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 `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).
We inject `web3` globally on most websites. This has been breaking
websites that attempted to serialize the `window` object, because any
attempt to access certain `web3` properties (such as `web3.eth.mining`)
would throw an error. This is because `web3` defined a getter for these
properties that would call `.send([method])`, which doesn't work for
most methods.
An example of a site that this breaks is `Storybook`, when the
`@storybook/addon-actions` addon is being used. When using storybook
with this addon and with the MetaMask extension installed, actions
would not be properly dispatched because an error would be thrown in
the attempt to serialize the event (which includes a reference to the
`window`).
The `web3` global we inject is now defined as non-enumerable, so it
will be skipped automatically in any attempt to serialize the `window`
object.
Defaults have been added for all three preferences. The default values
added are both falsey, so this shouldn't result in any functional
change. This was done to help make this preferences more easily
discoverable.
The max listener count of the preferences store has been increased to
12. Recently the 12th listener was added, which resulted in console
warnings during the unit tests - this prevents those warnings.
The default max listener value is 10; we didn't see this warning until
now because one of the twelve listeners is only setup when 3Box is
enabled, which doesn't occur during our unit tests.
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.
All transaction status updates were moved into a `setTimeout` callback
and wrapped in a `try...catch` block in #4131, apparently in an attempt
to prevent failures in event subscribers from interrupting the
transaction logic. The `try...catch` block did accomplish that, but by
putting the status update in a `setTimeout` callback the operation was
made asynchronous.
Transaction status updates now happen unpredictably, in some future
event loop from when they're triggered. This creates a race condition,
where the transaction status update may occur before or after
subsequent state changes. This also introduces a risk of accidentally
undoing a change to the transaction state, as the update made to the
transaction inside the `setTimeout` callback uses a reference to
`txMeta` obtained synchronously before the `setTimeout` call. Any
replacement of the `txMeta` between the `setTxStatus` call and the
execution of the timeout would be erased. Luckily the `txMeta` object
is more often than not mutated rather than replaced, which may explain
why we haven't seen this happen yet.
Everything seems to work correctly with the `setTimeout` call removed,
and now the transaction logic is easier to understand.
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.
The inactive timer was being reset upon any change to the preferences
store. The intent was only to update the timer when the auto-lock
timeout had changed, so the subscription was updated to only update in
those cases.
There are no indications that this had any effect upon the user. It
looks like the preferences store never updates while the extension is
unattended, so in practice this may have been harmless. It was still
pointless however. This also protects against the possibility of the
preferences store being updated while unattended at some point in the
future.
