Greptile Summary
This release bundles several independent fixes and one performance feature: a CoalescingBuffer that batches per-token Redis publishes into 50 ms / 128-char windows, three execute_activity_method → execute_activity corrections so headers are always injected, a BaseHTTPMiddleware → pure ASGI swap that fixes streaming response buffering, and an AGENTEX_CUSTOM_HEADERS env-var feature.
- The expanded header-injection scope in
context_interceptor.pynow fireslogger.warningfor every non-agentex activity that lacks_task_id, which will flood logs in multi-activity workflows. send_message(sync + async) silently discards JSON-RPC error payloads when the server returns an error envelope, returning an emptyresultlist instead.
Confidence Score: 4/5
Safe to merge with minor follow-up; no data loss or critical runtime failures introduced.
Both findings are P2: the warning log noise in the interceptor is annoying but not functionally breaking, and the silent error discard in send_message was a pre-existing gap now made slightly more likely to hit. All P0/P1 bugs (execute_activity fix, BaseHTTPMiddleware streaming fix, multipart field naming) are addressed with tests.
src/agentex/resources/agents.py (silent error swallowing in send_message) and src/agentex/lib/core/temporal/plugins/openai_agents/interceptors/context_interceptor.py (warning log level).
Important Files Changed
| Filename | Overview |
|---|---|
| src/agentex/lib/core/services/adk/streaming.py | Major addition: CoalescingBuffer (50ms/128-char windowed batching), StreamingMode literal, and delta merge helpers; StreamingTaskMessageContext updated to dispatch through the new buffer. |
| src/agentex/resources/agents.py | send_message (sync + async) refactored to consume a streaming response and reconstruct the final result; JSON-RPC error chunks are silently discarded with an empty task_messages list. |
| src/agentex/lib/core/temporal/plugins/openai_agents/interceptors/context_interceptor.py | Header injection scope widened from model-only activities to all activities; logger.warning fires for every non-agentex workflow activity that lacks _task_id/_trace_id/_parent_span_id. |
| src/agentex/lib/sdk/fastacp/base/base_acp_server.py | RequestIDMiddleware replaced from BaseHTTPMiddleware (which buffers streaming responses) to a pure ASGI middleware; fixes streaming response truncation. |
| src/agentex/_utils/_utils.py | extract_files now accepts an array_format parameter and delegates suffix generation to _array_suffix; fixes bracket/indices/repeat/comma naming for multipart file arrays. |
| src/agentex/_client.py | Added AGENTEX_CUSTOM_HEADERS env var support (newline-delimited key:value pairs) in both sync and async clients; env headers take precedence over default_headers argument. |
| src/agentex/lib/core/temporal/plugins/openai_agents/hooks/hooks.py | Switched execute_activity_method to execute_activity for stream_lifecycle_content calls; ensures header injection by the context interceptor. |
| pyproject.toml | Bumped httpx (0.27 → 0.28), litellm minimum (1.83.0 → 1.83.7 for security patch), pinned starlette>=0.49.1 and tornado>=6.5.5 explicitly, and relaxed fastapi upper bound. |
