The state snapshot that was attached to Sentry errors was removed
recently in #8794 because it had become too large. The snapshot has
now been restored and reduced in size.
A utility function has been written to reduce the state object to just
the requested properties. This seemed safer than filtering out state
that is known to be large or to contain identifiable information.
This is not a great solution, as now knowledge about the state shape
resides in this large constant, but it will suffice for now. I am
hopeful that we can decorate our controllers with this metadata in the
future instead, as part of the upcoming background controller refactor.
A separate `getSentryState` global function has been added to get the
reduced state, so that the old `getCleanAppState` function that we used
to use could remain unchanged. It's still useful to get that full state
copy while debugging, and in e2e tests.
The state snapshot we were attaching to Sentry errors was too large.
As a temporary solution, it has been removed completely. We can re-add
it later after reducing its size.
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.
Errors without stack traces would break the Sentry error processing,
which assumes the presence of a stack trace. Many errors don't have any
stack trace though, such as uncaught promises.
This breakage resulting in the app state being missing from the error
report, and a console warning.
Any error sent to Sentry will now be marked with the environment they
were sent from. The environment is set at build time, and is set
dependant upon the build flags and CI-related environment variables.
Setting the environment will let us filter error reports in Sentry to
focus specifically upon reports sent from production, release
candidates, PR testing, or whatever else.
Previously, all errors encountered during testing or production were
sent to the primary `metamask` Sentry project, whereas development
errors were sent to `test-metamask` instead. This change ensures that
errors encountered during tests are sent to `test-metamask` as well.
