pipecat-moss: cache_path, load each index once per service, forward frames unchanged - #562
rafaelbeckel wants to merge 6 commits into
Conversation
…rames unchanged MossRetrievalService takes cache_path and falls back to MOSS_PROJECT_ID and MOSS_PROJECT_KEY as the README documents. load_index loads each index once per service and shares in-flight loads, so one service per process serves every bot. MossIndexProcessor forwards the frame it received, which keeps LLMContextFrame.speculation and LLMMessagesUpdateFrame.run_llm. Requires moss 1.14.0 or later.

… setup fails The README snippet uses MOSS_CACHE_PATH with a ./moss-cache default and awaits load_index inside an async bot. The demo cancels and gathers its load task if transport setup fails first, and a shared load's failure no longer needs a caller to retrieve it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

@coderabbitai Thanks for the review. The one actionable comment (writable cache path in the README) is fixed in 6714894. 🤖 Addressed by Claude Code |

@cubic-dev-ai Thanks for the review. All three issues are fixed in 6714894: the README cache path is writable, the README snippet awaits inside an async bot, and the demo cleans up its load task when transport setup fails. 🤖 Addressed by Claude Code |
@rafaelbeckel The three fixes are in place in 6714894 and they look right:
One thing worth confirming since it's easy to get wrong: the cleanup actually preserves the shared load, not just in spirit. No further changes needed from my side. Tip: get faster answers by chatting with cubic’s review copilot in the review UI |

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winRetain the first
auto_refreshoption when retrying a failed load.If the first
load_index(index_name, auto_refresh=...)call fails, the next call replaces the failed task and passes its ownauto_refreshvalue toMossClient.load_index. This allows a later call to change the setting, contrary to the documented first-call contract. Keep the first option associated with the index when replacing a failed task.Suggested fix
- task = asyncio.ensure_future(self._load(index_name, auto_refresh)) + task = asyncio.ensure_future( + self._load(index_name, self._load_options.get(index_name, auto_refresh)) + ) + self._load_options[index_name] = self._load_options.get(index_name, auto_refresh)🤖 Prompt for AI Agents

Summary
pipecat-moss0.0.3, the version on PyPI, cannot be imported on a fresh install. It pinsinferedge-moss, which no longer exportsAddDocumentsOptions, and it imports theopenai_llm_contextmodule thatpipecat-ai1.8 removed. The source here already moved tomossandLLMContextFramebut was never released. This PR adds what the docs need to teach one service per process, and fixes a frame bug.cache_pathonMossRetrievalService, passed to theMossClient. A load in a new process reads an unchanged index from disk instead of downloading it. Requiresmoss1.14.0 or later; the lock moves to 1.19.0.load_indexloads each index once per service. Later and concurrent calls wait for the same load, a bot that disconnects mid-load does not cancel it, and a failed load is retried by the next call.auto_refreshis passed through, so a long-lived process follows new index versions.LLMContextFrameandLLMMessagesUpdateFrame, droppingspeculation(a speculative run then reaches the LLM as a normal turn) andrun_llm. It now pushes the frame it received. This issue was first reported in fix: move off the LLM context frames pipecat removed in 1.8 pipecat-moss#5.MOSS_PROJECT_IDandMOSS_PROJECT_KEYas the README says. Missing credentials raiseValueErrorinstead of failing inside the native client.Notes
