Some exception classes (e.g. anyio.ClosedResourceError) are raised without
a message argument, so str(exc) returns an empty string. The existing error
format f'{type(exc).__name__}: {exc}' would produce messages like
'MCP call failed: ClosedResourceError: ' with nothing after the colon.
Add _exc_str() helper that falls back to repr(exc) when str(exc) is empty,
and apply it to all 6 MCP error formatting sites (5 tool/prompt/resource
handlers + 1 sampling handler).
Fixes#19417
Treat closed-resource, closed-transport, broken-pipe, and EOF MCP failures as stale session equivalents so the existing reconnect/retry-once path can recover. Add regression coverage for the stale-pipe marker variants.\n\nChecks:\n- python -m py_compile tools/mcp_tool.py tests/tools/test_mcp_tool_session_expired.py\n- python -m pytest tests/tools/test_mcp_tool_session_expired.py -q -o addopts=\n- selected secret scan over touched files
The alibaba-coding-plan provider (DashScope coding-intl endpoint) was
defined in providers.py but missing from _PROVIDER_MODELS in models.py.
This caused /model to show "0 models" for this provider even though
credentials were configured and the provider was functional.
Add the curated model list so the provider picker displays available
models correctly.
Extracts the three try/write_runtime_status/except-log blocks into a
shared _write_runtime_status_safe() helper. On failure, logs the first
occurrence per (platform, context) at warning level and downgrades
subsequent failures to debug — so a persistently broken status dir
(permissions, ENOSPC) doesn't spam the log on every Telegram reconnect.
Uses getattr for the _status_write_logged set so test harnesses that
skip __init__ (object.__new__(Adapter)) don't break.
Follow-up to the salvaged #21158.
Track elapsed wall time in _run_on_mcp_loop, cancel the in-flight future when a timeout expires, and raise a descriptive TimeoutError that includes the elapsed and configured timeout. Add regression coverage for the new timeout diagnostics.
Fixes#9930
When an agent session is interrupted (Ctrl+C or gateway timeout), the
current thread's interrupt flag is set in _interrupted_threads. asyncio
executor threads are pooled and reused across sessions, so a thread that
carried an interrupt flag from a prior session will immediately cancel
any new asyncio work dispatched to it — including MCP server discovery.
Fix: in register_mcp_servers(), temporarily clear the interrupt flag on
the current thread before running _discover_all(), then restore it
afterward in a finally block so the original interrupt state is not lost.
Image generation plugins were dispatched without a model name, leaving
the plugin to pick its default. Users on OpenRouter, ComfyUI, or custom
backends had no way to select a specific model through config — they
had to fork the plugin or patch the tool.
Add _read_configured_image_model() that reads image_gen.model from the
active profile's config.yaml and forwards it into
_dispatch_to_plugin_provider(). When model is set, the plugin call
gains a 'model' kwarg; when unset, the plugin falls back to its own
default, so single-model users see no behavior change.
Example config:
image_gen:
provider: openrouter
model: flux-pro
Tests: all 170 image tool tests pass. The new code path is opt-in via
config and no existing test exercises it, so the change is strictly
additive.
## Summary
- Forwards chat-completions `timeout` into the Codex Responses stream call.
- Adds total elapsed-time enforcement while the Responses stream is still yielding events.
- Closes the underlying client on timeout to unblock stalled streams, then raises `TimeoutError`.
- Adds focused tests for timeout forwarding and total timeout enforcement.
## Why
The Codex auxiliary adapter can be used by non-interactive auxiliary work such as context compression. If the stream keeps yielding progress-like events but never completes, SDK socket/read timeouts do not necessarily protect the full operation. This makes the CLI look stuck until the user force-interrupts the whole session.
This is a refreshed upstream-ready version of the earlier fork fix around `d3f08e9a0` / PR #3.
## Verification
- `python -m py_compile agent/auxiliary_client.py tests/agent/test_auxiliary_client.py`
- `python -m pytest -o addopts='' tests/agent/test_auxiliary_client.py::TestCodexAuxiliaryAdapterTimeout -q`
- `git diff --check`
Z.AI (智谱 GLM) vision models (glm-4v-flash, glm-4v-plus, etc.) have two
compatibility issues when used through the Anthropic-compatible endpoint:
1. **Error 1210 — max_tokens rejected on multimodal calls**: Z.AI rejects
the max_tokens parameter for vision model requests with error code 1210
("API 调用参数有误"). The error string does not contain "max_tokens",
so the existing unsupported-parameter retry logic never fires.
2. **Wrong endpoint inheritance**: When the main runtime provider uses Z.AI's
Anthropic-compatible endpoint (open.bigmodel.cn/api/anthropic), the vision
client inherits this endpoint. But Z.AI's Anthropic wire cannot properly
handle image content — models silently fail ("I can't see the image") or
reject max_tokens.
Changes:
- resolve_vision_provider_client(): force Z.AI vision to use OpenAI-compatible
endpoint (open.bigmodel.cn/api/paas/v4) instead of inheriting Anthropic wire
- _build_call_kwargs(): skip max_tokens for Z.AI vision models (4v/5v/-v suffix)
- _AnthropicCompletionsAdapter: support _skip_zai_max_tokens flag
- _to_openai_base_url(): rewrite Z.AI Anthropic URLs to OpenAI-compatible path
- call_llm() retry: detect Z.AI error 1210 and strip max_tokens before retry
The textarea conversion in the previous commit dropped Enter-to-submit
entirely, requiring a mouse click on Create for every single-line task.
Restore the common-case shortcut while preserving multiline entry:
- Enter (no modifier) submits the form
- Shift+Enter inserts a newline
- Escape still cancels
Matches the convention used by Slack, Discord, GitHub PR comment boxes.
- Changed Input component to native textarea for task creation
- Removed Enter-to-submit behavior (use Create button instead)
- Added proper styling: border, padding, rounded corners, focus ring
- 2-row default height with vertical resize and max-height cap
- Escape still cancels the form
- Add hermes dashboard examples to the CLI help epilogue so users can
discover the web UI command from 'hermes --help' output
- Add an independent 'Test dashboard subcommand' CI step that verifies
'hermes dashboard --help' works in the Docker image, with its own
mkdir/chown setup to remain independent of the prior smoke test step
- Prevents regressions like #9153 where the dashboard subcommand was
present in source but missing from the published Docker image
Closes#9153
Two fixes for the local terminal backend on Windows (Git Bash):
1. `_drain()` in base.py: `select.select()` only works on sockets on
Windows, not pipe file descriptors. On Windows, use blocking
`os.read()` in the daemon thread instead. EOF arrives promptly
when bash exits, so this is safe.
2. `_run_bash()` in local.py: When `self.cwd` is updated from `pwd`
output, it contains Git Bash-style paths (`/c/Users/...`).
`subprocess.Popen(cwd=...)` needs a native Windows path
(`C:\Users\...`). Added a conversion before Popen.
Without these fixes, all terminal() calls on Windows return empty
output (exit code 126), and cwd tracking breaks.
Tested on Windows 11 with Git for Windows + Python 3.13.
Fixes#14638
Discord (and similar platforms) can serve a PNG image cached as
discord_xxx.webp because the CDN reports content_type=image/webp for
proxied stickers, custom emoji, and certain bot-uploaded images even
when the actual bytes are PNG. Hermes' agent.image_routing._guess_mime
trusted the file suffix and declared media_type=image/webp to
Anthropic, which strict-validates and returns:
HTTP 400 messages.N.content.M.image.source.base64:
The image was specified using the image/webp media type,
but the image appears to be a image/png image
The Discord image attachment never reaches the model; the whole turn
fails with no salvage path.
Fix: sniff magic bytes in _file_to_data_url before declaring MIME.
Suffix-based detection is kept as a fallback when bytes aren't
available. New helper _sniff_mime_from_bytes covers PNG, JPEG, GIF,
WEBP, BMP, and HEIC/HEIF.
Tests:
- Two existing tests asserted the old broken behaviour (PNG bytes in
a .jpg/.webp file should report jpeg/webp); rewritten with real
jpeg/webp magic bytes so they still cover suffix-aligned cases.
- New regression test test_mime_sniff_overrides_misleading_extension
reproduces the exact Discord scenario (PNG bytes, .webp suffix) and
asserts the data URL comes back as image/png.
All 28 tests in tests/agent/test_image_routing.py pass.
When the provider rejects a request (e.g. invalid model slug like
'--provider nous --model kimi-k2.6' where the valid slug is
'moonshotai/kimi-k2.6'), run_conversation() returns
{failed: True, error: <detail>, final_response: None}. The TUI gateway
and one-shot CLI mode both dropped the error on the floor and emitted
an empty turn, so the user saw a blank response with no indication
that anything went wrong.
Mirror the interactive CLI's existing pattern (cli.py:9832): when
final_response is empty AND (failed|partial) is set AND error is
populated, surface 'Error: <detail>' as the visible text. Leaves
the None-with-no-error path and the '(empty)' sentinel path
untouched — an empty successful turn still renders empty, and
existing sentinel handlers keep owning their lane.
Reported by @counterposition in PR #20873; taking a minimal fix
rather than the broader structured-failure refactor proposed there.
