Subject: [Engine-devel] LOCALFS path validation
Hello,
I'm starting to know the engine code. I chose a little unstandardized
behaviour to follow through the devel process. I have a patch and
I'd like to know if you fell relevant to correct this issue:
- Description: Adding a LOCAL storage [1], webadmin does not validate
path against regex, sendind the invalid path (with final slash) to
vdsm [2] [3]. But, adding a NFS storage, the path is validated
before contacting vdsm [4] avoiding extra vdsm processing and
quickly/clearly informing user about what's wrong.
- Expected result: Same behaviour to NFS and LOCALFS storage path
validation. Validate LOCALFS path in webadmin before send it to vdsm
[5].
you may and should send a patch :)
- Newbie doubt: Wouldn't be better to validate the both local and nfs
path on the backend, achieving all user interfaces/APIs?
Because we have a rich client app (gwt), we can perform the
validation also in the client side very easily,
we do that to avoid unnecessary calls to the backend side, and to
have a better& responsive ui
(client side validation is performed instantly - without the need to
wait).
Anyway, every validation performed in the client side needs to be
performed also in backend side (for api, and other reasons (security?)).
the client side can validate the format of the path, not if it really
exists.
do you mean local storage via the wizard, or just adding another
storage domain?
the 'configure local storage' wizard requires the host to be in
maintenance, which may or may not be a problem to implement this type
of validation.
I mean just adding a LOCALFS storage domain with an invalid path, like this:

Currently we have this:

I sent a patch...

... in order to do this:

Just like "New NFS Domain" currently does:
