@copilot In the newly added ExtensionService.cs file, the download section needs to integrate with ExtensionDownloadService.cs. If ExtensionDownloadService.cs is no longer required, please remove it; otherwise, redundant download functionality will appear. Please fully understand the code before performing the integration. |
… download functionality Co-authored-by: JusterZhu <11714536+JusterZhu@users.noreply.github.com>
I've integrated ExtensionService.Download() with the existing ExtensionDownloadService infrastructure. The key changes:
ExtensionDownloadService remains as the core download service and is properly utilized without redundancy. All 235 tests pass. Changes in commit 945d539 |

@copilot Your understanding is incorrect. The download functionality is already implemented in ExtensionDownloadService.cs, and the newly added ExtensionService.cs also contains download functionality—their capabilities overlap at a macro level, and two separate sets of download capabilities are unnecessary in the current scenario. Therefore, you need to merge them and retain only one implementation. |

There are an excessive number of parameters in the constructor of GeneralExtensionHost, which need to be encapsulated into an object and passed in. |

Pull request overview
This pull request refactors the Extension module by introducing a unified ExtensionService that consolidates both query and download functionality, adds HTTP authentication support throughout the download pipeline, and implements a configuration object pattern for cleaner API design.
Changes:
- Unified extension operations into a single
ExtensionServicethat handles querying, downloading, and dependency resolution, replacing the separateExtensionDownloadService - Added HTTP authentication support with
AuthSchemeandAuthTokenproperties flowing throughExtensionHostConfig→ExtensionService→VersionInfo→DownloadTask - Introduced
ExtensionHostConfigclass to encapsulate constructor parameters, with the old constructor marked as obsolete for backward compatibility

The obsolete constructor forwards to the new config-based constructor, but the body is empty. While this is technically correct, it would be clearer to add a comment explaining that all initialization is handled by the config-based constructor through constructor chaining. For example:
{
// All initialization is handled by the config-based constructor through constructor chaining
}
This improves code readability and prevents confusion about why the constructor body is empty.

Dependencies are collected but only the main extension is downloaded. The comment acknowledges this limitation, but it creates an incomplete implementation. Users calling this method expecting dependencies to be downloaded will encounter failures when they try to use the extension.
Consider either:
- Implementing full dependency download and returning a collection of files
- Documenting clearly in the method's XML comments that dependencies are NOT downloaded
- Returning dependency information in the response so callers know what else needs to be downloaded
The current implementation collects dependencies (lines 243-255) but doesn't use them, which is misleading.

The variable 'extensionsToDownload' is created and dependencies are added to it (lines 240-255), but this collection is never used afterward. Only the main extension is downloaded (line 262). This is dead code that should be removed or the functionality should be completed.
Either remove the unused collection and dependency resolution code, or implement the full dependency download functionality.

When an exception occurs during download, the MemoryStream created at line 274 may not be disposed if the exception happens after that point but before the return. While currently the stream creation is the last operation before return, future modifications could introduce this leak.
Consider wrapping the stream creation in a try-catch or using a pattern that ensures proper cleanup on exceptions.
| // Read the file into a memory stream | ||
| var fileBytes = File.ReadAllBytes(downloadedPath); | ||
| var stream = new MemoryStream(fileBytes); |

The MemoryStream created here is not disposed, and the responsibility for disposal is placed on the caller. This creates a potential memory leak if callers forget to dispose the stream. Consider one of these alternatives:
- Make DownloadExtensionDTO implement IDisposable and dispose the stream in its Dispose method
- Return FileStream directly instead of copying to MemoryStream, allowing the caller to use it with 'using' statements
- Document clearly in the method's XML comments that callers MUST dispose the stream
While the XML comment on the method and DTO mention disposal responsibility, the risk of memory leaks remains high. The current implementation reads the entire file into memory unnecessarily.
| // Read the file into a memory stream | |
| var fileBytes = File.ReadAllBytes(downloadedPath); | |
| var stream = new MemoryStream(fileBytes); | |
| // Open a read-only stream for the downloaded file | |
| var stream = File.OpenRead(downloadedPath); |

The validation method does not check if DownloadTimeout is valid (e.g., greater than 0). Negative or zero timeout values could cause issues in the download operations. Consider adding validation such as:
if (DownloadTimeout <= 0)
throw new ArgumentOutOfRangeException(nameof(DownloadTimeout), "Download timeout must be greater than 0");
This would prevent invalid configuration from being used and provide clear error messages to users.

The validation only checks if both AuthScheme and AuthToken are non-empty, but doesn't validate the mutual dependency. If only one is provided, authentication will silently fail. Consider adding validation to ensure either both are provided or neither:
if (!string.IsNullOrEmpty(AuthScheme) ^ !string.IsNullOrEmpty(AuthToken))
throw new ArgumentException("Both AuthScheme and AuthToken must be provided together, or neither should be set");
This would prevent misconfiguration where only one authentication parameter is set.
| throw new ArgumentNullException(nameof(DownloadPath)); | |
| throw new ArgumentNullException(nameof(DownloadPath)); | |
| // Ensure authentication configuration is consistent: either both are set or both are unset. | |
| if (!string.IsNullOrEmpty(AuthScheme) ^ !string.IsNullOrEmpty(AuthToken)) | |
| { | |
| throw new ArgumentException( | |
| "Both AuthScheme and AuthToken must be provided together, or neither should be set"); | |
| } |

ExtensionHostConfigclass to encapsulate all constructor parametersGeneralExtensionHost(ExtensionHostConfig config)[Obsolete]but still functional for backward compatibilityHTTP Authentication Support:
