17 Commits • 7 Features
Oct 1, 2025October 2025 highlights across ooni/probe-multiplatform focused on delivering a more reliable, scalable, and user-friendly testing experience, while accelerating developer velocity through improved CI and test isolation. Key features delivered include an install-time OONI testing flow enabling tests to run directly from the install screen, facilitated by a RunSpecification builder and descriptor-based run creation. Dashboard UI was enhanced with collapsible descriptor sections and layout fixes, improving usability and information density on iOS. Onboarding reliability was improved by ensuring the Lottie animation completes before proceeding, reducing onboarding failures. Significant CI/Build performance gains were achieved through Kotlin Native/Gradle build caching and CocoaPods caching, speeding up iOS and multi-platform builds. Test run reliability was strengthened with a proxy availability check at run start, disabling the upload-only run worker at app startup, and running tests on a dedicated engine thread to improve isolation and stability.

Apr 1, 2025April 2025 (2025-04) monthly summary for ooni/probe-multiplatform focused on stability, maintainability, and user-centric enhancements across desktop and mobile. Delivered key packaging and runtime stability improvements, modernized notifications, richer platform UI, and data access capabilities, underpinned by targeted QA fixes and a formal release. Key outcomes: - Stabilized the build and packaging pipeline (engine packaging with conveyor, dependency handling, and desktop buildName fallback) reducing release risk. - Hardened run-time worker lifecycle (fixes for stopping multiple workers, Android background behavior, large input handling, and startup no-internet messaging). - Modernized notification flow (removed legacy setting; request permission only on Android) to simplify user experience and permissions model. - UI/Platform enhancements (unknown network type on desktop, dark splash on Android, desktop platform info, JavaFX WebView PoC) improving observability and polish. - Feature and QA improvements (Measurement raw data UI and upload, in-app language settings, test/QA fixes) plus a formal Release 5.0.6. Impact and value: - Higher reliability in builds and app/runtime behavior, faster release cycles, clearer user prompts, and richer data access for customers. The work strengthens cross-platform stability, observability, and maintainability for ongoing development. Technologies/skills demonstrated: - Kotlin/Java, Android and desktop UI patterns, JavaFX WebView, cross-platform packaging, dependency management, lint discipline, and targeted refactors (InstanceManager/DeepLinkParser) for maintainability.

Mar 1, 2025During March 2025, the team delivered across Android and desktop components with a focus on release automation, data reliability, and code quality. Key initiatives included updating and hardening the Google Play CI/CD release pipelines, enabling changelog uploads in publish workflows, and enhancing release tooling with fastlane improvements and locale handling. Data handling was improved by switching JSON processing to file-based keys, and core data submission was hardened to handle constraints, delete incomplete measurements, and gracefully ignore network errors. These changes reduced release friction, improved data quality, and heightened observability through instrumentation and logging. The work also included stability fixes for promotion workflows, version_code handling, and various quality improvements across UI, Kotlin lint, and navigation safety, underscoring a multi-platform, enterprise-grade release process.
