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.

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> diff --git a/StoneIsland/platforms/ios/Pods/GoogleUtilities/GoogleUtilities/Logger/GULLogger.m b/StoneIsland/platforms/ios/Pods/GoogleUtilities/GoogleUtilities/Logger/GULLogger.m new file mode 100644 index 00000000..7ad44050 --- /dev/null +++ b/StoneIsland/platforms/ios/Pods/GoogleUtilities/GoogleUtilities/Logger/GULLogger.m @@ -0,0 +1,221 @@ +// Copyright 2018 Google +// +// Licensed under the Apache License, Version 2.0 (the "License"); +// you may not use this file except in compliance with the License. +// You may obtain a copy of the License at +// +// http://www.apache.org/licenses/LICENSE-2.0 +// +// Unless required by applicable law or agreed to in writing, software +// distributed under the License is distributed on an "AS IS" BASIS, +// WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +// See the License for the specific language governing permissions and +// limitations under the License. + +#if SWIFT_PACKAGE +// Need to import the public header here, since the module won't exist yet. +// Restructure the GULLogger headers for Firebase 7. +#import "GoogleUtilities/Logger/Public/GULLoggerLevel.h" +#endif + +#import "GoogleUtilities/Logger/Private/GULLogger.h" + +#include <asl.h> + +#import "GoogleUtilities/Environment/Private/GULAppEnvironmentUtil.h" +#import "GoogleUtilities/Logger/Public/GULLoggerLevel.h" + +/// ASL client facility name used by GULLogger. +const char *kGULLoggerASLClientFacilityName = "com.google.utilities.logger"; + +static dispatch_once_t sGULLoggerOnceToken; + +static aslclient sGULLoggerClient; + +static dispatch_queue_t sGULClientQueue; + +static BOOL sGULLoggerDebugMode; + +static GULLoggerLevel sGULLoggerMaximumLevel; + +// Allow clients to register a version to include in the log. +static const char *sVersion = ""; + +static GULLoggerService kGULLoggerLogger = @"[GULLogger]"; + +#ifdef DEBUG +/// The regex pattern for the message code. +static NSString *const kMessageCodePattern = @"^I-[A-Z]{3}[0-9]{6}$"; +static NSRegularExpression *sMessageCodeRegex; +#endif + +void GULLoggerInitializeASL(void) { + dispatch_once(&sGULLoggerOnceToken, ^{ + NSInteger majorOSVersion = [[GULAppEnvironmentUtil systemVersion] integerValue]; + uint32_t aslOptions = ASL_OPT_STDERR; +#if TARGET_OS_SIMULATOR + // The iOS 11 simulator doesn't need the ASL_OPT_STDERR flag. + if (majorOSVersion >= 11) { + aslOptions = 0; + } +#else + // Devices running iOS 10 or higher don't need the ASL_OPT_STDERR flag. + if (majorOSVersion >= 10) { + aslOptions = 0; + } +#endif // TARGET_OS_SIMULATOR + +#pragma clang diagnostic push +#pragma clang diagnostic ignored "-Wdeprecated-declarations" // asl is deprecated + // Initialize the ASL client handle. + sGULLoggerClient = asl_open(NULL, kGULLoggerASLClientFacilityName, aslOptions); + sGULLoggerMaximumLevel = GULLoggerLevelNotice; + + // Set the filter used by system/device log.

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). + +### Managing Headers and Imports + +See [HeadersImports.md](HeadersImports.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`: + +``` +brew install clang-format +brew install swiftformat +``` + +### 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 add it to the Xcode project. + +## 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 + +The Firebase Database Integration tests can be run against a locally running Database Emulator +or against a production instance. + +To run against a local emulator instance, invoke `./scripts/run_database_emulator.sh start` before +running the integration test. + +To run against a production instance, provide a valid GoogleServices-Info.plist and copy it to +`FirebaseDatabase/Tests/Resources/GoogleService-Info.plist`. Your Security Rule must be set to +[public](https://firebase.google.com/docs/database/security/quickstart) while your tests are +running. + +### 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. + +## Contributing + +See [Contributing](CONTRIBUTING.md) for more information on contributing to the Firebase +iOS SDK. + +## License + +The contents of this repository is licensed under the +[Apache License, version 2.0](http://www.apache.org/licenses/LICENSE-2.0). + +Your use of Firebase is governed by the +[Terms of Service for Firebase Services](https://firebase.google.com/terms/). + +[gh-actions]: https://github.com/firebase/firebase-ios-sdk/actions +[gh-abtesting-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/abtesting/badge.svg +[gh-appdistribution-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/appdistribution/badge.svg +[gh-auth-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/auth/badge.svg +[gh-core-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/core/badge.svg +[gh-crashlytics-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/crashlytics/badge.svg +[gh-database-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/database/badge.svg +[gh-datatransport-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/datatransport/badge.svg +[gh-dynamiclinks-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/dynamiclinks/badge.svg +[gh-firebasepod-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firebasepod/badge.svg +[gh-firestore-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/firestore/badge.svg +[gh-functions-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/functions/badge.svg +[gh-inappmessaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/inappmessaging/badge.svg +[gh-interop-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/interop/badge.svg +[gh-messaging-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/messaging/badge.svg +[gh-remoteconfig-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/remoteconfig/badge.svg +[gh-storage-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/storage/badge.svg +[gh-symbolcollision-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/symbolcollision/badge.svg +[gh-zip-badge]: https://github.com/firebase/firebase-ios-sdk/workflows/zip/badge.svg |
