Does your code create this:

-rw-r--r-- 1 www-data www-data    0 2025-09-26 22:08:17 gmail_block_log.lock

And if it does, why?

Yes it does, that's to prevent 2 simultaneous requests to edit the file at the same time. If a file is locked while it is being edited, another request has to wait for it to be released (unlocked) before being able to edit it

Is the file persistent; it remains until the MOD is triggered, at which point it is removed, the file appended, and a new lock file created? This file didn't exist when I was testing the MOD.

The lock file is actually for log rotation. It should only create the lock file when it's time to rotate the logs. I'll update the mod to do that.

But as for keeping or deleting the lock file, it is a best practice to keep it around permanently. It’s just a tiny empty file that serves as a synchronization point. The cost is negligible, and it avoids the race condition I described. But I can delete it for Unix/Linux systems safely but not for Windows where deleting may fail if another process has it open. I'll include that in the update.

Thank you for the explanation.
