Currently, the network controller notifies consumers about events by
emitting them directly from the controller. In order to migrate the
controller to the core repo, where controllers use the BaseControllerV2
interface, events should be emitted via a messenger object.
This commit updates the network controller to use a messenger, and then
updates all of the controllers that listen for network events to use the
messenger as well.

The `HardwareKeyringTypes` constant has been renamed to `KeyringTypes`
and moved to a separate constants module, to reflect that it contains
more than just hardware wallet keyring types. This corrects a mistake
made recently during a TypeScript conversion.
When the network client tests in this repo were copied over to the core
repo, some alterations were made. This commit copies them back to this
repo so that the two test suites are easier to compare to each other.
Changes include:
* Extracting `testsFor*` functions (functions that bundle similar tests
together) into separate files
* Reordering the tests defined in
`testsForRpcMethodsThatCheckForBlockHashInResponse`
* Reordering the set of RPC methods listed in `shared-tests.js`
* Reordering the type definitions defined in `shared-tests.js` to be
closer to the functions that use them
* Updating the tests defined in `testsForRpcMethodSupportingBlockParam`
so that when they make requests they pass params, even if it's just an
empty array
* Revert "Moved subscribe and filter into network controller (#16693)"
This reverts commit 6f6984fa58. That
commit was an RPC middleware refactor intended to move the subscribe
and filter middleware into the network controller, to simplify the
process of sharing this middleware between clients.
This refactor resulted in `eth_subscribe` notifications being sent on
the wrong connections, causing the UI to break in some cases (the UI
`provider` connection does not support notifications). This happened
because the `setupProviderEngine` function runs per-connection,
whereas the engine setup inside the network controller is global. The
global network client cannot support notifications because it has no
way to route them; they'll need to stay in the per-connection provider
engine.
Closes#17467
* Add e2e test
An e2e test has been added that confirms subscriptions are only
broadcast to the site that registered them. This test fails on
`develop`.

* Use tokenList to get token details, when available, in getTokenStandardAndDetails
Previously, every call to getTokenStandardAndDetails would fetch data via the provider.
This would result in at least 3 network requests whenever that method is called for an
ERC20 token, contributing to unneccesary loading and lagging in multiple places.
This commit takes advantage of stored data we already have available to avoid the unnecessary
loading.

The migration template has been converted to TypeScript. We can start
writing migrations in TypeScript today; they have no dependencies on
JavaScript modules.
This release only includes one breaking change, which is the renaming
of the package to be under the `@metamask` scope. It includes
improvements to the types that will unblock migrating our network
clients to TypeScript.
The PhishingController has been updated to v2. This release should
dramatically reduce network traffic and double the update speed of the
phishing list.
This was accomplished by combining both of our phishing configurations
into one list (the "stalelist"), then creating a separate list of the
changes just the past few days (the "hotlist"). Now users will download
a smaller list more frequently (every 30 minutes rather than every
hour), whereas the full list is only updated every 4 days.
The combined configuration means that we no longer know which list was
responsible for each block. The phishing warning page has been updated
to dynamically look this information up, to ensure users are still
directed to the correct place to dispute a block. This update to the
phishing warning page also includes the recent redesign.

Now that we are adding the UI
there's no need for this rpc middleware
(as it was used to test desktop background
code)
* fix: display experimental tab for desktop
The network controller has a variety of methods that just retrieve
controller state. These methods are not necessary because controller
state is already part of the public API of the controller and can be
accessed directly.
These methods are:
- getCurrentChainId
- getCurrentRpcUrl
- getNetworkIdentifier
- getNetworkState
- getProviderConfig
- isNetworkLoading
This is part of a larger effort to normalize the API of both network
controllers, to make them easier to merge.
Use DesktopManager in background script to redirect internal and external connections to the desktop app.
Include DesktopController in the MetaMask controller.
Support desktop keyrings in MetaMask controller via the overrides object.
Create middleware handler to connect to the desktop app while UI code is pending.
Add build system support for desktop specific configuration variables.
The network controller has some tests, but they are incomplete and don't
follow our latest best practices for writing unit tests.
This commit greatly increases the amount of test coverage for the API
that we want to retain in NetworkController, in particular the seemingly
myriad paths that the code takes starting from `initializeProvider`,
`resetConnection`, `setRpcTarget`, `setProviderType`,
`rollbackToPreviousProvider`, and `lookupNetwork`.
There were a couple of pieces of logic I noted which don't seem to have
any effect due to being redundant or unreachable, but they also don't
make our lives more difficult, either, so I opted to leave them in.

* Add tests for `retryOnEmpty` middleware
Tests have been added for the `retryOnEmpty` middleware.
This middleware is only used on the Infura network client, so the tests
that demonstrate this retry behavior are only enabled for the `infura`
provider type.
Most of the tests added were to cover cases where the retry middleware
is skipped, so they were applicable for both provider types.
Closes#17004
* Improve readability of block number tests
The test cases for passing a block number parameter have been made more
readable. Specifically, a comment has been added each time params are
built to call attention to the block parameter and what value it has,
so that it's clear whether it's larger or smaller than the current
block number.
Additionally the blocks for "less than the current block number" and
"equal to the current block number" have been combined using
`describe.each`.
Tests have been added to ensure that our middleware will not return a
cached response to a request with unique parameters. Each parameter
supported by each method is tested independently.
Closes#17003

Support has been restored for Chromium v78. Previously the extension
would crash upon startup.
The main incompatibility was the use of ES2020 operators (the optional
chain and nullish coalesce operators) in the libraries
`@ethereumjs/util` and `superstruct`. This was resolved by transpiling
those libraries.
After fixing that, the extension no longer crashed but the UI refused
to connect. This was because the UI process was not being identified as
an internal process, because the code responsible for checking that was
relying on the `origin` property of `MessageSender` [1] which wasn't
added until Chromium v80. The check has been updated to use the `url`
property instead, which existed in older versions of Chrome.
Lastly, the content security policy was updated to include the default
content security policy alongside the intended modification. Newer
versions of Chrome will merge the configired CSP with the default, but
older versions required it to be explicitly specified. This should not
result in any functional change.

The network controller is now constructed within each network
controller unit test, rather than in the `beforeEach`. This allows us
to customize the constructor options in each test, which some planned
future tests will require.
The controller is constructed with a helper function that also handles
calling `destroy` after each test, even if the test failed. This helps
to prevent tests from affecting each other.

This test was testing a function that was only present in the test
module.
The function under test was mistakenly moved here when it was
discovered that it wasn't being used elsewhere, under the assumption
that it was used in these tests. I hadn't realized it was being tested
directly.
The network controller unit tests now use network mocks rather than
mocking controller methods.
This makes the tests less brittle, as they will no longer break when
internal changes to the `_getLatestBlock` method are made.
* Ensure that account tracker does not set balances incorrectly when useMultiAccountBalanceChecker is false
* Lint fix
* Fix account setting in _updateAccount in useMultiAccountBalanceChecker === true case
* Fix _updateAccount
* Add unit tests
The network controller unit tests have been updated to wait until the
network controller is fully initialized before proceeding. This ensures
that the initialization doesn't have any side-effects that affect later
tests.
The NetworkController `destroy` method has been updated to ensure that
it no longer throws if called before initialization.
This method was added recently in #17032, but we forgot to handle the
case where the controller was not initialized.
The `initializeProvider` parameters were removed recently in #16863,
but they were still being set in tests. They have now been removed.
An unused property was also being set in the tests, which has now also
been removed.
The "MetaMask middleware" is the set of middleware for handling methods that
we don't send to the network. This includes signing, encryption, `getAccounts`,
and methods that rely on pending transaction state.
Previously this middleware was setup as part of the network client, despite
having nothing to do with the network. They have been moved into the main RPC
pipeline established in `metamask-controller.js` instead.
This is a pure refactor, and should have no functional changes. The middleware
are still run in exactly the same order with the same arguments.
Previously we had written tests for `createInfuraClient`, which creates a middleware stack designed to connect to an Infura provider. These tests exercise various RPC methods that relate to the behavior that the middleware provides (mainly around caching).
Now we need to write the same tests but for `createJsonRpcClient`, which creates a middleware stack designed to connect to a non-Infura RPC endpoint. To do this, we had to:
- Consolidate the tests for both types of RPC client into a single test file.
- Add conditions around tests or assertions in tests to account for differences in behavior between the two sets of middleware stacks.
- Relocate code in `createJsonRpcClient` which slows down `eth_estimateGas` calls just for tests so that this behavior can be disabled in the network client tests.
Eventually, as we unify the network controllers in this repo and in the core repo, we will move these tests into the core repo.

Our middleware for handling subscription and filter-related methods (`eth-json-rpc-filters`) currently lives in our RPC pipeline ahead of the network stack. This commit moves this middleware to the network client middleware instead. There are two reasons for this change. First, this middleware wraps RPC methods that are supported by the network. Second, it is necessary for this middleware to live with the network client so that it will aid us in unifying the NetworkController in this repo and the NetworkController in the `controllers` repo.
Co-authored-by: Elliot Winkler <elliot.winkler@gmail.com>
The network controller module has been renamed from `network.js` to
`network-controller.js`. All of our newer controllers have "controller"
in the module names, so this aligns better with that convention. It
also brings the test module name into alignment (it's already called
"network-controller.test.js").
* Make `initializeProvider` and `lookupNetwork` async
These two methods were "synchronous" previously, but initiated an
asynchronous operation. They have both been made `async` to bring them
more in-line with the mobile controller API, and to make them easier
to test.
This should include zero functional changes. These methods are still
being invoked without an `await`, to preserve the same behaviour they
had previously.
This relates to https://github.com/MetaMask/controllers/issues/971
* Move 'net_version' query to private function
* Fix error made when resolving conflicts
* Refactor to improve readability
This commit affects the network client tests, which were added in a
previous PR to test the behavior of `createInfuraClient`, a function
called that sets up a portion of the middleware stack in the JSON-RPC
layer.
An `if` statement appears in the tests which limits the execution of
certain tests. However, this seems to have been added for debugging
purposes and is not actually needed.

Five network controller methods have been renamed to start with an
underscore:
* `getLatestBlock`
* `setNetworkState`
* `setNetworkEIPSupport`
* `clearNetworkDetails`
* `setProviderConfig`
All of these methods were used solely within the network controller.
The leading underscore now documents these methods as being private.
A few tests required updates as well because they were stubbing out one
of these methods.
This should include zero functional changes.
This relates to https://github.com/MetaMask/controllers/issues/971
The network state is now passed to the TransactionController via a
getter function and a subscription function, instead of passing one of
the network controller stores directly.
This way of passing the state makes further refactoring easier, as we
don't have to change the input when the store is changed or replaced.
It's also more aligned with our conventions today.
This change was made as part of a larger refactor of the network
controller, as part of the effort to merge the mobile and extension
network controllers.
The network controller method `setProviderType` was marked as `async`
despite doing nothing async internally. The `async` has been dropped.
This should have zero functional impact.
This relates to https://github.com/MetaMask/controllers/issues/971
The network controller `setInfuraProjectId` method has been deleted.
The Infura project ID is only ever set upon construction, so it is now
passed in as a constructor parameter instead.
Rather than adding this as a second parameter, the network controller
now uses an "options bag" for constructor parameters. The initial state
was the first parameter, but it's now passed in as the `state` option
instead.
These changes make the API more similar to the mobile network
controller API.
This should have zero functional changes.

* Simplify MV3 initialization
The MV3 initialization logic was complicated and introduced race
difficult-to-reproduce race conditions when dapps connect during
initialization.
It seems that problems were encountered after the UI tried to connect
before the background was initialized. To address this, the
initialization step was _delayed_ until after the first connection.
That first connection was then passed into the initialization function,
and setup properly after initialization had begun.
However, this special treatment is only given for the first connection.
Subsequent connections that still occur during initialization would
fail. This also results in the initialization being needlessly delayed,
which is concerning given that our main performance goal is to speed it
up.
