# Permission System 2.0
## Background
This PR migrates the extension permission system to [the new `PermissionController`](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions).
The original permission system, based on [`rpc-cap`](https://github.com/MetaMask/rpc-cap), introduced [`ZCAP-LD`](https://w3c-ccg.github.io/zcap-ld/)-like permissions to our JSON-RPC stack.
We used it to [implement](https://github.com/MetaMask/metamask-extension/pull/7004) what we called "LoginPerSite" in [version 7.7.0](https://github.com/MetaMask/metamask-extension/releases/tag/v7.7.0) of the extension, which enabled the user to choose which accounts, if any, should be exposed to each dapp.
While that was a worthwhile feature in and of itself, we wanted a permission _system_ in order to enable everything we are going to with Snaps.
Unfortunately, the original permission system was difficult to use, and necessitated the creation of the original `PermissionsController` (note the "s"), which was more or less a wrapper for `rpc-cap`.
With this PR, we shake off the yoke of the original permission system, in favor of the modular, self-contained, ergonomic, and more mature permission system 2.0.
Note that [the `PermissionController` readme](https://github.com/MetaMask/snaps-skunkworks/tree/main/packages/controllers/src/permissions/README.md) explains how the new permission system works.
The `PermissionController` and `SubjectMetadataController` are currently shipped via `@metamask/snap-controllers`. This is a temporary state of affairs, and we'll move them to `@metamask/controllers` once they've landed in prod.
## Changes in Detail
First, the changes in this PR are not as big as they seem. Roughly half of the additions in this PR are fixtures in the test for the new migration (number 68), and a significant portion of the remaining ~2500 lines are due to find-and-replace changes in other test fixtures and UI files.
- The extension `PermissionsController` has been deleted, and completely replaced with the new `PermissionController` from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers).
- The original `PermissionsController` "domain metadata" functionality is now managed by the new `SubjectMetadataController`, also from [`@metamask/snap-controllers`](https://www.npmjs.com/package/@metamask/snap-controllers).
- The permission activity and history log controller has been renamed `PermissionLogController` and has its own top-level state key, but is otherwise functionally equivalent to the existing implementation.
- Migration number 68 has been added to account for the new state changes.
- The tests in `app/scripts/controllers/permissions` have been migrated from `mocha` to `jest`.
Reviewers should focus their attention on the following files:
- `app/scripts/`
- `metamask-controller.js`
- This is where most of the integration work for the new `PermissionController` occurs.
Some functions that were internal to the original controller were moved here.
- `controllers/permissions/`
- `selectors.js`
- These selectors are for `ControllerMessenger` selector subscriptions. The actual subscriptions occur in `metamask-controller.js`. See the `ControllerMessenger` implementation for details.
- `specifications.js`
- The caveat and permission specifications are required by the new `PermissionController`, and are used to specify the `eth_accounts` permission and its JSON-RPC method implementation.
See the `PermissionController` readme for details.
- `migrations/068.js`
- The new state should be cross-referenced with the controllers that manage it.
The accompanying tests should also be thoroughly reviewed.
Some files may appear new but have just moved and/or been renamed:
- `app/scripts/lib/rpc-method-middleware/handlers/request-accounts.js`
- This was previously implemented in `controllers/permissions/permissionsMethodMiddleware.js`.
- `test/mocks/permissions.js`
- A truncated version of `test/mocks/permission-controller.js`.

`improved-yarn-audit` has been updated so that it supports GitHub
advisories. Two new GitHub advisories have been ignored, as they are
both moderate RegExp DoS vulnerabilities that don't affect us, and they
are embedded deep within our dependency graph and are difficult to
update.
The beta and Flask builds are now built on CI and included in the
metamask bot comment alongside the main builds. The same sourcemap
linter and mozilla linter used for the prod builds is also run on the
beta and Flask builds.
Closes#12426
There are a few issues encountered when running `yarn setup` on new
Apple Silicon (aka M1, aka arm64) Macs:
* The script halts when attempting to run the install step for
the `chromedriver` package with the message "Only Mac 64 bits
supported". This is somewhat misleading as it seems to indicate that
chromedriver can only be installed on a 64-bit Mac. However, what I
think is happening is that the installation script for `chromedriver`
is not able to detect that an arm64 CPU *is* a 64-bit CPU. After
looking through the `chromedriver` repo, it appears that 87.0.1 is the
first version that adds a proper check ([1]).
Note that upgrading chromedriver caused the Chrome-specific tests to
fail intermittently on CI. I was not able to 100% work out the reason
for this, but ensuring that X (which provides a way for Chrome to run
in a GUI setting from the command line) is available seems to fix
these issues.
* The script also halts when attempting to run the install step for
the `electron` package. This happens because for the version of
`electron` we are using (9.4.2), there is no available binary for
arm64. It appears that Electron 11.x was the first version to support
arm64 Macs ([2]). This is a bit trickier to resolve because we don't
explicitly rely on `electron` — that's brought in by `react-devtools`.
The first version of `react-devtools` that relies on `electron` 11.x
is 4.11.0 ([3]).

The benchmark script can now be set to retry upon failure, like the E2E
tests do. The default is zero, just as with the E2E tests. A retry of 2
has been set in CI to match the E2E tests as well.
The `retry` module had to be adjusted to throw an error in the case of
failure. Previously it just set the exit code, but that only worked
because it was the last thing called before the process ended. That is
no longer the case.
This script makes it easier to run an individual E2E test. In the past
I've run individual scripts by editing `run-all.sh` manually, but now
that can be done more easily with this script. It also allows setting
the number of retries to use and the browser to use from the CLI.
This script has been added as an npm script as well, called
'test:e2e:single'.
The `run-all.sh` script was rewritten in JavaScript to make it easier
to pass through a `--retries` argument.
The default number of retries has been set to zero to make local
testing easier. It has been set to 2 on CI.
This was mainly done to consolidate the code used to run an E2E test in
one place, to make later improvements easier.
Sentry is now configured with environment variables, rather than with
hard-coded values. This makes it easier to test Sentry functionality
using a different Sentry account, as we did recently during QA of
v9.5.1.
The only change for the normal build process is the introduction of the
`SENTRY_DSN_DEV` variable, which can be set via `.metamaskrc` or via an
environment variable. This determines where error reports are sent. It
still defaults to our team Sentry account's `metamask-testing` project.
The `sentry:publish` script now requires SENTRY_ORG and SENTRY_PROJECT
to be set in order to publish release artifacts. The CircleCI
configuration has been updated with these values, so it should act the
same as it did before. Previously we had used a CLI flag to specify the
organization and project, but Sentry already natively supports these
environment variables [1].

The version field is now stored in the main `package.json` file rather
than in the base manifest. It is built into the final manifest during
the build script.
This makes it easier to communicate what the current version should be
to our `auto-changelog` script. It's also generally a more conventional
place to keep track of the version, even considering that we're not
publishing to npm.
Add changelog validation to CI, ensuring that the changelog follows the
KeepAChangelog format. Additionally, this will also ensure that all of
the auto-generated "Uncategorized" changelog entries on release
branches get categorized.
The check for the GITHUB_TOKEN environment variable was being done in
the wrong release script. It has been migrated to the relevant script.
A second check for the username has also been added, as it is also
required.
The SSH key used for Storybook deployments to `metamask-storybook` has
been updated. This new key is associated with `metamaskbot` rather than
a specific team member.

The changelog script now accepts an `--rc` flag to tell it whether to
add new changes to `Unreleased` or to the header for the current
version.
Previously this was inferred from whether the current version matched
the most recent tag. However this method only works for the first
update. Using a flag simplifies this logic, and makes it possible to
manually re-run this for further updates to a release candidate.
The changelog will now be automatically updated when a release branch
is created. A new release header along with changelog entries for any
new commits will be added.
Note that this changelog will still need to be manually cleaned up, but
it's one less manual step at least.
The old Bash script for adding a new release header to the changelog
has been removed, as that functionality is now built into the changelog
update script.
A new script has been added to commit any changes made to the manifest
and changelog. This step used to happen at the end of the bump manifest
version script, but now the changelog update relies upon the manifest
version bump happening first, so it needed to be re-ordered. The
changes should only be committed on the first run of the branch, as
it's contingent upon the manifest changing (due to the version bump).
Further changelog updates won't trigger new automatic commits.
The script responsible for creating the "Sync `master` with `develop`"
PR has been removed. We will soon be eliminating the need for a
`master` branch altogether, so we don't need this anymore. Also, this
script hasn't been running correctly in a long time. We've been
creating this PR manually.
New changelog release headers now omit the date. These headers are
added automatically when a new release branch is created, and that
rarely ends up being the actual date of the release, so these dates
have all been inaccurate anyway.
The date will be re-added to the changelog later as part of a new
script, after a release has been published.
The CI script to ensure no LavaMoat policy changes are required has
been failing despite there being no changes. It turns out that the
command used to check for changes (`git diff-index`) was failing
despite the lack of changes because the file was written again by
`yarn lavamoat:auto` but git hadn't gotten around to updating its index
since the write occurred, so it was considering it as changed until it
verified it wasn't [1].
The command has been replaced by `git diff --exit-code --quiet`, which
should do exactly the same thing except that it forces git to update
its internal cache to verify whether changes are present.

A CI job has been added to ensure the `allow-scripts` config and the
LavaMoat auto-generated policy is up-to-date. This will only run on
release branches and the `master` branch, because it's too difficult a
requirement to meet for each PR for contributors on macOS, due to
differences in the dependency graph caused by optional dependencies.
The `allow-scripts` and LavaMoat policy have both been updated using
`yarn allow-scripts auto` and `yarn lavamoat:auto`.
The `.sh` file extension is now used for all Bash scripts. This ensures
the files are recognized as Bash scripts by the ShellCheck CI job, and
by editors/IDEs for improved syntax highlighting.

Dependencies are now cached between builds, using a checksum of the
`yarn.lock` file as the cache key. The `node_modules` directory and the
`.har` file from the install are cached and restored, so that we ensure
the record of the install is always preserved alongside the
dependencies.
The consolidation of the `collect-har-artifact` script was to make it
easier to cache the `.har` file along with the dependencies.
We don't look at coveralls very much. We might occasionally consult it
to see a report on our code coverage, but that report is already
generated entirely locally, and has been added to the MetaMask bot
comment in #10061.
