- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-### Using Firebase from a Framework or a library
-
-[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md)
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/e3496d9/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/7963c3d/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](Example/Auth/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-### Using Firebase from a Framework or a library
-
-[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md)
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a

-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-### Using Firebase from a Framework or a library
-
-[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md)
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

-# Firebase iOS Open Source Development [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains a subset of the Firebase iOS SDK source. It currently
-includes FirebaseCore, FirebaseABTesting, FirebaseAuth, FirebaseDatabase,
-FirebaseFirestore, FirebaseFunctions, FirebaseInstanceID, FirebaseInAppMessaging,
-FirebaseInAppMessagingDisplay, FirebaseMessaging, FirebaseRemoteConfig, and
-FirebaseStorage.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/e3496d9/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/7963c3d/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](Example/Auth/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, and Catalyst
-Thanks to contributions from the community, FirebaseABTesting, FirebaseAuth, FirebaseCore,
-FirebaseDatabase, FirebaseMessaging, FirebaseFirestore,
-FirebaseFunctions, FirebaseRemoteConfig, and FirebaseStorage now compile, run unit tests, and work on
-tvOS, macOS, and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-
-Keep in mind that macOS, Catalyst and tvOS are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS or tvOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting'
-pod 'Firebase/Auth'
-pod 'Firebase/Database'
-pod 'Firebase/Firestore'
-pod 'Firebase/Functions'
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig'
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

-/**
- * SyncTree is the central class for managing event callback registration, data

- * two SyncTree instances for each Repo, one for the normal Firebase data, and
- * one for the .info data.
- *
- * It has a number of responsibilities, including:
- * - Tracking all user event callbacks (registered via addEventRegistration:
- * and removeEventRegistration:).
- * - Applying and caching data changes for user setValue:,
- * runTransactionBlock:, and updateChildValues: calls
- * (applyUserOverwriteAtPath:, applyUserMergeAtPath:).
- * - Applying and caching data changes for server data changes
- * (applyServerOverwriteAtPath:, applyServerMergeAtPath:).
- * - Generating user-facing events for server and user changes (all of the
- * apply* methods return the set of events that need to be raised as a result).
- * - Maintaining the appropriate set of server listens to ensure we are always
- * subscribed to the correct set of paths and queries to satisfy the current set
- * of user event callbacks (listens are started/stopped using the provided
- * listenProvider).
- *
- * NOTE: Although SyncTree tracks event callbacks and calculates events to
- * raise, the actual events are returned to the caller rather than raised
- * synchronously.

- * up deallocating this class and the FConnection class before the websocket has
- * a change to call some of its delegate methods. So, since close is the
- * external close handler, we just set a flag saying not to call our own
- * delegate method and close the websocket. That will trigger a callback into

-/**
- * @fileoverview Implementation of an immutable SortedMap using a Left-leaning
- * Red-Black Tree, adapted from the implementation in Mugs
- * (http://mads379.github.com/mugs/) by Mads Hartmann Jensen
- * (mads379@gmail.com).
- *
- * Original paper on Left-leaning Red-Black Trees:
- * http://www.cs.princeton.edu/~rs/talks/LLRB/LLRB.pdf
- *
- * Invariant 1: No red node has a red child
- * Invariant 2: Every leaf path has the same number of black nodes
- * Invariant 3: Only the left child can be red (left leaning)

-/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
- The following encoding technique is taken from RFC 1521 by Borenstein
- and Freed. It is reproduced here in a slightly edited form for
- convenience.
-
- A 65-character subset of US-ASCII is used, enabling 6 bits to be
- represented per printable character. (The extra 65th character, "=",
- is used to signify a special processing function.)
-
- The encoding process represents 24-bit groups of input bits as output
- strings of 4 encoded characters. Proceeding from left to right, a
- 24-bit input group is formed by concatenating 3 8-bit input groups.
- These 24 bits are then treated as 4 concatenated 6-bit groups, each
- of which is translated into a single digit in the base64 alphabet.
-
- Each 6-bit group is used as an index into an array of 64 printable
- characters. The character referenced by the index is placed in the
- output string.
-
- Table 1: The Base64 Alphabet
-
- Value Encoding Value Encoding Value Encoding Value Encoding
- 0 A 17 R 34 i 51 z
- 1 B 18 S 35 j 52 0
- 2 C 19 T 36 k 53 1
- 3 D 20 U 37 l 54 2
- 4 E 21 V 38 m 55 3
- 5 F 22 W 39 n 56 4
- 6 G 23 X 40 o 57 5
- 7 H 24 Y 41 p 58 6
- 8 I 25 Z 42 q 59 7
- 9 J 26 a 43 r 60 8
- 10 K 27 b 44 s 61 9
- 11 L 28 c 45 t 62 +
- 12 M 29 d 46 u 63 /
- 13 N 30 e 47 v
- 14 O 31 f 48 w (pad) =
- 15 P 32 g 49 x
- 16 Q 33 h 50 y
-
- Special processing is performed if fewer than 24 bits are available
- at the end of the data being encoded. A full encoding quantum is
- always completed at the end of a quantity. When fewer than 24 input
- bits are available in an input group, zero bits are added (on the
- right) to form an integral number of 6-bit groups. Padding at the
- end of the data is performed using the '=' character.
-
- Since all base64 input is an integral number of octets, only the
- -------------------------------------------------
- following cases can arise:
-
- (1) the final quantum of encoding input is an integral
- multiple of 24 bits; here, the final unit of encoded
- output will be an integral multiple of 4 characters
- with no "=" padding,
- (2) the final quantum of encoding input is exactly 8 bits;
- here, the final unit of encoded output will be two
- characters followed by two "=" padding characters, or
- (3) the final quantum of encoding input is exactly 16 bits;
- here, the final unit of encoded output will be three
- characters followed by one "=" padding character.

-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```

-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

-// Using a monotonic clock is necessary because CFAbsoluteTimeGetCurrent(), NSDate, and related all
-// are subject to drift. That it to say, multiple consecutive calls do not always result in a

-// factors. This class attempts to determine the wall-clock time at the time of the event by
-// capturing the kernel start and time since boot to determine a wallclock time in UTC.
-//
-// Timezone offsets at the time of a snapshot are also captured in order to provide local-time

- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-### Using Firebase from a Framework or a library
-
-[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md)
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome
-
-Instructions for installing binary frameworks via
-[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
-
-### Using Firebase from a Framework or a library
-
-[Using Firebase from a Framework or a library](docs/firebase_in_libraries.md)
-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).
-
-## Roadmap
-
-See [Roadmap](ROADMAP.md) for more about the Firebase iOS SDK Open Source
-plans and directions.

-/// Comment from <a href="http://iphonedevwiki.net/index.php/Crack_prevention">iPhone Dev Wiki
-/// Crack Prevention</a>:
-/// App Store binaries are signed by both their developer and Apple. This encrypts the binary so
-/// that decryption keys are needed in order to make the binary readable. When iOS executes the
-/// binary, the decryption keys are used to decrypt the binary into a readable state where it is
-/// then loaded into memory and executed. iOS can tell the encryption status of a binary via the
-/// cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is a non-zero
-/// value then the binary is encrypted.
-///
-/// 'Cracking' works by letting the kernel decrypt the binary then siphoning the decrypted data into
-/// a new binary file, resigning, and repackaging. This will only work on jailbroken devices as
-/// codesignature validation has been removed. Resigning takes place because while the codesignature
-/// doesn't have to be valid thanks to the jailbreak, it does have to be in place unless you have
-/// AppSync or similar to disable codesignature checks.
-///
-/// More information at <a href="http://landonf.org/2009/02/index.html">Landon Fuller's blog</a>

-Comment from
-<a href="http://iphonedevwiki.net/index.php/Crack_prevention">iPhone Dev Wiki
-Crack Prevention</a>: App Store binaries are signed by both their developer
-and Apple. This encrypts the binary so that decryption keys are needed in order
-to make the binary readable. When iOS executes the binary, the decryption keys
-are used to decrypt the binary into a readable state where it is then loaded
-into memory and executed. iOS can tell the encryption status of a binary via the
-cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is
-a non-zero value then the binary is encrypted.
-
-'Cracking' works by letting the kernel decrypt the binary then siphoning the
-decrypted data into a new binary file, resigning, and repackaging. This will
-only work on jailbroken devices as codesignature validation has been removed.
-Resigning takes place because while the codesignature doesn't have to be valid
-thanks to the jailbreak, it does have to be in place unless you have AppSync or
-similar to disable codesignature checks.

- [](https://travis-ci.org/firebase/firebase-ios-sdk)
-
-This repository contains all Firebase iOS SDK source except FirebaseAnalytics,
-FirebasePerformance, and FirebaseML.
-
-The repository also includes GoogleUtilities source. The
-[GoogleUtilities](GoogleUtilities/README.md) pod is
-a set of utilities used by Firebase and other Google products.
-
-Firebase is an app development platform with tools to help you build, grow and
-monetize your app. More information about Firebase can be found at
-[https://firebase.google.com](https://firebase.google.com).
-
-## Installation
-
-See the three subsections for details about three different installation methods.
-1. [Standard pod install](README.md#standard-pod-install)
-1. [Installing from the GitHub repo](README.md#installing-from-github)
-1. [Experimental Carthage](README.md#carthage-ios-only)
-
-### Standard pod install
-
-Go to
-[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
-
-### Installing from GitHub
-
-For releases starting with 5.0.0, the source for each release is also deployed
-to CocoaPods master and available via standard
-[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
-
-These instructions can be used to access the Firebase repo at other branches,
-tags, or commits.
-
-#### Background
-
-See
-[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
-for instructions and options about overriding pod source locations.
-
-#### Accessing Firebase Source Snapshots
-
-All of the official releases are tagged in this repo and available via CocoaPods. To access a local
-source snapshot or unreleased branch, use Podfile directives like the following:
-
-To access FirebaseFirestore via a branch:
-```
-pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
-```
-
-To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
-
-```
-pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
-pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
-```
-
-### Carthage (iOS only)
-
-Instructions for the experimental Carthage distribution are at
-[Carthage](Carthage.md).
-
-### Rome

-
-## Development
-
-To develop Firebase software in this repository, ensure that you have at least
-the following software:
-
- * Xcode 10.1 (or later)
- * CocoaPods 1.7.2 (or later)
- * [CocoaPods generate](https://github.com/square/cocoapods-generate)
-
-For the pod that you want to develop:
-
-`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-
-Note: If the CocoaPods cache is out of date, you may need to run
-`pod repo update` before the `pod gen` command.
-
-Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
-those platforms. Since 10.2, Xcode does not properly handle multi-platform
-CocoaPods workspaces.
-
-Firestore has a self contained Xcode project. See
-[Firestore/README.md](Firestore/README.md).
-
-### Development for Catalyst
-* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
-* Check the Mac box in the App-iOS Build Settings
-* Sign the App in the Settings Signing & Capabilities tab
-* Click Pods in the Project Manager
-* Add Signing to the iOS host app and unit test targets
-* Select the Unit-unit scheme
-* Run it to build and test
-
-### Adding a New Firebase Pod
-
-See [AddNewPod.md](AddNewPod.md).
-
-### Code Formatting
-
-To ensure that the code is formatted consistently, run the script
-[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
-before creating a PR.
-
-Travis will verify that any code changes are done in a style compliant way. Install
-`clang-format` and `swiftformat`.
-These commands will get the right versions:
-
-```
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c6f1cbd/Formula/clang-format.rb
-brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/c13eda8/Formula/swiftformat.rb
-```
-
-Note: if you already have a newer version of these installed you may need to
-`brew switch` to this version.
-
-To update this section, find the versions of clang-format and swiftformat.rb to
-match the versions in the CI failure logs
-[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
-
-### Running Unit Tests
-
-Select a scheme and press Command-u to build a component and run its unit tests.
-
-#### Viewing Code Coverage (Deprecated)
-
-First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
-
-After running the `AllUnitTests_iOS` scheme in Xcode, execute
-`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
-at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
-
-### Running Sample Apps
-In order to run the sample apps and integration tests, you'll need valid
-`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
-files without real values, but can be replaced with real plist files. To get your own
-`GoogleService-Info.plist` files:
-
-1. Go to the [Firebase Console](https://console.firebase.google.com/)
-2. Create a new Firebase project, if you don't already have one
-3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
-identifier (e.g. `com.google.Database-Example`)
-4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
-(e.g. in [Example/Database/App/](Example/Database/App/));
-
-Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
-special Apple capabilities, and you will have to change the sample app to use a unique bundle
-identifier that you can control in your own Apple Developer account.
-
-## Specific Component Instructions
-See the sections below for any special instructions for those components.
-
-### Firebase Auth
-
-If you're doing specific Firebase Auth development, see
-[the Auth Sample README](FirebaseAuth/Tests/Sample/README.md) for instructions about
-building and running the FirebaseAuth pod along with various samples and tests.
-
-### Firebase Database
-
-To run the Database Integration tests, make your database authentication rules
-[public](https://firebase.google.com/docs/database/security/quickstart).
-
-### Firebase Storage
-
-To run the Storage Integration tests, follow the instructions in
-[FIRStorageIntegrationTests.m](FirebaseStorage/Tests/Integration/FIRStorageIntegrationTests.m).
-
-#### Push Notifications
-
-Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
-In order to actually test receiving push notifications, you will need to:
-
-1. Change the bundle identifier of the sample app to something you own in your Apple Developer
-account, and enable that App ID for push notifications.
-2. You'll also need to
-[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
-at **Project Settings > Cloud Messaging > [Your Firebase App]**.
-3. Ensure your iOS device is added to your Apple Developer portal as a test device.
-
-#### iOS Simulator
-
-The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
-In order to receive push notifications, you'll have to follow the steps above and run the app on a
-physical device.
-
-## Community Supported Efforts
-
-We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
-very grateful! We'd like to empower as many developers as we can to be able to use Firebase and
-participate in the Firebase community.
-
-### tvOS, macOS, watchOS and Catalyst
-Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
-tvOS, macOS, watchOS and Catalyst.
-
-For tvOS, checkout the [Sample](Example/tvOSSample).
-For watchOS, currently only Messaging and Storage (and their dependencies) have limited support. Checkout the
-[Independent Watch App Sample](Example/watchOSSample).
-
-Keep in mind that macOS, tvOS, watchOS and Catalyst are not officially supported by Firebase, and this
-repository is actively developed primarily for iOS. While we can catch basic unit test issues with
-Travis, there may be some changes where the SDK no longer works as expected on macOS, tvOS or watchOS. If you
-encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
-
-During app setup in the console, you may get to a step that mentions something like "Checking if the app
-has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/watchOS/Catalyst.
-**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
-
-To install, add a subset of the following to the Podfile:
-
-```
-pod 'Firebase/ABTesting' # No watchOS support yet
-pod 'Firebase/Auth' # No watchOS support yet
-pod 'Firebase/Crashlytics' # No watchOS support yet
-pod 'Firebase/Database' # No watchOS support yet
-pod 'Firebase/Firestore' # No watchOS support yet
-pod 'Firebase/Functions' # No watchOS support yet
-pod 'Firebase/Messaging'
-pod 'Firebase/RemoteConfig' # No watchOS support yet
-pod 'Firebase/Storage'
-```
-
-#### Additional Catalyst Notes
-
-* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
-to Build Settings.
-* FirebaseFirestore requires signing the
-[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

-Comment from
-<a href="http://iphonedevwiki.net/index.php/Crack_prevention">iPhone Dev Wiki
-Crack Prevention</a>: App Store binaries are signed by both their developer
-and Apple. This encrypts the binary so that decryption keys are needed in order
-to make the binary readable. When iOS executes the binary, the decryption keys
-are used to decrypt the binary into a readable state where it is then loaded
-into memory and executed. iOS can tell the encryption status of a binary via the
-cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is
-a non-zero value then the binary is encrypted.
-
-'Cracking' works by letting the kernel decrypt the binary then siphoning the
-decrypted data into a new binary file, resigning, and repackaging. This will
-only work on jailbroken devices as codesignature validation has been removed.
-Resigning takes place because while the codesignature doesn't have to be valid
-thanks to the jailbreak, it does have to be in place unless you have AppSync or
-similar to disable codesignature checks.

-Comment from
-<a href="http://iphonedevwiki.net/index.php/Crack_prevention">iPhone Dev Wiki
-Crack Prevention</a>: App Store binaries are signed by both their developer
-and Apple. This encrypts the binary so that decryption keys are needed in order
-to make the binary readable. When iOS executes the binary, the decryption keys
-are used to decrypt the binary into a readable state where it is then loaded
-into memory and executed. iOS can tell the encryption status of a binary via the
-cryptid structure member of LC_ENCRYPTION_INFO MachO load command. If cryptid is
-a non-zero value then the binary is encrypted.
-
-'Cracking' works by letting the kernel decrypt the binary then siphoning the
-decrypted data into a new binary file, resigning, and repackaging. This will
-only work on jailbroken devices as codesignature validation has been removed.
-Resigning takes place because while the codesignature doesn't have to be valid
-thanks to the jailbreak, it does have to be in place unless you have AppSync or
-similar to disable codesignature checks.

-**LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.**
-
-[](https://travis-ci.org/google/leveldb)
-[](https://ci.appveyor.com/project/pwnall/leveldb)
-
-Authors: Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
-
-# Features
-
- * Keys and values are arbitrary byte arrays.
- * Data is stored sorted by key.
- * Callers can provide a custom comparison function to override the sort order.
- * The basic operations are `Put(key,value)`, `Get(key)`, `Delete(key)`.
- * Multiple changes can be made in one atomic batch.
- * Users can create a transient snapshot to get a consistent view of data.
- * Forward and backward iteration is supported over the data.
- * Data is automatically compressed using the [Snappy compression library](http://google.github.io/snappy/).
- * External activity (file system operations etc.) is relayed through a virtual interface so users can customize the operating system interactions.

- [LevelDB library documentation](https://github.com/google/leveldb/blob/master/doc/index.md) is online and bundled with the source code.
-
-# Limitations
-
- * This is not a SQL database. It does not have a relational data model, it does not support SQL queries, and it has no support for indexes.
- * Only a single process (possibly multi-threaded) can access a particular database at a time.
- * There is no client-server support builtin to the library. An application that needs such support will have to wrap their own server around the library.
-
-# Building
-
-This project supports [CMake](https://cmake.org/) out of the box.
-
-### Build for POSIX
-
-Quick start:
-
-```bash
-mkdir -p build && cd build
-cmake -DCMAKE_BUILD_TYPE=Release .. && cmake --build .
-```
-
-### Building for Windows
-
-First generate the Visual Studio 2017 project/solution files:
-
-```cmd
-mkdir build
-cd build
-cmake -G "Visual Studio 15" ..
-```
-The default default will build for x86. For 64-bit run:
-
-```cmd
-cmake -G "Visual Studio 15 Win64" ..
-```
-
-To compile the Windows solution from the command-line:
-
-```cmd
-devenv /build Debug leveldb.sln
-```
-
-or open leveldb.sln in Visual Studio and build from within.
-
-Please see the CMake documentation and `CMakeLists.txt` for more advanced usage.
-
-# Contributing to the leveldb Project
-
-The leveldb project welcomes contributions. leveldb's primary goal is to be
-a reliable and fast key/value store. Changes that are in line with the
-features/limitations outlined above, and meet the requirements below,
-will be considered.
-
-Contribution requirements:
-
-1. **Tested platforms only**. We _generally_ will only accept changes for
- platforms that are compiled and tested. This means POSIX (for Linux and
- macOS) or Windows. Very small changes will sometimes be accepted, but
- consider that more of an exception than the rule.
-
-2. **Stable API**. We strive very hard to maintain a stable API. Changes that
- require changes for projects using leveldb _might_ be rejected without
- sufficient benefit to the project.
-
-3. **Tests**: All changes must be accompanied by a new (or changed) test, or
- a sufficient explanation as to why a new (or changed) test is not required.
-
-4. **Consistent Style**: This project conforms to the
- [Google C++ Style Guide](https://google.github.io/styleguide/cppguide.html).
- To ensure your changes are properly formatted please run:
-
- ```
- clang-format -i --style=file <file>
- ```
-
-## Submitting a Pull Request
-
-Before any pull request will be accepted the author must first sign a
-Contributor License Agreement (CLA) at https://cla.developers.google.com/.
-
-In order to keep the commit timeline linear
-[squash](https://git-scm.com/book/en/v2/Git-Tools-Rewriting-History#Squashing-Commits)
-your changes down to a single commit and [rebase](https://git-scm.com/docs/git-rebase)
-on google/leveldb/master. This keeps the commit timeline linear and more easily sync'ed
-with the internal repository at Google. More information at GitHub's
-[About Git rebase](https://help.github.com/articles/about-git-rebase/) page.

-# Performance
-
-Here is a performance report (with explanations) from the run of the
-included db_bench program. The results are somewhat noisy, but should
-be enough to get a ballpark performance estimate.
-
-## Setup
-
-We use a database with a million entries. Each entry has a 16 byte
-key, and a 100 byte value. Values used by the benchmark compress to
-about half their original size.
-
- LevelDB: version 1.1
- Date: Sun May 1 12:11:26 2011
- CPU: 4 x Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz
- CPUCache: 4096 KB
- Keys: 16 bytes each
- Values: 100 bytes each (50 bytes after compression)
- Entries: 1000000
- Raw Size: 110.6 MB (estimated)
- File Size: 62.9 MB (estimated)
-
-## Write performance
-
-The "fill" benchmarks create a brand new database, in either
-sequential, or random order. The "fillsync" benchmark flushes data
-from the operating system to the disk after every operation; the other
-write operations leave the data sitting in the operating system buffer
-cache for a while. The "overwrite" benchmark does random writes that
-update existing keys in the database.
-
- fillseq : 1.765 micros/op; 62.7 MB/s
- fillsync : 268.409 micros/op; 0.4 MB/s (10000 ops)
- fillrandom : 2.460 micros/op; 45.0 MB/s
- overwrite : 2.380 micros/op; 46.5 MB/s
-
-Each "op" above corresponds to a write of a single key/value pair.
-I.e., a random write benchmark goes at approximately 400,000 writes per second.
-
-Each "fillsync" operation costs much less (0.3 millisecond)
-than a disk seek (typically 10 milliseconds). We suspect that this is
-because the hard disk itself is buffering the update in its memory and
-responding before the data has been written to the platter. This may
-or may not be safe based on whether or not the hard disk has enough
-power to save its memory in the event of a power failure.
-
-## Read performance
-
-We list the performance of reading sequentially in both the forward
-and reverse direction, and also the performance of a random lookup.
-Note that the database created by the benchmark is quite small.
-Therefore the report characterizes the performance of leveldb when the
-working set fits in memory. The cost of reading a piece of data that
-is not present in the operating system buffer cache will be dominated
-by the one or two disk seeks needed to fetch the data from disk.
-Write performance will be mostly unaffected by whether or not the
-working set fits in memory.
-
- readrandom : 16.677 micros/op; (approximately 60,000 reads per second)
- readseq : 0.476 micros/op; 232.3 MB/s
- readreverse : 0.724 micros/op; 152.9 MB/s
-
-LevelDB compacts its underlying storage data in the background to
-improve read performance. The results listed above were done
-immediately after a lot of random writes. The results after
-compactions (which are usually triggered automatically) are better.
-
- readrandom : 11.602 micros/op; (approximately 85,000 reads per second)
- readseq : 0.423 micros/op; 261.8 MB/s
- readreverse : 0.663 micros/op; 166.9 MB/s
-
-Some of the high cost of reads comes from repeated decompression of blocks
-read from disk. If we supply enough cache to the leveldb so it can hold the
-uncompressed blocks in memory, the read performance improves again:
-
- readrandom : 9.775 micros/op; (approximately 100,000 reads per second before compaction)
- readrandom : 5.215 micros/op; (approximately 190,000 reads per second after compaction)
-
-## Repository contents
-
-See [doc/index.md](doc/index.md) for more explanation. See
-[doc/impl.md](doc/impl.md) for a brief overview of the implementation.
-
-The public interface is in include/*.h. Callers should not include or
-rely on the details of any other header files in this package. Those
-internal APIs may be changed without warning.
-
-Guide to header files:
-
-* **include/db.h**: Main interface to the DB: Start here
-
-* **include/options.h**: Control over the behavior of an entire database,
-and also control over the behavior of individual reads and writes.
-
-* **include/comparator.h**: Abstraction for user-specified comparison function.
-If you want just bytewise comparison of keys, you can use the default
-comparator, but clients can write their own comparator implementations if they
-want custom ordering (e.g. to handle different character encodings, etc.)
-
-* **include/iterator.h**: Interface for iterating over data. You can get
-an iterator from a DB object.
-
-* **include/write_batch.h**: Interface for atomically applying multiple
-updates to a database.
-
-* **include/slice.h**: A simple module for maintaining a pointer and a
-length into some other byte array.
-
-* **include/status.h**: Status is returned from many of the public interfaces
-and is used to report success and various kinds of errors.
-
-* **include/env.h**:
-Abstraction of the OS environment. A posix implementation of this interface is
-in util/env_posix.cc
-
-* **include/table.h, include/table_builder.h**: Lower-level modules that most
-clients probably won't use directly

-// Thread safety
-// -------------
-//
-// Writes require external synchronization, most likely a mutex.
-// Reads require a guarantee that the SkipList will not be destroyed
-// while the read is in progress. Apart from that, reads progress
-// without any internal locking or synchronization.
-//
-// Invariants:
-//
-// (1) Allocated nodes are never deleted until the SkipList is
-// destroyed. This is trivially guaranteed by the code since we
-// never delete any skip list nodes.
-//
-// (2) The contents of a Node except for the next/prev pointers are
-// immutable after the Node has been linked into the SkipList.
-// Only Insert() modifies the list, and it is careful to initialize
-// a node and use release-stores to publish the nodes in one or
-// more lists.
-//
-// ... prev vs. next pointer ordering ...

- C bindings for leveldb. May be useful as a stable ABI that can be
- used by programs that keep leveldb in a shared library, or for
- a JNI api.
-
- Does not support:
- . getters for the option types
- . custom comparators that implement key shortening
- . custom iter, db, env, cache implementations using just the C bindings
-
- Some conventions:
-
- (1) We expose just opaque struct pointers and functions to clients.
- This allows us to change internal representations without having to
- recompile clients.
-
- (2) For simplicity, there is no equivalent to the Slice type. Instead,
- the caller has to pass the pointer and length as separate
- arguments.
-
- (3) Errors are represented by a null-terminated c string. NULL
- means no error. All operations that can raise an error are passed
- a "char** errptr" as the last argument. One of the following must
- be true on entry:
- *errptr == NULL
- *errptr points to a malloc()ed null-terminated error message
- (On Windows, *errptr must have been malloc()-ed by this library.)
- On success, a leveldb routine leaves *errptr unchanged.
- On failure, leveldb frees the old value of *errptr and
- set *errptr to a malloc()ed error message.
-
- (4) Bools have the type unsigned char (0 == false; rest == true)
-
- (5) All of the pointer arguments must be non-NULL.

-// string. This helps reduce the space requirement significantly.
-// Furthermore, once every K keys, we do not apply the prefix

-// restart points, and can be used to do a binary search when looking
-// for a particular key. Values are stored as-is (without compression)
-// immediately following the corresponding key.
-//
-// An entry for a particular key-value pair has the form:
-// shared_bytes: varint32
-// unshared_bytes: varint32
-// value_length: varint32
-// key_delta: char[unshared_bytes]
-// value: char[value_length]

-//
-// The trailer of the block has the form:

-Nanopb - Protocol Buffers for Embedded Systems
-==============================================
-
-[](https://travis-ci.org/nanopb/nanopb)
-
-Nanopb is a small code-size Protocol Buffers implementation in ansi C. It is
-especially suitable for use in microcontrollers, but fits any memory
-restricted system.
-
-* **Homepage:** https://jpa.kapsi.fi/nanopb/
-* **Documentation:** https://jpa.kapsi.fi/nanopb/docs/
-* **Downloads:** https://jpa.kapsi.fi/nanopb/download/
-* **Forum:** https://groups.google.com/forum/#!forum/nanopb
-
-
-
-Using the nanopb library
-------------------------
-To use the nanopb library, you need to do two things:
-
-1. Compile your .proto files for nanopb, using protoc.
-2. Include pb_encode.c, pb_decode.c and pb_common.c in your project.
-
-The easiest way to get started is to study the project in "examples/simple".
-It contains a Makefile, which should work directly under most Linux systems.
-However, for any other kind of build system, see the manual steps in
-README.txt in that folder.
-
-
-
-Using the Protocol Buffers compiler (protoc)
---------------------------------------------
-The nanopb generator is implemented as a plugin for the Google's own protoc
-compiler. This has the advantage that there is no need to reimplement the
-basic parsing of .proto files. However, it does mean that you need the
-Google's protobuf library in order to run the generator.
-
-If you have downloaded a binary package for nanopb (either Windows, Linux or
-Mac OS X version), the 'protoc' binary is included in the 'generator-bin'
-folder. In this case, you are ready to go. Simply run this command:
-
- generator-bin/protoc --nanopb_out=. myprotocol.proto
-
-However, if you are using a git checkout or a plain source distribution, you
-need to provide your own version of protoc and the Google's protobuf library.
-On Linux, the necessary packages are protobuf-compiler and python-protobuf.
-On Windows, you can either build Google's protobuf library from source or use
-one of the binary distributions of it. In either case, if you use a separate
-protoc, you need to manually give the path to nanopb generator:
-
- protoc --plugin=protoc-gen-nanopb=nanopb/generator/protoc-gen-nanopb ...
-
-
-
-Running the tests
------------------
-If you want to perform further development of the nanopb core, or to verify
-its functionality using your compiler and platform, you'll want to run the
-test suite. The build rules for the test suite are implemented using Scons,
-so you need to have that installed. To run the tests:
-
- cd tests
- scons
-
-This will show the progress of various test cases. If the output does not
-end in an error, the test cases were successful.
-
-Note: Mac OS X by default aliases 'clang' as 'gcc', while not actually
-supporting the same command line options as gcc does. To run tests on
-Mac OS X, use: "scons CC=clang CXX=clang". Same way can be used to run
-tests with different compilers on any platform.
