symlink doesn't work

[leporel]

I upgraded from version 3.0.9 to version 4.0.4 (docker) Datasource pointing to a folder where there was a symlink to another folder stopped seeing files in this symlink, in the console writes pydio.grpc.data.sync.motto Empty Patch : nothing to do

Hi, thx for reporting. Just retested, definitely a regression in Minio. We'll see how to handle this, as we now use a forked version of minio anyway.

[cdujeu]

Hey, I commited a fix in the @main, you may test with the latest build ! https://download.pydio.com/pub/cells/dev/

[leporel]

Yes, now it seems scanner walk over files

But maybe i misunderstand new logic, .pydio is required in every folder, because i have error like this

according to the documentation must have read and write permissions on this folder and on the parent folder.

Following this logic, I mounted the folder in docker in read-only mode, because I'm worried about data safety and I'm afraid of unauthorized access. It worked before, I guess in v4 it's not possible now?

[cdujeu]

This is clearly not new, the .pydio created under each folder dates back to Cells v1 ... So i'm unsure of how that worked correctly in v3 in your case...

[cdujeu]

closing for now as the regression is fixed. please open a forum if required, thanks
