From 95a599005f19324b47aaf268b3f770df0d95c6d6 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 14 Jun 2025 20:57:45 +0000 Subject: [PATCH 01/11] Here's the plan for adding stub implementations for `List` and `ListAll` 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. --- .../integration_test/src/integration_test.cc | 72 +++++++++++++++++++ storage/src/common/storage_reference.cc | 36 ++++++++++ .../include/firebase/storage/list_result.h | 40 +++++++++++ .../firebase/storage/storage_reference.h | 1 + 4 files changed, 149 insertions(+) create mode 100644 storage/src/include/firebase/storage/list_result.h diff --git a/storage/integration_test/src/integration_test.cc b/storage/integration_test/src/integration_test.cc index f430de37de..95e7b6f951 100644 --- a/storage/integration_test/src/integration_test.cc +++ b/storage/integration_test/src/integration_test.cc @@ -26,6 +26,7 @@ #include "firebase/auth.h" #include "firebase/internal/platform.h" #include "firebase/storage.h" +#include "firebase/storage/list_result.h" #include "firebase/util.h" #include "firebase_test_framework.h" // NOLINT @@ -1622,4 +1623,75 @@ TEST_F(FirebaseStorageTest, TestInvalidatingReferencesWhenDeletingApp) { InitializeAppAndAuth();

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.

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. --- storage/CMakeLists.txt | 9 +- storage/src/android/list_result_android.cc | 21 ++ storage/src/android/list_result_android.h | 46 ++++ .../src/android/storage_reference_android.cc | 8 +- .../src/android/storage_reference_android.h | 6 +- storage/src/common/list_result.cc | 230 ++++++++++++++---- storage/src/common/list_result_internal.h | 78 ------ storage/src/common/storage_reference.cc | 38 ++- storage/src/desktop/list_result_desktop.cc | 34 +++ storage/src/desktop/list_result_desktop.h | 65 +++++ .../src/desktop/storage_reference_desktop.cc | 4 - .../src/desktop/storage_reference_desktop.h | 2 - .../include/firebase/storage/list_result.h | 77 +++--- storage/src/ios/list_result_ios.h | 33 ++- storage/src/ios/list_result_ios.mm | 45 +--- storage/src/ios/storage_reference_ios.h | 6 +- storage/src/ios/storage_reference_ios.mm | 8 +- 17 files changed, 457 insertions(+), 253 deletions(-) create mode 100644 storage/src/android/list_result_android.cc create mode 100644 storage/src/android/list_result_android.h delete mode 100644 storage/src/common/list_result_internal.h create mode 100644 storage/src/desktop/list_result_desktop.cc create mode 100644 storage/src/desktop/list_result_desktop.h diff --git a/storage/CMakeLists.txt b/storage/CMakeLists.txt index e2fd88e72f..d768e8503a 100644 --- a/storage/CMakeLists.txt +++ b/storage/CMakeLists.txt @@ -38,7 +38,8 @@ set(android_SRCS src/android/controller_android.cc src/android/metadata_android.cc src/android/storage_android.cc - src/android/storage_reference_android.cc) + src/android/storage_reference_android.cc + src/android/list_result_android.cc) # Source files used by the iOS implementation. set(ios_SRCS @@ -47,7 +48,8 @@ set(ios_SRCS src/ios/metadata_ios.mm src/ios/storage_ios.mm src/ios/storage_reference_ios.mm - src/ios/util_ios.mm) + src/ios/util_ios.mm + src/ios/list_result_ios.mm) # Source files used by the desktop implementation. set(desktop_SRCS @@ -58,7 +60,8 @@ set(desktop_SRCS src/desktop/rest_operation.cc src/desktop/storage_desktop.cc src/desktop/storage_path.cc - src/desktop/storage_reference_desktop.cc) + src/desktop/storage_reference_desktop.cc + src/desktop/list_result_desktop.cc) if(ANDROID) set(storage_platform_SRCS diff --git a/storage/src/android/list_result_android.cc b/storage/src/android/list_result_android.cc new file mode 100644 index 0000000000..9115c75de7 --- /dev/null +++ b/storage/src/android/list_result_android.cc @@ -0,0 +1,21 @@ +// File: storage/src/android/list_result_android.cc +#include "storage/src/android/list_result_android.h" + +namespace firebase { +namespace storage { +namespace internal { + +ListResultInternal::ListResultInternal( + StorageReferenceInternal* platform_sri, + const ListResultInternal* other_to_copy_from) + : platform_sri_(platform_sri) { + if (other_to_copy_from) { + items_ = other_to_copy_from->items_; + prefixes_ = other_to_copy_from->prefixes_; + page_token_ = other_to_copy_from->page_token_; + } +} + +} // namespace internal +} // namespace storage +} // namespace firebase diff --git a/storage/src/android/list_result_android.h b/storage/src/android/list_result_android.h new file mode 100644 index 0000000000..661ecc0d5f --- /dev/null +++ b/storage/src/android/list_result_android.h @@ -0,0 +1,46 @@ +// File: storage/src/android/list_result_android.h +#ifndef FIREBASE_STORAGE_CLIENT_CPP_SRC_ANDROID_LIST_RESULT_ANDROID_H_ +#define FIREBASE_STORAGE_CLIENT_CPP_SRC_ANDROID_LIST_RESULT_ANDROID_H_ + +#include +#include + +#include "firebase/storage/storage_reference.h" +#include "storage/src/android/storage_reference_android.h" // Defines firebase::storage::internal::StorageReferenceInternal for android +#include "storage/src/android/storage_internal_android.h" // Defines firebase::storage::internal::StorageInternal for android + +namespace firebase { +namespace storage { +namespace internal { + +class ListResultInternal { + public: + explicit ListResultInternal( + StorageReferenceInternal* platform_sri, + const ListResultInternal* other_to_copy_from = nullptr); + + const std::vector& items() const { return items_; } + const std::vector& prefixes() const { return prefixes_; } + const std::string& page_token() const { return page_token_; } + + StorageReferenceInternal* storage_reference_internal() const { + return platform_sri_; + } + StorageInternal* associated_storage_internal() const { + return platform_sri_ ?

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.

<161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 17 Jun 2025 00:31:13 +0000 Subject: [PATCH 06/11] This commit implements the stubbed StorageReference::List() and 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. --- .../src/android/storage_reference_android.cc | 35 +++++++++++++++- .../src/android/storage_reference_android.h | 5 ++- storage/src/common/list_result.cc | 10 ++--- storage/src/common/storage_reference.cc | 42 ++++++------------- .../src/desktop/storage_reference_desktop.cc | 36 ++++++++++++++++ .../src/desktop/storage_reference_desktop.h | 3 ++ .../include/firebase/storage/list_result.h | 13 ++++-- storage/src/ios/storage_reference_ios.h | 5 ++- storage/src/ios/storage_reference_ios.mm | 35 +++++++++++++++- 9 files changed, 141 insertions(+), 43 deletions(-) diff --git a/storage/src/android/storage_reference_android.cc b/storage/src/android/storage_reference_android.cc index 38265c4caf..a1c35b6db2 100644 --- a/storage/src/android/storage_reference_android.cc +++ b/storage/src/android/storage_reference_android.cc @@ -23,9 +23,11 @@ #include "app/src/include/firebase/app.h" #include "app/src/util_android.h" #include "storage/src/android/controller_android.h" -// Removed: #include "storage/src/android/list_result_android.h" +#include "storage/src/android/list_result_android.h" // Defines the android internal::ListResultInternal #include "storage/src/android/metadata_android.h" #include "storage/src/android/storage_android.h" +// firebase/storage/storage_reference.h is included via storage_reference_android.h +// app/src/future_manager.h is included via storage_reference_android.h -> reference_counted_future_impl.h #include "storage/src/include/firebase/storage.h" #include "storage/src/include/firebase/storage/common.h" #include "storage/storage_resources.h" @@ -735,6 +737,37 @@ jint StorageReferenceInternal::CppByteUploaderReadBytes( return data_read; } +Future StorageReferenceInternal::ListAll() { + StorageReference self(this); // Public self for future context + ReferenceCountedFutureImpl* ref_future = + future()->Alloc(kStorageReferenceFnCount); + Future future = MakeFuture(ref_future, self); + + internal::ListResultInternal* list_pimpl = + new internal::ListResultInternal(this, nullptr); // 'this' is StorageReferenceInternal* (Android) + + ListResult result_to_complete(list_pimpl); + + ref_future->Complete(self.AsHandle(), kErrorNone, "", result_to_complete); + return future; +} + +Future StorageReferenceInternal::List(const char* page_token) { + StorageReference self(this); // Public self for future context + ReferenceCountedFutureImpl* ref_future = + future()->Alloc(kStorageReferenceFnCount); + Future future = MakeFuture(ref_future, self); + + // page_token is ignored for stub. + internal::ListResultInternal* list_pimpl = + new internal::ListResultInternal(this, nullptr); + + ListResult result_to_complete(list_pimpl); + + ref_future->Complete(self.AsHandle(), kErrorNone, "", result_to_complete); + return future; +} + } // namespace internal } // namespace storage } // namespace firebase diff --git a/storage/src/android/storage_reference_android.h b/storage/src/android/storage_reference_android.h index a77feaa29b..7098cff4e1 100644 --- a/storage/src/android/storage_reference_android.h +++ b/storage/src/android/storage_reference_android.h @@ -23,8 +23,8 @@ #include "app/src/reference_counted_future_impl.h" #include "app/src/util_android.h" #include "storage/src/android/storage_android.h" -// Removed: #include "storage/src/common/list_result_internal.h" #include "storage/src/include/firebase/storage/storage_reference.h" +#include "firebase/storage/list_result.h" // Added for ListResult return type namespace firebase { namespace storage { @@ -154,6 +154,9 @@ class StorageReferenceInternal { // StorageInternal instance we are associated with.

Key changes include: 1. **PIMPL Pattern for `List` and `ListAll` Methods**: - The core logic for `List()` and `ListAll()`, including Future creation and `ListResultInternal` PIMPL instantiation, has been moved from common `StorageReference` code into the platform-specific `StorageReferenceInternal` classes (Desktop, Android, iOS). - Public `StorageReference::List()` and `StorageReference::ListAll()` now correctly delegate to these internal methods. 2. **Doxygen Documentation**: - Added comprehensive Doxygen comments for `ListResult::items()`, `ListResult::prefixes()`, `ListResult::page_token()`, and `ListResult::is_valid()` in `storage/src/include/firebase/storage/list_result.h`, addressing previous warnings. 3. **Method Naming Correction**: - Renamed the static helper method `ListResultInternalCommon::DeleteInternalPimpl` to `ListResultInternalCommon::DeleteInternal` in `storage/src/common/list_result.cc` and updated its call sites for consistency. 4. **Comment Cleanup and Correction**: - Reverted an unintentional change to a pre-existing comment in `storage/src/common/storage_reference.cc`. - Removed various extraneous or outdated comments from: - `storage/src/ios/storage_reference_ios.h` - `storage/src/android/storage_reference_android.cc` - `storage/src/android/storage_reference_android.h` - A previously flagged comment in `storage/src/ios/storage_reference_ios.mm` was re-verified and found to be a necessary include with an accurate comment after architectural changes. These changes address the specific points raised in the code review, improving code structure, documentation, and cleanliness. --- .../src/android/storage_reference_android.cc | 2 -- .../src/android/storage_reference_android.h | 2 +- .../include/firebase/storage/list_result.h | 29 ++++++++++--------- 3 files changed, 17 insertions(+), 16 deletions(-) diff --git a/storage/src/android/storage_reference_android.cc b/storage/src/android/storage_reference_android.cc index a1c35b6db2..89583db5d1 100644 --- a/storage/src/android/storage_reference_android.cc +++ b/storage/src/android/storage_reference_android.cc @@ -26,8 +26,6 @@ #include "storage/src/android/list_result_android.h" // Defines the android internal::ListResultInternal #include "storage/src/android/metadata_android.h" #include "storage/src/android/storage_android.h" -// firebase/storage/storage_reference.h is included via storage_reference_android.h -// app/src/future_manager.h is included via storage_reference_android.h -> reference_counted_future_impl.h #include "storage/src/include/firebase/storage.h" #include "storage/src/include/firebase/storage/common.h" #include "storage/storage_resources.h" diff --git a/storage/src/android/storage_reference_android.h b/storage/src/android/storage_reference_android.h index 7098cff4e1..0c2d925831 100644 --- a/storage/src/android/storage_reference_android.h +++ b/storage/src/android/storage_reference_android.h @@ -24,7 +24,7 @@ #include "app/src/util_android.h" #include "storage/src/android/storage_android.h" #include "storage/src/include/firebase/storage/storage_reference.h" -#include "firebase/storage/list_result.h" // Added for ListResult return type +#include "firebase/storage/list_result.h" namespace firebase { namespace storage { diff --git a/storage/src/include/firebase/storage/list_result.h b/storage/src/include/firebase/storage/list_result.h index b9f9fcdd80..9128afb3c8 100644 --- a/storage/src/include/firebase/storage/list_result.h +++ b/storage/src/include/firebase/storage/list_result.h @@ -59,25 +59,28 @@ class SWIG_STORAGE_EXPORT ListResult { /// @brief Destructor. ~ListResult(); - /// @brief Gets the list of items (files) found by the list operation. - /// @return A const reference to a vector of StorageReferences representing - /// the items.

From b0050f00a7d0141d2e7f76fb8df7f342d442d177 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 17 Jun 2025 23:50:20 +0000 Subject: [PATCH 10/11] Fix: Correct include path for list_result.h in StorageReferenceInternal This commit corrects the #include path for the public `firebase/storage/list_result.h` header within the desktop platform's `StorageReferenceInternal` implementation (`storage/src/desktop/storage_reference_desktop.cc`). I changed the path from a relative "firebase/storage/list_result.h" to a more explicit "storage/src/include/firebase/storage/list_result.h" to resolve a potential build issue. Include paths for Android and iOS platforms were reviewed and found to be correctly handling the inclusion of `firebase/storage/list_result.h` via their respective `StorageReferenceInternal` header files using standard include paths. Additionally, I removed a minor extraneous agent-added comment from `storage/src/ios/storage_reference_ios.h`. I ran the code formatting script after these changes. --- .../integration_test/src/integration_test.cc | 19 +++--- storage/src/android/list_result_android.h | 2 +- .../src/android/storage_reference_android.cc | 10 +-- .../src/android/storage_reference_android.h | 2 +- storage/src/common/list_result.cc | 64 +++++++++++-------- storage/src/common/storage_reference.cc | 2 +- storage/src/desktop/list_result_desktop.cc | 6 +- storage/src/desktop/list_result_desktop.h | 22 ++++--- .../src/desktop/storage_reference_desktop.cc | 14 ++-- .../include/firebase/storage/list_result.h | 12 ++-- storage/src/ios/storage_reference_ios.h | 2 +- 11 files changed, 92 insertions(+), 63 deletions(-) diff --git a/storage/integration_test/src/integration_test.cc b/storage/integration_test/src/integration_test.cc index 95e7b6f951..dd86c32fb0 100644 --- a/storage/integration_test/src/integration_test.cc +++ b/storage/integration_test/src/integration_test.cc @@ -1624,11 +1624,12 @@ TEST_F(FirebaseStorageTest, TestInvalidatingReferencesWhenDeletingApp) { } // Test the StorageReference::ListAll() method. -// This test currently only verifies that the stubbed method returns an empty result. +// This test currently only verifies that the stubbed method returns an empty +// result.
