Summary: In #32695, the `Performance.now()` implementation changed to use unix epoch timestamps instead of a monotonic clock. This is problematic, because it means that performance measurements get skewed if the device clock changes between two measurements. With this change, the clock is now monotonic (and the implementation stays consistent between platforms). More details and repro steps can be found in [this issue](#33977) Closes #33977 ## Changelog [General] [Fixed] - Use monotonic clock for performance.now() Pull Request resolved: #33983 Test Plan: Run on iOS and Android: ``` const now = global.performance.now() console.log(`${Platform.OS}: ${now}`) ``` Reviewed By: JoshuaGross, cipolleschi Differential Revision: D37066999 Pulled By: dmitryrykun fbshipit-source-id: 298547bf39faea1b025c17ff2d2e1a03f929865b

* Update script from prepublish (deprecated) to prepack (facebook#34198) Summary: Currently `react-native-codegen` uses `prepublish` to pre-build before publishing. Moving to `prepare` as `prepublish` is deprecated and not invoked anymore: https://docs.npmjs.com/cli/v8/using-npm/scripts#life-cycle-scripts ## Changelog [Internal][Fixed] - [codegen] Update script from prepublish (deprecated) to prepack Pull Request resolved: facebook#34198 Test Plan: Tested locally with: ``` cd packages/react-native-codegen/ && rm -rf lib && npm publish --dry-run --foreground-scripts ``` output is: ``` > react-native-codegen@0.70.1 prepare > yarn run build yarn run v1.22.18 $ yarn clean && node scripts/build.js --verbose $ rm -rf lib

ReactRootView has an id other than -1 instead of crashing the app in hybrid apps. (facebook#33133) Summary: As per commit: facebook@4f3b174 which states that "React Native requires that the RootView id be managed entirely by React Native, and will crash in addRootView/startSurface if the native View id isn't set to NO_ID." This behaviour can not be guaranteed in **hybrid** apps that have a native android layer over which ReactRootViews are added and the native views need to have ids on them in order to work. **The control of views can jump back and forth between native android and react-native (fabric). As the ReactRootView is added to ViewGroups (or layouts) in Android Fragments and Activities, they contain ids on their views which might get passed down to the reactRootView by features like DataBinding** Hence this can cause unnecessary crashes at runtime for hybrid apps even when they are not changing the id of the reactRootView object they are adding to their ViewGroups. Our app is a hybrid app that uses both native android and react-native on different screens and on one such screen that has a Fragment adding a ReactRootView to its FrameLayout to render native android views to render in ReactNative, this crash occurs on pressing the back button as well as on unlocking the screen while staying on the same screen. The app was running fine on more than a 100 million devices on React Native 0.63.4 but after updating to 0.67.2, that features this commit, it crashes on the very first device it was tested on. Refer to the issue: facebook#33121 for more information on the crash The fragment in which this issues arises is like this: ```binding.frameLayout.addView(getReactRootView())``` where getReactRootView() is like this: ``` private var mReactRootView: ReactRootView? = null private var mReactInstanceManager: ReactInstanceManager? = null mReactRootView = ReactRootView(context) if (activity != null) { val application = activity?.application if (application is MainApplication) { mReactInstanceManager = application.reactInstanceManager } } fun getReactRootView():View?{ return mReactRootView } ``` So converting this to a soft exception such that pure react-native devs can still see the error while hybrid apps continue to run without crashes. ### Snippet of the change: ``` if (getId() != View.NO_ID) { ReactSoftExceptionLogger.logSoftException( TAG, new IllegalViewOperationException( "Trying to attach a ReactRootView with an explicit id already set to [" + getId() + "]. React Native uses the id field to track react tags and will overwrite this" + " field. If that is fine, explicitly overwrite the id field to View.NO_ID.")); } ``` ## Changelog [GENERAL] [ADDED] - A ReactSoftException log instead of a direct exception being thrown: ``` if (getId() != View.NO_ID) { ReactSoftExceptionLogger.logSoftException( TAG, new IllegalViewOperationException( "Trying to attach a ReactRootView with an explicit id already set to [" + getId() + "]. React Native uses the id field to track react tags and will overwrite this" + " field. If that is fine, explicitly overwrite the id field to View.NO_ID.")); } ``` [GENERAL] [REMOVED]- Directly throwing an exception even when the code is not responsible for this issue: ``` if (getId() != View.NO_ID) { throw new IllegalViewOperationException( "Trying to attach a ReactRootView with an explicit id already set to [" + getId() + "]. React Native uses the id field to track react tags and will overwrite this" + " field. If that is fine, explicitly overwrite the id field to View.NO_ID."); } ``` Pull Request resolved: facebook#33133 Test Plan: This crash is hard to reproduce but when it occurs, this is the only way to fix it. If any app used to crash with this exact error, it will no longer crash but show an error log in Logcat for developers to be informed about the issue.

This is problematic, because it means that performance measurements get skewed if the device clock changes between two measurements. With this change, the clock is now monotonic (and the implementation stays consistent between platforms).

(facebook#33952) Summary: The current implementation of **getDefaultJSExecutorFactory** relies solely on try catch to load the correct .so file for jsc or hermes based on the project configuration. Relying solely on try catch block and loading jsc even when project is using hermes can lead to launch time crashes especially in monorepo architectures and hybrid apps using both native android and react native. So we can make use of an additional **ReactInstanceManager :: setJsEngineAsHermes** method that accepts a Boolean argument from the host app while building ReactInstanceManager which can tell which library to load at startup in **ReactInstanceManagerBuilder** which will now have an enhanced getDefaultJSExecutorFactory method that will combine the old logic with the new one to load the dso files. The code snippet in **ReactInstanceManager** for adding a new setter method: ``` /** * Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call * Uses the enum {link JSInterpreter} * param jsEngine */ private void setJSEngine(JSInterpreter jsEngine){ this.jsEngine = jsEngine; } /** * Utility setter to set the required JSEngine as HERMES or JSC * Defaults to OLD_LOGIC if not called by the host app * param hermesEnabled * hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise */ public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){ if(hermesEnabled){ setJSEngine(JSInterpreter.HERMES); } else{ setJSEngine(JSInterpreter.JSC); } return this; } ``` The code snippet for the new logic in **ReactInstanceManagerBuilder**: 1) Setting up the new logic: Adding a new enum class : ``` public enum JSInterpreter { OLD_LOGIC, JSC, HERMES } ``` A setter getting boolean value telling whether to use hermes or not and calling a private setter to update the enum variable. ``` /** * Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call * Uses the enum {link JSInterpreter} * param jsEngine */ private void setJSEngine(JSInterpreter jsEngine){ this.jsEngine = jsEngine; } /** * Utility setter to set the required JSEngine as HERMES or JSC * Defaults to OLD_LOGIC if not called by the host app * param hermesEnabled * hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise */ public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){ if(hermesEnabled){ setJSEngine(JSInterpreter.HERMES); } else{ setJSEngine(JSInterpreter.JSC); } return this; } ``` 2) Modifying the getDefaultJSExecutorFactory method to incorporate the new logic with the old one: ``` private JavaScriptExecutorFactory getDefaultJSExecutorFactory( String appName, String deviceName, Context applicationContext) { // Relying solely on try catch block and loading jsc even when // project is using hermes can lead to launch-time crashes especially in // monorepo architectures and hybrid apps using both native android // and react native. // So we can use the value of enableHermes received by the constructor // to decide which library to load at launch // if nothing is specified, use old loading method // else load the required engine if (jsEngine == JSInterpreter.OLD_LOGIC) { try { // If JSC is included, use it as normal initializeSoLoaderIfNecessary(applicationContext); JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } catch (UnsatisfiedLinkError jscE) { if (jscE.getMessage().contains("__cxa_bad_typeid")) { throw jscE; } HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } } else if (jsEngine == JSInterpreter.HERMES) { HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } else { JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } } ``` ### **Suggested changes in any Android App's MainApplication that extends ReactApplication to take advantage of this fix** ``` builder = ReactInstanceManager.builder() .setApplication(this) .setJsEngineAsHermes(BuildConfig.HERMES_ENABLED) .setBundleAssetName("index.android.bundle") .setJSMainModulePath("index") ``` where HERMES_ENABLED is a buildConfigField based on the enableHermes flag in build.gradle: `def enableHermes = project.ext.react.get("enableHermes", true) ` and then ``` defaultConfig{ if(enableHermes) { buildConfigField("boolean", "HERMES_ENABLED", "true") } else{ buildConfigField("boolean", "HERMES_ENABLED", "false") } } ``` Our app was facing a similar issue as listed in this list: **https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO**. Which was react-native trying to load jsc even when our project used hermes when a debug build was deployed on a device using android studio play button. This change can possibly solve many of the issues listed in the list as it solved ours. ## Changelog [GENERAL] [ADDED] - An enum JSInterpreter in com.facebook.react package: ``` /** * An enum that specifies the JS Engine to be used in the app * Old Logic uses the legacy code * JSC/HERMES loads the respective engine using the revamped logic */ public enum JSInterpreter { OLD_LOGIC, JSC, HERMES } ``` [GENERAL] [ADDED] - An enum variable storing the default value of Js Engine loading mechanism in ReactInstanceManagerBuilder: ``` private JSInterpreter jsEngine = JSInterpreter.OLD_LOGIC; ``` [GENERAL] [ADDED] - A new setter method and a helper method to set the js engine in ReactInstanceManagerBuilder: ``` /** * Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call * Uses the enum {link JSInterpreter} * param jsEngine */ private void setJSEngine(JSInterpreter jsEngine){ this.jsEngine = jsEngine; } /** * Utility setter to set the required JSEngine as HERMES or JSC * Defaults to OLD_LOGIC if not called by the host app * param hermesEnabled * hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise */ public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){ if(hermesEnabled){ setJSEngine(JSInterpreter.HERMES); } else{ setJSEngine(JSInterpreter.JSC); } return this; } ``` [GENERAL] [ADDED] - Modified **getDefaultJSExecutorFactory** method ``` private JavaScriptExecutorFactory getDefaultJSExecutorFactory( String appName, String deviceName, Context applicationContext) { // Relying solely on try catch block and loading jsc even when // project is using hermes can lead to launch-time crashes especially in // monorepo architectures and hybrid apps using both native android // and react native. // So we can use the value of enableHermes received by the constructor // to decide which library to load at launch // if nothing is specified, use old loading method // else load the required engine if (jsEngine == JSInterpreter.OLD_LOGIC) { try { // If JSC is included, use it as normal initializeSoLoaderIfNecessary(applicationContext); JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } catch (UnsatisfiedLinkError jscE) { if (jscE.getMessage().contains("__cxa_bad_typeid")) { throw jscE; } HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } } else if (jsEngine == JSInterpreter.HERMES) { HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } else { JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } } ``` Pull Request resolved: facebook#33952 Test Plan: The testing for this change might be tricky but can be done by following the reproduction steps in the issues related to DSO loading here: https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO Generally, the app will not crash anymore on deploying debug using android studio if we are removing libjsc and its related libraries in **packagingOptions** in build.gradle and using hermes in the project.

ReactRootView has an id other than -1 instead of crashing the app in hybrid apps. (facebook#33133) Summary: As per commit: facebook@4f3b174 which states that "React Native requires that the RootView id be managed entirely by React Native, and will crash in addRootView/startSurface if the native View id isn't set to NO_ID." This behaviour can not be guaranteed in **hybrid** apps that have a native android layer over which ReactRootViews are added and the native views need to have ids on them in order to work. **The control of views can jump back and forth between native android and react-native (fabric). As the ReactRootView is added to ViewGroups (or layouts) in Android Fragments and Activities, they contain ids on their views which might get passed down to the reactRootView by features like DataBinding** Hence this can cause unnecessary crashes at runtime for hybrid apps even when they are not changing the id of the reactRootView object they are adding to their ViewGroups. Our app is a hybrid app that uses both native android and react-native on different screens and on one such screen that has a Fragment adding a ReactRootView to its FrameLayout to render native android views to render in ReactNative, this crash occurs on pressing the back button as well as on unlocking the screen while staying on the same screen. The app was running fine on more than a 100 million devices on React Native 0.63.4 but after updating to 0.67.2, that features this commit, it crashes on the very first device it was tested on. Refer to the issue: facebook#33121 for more information on the crash The fragment in which this issues arises is like this: ```binding.frameLayout.addView(getReactRootView())``` where getReactRootView() is like this: ``` private var mReactRootView: ReactRootView? = null private var mReactInstanceManager: ReactInstanceManager? = null mReactRootView = ReactRootView(context) if (activity != null) { val application = activity?.application if (application is MainApplication) { mReactInstanceManager = application.reactInstanceManager } } fun getReactRootView():View?{ return mReactRootView } ``` So converting this to a soft exception such that pure react-native devs can still see the error while hybrid apps continue to run without crashes. ### Snippet of the change: ``` if (getId() != View.NO_ID) { ReactSoftExceptionLogger.logSoftException( TAG, new IllegalViewOperationException( "Trying to attach a ReactRootView with an explicit id already set to [" + getId() + "]. React Native uses the id field to track react tags and will overwrite this" + " field. If that is fine, explicitly overwrite the id field to View.NO_ID.")); } ``` ## Changelog [GENERAL] [ADDED] - A ReactSoftException log instead of a direct exception being thrown: ``` if (getId() != View.NO_ID) { ReactSoftExceptionLogger.logSoftException( TAG, new IllegalViewOperationException( "Trying to attach a ReactRootView with an explicit id already set to [" + getId() + "]. React Native uses the id field to track react tags and will overwrite this" + " field. If that is fine, explicitly overwrite the id field to View.NO_ID.")); } ``` [GENERAL] [REMOVED]- Directly throwing an exception even when the code is not responsible for this issue: ``` if (getId() != View.NO_ID) { throw new IllegalViewOperationException( "Trying to attach a ReactRootView with an explicit id already set to [" + getId() + "].

If that is fine, explicitly overwrite the id field to View.NO_ID."); } ``` Pull Request resolved: facebook#33133 Test Plan: This crash is hard to reproduce but when it occurs, this is the only way to fix it. If any app used to crash with this exact error, it will no longer crash but show an error log in Logcat for developers to be informed about the issue.

(facebook#33952) Summary: The current implementation of **getDefaultJSExecutorFactory** relies solely on try catch to load the correct .so file for jsc or hermes based on the project configuration. Relying solely on try catch block and loading jsc even when project is using hermes can lead to launch time crashes especially in monorepo architectures and hybrid apps using both native android and react native. So we can make use of an additional **ReactInstanceManager :: setJsEngineAsHermes** method that accepts a Boolean argument from the host app while building ReactInstanceManager which can tell which library to load at startup in **ReactInstanceManagerBuilder** which will now have an enhanced getDefaultJSExecutorFactory method that will combine the old logic with the new one to load the dso files. The code snippet in **ReactInstanceManager** for adding a new setter method: ``` /** * Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call * Uses the enum {link JSInterpreter} * param jsEngine */ private void setJSEngine(JSInterpreter jsEngine){ this.jsEngine = jsEngine; } /** * Utility setter to set the required JSEngine as HERMES or JSC * Defaults to OLD_LOGIC if not called by the host app * param hermesEnabled * hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise */ public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){ if(hermesEnabled){ setJSEngine(JSInterpreter.HERMES); } else{ setJSEngine(JSInterpreter.JSC); } return this; } ``` The code snippet for the new logic in **ReactInstanceManagerBuilder**: 1) Setting up the new logic: Adding a new enum class : ``` public enum JSInterpreter { OLD_LOGIC, JSC, HERMES } ``` A setter getting boolean value telling whether to use hermes or not and calling a private setter to update the enum variable. ``` /** * Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call * Uses the enum {link JSInterpreter} * param jsEngine */ private void setJSEngine(JSInterpreter jsEngine){ this.jsEngine = jsEngine; } /** * Utility setter to set the required JSEngine as HERMES or JSC * Defaults to OLD_LOGIC if not called by the host app * param hermesEnabled * hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise */ public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){ if(hermesEnabled){ setJSEngine(JSInterpreter.HERMES); } else{ setJSEngine(JSInterpreter.JSC); } return this; } ``` 2) Modifying the getDefaultJSExecutorFactory method to incorporate the new logic with the old one: ``` private JavaScriptExecutorFactory getDefaultJSExecutorFactory( String appName, String deviceName, Context applicationContext) { // Relying solely on try catch block and loading jsc even when // project is using hermes can lead to launch-time crashes especially in // monorepo architectures and hybrid apps using both native android // and react native. // So we can use the value of enableHermes received by the constructor // to decide which library to load at launch // if nothing is specified, use old loading method // else load the required engine if (jsEngine == JSInterpreter.OLD_LOGIC) { try { // If JSC is included, use it as normal initializeSoLoaderIfNecessary(applicationContext); JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } catch (UnsatisfiedLinkError jscE) { if (jscE.getMessage().contains("__cxa_bad_typeid")) { throw jscE; } HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } } else if (jsEngine == JSInterpreter.HERMES) { HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } else { JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } } ``` ### **Suggested changes in any Android App's MainApplication that extends ReactApplication to take advantage of this fix** ``` builder = ReactInstanceManager.builder() .setApplication(this) .setJsEngineAsHermes(BuildConfig.HERMES_ENABLED) .setBundleAssetName("index.android.bundle") .setJSMainModulePath("index") ``` where HERMES_ENABLED is a buildConfigField based on the enableHermes flag in build.gradle: `def enableHermes = project.ext.react.get("enableHermes", true) ` and then ``` defaultConfig{ if(enableHermes) { buildConfigField("boolean", "HERMES_ENABLED", "true") } else{ buildConfigField("boolean", "HERMES_ENABLED", "false") } } ``` Our app was facing a similar issue as listed in this list: **https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO**. Which was react-native trying to load jsc even when our project used hermes when a debug build was deployed on a device using android studio play button. This change can possibly solve many of the issues listed in the list as it solved ours. ## Changelog [GENERAL] [ADDED] - An enum JSInterpreter in com.facebook.react package: ``` /** * An enum that specifies the JS Engine to be used in the app * Old Logic uses the legacy code * JSC/HERMES loads the respective engine using the revamped logic */ public enum JSInterpreter { OLD_LOGIC, JSC, HERMES } ``` [GENERAL] [ADDED] - An enum variable storing the default value of Js Engine loading mechanism in ReactInstanceManagerBuilder: ``` private JSInterpreter jsEngine = JSInterpreter.OLD_LOGIC; ``` [GENERAL] [ADDED] - A new setter method and a helper method to set the js engine in ReactInstanceManagerBuilder: ``` /** * Sets the jsEngine as JSC or HERMES as per the setJsEngineAsHermes call * Uses the enum {link JSInterpreter} * param jsEngine */ private void setJSEngine(JSInterpreter jsEngine){ this.jsEngine = jsEngine; } /** * Utility setter to set the required JSEngine as HERMES or JSC * Defaults to OLD_LOGIC if not called by the host app * param hermesEnabled * hermesEnabled = true sets the JS Engine as HERMES and JSC otherwise */ public ReactInstanceManagerBuilder setJsEngineAsHermes(boolean hermesEnabled){ if(hermesEnabled){ setJSEngine(JSInterpreter.HERMES); } else{ setJSEngine(JSInterpreter.JSC); } return this; } ``` [GENERAL] [ADDED] - Modified **getDefaultJSExecutorFactory** method ``` private JavaScriptExecutorFactory getDefaultJSExecutorFactory( String appName, String deviceName, Context applicationContext) { // Relying solely on try catch block and loading jsc even when // project is using hermes can lead to launch-time crashes especially in // monorepo architectures and hybrid apps using both native android // and react native. // So we can use the value of enableHermes received by the constructor // to decide which library to load at launch // if nothing is specified, use old loading method // else load the required engine if (jsEngine == JSInterpreter.OLD_LOGIC) { try { // If JSC is included, use it as normal initializeSoLoaderIfNecessary(applicationContext); JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } catch (UnsatisfiedLinkError jscE) { if (jscE.getMessage().contains("__cxa_bad_typeid")) { throw jscE; } HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } } else if (jsEngine == JSInterpreter.HERMES) { HermesExecutor.loadLibrary(); return new HermesExecutorFactory(); } else { JSCExecutor.loadLibrary(); return new JSCExecutorFactory(appName, deviceName); } } ``` Pull Request resolved: facebook#33952 Test Plan: The testing for this change might be tricky but can be done by following the reproduction steps in the issues related to DSO loading here: https://github.com/facebook/react-native/issues?q=is%3Aissue+is%3Aopen+DSO Generally, the app will not crash anymore on deploying debug using android studio if we are removing libjsc and its related libraries in **packagingOptions** in build.gradle and using hermes in the project.

Description
In React Native 0.68, the
Performance.now()implementation changed to use unix epoch timestamps instead of a monotonic clock in #32695 (both on iOS and Android).This is problematic, because it means that performance measurements get skewed if the device clock changes between two measurements.

Steps to reproduce
Use this repo to easily output and diff
performance.now()timestamps (or create a sample app with a button that outputs theperformance.now()timestamp to the console):The difference between the two timestamps will be >24h.
That is not the case when doing the same repro steps on RN 0.67.4 (since the clock is monotonic).
Snack, code example, screenshot, or link to a repository
Use this repo to easily output and diff
