This PR adds `snaps` under Flask build flags to the extension. This branch is mostly equivalent to the current production version of Flask, excepting some bug fixes and tweaks.
Closes#11626
* Update support links for Flask
* Disable 'prefer-const' in code fence linting
* Add bespoke home footer for Flask and update logic
* fixup! Add bespoke home footer for Flask and update logic
* Fix code fence lint failure
* Fix support request link in account menu
* Fix unit test failure
* Prevent automatic rejection of confirmations
Confirmations are now only automatically rejected if a user explicitly
closes the notification window. If we close the window programmatically
because there are no notifications left to show, nothing gets rejected.
This partially avoids a race condition where a confirmation gets
rejected automatically without the user having seen the confirmation
first. This could happen if the confirmation was processed just as the
notification window was being closed.
It's still possible for a confirmation that the user has never seen to
get rejected as a result of the user closing the window. But at least
now it's no longer possible for a confirmation to get rejected in this
manner after the user resolves the last confirmation in the queue.
* Fix bug that prevented automatic closure detection
All windows were being detected as explicit window closures,
essentially just as they were previously, because this variable was
cleared too soon.
* Re-open popup when necessary
After the window is automatically closed, a confirmation may have been
queued up while the window was closing. If so, the popup is now re-
opened.
The `mounted` state was used to derive state from props before the
first render of the Home component. Instead this state is now derived
in the constructor, which is also run before the first render. This
should behave exactly the same, except now we don't need the `mounted`
state or the `deriveStateFromProps` function anymore.
The call to `closeCurrentWindow` that was made in `componentDidUpdate`
has been moved to the constructor as well. There is no need to delay
that call, and this saves us from having to compare current with
previous state in that lifecycle function.
# 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`.
