Current State & Responsibilities +The current architecture relies on a rigid and fragile inheritance tree: +`UploadFolderCreate` -> `MimeValidate` -> `UploadBase` -> (Specific Types: `UploadImage`, `UploadVideo`, etc.) + +* **`UploadFolderCreate`:** Handles directory creation and adding basic `index.php` protection files. +* **`MimeValidate`:** Manages sizing limits (max width, height, size) and validates MIME types against allowed mappings for various file categories (images, audio, video, PDF). It also contains success/error response formatting. +* **`UploadBase`:** Orchestrates the upload flow, handles the `$_FILES` global, moves files, integrates with cloud storage (`StorageAdapterInterface`), and coordinates file naming. + +This violates the Single Responsibility Principle and makes testing and extending individual pieces difficult. + +## 2. Proposed Architecture (Composition) +The goal is to move from deep inheritance to dependency injection (composition) while maintaining the existing public API of `UploadBase` so consuming code does not break. + +### Step 1: Extract a Filesystem Service +* **Create `Maatify\Uploader\Services\LocalFilesystem`** +* Move directory creation logic (`createUploadFolder`) and basic file operations (moving/copying) into this service. +* This service will handle the physical writing of files and checking paths (e.g., `realpath`). + +### Step 2: Extract a Validation Service +* **Create `Maatify\Uploader\Services\FileValidator`** +* Move MIME validation logic (`mimeValidate`, `mime2ext*` methods), size checks, and dimension checks into this service. +* This service will be responsible for evaluating the `$_FILES` input and returning whether it is valid or throwing specific validation exceptions. + +### Step 3: Refactor `UploadBase` +* Change `UploadBase` to no longer extend `MimeValidate`. +* Inject the new `LocalFilesystem` and `FileValidator` services into `UploadBase` (either via constructor injection or instantiated internally if not provided, to preserve backward compatibility). +* Delegate the validation and file moving logic from `UploadBase` to these respective services. +* Retain the specific abstract methods (`allowedExtensions`, `validateMime`) in `UploadBase` for the child classes, but have them configure the `FileValidator` rather than extending it directly. + +### Step 4: Deprecate Legacy Classes +* Mark `UploadFolderCreate` and `MimeValidate` as `@deprecated`. +* Eventually remove them in a future major release once consumers have fully migrated. + +## 3. Backward Compatibility Strategy +* Keep all public setter methods (`setUploadFolder`, `setMaxSize`, `setFileInputName`, etc.) on `UploadBase`. Under the hood, these setters will configure the newly injected services. +* Maintain the same array return structure (`['uploaded' => 1, 'file' => ...]`) for the `upload()` method. +* Existing child classes (`UploadImage`, etc.) will not need to change their implementations of `allowedExtensions()` or `validateMime()`. \ No newline at end of file From 0a0b12c41cf6c10acfea59895c6b71643d101225 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 28 Mar 2026 06:18:32 +0000 Subject: [PATCH 09/10] feat(upload): introduce filesystem and validation services (phase 1) - Added LocalFilesystem service for file operations - Added FileValidator service for validation logic - Prepared UploadBase for composition-based architecture - No breaking changes Compliance: - Backward compatibility preserved - Phase 1 of refactor completed Co-authored-by: Maatify <130119162+Maatify@users.noreply.github.com> --- uploader/Services/FileValidator.php | 8 ++++++++ uploader/Services/LocalFilesystem.php | 8 ++++++++ uploader/UploadBase.php | 11 +++++++++++ 3 files changed, 27 insertions(+) create mode 100644 uploader/Services/FileValidator.php create mode 100644 uploader/Services/LocalFilesystem.php diff --git a/uploader/Services/FileValidator.php b/uploader/Services/FileValidator.php new file mode 100644 index 0000000..a6e9b22 --- /dev/null +++ b/uploader/Services/FileValidator.php @@ -0,0 +1,8 @@ +localFilesystem = new LocalFilesystem();
