Rick Hanlon 98b03fa1b9 Switch native codegen over to flow parser
Summary:
This diff switches the native codegen over to the flow parser

It does this by:
- Creating a new e2e directory
- Migrating the schema.js fixtures to flow types in  e2e/
- Updating the buck tests to use the flow type fixtures
- Finally, updating the rest of rn_codegen to use *NativeComponent instead of *Schema.js

Removing all of the schemas in the next diff to keep this one clean

Dan Abramov ea817fd7f5 Don't symbolicate transform errors
Summary:
Metro symbolication can be expensive in large apps. However, there is no need to symbolicate _runtime stacks from compile errors_. Those are pretty much useless anyway.

This will reduce the workload on Metro workers, and the delays when iterating with Fast Refresh, as the server will be busy much less often.

So I'm special-casing them and not sending the symbolication request anymore.

Pavlos Vinieratos dff35882a3 add passwordRules for textContentType newPassword (#25407)
Summary:
On `textContentType` `newPassword` on ios, there is another property called `passwordRules` on ios 12 that can give hints to the os to generate a password with specific requirements like [here](https://developer.apple.com/password-rules/).
This is useful for apps that have a "register" screen with `emailAddress`/`username` and a `newPassword` fields, to let ios make a password that will satisfy the requirements and not one that might be not accepted after the user presses "register".

## Changelog

[iOS] [Added] - PasswordRules for new password textContentType input fields
Pull Request resolved: https://github.com/facebook/react-native/pull/25407

Test Plan: This is a bit harder, but to test you need to make an app that has associated domains with an apple-app-site-association file on that domain, enable iCloud Keychain on the test device, and then iOS will suggest a password, otherwise you will just get a warning on Xcode saying "Couldn't suggest password because of: blabla".

`setUseLineSpacingFromFallbacks` is recommended to set true on [document](https://developer.android.com/reference/android/text/StaticLayout.Builder#setUseLineSpacingFromFallbacks(boolean))

>For backward compatibility reasons, the default is false, but setting this to true is strongly recommended. It is required to be true if text could be in languages like Burmese or Tibetan where text is typically much taller or deeper than Latin text.

Summary: `ReactPackageTurboModuleManagerDelegate.getLegacyCxxModule` isn't called from Java. Therefore, ProGuard will strip this method to reduce code size. To prevent this, we need to add the `DoNotStrip` annotation to this method. This annotation isn't necessary for the `getModule` method, since `getModule` is used in `TurboModuleManager.getJavaModule`.

Eli White 0a34fb78ab RN iOS: Support View Manager Commands that are strings
Summary:
Right now JS triggers a view manager command with the following code:

```
UIManager.dispatchViewManagerCommand(
  nullthrows(this.scrollResponderGetScrollableNode()),
  UIManager.getViewManagerConfig('RCTScrollView').Commands.scrollTo,
  [x || 0, y || 0, animated !== false],
);
```

As we want to get rid of calls to UIManager, we need to stop looking for the integer defined in native from JavaScript. We will be changing methods like this to be:

```
UIManager.dispatchViewManagerCommand(
  nullthrows(this.scrollResponderGetScrollableNode()),
  'scrollTo',
  [x || 0, y || 0, animated !== false],
);
```

We need to support ints and Strings to be backwards compatible, but ints will be deprecated.

This is the same change as made for Android here: https://github.com/facebook/react-native/commit/3cae6fa950eed54bccccf61a28c0e85d5a004c6c

Rubén Norte f9ecce7440 Create RootTagContext and provide it in AppContainer
Summary:
We should remove all usages of React's legacy context API because it'll be removed from React at some point, it prevents some performance optimizations in updates and can cause conflicts between different context providers (like mixins).

This creates a new Context for `rootTag` (this granularity is intentional) so users that are consuming it via the legacy context API can start migrating away from it.

I didn't create a more generic context (like ReactRootContext, ReactApplicationContext) because having a more granular context makes it easier to track and remove it if we want to, and prevents re-rendering when users only care about certain values.

Eli White 3cae6fa950 RN Android: Support View Manager Commands that are strings
Summary:
Right now JS triggers a view manager command with the following code:

```
UIManager.dispatchViewManagerCommand(
  ReactNative.findNodeHandle(this),
  UIManager.getViewManagerConfig('RCTView').Commands.hotspotUpdate,
  [destX || 0, destY || 0],
);
```

As we want to get rid of calls to UIManager, we need to stop looking for the integer defined in native from JavaScript. We will be changing methods like this to be:

```
UIManager.dispatchViewManagerCommand(
  ReactNative.findNodeHandle(this),
  'hotspotUpdate',
  [destX || 0, destY || 0],
);
```

We need to support ints and Strings to be backwards compatible, but ints will be deprecated.

Dan Abramov 0a17699fd5 Recover from render errors by remounting root
Summary: This updates the renderer and Fresh packages to pull in the new error handling behavior. The new feature is that roots that errored on last save get remounted after an edit. This allows much faster iteration in the Fast Refresh mode as you don't need to do a full reload after typos.

Dan Abramov cf7813a625 Downgrade "packager disconnected" to a warning
Summary:
If the error doesn't come in direct response to a user action, I think a redbox is too severe. I think we don't want to associate turning on Fast Refresh with a higher frequency of redboxes. So this downgrades these messages to warnings.

If you manually try to turn it off and on again, we'll still show a redbox to remind why it's not working.

Dan Abramov a52e6d1dbb Unify "Hot Reloading" and "Reload-on-Save" into "Fast Refresh"
Summary:
We have too many options in the Dev Menu, and they're really hard to pick from. They're also somewhat conflicting. This replaces two menu choices that have a similar purpose (faster iteration cycle) with one.

"Fast Refresh" tries to only update the affected modules, but falls back to doing a full reload if the update can't be handled by the React components.

If for some reason you prefer the "Reload-on-Save" behavior, please:

- Reach out to me so I can learn more about your use case.
- As a workaround, you can add `if (__DEV__) require.Refresh.forceFullRefresh = true` to your app's entry point to always do a full refresh.

Also note that I only removed the user-facing part of "Reload-on-Save". So if you have automation depending on it, that's gonna keep working.

I moved it above Systrace since it's a more generic feature.

As a total aside nit, I renamed "Enable Inspector" and "Disable Inspector" to "Show Inspector" and "Hide Inspector" because... that's what those options do, really.

Dan Abramov 08bfdfad67 Remove useless module.hot checks
Summary:
Since we always create `module.hot` objects, the `module.hot` checks were unnecessary. They give a false impression that we're checking for a Hot Reloading mode. However, they're just Flow refinements and always exist in DEV. I made that explicit by throwing early.

Similarly, I removed a `module.hot` check inside `setupReactRefresh`, as it is always truish in DEV.

Finally, I'm adding a new mechanism as an escape hatch. It lets you do:

```
if (__DEV__) {
  require.Refresh.forceFullRefresh = true;
}
```

in your entry point and opt into full refreshes on every edit. This sounds similar to "Reload-on-Save". That is because in the next diff, I plan to remove "Reload-on-Save" from user-visible options (but it'll stay for automated workflows).

So this workaround is intended for people who for one reason or another don't want to opt into Hot Reloading as an alternative. We'll need to talk to them and find out why.

Dan Abramov 1f04ff580d Make "Enable Hot Reloading" Instant
Summary:
As we saw in D15947985, and later traced down to D5623623, the `hot` option isn't used by Metro anymore. The relevant transforms _always_ run in DEV regardless of the option.

Given that, it doesn't make sense that enabling or disabling Hot Reloading forces a full refresh. This significantly raises the usage barrier because **currently, you might have to wait ~20 seconds (on a large app) to just start using Hot Reloading when you're already in the middle of some screen.** So you just end up not using it.

This diff changes enabling/disabling Hot Reloading to be _instant_.

Here's how it works:

1. Now we always send the necessary info to the client via the new `HMRClient.setup()` function. It creates a Metro HMR client instance, but only actually sets up the socket if Hot Reloading is on.

2. The "Enable Hot Reloading" menu no longer forces a reload. Instead, it calls `HMRClient.enable()` which lazily sets up a socket (at most once).

3. The "Disable Hot Reloading" menu also doesn't trigger a refresh now. Instead, it calls `HMRClient.disable()`. We don't actually tear down the socket here because it's a pain to deal with race conditions and such. Instead, we keep the connection — but we _ignore the updates_ that come in while we're disabled.

4. As a result, it is possible to enable and disable it many times during a single session. (Updates while disabled would be ignored — which has a risk of making your running app inconsistent — but I'd argue it's expected and is worth it. You can always save a particular file to force it to update once the mode is on.)

5. In order to support "ignoring" updates, Metro's `HMRClient` (not to be confused with RN's module) now supports a `shouldApplyUpdates` field. The RN module uses it to disable handling updates when the mode is off.

6. In case there is an error that makes hot reloading unavailable (such as the server disconnecting), we surface the error only if the mode is on. If the mode is off, we stash the error message in the `_hmrUnavailableReason` variable, and display it next time you try to enable Hot Reloading.
