CBRAIN/NeuroHub Release Notes

Version 6.0.0 Released 2020-08-19

More than 8 months have passed since the previous release, 5.3.0!

This release introduces the new GUI interface called NeuroHub.
The original CBRAIN interface is still all there; NeuroHub
is an additional set of pages providing a new look and feel, and
new capabilities. NeuroHub is still rather restricted in what
it can do, but users can easily switch back and forth between
the two interfaces at the push of a button (located at the top
and left on each interface).

New CBRAIN features: (some of these apply to NeuroHub too)

  • Projects can be tagged as 'un-assignable", so that a member
    of the project cannot assign userfiles or tasks or other resources
    to it (except for the project's creator). This is mostly
    useful for projects that represent fixed datasets that are
    meant to be used but not extended further.
  • CBRAIN (and NeuroHub) now creates a single pair of SSH keys
    (one private, one public) for each user that the system can
    use to access external resources. The private key is never
    made visible. Right now this is mostly useful for the new
    UserkeyFlatDirSshDataProvider class in NeuroHub.
  • These keys (full pair) can be pushed to a Bourreau so that
    the CBRAIN code running there can connect as the user. Users
    have control over which bourreau to push their key pair to.
  • CBRAIN can generate a new API token and show it to the user
    in their 'my account' page.
  • When a user accepts an invitation to join a project, the
    person who made the invitation is notified.
  • When an admin reviews a signup request, they can tell
    if the request was made using the CBRAIN or the NeuroHub
    signup page.
  • Users can see how many active sessions they have (including
    API sessions), and from what IP they connected.
  • Admins can set a user's default data provider when creating
    their account.

NeuroHub exclusive features:

  • If a user enters their ORCID ID in their profile, they
    can log in using the ORCID authentication platform.
  • Projects are limited to "Work" projects; the other special
    projects that CBRAIN supplies by default are hidden.
  • Projects can have special members designated as 'editors'.
  • Project editors have much the same powers as the project's creator.
  • A project's creator can assign a license to it; members will
    have to agree to the license before they can access it.
  • Projects can be configured as 'public'. Things assigned to public
    projects can be accessed by any user.
  • User can create their own Data Providers. This is limited right
    now to DPs of type 'UserkeyFlatDirSshDataProvider'. The provider
    side will be accessed using the personal SSH key of the user
    who created the DP. Mostly useful for power users who want to
    access remote filesystems.
  • Specialized API hooks for LORIS integrations. Right now, only
    one such hook is implemented, file_list_maker.

Other:

  • Much code refactoring (e.g. FileInfo class, BrowseProviderFileCaching,
    SshDataProviderBase...).
  • Selection boxes are shown with the chosen.jquery.js framework.
  • DP consistency checkers improved.
