* bump package to latest
* update files to respect lint
* disable object-type-delimiter rule to work with prettier
* disable rule to let flow check pass
This is done so that any effects scheduled by the shallow render are thrown away.
Unlike the code this was forked from (in ReactComponentStackFrame) DevTools should override the dispatcher even when DevTools is compiled in production mode, because the app itself may be in development mode and log errors/warnings.
DevTools shared Babel config previously supported IE 11 to target Hermes (for the standalone backend that gets embedded within React Native apps). This targeting resulted in less optimal code for other DevTools targets though which did not need to support IE 11. This PR updates the shared config to remove IE 11 support by default, and only enables it for the standalone backend target.
* Improve DevTools editing interface
This commit adds the ability to rename or delete keys in the props/state/hooks/context editor and adds tests to cover this functionality. DevTools will degrade gracefully for older versions of React that do not inject the new reconciler rename* or delete* methods.
Specifically, this commit includes the following changes:
* Adds unit tests (for modern and legacy renderers) to cover overriding props, renaming keys, and deleting keys.
* Refactor backend override methods to reduce redundant Bridge/Agent listeners and methods.
* Inject new (DEV-only) methods from reconciler into DevTools to rename and delete paths.
* Refactor 'inspected element' UI components to improve readability.
* Improve auto-size input to better mimic Chrome's Style editor panel. (See this Code Sandbox for a proof of concept.)
It also contains the following code cleanup:
* Additional unit tests have been added for modifying values as well as renaming or deleting paths.
* Four new DEV-only methods have been added to the reconciler to be injected into the DevTools hook: overrideHookStateDeletePath, overrideHookStateRenamePath, overridePropsDeletePath, and overridePropsRenamePath. (DevTools will degrade gracefully for older renderers without these methods.)
* I also took this as an opportunity to refactor some of the existing code in a few places:
* Rather than the backend implementing separate methods for editing props, state, hooks, and context– there are now three methods: deletePath, renamePath, and overrideValueAtPath that accept a type argument to differentiate between props, state, context, or hooks.
* The various UI components for the DevTools frontend have been refactored to remove some unnecessary repetition.
This commit also adds temporary support for override* commands with mismatched backend/frontend versions:
* Add message forwarding for older backend methods (overrideContext, overrideHookState, overrideProps, and overrideState) to the new overrideValueAtPath method. This was done in both the frontend Bridge (for newer frontends passing messages to older embedded backends) and in the backend Agent (for older frontends passing messages to newer backends). We do this because React Native embeds the React DevTools backend, but cannot control which version of the frontend users use.
* Additional unit tests have been added as well to cover the older frontend to newer backend case. Our DevTools test infra does not make it easy to write tests for the other way around.
In the next major release, we intend to drop support for using the `act`
testing helper in production. (It already fires a warning.) The
rationale is that, in order for `act` to work, you must either mock the
testing environment or add extra logic at runtime. Mocking the testing
environment isn't ideal because it requires extra set up for the user.
Extra logic at runtime is fine only in development mode — we don't want
to slow down the production builds.
Since most people only run their tests in development mode, dropping
support for production should be fine; if there's demand, we can add it
back later using a special testing build that is identical to the
production build except for the additional testing logic.
One blocker for removing production support is that we currently use
`act` to test React itself. We must test React in both development and
production modes.
So, the solution is to fork `act` into separate public and
internal implementations:
- *public implementation of `act`* – exposed to users, only works in
development mode, uses special runtime logic, does not support partial
rendering
- *internal implementation of `act`* – private, works in both
development and productionm modes, only used by the React Core test
suite, uses no special runtime logic, supports partial rendering (i.e.
`toFlushAndYieldThrough`)
The internal implementation should mostly match the public
implementation's behavior, but since it's a private API, it doesn't have
to match exactly. It works by mocking the test environment: it uses a
mock build of Scheduler to flush rendering tasks, and Jest's mock timers
to flush Suspense placeholders.
---
In this first commit, I've added the internal forks of `act` and
migrated our tests to use them. The public `act` implementation is
unaffected for now; I will leave refactoring/clean-up for a later step.

DevTools has a feature to force a Suspense boundary to show a fallback.
This feature causes us to skip the first render pass (where we render
the primary children) and go straight to rendering the fallback.
There's a Legacy Mode-only codepath that failed to take this scenario
into account, instead assuming that whenever a fallback is being
rendered, it was preceded by an attempt to render the primary children.
SuspenseList can also cause us to skip the first pass, but the relevant
branch is Legacy Mode-only, and SuspenseList is not supported in
Legacy Mode.
Fixes a test that I had temporarily disabled when upstreaming the Lanes
implementation in #19108.
* Add autofix to cross-fork lint rule
* replace-fork: Replaces old fork contents with new
For each file in the new fork, copies the contents into the
corresponding file of the old fork, replacing what was already there.
In contrast to merge-fork, which performs a three-way merge.
* Replace old fork contents with new fork
First I ran `yarn replace-fork`.
Then I ran `yarn lint` with autofix enabled. There's currently no way to
do that from the command line (we should fix that), so I had to edit the
lint script file.
* Manual fix-ups
Removes dead branches, removes prefixes from internal fields. Stuff
like that.
* Fix DevTools tests
DevTools tests only run against the old fork, which is why I didn't
catch these earlier.
There is one test that is still failing. I'm fairly certain it's related
to the layout of the Suspense fiber: we no longer conditionally wrap the
primary children. They are always wrapped in an extra fiber.
Since this has been running in www for weeks without major issues, I'll
defer fixing the remaining test to a follow up.
