- Fix dual CLI entry points with semantic drift by making Typer single dispatcher - Fix thread-unsafe module-level lazy state with proper synchronization - Fix closed framework-adapter registry with proper registry pattern and entry points Addresses core architecture violations of protocol-driven core, performance-first, and multi-agent + async safe by default principles. Fixes #1533 Co-authored-by: MervinPraison <MervinPraison@users.noreply.github.com>
📝 WalkthroughWalkthroughThe PR applies thread-safety and control-flow hardening across the codebase: it guards telemetry defaults with a lock, consolidates CLI dispatch to Typer with a narrow legacy shim, makes async primitives and background loop operations loop-aware and locked, centralizes optional-dependency lazy loading into a locked cache, and introduces a thread-safe FrameworkAdapterRegistry plus safer integrations registry mutations.

Code Review
This pull request introduces thread-safe telemetry initialization, a centralized lazy-loading infrastructure, and a registry pattern for framework adapters. The CLI entry point was refactored to use Typer as the primary dispatcher. Feedback indicates that the new CLI routing logic incorrectly identifies hyphenated subcommands as legacy invocations due to the use of isidentifier(). Additionally, the thread-safety implementation in the integrations registry is incomplete, as several methods still access shared state without locking.

The use of isidentifier() here is problematic for CLI subcommands. Many valid subcommands in PraisonAI (and Typer/Click apps in general) contain hyphens (e.g., create-agent, list-agents), which are not valid Python identifiers. This check will incorrectly route such commands to the legacy CLI path, breaking the intended architectural change where Typer should be the single dispatcher for all subcommands.
To correctly identify legacy invocations (bare prompts or YAML files) without breaking hyphenated subcommands, you should rely on the presence of spaces or specific file extensions.

While adding synchronization to register and unregister is a good step towards thread safety, the implementation is incomplete. Other methods in this class, such as list_registered and get_available (not shown in this diff but part of the same class), still access and iterate over self._integrations without acquiring the lock. This can lead to RuntimeError: dictionary changed size during iteration if a registration occurs concurrently with a listing or availability check. For full thread safety, all access to the shared _integrations dictionary should be protected by the lock.
Greptile SummaryThis PR addresses three architectural gaps in the wrapper layer: double-checked locking for telemetry, consolidated thread-safe lazy loading in
Confidence Score: 3/5Not safe to merge — two P1 regressions break litellm/openai availability checks and silence the wrong-loop guard in the scheduler. The thread-safety improvements are well-structured, but the refactor introduced two concrete runtime bugs: missing

runningcheck + docstring now overstates safety.After the refactor,
runningat lines 96-100 is computed but never branched on — pure dead code. More importantly, the docstring (lines 78-83) still claims this is "safe inside a running loop" and describes a distinct "If a loop is running" path. With the new unconditional submit-then-fut.result()flow, callingrun_syncfrom inside a running event loop will block that loop’s thread onfut.result(timeout=timeout), which can deadlock the caller’s loop. Either restore the running-loop guard (raisingRuntimeErrorwhen called from within a running loop) or drop the stale claims from the docstring so callers aren’t misled.♻️ Proposed fix

- Around line 17-33: The current _is_legacy_invocation scans for the first
non-flag token and treats many option values as legacy; change it to only
inspect the very first argv element (the first positional) and treat flags or
option values as non-legacy: if argv is empty or argv[0] starts with "-" return
False; otherwise consider argv0 legacy only if it is a YAML filename that
actually exists on disk (use os.path.exists) or it contains whitespace
(free-text prompt); remove the broad "not arg.isidentifier()" check so
non-identifiers do not automatically trigger legacy routing.

- Around line 116-128: The scheduler can be stopped from a different event loop

the same loop bound by _ensure_async_primitives: inside stop(), call
asyncio.get_running_loop() and assert it is self._bound_loop (or raise a clear
RuntimeError) before calling self._cancel_event.set(), and optionally add a
clarifying docstring on the class or stop() mentioning the
single-loop-per-scheduler contract; reference the _ensure_async_primitives,
stop, _bound_loop, and _cancel_event symbols when making the change.

loader argument causes TypeError at runtime
_load_optional("litellm") and _load_optional("openai") are called without the required loader argument. The _load_optional signature is def _load_optional(key: str, loader): — loader has no default. When the cache key is absent (i.e., on the very first call), Python raises TypeError: _load_optional() missing 1 required positional argument: 'loader' before any availability check can complete.
Since nothing else pre-populates the "litellm" or "openai" cache keys, both _check_litellm_available() and _check_openai_available() are completely broken, and _get_litellm() will also always fail with TypeError rather than the intended ImportError.

RuntimeError is silently caught and dropped
The raise RuntimeError(...) on line 203 (wrong-loop guard) propagates into the enclosing except RuntimeError: pass on line 207, so calling stop() from a different event loop silently proceeds instead of raising. The intent was to catch only asyncio.get_running_loop()'s RuntimeError (no running loop), but the bare except RuntimeError also swallows the deliberate guard.
Fix: catch the RuntimeError from get_running_loop before raising the guard separately.

- Line 69: Add an explicit return type annotation and a short comment
documenting expected return values for praison.main() (it returns None, False,
or success strings) and clarify the exit-code mapping near the 'code = 0 if
result is None else (1 if result is False else 0)' line; specifically, annotate
praison.main as returning Optional[Union[bool, str]] (or similar) and add a
one-line comment above the 'code = ...' assignment that explains None and string
=> exit 0, False => exit 1.
In `@src/praisonai/praisonai/_async_bridge.py`:
- Around line 95-109: The new run_sync() check breaks the sync wrappers in
async_mongodb because methods like get, set, delete unconditionally call
run_sync() even when invoked from a running event loop; update async_mongodb so
each sync wrapper (get, set, delete, etc.) detects an active event loop (via
asyncio.get_running_loop()) and either (a) raise a clear RuntimeError directing
callers to use the async counterparts (async_get, async_set, async_delete) or
(b) rename the sync wrappers (e.g., get_sync, set_sync, delete_sync) to
discourage async use — pick one strategy and apply it consistently; for
surrealdb, only add a similar guard inside __init__ or its sync factory path
if/when async instantiation becomes supported to avoid blocking an event loop.
In `@src/praisonai/praisonai/async_agent_scheduler.py`:
- Around line 198-209: The loop-consistency check in
async_agent_scheduler.stop() currently raises a RuntimeError that's immediately
caught by the same except, making the guard a no-op; fix it by isolating the
call to asyncio.get_running_loop() inside its own try/except (catch only the "no
running loop" case) and perform the self._bound_loop mismatch check afterwards
so that a mismatch raises (or re-raises) the RuntimeError instead of being
swallowed; reference the stop() method, self._bound_loop, and
asyncio.get_running_loop() when making this change.
In `@src/praisonai/praisonai/auto.py`:
- Around line 173-206: The calls to _load_optional are missing the required
loader argument causing a TypeError; update _check_litellm_available,
_get_litellm and _check_openai_available to pass a loader function to
_load_optional (e.g., a lambda or small function that imports/constructs the
needed module) — for example use a loader that does __import__("litellm") for
litellm and for openai either import the module or reuse create_openai_client as
the loader in _get_openai_client; ensure _get_litellm and _get_openai_client
continue to raise the same ImportError message if _load_optional returns None.
In `@src/praisonai/praisonai/framework_adapters/registry.py`:
- Around line 137-146: The lookup checks self._adapters under self._lock but
builds sorted(self._adapters) outside the lock, which can raise during the
ValueError path; while still holding self._lock capture a stable snapshot (e.g.,
names = sorted(self._adapters)) and use that in the raise. Update the code in
the method that does the lookup (the block using self._lock and returning
adapter_class()) so that the sorted list of registered names is computed before
releasing the lock and then included in the ValueError message; this prevents
concurrent register()/unregister() from causing a RuntimeError during error
reporting.

filenames ending in .yaml/.yml while mocking os.path.isfile to return
True/False; (2) verify main() prints version for "--version" and "-V" by mocking
sys.argv and patching praisonai.version.__version__; (3) verify legacy routing
by mocking sys.argv to a bare prompt and to a YAML filename, patching
praisonai.cli.main.PraisonAI to return None/False or raise SystemExit to assert
exit code normalization (None→0, False→1, SystemExit handled) and that sys.argv
is restored after invocation; and (4) verify Typer dispatch path by patching
praisonai.cli.app.app and praisonai.cli.app.register_commands to ensure

The exit code logic correctly handles actual return values from praison.main(), despite implicit typing.
The return values from main() are None, False, or success message strings (e.g., "test", "File ... created successfully"). The mapping code = 0 if result is None else (1 if result is False else 0) correctly converts:
None→ 0 (success)False→ 1 (failure)- Strings (success messages) → 0 (success)
No True or explicit failure values are returned by main(), so the implicit handling works correctly in practice. Consider adding a type hint or comment documenting the expected return type for clarity.

Run_sync() hardening breaks sync wrappers in async contexts—but scope is narrower than stated.
The new check unconditionally raises RuntimeError when called from a running event loop. However, your three examples have different risk profiles:
-
agents_generator.py:817 —
_run_autogen_v4()is dead code; it's never called anywhere in the codebase. No action needed. -
surrealdb.py:78 — Only instantiated via the sync factory (factory.py, line 63), which is CLI-driven. No evidence of async instantiation in the codebase today. Low risk, but the learnings require sync/async conversions to respect the caller's execution context; init blocking the event loop would be unsafe if instantiation ever occurs async.
-
async_mongodb.py — More serious: sync wrapper methods (get, set, delete, etc.) unconditionally call
run_sync(), violating the learnings principle that "all operations must fire in the current execution context." If these sync methods are ever called from async code (which the method names invite), they will now fail. The async variants (async_get,async_set, etc.) exist and should be used instead in async contexts.
Recommended fix: For async_mongodb, either rename sync wrappers to discourage async use (e.g., get_sync()), add runtime guards like a2u_server.publish_sync does, or remove them and require explicit await calls. For surrealdb, add a guard only if async instantiation becomes possible.

run_sync() check breaks the sync wrappers in async_mongodb because methods like
get, set, delete unconditionally call run_sync() even when invoked from a
running event loop; update async_mongodb so each sync wrapper (get, set, delete,
etc.) detects an active event loop (via asyncio.get_running_loop()) and either
(a) raise a clear RuntimeError directing callers to use the async counterparts
(async_get, async_set, async_delete) or (b) rename the sync wrappers (e.g.,
get_sync, set_sync, delete_sync) to discourage async use — pick one strategy and
apply it consistently; for surrealdb, only add a similar guard inside __init__
or its sync factory path if/when async instantiation becomes supported to avoid
blocking an event loop.

Loop-consistency check is silently swallowed — guard is a no-op.
The explicit raise RuntimeError(...) inside the try: block is caught by the very same except RuntimeError: pass that is intended to handle the "no running loop" case. Since stop() is async def, asyncio.get_running_loop() always succeeds here, so the only RuntimeError that can reach the except is the intentional loop-mismatch one — which is then swallowed. The protective guard added in commit 83fd376 therefore does nothing, and callers on a different loop will silently set a stale _cancel_event, which is exactly the bug the change was meant to prevent.
