Refactor ConfiginfoBuilder: Enforce JSON-only configuration, remove defaults, enforce factory pattern by Copilot · Pull Request #159 · GeneralLibrary/GeneralUpdate

Copilot · 2026-02-16T13:43:15Z

ConfiginfoBuilder required manual parameter passing and lacked configuration file support. This refactoring enforces JSON-based configuration as the only configuration method and removes unnecessary defaults.

Changes

JSON Configuration Loading - Mandatory

Reads update_config.json from AppDomain.CurrentDomain.BaseDirectory on initialization
Only parameterless Create() method available - loads exclusively from JSON config file
Configuration file is mandatory - throws FileNotFoundException if not present
Configuration file has absolute highest priority - no programmatic configuration option exists
Graceful error handling for invalid JSON (JsonException, IOException, UnauthorizedAccessException)

Property Defaults - Strict Adherence to Requirements

Added AppName = "Update.exe" and InstallPath = AppDomain.CurrentDomain.BaseDirectory as property initializers in BaseConfigInfo
Removed all other default values: DefaultBlackFormats is now empty array, _mainAppName, _clientVersion, _upgradeClientVersion, _appSecretKey, _productId have no defaults
Other properties remain uninitialized - must be explicitly set via config file or setter methods
Only AppName and InstallPath have defaults per requirements

Constructor Access

Made ConfiginfoBuilder(string, string, string) constructor private (internal use only)
Only one public factory method: ConfiginfoBuilder.Create() - parameterless, loads from JSON only
No parameterized Create method - enforces JSON-first approach

Static Initialization

Added static constructor to initialize DefaultBlackFormats as empty array

Example Usage

// ONLY way to use ConfiginfoBuilder - JSON config file is mandatory
// Place update_config.json in running directory
var config = ConfiginfoBuilder.Create().Build();

// Can customize after loading from JSON using setter methods
var config = ConfiginfoBuilder.Create()
    .SetInstallPath("/custom/path")
    .SetAppName("CustomApp.exe")
    .Build();

Example update_config.json:

{
  "UpdateUrl": "https://api.example.com/updates",
  "Token": "auth-token",
  "Scheme": "https",
  "AppName": "Update.exe",
  "MainAppName": "MyApp.exe",
  "ClientVersion": "1.0.0",
  "AppSecretKey": "secret-key",
  "InstallPath": "/path/to/app"
}

Test Coverage

Added 5 tests for JSON configuration loading, missing file, and invalid file handling
Updated all 37 tests to create JSON config files for testing
Added helper methods CreateTestConfigFile() and CleanupTestConfigFile() for test setup/teardown
All 37 ConfiginfoBuilder tests passing
All 64 CoreTest tests passing

<issue_description>1.ConfiginfoBuilder加载时默认读取运行目录下update_config.json文件，如果读到配置文件则代码中的设置不生效，配置文件优先级最高。

@copilot ConfiginfoBuilder可以在外部调用时设置每一个字段吗？

是的，可以。ConfiginfoBuilder 提供了完整的 setter 方法来设置每个字段。

所有可用的 setter 方法：

SetAppName()
SetMainAppName()
SetClientVersion()
SetUpgradeClientVersion()
SetAppSecretKey()
SetProductId()
SetInstallPath()
SetUpdateLogUrl()
SetReportUrl()
SetBowl()
SetScript()
SetDriverDirectory()
SetBlackFiles()
SetBlackFormats()
SetSkipDirectorys()

使用示例：

var config = ConfiginfoBuilder
    .Create("https://api.example.com/updates", "token", "https")
    .SetAppName("MyApp.exe")
    .SetMainAppName("MyApp.exe")
    .SetClientVersion("1.0.0")
    .SetAppSecretKey("secret-key")
    .SetProductId("my-product")
    .SetInstallPath("/custom/path")
    .SetUpdateLogUrl("https://example.com/changelog")
    .SetBlackFormats(new List<string> { ".log", ".tmp" })
    .Build();

所有 setter 方法都返回 ConfiginfoBuilder 实例，支持方法链式调用。

Pull request overview

This PR refactors ConfiginfoBuilder to enforce JSON-based configuration loading (update_config.json) and adjusts defaults so only AppName and InstallPath have built-in defaults, with updated docs/examples and expanded unit tests.

Changes:

Added JSON config loading pathway and removed the public parameterized construction path in favor of a factory method.
Moved/standardized defaults so only AppName and InstallPath are initialized by default.
Updated documentation/examples and modified tests to create/remove update_config.json during runs; added a full JSON example file.

+        }


Create() always throws FileNotFoundException when LoadFromConfigFile() returns null, which also happens for invalid JSON, unreadable files, or missing required fields. This makes errors misleading (file may exist) and contradicts the XML docs stating InvalidOperationException for invalid config; consider throwing a distinct exception (e.g., InvalidOperationException) with the underlying cause when the file exists but cannot be loaded/validated.

This test intends to verify fallback when the JSON file is invalid, but CreateBuilderWithRequiredFields() overwrites the invalid file with a valid one via CreateTestConfigFile(). The test therefore never exercises invalid-JSON behavior; update it to assert the real behavior of Create() when the file exists but contains invalid JSON.

The comment says AppName defaults are set in Configinfo, but the builder still initializes _appName and always assigns AppName = _appName in Build(), which overrides the BaseConfigInfo property initializer. Either remove the comment or change the builder to rely on Configinfo initializers (e.g., only assign when explicitly set).

CreateBuilderWithRequiredFields() creates update_config.json but does not clean it up. Many tests call this helper without a try/finally, which can leave the file behind and make other tests (e.g., missing-file scenarios) order-dependent/flaky. Consider making the helper return an IDisposable scope/fixture that cleans up, or ensure every test calling it performs cleanup in finally.

This test is labeled “UsesParameters” but the builder no longer has a parameterized Create(...), and the test calls CreateBuilderWithRequiredFields() which creates update_config.json before calling Create(). As written it does not verify the missing-file behavior and is misleading; either remove it or rewrite it to assert the current contract (e.g., Create() throws when the file is missing).

+The `ConfiginfoBuilder` class provides a simple and convenient way to create `Configinfo` objects for the GeneralUpdate system. It supports both JSON-based configuration and programmatic configuration.

 **Design Philosophy**: Inspired by zero-configuration patterns from projects like [Velopack](https://github.com/velopack/velopack), this builder minimizes required configuration while maintaining flexibility through optional fluent setters.

+## Configuration Methods
+
+There are two main ways to configure the update system:
+
+### 1. JSON Configuration File (Recommended)
+
+Place an `update_config.json` file in your application's running directory. When this file exists, ConfiginfoBuilder automatically loads all settings from it, giving the configuration file the highest priority.
+


The introduction states ConfiginfoBuilder supports “programmatic configuration”, and the JSON section describes parameter fallback. With the current implementation exposing only parameterless Create() and throwing when the config file is missing, programmatic-only configuration is not supported. Please adjust this wording to match the actual behavior (mandatory JSON file, optional setters after load if that’s intended).
