From 9124d51e0eda5f3bc790a6c5f8fc5c7605c62f02 Mon Sep 17 00:00:00 2001 From: Victor Dibia Date: Mon, 2 Mar 2026 02:34:25 -0800 Subject: [PATCH 01/10] Python: .NET: Fix .NET conversation memory in DevUI (#3484) (#4294) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Fix .NET conversation memory in DevUI (#3484) * formatting fixes * fix memory regression in python devui , fix for #4123 * Fix for #3983: Added _get_event_type() helper that safely accesses event type on both objects (.type) and dicts (.get("type")). Replaced all 4 bare event.type accesses in _executor.py (lines 267, 477, 499, 523). Root cause: PR #3690 changed event.__class__.__name__ == "RequestInfoEvent" (safe) to event.type == "request_info" (crashes on dicts), but _execute_workflow still yields raw dicts on error paths. Test: test_workflow_error_yields_dict_event_without_crash — mocks a workflow that raises, verifies execute_entity consumes the dict error events without crashing. * format fixes * lint fixes --- .../Responses/AIAgentResponseExecutor.cs | 8 +- .../Converters/ItemResourceConversions.cs | 113 ++++++++++++++++++ .../Responses/HostedAgentResponseExecutor.cs | 6 + .../Responses/IResponseExecutor.cs | 3 + .../Responses/InMemoryResponsesService.cs | 19 ++- .../OpenAIResponsesIntegrationTests.cs | 92 ++++++++++++++ .../TestHelpers.cs | 80 +++++++++++++ .../devui/agent_framework_devui/_executor.py | 38 +++--- .../devui/tests/devui/test_execution.py | 45 +++++++ 9 files changed, 388 insertions(+), 16 deletions(-) create mode 100644 dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/Converters/ItemResourceConversions.cs diff --git a/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/AIAgentResponseExecutor.cs b/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/AIAgentResponseExecutor.cs index e3706bee1c..e2e07d00b7 100644 --- a/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/AIAgentResponseExecutor.cs +++ b/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/AIAgentResponseExecutor.cs @@ -31,6 +31,7 @@ internal sealed class AIAgentResponseExecutor : IResponseExecutor public async IAsyncEnumerable ExecuteAsync( AgentInvocationContext context, CreateResponse request, + IReadOnlyList? conversationHistory = null, [EnumeratorCancellation] CancellationToken cancellationToken = default) { // Create options with properties from the request @@ -51,9 +52,14 @@ internal sealed class AIAgentResponseExecutor : IResponseExecutor }; var options = new ChatClientAgentRunOptions(chatOptions); - // Convert input to chat messages + // Convert input to chat messages, prepending conversation history if available var messages = new List(); + if (conversationHistory is not null) + { + messages.AddRange(conversationHistory); + } + foreach (var inputMessage in request.Input.GetInputMessages()) { messages.Add(inputMessage.ToChatMessage()); diff --git a/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/Converters/ItemResourceConversions.cs b/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/Converters/ItemResourceConversions.cs new file mode 100644 index 0000000000..b9a935d54d --- /dev/null +++ b/dotnet/src/Microsoft.Agents.AI.Hosting.OpenAI/Responses/Converters/ItemResourceConversions.cs @@ -0,0 +1,113 @@ +// Copyright (c) Microsoft.

Fixes #1406 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * Use recognizable sanitized IDs for Mermaid node identifiers\n\nReplace generic node_0/node_1 aliases with IDs derived from the original\nexecutor names. ASCII letters, digits, and underscores are preserved;\nother characters become underscores (collapsed, trimmed). Leading digits\nget an n_ prefix. Collisions are resolved with a numeric suffix.\n\nThis keeps node IDs readable in the Mermaid source while the display\nlabels continue to show the full original names." * Remove issue number references from test names and comments" * Address PR review feedback from Copilot\n\n- Add Throw.IfNull(id) guard to SanitizeMermaidNodeId\n- Add safety limit (10,000) to collision resolution loop\n- Restore missing edge assertions (middle1/middle2 --> end)\n- Fix comment to show actual sanitized ID (n_1_User_input)\n- Use stricter regex in Unicode test (must start with letter/underscore)" * Address second round of PR review feedback\n\n- Escape node display labels via EscapeMermaidLabel to handle quotes,\n brackets, and newlines in executor IDs\n- Fix XML doc on SanitizeMermaidNodeId to accurately describe that\n existing consecutive underscores in input are preserved\n- Restore specific edge assertion (mid --> end) in conditional edge test\n- Restore fan-in routing assertions (s1/s2 through intermediate node,\n no direct edges to t) in fan-in test" --------- Co-authored-by: alliscode Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../Visualization/WorkflowVisualizer.cs | 96 ++++++++++-- .../WorkflowVisualizerTests.cs | 146 +++++++++++++++--- 2 files changed, 215 insertions(+), 27 deletions(-) diff --git a/dotnet/src/Microsoft.Agents.AI.Workflows/Visualization/WorkflowVisualizer.cs b/dotnet/src/Microsoft.Agents.AI.Workflows/Visualization/WorkflowVisualizer.cs index e1b69e9f9e..d09273fbc1 100644 --- a/dotnet/src/Microsoft.Agents.AI.Workflows/Visualization/WorkflowVisualizer.cs +++ b/dotnet/src/Microsoft.Agents.AI.Workflows/Visualization/WorkflowVisualizer.cs @@ -153,18 +153,52 @@ public static class WorkflowVisualizer private static void EmitWorkflowMermaid(Workflow workflow, List lines, string indent, string? ns = null) { - string MapId(string id) => ns != null ? $"{ns}/{id}" : id; + // Build a mapping from raw IDs to Mermaid-safe node aliases that preserve + // as much of the original ID as possible for readability. + // Mermaid node IDs cannot contain spaces, dots, pipes, or most special characters. + var aliasMap = new Dictionary(); + var usedAliases = new HashSet(StringComparer.Ordinal); + + string GetSafeId(string id) + { + var key = ns != null ? $"{ns}/{id}" : id; + if (!aliasMap.TryGetValue(key, out var alias)) + { + alias = SanitizeMermaidNodeId(key); + + // Handle collisions by appending a numeric suffix + if (!usedAliases.Add(alias)) + { + var i = 2; + while (!usedAliases.Add($"{alias}_{i}")) + { + if (i >= 10_000) + { + throw new InvalidOperationException($"Unable to generate a unique Mermaid node ID for '{key}'."); + } + + i++; + } + + alias = $"{alias}_{i}"; + } + + aliasMap[key] = alias; + } + + return alias; + } // Add start node var startExecutorId = workflow.StartExecutorId; - lines.Add($"{indent}{MapId(startExecutorId)}[\"{startExecutorId} (Start)\"];"); + lines.Add($"{indent}{GetSafeId(startExecutorId)}[\"{EscapeMermaidLabel(startExecutorId)} (Start)\"];"); // Add other executor nodes foreach (var executorId in workflow.ExecutorBindings.Keys) { if (executorId != startExecutorId) { - lines.Add($"{indent}{MapId(executorId)}[\"{executorId}\"];"); + lines.Add($"{indent}{GetSafeId(executorId)}[\"{EscapeMermaidLabel(executorId)}\"];"); } } @@ -175,7 +209,7 @@ public static class WorkflowVisualizer lines.Add(""); foreach (var (nodeId, _, _) in fanInDescriptors) { - lines.Add($"{indent}{MapId(nodeId)}((fan-in))"); + lines.Add($"{indent}{GetSafeId(nodeId)}((fan-in))"); } } @@ -184,9 +218,9 @@ public static class WorkflowVisualizer { foreach (var src in sources) { - lines.Add($"{indent}{MapId(src)} --> {MapId(nodeId)};"); + lines.Add($"{indent}{GetSafeId(src)} --> {GetSafeId(nodeId)};"); } - lines.Add($"{indent}{MapId(nodeId)} --> {MapId(target)};"); + lines.Add($"{indent}{GetSafeId(nodeId)} --> {GetSafeId(target)};"); } // Emit normal edges @@ -197,17 +231,17 @@ public static class WorkflowVisualizer string effectiveLabel = label != null ?
