go pending CI and a review.

To get things (almost)working with python3.13, I had to:

• update install.sh to let it work with 3.13
• bump pyinstaller and typing-extensions 4.12.2 (it looks like you already bumped this in main)
• edit this to include zstd in versions < 3.14

  chia-blockchain/pyproject.toml

  Lines 72 to 75 in 1062ab4

  	zstd = [
  	{version=">=1.5.5.1", python = "<3.12"},
  	{version=">=1.5.5.1", python = "3.12", source="chia"},
  	]

• This let me build, but when I would run chia start node I would get:

Exception ignored in: <function _SelectorTransport.__del__ at 0x7addfc29cfe0>
Traceback (most recent call last):
  File "/usr/lib/python3.13/asyncio/selector_events.py", line 872, in __del__
    self._server._detach(self)
TypeError: PausableServer._detach() takes 1 positional argument but 2 were given
Exception ignored in: <function _SelectorTransport.__del__ at 0x7addfc29cfe0>
at pypException ignored in: <function _SelectorTransport.__del__ at 0x7addfc29cfe0>

• I read up and saw that there were changes to python3.13's implementation of asyncio, and wasn't sure if this was necessary/helpful, but I bumped these to the latest:

  chia-blockchain/pyproject.toml

  Lines 41 to 43 in 1062ab4

  	aiofiles = ">=24.1.0" # Async IO for files
  	aiohttp = ">=3.10.4" # HTTP server for full node rpc
  	aiosqlite = ">=0.20.0" # asyncio wrapper for sqlite, to store blocks

• After updating those, when running chia start node I would get:

Exception ignored in: <function _SelectorTransport.__del__ at 0x7c07ef7b4ea0>
Traceback (most recent call last):
  File "/usr/lib/python3.13/asyncio/selector_events.py", line 872, in __del__
    self._server._detach(self)
TypeError: PausableServer._detach() takes 1 positional argument but 2 were given

• I then went and made some changes to https://github.com/Chia-Network/chia-blockchain/blob/main/chia/server/chia_policy.py since it was the only place I saw that referenced PausableServer, and because the robots told me to
• I made these changes (minus the change on line 68): wallentx/billy-blockchain@main...wallentx:billy-blockchain:wallentx/python313#diff-412133e6847d450b408322e9d44cace7a2bb0a3de76c819836e00dc17a320aee
• After doing this, everything seemed to work fine - EXCEPT nothing could reach my full-node.. My full-node was working, and was syncing stuff, but I would get a transport error when anything would try to reach the full node
• I just now noticed that I might need to change line 68 https://github.com/wallentx/billy-blockchain/blob/d3b6706da2f5d61b03d4b92240144e97d9031ed3/chia/server/chia_policy.py#L68 so maybe it will work now, but my server is currently off for rack arranging
