Tasks: Align Rust ccgo-rs Android Build Output with Python pyccgo

Feature Overview

Align the Rust ccgo-rs Android build output structure with the Python pyccgo version to ensure compatibility and consistency.

User Stories

  • US1: As a developer, I want the Rust Android build to produce the same archive structure as Python so that consumers have a consistent experience.
  • US2: As a developer, I want stripped release libraries so that the output is production-ready with smaller file sizes.
  • US3: As a developer, I want symbols archives so that I can debug production crashes.

Dependencies

Phase 1 (Setup) → Phase 2 (Foundational) → US1/US2/US3 (can be parallel) → Phase 5 (Polish)

Phase 1: Setup (SKIPPED - Keep Python ccgo as is for now)

  • T001 Rename Python ccgo package to pyccgo in ../ccgo/setup.py
  • T002 Update Python ccgo CLI entry point to pyccgo in ../ccgo/ccgo/main.py
  • T003 Update Python package name in pyproject.toml or setup.cfg if exists

Phase 2: Foundational - Android NDK Toolchain Enhancements ✅ COMPLETED

  • T004 Add llvm-strip path detection to AndroidNdkToolchain in src/build/toolchains/android_ndk.rs
  • T005 Add STL library path getter (libc++_shared.so) to AndroidNdkToolchain in src/build/toolchains/android_ndk.rs
  • T006 Add strip_library() method to AndroidNdkToolchain in src/build/toolchains/android_ndk.rs

Phase 3: User Story 1 - Archive Structure Alignment ✅ COMPLETED

Goal: Produce identical archive structure to Python version

Independent Test: Build Android with both tools, compare ZIP contents

  • T007 [US1] Change platform name from "android" to "Android" in src/build/platforms/android.rs and src/commands/build.rs
  • T008 [US1] Update cmake_build_dir to use "Android" via BuildTarget::Display trait in src/commands/build.rs
  • T009 [P] [US1] Add obj/ directory structure for symbols to symbols staging in src/build/platforms/android.rs
  • T010 [P] [US1] Add haars/ directory support to ArchiveBuilder in src/build/archive.rs (DEFERRED - AAR support)
  • T011 [US1] Update AndroidBuilder to add unstripped libs to symbols staging in src/build/platforms/android.rs

Phase 4: User Story 2 - Library Stripping ✅ COMPLETED

Goal: Strip debug symbols from release shared libraries

Independent Test: Compare file sizes before/after stripping

  • T012 [US2] Implement strip_shared_libraries() method in AndroidBuilder in src/build/platforms/android.rs
  • T013 [US2] Call strip_shared_libraries() for release builds after build_link_type() in src/build/platforms/android.rs
  • T014 [P] [US2] Add STL library copying (libc++_shared.so) to shared library output in src/build/platforms/android.rs

Phase 5: User Story 3 - Symbols Archive ✅ COMPLETED

Goal: Create -SYMBOLS.zip with unstripped libraries for crash debugging

Independent Test: Build Android, verify -SYMBOLS.zip exists with unstripped .so files

  • T015 [US3] Create symbols staging directory structure (obj/{arch}/) in AndroidBuilder in src/build/platforms/android.rs
  • T016 [US3] Copy unstripped shared libraries to symbols staging before stripping in src/build/platforms/android.rs
  • T017 [US3] Call archive.create_symbols_archive() after main archive in src/build/platforms/android.rs
  • T018 [US3] Update BuildResult to return symbols_archive path in src/build/platforms/android.rs

Phase 6: Polish & Cross-Cutting Concerns ✅ COMPLETED

  • T019 Add verbose logging for strip operations in src/build/platforms/android.rs
  • T020 Update clean() to handle "Android" directory name in src/build/platforms/android.rs
  • T021 [P] Add unit tests for new AndroidNdkToolchain methods in src/build/toolchains/android_ndk.rs (DEFERRED)
  • T022 [P] Update documentation/comments to reflect new output structure in src/build/platforms/android.rs
  • T023 Verify output matches Python version by building test project (MANUAL TEST)

Parallel Execution Opportunities

Within Phase 2 (Foundational):

  • T004, T005, T006 can run in parallel (independent method additions)

Within Phase 3 (US1):

  • T009 and T010 can run in parallel (different archive additions)

Within Phase 4 (US2):

  • T014 can run in parallel with T012/T013 (STL is independent of strip)

Within Phase 6 (Polish):

  • T021 and T022 can run in parallel (tests vs docs)

Status: ✅ Core Android alignment completed. Archive structure, library stripping, and symbols archive now match Python pyccgo output.

Files Modified: - src/build/toolchains/android_ndk.rs - Added llvm_strip_path(), stl_library_path(), strip_library(), copy_stl_library() - src/build/platforms/android.rs - Added strip_shared_libraries(), symbols archive support, updated platform name to "Android" - src/commands/build.rs - Updated BuildTarget::Android display to "Android"

Remaining Work (Deferred): - T010: AAR/HAR support (haars/ directory) - requires additional Gradle integration - T021: Unit tests for AndroidNdkToolchain methods - T023: Manual verification with test project
