# 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`.

A propType error was showing up during e2e tests with a `testDev`
build. It was caused by `process.env.IN_TEST` being treated as a
boolean, when in fact it is either the string `'true'` or a boolean.
`IN_TEST` has been updated to always be a boolean. `loose-envify` has
no trouble injecting boolean values, so there's no reason to treat this
as a string.

We're bumping from `^6` to `^8`. All imports are now named, and they have been updated. This is a breaking change, in that support for `eth_signTransaction` is added in `^8.0.0`. We do not support this method in our UI, so our middleware stack has been instrumented to reject.
In addition, there are some non-breaking behavioral changes in this version that reviewers should be aware of, see the [7.0.0 release](https://github.com/MetaMask/eth-json-rpc-middleware/releases).

Adds the latest version of `@metamask/controllers`, and updates our usage of the `ApprovalController`, which has been migrated to `BaseControllerV2`. Of [the new `controllers` release](https://github.com/MetaMask/controllers/releases/tag/v15.0.0), only the `ApprovalController` migration should be breaking.
This is the first time we use events on the `ControllerMessenger` to update the badge, so I turned the messenger into a property on the main `MetaMaskController` in order to subscribe to events on it in `background.js`. I confirmed that the badge does indeed update during local QA.
As it turns out, [MetaMask/controllers#571](https://github.com/MetaMask/controllers/pull/571) was breaking for a single unit test case, which is now handled during setup and teardown for the related test suite (`metamask-controller.test.js`).

* Remove redundant setEstimateToUse call in onManualChange
* Fix unit tests

Only the first parameter, `type`, was ever passed in. The others are
superfluous. The defaults have been set directly instead.
It's a bit silly to set the `rpcUrl` and `nickname` to an empty string,
but to make this more sensible would take much more effort. This at
least is simpler and guaranteed to be equivalent.
* Add stringified payload to metametrics controller trackEvent error message
* Don't include full payload when throwing error on missing event or category in trackEvent
The `assert` module has two modes: "Legacy" and "strict". When using
strict mode, the "strict" version of each assertion method is implied.
Whereas in legacy mode, by default it will use the deprecated, "loose"
version of each assertion.
We now use strict mode everywhere. A few tests required updates where
they were asserting the wrong thing, and it was passing beforehand due
to the loose matching.

Our automatic token detection was hard-coded to only work on our built-
in Infura Mainnet endpoint. It now works with custom Mainnet RPC
endpoints as well.
Relates to #6992
`eth_getProof` is an unpermissioned, read-only RPC method for getting account-related Merkle proofs, specified here: https://eips.ethereum.org/EIPS/eip-1186
It's been supported by major Ethereum clients, and Infura, for some time. By adding it to the safe methods list, we enable this method for our users.
This PR introduces the new approval controller to the extension codebase. We use it for the permissions controller's pending approval functionality.
The approval controller sets us up for a new pattern of requesting and managing user confirmations in RPC methods. Along with the generic RPC method middleware, the approval controller will allow us to eliminate our message managers, and decouple various method handlers from our provider stack, making the implementations more portable between the extension and mobile.
From a behavioral standpoint this PR fixes the issue with tracking, and persisting, tokens that the user hides. Whether we can/should optimize this to prevent duplicates of the accountHiddenTokens and hiddenToken is a point of contention, but it acts similiarly to how we track tokens and accountTokens.
Also to note, for tokens under a custom network there is no way to distinguish two different custom network sets of hidden tokens, they are all under the `rpc` property, same as accountTokens.
