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.
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.
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.
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).
This handling of account selection has been moved into the background
to minimize the gap between account selection and the notification
being sent out. It's simpler for the UI to not be involved anyway.
Previously all browser globals were allowed to be used anywhere by
ESLint because we had set the `env` property to `browser` in the ESLint
config. This has made it easy to accidentally use browser globals
(e.g. #8338), so it has been removed. Instead we now have a short list
of allowed globals.
All browser globals are now accessed as properties on `window`.
Unfortunately this change resulted in a few different confusing unit
test errors, as some of our unit tests setup assumed that a particular
global would be used via `window` or `global`. In particular,
`window.fetch` didn't work correctly because it wasn't patched by the
AbortController polyfill (only `global.fetch` was being patched).
The `jsdom-global` package we were using complicated matters by setting
all of the JSDOM `window` properties directly on `global`, overwriting
the `AbortController` for example.
The `helpers.js` test setup module has been simplified somewhat by
removing `jsdom-global` and constructing the JSDOM instance manually.
The JSDOM window is set on `window`, and a few properties are set on
`global` as well as needed by various dependencies. `node-fetch` and
the AbortController polyfill/patch now work as expected as well,
though `fetch` is only available on `window` now.
The tests for the detect-tokens controller were nearly all broken. They
have been fixed, and a few improvements were made to controller itself
to help with this.
* The core `detectNewTokens` method has been updated to be async, so
that the caller can know when the operation had completed.
* The part of the function that used `Web3` to check the token balances
has been split into a separate function, so that that part could be
stubbed out in tests. Eventually we should test this using `ganache`
instead, but this was an easier first step.
* The internal `tokenAddresses` array is now initialized on
construction, rather than upon the first Preferences controller update.
The `detectNewTokens` function would have previously failed if it ran
prior to this initialization, so it was failing if called before any
preferences state changes.
Additionally, the `detectTokenBalance` function was removed, as it was
no longer used.
The tests have been updated to ensure they're actually testing the
behavior they purport to be testing. I've simulated a test failure with
each one to check that it'd fail when it should. The preferences
controller instance was updated to set addresses correctly as well.
