* feat(core): add git-backed memory repos and block manager Introduce a GCS-backed git repository per agent as the source of truth for core memory blocks. Add a GitEnabledBlockManager that writes block updates to git and syncs values back into Postgres as a cache. Default newly-created memory repos to the `main` branch. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * feat(core): serve memory repos over git smart HTTP Run dulwich's WSGI HTTPGitApplication on a local sidecar port and proxy /v1/git/* through FastAPI to support git clone/fetch/push directly against GCS-backed memory repos. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): create memory repos on demand and stabilize git HTTP - Ensure MemoryRepoManager creates the git repo on first write (instead of 500ing) and avoids rewriting history by only auto-creating on FileNotFoundError. - Simplify dulwich-thread async execution and auto-create empty repos on first git clone. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): make dulwich optional for CI installs Guard dulwich imports in the git smart HTTP router so the core server can boot (and CI tests can run) without installing the memory-repo extra. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): guard git HTTP WSGI init when dulwich missing Avoid instantiating dulwich's HTTPGitApplication at import time when dulwich isn't installed (common in CI installs). 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): avoid masking send_message errors in finally Initialize `result` before the agent loop so error paths (e.g. approval validation) don't raise UnboundLocalError in the run-tracking finally block. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): stop event loop watchdog on FastAPI shutdown Ensure the EventLoopWatchdog thread is stopped during FastAPI lifespan shutdown to avoid daemon threads logging during interpreter teardown (seen in CI unit tests). 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * chore(core): remove send_*_message_to_agent from SyncServer Drop send_message_to_agent and send_group_message_to_agent from SyncServer and route internal fire-and-forget messaging through send_messages helpers instead. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): backfill git memory repo when tag added When an agent is updated to include the git-memory-enabled tag, ensure the git-backed memory repo is created and initialized from the agent's current blocks. Also support configuring the memory repo object store via LETTA_OBJECT_STORE_URI. 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): preserve block tags on git-enabled updates When updating a block for a git-memory-enabled agent, keep block tags in sync with PostgreSQL (tags are not currently stored in the git repo). 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * chore(core): remove git-state legacy shims - Rename optional dependency extra from memory-repo to git-state - Drop legacy object-store env aliases and unused region config - Simplify memory repo metadata to a single canonical format - Remove unused repo-cache invalidation helper 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> * fix(core): keep PR scope for git-backed blocks - Revert unrelated change in fire-and-forget multi-agent send helper - Route agent block updates-by-label through injected block manager only when needed 👾 Generated with [Letta Code](https://letta.com) Co-Authored-By: Letta <noreply@letta.com> --------- Co-authored-by: Letta <noreply@letta.com>
