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.
* fix failed off chain tx mismatch with next confirmed transaction
* dont drop failed txs when tx in confirmed
* add comment for reassigning logic
* resolve change requests
When a lot of transactions are occurring on the network, such as during
an NFT drop, it drives gas fees up. When this happens, we want to not
only inform the user about this, but also dissuade them from using a
higher gas fee (as we have proved in testing that high gas fees can
cause bidding wars and exacerbate the situation).
The method for determining whether the network is "busy" is already
handled by GasFeeController, which exposes a `networkCongestion`
property within the gas fee estimate data. If this number exceeds 0.66 —
meaning that the current base fee is above the 66th percentile among the
base fees over the last several days — then we determine that the
network is "busy".
ESLint rules have been added to enforce our JSDoc conventions. These
rules were introduced by updating `@metamask/eslint-config` to v9.
Some of the rules have been disabled because the effort to fix all lint
errors was too high. It might be easiest to enable these rules one
directory at a time, or one rule at a time.
Most of the changes in this PR were a result of running
`yarn lint:fix`. There were a handful of manual changes that seemed
obvious and simple to make. Anything beyond that and the rule was left
disabled.
