Improves the current-run cleanup mechanism by tracking file downloads explicitly. This ensures that files downloaded via BITS or preserving older timestamps are correctly identified and removed during cleanup. Extends the run manifest schema to support file backups, allowing for safe restoration of pre-existing scripts and configuration files modified during a run. Additional cleanup logic now correctly prunes residual empty directories after tracked files are removed.
Extracts duplicate folder removal code across multiple driver modules (Dell, HP, Lenovo, Microsoft) into a centralized `Remove-DriverModelFolder` helper function. This new utility includes safety checks to prevent accidental deletion of the drivers root directory or paths outside the drivers folder hierarchy.
Also moves model path construction in the Microsoft driver module earlier in the function to ensure consistent path handling before any operations that might fail.
Benefits improved maintainability, reduces code duplication, and adds protective safeguards for destructive operations during error handling.
Updates compression workflow to use consistent status messaging and better error handling across all driver vendor modules (Dell, HP, Lenovo, Microsoft).
Changes improve status tracking by:
- Standardizing compression success status to "Compression successful" instead of vendor-specific messages
- Introducing relative path variables to reduce code duplication and improve maintainability
- Suppressing command output by piping to `$null` for cleaner execution
- Adding explicit failure state in exception handlers to ensure success property reflects actual outcome
- Updating parallel processing logic to recognize the new standardized compression status
These modifications ensure consistent behavior across vendors and make the parallel processing coordinator aware of all compression completion states.
- Implements detailed failure tracking for driver downloads, capturing model names and statuses for failed attempts.
- Updates logging to provide clearer messages for both successful and failed downloads, improving traceability.
- Modifies the user interface to display comprehensive error messages when downloads fail, including a summary of failed models.
- Ensures that all exceptions during download and extraction processes are logged and thrown, preventing silent failures.
- Client OSes will now use CatalogIndexPC.xml to identify which ProductLine_SystemID.xml to use to identify which drivers to download. This is inline with how DCU works.
- In the UI, Dell Model names now show the full product line, model number, and system ID in the model column.
- There are many more models now shown due to breaking each model out by systemID (one model will have many systemIDs).
- Downloads per model should be much smaller as prior code was downloading drivers for models that Dell had reused their model number (e.g. Precision/Inspiron/Latitude/Vostro 3520 would result in a very large driver download)
- Dell driver downloads are best effort based on the data from the XML files. In some cases the Dell support website may show a newer driver than what is downloaded. This is rare, but in testing I've seen one or two drivers per model where the XML doesn't have what's listed on Dell's website. Again, rare, but not unexpected.
Introduces a new common function, `ConvertTo-SafeName`, to sanitize strings by removing characters that are invalid in Windows file paths.
This function is now used consistently when creating directory and file names for drivers (Dell, HP, Lenovo, Microsoft) and applications to prevent path-related errors. It replaces several ad-hoc sanitization methods with a single, more robust implementation.
Implements a deferred cleanup mechanism for driver source folders when they are compressed to a WIM and also used for WinPE.
When drivers are compressed, the original source folders are now preserved if they are also needed for WinPE driver injection. A marker file is created in these preserved folders.
A new cleanup step is added after the WinPE media creation to remove these preserved folders, ensuring they are available when needed but not left behind permanently.
Adds standard PowerShell comment-based help blocks (synopsis and description) to all UI and common library script modules (`.psm1`) and the main UI entry point script (`.ps1`).
This improves maintainability and discoverability by documenting the purpose of each script file. Also removes various redundant or commented-out code blocks.
Removes the logic that adds a `Success` property to the returned object when an existing driver package is found.
This property is handled by the calling function, making this assignment unnecessary and simplifying the driver-saving task functions.
Implements logic to compress previously downloaded driver folders into WIM files if the compression option is enabled. This ensures consistency in the driver store when re-running the download process.
Refactors the parallel task processing to rely on a standardized boolean 'Success' property from all driver download tasks. This simplifies the result handling logic and makes it more reliable than parsing status strings.
Adds a new `Test-ExistingDriver` function to the common driver module to centralize the logic for checking if drivers have already been downloaded, either as a folder or a WIM file.
This change removes duplicated code from the Dell, HP, Lenovo, and Microsoft driver download tasks, simplifying maintenance and ensuring consistent behavior across all manufacturers.
Refactors the driver download logic for all manufacturers to first check for the existence of a final `.wim` archive. If a WIM file is found, the download and processing for that model is skipped, significantly improving performance on subsequent runs.
This change also resolves a potential type conversion error when processing driver mapping JSON files and corrects a minor typo in a log message.
Adds a `DriverMapping.json` file to automate driver injection during image deployment.
Driver download tasks now generate or update this mapping file with the relative path for each successfully downloaded driver package.
The deployment script now uses this file to automatically detect and select the correct drivers for the target hardware, removing the need for manual selection. The manual driver selection prompt is retained as a fallback.
Refactors the Dell driver catalog parsing to use a streaming `System.Xml.XmlReader` instead of loading the entire XML file into memory.
This change significantly reduces the memory footprint and improves performance, especially when processing large catalog files. The new approach reads the file node by node, processing each software component individually.
Moves the Dell catalog download and preparation logic from the individual driver download task to the parent function.
This prevents a race condition where multiple parallel tasks would attempt to download and extract the same catalog file simultaneously. The catalog is now prepared once before any driver downloads begin, improving efficiency and reliability.
Additionally, comments out manual garbage collection calls in the VM build UI.
Moves the logic for downloading and preparing the Dell driver catalog from the main build scripts directly into the specific Dell driver download task.
This change encapsulates all Dell-specific logic within the `Save-DellDriversTask` function, making it self-sufficient. Each parallel task now manages its own dependency on the catalog file, which simplifies the main script's responsibilities.
Also includes minor code style formatting.
Relocates driver-specific download, parsing, and management logic from the main UI script and the FFUUI.Core module into new, dedicated modules for each manufacturer (Dell, HP, Lenovo, Microsoft). This improves modularity and code organization.
Additionally, centralizes common HTTP headers and user agent strings in the FFUUI.Core module, accessible via a new helper function.
