From 5e380138e7fa45997565cdcec51e913c471db431 Mon Sep 17 00:00:00 2001 From: Daniel Mueller Date: Mon, 12 Aug 2019 22:23:33 -0700 Subject: Update nitrokey crate to 0.4.0-alpha.3 This change updates the version of the nitrokey crate that we use to 0.4.0-alpha.3. This version is the supposedly last pre-release before 0.4.0, with no further major anticipated changes. In order to integrate with this new version we have to adjust the way we connect to a Nitrokey device by funneling those connection requests through a global manager object. The rationale behind that step being that the underlying libnitrokey actually cannot handle access of multiple devices at the same time, and so the manager object is used to prevent accidental wrong concurrent usage. Because a device object now effectively keeps a reference to the manager, we need to provide an additional lifetime to that and derived objects. Lastly, the use of a manager is also the reason why the tests had to be adjusted to no longer accept device objects in their signatures, but only the respective model for which to invoke the test. That is required because, as elaborated earlier on, having a device object implies having taken a reference to a manager (in that case owned by nitrokey-test), and that reference clashes with the nitrocli code itself attempting to take the manager. We side step this problem by merely accepting a Model object, which can be passed around independently of the manager itself, meaning that nitrokey-test does not need to hold such a reference while the test is run.
