jnMetaCode dcffb5269a fix: only pass dimensions when explicitly configured in embedding config (#6432)
* fix: only pass dimensions param when explicitly configured

Models like bge-m3 don't support the dimensions parameter in the
embedding API, causing HTTP 400 errors. Previously dimensions was
always sent with a default value of 1024, even when the user never
configured it. Now dimensions is only included in the request when
embedding_dimensions is explicitly set in provider config.

Closes #6421

Signed-off-by: JiangNan <1394485448@qq.com>

* fix: handle invalid dimensions config and align get_dim return

- Add try-except around int() conversion in _embedding_kwargs to
  gracefully handle invalid embedding_dimensions config values
- Update get_dim() to return 0 when embedding_dimensions is not
  explicitly configured, so callers know dimensions weren't specified
  and can handle it accordingly
- Both methods now share consistent logic for reading the config

* fix: improve logging for invalid embedding_dimensions configuration

Yufeng He acbc5150cf fix: SQLite 'database is locked' by adding busy timeout (#6474)
The async engine is created without a busy timeout, so concurrent
writes (agent responses, metrics, session updates) fail instantly
with 'database is locked' instead of waiting for the lock.

Add connect_args={'timeout': 30} for SQLite engines so the driver
waits up to 30 seconds for the write lock. Combined with the existing
WAL journal mode, this handles the typical concurrent write bursts
from agent + metrics + session operations.

Fixes #6443

qingyun e77500ff69 fix(provider): sync providers_config after creating new provider (#6388)
Fixes #6283

When adding a new embedding provider, the knowledge base creation page
did not show the new provider until restart.

Root cause: create_provider() did not update self.providers_config,
which is used by get_provider_config_list() to return provider lists.

This fix syncs the in-memory config after loading the new provider,
consistent with how reload() handles config updates.

Yufeng He d87cf897da Fix TypeError when API returns null choices (#6313)
* Fix CreateSkillPayloadTool array schema missing items field

The payload parameter's anyOf array variant lacked an items field,
causing Gemini API to reject the tool declaration with 400 Bad Request:
'parameters.properties[payload].any_of[1].items: missing field.'

Add items: {type: object} to the array variant to satisfy the Gemini
API requirement for array type schemas.

Fixes #6279

* Fix TypeError when OpenAI-compatible API returns null choices

Some providers (e.g. OpenRouter) may return a completion where
choices is None rather than an empty list — for instance on rate
limiting, content filtering, or transient errors. The existing code
used len(completion.choices) which throws TypeError on None.

Replace all len(...choices) == 0 checks with 'not ... .choices' which
handles both None and empty list. Affects _query_stream, _parse_openai_completion,
and _extract_reasoning_content.

qingyun 18a99a25c2 fix(platform): parse QQ official face messages to readable text (#6355)
Fixes #6294

QQ official bot receives emoji/sticker messages as raw XML-like tags:
`<faceType=4,faceId="",ext="eyJ0ZXh0IjoiW+a7oeWktOmXruWPt10ifQ==">`

This made the LLM unable to understand the emoji content.

Changes:
- Added `_parse_face_message()` method to parse face message format
- Decode base64 `ext` field to get emoji description text
- Replace face tags with `[表情:描述]` format for readability

Example:
- Input: `<faceType=4,faceId="",ext="eyJ0ZXh0IjoiW+a7oeWktOmXruWPt10ifQ==">`
- Output: `[表情:[满头问号]]`

eason dd6bc1dcdb fix: add missing spaces in cron prompt and replace deprecated utcnow() (#6192)
1. Fix missing spaces in cron job wake prompt string concatenation.
   Python implicit string concatenation produced:
   "...scheduled taskProceed..." and "...conversation.After..."
   which sent garbled instructions to the LLM agent, causing unreliable
   cron job execution.

2. Replace deprecated datetime.utcnow() with
   datetime.now(datetime.timezone.utc) in JWT generation.
   utcnow() is deprecated since Python 3.12 and returns naive datetime
   which can cause incorrect token expiry on non-UTC systems.

Closes #6103
Closes #6165

eason 86ef758a9a fix: prevent ValueError when removing already-removed API key in retry loop (#6193)
In _handle_api_error(), when a 429 rate-limit is encountered, the code
calls available_api_keys.remove(chosen_key). If the same key was already
removed in a previous retry iteration (e.g. the key rotated back to the
same value), this raises ValueError which crashes the entire LLM request
with an opaque error instead of a proper retry/fallback.

Add a membership check before calling remove() to prevent the crash.

- Remove .strip() from Plain.toDict() to match async to_dict() behavior
- Fixes #6237: QQ @mentions no longer lose trailing spaces

* refactor: remove redundant to_dict() from Plain class

- Let Plain inherit to_dict() from BaseMessageComponent
- BaseMessageComponent.to_dict() calls toDict() by default
- Reduces code duplication and prevents future divergence
- Addressed code review feedback from @gemini-code-assist and @sourcery-ai

* feat: add async to_dict method to Plain message component

* fix: add return type hint to Plain.toDict method

2ndelement e6c1164755 perf(QQ Official API): improve streaming message delivery reliability and proactive media sending (#6131)
* fix(qqofficial): fix streaming message delivery for C2C

* fix(qqofficial): rewrite send_streaming for C2C vs non-C2C split

* fix(qqofficial): add _extract_response_message_id for safe id extraction

* fix(qqofficial): flush stream segment on tool-call break signal

* fix(qqofficial): downgrade rich-media to non-stream send in C2C

* fix(qqofficial): auto-append \n to final stream chunk (state=10)

* fix(qqofficial): propagate stream param to all _send_with_markdown_fallback call sites

* fix(qqofficial): retry on STREAM_MARKDOWN_NEWLINE_ERROR with newline fix

* fix(qqofficial): handle None/non-dict response in post_c2c_message gracefully

* fix(qqofficial): remove msg_id from video/file media payloads in send_by_session

QQ API rejects msg_id on proactive media (video/file, msg_type=7) messages
sent via the tool-call path, returning "请求参数msg_id无效或越权". The
msg_id passive-reply credential is consumed by the first send and cannot be
reused for subsequent media uploads in the same session.

Remove msg_id from the payload after setting msg_type=7 for video and file
sends, for both FRIEND_MESSAGE (C2C) and GROUP_MESSAGE paths.

* fix(qqofficial): replace deprecated get_event_loop() with get_running_loop()

asyncio.get_event_loop() is deprecated since Python 3.10 and raises a
DeprecationWarning (or errors) when called from inside a running coroutine
without a current event loop set on the thread.  Replace both call-sites
in the streaming throttle logic with asyncio.get_running_loop(), which is
the correct API to use inside an already-running async context.
