In Hudson a Tab is known as a View.

• • • Issue 3945 has been marked as a duplicate of this issue. ***

I've closed 2 requests for setting view permissions in favor of this request..
use the project permissions to control what can be seen, and the UI should just
hide those view tabs where the current user can't see any of the projects.
We'll need to figure out when to show a tab even when empty though.. maybe
admins always see all views, or anyone who can edit a view always sees it.. that
way someone can find the view to add projects or delete it.

This works by simply wrapping each <l:tab> inside this condition in View/main.jelly:
<j:if test="${v==it or v.hasPermission(v.CONFIGURE) or !empty(v.items)}">

however, this calls View.getItems() on every view every time a view page is shown. should there be a short-term cache to avoid recomputation?

Any update on this issue?

Same problem here. We would like to reduce the size of the view tab bar and use project-based security as well. Anything new regarding this issue?

just placed a pull request: https://github.com/jenkinsci/jenkins/pull/370

thanks for the pull request. I am scheduling an update session as soon as it is merged to jenkins:master.

[FIXED JENKINS-3681] Added View.READ permission.

The trick for backward compatibility is in the default implementation
that grants View.READ to those who have access to items.

This change introduces a small side effect. I use Sectioned View plugin to create a view, which does not contain projects, but informative content in textual format like FAQs, announcements, etc. With this change, this "info view" became unavailable for end users.

As a workaround I added a List View section with one project to the bottom of the view. I also removed all columns from the section. This leaves two empty bars at the end of the view. It does not look pretty, but at least the view is visible to end users again.

Jenkins version is 1.460.
