PR Summary
This PR addresses a critical memory leak issue in Umami's geolocation functionality by modifying the MaxMind database initialization process.
- Moved MaxMind database initialization outside
getLocationfunction insrc/lib/detect.tsto prevent repeated loading - Critical bug: Undefined
resultvariable used ingetLocationfunction needs to be defined - Missing error handling: No cleanup/close handling for MaxMind database on application shutdown
- Potential race condition:
initializeMaxmind()called but not awaited properly - Type safety issue:
lookupPromiseusesanytype instead of proper MaxMind types

is not the best solution because the process hangs( |

I don't understand how this is any different than the previous solution. The |
I updated the solution a bit and it tentatively works |
|
Is it possible just updating the maxmind library fixes it? |
It didn't work for me. But maybe I did something wrong |
I already created issue
#3204
I tried to fix it and it seems to have solved the problem
But my solution is not very pretty
But I think it will be useful to you
