Environment variables are now considered as higher-precedence than
configuration by our build system. This means that if the same value is
set in `.metamaskrc` and in an environment variable, the environment
variable is what will be used. Previously the reverse was true, the
configuration would take precedence.
It is conventional for CLI tools to consider environment variables as
higher precedence than configuration. This makes our build system less
surprising for most people.
We are working on migrating the extension to a unified network
controller, but before we do so we want to extract some of the existing
pieces, specifically `createInfuraClient` and `createJsonRpcClient`,
which provide the majority of the behavior exhibited within the provider
API that the existing NetworkController exposes. This necessitates that
we understand and test that behavior as a whole.
With that in mind, this commit starts with the Infura-specific network
client and adds some initial functional tests for `createInfuraClient`,
specifically covering three pieces of middleware provided by
`eth-json-rpc-middleware`: `createNetworkAndChainIdMiddleware`,
`createBlockCacheMiddleware`, and `createBlockRefMiddleware`.
These tests exercise logic that originate from multiple different places
and combine in sometimes surprising ways, and as a result, understanding
the nature of the tests can be tricky. I've tried to explain the logic
(both of the implementation and the tests) via comments. Additionally,
debugging why a certain test is failing is not the most fun thing in the
world, so to aid with this, I've added some logging to the underlying
packages used when a request passes through the middleware stack.
Because some middleware change the request being made, or make new
requests altogether, this greatly helps to peel back the curtain, as
failures from Nock do not supply much meaningful information on their
own. This logging is disabled by default, but can be activated by
setting `DEBUG=metamask:*,eth-query DEBUG_COLORS=1` alongside the `jest`
command.
We use this logging by bumping `eth-block-tracker`, and
`eth-json-rpc-middleware`.
* Update `eth-json-rpc-infura`
The package `eth-json-rpc-infura@5` has been updated to
`@metamask/eth-json-rpc-infura@7`. This update includes TypeScript
support, and it drops support for older node.js versions. The exports
have also been changed from default to named exports.
See here for a full list of changes: https://github.com/MetaMask/eth-json-rpc-infura/blob/main/CHANGELOG.md#700
* Fix LavaMoat policy issue
The `web3` package used by `@metamask/controllers` unintentionally
overwrites the `XMLHttpRequest` global, which breaks things. This was
fixed by revoking `web3`'s write access to that global using a policy
override.
Previously this policy override was applied to `web3`, but for some
unknown reason, this update caused that override to no longer apply.
* using the aggregators from tokenList instead of detectedToken to avoid conflicts between static and dynamic list
* removing aggregator from the detectTokens object List
A patch made in #15672 was found to be unnecessary. Instead of setting
a `rootGlobals` object upon construction of the root compartment, we
are now creating a `sentryHooks` object in the initial top-level
compartment. I hadn't realized at the time that the root compartment
would inherit all properties of the initial compartment `globalThis`.
This accomplishes the same goals as #15672 except without needing a
patch.
The Sentry `Dedupe` integration has been filtering out our events, even
when they were never sent due to our `beforeSend` handler. It was
wrongly identifying them as duplicates because it has no knowledge of
`beforeSend` or whether they were actually sent or not.
To resolve this, the filtering we were doing in `beforeSend` has been
moved to a Sentry integration. This integration is installed ahead of
the `Dedupe` integration, so `Dedupe` should never find out about any
events that we filter out, and thus will never consider them as sent
when they were not.
Our Sentry setup relies upon application state, but it wasn't able to
access it in LavaMoat builds because it's running in a separate
Compartment.
A patch has been introduced to the LavaMoat runtime to allow the root
Compartment to mutate the `rootGlobals` object, which is accessible
from outside the compartment as well. This lets us expose application
state to our Sentry integration.
