fix: Resolve architectural gaps in registry fragmentation and singleton patterns#1675
Conversation
…on patterns This commit addresses three critical architectural violations identified in issue #1674: **Gap 1 - Registry Consolidation**: Unified four different registry patterns under canonical PluginRegistry: - Enhanced PluginRegistry with alias support for consistent naming - Migrated LLMProviderRegistry from class-level singleton to PluginRegistry inheritance - Converted cli_backends from module-level dict to PluginRegistry pattern - Refactored StoreRegistry to inherit from PluginRegistry instead of duplicating logic **Gap 2 - Singleton Elimination**: Removed process-global singletons for multi-agent safety: - Converted Profiler from __new__ singleton to per-instance with context-aware fallback - Replaced LLMProviderRegistry._instance with module-level default pattern - Added create_exec_approval_manager() for per-agent ExecApprovalManager instances - Refactored telemetry init to avoid process-wide os.environ mutation **Gap 3 - Async Surface**: Added complete async interface to PraisonAIDB adapter: - Implemented aon_* async versions of all lifecycle hooks (aon_user_message, etc.) - Added async context manager support (__aenter__, __aexit__, aclose) - Graceful fallback: async methods detect store capabilities and use asyncio.to_thread for sync stores All changes maintain backward compatibility while enabling proper multi-agent isolation and async safety.

In `@src/praisonai/praisonai/cli_backends/registry.py`:
- Around line 82-88: The except block around registry.resolve(backend_id) /
factory_loader() is currently re-raising a new ValueError and dropping the
original exception context; change the handler to capture the original exception
(e.g., except ValueError as e:) and re-raise the new ValueError using exception
chaining (raise ValueError(f"Unknown CLI backend: {backend_id}. Available:
{available}") from e) so the original traceback is preserved; update the except
ValueError block that contains registry.resolve, factory_loader(), and the raise
ValueError(...) call.
In `@src/praisonai/praisonai/db/adapter.py`:
- Around line 610-632: The async handler aon_agent_message currently builds
ConversationMessage with only role/content/metadata and uses a different import
path; update it to match the sync implementation by importing
ConversationMessage from the same module used by aon_user_message, and populate
the missing required fields when constructing the message: generate a unique id
(e.g. UUID), set session_id to the provided session_id, and set created_at to
the current UTC timestamp; keep the existing async_add_message vs to_thread
fallback logic but pass the fully populated ConversationMessage instance to
_conversation_store.async_add_message or _conversation_store.add_message.
- Around line 587-609: The async handler aon_user_message builds a
ConversationMessage missing required fields and uses a different import path;
update aon_user_message to import ConversationMessage from the same module as
the sync variant (use the ..persistence.conversation.base import path) and
construct the message with the same fields as the sync version: set id (generate
a UUID), session_id (use the session_id arg), role="user", content, metadata
(metadata or {}), and created_at (current UTC datetime) before calling
async_add_message or delegating to to_thread.
- Around line 633-655: The async handler aon_tool_call currently only calls
async_add_tool_call or runs add_tool_call in a thread; to match the sync
on_tool_call behavior, detect when the conversation store lacks add_tool_call
but supports add_message (or async_add_message), build the same
ConversationMessage payload (JSON-serialize the tool call details matching
on_tool_call), and persist it via async_add_message or
asyncio.to_thread(self._conversation_store.add_message, message); reference
aon_tool_call, on_tool_call, _conversation_store, async_add_tool_call,
add_tool_call, add_message, and ConversationMessage when making the change so
async tool calls are stored identically to sync ones.
- Around line 571-586: The code calls non-existent methods async_set_agent_state
/ set_agent_state on self._state_store inside the aon_agent_start flow; replace
those calls with the actual StateStore API (e.g., set() or set_json()) to
persist the agent status payload. Concretely, in the block that checks
self._state_store (and currently references async_set_agent_state and
set_agent_state), call the asynchronous variant if available (await
self._state_store.set_json(key, {"status":"started","metadata": metadata or {}})
or await self._state_store.set(key, value)) and for the sync case use
asyncio.to_thread to call the sync set/set_json equivalent with the same key and
payload; keep the existing session_id / agent_id or name logic to form the key
and ensure the payload is {"status":"started","metadata": metadata or {}} so no
AttributeError occurs at runtime.
In `@src/praisonai/praisonai/gateway/exec_approval.py`:
- Around line 266-280: The get_default_exec_approval_manager function currently
ignores the ttl parameter after the first initialization; update its docstring
to explicitly state: "Note: ttl is only applied when the default manager is
first created. Subsequent calls return the existing instance regardless of ttl."
Additionally, add a runtime warning inside get_default_exec_approval_manager: if
_default_manager is not None and the passed ttl differs from the existing
_default_manager._ttl, emit a warnings.warn describing the mismatch (reference
symbols: get_default_exec_approval_manager, _default_manager, _manager_lock,
ExecApprovalManager, and _ttl) so callers are informed when their ttl is
ignored.

Remove calls to non-existent set_agent_state and async_set_agent_state methods.
The StateStore protocol doesn't define set_agent_state or async_set_agent_state methods. Neither method exists in any StateStore implementation. This code will raise AttributeError at runtime when aon_agent_start() is called. Use the actual StateStore API methods (e.g., set() or set_json()) to store agent state instead.

Major: Inconsistent tool call persistence logic - async may silently fail.
The async version checks for add_tool_call methods, but the sync version (lines 237-268) manually creates a ConversationMessage with JSON-serialized tool data and calls add_message. If stores don't implement add_tool_call (which appears likely based on the sync implementation), the async version will silently do nothing.
This inconsistency means:
- Sync agents persist tool calls as conversation messages
- Async agents may not persist tool calls at all

Document that ttl is only applied during first initialization.
The ttl parameter is only used when first creating the default manager. Subsequent calls with different ttl values will return the existing instance and ignore the new ttl. This could confuse users who expect to reconfigure the TTL.
Consider either:
- Adding a docstring note: "Note:
ttlis only applied when the default manager is first created. Subsequent calls return the existing instance regardless ofttl." - Raising a warning if
ttldiffers from the existing instance's_ttl.

registry.resolve("claude-code") returns the inner factory function (the result of claude_loader() stored by PluginRegistry.__init__ as _items[name] = loader()). Calling factory_loader() on it produces a ClaudeCodeBackend() instance, not another factory, so the subsequent backend = factory() raises TypeError: 'ClaudeCodeBackend' object is not callable.
User-registered backends (via register_cli_backend) store an extra wrapper layer in _items, so their two-call chain works. The built-in path skips that wrapper, making it one call too many. The fix is to align the built-in loader to also return a wrapper: change claude_loader to return a callable that, when invoked, returns factory (i.e., make it a three-level closure like the user-registration path), or collapse resolve_cli_backend to call factory_loader() once for both paths by not treating it as a two-level indirection.

PluginRegistry._load_entry_points() stores ep.load() directly into _items (the raw class or factory returned by the entry point). StoreRegistry.create() then calls factory_loader = self.resolve(name) → factory = factory_loader() → factory(**kwargs). The first call (factory_loader()) treats the entry-point value as a "factory of factories", instantiating or invoking it with no arguments, then treats the result as the store factory. The old _register_entry_points called self.register(ep.name, ep.load()), which stored the factory directly and invoked it once with **kwargs.
Any external package that registers a store via entry points would now get a TypeError or produce the wrong object because the contract changed from one-call to two-call. Built-in stores are unaffected because they go through register_store() which correctly wraps with a factory_loader closure.
