Fixes #6672 Memory providers now receive on_session_switch() whenever AIAgent.session_id rotates mid-process — /resume, /branch, /reset, /new, and context compression. Before this, providers that cached per-session state in initialize() (Hindsight's _session_id, _document_id, accumulated _session_turns, _turn_counter) kept writing into the old session's record after the agent had moved on. MemoryProvider ABC ------------------ - New optional hook on_session_switch(new_session_id, *, parent_session_id='', reset=False, **kwargs) with no-op default for backward compat. reset=True signals /reset or /new — providers should flush accumulated per-session buffers. reset=False for /resume, /branch, compression where the logical conversation continues. MemoryManager ------------- - on_session_switch() fans the hook out to every registered provider. Isolated try/except per provider — one bad provider can't block others. - Empty/None new_session_id is a no-op to avoid corrupting provider state during shutdown paths. run_agent.py ------------ - _sync_external_memory_for_turn now passes session_id=self.session_id into sync_all() and queue_prefetch_all(). Providers with defensive session_id updates in sync_turn (Hindsight already had this at plugins/memory/hindsight/__init__.py:1199) now actually receive the current id. - Compression block at ~L8884 already notified the context engine of the rollover; now also calls _memory_manager.on_session_switch(reason='compression'). cli.py ------ - new_session() fires reset=True, reason='new_session' so providers flush buffers. - _handle_resume_command fires reset=False, reason='resume' with the previous session as parent_session_id. - _handle_branch_command fires reset=False, reason='branch' with the parent session_id already captured for the DB parent link. gateway/run.py -------------- - _handle_resume_command now evicts the cached AIAgent, mirroring /branch and /reset. The next message rebuilds a fresh agent whose memory provider initialize() runs with the correct session_id — matches the pattern the gateway already uses for provider state cross-session transitions. Hindsight reference implementation ---------------------------------- - plugins/memory/hindsight/__init__.py adds on_session_switch that: updates _session_id, mints a fresh _document_id (prevents vectorize-io/hindsight#1303 overwrite), and clears _session_turns / _turn_counter / _turn_index so in-flight batches don't flush under the new document id. parent_session_id only overwritten when provided (avoids clobbering on a bare switch). Tests ----- - tests/agent/test_memory_session_switch.py: new dedicated file. ABC default no-op, manager fan-out, failure isolation, empty-id no-op, session_id propagation through sync_all/queue_prefetch_all, Hindsight state transitions for every reset/non-reset case, parent preservation. - tests/cli/test_branch_command.py: new test verifying /branch fires the hook with correct parent_session_id + reset=False + reason. - tests/gateway/test_resume_command.py: new test verifying /resume evicts the cached agent. - tests/run_agent/test_memory_sync_interrupted.py: updated existing assertions to account for the session_id kwarg on sync_all and queue_prefetch_all. E2E verified (real imports, tmp HERMES_HOME): - /resume: session_id updates, doc_id fresh, buffers cleared, parent set - /branch: session_id forks, parent links to original - /new: reset=True clears accumulated state - compression: reason='compression' propagated, lineage preserved - Empty id: no-op, state preserved - Legacy provider without on_session_switch: no crash Reported by @nicoloboschi (Hindsight maintainer); related scope-widening comment by @kidonng extending coverage to compression. |
