"Not enough free space" when uploading: Sometimes no freeSpace calculation #27367

Somewhere between 20.0.1 and 20.0.9, the calculation of freespace when uploading was changed.

I'm using an app that uploads to not-yet-existing directories, relying on NC creating them implicitely which works fine, unless freeSpace is not calculated (and thus 0) which happens in this case.

Previously, file-upload.js OC.FileUpload.add() would just use the global freeSpace from $('#free_space').val(). Now, freeSpace is initialized as 0, and calculated for some data scenarios. If those scenarios are not met, it will remain 0, failing the upload with "Not enough free space".

freeSpace should be initialized to the global freeSpace as before, and then recalculated for specific situations to make sure freeSpace is valid in all situations.
