The problem of php mirror.php --gc command

[peter279k]

After looking at this code snippet, it seems that this will remove the files are on p folder.

That is, it will clean the outdated Composer V1 mirror files.

What about the outdated Composer v2 mirror files? (These files will be on p2 folder) Are they need to be removed?

It seems that the outdated files about V2 will be removed during v2 mirror syncing.

If I don't run php mirror.php --v1 command to build the Composer V1 mirrors, I don't need to run php mirror.php --gc every hour?

I notice that following message snippets when the it doesn't have Composer v1 mirror:

Mirror  job failed at 2020-11-10 16:09:55

It seems that the php mirror.php --gc command doesn't necessary to run if the Composer v1 mirrors are not on server.

Right, running the gc command is not needed if you only run --v2. I added this in the README now, and I'll make sure the gc command exits early if configured to only have v2.

And yes you are right, the v2 files get deleted/cleaned up as part of the regular v2 updates, v1 did not have an update feed so we could not clean up deleted files there.
