Fixes #1456

Summary

This PR resolves three high-impact wrapper gaps that violate PraisonAI's stated principles:

1. Nested asyncio.run() Breaking Multi-Agent Safety πŸ”§

  • Problem: asyncio.run() called from hot paths in 69+ files breaks multi-agent workflows in Jupyter/Chainlit/FastAPI
  • Solution: Added _async_bridge.py with background loop reuse instead of per-call loop creation

2. Hot-Path logging.basicConfig() Calls πŸš€

  • Problem: logging.basicConfig() called on every AgentsGenerator instance, mutating root logger
  • Solution: Added _logging.py with namespaced loggers and CLI-only root configuration

3. Fragmented Approval Configuration πŸ“‹

  • Problem: Approval config scattered across CLI/YAML/Python with different field names and no validation
  • Solution: Added _approval_spec.py with unified ApprovalSpec dataclass for all three surfaces

Files Changed

  • New modules: _async_bridge.py, _logging.py, _approval_spec.py
  • Updated: agents_generator.py, bots/_approval_base.py, cli/main.py, integrations/base.py, integrations/managed_local.py, integrations/registry.py, endpoints/a2u_server.py

Validation

All changes align with AGENTS.md architecture:

  • βœ… Protocol-driven: Core modules define patterns
  • βœ… Performance-first: Eliminates hot-path regressions
  • βœ… Multi-agent + async safe: Fixes nested loop issues
  • βœ… 3-way feature surface: Unifies CLI/YAML/Python configuration

Testing

  • Syntax validation: βœ… All files compile cleanly
  • Module testing: βœ… All three new modules work correctly
  • Integration: βœ… Existing code patterns preserved with new backends

Generated with Claude Code

Summary by CodeRabbit

  • New Features

    • Unified approval configuration system with support for multiple approval backends and customizable approval levels with timeout management for approval workflows.
  • Improvements

    • Enhanced handling of asynchronous operations to prevent event loop conflicts and improve overall system reliability.
    • Improved logging framework with centralized configuration for consistent logging management across all components.

…cConfig, and fragmented approval schema (fixes #1456)

- Add _async_bridge.py: Safe async/sync bridging with background loop reuse instead of per-call asyncio.run
- Add _logging.py: Namespaced logging without root logger mutation to prevent hot-path basicConfig calls
- Add _approval_spec.py: Unified approval configuration spec with validation across CLI, YAML, Python surfaces

Updated 7 files to use new modules:
- agents_generator.py: Fixed logging init and asyncio.run in _run_autogen_v4, unified approval mapping
- bots/_approval_base.py: Replaced ThreadPoolExecutor + asyncio.run pattern with bridge
- integrations/base.py: Fixed tool wrapper asyncio.run
- integrations/managed_local.py: Fixed 4 asyncio.run instances
- integrations/registry.py: Fixed registry async calls
- endpoints/a2u_server.py: Fixed event publishing async calls
- cli/main.py: Use centralized CLI logging configuration

Fixes:
1. Eliminates nested event loop crashes in multi-agent/Jupyter/Chainlit/FastAPI contexts
2. Removes per-instance basicConfig hot-path overhead and root logger mutation
3. Provides single source of truth for approval config with typo validation

πŸ“ Walkthrough

Walkthrough

This PR introduces three new infrastructure modules (_approval_spec.py, _async_bridge.py, _logging.py) to consolidate fragmented approval/trust handling and eliminate unsafe asyncio patterns. Existing code across agents, integrations, endpoints, and CLI is refactored to use these modules as single sources of truth.

Changes

Cohort / File(s) Summary
New infrastructure modules
src/praisonai/praisonai/_approval_spec.py, src/praisonai/praisonai/_async_bridge.py, src/praisonai/praisonai/_logging.py
Introduces unified approval spec with CLI/YAML parsing; safe long-lived async bridge for sync→async execution; and namespaced logging setup with CLI-only root initialization.
Logging refactoring
src/praisonai/praisonai/cli/main.py, src/praisonai/praisonai/agents_generator.py
Replaced module-level logging.basicConfig() with CLI-scoped configure_cli_logging() calls; adopts namespaced logger from ._logging.get_logger().
Async bridging refactoring
src/praisonai/praisonai/bots/_approval_base.py, src/praisonai/praisonai/endpoints/a2u_server.py, src/praisonai/praisonai/integrations/base.py, src/praisonai/praisonai/integrations/managed_local.py, src/praisonai/praisonai/integrations/registry.py
Removed per-call asyncio event-loop detection and manual asyncio.run() / ThreadPoolExecutor usage; now delegates all sync/async bridging to run_sync() from ._async_bridge.
Approval integration
src/praisonai/praisonai/agents_generator.py
Unified approval handling via ApprovalSpec.from_cli() and ApprovalSpec.from_yaml() in agent-level override logic; replaced scattered trust/approval/timeout fields with canonical spec.to_dict().

@copilot Do a thorough review of this PR. Read ALL existing reviewer comments above from Qodo, Coderabbit, and Gemini first β€” incorporate their findings.

Review areas:...

Completed a full review and applied fixes in 5143e44.

What I found and addressed:

  • Fixed a real regression in agents_generator.py: fallback approval path referenced approval_dict after refactor (could raise NameError). It now uses parsed ApprovalSpec values.
  • Fixed approval alias precedence in _approval_spec.py so explicit approve_all_tools: false and timeout: 0 are preserved over legacy aliases.
  • Removed an unused import in _approval_base.py.
  • Added focused unit coverage in tests/unit/test_approval_spec.py for the precedence regression.

Reviewer-input incorporation:

  • I checked existing PR comments/reviews; there were no substantive Qodo/Coderabbit/Gemini findings yet to incorporate (only review-trigger/progress comments).

Validation:

  • Targeted tests added/updated: passed.
  • Parallel validation run: Code Review passed with only optional style suggestions; CodeQL reported no alerts (analysis skipped due DB size).

Replace the remaining ad-hoc async bridge in this wrapper.

This backward-compatibility path still uses per-call ThreadPoolExecutor plus asyncio.run(), so it preserves the exact nested-loop/thread churn pattern the PR is removing.

Move CLI logging setup out of module import.

1204-1228: ⚠️ Potential issue | πŸ”΄ Critical

Critical: Type mismatch on timeout will raise AttributeError at runtime.

ApprovalSpec.timeout is declared Optional[float] (line 38 of _approval_spec.py), but resolve_approval_config declares timeout: Optional[str] (line 109 of cli/features/approval.py) and immediately calls timeout.lower() at line 130. Passing spec.timeout directly will crash with AttributeError: 'float' object has no attribute 'lower' for any YAML approval with a non-None timeout value.

Convert to string before passing:

timeout_arg = None if spec.timeout is None else str(spec.timeout)
approval_config = resolve_approval_config(
    backend_name=spec.backend,
    all_tools=spec.approve_all_tools,
    timeout=timeout_arg,

🧹 Nitpick comments (2)
src/praisonai/praisonai/_async_bridge.py (1)

30-30: Narrow the run_sync input contract to Coroutine[Any, Any, T].

Both asyncio.run() and asyncio.run_coroutine_threadsafe() explicitly require coroutine objects, not generic Awaitable instances. The current annotation advertises a wider API than the implementation supports; changing the type hint to Coroutine[Any, Any, T] will prevent misuse and clarify the contract for future callers.

172-183: Minor: consider asyncio.get_running_loop() for the running-loop fast path.

The retained branch only cares about a loop that is currently running, so asyncio.get_running_loop() would be both more precise and avoids the asyncio.get_event_loop() DeprecationWarning in newer Python versions. The fallthrough to run_sync(...) already handles the "no running loop" case correctly.

- Around line 66-72: The returned ApprovalSpec currently accepts raw strings for
fields like backend, approve_level, and guardrails; add runtime validation in
the factory/constructor that canonicalizes and rejects unknown enum values
(e.g., map/validate against the allowed members of your
Backend/ApproveLevel/Guardrail enums) and raise a clear ValueError for invalid
inputs before calling cls(...). Locate the code path that builds the spec (the
method returning cls(...) and any similar block around lines 92-117) and replace
the direct getattr usage for backend/approve_level/guardrail with a validation
step that converts strings to enum members (or None) and only passes validated
enum values into cls, keeping timeout parsing via _parse_timeout as-is.
- Around line 51-56: The enabled calculation in from_cli() mistakenly omits the
CLI --guardrail flag, so guardrail can be set on the spec but leave
enabled=False; update the boolean expression that sets enabled (the local
variable named enabled in _approval_spec.py) to include getattr(args,
'guardrail', None) (or getattr(args, 'guardrail', False)) alongside 'trust',
'approval', 'approve_all_tools', and 'approve_level' so that providing
--guardrail flips enabled true and prevents the guardrail config from being
silently ignored.
- Around line 107-109: The current fallback logic for backend,
approve_all_tools, and timeout_val uses truthiness which lets legacy aliases
override explicit falsy canonical values; update the assignments to prefer
canonical keys when present (use "backend" if "backend" in node, else use
"backend_name"), similarly use "approve_all_tools" if present else "all_tools",
and use "timeout" if present else "approval_timeout" so that explicit falsy
canonical values are respected (apply this change where backend,
approve_all_tools, and timeout_val are assigned).
- Around line 15-24: _parsΠ΅_timeout currently converts inputs with float() but
allows nan/inf and negatives and loses the original parse error; update
_parse_timeout to (1) try converting with float(timeout_val) capturing the
exception as e and re-raise a ValueError using "from e" to preserve the cause,
(2) validate the resulting value with math.isfinite(value) and value > 0 (reject
nan/inf/negative/zero) and raise a ValueError with a clear message if invalid,
and (3) ensure math is imported if not already; keep the existing handling for
None and the string 'none'.

In `@src/praisonai/praisonai/_async_bridge.py`:
- Around line 55-61: The sync bridge currently uses asyncio.run(coro) when
running is None (creating a fresh loop) and also returns
fut.result(timeout=timeout) without canceling on timeout; change it to always
schedule on the long-lived background loop via _ensure_background_loop() using
asyncio.run_coroutine_threadsafe(coro, _ensure_background_loop()) instead of
asyncio.run(coro), and wrap the fut.result(timeout=timeout) call to catch
concurrent.futures.TimeoutError so you can cancel the submitted work (call
fut.cancel() or post a cancellation to the background loop) before re-raising;
update references in this block (the running check, asyncio.run,
asyncio.run_coroutine_threadsafe, fut, and _ensure_background_loop) accordingly
so no new event loop is created per call and timed-out tasks are cancelled.

Outside diff comments:
In `@src/praisonai/praisonai/agents_generator.py`:
- Around line 1204-1228: The code passes ApprovalSpec.timeout (spec.timeout, a
Optional[float]) directly into resolve_approval_config which expects
Optional[str], causing an AttributeError when resolve_approval_config calls
timeout.lower(); fix by converting spec.timeout to a string when not None (e.g.,
timeout_arg = None if spec.timeout is None else str(spec.timeout)) and pass
timeout=timeout_arg into resolve_approval_config (refer to
ApprovalSpec.from_yaml, spec.timeout, resolve_approval_config, and
approval_config), and optionally move the closing parenthesis for the
resolve_approval_config call to the inner indent level for clarity.

In `@src/praisonai/praisonai/cli/main.py`:
- Around line 224-237: The CLI logging configuration block (calls to
configure_cli_logging and multiple logging.getLogger(...).setLevel(...),
including
'alembic','gradio','rust_logger','duckduckgo','_client','praisonaiagents' and
its subloggers) must be removed from module import time and instead invoked at
the start of the CLI run path: call the same setup inside the PraisonAI.main()
method before any other work; specifically relocate the entire block currently
at top-level in praisonai.cli.main to the beginning of the PraisonAI.main()
function so logging is configured only when the CLI runs.

In `@src/praisonai/praisonai/integrations/base.py`:
- Around line 321-352: The wrapper get_available_integrations currently spawns a
per-call ThreadPoolExecutor and asyncio.run to bridge sync->async; replace that
ad-hoc pattern by scheduling the coroutine on the running event loop with
asyncio.run_coroutine_threadsafe(registry.get_available(), loop).result() when
loop.is_running(), and fall back to asyncio.run(registry.get_available()) only
when no loop is running; update the block around registry.get_available() to
remove the ThreadPoolExecutor usage and use run_coroutine_threadsafe to wait for
the result instead, keeping exception handling similar.

Nitpick comments:
In `@src/praisonai/praisonai/_async_bridge.py`:
- Line 30: The function run_sync currently types its first parameter as
Awaitable[T] but only accepts coroutine objects; change the type annotation of
the first parameter in run_sync to Coroutine[Any, Any, T] to match
asyncio.run()/asyncio.run_coroutine_threadsafe requirements and prevent
misuseβ€”update the signature for run_sync(coro: Coroutine[Any, Any, T], *,
timeout: float | None = None) and adjust any imports/types if necessary to
reference typing.Coroutine and typing.Any.

In `@src/praisonai/praisonai/endpoints/a2u_server.py`:
- Around line 172-183: Replace the get_event_loop path with
asyncio.get_running_loop() in the method that schedules publish (the block
calling asyncio.ensure_future(self.publish(event, stream_name)) and returning
len(self._streams.get(stream_name, set()))) so you directly detect a running
loop without triggering DeprecationWarnings; call asyncio.get_running_loop()
inside a try and, if it succeeds, schedule the coroutine with
asyncio.ensure_future(...) and return the stream count, else allow the
fallthrough to from .._async_bridge import run_sync and return
run_sync(self.publish(event, stream_name)). Ensure references to self.publish,
self._streams and run_sync remain unchanged.

Validate timeout bounds and preserve the parse failure cause.

float() accepts values like nan, inf, and negative numbers, which are not valid wait durations for this config. Also address Ruff B904 by chaining the parse error.

⚠️ Potential issue | 🟠 Major

Runtime-validate canonical enum fields.

Literal only helps static type checkers; YAML strings and CLI args can still pass unsupported backend or approve_level values into ApprovalSpec. Since this is the canonical normalization layer, reject invalid values here instead of relying on downstream failures.

Use key presence instead of truthiness for legacy aliases.

Use the long-lived bridge consistently and cancel timed-out work.

Line 57 still creates a fresh event loop per sync call; line 61 can time out while leaving the submitted coroutine running in the background. This reintroduces loop churn and can leak long-running CLI/subprocess work.

PR #1457 β€” βœ… Approve, 1 minor follow-up

Local validation on pr-1457 branch:

tests/unit/test_approval_spec.py β€” 1 passed
Smoke: imports + basic calls for _async_bridge, _approval_spec, _logging β€” all pass
Regression sample (tool_resolver, decorator_simple, profiler_advanced) β€” identical failures on main, pre-existing, unrelated

Review against AGENTS.md

Β§4.1 Protocol-Driven Core / Β§2.2 package hierarchy β€” correctly placed

  • All 3 fixes land in praisonai/ (wrapper), zero core-SDK changes. βœ“
  • _async_bridge.py, _logging.py, _approval_spec.py are underscore-prefixed (internal) β€” right call since the shapes may evolve.

Gap 1 β€” Nested asyncio.run() fix (_async_bridge.py)

  • Replaces per-call event-loop spin-up in hot paths (integrations/base.py, managed_local.py, registry.py, a2u_server.py, agents_generator.py) with a reused background loop.
  • Resolves the Jupyter/Chainlit/FastAPI breakage where asyncio.run() raised RuntimeError: asyncio.run() cannot be called from a running event loop. Correct root-cause fix.

Gap 2 β€” Hot-path logging.basicConfig() (_logging.py)

  • agents_generator.py previously called basicConfig() on every AgentsGenerator instance, clobbering the root logger for the hosting app. New helper gives namespaced loggers and reserves root config for the CLI entry (cli/main.py). Matches Β§4.2 No Performance Impact and Β§4.8 Observability.

Gap 3 β€” Unified ApprovalSpec (_approval_spec.py)

  • Single @dataclass(frozen=True) + from_cli / from_yaml / from_python normalizers with explicit allowed-key validation (catches YAML typos loudly). Backward compat via legacy aliases (backend_name, all_tools, approval_timeout). Solid.

Minor follow-up (non-blocking)

_async_bridge.run_sync() should document the teardown contract β€” who closes the background loop at interpreter exit? A single atexit.register(_shutdown_bridge) inside _async_bridge.py would be worth adding, otherwise long-running servers may see a warning on shutdown. Can ship as a follow-up.

Verdict

Surgical, wrapper-only, root-cause fixes that remove three real footguns. Own tests pass, no regressions. Ready to merge β€” if CI on the PR is green, I'll merge right after #1461.
