A bug in service comparison would make it that a device already running
a service from a new release with network changes would never stop the
running service so remaining services would forever get stuck in
`Downloaded` state.
This fixes the comparison so the service will get killed in this case,
particularly allowing devices to recover from #1576
Change-type: patch
Devices affected by the bug described in 1576, are also stuck with some
services in the `Downloaded` state, because the state engine does not
detect that the running services should be killed on a network change
even if they belong to a new release. This is a bug, which can be
replicated by the tests in this commit
Change-type: patch
Previous behavior would make it that an `updateMetadata` step would take
precedence over a `kill` step when network changes are present. This
would lead to an inconsistent state if an update included a
network and a container change.
Closes: #1576
Change-type: patch
These tests use the supervisor API to check that applying a target state
allows the device to eventually get to the desired target configuration.
This are high-level tests that work with real images and containers
using dind.
Change-type: patch
The supervisor allows the target image to be an image without a
registry (e.g. `alpine:latest`), while this really only happens while in
local mode, we don't want to pass credentials to the default registry as
those credentials are meant for balena registry and will otherwise fail.

Target volatile doesn't make sense now that we can use the
current state as a target. It wasn't actually being used for anything
anymore apparently
Change-type: patch
This simplifies this module interface and hides implementation details
from the rest of the code.
The function `applyIntermediateTarget` will now call `pausingApply`
before applying the target
API actions no longer need to call pausing apply
Change-type: patch
The actions now work by passing an intermediate state to the state
engine.
- doPurge first removes the user app from the target state and passes
that to the state engine for purging. Since intermediate state doesn't
remove images, this will have the effect of basically re-installing
the app.
- doRestart modifies the target state by first removing only the
services from the current state but keeping volumes and networks. This
has the same effect as before where services were stopped one by one
Change-type: patch
Local mode uses a numeric `appUuid` which was messing up parsing the
network name. This fixes this issue so the current state can be used
as a target state
Change-type: patch
The Service class in `compose/service.ts` cannot get the image name
from the image id when building the object from the container metadata.
We query the metadata in the application manager getCurrentApps method
so the current state can be used as target by API methods
Change-type: patch
Network aliases are now compared checking that the target state is a
subset of the current state. This will prevent service restarts due to
additional aliases created by docker in the container.
Closes: #2134
Change-type: patch
When getting the service from the docker container, remove the
containerId from the list of aliases (which gets added by docker). This
will make it easier to use the current service state as a target.
This will help us remove the `safeStateClone` function in the API in a
future commit
Change-type: patch
This replaces the previous flag `isApplyingIntermediate` on application
manager and simplifies the interface of the state engine to make temporary changes to the
general app state.
Change-type: patch
There were multiple places in the state engine that skipped some
operations while in local mode. In reality, all it's needed while in
local mode is to skip image and volume deletion.
This commit simplifies application-manager and compose app to be more
local mode agnostic and instead making the image deletion and volume
deletion configurable via function arguments.
This also has the benefit to make the treatment of local mode
applications more similar to cloud mode applications, allowing for
API endpoints to function the same way both modes.
Change-type: patch
The OS since v2.82.6 will monitor changes to config.json and restart
the relevant services to apply the changes. There is no need to trigger
restart of the services via the supervisor. Users on older OS versions
will need to update their OS or restart the services manually as OS
loses support after 2y.
Change-type: patch
Closes: #2160
We don't need this anonymous volume as /data is bind mounted into
the container from host (legacy), and will soon be mounted by the
Supervisor itself on startup.

Node 15 [changed the way it treats unhandled promise rejections](https://github.com/nodejs/node/blob/main/doc/changelogs/CHANGELOG_V15.md#throw-on-unhandled-rejections---33021) from a warning to a throw.
For this reason errors like a corrupt migration directory, that happens when trying to
roll back to a previous supervisor version were no longer showing a
message but dumping the full minimized code into the journal logs.
This PR adds a catchall on app.ts to log the exception and throw an exit
code of 1.

Restart-service checks that both services have restarted in its test assertion, which is
incorrect as restart-service should only restart one service.

As the Supervisor is a privileged container, it has access to host /dev, and therefore has access
to boot, data, and state balenaOS partitions. This commit sets up the framework for the following:
- Finds the /dev partition that corresponds to each partition based on partition label
- Mounts the partitions into set mountpoints in the device
- Removes reliance on env vars and mountpoints provided by host's start-balena-supervisor script
- Simplifies host path querying by centralizing these queries through methods in lib/host-utils.ts
This particular changes env vars for and mounts the boot partition.
Since the Supervisor would no longer rely on container `run` arguments provided by a host script,
this change moves Supervisor closer to being able to start itself (Supervisor-as-an-app).

This reverts commit 00e389e5f5.
Images generated using this dockerfile still don't have the right
architecture. More testing is needed
