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.
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.
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.
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.
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.
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.
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.
