🐛 Bug Report: Hot-swapping breaks when function is running locally

[kamarkiewicz]

👟 Reproduction steps

1. Create a new Appwrite project with a starter function using python-ml-3.11.
2. Run it with appwrite run function
3. Trigger a save action on src/main.py

👍 Expected behavior

Hot-swapping to work. Workaround is to edit node_modules/appwrite-cli/lib/utils.js#L12 with fs.lstatSync which doesn't follow symlinks.

👎 Actual Behavior

I just encountered the same issue while running a Python function locally with Appwrite CLI 6.2.2.

🔄 My Environment:

• OS: Ubuntu 22.04
• Appwrite CLI Version: 6.2.2
• Python Version: 3.12.3
• Function Runtime: Python 3.12
• Docker Installed: Yes

🐞 Issue Details:

Whenever I modify my function's code (even a single character), Appwrite detects the change and attempts to hot-swap the function. However, instead of applying the update correctly, it throws the same ENOENT error, failing to locate the Python binary inside .appwrite/hot-swap/runtime-env/bin/python.

⚠️ Error Output:

ℹ Info: Hot-swapping function.. Files with change are src/main.py Error: ENOENT: no such file or directory, stat '/home/atlasdev/projects/tasknotes/functions/Function Sample/.appwrite/hot-swap/runtime-env/bin/python' at Object.statSync (node:fs:1688:3) at getAllFiles (/usr/local/lib/node_modules/appwrite-cli/lib/utils.js:12:16) ...

🔍 Additional Findings:

I noticed that in .appwrite/hot-swap/runtime-env/bin/, the python, python3, and python3.12 binaries are symbolic links, but they appear to be broken (they don't point to valid files). This seems to be why stat fails when attempting to locate the binary.

Has there been any progress on fixing this in newer versions? If there's anything I can test to help debug, let me know!

Thanks!

@kamarkiewicz @TechAtlasDev thanks for raising the issue! seems like the issue might be isolated to python functions specifically as i just tried a node function and it worked with no issues.

I will begun investigation on this and let you know if a fix is available 👍
