* perf(models): batch-fetch function valves to eliminate N+1 queries
get_action_priority() called Functions.get_function_valves_by_id()
individually for every action on every model — an N+1 query pattern
that issued one DB round-trip per (action x model) pair.
Add Functions.get_function_valves_by_ids() that fetches all valves in
a single WHERE IN query, then look up each action's valves from the
pre-fetched dict inside get_action_priority().
No functional change — same priority resolution, same sort order.
* Update models.py
* Update models.py
Backend emits terminal events for write_file, replace_file_content,
and run_command. Frontend showFileNavDir subscriber uses startsWith
path matching to smartly refresh only when the event is relevant:
- write_file/replace_file_content: refresh if path is in current view
- run_command: always refresh (uses root '/' which matches everything)
- Also adds copy-to-clipboard button and code preview full-height fix
fix: resolve valve priority for actions and filters via class instantiation
The priority sorting for action buttons and filter execution order
read valve data directly from the database JSON column using
Functions.get_function_valves_by_id(). This returns only explicitly
saved values — when a developer defines priority as a class default
in their Valves definition (e.g. priority: int = 5) without ever
opening the Valves UI to persist it, the database column remains
empty. Every function then resolves to priority 0, and the preceding
set() deduplication produces non-deterministic iteration order that
the stable sort preserves — resulting in random button placement on
every page load.
The fix instantiates the Valves class with database values as keyword
overrides: Valves(**(db_valves or {})). This merges any persisted
overrides onto the code-defined defaults, matching the pattern already
established in the action execution handler, filter processing
pipeline, and tool module initialization. A secondary sort key (the
function ID) ensures fully deterministic ordering even when multiple
functions share the same priority value.
Affected locations:
- get_action_priority in utils/models.py (action button ordering)
- get_priority in utils/filter.py (filter execution ordering)
feat: sort action buttons by valve priority
Action buttons under assistant messages were rendered in
non-deterministic order due to set() deduplication. They now
respect the priority field from function Valves, sorted ascending
(lower value = appears first, default 0), matching the existing
filter priority mechanism.
* feat: add LOG_FORMAT env var with JSON formatter for early logging
Introduce LOG_FORMAT environment variable (set to "json" to enable).
When active, logging.basicConfig() uses a JSONFormatter that outputs
single-line JSON objects with fields: ts, level, msg, caller, error,
stacktrace. This covers all log messages emitted during module imports
before Loguru's start_logger() takes over.
* feat: add JSON sink for Loguru when LOG_FORMAT=json
Add _json_sink() as a Loguru sink function that writes single-line JSON
to stdout. In start_logger(), conditionally use the JSON sink instead of
the plain-text stdout_format when LOG_FORMAT is set to "json".
* feat: suppress ASCII banner and fix alembic logging in JSON mode
- Wrap the ASCII art banner print in main.py with a LOG_FORMAT != "json"
guard so JSON output stays machine-parseable.
- Skip alembic's fileConfig() call in migrations/env.py when
LOG_FORMAT=json to prevent it from replacing the JSON log handlers
installed during early startup.
