Main's #60569 (dashboard memory provider switching) rewrote the same
GET/PUT /api/memory/providers/{name}/config routes this PR owns — the
dashboard and desktop share one backend. Resolve by dispatching: providers
that declare a config_schema.py get the declared path (host-block storage,
locked honcho writes, profile scoping, actions); everything else keeps
main's instance get_config_schema()/save_config path unchanged, so the
dashboard's PluginsPage behavior is preserved for instance providers.
Setup manifests, the /setup endpoint, provider switching, and name
validation from #60569 apply to both paths. Instance payloads gain the
docs_url/actions keys the desktop panel expects; declared payloads gain
the setup block the dashboard expects. Main's hindsight/honcho instance-
schema tests are updated for the dispatch, and its status test gets the
HOME pin it was missing (it read the developer's real ~/.honcho).
The salvaged SelfHostedBackend made self-hosted servers reachable via
mem0.json / MEM0_HOST, but the setup wizard still offered only Platform
and OSS — exactly the gap users hit (Discord report: 'At memory setup
there's only 2 options'). Adds a third wizard mode:
- interactive picker: Platform / Self-hosted server / Open Source
- non-interactive: hermes memory setup mem0 --mode selfhosted
--host http://... [--api-key ...] [--dry-run]
- host -> mem0.json (behavioral), API key -> .env as MEM0_API_KEY
(secret), optional key for AUTH_DISABLED servers
- best-effort reachability check against the server, non-fatal
- README + memory-providers docs updated with the wizard path
Review follow-ups on the salvage:
- get_all() pruned from the ABC and all three backends: mem0_list (its
only caller) was removed by the recall-tuning commit, leaving new,
tested, unreachable code — including SelfHostedBackend's _MAX_TOP_K
over-fetch workaround. Tests for it dropped; fake-class stubs remain
harmlessly. (The #52921 true-total fix lives on in the PR history if
a lister ever returns.)
- The persisted rerank config key was write-only (setup prompted for it,
nothing read it). initialize() now parses it into _rerank_default and
mem0_search uses it when the model doesn't pass rerank explicitly;
per-call args still win. Guard test added.
- Platform-mode setup now warns when MEM0_HOST is set in the environment:
the json host-clear can't help there (_load_config seeds host from the
env var, docs tell users to put it in .env) — the user would silently
keep routing to the self-hosted server.
- SelfHostedBackend: connect-level retries (httpx.HTTPTransport(retries=2))
so a single transient blip doesn't count toward the provider breaker;
transport now injectable and the test helper uses the real __init__
instead of mirroring it via __new__.
- plugin.yaml description no longer leads with reranking (off by default,
platform-only); docs em-dash typo fixed.
Follow-up on the salvaged #55614. The PR added host-based routing to
_create_backend (precedence: oss > host > platform) but two sibling surfaces
didn't mirror it:
- system_prompt_block() checked host before oss, so an oss+host config ran
OSS but told the model it was self-hosted HTTP. Reordered to match routing.
- Platform setup (hermes memory setup mem0 --mode platform) left a stale host
in mem0.json; since host beats platform, the user kept routing to the
self-hosted server. save_config merges (no delete), so clear host to ""
rather than pop() so the merge actually overwrites it.
Adds regression tests for both (mutation-checked).
Salvage of #55614 by @kartik-mem0 (mem0 maintainer). Adds a SelfHostedBackend
that talks to a self-hosted Mem0 Docker server over httpx (X-API-Key auth,
/search + /memories routes), gated behind `host`. Also folds in the mem0
research-team recall tuning that rides with it: rerank defaults to false across
all modes, the mem0_list tool is removed (5->4 tools), search guidance is
de-shouted, and self-hosted get_all reports the true stored total (#52921).
Supersedes the self-hosted portion of #52487 (@liuhao1024, first-submitted).
Closes#52478Fixes#52921
Fields can declare a longer 'info' text rendered as an (i) tooltip next to
the label in both the panel and the modal; honcho uses it to spell out the
session strategy, write frequency, and recall mode semantics. The modal
description claimed 'the active profile' without saying which — show the
active gateway profile name.
Providers with behavior beyond fields (validate a server, start a local
instance, link a CLI profile) previously had no mount besides forking the
panel. Let the schema declare actions and one generic endpoint run them:
ProviderAction on ProviderConfigSchema, POST
/api/memory/providers/{name}/actions/{action} dispatching to
ACTION_HANDLERS in the plugin's config_actions.py (path-loaded and
import-light, like the schema), profile-scoped and off the event loop.
Handlers get the submitted values dict, return a JSON-able result, and
raise ValueError for user-facing 400s. The panel renders declared actions
as generic buttons beside Save. No bundled provider declares actions yet.
The settings page follows the desktop's active-profile switcher, but the
provider config calls didn't: no profileScoped() on the client and no
profile param on the backend, so a multi-profile desktop edited the serving
process's config while every surrounding card showed the selected profile's.
Accept ?profile= on both endpoints and resolve inside _profile_scope (the
skills/toolsets contract), spread profileScoped() into the two client calls,
and key the schema cache on the resolved config_schema.py path instead of
the provider name — user-installed plugins are per-profile, so one profile's
lookup must never answer for another's.
Replace the hand-rolled ensurepip bootstrap (and five other one-off
pip-install code paths) with hermes_cli.tools_config._pip_install, which
prefers the bundled uv (fast, needs no pip in the venv), falls back to
python -m pip, and bootstraps pip via ensurepip only when missing.
Sites unified:
- hermes_cli/setup.py: _install_neutts_deps, _install_kittentts_deps,
modal SDK install, daytona SDK install
- hermes_cli/memory_setup.py: memory-plugin pip deps (previously dead-ended
when uv AND pip binaries were both absent)
- hermes_cli/dingtalk_auth.py: qrcode auto-install (previously invoked
'python -m uv' which is not how uv ships)
- agent/lsp/install.py: --target LSP server installs
- plugins/google_meet/cli.py, plugins/platforms/matrix/adapter.py,
plugins/platforms/google_chat/oauth.py, plugins/memory/honcho/cli.py
Tests updated to assert the ladder behavior (uv-first, pip fallback,
ensurepip bootstrap) instead of the removed bespoke branches.
ruff check --fix --select F541 . on current main. Pure prefix removals;
adjacent-string concatenations keep the f only on interpolating fragments.
No string content or live placeholder altered.
Multi-line comment blocks and JSDoc-style headers across the provider
config surface compress to one line each; the why lives in commit messages
and docstrings, not comment essays.
A syntax error in a provider's config_schema.py was cached as 'no schema'
until process restart, rendering a silent empty panel even after the file
was fixed. Cache only successful loads and genuine file-absence.
Each provider now declares its config surface in config_schema.py inside
its own plugin dir (plugins/memory/<name>/), loaded by file path like the
plugins themselves so plugin __init__ imports never reach the web server.
hermes_cli/memory_providers.py is gone; the shared field primitives and
loader live in plugins/memory/config_schema.py, and the schema tests move
to tests/plugins/memory/ alongside the other per-plugin suites.
The store-level search_facts() shared the same raw-MATCH bug class as
_fts_candidates (FTS5 AND-joins tokens, zeroing prose recall). Route it
through FactRetriever._sanitize_fts_query via a lazy import to keep the
store->retrieval layering acyclic. Also add cyb3rwr3n to release AUTHOR_MAP.
The FactRetriever's _fts_candidates passed the raw query string directly
to FTS5's MATCH operator. FTS5 defaults to AND-between-tokens, which
means any multi-word prose query like 'what happened with the deployment
rollback' required every single token to co-occur in a fact — dropping
recall to zero on the kind of queries agents actually issue via prefetch().
Fix: add _sanitize_fts_query() that:
- tokenizes the query and drops English stopwords
- strips FTS5 operator characters per token
- OR-joins the remaining content tokens as phrase literals
For pathological inputs (all stopwords, empty), falls back to the raw
query so the caller sees zero results instead of a SQL error.
This is a pure-retrieval-quality fix — the HRR + Jaccard reranking
stages still keep precision high. Ships with 10 tests covering the
sanitizer and retrieval integration.
The supermemory and mem0 memory providers shipped third-party SDKs
(supermemory / mem0ai) that are not core dependencies, but — unlike the
honcho and hindsight providers — they imported those SDKs directly with
no tools.lazy_deps.ensure() preflight and had no LAZY_DEPS allowlist
entry. On the published Docker image the agent venv is sealed
(HERMES_DISABLE_LAZY_INSTALLS=1) and lazy installs are redirected to a
writable durable target (HERMES_LAZY_INSTALL_TARGET). honcho/hindsight
route through ensure() and install fine there; supermemory/mem0 never
called it, so their SDK was never installed on a hosted instance and the
provider silently reported itself unavailable even with the API key set.
Fixes:
- Add memory.supermemory + memory.mem0 to the LAZY_DEPS allowlist
(tools/lazy_deps.py), pinned to current PyPI releases.
- Call ensure('memory.<x>', prompt=False) at each SDK-import chokepoint
(_SupermemoryClient.__init__; Mem0MemoryProvider._create_backend),
mirroring honcho's wrapped try/except shape.
- Drop the SDK-import gate from supermemory's is_available() — it was a
chicken-and-egg trap (provider never loaded on a sealed venv, so
ensure() never ran). Now key-presence only, like honcho/mem0.
- Add matching pyproject extras [supermemory]/[mem0]; update the
lazy-covered-extras contract test (excluded from [all] by policy).
Tests prove each path fails without the fix and the real sealed-venv
durable-target gate accepts both features.
HolographicMemoryProvider.shutdown() dropped its MemoryStore reference
without calling the existing MemoryStore.close(). Since the connection is
opened check_same_thread=False (one per session), its fd was released by
refcount/GC at a non-deterministic time on a non-deterministic thread,
churning a DB fd through the kernel free pool on every session teardown.
Call close() so the fd is released deterministically.
Reported by @alfranli123 (#44037), who pinpointed the exact code location.
Note: the report's TLS-fd-recycle corruption attribution could not be
reproduced from the code — dropping a sqlite connection flushes valid
SQLite pages via the VFS, never TLS framing, and the provider is at most a
releaser of DB fds, not a TLS-flushing socket owner. This change is correct
resource hygiene that removes per-session fd churn regardless.
Follow-up to #53791 addressing review feedback: the footgun checker treated
capture_output=/stdout=/stderr=/check_output as proof a subprocess can't pop a
Windows console. That invariant is false — stream redirection controls where a
child's output goes, not whether a console is allocated. From a console-less
parent (Desktop/Electron, pythonw.exe, detached gateway/cron) a console-subsystem
child still flashes a window even when fully captured.
- check-windows-footguns.py: capture/redirect/check_output is no longer a blanket
safe-pass. Added _WINDOWS_FLASHING_PROGRAMS (git/gh/npm/node/python/uv/ffmpeg/
docker/powershell/…); calls to those are flagged even when captured. Non-flashing
programs keep the capture exemption (no 271-site noise). _subprocess_compat.run/
popen calls are inherently safe (wrapper injects CREATE_NO_WINDOW).
- Routed the 35 genuine flashing git/gh/npm/uv/ffmpeg/docker spawns through the
_subprocess_compat.run/popen chokepoint (Brooklyn's wrapper from #53810) — the
durable fix, not per-site annotations. cmd.exe /c start stays # ok (intentional).
- Updated tests + CONTRIBUTING.md rule #17 to the corrected invariant.
* fix(windows): stop subprocess console-window popups + add CI guard
The single biggest source of Windows 'terminal popup' bug reports was bare
subprocess.run/Popen calls spawning a console window. The compat helpers
(windows_hide_flags / windows_detach_popen_kwargs) already existed but the
footgun checker had no rule to stop new bare calls from reintroducing the flash.
- scripts/check-windows-footguns.py: new AST-based rule flagging subprocess
calls that can create a new console — output-redirection-aware (capture/
redirect/check_output exempt) and POSIX-only-program-aware (launchctl/
systemctl/brew/etc. exempt). Comprehensive on real popups, no annotation
burden on calls that can't flash.
- Swept all genuine window-spawning sites through windows_hide_flags()/
windows_detach_popen_kwargs(); marked intentionally-visible launches
(editor/terminal/foreground re-exec) with '# windows-footgun: ok'.
- tests/scripts/test_windows_footgun_subprocess_rule.py: behavior-contract
tests + full-repo cleanliness invariant.
- CONTRIBUTING.md: documents the rule + the helper pattern.
* test: accept creationflags kwarg in psutil_android fake_subprocess_run
The Windows no-window sweep added creationflags=windows_hide_flags() to
install_psutil_android.py's subprocess.run call; the test's fake stub had a
fixed (cmd) signature and raised TypeError on the new kwarg.
Add post_setup() and get_status_config() to the Supermemory memory
provider so `hermes memory setup` and `hermes memory status` print a
one-line connection summary (container, profile fact count,
auto_recall/auto_capture). Point API-key onboarding at the Hermes
connect URL (app.supermemory.ai/integrations?connect=hermes).
Salvage of #52988. Two fixes folded in:
- Test isolation: the new probe/status tests mocked _SupermemoryClient
but not the __import__("supermemory") guard inside
_probe_supermemory_connection, so they passed only where the optional
supermemory package was installed and failed on a clean checkout / CI
(the PR shipped with red CI). Added _stub_supermemory_importable()
mirroring the existing test_is_available_false_when_import_missing
pattern; the suite now passes with supermemory absent.
- post_setup: `if api_key and api_key not in os.environ` checked whether
the key's *value* named an env var (always false in practice). Fixed to
compare the value: `os.environ.get("SUPERMEMORY_API_KEY") != api_key`.
Verified: 38/38 in test_supermemory_provider.py and the full
tests/plugins/memory/ suite green with supermemory not installed.
Closes#52988
Salvage of PR #48927 by @ehz0ah, which consolidates OpenViking recall
work from #41706 (@huangxun375-stack), #33260, #49975, and #32444.
Replaces stale background post-turn prefetch warming with synchronous
current-query recall. The old queue_prefetch warmed the PREVIOUS user
message while turn-start recall consumed the CURRENT one, so injected
context was always about the wrong topic.
Changes:
- prefetch() now does session-aware /api/v1/search/search with the
current query, falls back to /api/v1/search/find on failure
- Contract-safe payloads: limit, score_threshold, context_type,
session_id — no top_k, no search-body mode, no target_uri
- L2 content reads for items with level=2 or empty abstracts, capped
at full_read_limit (default 2)
- Local ranking (score + query-token overlap + leaf boost), dedup,
score threshold, and injected-char budget
- queue_prefetch() is now a no-op (background warming removed)
- Additive batched viking_read: uris param accepts up to 3 URIs
- Per-request timeout support on _VikingClient.get/post/delete
- Removes stale _prefetch_result/_prefetch_thread/_prefetch_generation
state and _invalidate_prefetch_state()
- Strengthened system_prompt_block guidance
Salvage follow-up fixes:
- Expose all 8 recall config knobs in get_config_schema() (PR #48927
had removed them; #41706 correctly exposed them). Env vars remain
as internal mechanism but are now visible in setup wizard.
- Lower default timeout 8s→4s, request_timeout 6s→3s, full_read_limit
3→2 to reduce per-turn blocking latency.

* test(honcho): isolate auth-method prompt from deployment-shape wizard tests
main's wizard suite scripts the cloud prompts without the OAuth auth-method step; auto-answer it in the shared helper so the answer lists stay shape-only.
* docs(honcho): document query-adaptive reasoning level (reasoningHeuristic)
README never mentioned reasoningHeuristic and listed reasoningLevelCap as an orphaned cap with the wrong default (— vs "high"). Add the query-adaptive scaling note + the reasoningHeuristic/reasoningLevelCap rows (grouped under Dialectic & Reasoning), matching the wording already on the hosted honcho.md page, and add a pointer from the memory-providers overview.
* fix(honcho): default the CLI peer prompt to the OAuth consent name
The CLI runs the grant with apply_config=False, so the peerName the user just entered at consent was dropped and the wizard's 'Your name' prompt fell back to $USER. Surface it as a transient OAuthCredential.consent_peer_name (set even when config isn't merged) and seed the prompt default from it.
* feat(honcho): split OAuth client_id by surface (cli=hermes-agent, desktop=hermes-desktop)
resolve_endpoints now picks the client_id from the initiating surface and
threads it through authorize -> token exchange -> persisted grant -> refresh,
so the CLI and desktop register as distinct OAuth clients. Surface-specific
env overrides (HONCHO_OAUTH_CLIENT_ID_CLI/_DESKTOP) win over the generic
HONCHO_OAUTH_CLIENT_ID, which still overrides every surface.
* feat(honcho): show OAuth vs API key in status; detect existing OAuth in setup
status now prints 'Auth: OAuth (clientId, token valid Xm/expired)' instead of
masking the OAuth access token as a generic API key; setup notes an existing
OAuth grant when re-run.
* docs(honcho): drop 'shared pool' wording from unified observation mode help
* fix(honcho): cross-process lock around OAuth refresh to prevent grant revocation
The in-process threading lock can't stop a sibling process (another profile or
the desktop app sharing honcho.json) from replaying the single-use refresh
token and tripping reuse-detection, which revokes the whole grant. Guard the
read-refresh-persist section with an OS file lock on <config>.lock so only one
process rotates at a time; the others re-read the freshly-persisted token.
Best-effort: platforms without flock degrade to in-process serialization.
* refactor(honcho): one OAuth client (hermes-agent) for all surfaces
Collapse the per-surface client_id split. CLI and desktop now use a single
client_id (hermes-agent); consent branding/UI still adapt via the source query
param. One grant identity means no clientId-vs-refresh-token desync that could
get the grant revoked. HONCHO_OAUTH_CLIENT_ID still overrides for self-hosting.
* fix(honcho): per-session resolves to session_id, never remapped by title
Reorder resolve_session_name so stable identifiers win over labels: gateway
per-chat key first, then the per-session session_id, then the cwd map / title.
A (possibly auto-generated) title can no longer remap a live per-session
conversation onto a second Honcho session mid-stream — fixes the desktop, which
is per-conversation via session_id. Consequence: a gateway's per-chat key now
also wins over a title (titles never remap a stable id).
Mirror built-in memory writes to external providers only after the native memory tool succeeds and is not staged for approval. Keep OpenViking's built-in memory mirroring add-only, since Hermes native memory entries do not yet have stable OpenViking file URIs for replace/remove.

* refactor: expand user paths, add collection recreation on dimension change for Qdrant
* fix(mem0): make MEM0_USER_ID override gateway-native ids and tag writes with channel
When MEM0_USER_ID was configured (env or mem0.json), the gateway-native id
from kwargs (Telegram numeric id, Discord snowflake, ...) still won, so the
same human ended up under different user_ids per channel and memories never
merged across CLI / Telegram / Slack / Discord. Mirrors openclaw's cfg.userId
pattern: configured override wins, gateway-native id is the fallback.
The legacy "hermes-user" placeholder default written by the setup wizard is
treated as unset to avoid silently bucketing every gateway user together.
Also tag every write with metadata.channel (cli/telegram/discord/...) so the
dashboard can offer per-channel filtered views without coupling identity to
the channel; document the read/write filter asymmetry as intentional
(reads scope to user_id only for cross-agent recall).

* fix(mem0): make get_config_schema() return unified schema with mode-aware required flag
Schema always includes api_key field so picker shows "API key / local" for

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* refactor: improve mem0 telemetry, add env var key and OSS mode detection
* chore: bump mem0ai lower bound to 2.0.4 (latest SDK release)
* refactor: set telemetry sample rate to 1.0 and update docs for opt‑out
* fix(mem0): resolve 15 correctness, thread-safety, and resource bugs
Thread safety:
- Protect circuit breaker counters with _breaker_lock (race between
prefetch/sync daemon threads and main thread)
- Wrap sync_turn thread creation in _sync_lock; skip if previous sync
is still alive after 5 s join to prevent duplicate memory ingestion
- Guard _schedule_flush timer creation under _queue_lock (TOCTOU race)
- Capture local `backend` reference in prefetch/sync closures so
shutdown() nulling self._backend cannot crash in-flight threads
Correctness:
- Fix bool("false")==True for rerank param; parse string values explicitly
- Guard page/top_k with max(1,...) and move int() inside try blocks
- Fix fact_count=0 always in OSS mode (Memory.add returns list, not dict)
- Fix prefetch() not clearing result when thread still alive after timeout
- Fix atexit.register accumulating on repeated initialize() calls
Backend / setup:
- Handle Qdrant named-vector collections in _recreate_collection_if_dims_changed
(vectors is a dict; .size access raised AttributeError, swallowed silently)
- Wrap QdrantClient and psycopg2 conn/cursor in try/finally to prevent leaks
- Resolve ollama_bin at top of _ensure_ollama; use it for ollama pull
- Fix embedder key lookup when LLM provider has no env_var (e.g. ollama)
Also: remove _telemetry_enabled cache (env var check is cheap), bump
required mem0ai to >=2.0.7, minor README wording fix.
* fix(mem0): fix brittle qdrant path test + add telemetry sample-rate docs
- Replace generator-throw lambda with a proper def in
test_qdrant_path_not_writable; use tmp_path instead of a hardcoded
/nonexistent path so the test is root-safe
- Add MEM0_TELEMETRY_SAMPLE_RATE to memory-providers.md (was only
in the plugin README, not the user-guide docs)
* revert: remove MEM0_TELEMETRY_SAMPLE_RATE from user-guide docs
* refactor: remove telemetry from mem0 plugin and update documentation
* fix(mem0): set stdin=DEVNULL on setup subprocess calls
The TUI stdin guard (scripts/check_subprocess_stdin.py) requires every
subprocess call in plugin code to set stdin= so it can't inherit the
gateway's JSON-RPC stdin fd. Muzzle the docker/ollama calls in the OSS
setup wizard with stdin=subprocess.DEVNULL (none need interactive input).
Also covers the docker-inspect call the linter's regex misses.

Addresses reviewer feedback on #13377:
1. Restore all stripped docstrings (_load_config, _is_breaker_open,
sync_turn, register, _get_client, _read_filters, _write_filters,
_unwrap_results, save_config) and section dividers
2. Revert api_key to required:true in schema — self-hosted Mem0 also
requires auth by default; validation in _get_client() handles the
either/or logic separately from the schema
3. Confirm secret:true remains on api_key (already correct)
The mem0 plugin previously hardcoded api.mem0.ai as the endpoint.
This adds a `host` config key and MEM0_HOST env var so users can
point the plugin at a self-hosted Mem0 instance.
Changes:
- _load_config(): read MEM0_HOST env var
- is_available(): accept host OR api_key (self-hosted may not need a real key)
- get_config_schema(): add host field
- initialize(): read host from config
- _get_client(): pass host kwarg to MemoryClient when set
- system_prompt_block(): show target (cloud vs URL)
- README: document self-hosted setup
On resource-contended hosts the embedded Hindsight daemon can exceed a
single 2s /health check; upstream then waits a grace window before
treating it as stale and killing+restarting it (hindsight-embed reads
HINDSIGHT_EMBED_PORT_HEALTH_GRACE_TIMEOUT, default 30s, into a
module-level constant at import time). Users on busy boxes had no
Hermes-side way to raise it short of hand-setting an env var.
Add a 'port_health_grace_timeout' config.json option to the Hindsight
plugin. When set, initialize() exports it to the process env BEFORE
daemon_embed_manager is imported (the import-time read is the contract).
setdefault() so an explicit operator env override always wins. Exposed
in 'hermes memory setup' for local_embedded mode.
Follow-up to #50308 / issue #13125 comment thread.
hermes backup only walks HERMES_HOME, so memory providers that keep
config/credentials in home-anchored dotdirs (honcho -> ~/.honcho,
hindsight -> ~/.hindsight, openviking -> ~/.openviking) lost that data
across a backup/import cycle — the peer IDs, session pairings, and API
keys never made it into the archive.
Add an optional MemoryProvider.backup_paths() hook (default []). The
active provider declares its external paths; backup resolves them from
config only (no init, no network), archives the ones under the home dir
into a reserved _external/ subtree encoded relative to home, and import
restores them to their original location with a home-anchored traversal
guard and 0600 on credential-shaped files. Paths outside home are
skipped as non-portable.
honcho, hindsight, and openviking override the hook. E2E-validated full
backup->import cycle plus 7 new tests.
PostgreSQL's initdb refuses to run as root, so the embedded Hindsight
daemon could never initialize its data directory under root. The
daemon-start thread would fail, retry, and loop forever — each cycle
reloading embedding models (~958MB RAM, ~33% CPU) with no user-visible
error, leaving Hermes sluggish on a common VPS/cloud root setup.
initialize() now detects root (os.geteuid() == 0) before spawning the
daemon thread, disables local_embedded mode, and surfaces a clear
warning to both the log and the terminal so the user knows to run as a
non-root user or switch to cloud / local_external mode.
Closes#13125.

The lazy_deps pin (memory.hindsight -> hindsight-client==0.6.1) was newer
than the plugin's stated floor (>=0.4.22). Align _MIN_CLIENT_VERSION,
the setup wizard dep string, plugin.yaml, and the README to 0.6.1 so the
floor check, auto-upgrade target, and runtime lazy-install all agree.
Also drops the redundant local _MIN_CLIENT_VERSION redefinition in
post_setup.
The batch tool_status values ('completed'/'error'/'pending') and the inbound
status alias sets were inline magic strings, duplicated across two checks in
_tool_result_status. Hoist them to module-level constants
(_TOOL_STATUS_* + _TOOL_STATUS_{ERROR,COMPLETED}_ALIASES) so the canonical
wire values and the alias->canonical mapping live in one place. Emitted
values are unchanged.
_messages_to_openviking_batch's pre-scan already parses and caches each
tool call's arguments into tool_calls_by_id. The pending-tool-call branch
re-parsed them via _tool_call_input(), a second parse and a second source
of truth. Reuse the cached tool_input when the id was cached (non-empty),
falling back to a parse only for the uncached empty-id case so arguments
are never dropped. No behavior change.
_OPENVIKING_RECALL_TOOL_NAMES hardcoded the three read-tool names as string
literals, which can silently desync from the *_SCHEMA["name"] constants on a
rename (the same drift the adjacent _CATEGORY_SUBDIR_MAP comment warns about).
Derive the set from SEARCH/READ/BROWSE_SCHEMA["name"] instead. Write tools
(viking_remember / viking_add_resource) remain intentionally excluded. Set
contents are unchanged.
Two follow-up fixes on top of the cherry-picked structured-sync work:
- _messages_to_openviking_batch only added a recall tool result's id to
skipped_tool_ids when the id was non-empty. An empty tool_call_id (which
the canonical transcript can carry; agent_runtime_helpers defaults it to
"") poisoned the skip set with "", silently dropping any *other* tool
result that also lacked an id. Move the recall-skip add inside the
existing `if tool_id:` guard. Adds a regression test (mutation-checked:
fails on pre-fix code, passes after).
- _sync_trace_enabled() open-coded the canonical truthy-env check; reuse
utils.env_var_enabled (byte-identical {1,true,yes,on} semantics).
Follow-up cleanup on the OpenViking setup path merged in #48262:
- _write_ovcli_config now uses utils.atomic_json_write(path, data, mode=0o600)
instead of the local _precreate_secret_file + write_text + chmod sequence.
The shared helper (already used by honcho/mem0/supermemory/hindsight) writes
via temp-file + fchmod(0600) + fsync + os.replace, so the ovcli.conf is
written atomically (no half-written secret file on crash) and with no
chmod-after-write TOCTOU window. _precreate_secret_file stays for the .env
writer path.
- Remove dead _DEFAULT_ACCOUNT/_DEFAULT_USER constants (0 references; the
empty->'default' tenant fallback lives in the _VikingClient constructor).
Tests: tests/plugins/memory/test_openviking_provider.py + test_memory_setup.py
+ openviking_plugin/test_openviking.py -> 130 passed; ruff clean.
Resolves conflicts from the OpenViking churn that merged after #32445 was
opened (#48042/#47662 session-switch + write hardening, #47311/#47973):
- plugins/memory/openviking/__init__.py: keep both __init__ field groups
(the PR's _runtime_start_* alongside main's _prefetch_threads/_shutting_down).
- tests/plugins/memory/test_openviking_provider.py: keep BOTH the PR's new
setup-validation tests and main's session-switch/concurrency tests (disjoint
additions to the same region).
Two fixes layered while reconciling (contributor work otherwise preserved):
- Restore the merged tenant-header contract (#22414/#21232). The PR had changed
_VikingClient defaults to '' and made empty account/user OMIT the tenant
headers; main's contract is that empty falls back to 'default' and the
X-OpenViking-Account/User headers are ALWAYS sent (ROOT API keys need them).
Reverted the constructor to 'account or os.environ.get(..., "default")' and
updated the two PR tests that asserted the omit-when-empty behavior.
- Close a secret-file TOCTOU in the setup writers. _write_env_vars and
_write_ovcli_config wrote the api_key/root_api_key file and chmod 0600
AFTERWARD, leaving a world-readable window on newly-created files. Added
_precreate_secret_file() to create with 0600 before any secret bytes land.
Follow-up hardening on @ehz0ah / @harshitAgr's session-switch work (#28296):
- on_session_switch no longer runs the old-session writer-drain + pending-token
GET + commit POST inline on the caller's command thread. /new, /branch,
/resume, /undo call it synchronously, so a slow drain (up to 10s) or wedged
commit blocked the user-facing command — the same hazard #41945 fixed for
end-of-turn sync. State now rotates synchronously (cheap) and the old-session
commit is offloaded to a daemon finalizer (generalized _finalize_session_async).
- Guard the (_session_id, _turn_count) pair with _session_state_lock: sync_turn
runs on the memory-manager executor thread while the session hooks run on the
command thread, so the snapshot+reset vs increment was a cross-thread race.
- _session_needs_commit checks the committed-session guard BEFORE the
turn_count>0 shortcut, closing a double-commit window when a racing sync_turn
re-increments after commit+reset.
- Add a _shutting_down flag so deferred finalizers stop POSTing against a
torn-down client; track all prefetch threads in a set so invalidate/shutdown
join every one, not just the latest slot.
Tests: regression for the non-blocking switch (asserts the caller returns while
a slow drain is parked off-thread) and the committed-guard ordering; updated the
deferred-commit test to the unified finalizer contract.
