In the `core` version of NetworkController, `removeNetworkConfiguration`
throws an error if the given network configuration ID doesn't match an
existing network configuration. This commits adds the same check for
consistency. It also makes some minor changes to the implementation and
tests for `removeNetworkConfiguration` for consistency as well.
The network controller method `setActiveNetwork` is now async, and the
asynchronous `_setProviderConfig` step is now awaited. The function
will not resolve until the network has finished switching.
This change affects the `eth_switchEthereumChain` and
`eth_addEthereumChain` middleware, and it affects any network switching
performed in our UI.

The network controller method `setProviderType` is now async, and the
async operation `_setProviderConfig` called at the end of the method is
now awaited.
Because the only async operation was the last step, this should have no
impact upon the flow of execution. The only functional change is that
now any callers have the option of waiting until the network switch
operation has completed.
One such change was made, in the `switch-ethereum-chain` middleware. As
a result, an error thrown while the network is switching will now
be thrown in this middleware and returned to the dapp as an internal
error.

* Consolidate network stores
The network controller used to have multiple different state stores,
which were composed together to form the main controller state store.
They have been consolidated into a single store. This required few
changes because most state access was already being done through the
composed store.
Fixes https://github.com/MetaMask/metamask-extension/issues/18303
* Add JSDoc comment
Internal network controller methods and fields are now private fields,
using the JavaScript `#` syntax rather than the `private` TypeScript
keyword or a leading underscore.
The one reference to a private field was in the preferences controller
unit tests. Fortunately it was being used to create a test fixture that
was unused. The unnecessary test fixtures have been removed from that
test suite.
Fixes https://github.com/MetaMask/metamask-extension/issues/18588
The network controller internal method `_setProviderConfig` has been
made async, the async `_switchNetwork` operation is now `await`-ed.
Since the `_switchNetwork` call was the last operation, this has zero
functional impact.

* Remove the network controller `previousProviderStore`
The `previousProvider` network controller state has been replaced with
a private internal property. This was only used internally, it did not
need to be part of state.
This relates to https://github.com/MetaMask/metamask-extension/issues/18303
* Remove redundant tests
The network controller internal method `_switchNetwork` has been made
async, and the `lookupNetwork` call is now awaited. Because this method
is only used internally, and because the `await`-ed async operation was
the last operation in this function, this change has no functional
impact whatsoever.

In order to be able to better compare differences between the version of
NetworkController in this repo and the version in the `core` repo before
we replace this version with the `core` version, this commit converts
the NetworkController network client tests to TypeScript.
The added types here are copied from the `core` repo. We plan on
making more improvements on the `core` side at some point to polish the
tests and types and reduce some of the duplication, but for now we're
just trying to keep things as similar as possible.
This helps us more easily compare the unit tests for NetworkController
in this repo and the NetworkController in the `core` repo.

Converting this controller to TypeScript furthers the goal of getting
this whole codebase converted, of course, but it also helps in comparing
the differences between this version of the NetworkController and the
version in the `core` repo more easily, which will ultimately help us in
coalescing the two implementations.

* Update `@metamask/swappable-obj-proxy`
The package `@metamask/swappable-obj-proxy` has been updated to the
latest version. The breaking changes include moving the package under
the `@metamask` scope and converting it to TypeScript.
* Update policy
The package `safe-event-emitter` has been updated to v2. This update
includes renaming the package to be scoped under `@metamask`, and it
includes a TypeScript migration.
We want to convert NetworkController to TypeScript in order to be able
to compare differences in the controller between in this repo and the
core repo. To do this, however, we need to convert the dependencies of
the controller to TypeScript.
As a part of this effort, this commit converts
`shared/constants/metametrics` to TypeScript. Note that simple objects
have been largely replaced with enums. There are some cases where I even
split up some of these objects into multiple enums.

The `network` store of the network controller crams two types of data
into one place. It roughly tracks whether we have enough information to
make requests to the network and whether the network is capable of
receiving requests, but it also stores the ID of the network (as
obtained via `net_version`).
Generally we shouldn't be using the network ID for anything, as it has
been completely replaced by chain ID, which all custom RPC endpoints
have been required to support for over a year now. However, as the
network ID is used in various places within the extension codebase,
removing it entirely would be a non-trivial effort. So, minimally, this
commit splits `network` into two stores: `networkId` and
`networkStatus`. But it also expands the concept of network status.
Previously, the network was in one of two states: "loading" and
"not-loading". But now it can be in one of four states:
- `available`: The network is able to receive and respond to requests.
- `unavailable`: The network is not able to receive and respond to
requests for unknown reasons.
- `blocked`: The network is actively blocking requests based on the
user's geolocation. (This is specific to Infura.)
- `unknown`: We don't know whether the network can receive and respond
to requests, either because we haven't checked or we tried to check
and were unsuccessful.
This commit also changes how the network status is determined —
specifically, how many requests are used to determine that status, when
they occur, and whether they are awaited. Previously, the network
controller would make 2 to 3 requests during the course of running
`lookupNetwork`.
* First, if it was an Infura network, it would make a request for
`eth_blockNumber` to determine whether Infura was blocking requests or
not, then emit an appropriate event. This operation was not awaited.
* Then, regardless of the network, it would fetch the network ID via
`net_version`. This operation was awaited.
* Finally, regardless of the network, it would fetch the latest block
via `eth_getBlockByNumber`, then use the result to determine whether
the network supported EIP-1559. This operation was awaited.
Now:
* One fewer request is made, specifically `eth_blockNumber`, as we don't
need to make an extra request to determine whether Infura is blocking
requests; we can reuse `eth_getBlockByNumber`;
* All requests are awaited, which makes `lookupNetwork` run fully
in-band instead of partially out-of-band; and
* Both requests for `net_version` and `eth_getBlockByNumber` are
performed in parallel to make `lookupNetwork` run slightly faster.
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.
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`.
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 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.
