Counter Strike Source 18.2.2025 Update broke Source.Python

[srpg]

Hi, after todays update of css, sp is no longer working

Here is the error it shows when it attempts to load before crashing

[2025-02-18 22:17:05]: Failed to load plugin "addons/Tickrate_Enabler"
[2025-02-18 22:17:05]: [Source.Python] Loading...

I can confirm the update also broke SourceMod, and they're actively getting a fix out.

Not sure about SourcePython's speed of development though.

With everything gone to 64-bit this is going to take some time. The developer said that nothing will be done until the middle of next week. Valve always massively breaks thing when away for a while.

The forums aren’t active, where have the devs said this? Last time I saw Ayuto wasn’t interested in working on the 64bit version of this at all, not to mention the Python version itself is 7 versions behind.

Fair enough I stand corrected. If it helps debugging, our community reverted back to EventScripts with SPE because that still works somehow.

EventScripts works because it uses a for (int i=3;i<999;i++) to determine the current version until it finds it while we use an hard-coded definition from the SDK. That said, you guys can try to increment it manually:

Try to open your source-python/bin/core.<dll/so> file with a text editor that won't mess with the encoding (such as notepad++) and replace ServerGameDLL011 with ServerGameDLL012.

Though you are likely to face other issues related to outdated data.

I have tried earlier to change ServerGameDLL010 to ServerGameDLL011 without any success, giving [Source.Python] Could not retrieve interface ServerGameDLL011

Current version appears to be 12.

Hello there. I've tested a janky SP build against the latest SDK and also some updated data. CS:S on linux only. It seems to generally work and should help you get at least some plugins running.

P.S. Auto-updater is disabled in there

thanks sp loads now but crashes on my private plugin giving following error, i haven't traced yet which plugin causes it:

Edit solved the issue

That loads but if a plugin uses anything with hooks I believe it's still crashing.

RecursionError: maximum recursion depth exceeded while calling a Python object

[srpg]

I don't get those errors, my plugin uses hooks like weapon purchase, weapon pickup(can't remember proper name via phone), the other for command run(can't remember proper name via phone), post_think, pre_think and round end hook to block, i am running linux server

Hooks work fine, however that RecursionError is weird. Care to give some code that can reproduce the problem?

[saltysteev]

Edit: Looks like the hooks exceptions were on my end.

However, I'm getting a Segmentation fault when trying to load any model using engine.precache Model. Specifically in a @event player_spawn
