…ll` in `StorageReference`: This change will introduce stubbed versions of the `List()` and `ListAll()` methods to the C++ Firebase Storage SDK's `StorageReference` class. These methods are part of a feature to bring parity with the Firebase iOS and Android SDKs. Here are the key steps: - Define a `ListResult` struct in a new `firebase/storage/list_result.h` header file. This struct will hold the results of list operations. - Add `List(const char* page_token)`, `List()`, and `ListAll()` method declarations to `firebase/storage/storage_reference.h`. - Create stub implementations of these methods in `storage/src/common/storage_reference.cc`. These stubs will currently return a `Future` that resolves immediately with an empty `ListResult`. - Integrate with the existing `CleanupNotifier` and memory management system for Futures. - Add integration tests in `storage/integration_test/src/integration_test.cc` to verify the behavior of these stubbed methods. The tests will confirm that the methods return a successful Future with an empty `ListResult`. The actual implementation that calls the underlying iOS and Android SDKs will be done in a subsequent change.

Refactor ListResult to use Internal PIMPL pattern This change refactors the `firebase::storage::ListResult` class to use an internal ("PIMPL") pattern, aligning it with other classes in the Firebase C++ SDK, such as StorageReference and Metadata. This makes ListResult properly copyable and prepares it for future platform-specific implementations. Key changes include: 1. **`ListResultInternal` Base Class**: - Introduced an abstract base class `firebase::storage::internal::ListResultInternal`. - This class defines the internal interface for list results and includes a pure virtual `Clone()` method to support copyability. - It integrates with `CleanupNotifier` for lifecycle management. 2. **Platform-Specific `ListResultInternal` Stubs**: - Created stub implementations for Desktop, Android, and iOS: `ListResultDesktop`, `ListResultAndroid`, and `ListResultIOS`. - Each implements the `ListResultInternal` interface, returning empty data for the stubs, and implements the `Clone()` method. 3. **Public `ListResult` Class Refactoring**: - The public `ListResult` class now holds an `InternalUniquePtr` to a `ListResultInternal` object. - It's now fully copyable (using `ListResultInternal::Clone()`) and movable. - Accessors delegate to the internal implementation. 4. **`StorageReferenceInternal` Factory Method**: - Added a virtual method `CreateListResultInternal()` to each platform-specific `StorageReferenceInternal` class (Desktop, Android, iOS). - This method is responsible for creating the correct platform-specific `ListResultInternal` instance. 5. **`StorageReference` Common Code Update**: - The common `StorageReference::List()` and `StorageReference::ListAll()` methods now call `internal_->CreateListResultInternal()` to obtain the `ListResultInternal` object, ensuring platform-correct instantiation. 6. **Integration Tests**: - Reviewed and confirmed that existing integration tests for list operations are compatible with these changes. Missing tests due to previous environment resets were restored. This refactoring does not change the external behavior of the stubbed `List` and `ListAll` methods but provides a more robust and consistent internal structure. Output: I've refactored `ListResult` to use the Internal PIMPL pattern. This change refactors your `firebase::storage::ListResult` class to use an internal ("PIMPL") pattern, aligning it with other classes in the Firebase C++ SDK, such as StorageReference and Metadata. This makes ListResult properly copyable and prepares it for future platform-specific implementations. Key changes include: 1. **`ListResultInternal` Base Class**: - I introduced an abstract base class `firebase::storage::internal::ListResultInternal`. - This class defines the internal interface for list results and includes a pure virtual `Clone()` method to support copyability. - It integrates with `CleanupNotifier` for lifecycle management. 2. **Platform-Specific `ListResultInternal` Stubs**: - I created stub implementations for Desktop, Android, and iOS: `ListResultDesktop`, `ListResultAndroid`, and `ListResultIOS`. - Each implements the `ListResultInternal` interface, returning empty data for the stubs, and implements the `Clone()` method. 3. **Public `ListResult` Class Refactoring**: - Your public `ListResult` class now holds an `InternalUniquePtr` to a `ListResultInternal` object. - It's now fully copyable (using `ListResultInternal::Clone()`) and movable. - Accessors delegate to the internal implementation. 4. **`StorageReferenceInternal` Factory Method**: - I added a virtual method `CreateListResultInternal()` to each platform-specific `StorageReferenceInternal` class (Desktop, Android, iOS). - This method is responsible for creating the correct platform-specific `ListResultInternal` instance. 5. **`StorageReference` Common Code Update**: - The common `StorageReference::List()` and `StorageReference::ListAll()` methods now call `internal_->CreateListResultInternal()` to obtain the `ListResultInternal` object, ensuring platform-correct instantiation. 6. **Integration Tests**: - I reviewed and confirmed that existing integration tests for list operations are compatible with these changes. Missing tests due to previous environment resets were restored. This refactoring does not change the external behavior of the stubbed `List` and `ListAll` methods but provides a more robust and consistent internal structure.

feat: Add stub List/ListAll methods with corrected PIMPL pattern This commit introduces stub implementations for StorageReference's `List()` and `ListAll()` methods in the Firebase C++ Storage SDK. It follows a corrected PIMPL (pointer to implementation) pattern for the `ListResult` class, strictly adhering to the internal architecture observed in classes like `firebase::storage::Metadata` and its `MetadataInternalCommon` helper. This version addresses feedback from previous attempts and ensures: 1. **`ListResultInternalCommon` as Static Helpers**: - A class `firebase::storage::internal::ListResultInternalCommon` is defined within `storage/src/common/list_result.cc`. - It contains only static methods responsible for managing the lifecycle (cleanup registration, PIMPL deletion) of `ListResult`'s internal implementation. This mirrors `MetadataInternalCommon`. 2. **Platform-Specific `ListResultInternal`**: - Each platform (Desktop, Android, iOS) defines its own concrete `firebase::storage::internal::ListResultInternal` class. - These are located in files like `storage/src/desktop/list_result_desktop.h` (and `.cc`), `storage/src/android/list_result_android.h` (and `.cc`), and `storage/src/ios/list_result_ios.h` (and `.mm`). - These classes hold the stub data (empty item/prefix lists, empty page token) and a pointer to their platform's `StorageReferenceInternal` for context (primarily for cleanup). - They provide a copy constructor for `ListResult`'s copy operations. - They do not inherit from a common PIMPL base class. 3. **Public `ListResult` Refactoring**: - The public `firebase::storage::ListResult` class now holds a raw pointer (`internal::ListResultInternal* internal_`) to its platform-specific PIMPL object. - Its constructors, destructor, copy, and move assignment operators utilize the static helper methods in `ListResultInternalCommon` to manage the `internal_` pointer's lifecycle and cleanup registration, similar to how `Metadata` manages its `internal_`. 4. **`StorageReference` Methods Update**: - `StorageReference::ListAll()` and `StorageReference::List()` in `storage/src/common/storage_reference.cc` now correctly create `ListResult` instances. They instantiate the appropriate platform-specific `internal::ListResultInternal` via a direct `new internal::ListResultInternal(...)` call (relying on the build system to link the correct platform's implementation) and pass this PIMPL object to a private constructor of `ListResult`. 5. **Build System**: - `storage/CMakeLists.txt` was updated to include the correctly named platform-specific source files (e.g., `list_result_desktop.cc`). 6. **Integration Tests**: - Existing integration tests were reviewed and confirmed to be compatible with these internal changes. This implementation provides the `List` and `ListAll` API as stubs, returning empty results, with a robust internal structure that aligns with the SDK's established PIMPL and lifecycle management patterns.

This commit removes verbose and development-process-related comments that I added during the implementation of the StorageReference List/ListAll stubs and the ListResult PIMPL refactoring. The cleanup pass focused on: - Removing overly detailed explanations of PIMPL strategy. - Deleting notes to myself (TODOs, iterative thoughts). - Condensing comments on includes and standard C++ features. - Ensuring Doxygen comments in public headers are concise and accurate. - Preserving all pre-existing comments in the codebase. Files affected by this cleanup include: - storage/src/common/list_result.cc - storage/src/desktop/list_result_desktop.h - storage/src/desktop/list_result_desktop.cc - storage/src/android/list_result_android.h - storage/src/android/list_result_android.cc - storage/src/ios/list_result_ios.h - storage/src/ios/list_result_ios.mm - storage/src/include/firebase/storage/list_result.h - storage/src/common/storage_reference.cc This change improves code readability and maintainability by ensuring comments are purposeful and do not reflect the iterative generation process. No functional code changes are included in this commit.

This commit removes explanatory comments I added on the same line as #include directives in various files related to the ListResult feature. These comments were deemed unnecessary as the purpose of the includes is generally clear from context or the header filename itself. This cleanup enhances code readability by reducing clutter in the include blocks. No functional code changes are included. Files affected: - storage/src/common/list_result.cc - storage/src/desktop/list_result_desktop.h - storage/src/android/list_result_android.h - storage/src/ios/list_result_ios.h - storage/src/common/storage_reference.cc (And potentially platform .cc/.mm files for list_result if any same-line include comments were found and removed there, though I found none for those.)

StorageReference::ListAll() methods and associated ListResult class. It incorporates extensive refactoring based on detailed code review feedback to align with established Firebase C++ SDK patterns, particularly the PIMPL (Pointer to Implementation) strategy observed in classes like Metadata. Key changes and fixes in this version: 1. **PIMPL Pattern for `List` and `ListAll` Methods**: - The core logic for `List()` and `ListAll()` (including Future creation and ListResult PIMPL instantiation) has been moved into the platform-specific `StorageReferenceInternal` classes (Desktop, Android, iOS). - The public `StorageReference::List()` and `StorageReference::ListAll()` methods in `storage/src/common/storage_reference.cc` now simply delegate to these internal implementations (e.g., `internal_->ListAll()`). 2. **`ListResult` PIMPL Implementation (Metadata Pattern)**: - The public `firebase::storage::ListResult` class holds a raw pointer (`internal::ListResultInternal* internal_`) to its platform-specific PIMPL object. - A static helper class `firebase::storage::internal::ListResultInternalCommon` (defined in `storage/src/common/list_result.cc`) manages the lifecycle (cleanup registration, PIMPL deletion) of this raw pointer, mirroring the `MetadataInternalCommon` pattern. - Each platform (Desktop, Android, iOS) defines its own concrete `firebase::storage::internal::ListResultInternal` class in its respective directory (e.g., `storage/src/desktop/list_result_desktop.h`). These classes hold the stub data and context. - The `ListResult` constructors, destructor, and copy/move operations use `ListResultInternalCommon` static methods for PIMPL management. 3. **Doxygen Documentation**: - Added missing Doxygen comments for `ListResult::items()`, `ListResult::prefixes()`, `ListResult::page_token()`, and `ListResult::is_valid()` in `storage/src/include/firebase/storage/list_result.h`. 4. **Method Naming Correction**: - Renamed `ListResultInternalCommon::DeleteInternalPimpl` to `ListResultInternalCommon::DeleteInternal` in `storage/src/common/list_result.cc` and updated all its call sites. 5. **Comment Cleanup**: - Addressed various pieces of feedback regarding comments: - Reverted an unintentional change to a comment in `storage/src/common/storage_reference.cc`. - Removed leftover/stale comments related to previous refactoring steps in `storage/src/ios/storage_reference_ios.h`. - (A reported comment in `storage/src/ios/storage_reference_ios.mm` was found to be a necessary include with an accurate comment after the PIMPL refactoring of List/ListAll into platform internals). - General cleanup of verbose agent-added comments was performed in previous commits. This version should now correctly implement the feature request with the intended architecture and address all raised review points.
