Subject [jira] [Commented] (VFS-661) Ability to get "real"/"native"/"physical" file name
Date Wed, 18 Apr 2018 14:24:00 GMT

Boris Petrov commented on VFS-661:
----------------------------------

I'm not sure what code sample you need. I can explain our use case - we are saving additional
metadata for each file in a file system in a database. We walk the file system, get each file
and use that as an ID in the DB. So in the DB we're going to have *smb://localhost/share/folder*
as an ID. Then, when someone requests a file, we get it from the filesystem and return the
metadata associated with it from the DB. However, you can imagine that when someone requests
*smb://localhost/share/FOLDER*, we do find the file but the DB doesn't return the metadata
as the ID is wrong and hence we return a wrong result to the user - we've found the correct
file but haven't found the correct metadata.

And, as I said, there is nothing we can do about it as VFS doesn't give us the "real" name
so we have no way of finding the metadata associated with it.

> On case-insensitive file systems (local FS on Windows; Samba; etc) resolving a file ignores
the case that is used. For example, if there is a folder like: *smb://localhost/share/folder*
and is resolved with *smb://localhost/share/FOLDER* it would work and return the same folder.
However, there is no method in the *FileObject* interface that allows us to get the "real"/"physical"
name of the folder - i.e. *folder*. All of the methods would return *FOLDER* in this case.
> We have a major usecase where we need that. The only solution I can think of is getting
the parent folder, going through its children and thus finding the correct case but the performance
of that would be horrible.
