From 59b386526a6cdd0289cdf35dd8038ae1bdfd630f Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 3 Dec 2014 22:46:48 -0500 Subject: credential: let helpers tell us to quit When we are trying to fill a credential, we loop over the set of defined credential-helpers, then fall back to running askpass, and then finally prompt on the terminal. Helpers which cannot find a credential are free to tell us nothing, but they cannot currently ask us to stop prompting. This patch lets them provide a "quit" attribute, which asks us to stop the process entirely (avoiding running more helpers, as well as the askpass/terminal prompt). This has a few possible uses: 1. A helper which prompts the user itself (e.g., in a dialog) can provide a "cancel" button to the user to stop further prompts. 2. Some helpers may know that prompting cannot possibly work. For example, if their role is to broker a ticket from an external auth system and that auth system cannot be contacted, there is no point in continuing (we need a ticket to authenticate, and the user cannot provide one by typing it in).
