From 5e9fc6b530bb733685f176675d8081e6defca931 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 9 Jun 2025 19:24:44 +0000 Subject: [PATCH 1/7] feat: Implement List and ListAll API for StorageReference Adds the `List(max_results, page_token)` and `ListAll()` methods to the `firebase::storage::StorageReference` C++ API. These methods allow you to list objects and common prefixes (directories) within a storage location. Features: - Paginated listing using `List(max_results, page_token)`. - Comprehensive listing using `ListAll()`. - Returns a `Future`, where `ListResult` contains a list of `StorageReference` objects for items and prefixes, and a page token for continuation. - Implemented for Android by calling the underlying Firebase Android SDK's list operations via JNI. - Implemented for iOS by calling the underlying Firebase iOS SDK's list operations. - Desktop platform provides stubs that return `kErrorUnimplemented`. - Includes comprehensive integration tests covering various scenarios such as basic listing, pagination, empty folders, and listing non-existent paths. --- storage/CMakeLists.txt | 4 + .../integration_test/src/integration_test.cc | 282 +++++++++++++++++- storage/src/android/list_result_android.cc | 202 +++++++++++++ storage/src/android/list_result_android.h | 101 +++++++ .../src/android/storage_reference_android.cc | 111 ++++++- .../src/android/storage_reference_android.h | 10 + storage/src/common/list_result.cc | 212 +++++++++++++ .../src/common/list_result_internal_common.h | 68 +++++ storage/src/common/storage_reference.cc | 30 ++ storage/src/desktop/list_result_desktop.cc | 58 ++++ storage/src/desktop/list_result_desktop.h | 94 ++++++ .../src/desktop/storage_reference_desktop.cc | 38 +++ .../src/desktop/storage_reference_desktop.h | 11 + .../include/firebase/storage/list_result.h | 83 ++++++ .../firebase/storage/storage_reference.h | 56 ++++ .../src/ios/fir_storage_list_result_pointer.h | 40 +++ storage/src/ios/list_result_ios.h | 102 +++++++ storage/src/ios/list_result_ios.mm | 123 ++++++++ storage/src/ios/storage_reference_ios.h | 10 + storage/src/ios/storage_reference_ios.mm | 88 ++++++ 20 files changed, 1720 insertions(+), 3 deletions(-) create mode 100644 storage/src/android/list_result_android.cc create mode 100644 storage/src/android/list_result_android.h create mode 100644 storage/src/common/list_result.cc create mode 100644 storage/src/common/list_result_internal_common.h create mode 100644 storage/src/desktop/list_result_desktop.cc create mode 100644 storage/src/desktop/list_result_desktop.h create mode 100644 storage/src/include/firebase/storage/list_result.h create mode 100644 storage/src/ios/fir_storage_list_result_pointer.h create mode 100644 storage/src/ios/list_result_ios.h create mode 100644 storage/src/ios/list_result_ios.mm diff --git a/storage/CMakeLists.txt b/storage/CMakeLists.txt index e2fd88e72f..e4a722fd9f 100644 --- a/storage/CMakeLists.txt +++ b/storage/CMakeLists.txt @@ -19,6 +19,7 @@ set(common_SRCS src/common/common.cc src/common/controller.cc src/common/listener.cc + src/common/list_result.cc src/common/metadata.cc src/common/storage.cc src/common/storage_reference.cc @@ -36,6 +37,7 @@ binary_to_array("storage_resources" set(android_SRCS ${storage_resources_source} src/android/controller_android.cc + src/android/list_result_android.cc src/android/metadata_android.cc src/android/storage_android.cc src/android/storage_reference_android.cc) @@ -44,6 +46,7 @@ set(android_SRCS set(ios_SRCS src/ios/controller_ios.mm src/ios/listener_ios.mm + src/ios/list_result_ios.mm src/ios/metadata_ios.mm src/ios/storage_ios.mm src/ios/storage_reference_ios.mm @@ -54,6 +57,7 @@ set(desktop_SRCS src/desktop/controller_desktop.cc src/desktop/curl_requests.cc src/desktop/listener_desktop.cc + src/desktop/list_result_desktop.cc src/desktop/metadata_desktop.cc src/desktop/rest_operation.cc src/desktop/storage_desktop.cc diff --git a/storage/integration_test/src/integration_test.cc b/storage/integration_test/src/integration_test.cc index f430de37de..c306309e96 100644 --- a/storage/integration_test/src/integration_test.cc +++ b/storage/integration_test/src/integration_test.cc @@ -20,6 +20,7 @@ #include #include #include // NOLINT +#include // For std::vector in list tests #include "app_framework.h" // NOLINT #include "firebase/app.h" @@ -80,6 +81,9 @@ using app_framework::PathForResource;

Here's a summary of the changes: - Integration Tests: - I removed `SKIP_TEST_ON_ANDROID_EMULATOR` from the `ListAllBasic` and `ListPaginated` tests. - I refactored the list tests so they create their own unique root folders instead of using a shared one in the test fixture. This improves test isolation. - Code Style: - I removed unnecessary comments that were explaining header includes. - I removed placeholder comments from public headers. - I updated the copyright year to 2025 in all newly added files. - Android Performance: - I optimized Android's `ListResultInternal` to cache converted items, prefixes, and the page token. This will avoid repeated JNI calls on subsequent accesses. - Cleanup Mechanism: - I simplified the `ListResult` cleanup by removing the `ListResultInternalCommon` class. `ListResult` now directly manages the cleanup registration of its `internal_` member, similar to `StorageReference`. --- .../integration_test/src/integration_test.cc | 107 ++++----- storage/src/android/list_result_android.cc | 77 +++++-- storage/src/android/list_result_android.h | 10 +- storage/src/common/list_result.cc | 213 ++++++++---------- .../src/common/list_result_internal_common.h | 68 ------ .../include/firebase/storage/list_result.h | 2 +- .../firebase/storage/storage_reference.h | 1 - .../src/ios/fir_storage_list_result_pointer.h | 2 +- 8 files changed, 211 insertions(+), 269 deletions(-) delete mode 100644 storage/src/common/list_result_internal_common.h diff --git a/storage/integration_test/src/integration_test.cc b/storage/integration_test/src/integration_test.cc index c306309e96..f61bf47520 100644 --- a/storage/integration_test/src/integration_test.cc +++ b/storage/integration_test/src/integration_test.cc @@ -101,9 +101,6 @@ class FirebaseStorageTest : public FirebaseTest { void TearDown() override;

From 2ceddb263a202c17b05adfee49953346071c382d Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Mon, 9 Jun 2025 23:28:19 +0000 Subject: [PATCH 3/7] refactor: Address review comments for Storage List API Incorporates feedback from the initial review of the List API: - Build Fix: - Explicitly namespaced StorageReference in list_result.h to resolve undeclared identifier error. - Integration Tests: - Removed SKIP_TEST_ON_ANDROID_EMULATOR from ListAllBasic and ListPaginated tests. - Refactored list tests to create their own unique root folders instead of using a shared one in the test fixture, improving test isolation. - Code Style: - Removed unnecessary comments explaining header includes. - Removed placeholder comments from public headers. - Updated copyright year to 2025 in all newly added files. - Ran code formatter (scripts/format_code.py -git_diff) on all changed files. - Android Performance: - Optimized Android's ListResultInternal to cache converted items, prefixes, and page token. This avoids repeated JNI calls on subsequent accesses. - Cleanup Mechanism: - Simplified ListResult cleanup by removing the ListResultInternalCommon class. ListResult now directly manages the cleanup registration of its internal_ member, similar to StorageReference. --- .../integration_test/src/integration_test.cc | 161 ++++++++++-------- storage/src/android/list_result_android.cc | 38 +++-- storage/src/android/list_result_android.h | 7 +- .../src/android/storage_reference_android.cc | 18 +- storage/src/common/list_result.cc | 23 +-- storage/src/common/storage_reference.cc | 4 +- storage/src/desktop/list_result_desktop.cc | 12 +- storage/src/desktop/list_result_desktop.h | 11 +- .../src/desktop/storage_reference_desktop.cc | 16 +- .../src/desktop/storage_reference_desktop.h | 6 +- .../include/firebase/storage/list_result.h | 4 +- 11 files changed, 167 insertions(+), 133 deletions(-) diff --git a/storage/integration_test/src/integration_test.cc b/storage/integration_test/src/integration_test.cc index f61bf47520..8f305993c2 100644 --- a/storage/integration_test/src/integration_test.cc +++ b/storage/integration_test/src/integration_test.cc @@ -20,7 +20,7 @@ #include #include #include // NOLINT -#include // For std::vector in list tests +#include // For std::vector in list tests #include "app_framework.h" // NOLINT #include "firebase/app.h" @@ -84,7 +84,6 @@ using testing::ElementsAreArray;
