Feature-Request: A little more sophisticated directory locking

[gumata25]

I just ran into "Cannot set directory locks for the following folders" for the umpteenth time so I decided to finally google it and the best solution I found was to have a separate GlobalSettings.xml with deactivated directory locking and to pass it to FFS via command line (see viewtopic.php?t=650).

So I thought it might be time for a basic principle discussion. I have two suggestions for user convenience:

1.: It think it is necessary to have the possibility to turn off directory locking not only globally and not even just for each sync job but for each folder pair in a sync job.

2.: In my case I selected the "Mirror" synchronisation variant for the folder pair. Meaning I mirror from the read-only folder to a target folder. Why would FFS have to lock the source directory in that case? I don't get it. So I suggest to not lock it by default in the mirror case.

Is anything wrong with the assumption that these might be good ideas?

1. => Agreed, TODO
2. => Another sync might write to the source side at the same time.

=> 2. Ok, maybe I don't have the insight here so what exactly does directory locking do? Is it just for other sync jobs not to interfere? What about other processes then?

Correct. It is only so another FFS session does not run using the same location(s). It has no influence on any other program

Ok, thanks for the replies at all!

For security reasons, I have the same wish: mirror synchronization of server drives with a restricted user (readonly service user) on a local NAS.
Thank you in advance!
