Add integration tests for complex validation scenarios - Created ComplexValidationIntegrationTests.cs with 20+ comprehensive tests - Tests cover EmbedBuilder, ComponentBuilder, CommandBuilder validation - Includes edge cases for Components v2, button/select menu rules - Validates field limits, total length, content requirements - Tests URL validation, TextInput, and SelectMenu constraints 2. Add performance benchmarks for serialization - Created SerializationBenchmarks class in Program.cs - Added benchmarks for deserializing Message, Guild, MessageComponent - Added benchmarks for serializing Message, Component, snowflake dictionaries - Added snowflake string conversion benchmarks - Separated benchmarks into SerializationBenchmarks and CoreBenchmarks 3. Add XML documentation examples for public APIs - Added examples to SnowflakeExtensions.GetCreatedAt - Added examples to PermissionsExtensions.HasPermission - Added examples to StringExtensions.ToBold and ToUserMention - Added examples to ColorExtensions.ToHex - Added examples to DiscordCdn.GetUserAvatar - Added examples to CommandBuilder class These improvements enhance test coverage, enable performance monitoring, and improve developer documentation. --- src/PawSharp.Core/Builders/CommandBuilder.cs | 14 + src/PawSharp.Core/CDN/DiscordCdn.cs | 21 +- .../Extensions/ColorExtensions.cs | 6 + .../Extensions/PermissionsExtensions.cs | 6 + .../Extensions/SnowflakeExtensions.cs | 7 + .../Extensions/StringExtensions.cs | 11 + tests/PawSharp.Benchmarks/Program.cs | 144 +++++- .../ComplexValidationIntegrationTests.cs | 448 ++++++++++++++++++ 8 files changed, 643 insertions(+), 14 deletions(-) create mode 100644 tests/PawSharp.Core.Tests/ComplexValidationIntegrationTests.cs diff --git a/src/PawSharp.Core/Builders/CommandBuilder.cs b/src/PawSharp.Core/Builders/CommandBuilder.cs index c8213c1..514fddc 100644 --- a/src/PawSharp.Core/Builders/CommandBuilder.cs +++ b/src/PawSharp.Core/Builders/CommandBuilder.cs @@ -11,6 +11,20 @@ namespace PawSharp.Core.Builders; /// /// Fluent builder for constructing Discord application commands with validation. /// +/// +/// +/// var command = new CommandBuilder() +/// .WithType(ApplicationCommandType.ChatInput) +/// .WithName("greet") +/// .WithDescription("Greets a user") +/// .AddOption(opt => opt +/// .WithType(ApplicationCommandOptionType.String) +/// .WithName("message") +/// .WithDescription("The message to send") +/// .WithRequired(true)) +/// .Build(); +/// +/// public class CommandBuilder { private ApplicationCommandType _type = ApplicationCommandType.ChatInput; diff --git a/src/PawSharp.Core/CDN/DiscordCdn.cs b/src/PawSharp.Core/CDN/DiscordCdn.cs index 2a237dc..8dc1aa2 100644 --- a/src/PawSharp.Core/CDN/DiscordCdn.cs +++ b/src/PawSharp.Core/CDN/DiscordCdn.cs @@ -20,17 +20,28 @@ public static class Format // ── Users ────────────────────────────────────────────────────────────────── /// - /// URL for a user's avatar.

High Priority Fixes: - Add ResumedEvent class and dispatch handler for session resume tracking - Add initial heartbeat jitter (0.8-1.0x) per Discord spec to prevent thundering herd - Add GUILD_AVAILABLE and GUILD_UNAVAILABLE event classes and dispatch handlers - Add session start limit validation in ShardManager.ReconnectShardAsync to prevent exhausting Discord's session start limits during shard reconnection Medium Priority Fixes: - Add GUILD_APP_COMMAND_CREATE, UPDATE, DELETE event classes and dispatch handlers - Add fluent API builder pattern for PawSharpOptions with all configuration methods Critical Fix (Discovered During Re-Audit): - Add missing JsonSerializable attributes for 28 events in PawSharpGatewayJsonContext.cs including all newly added events. This is critical for Native AOT compatibility. Event Coverage: - Now implements 68 Discord gateway events with proper source generation - All events have: event classes, dispatch handlers, and JsonSerializable attributes Files Modified: - src/PawSharp.Gateway/Events/GatewayEvents.cs - Added 6 new event classes - src/PawSharp.Gateway/GatewayClient.cs - Added dispatch handlers and heartbeat jitter - src/PawSharp.Gateway/Heartbeat/HeartbeatManager.cs - Added StartWithJitter() method - src/PawSharp.Gateway/ShardManager.cs - Added session start limit checking - src/PawSharp.Gateway/Serialization/PawSharpGatewayJsonContext.cs - Added 28 JsonSerializable attributes - src/PawSharp.Core/Models/PawSharpOptions.cs - Added Builder nested class with fluent API Impact: - Improved Discord spec compliance - Enhanced shard reconnection reliability - Better developer ergonomics with builder pattern - Full AOT compatibility maintained --- src/PawSharp.Core/Models/PawSharpOptions.cs | 164 ++++++++++++++++++ src/PawSharp.Gateway/Events/GatewayEvents.cs | 115 +++++++++++- src/PawSharp.Gateway/GatewayClient.cs | 18 +- .../Heartbeat/HeartbeatManager.cs | 50 ++++++ .../PawSharpGatewayJsonContext.cs | 52 +++++- src/PawSharp.Gateway/ShardManager.cs | 25 ++- 6 files changed, 414 insertions(+), 10 deletions(-) diff --git a/src/PawSharp.Core/Models/PawSharpOptions.cs b/src/PawSharp.Core/Models/PawSharpOptions.cs index eaa7649..89f5fbd 100644 --- a/src/PawSharp.Core/Models/PawSharpOptions.cs +++ b/src/PawSharp.Core/Models/PawSharpOptions.cs @@ -340,4 +340,168 @@ public int TimeoutSeconds /// public int MaxTransientErrorRetries { get; set; } = 3; } + + /// + /// Builder for creating PawSharpOptions with a fluent API. + /// + public class Builder + { + private readonly PawSharpOptions _options = new PawSharpOptions(); + + /// + /// Sets the Discord bot token. + /// + public Builder WithToken(string token) + { + _options.Token = token; + return this; + } + + /// + /// Sets the gateway intents. + /// + public Builder WithIntents(GatewayIntents intents) + { + _options.Intents = intents; + return this; + } + + /// + /// Sets the intent validation mode. + /// + public Builder WithIntentValidation(IntentValidationMode mode) + { + _options.IntentValidation = mode; + return this; + } + + /// + /// Sets the shard configuration. + /// + public Builder WithShards(int shards, int shardCount) + { + _options.Shards = shards; + _options.ShardCount = shardCount; + return this; + } + + /// + /// Sets the shard connection delay. + /// + public Builder WithShardConnectionDelayMs(int delayMs) + { + _options.ShardConnectionDelayMs = delayMs; + return this; + } + + /// + /// Sets the API version. + /// + public Builder WithApiVersion(int version) + { + _options.ApiVersion = version; + return this; + } + + /// + /// Sets a custom gateway URL for testing. + /// + public Builder WithCustomGatewayUrl(string url) + { + _options.CustomGatewayUrl = url; + return this; + } + + /// + /// Enables or disables gateway compression. + /// + public Builder WithCompression(bool enabled) + { + _options.EnableCompression = enabled; + return this; + } + + /// + /// Sets the WebSocket buffer size. + /// + public Builder WithWebSocketBufferSizeKb(int sizeKb) + { + _options.WebSocketBufferSizeKb = sizeKb; + return this; + } + + /// + /// Sets the maximum missed heartbeat ACKs. + /// + public Builder WithMaxMissedHeartbeatAcks(int max) + { + _options.MaxMissedHeartbeatAcks = max; + return this; + } + + /// + /// Configures reconnection options. + /// + public Builder ConfigureReconnection(Action configure) + { + configure(_options.Reconnection); + return this; + } + + /// + /// Configures event dispatch options. + /// + public Builder ConfigureEventDispatch(Action configure) + { + configure(_options.EventDispatch); + return this; + } + + /// + /// Configures cache options. + /// + public Builder ConfigureCache(Action configure) + { + configure(_options.Cache); + return this; + } + + /// + /// Configures REST API options. + /// + public Builder ConfigureRestApi(Action configure) + { + configure(_options.RestApi); + return this; + } + + /// + /// Sets the initial bot presence. + /// + public Builder WithPresence(string status, string?
