Access denied on Geolite2-City.mmdb when running cscli hub upgrade while Crowdsec is running on Windows Platform

[cstisa]

What happened?

Dear Crowdsec Community,

When we perform a cscli hub upgrade or cscli hub upgrade --force on a host running Windows Server Operating System we have the following error :

C:\Windows\system32>cscli hub upgrade
level=info msg="Upgrading parsers"
level=info msg="crowdsecurity/http-logs: up-to-date"
level=info msg="crowdsecurity/mssql-logs: up-to-date"

C:\Windows\system32>cscli hub upgrade --force
level=info msg="Upgrading parsers"
level=info msg="crowdsecurity/geoip-enrich: up-to-date"
level=error msg="Failed to remove destination file before renaming: remove C:\\ProgramData\\CrowdSec\\data\\GeoLite2-City.mmdb: Access is denied." url="https://hub-data.crowdsec.net/mmdb_update/GeoLite2-City.mmdb"

It seems that it can not remove the GeoLite2-City.mmdb while Crowdsec Service is running

After stopping the service and running again the command the process is working as expected.

When there are no update of this mmdb Geolite file the process is working as expected.

What did you expect to happen?

The process of running cscli hub upgrade should work without any intervention (stopping) on the service.

How can we reproduce it (as minimally and precisely as possible)?

Perform a cscli hub upgrade on a command prompt with administrator privilege while crowdsec is running and the Geolite files are not up to date.

Anything else we need to know?

Hello,

This one might be a bit tricky: the MMDB files are mmap()'ed (or the Windows equivalent in your case) on startup, and windows (AFAIK) forbids deleting/replacing a file that has valid handles pointing to it.

This issue was most likely hidden in the past as we did not support automatically updating the datafiles, and after we did, the auto-update for the MMDB files was disabled server-side to workaround a crash while we implemented the fix in crowdsec.

We'll try to come up with a solution and let you know.
