From 19092ac8c354b92c2e0e27b73f391571ad452505 Mon Sep 17 00:00:00 2001 From: Andrew Clark Date: Tue, 3 Aug 2021 22:30:20 -0400 Subject: [PATCH] Re-add old Fabric Offscreen impl behind flag (#22018) * Re-add old Fabric Offscreen impl behind flag There's a chance that #21960 will affect layout in a way that we don't expect, so I'm adding back the old implementation so we can toggle the feature with a flag. The flag should read from the ReactNativeFeatureFlags shim so that we can change it at runtime. I'll do that separately. * Import dynamic RN flags from external module Internal feature flags that we wish to control with a GK can now be imported from an external module, which I've called "ReactNativeInternalFeatureFlags". We'll need to add this module to the downstream repo. We can't yet use this in our tests, because we don't have a test configuration that runs against the React Native feature flags fork. We should set up that up the same way we did for www. --- .../src/ReactFabricHostConfig.js | 26 ++++++ .../src/createReactNoop.js | 48 ++++++++++ .../src/ReactFiberBeginWork.new.js | 12 ++- .../src/ReactFiberBeginWork.old.js | 12 ++- .../src/ReactFiberCompleteWork.new.js | 87 ++++++++++++++++--- .../src/ReactFiberCompleteWork.old.js | 87 ++++++++++++++++--- .../ReactFiberHostConfigWithNoPersistence.js | 2 + .../src/ReactFiberThrow.new.js | 3 +- .../src/ReactFiberThrow.old.js | 3 +- .../src/forks/ReactFiberHostConfig.custom.js | 2 + packages/shared/ReactFeatureFlags.js | 2 + .../ReactFeatureFlags.native-fb-dynamic.js | 29 +++++++ .../forks/ReactFeatureFlags.native-fb.js | 8 ++ .../forks/ReactFeatureFlags.native-oss.js | 1 + .../forks/ReactFeatureFlags.test-renderer.js | 1 + .../ReactFeatureFlags.test-renderer.native.js | 1 + .../ReactFeatureFlags.test-renderer.www.js | 1 + .../shared/forks/ReactFeatureFlags.testing.js | 1 + .../forks/ReactFeatureFlags.testing.www.js | 1 + .../forks/ReactFeatureFlags.www-dynamic.js | 1 + .../shared/forks/ReactFeatureFlags.www.js | 2 + scripts/flow/config/flowconfig | 1 + scripts/flow/xplat.js | 12 +++ scripts/rollup/bundles.js | 23 +++-- scripts/rollup/modules.js | 2 + 25 files changed, 324 insertions(+), 44 deletions(-) create mode 100644 packages/shared/forks/ReactFeatureFlags.native-fb-dynamic.js create mode 100644 scripts/flow/xplat.js diff --git a/packages/react-native-renderer/src/ReactFabricHostConfig.js b/packages/react-native-renderer/src/ReactFabricHostConfig.js index db9e5039f5373..8ca9401597ddb 100644 --- a/packages/react-native-renderer/src/ReactFabricHostConfig.js +++ b/packages/react-native-renderer/src/ReactFabricHostConfig.js @@ -460,6 +460,32 @@ export function getOffscreenContainerProps( } } +export function cloneHiddenInstance( + instance: Instance, + type: string, + props: Props, + internalInstanceHandle: Object, +): Instance { + const viewConfig = instance.canonical.viewConfig; + const node = instance.node; + const updatePayload = create( + {style: {display: 'none'}}, + viewConfig.validAttributes, + ); + return { + node: cloneNodeWithNewProps(node, updatePayload), + canonical: instance.canonical, + }; +} + +export function cloneHiddenTextInstance( + instance: Instance, + text: string, + internalInstanceHandle: Object, +): TextInstance { + throw new Error('Not yet implemented.'); +} + export function createContainerChildSet(container: Container): ChildSet { return createChildNodeSet(container); } diff --git a/packages/react-noop-renderer/src/createReactNoop.js b/packages/react-noop-renderer/src/createReactNoop.js index bc31a1c7c3cae..9e2c1ba7f876c 100644 --- a/packages/react-noop-renderer/src/createReactNoop.js +++ b/packages/react-noop-renderer/src/createReactNoop.js @@ -582,6 +582,54 @@ function createReactNoop(reconciler: Function, useMutation: boolean) { children, }; }, + + cloneHiddenInstance( + instance: Instance, + type: string, + props: Props, + internalInstanceHandle: Object, + ): Instance { + const clone = cloneInstance( + instance, + null, + type, + props, + props, + internalInstanceHandle, + true, + null, + ); + clone.hidden = true; + return clone; + }, + + cloneHiddenTextInstance( + instance: TextInstance, + text: string, + internalInstanceHandle: Object, + ): TextInstance { + const clone = { + text: instance.text, + id: instance.id, + parent: instance.parent, + hidden: true, + context: instance.context, + }; + // Hide from unit tests + Object.defineProperty(clone, 'id', { + value: clone.id, + enumerable: false, + }); + Object.defineProperty(clone, 'parent', { + value: clone.parent, + enumerable: false, + }); + Object.defineProperty(clone, 'context', { + value: clone.context, + enumerable: false, + }); + return clone; + }, }; const NoopRenderer = reconciler(hostConfig); diff --git a/packages/react-reconciler/src/ReactFiberBeginWork.new.js b/packages/react-reconciler/src/ReactFiberBeginWork.new.js index a687e9d16315d..9c5ca07008552 100644 --- a/packages/react-reconciler/src/ReactFiberBeginWork.new.js +++ b/packages/react-reconciler/src/ReactFiberBeginWork.new.js @@ -89,6 +89,7 @@ import { enableLazyContextPropagation, enableSuspenseLayoutEffectSemantics, enableSchedulingProfiler, + enablePersistentOffscreenHostContainer, } from 'shared/ReactFeatureFlags'; import invariant from 'shared/invariant'; import isArray from 'shared/isArray'; @@ -146,7 +147,6 @@ import { registerSuspenseInstanceRetry, supportsHydration, isPrimaryRenderer, - supportsMutation, supportsPersistence, getOffscreenContainerProps, } from './ReactFiberHostConfig'; @@ -744,7 +744,7 @@ function updateOffscreenComponent( workInProgress.updateQueue = spawnedCachePool; } - if (supportsPersistence) { + if (enablePersistentOffscreenHostContainer && supportsPersistence) { // In persistent mode, the offscreen children are wrapped in a host node. // TODO: Optimize this to use the OffscreenComponent fiber instead of // an extra HostComponent fiber.
