`@metamask/eslint-config` has been updated to v4.1.0. This update
requires that we update `eslint` to v7 as well, which in turn requires
updating most `eslint`-related packages.
Most notably, `babel-eslint` was replaced with `@babel/eslint-parser`,
and `babel-eslint-plugin` was replaced by `@babel/eslint-plugin`. This
required renaming all the `babel/*` rules to `@babel/*`.
Most new or updated rules that resulted in lint errors have been
temporarily disabled. They will be fixed and re-enabled in subsequent
PRs.

When the `chainId` for a custom RPC endpoint is edited, we now migrate
the corresponding address book entries to ensure they are not orphaned.
The address book entries are grouped by the `metamask.network` state,
which unfortunately was sometimes the `chainId`, and sometimes the
`networkId`. It was always the `networkId` for built-in Infura
networks, but for custom RPC endpoints it would be set to the user-set
`chainId` field, with a fallback to the `networkId` of the network.
A recent change will force users to enter valid `chainId`s on all
custom networks, which will be normalized to be hex-prefixed. As a
result, address book contacts will now be keyed by a different string.
The contact entries are now migrated when this edit takes place.
There are some edge cases where two separate entries share the same set
of contacts. For example, if two entries have the same `chainId`, or if
they had the same `networkId` and had no `chainId` set. When the
`chainId` is edited in such cases, the contacts are duplicated on both
networks. This is the best we can do, as we don't have any way to know
which network the contacts _should_ be on.
The `typed-message-manager` unit tests have also been updated as part
of this commit because the addition of `sinon.restore()` to the
preferences controller tests ended up clearing a test object in-between
individual tests in that file. The test object is now re-constructed
before each individual test.

JSON files are now sorted by key with `prettier`, using the plugin
`prettier-plugin-sort-json`. This does not affect `package.json`
because `prettier` uses a special parser for that file, as it has
a more restrictive format than JSON.
Instead of using `eslint-plugin-json` for linting JSON files,
`prettier` is now used. `prettier` is capable of detecting and
correcting more problems than `eslint-plugin-json` can, such as
indentation.
All JSON files have been run through `prettier`. The changes are all
superficial.
* Use verifyPassword instead of submitPassword when exporting priv key

* Fix require-unicode-regexp issues
See [`require-unicode-regexp`](https://eslint.org/docs/rules/require-unicode-regexp) for more information.
This change enables `require-unicode-regexp` and fixes the issues raised by the rule.
* Remove case-insensitive flag from regexps
This change fixes the `_validateERC20AssetParams` tests, ensuring that the given
options are all valid except those that are being tested. Previously the `symbol`
property was invalid _in addition to_ the `decimals` property.
This one gets a bit more complicated because the styles were interwoven and needed to be untangled to be moved. Essentially, though, the goal is to put the styles where they make the most sense and colocate them with their components.
This migration had referred to the non-existent
`TransactionsController` instead of `TransactionController`, so it
effectively did nothing. Now it should work.
This migration hasn't been included in any release yet, so we can fix
it in-place instead of adding an additional corrected migration.
The migration comment has also been updated, as it was inaccurate.
The remaining integration tests are all covered by e2e tests, so
they're no longer needed.
All associated scripts, fixtures, and dependencies have also been
removed.
This tests the `personal_sign` method using the test dapp. This test
reflects part of the `confirm-sig-requests` integration test, which
tests the confirmation of a `personal_sign` signature request.
A `data-testid` prop was added to the 'Sign' button on the signature
request confirmation page, to make it easier to select the 'Sign'
button reliably.
This updated test dapp has a new `personal_sign` button. It also fixes
the `Encrypt` button, which was broken in `v3.0.0`.
The `signature-request` e2e test needed to be updated to find the
'Sign' button by id rather than by text, since there are now two
buttons with the text 'Sign'.
The `withFixtures` helper function now has the option of starting the
test dapp as well. It will wait to ensure it has started up correctly,
and it'll shut it down when the test ends.
This test mirrors the `localization` integration test. It only tests
the display of fiat currency on the home page, and it only tests one
currency (`php`).
Both the primary and secondary balance components on `EthOverview` now
have `data-testid` props, so that they can be more easily referenced in
e2e tests.
This required the addition of a `data-testid` prop to the component
`UserPreferencedCurrencyDisplay`, which is passed through to the
underlying `CurrencyDisplay` component.
The e2e test helper function `withFixtures` now includes verbose
reporting on failure. Whenever a test fails, debugging information will
be saved to disk, just as with the other e2e test modules.
e2e test that use the `withFixtures` helper now check for console
errors after each successful test. If any errors are found, the test
fails.
It's currently enabled for Chrome only, because the Firefox driver
throws an error when you attempt to get the browser logs. Not sure why
exactly, but it's a long-standing problem.
The webdriver method `verboseReportOnFailure` had previously taken a
single parameter, `test`, which was an object representing the current
Mocha test. However, only one property was used (`title`).
Instead the `title` is now passed through directly. This was done to
make this function easier to use outside of a Mocha context.
It seems that this blocklist checker never worked correctly. Ever since
the initial commit, it was comparing the Number `1` to the `networkId`,
which is a string. Additionally, even if it did throw, the transaction
continued unhindered. The user could still approve it, and there was no
indication shown to the user that anything went wrong. Also some of the
blocklist entries were incorrectly mixed-case, and were never hit.
We can remove this for now, and re-add it later on after we rewrite the
transaction controller.
The `metamaskNetworkId` property in the `txMeta` for incoming
transactions was incorrectly set as a Number instead of a String. This
change was made accidentally as part of #8627.
As a result incoming transactions were being excluded from the
transaction list, as they didn't have a matching network ID.
`metamaskNetworkId` is now set to a string, and a migration has been
added to ensure `metamaskNetworkId` is converted to a string for any
incoming transactions in state.
The 'Expand view' button in the 'Account Options' menu was still being
shown on the fullscreen UI. This button is not useful in fullscreen, as
all it does is open the fullscreen UI. It is now hidden on the
fullscreen UI.
Imported accounts can be removed, but the permissions controller is not
informed when this happens. Permissions are now removed as part of the
account removal process.
Additionally, the `getPermittedIdentitiesForCurrentTab` selector now
filters out any non-existent accounts, in case a render occurs in the
middle of an account removal.
This was resulting in a render crash upon opening the popup on a site
that was connected to the removed account.
'Activity' is a better name for this tab because it contains more than
just transactions. Signature requests are also included, and more non-
transaction activity may be included in the future.
The `TokenRatesController` was accidentally broken in #8744, when the
logic for starting and stopping polling was moved from the `isActive`
property to start/stop functions.
A reference to the now-obsolete `isActive` property was accidentally
left behind, resulting in no exchange rate updates.
The entry for imported accounts in the account menu looked wrong with
the new connected site icon - there was no padding between the site
icon and the 'imported' label. The entry was pretty crowded with these
three symbols as well (the third being the 'x' used to remove the
account).
The site icon has been made the right-most icon, so that it lines up
with the site icons shown for other accounts, and spacing has been
added between the site icon and the 'imported' label.
The 'x' used to remove accounts has been removed. Accounts can still be
removed from the 'Account Options' menu on the Home screen. This seemed
like the wrong place for this button to exist, as it's the only action
that can be taken from that menu aside from navigation.
* refactor asset items to use list-item
Refactors the asset-list-item and token-cell to rely on the list-item
component for UI. Little changes were needed to the list-item code
to make this work! The result should be lots of eliminated code
Co-authored-by: Mark Stacey <markjstacey@gmail.com>
The "the transaction has the expected gas price" test was assuming the
fifth element with the `transaction-breakdown__value` class was the
element with the gas price. In practice that was sometimes not the
case, because some transaction detail fields would not be present, or
would appear after the first render.
The field is now looked up with a test id, ensuring it always finds the
correct field.
The e2e test for the "Hide token" functionality was incorrectly
clicking "Cancel" on the "Hide token" modal, thus not actually testing
that that token was hidden at all.
The "Confirm" button is now selected using a test id, to ensure the
wrong button isn't selected.
A new page has been created for viewing assets. This replaces the old
`selectedToken` state, which previously would augment the home page
to show token-specific information.
The new asset page shows the standard token overview as seen previously
on the home page, plus a history filtered to show just transactions
relevant to that token.
The actions that were available in the old token list menu have been
moved to a "Token Options" menu that mirrors the "Account Options"
menu.
The `selectedTokenAddress` state has been removed, as it is no longer
being used for anything.
`getMetaMetricState` has been renamed to `getBackgroundMetaMetricState`
because its sole purpose is extracting data from the background state
to send metrics from the background. It's not really a selector, but
it was convenient for it to use the same selectors the UI uses to
extract background data, so I left it there for now.
A new Redux store has been added to track state related to browser history.
The most recent "overview" page (i.e. the home page or the asset page) is
currently being tracked, so that actions taken from the asset page can return
the user back to the asset page when the action has finished.
The fullscreen UI now shows roughly the same design as the popup UI.
A few additional changes depicted in the new fullscreen designs will
be implemented in subsequent PRs (e.g. the inline buttons on assets)
This was done now to make asset pages easier to implement. Implementing
asset pages solely for the popup UI would have been complicated by the
fact that we use viewport size to switch between the two layouts, so we
would have had to re-route upon resizing the window.
The `AccountDetailsDropdown` component has been rewritten to use the
new `Menu` component, and to follow the latest designs.
This should be functionally equivalent. A couple of the icons have
changed, but that's about it.
Support for a subtitle was added to `MenuItem` to support the `origin`
subtitle used for the explorer link for custom RPC endpoints.
A few adjustments were required to `test/helper.js` to accommodate
the use of `Menu` from a JSDOM context (this is the first time it's
been used in a unit test). A `popover-content` element was added to the
fake DOM, and another global was added that `react-popper` used
internally.
An additional driver method (`clickPoint`) was added to the e2e driver
to allow clicking the background behind the menu to dismiss it. This
wasn't possible using the `clickElement` method, because that method
would refuse to click an obscured element. The only non-obscured
element to click was the menu backdrop, and that didn't work either
because the center was obscured by the menu (Selenium clicks the center
of whichever element is targeted).
The `TransactionViewBalance` component has been split into three
separate components. This was done primarily to make the asset page
easier to implement. Also the name `TransactionViewBalance` didn't
describe this component very well anymore.
Instead of the Ethereum and token-specific logic being in the same
component, the two cases were split into the `EthOverview` and
`TokenOverview` components respectively. They both use the
`WalletOverview` component, which has the structure shared by both
cases.
CSF = Storybook’s Component Story Format (CSF)
See https://storybook.js.org/docs/formats/component-story-format/
Note that the migrations still use CommonJS require, so the default export as
an object is quite ergonomic (& I don't want to touch the migrations).
What
- modify `ui/app/helpers/utils/transactions.util.js` and
`ui/lib/account-link.js` to strip trailing slashes
if they are present.
- added relevant tests not just for the new scenario,
but also the general scenarios for these functions,
as there previously was no test coverage for these
two functions.
Why
- Current behaviour, when user enters a block explorer URL
when configuring a custom RPC, and that block explorer URL
contains a trailing `/`.
- e.g. `https://block.explorer/`
- this results in a double-slash (`//`) in the transaction
and account URLs generated by MetaMask.
- e.g. `https://block.explorer/tx/0xabcd...`,
`https://block.explorer/account/0xabcd...`
- This needs to be handled using a router redirect
on the server of the block explorer,
and this changes would avoid that requirement.
All asset list items now use the same component (`AssetListItem`).
Previously the tokens and the Ethereum balance were totally separate
components, despite being styled similarly.
Various unnecessary DOM elements and style rules were removed, but the
overall list looks identical to how it looked before.
Add alert suggesting that the user switch to a connected account. This
alert is displayed when the popup is opened over an active tab that is
connected to some account, but not the current selected account. The
user can choose to switch to a connected account, or dismiss the alert.
This alert is only shown once per account switch. So if the user
repeatedly opens the popup on a dapp without switching accounts, it'll
only be shown the first time. The alert also won't be shown if the user
has just dismissed an "Unconnected account" alert on this same dapp
and account, as that would be redundant.
The alert has a "Don't show me this again" checkbox that allows the
user to disable the alert. It can be re-enabled again on the Alerts
settings page.
The unconnected account alert can now be disabled. A "don't show this
again" checkbox has been added to the alert, which prevents that alert
from being shown in the future.
An alert settings page has been added to the settings as well. This
page allows the user to disable or enable any alert.
This controller was not used. It was used by the
`ComputedBalancesController`, which was removed in #7057 (as it was
also unused).
The pending balances calculator was only used by the balances
controller.
A race condition exists where after adding an unapproved transaction,
it could be mutated and then replaced when the default gas parameters
are set. This happens because the transaction is added to state and
broadcast before the default gas parameters are set, because
calculating the default gas parameters to use takes some time.
Once they've been calculated, the false assumption was made that the
transaction hadn't changed.
The method responsible for setting the default gas now retrieves an
up-to-date copy of `txMeta`, and conditionally sets the defaults only
if they haven't yet been set.
This race condition was introduced in #2962, though that PR also added
a loading screen that avoided this issue by preventing the user from
interacting with the transaction until after the gas had been
estimated. Unfortunately this loading screen was not carried forward to
the new UI.
* Remove `estimatedGas` property from `txMeta`
The `estimatedGas` property was a cache of the gas value estimated for
a transaction when the default gas limit was set. This property wasn't
used anywhere. It may have been useful for debugging purposes, but the
same gas estimate is already stored on the `history` property so it
should be present in state logs regardless.
* Remove `gasLimitSpecified` txMeta property
The `gasLimitSpecified` property of `txMeta` wasn't used for anything.
It might have been useful for debugging purposes, but whether or not
the gas limit was specified can also be determined from looking at the
transaction history, so it's not a huge loss.
* Remove `gasPriceSpecified` txMeta property
The `gasPriceSpecified` property of `txMeta` wasn't used for anything.
It might have been useful for debugging purposes, but whether or not
the gas price was specified can also be determined from looking at the
transaction history, so it's not a huge loss.
* Remove `simpleSend` txMeta property
The `simpleSend` property of `txMeta` was used to ensure a buffer was
not added to the gas limit during gas estimation for simple send
transactions. It was made redundant by #8484, which accomplishes this
without the use of this property.
Previously a transaction would get assigned a default value during the
`addTxGasDefaults` function, after the transaction was added and sent
to the UI.
Instead the transaction is assigned a default value before it gets
added. This flow is simpler to follow, and it avoids the race condition
where the transaction is assigned a value from the UI before this
default is set. In that situation, the UI-assigned value would be
overridden, which is obviously not desired.
The test for receiving ETH from a contract had been clicking on the
first transaction list item, assuming it was pending. This is not
necessarily true; if the pending transaction hadn't yet been rendered,
this could select the first confirmed transaction instead.
The test has been updated to look for the first _pending_ transaction,
rather than just the first transaction.
Note that this likely does not fix the intermittent failure we've been
experiencing. The failure has been observed with this fix in place.
This test would occasionally fail due to a fluke of timing, where a
pending transaction would take slightly longer than expected to
be rendered in the "confirmed transactions" list. This `wait` block
ensures the test will try again until it has confirmed.
The test artifact directory for failed test "verbose reports" was
mistakenly being set to `[browser]/undefined`. This was broken during
the refactor in #7798, when the `driver` parameter was mistakenly left
in after the `verboseReportOnFailure` function was converted to a
method being called on `driver`.
An alert is now shown when the user switches from an account that is
connected to the active tab to an account that is not connected. The
alert prompts the user to dismiss the alert or connect the account
they're switching to.
The "loading" state is handled by disabling the buttons, and the error
state is handled by displaying a generic error message and disabling
the connect button.
The new reducer for this alert has been created with `createSlice` from
the Redux Toolkit. This utility is recommended by the Redux team, and
represents a new style of writing reducers that I hope we will use more
in the future (or at least something similar). `createSlice` constructs
a reducer, actions, and action creators automatically. The reducer is
constructed using their `createReducer` helper, which uses Immer to
allow directly mutating the state in the reducer but exposing these
changes as immutable.
`addToAddressBook` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
The callers of this action creator were updated to `await` the
completion of the operation. It was called just before redirecting the
user to a different page or closing a modal, and it seemed appropriate
to wait before doing those things.
The `getSelectedAddress` selector has a fallback of selecting the first
MetaMask account. This is not useful. The only time the
`selectedAddress` is not set is during onboarding, before any accounts
exist, so selecting the first account wouldn't be useful anyway.

`setRpcTarget` returned a thunk that didn't return a Promise, despite
doing async work. It now returns a Promise.
The callers of this action creator didn't need to be updated, as they
were all in event handlers that didn't require knowing when the
operation had completed.
Changes to the background state were being detected in the `update`
event handler in `ui/index.js` that receives state updates from the
background. However this doesn't catch every update; some state
changes are received by the UI in-between these `update` events.
The background `getState` function is callable directly from the UI,
and many action creators call it via `forceUpdateMetamaskState` to
update the `metamask` state immediately without waiting for the next
`update` event. These state updates skip this change detection in
`ui/index.js`.
For example, if a 3Box state restoration resulted in a `currentLocale`
change, and then a `forceUpdateMetamaskState` call completed before the
next `update `event was received, then `updateCurrentLocale` wouldn't
be called, and the `locale` store would not be updated correctly with
the localized messages for the new locale.
We now check for background state changes in the `updateMetamaskState`
action creator. All `metamask` state updates go through this function,
so we aren't missing any changes anymore.
`setProviderType` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
None of the callers of this action creator needed to know when it
completed, so no changes to the call sites were made.
A simple default store of `{ metamask: {} }` is now used for the
actions tests.
While I would prefer that any expectations about the store be included
in each test, the mere existence of this `metamask` object seems like
a fairly reasonable default, as it's (hopefully) impossible for it to
be unset at runtime.
The `2-state.json` test state file was deleted as well, as it was no
longer used.
Many of the "message manager" background methods return a full copy of
the background state in their response; presumably to save us from
making a full round-trip to update the UI `metamask` state after it
changes. However, the action creators responsible for calling these
methods were calling `updateMetamaskState` even when the background
method failed. In effect, they were setting the UI `metamask` state to
`undefined`.
They have been updated to only set the UI `metamask` state if the
background method succeeded.
`setSelectedAddress` returned a thunk that didn't return a Promise,
despite doing async work. It now returns a Promise.
This action creator was only called in two places, and neither benefit
from using the Promise now returned. They were both event handlers. In
both cases there was an existing Promise chain, but the only thing
after this set was a `catch` block that displayed any error
encountered. I decided not to return the result of `setSelectedAddress`
to this chain, because all it would do is set the warning a second
time in the event of failure.
`showAccountDetail` returned a thunk that didn't return a Promise,
despite doing async work. Now it returns a Promise.
This action is only called in one place, and it looks like the actions
dispatched alongside it were meant to be run in parallel, so no changes
were made there.
The `shift-list-item` component for displaying ShapeShift transactions
has been removed, along with three other components that were used
solely by that component (`copyButton`, `eth-balance`, and
`fiat-value`).
This component hasn't been used in some time, as ShapeShift
transactions no longer exist to display. The controller that ShapeShift
transactions originated from was removed in #8118, and it became
impossible to create new ShapeShift transactions from within MetaMask
in #6746
This state has been removed from the background. It was used for the
old UI, and has been unused for some time. A migration has been added
to delete this state as well.
The action creator responsible for updating this state has been removed
from the UI as well, along with the `callBackgroundThenUpdateNoSpinner`
convenience function, which was only used for this action.
The `transForward` app state is no longer used, so it has been removed.
Associated actions have been removed as well.
This state dates back a few years, so I was unable to determine when it
was made obsolete.
Keyrings are added either through the `getKeyringForDevice` background
method (as part of the hardware wallet connect flow), or via
`importAccountWithStrategy` (when importing an account). The
`addNewKeyring` action and corresponding background method has not been
used in a long time.
This state hasn't been used since #5886. The nonce we display in our UI
is now from the background, rather than queried directly from the
front-end.
This also means we save making this network call each time a pending
transaction is added, and each time the transaction list is mounted.
Some of the unit tests for `actions.js` were calling async actions
without `await`-ing them. All async actions are now called with `await`
to ensure they've completed.
`markPasswordForgotten` is an asynchronous function, but it was being
called synchronously. The page was redirected without waiting for the
operation to complete.
We now wait for the operation to complete before continuing. Failure is
still not being handled correctly, but that will be addressed in a
separate PR.

This method adds the given account to the given origin's list of
exposed accounts. This method is not yet used, but it will be in
subsequent PRs (e.g. #8312)
This method has been added to the background API, and a wrapper action
creator has been written as well.
Now that identities are available synchronously in the permissions
controller, accounts can be validated synchronously as well. Any
account the user wants to give permissions to should already be tracked
as an identity in the preferences controller.
* Fix order of accounts in `eth_accounts` response
The accounts returned by `eth_accounts` were in a fixed order - the
order in which the keyring returned them - rather than ordered with the
selected account first. The accounts returned by the `accountsChanged`
event were ordered with the selected account first, but the same order
wasn't used for `eth_accounts`.
We needed to store additional state in order to determine the correct
account order correctly on all dapps. We had only been storing the
current selected account, but since we also need to determine the
primary account per dapp (i.e. the last "selected" account among the
accounts exposed to that dapp), that wasn't enough.
A `lastSelected` property has been added to each identity in the
preferences controller to keep track of the last selected time. This
property is set to the current time (in milliseconds) whenever a new
selection is made. The accounts returned with `accountsChanged` and by
`eth_accounts` are both ordered by this property.
The `updatePermittedAccounts` function was merged with the internal
methods for responding to account selection, to keep things simpler. It
wasn't called externally anyway, so it wasn't needed in the public API.
* Remove caveat update upon change in selected account
The order of accounts in the caveat isn't meaningful, so the caveat
doesn't need to be updated when the accounts get re-ordered.
* Emit event regardless of account order
Now that we're no longer relying upon the caveat for the account order,
we also have no way of knowing if a particular account selection
resulted in a change in order or not. The notification is now emitted
whenever an exposed account is selected - even if the order stayed the
same.
The inpage provider currently caches the account order, so it can be
relied upon to ignore these redundant events. We were already emiting
redundant `accountsChanged` events in some cases anyway.
Selecting a new account now results in all domains that can view this
change being notified. Previously only the dapp in the active tab was
being notified (though not correctly, as the `origin` was accidentally
set to the MetaMask chrome extension origin).
