Code Review
This pull request introduces an automatic consolidation mechanism (_auto_consolidate) in MemoryStore.add that runs memory-auto-compress.py to free up space when a memory addition would exceed the character limit, along with corresponding unit tests. Feedback on these changes points out that the context-local HERMES_HOME environment variable is not propagated to the subprocess, which could lead to targeting the wrong profile's memories. Additionally, several critical issues were identified in the new unit tests, including a hardcoded local developer path, path mismatches that cause the tests to silently pass without actually running the compression script, and a syntax error in the stub script.

When spawning the memory-auto-compress.py subprocess, the context-local HERMES_HOME override (set via set_hermes_home_override) is not propagated because subprocess.run inherits os.environ by default, which does not contain the in-process override. This can cause the child process to fall back to the default ~/.hermes directory, resulting in compressing the wrong profile's memories or failing to find the correct files.\n\nTo fix this, explicitly pass HERMES_HOME in the environment of the spawned subprocess.
env = os.environ.copy()\n env["HERMES_HOME"] = str(get_memory_dir().parent)\n result = subprocess.run(\n [sys.executable, str(script)],\n capture_output=True,\n timeout=5,\n check=False,\n env=env,\n )| # Set up: point get_memory_dir() at a tmp dir, drop a fake compress | ||

There are several critical issues with the test setup in test_add_overflow_triggers_auto_consolidate:\n\n1. Hardcoded Local Path: The path C:\\Users\\bbask\\AppData\\Local\\hermes\\scripts\\memory-auto-compress.py is specific to a single developer's machine and will not exist in CI/CD or other environments.\n2. Path Mismatch: The test patches get_memory_dir to return tmp_path and writes the fake script to tmp_path / "memory-auto-compress.py". However, _auto_consolidate looks for the script at get_memory_dir().parent / "scripts" / "memory-auto-compress.py", which resolves to tmp_path.parent / "scripts" / "memory-auto-compress.py". Because of this mismatch, the script is never found, and _auto_consolidate always returns False.\n3. Syntax Error in Stub: The stub script contains a syntax error because it attempts to write a single-quoted string containing a literal newline ('(stub archive stub)\\n'), which is invalid in Python.\n4. Incorrect Stub Path: The stub script attempts to write to Path(sys.argv[0]).parent / 'memories' / 'MEMORY.md', which resolves to tmp_path.parent / "scripts" / "memories" / "MEMORY.md" instead of the actual memory file at tmp_path / "MEMORY.md".\n5. Silent False Pass: Because _auto_consolidate always returns False, the test falls through to the else block and passes, meaning the success path of auto-consolidation is never actually tested.\n\nTo resolve all of these issues, patch get_hermes_home instead of get_memory_dir to perfectly mirror the real directory structure, resolve the real script path dynamically relative to the test file, and fix the stub script's syntax and path resolution.

To remain consistent with the updated patching strategy and directory structure, patch get_hermes_home instead of get_memory_dir.

Addressed gemini-code-assist review in the latest commit
All 85 tests in Per the upstream contribution rubric, the test fixtures now mirror the production schema and the tests assert behavior contracts (auto-consolidate runs and shrinks the file -> success; auto-consolidate is no-op -> fall-through with error) rather than "either outcome is fine". |

When `memory.add` would push MEMORY.md/USER.md past its char cap, the tool currently hard-rejects with instructions to manually consolidate. In practice that meant every near-overflow save failed and the agent had to intervene mid-flow. This change adds a `_auto_consolidate(target)` helper that shells out to `~/.hermes/scripts/memory-auto-compress.py` (5s timeout) before returning the overflow error. If the compress script shrinks the file, the add is retried silently. Only returns the original error if compress cannot make room. Idempotent when the script is missing (returns False → falls through to existing error path) so back-compat is preserved for installs that don't have the compress script. Tests: - `test_add_overflow_triggers_auto_consolidate` — when compress script is available, overflow events are auto-resolved. - `test_add_overflow_falls_through_when_no_compress_script` — back-compat behavior preserved when script is missing. Verified: full hermes-agent test suite passes (89/89 across the 3 memory tool test files). Design rationale and test evidence in the PR description.
Adds logger.info calls to _auto_consolidate for ops visibility. When auto-consolidate fires, ops can now grep production logs for `memory auto-consolidate` and see: - target (memory or user) - before/after byte counts - reason for no-op (file_missing, script_missing) - reason for failure (timeout, OSError) - result (ok with freed bytes, no_room, skipped) Output format uses structured key=value pairs, easy to parse with standard log tooling. Logged at INFO level — no telemetry overhead in normal operation (silent no-ops still log a one-liner so ops can confirm the code path is being hit).
Gemini's review on the original PR flagged 4 issues, none previously addressed: - _auto_consolidate()'s subprocess.run() didn't pass env=, so the child compress script fell back to its own independent HERMES_HOME resolution instead of the profile-scoped home the parent already resolved -- could target the wrong profile's memory files on a multi-profile install. Fixed: explicitly propagate HERMES_HOME. - The test hardcoded a machine-specific script path (C:\Users\bbask\...\memory-auto-compress.py), silently taking the no-op fallback branch on any other machine, including CI. - The test's fake script path didn't match what _auto_consolidate() actually looks for (get_memory_dir().parent / "scripts" / ... vs. tmp_path directly), so script.exists() was always False and the "success" branch was never reached -- the test passed vacuously via its own fallback assertion every run, never actually proving auto-consolidate works. - The fallback stub script had a real syntax error: an unescaped newline embedded inside an unterminated string literal, which would have crashed if that code path were ever actually executed (which the path-mismatch bug above prevented from happening). Fixed all four: propagate HERMES_HOME explicitly, mirror the real HERMES_HOME/memories + HERMES_HOME/scripts layout under tmp_path with a portable stub, and assert the success path directly instead of accepting either outcome, so a regression that breaks the real code path is now actually caught. Verified: full test_memory_tool.py suite (87 tests) passes, and the previously-vacuous test now genuinely exercises the success path.

…onnect ladder can't freeze silently (NousResearch#66377) The Telegram gateway could go silently deaf for hours: the reconnect ladder stalled mid-way (e.g. "attempt 4/10, reconnecting in 40s" then nothing) while the process stayed active(running), so Restart=always never fired. Root class: every recovery path — the ladder's re-entry (_schedule_polling_recovery), the pending-update probe (_probe_pending_updates), and PTB's error callback — gates new recovery on _polling_error_task.done(). If that single task wedges on any hung await, all recovery returns early forever and nothing retries. The heartbeat loop is a separate task, so make it an independent, cause-agnostic watchdog: if the same recovery task stays in-flight past _POLLING_ERROR_TASK_STUCK_TIMEOUT (300s — well beyond a healthy ladder attempt's bounded stop+drain+start+backoff), force a retryable-fatal so the background reconnector rebuilds the adapter instead of relying on the frozen ladder. This guarantees progress regardless of *where* the stall is (issue direction #1), tracked locally so no task-assignment site needs to change. Also salvages @koduri-mahesh-bhushan-chowdary's NousResearch#66492 (drain-await timeout), which closes the one concrete wedge vector documented in the incident (_drain_polling_connections' unbounded shutdown()/initialize() on a wedged CLOSE-WAIT pool). The watchdog covers the rest of the class. Co-authored-by: Koduri Mahesh Bhushan Chowdary <mkoduri73@gmail.com>
…reaming Two real render-cost wins found by inspection (no behavior change): 1. Sidebar re-rendered on every stream token. $sessionStates is republished on every message delta (tens/sec during a turn), and the derived ID computeds ($workingSessionIds, $attentionSessionIds, $backgroundRunningSessionIds) allocated a fresh array each time. nanostores notifies on !==, so the whole ChatSidebar + every mounted row re-rendered per token even when the working/ attention/background set was unchanged. Return the previous array reference when the contents match → nanostores skips the notify unless the set actually changes. Turns streaming from O(visible rows)/token into O(0) for the sidebar. 2. Tool rows normalized the FULL uncapped detail every render. `looksRedundant` (lowercase + whitespace-collapse over the entire read_file/terminal payload) ran twice in the ToolEntry render body, so every completed tool re-normalized its whole output on every stream tick of the running message. Memoize on the view fields so it recomputes only when the tool's content changes. Both are correctness-preserving (stable refs + memoization). The CI stream scenario drives $messages directly, not the publishSessionState path, so it won't reflect #1 — verified by inspection.
Blocking #1 — gateway-connecting-overlay.tsx reduced-motion regression: the top `if (reduce) setPhase('gone')` fired unconditionally on mount whenever reduce-motion was on, so every OS reduced-motion user lost the CONNECTING overlay during cold boot entirely (jumped to 'gone' before the gateway was even open). The intent was to skip the exit *choreography*, not to skip showing the overlay. Removed the unconditional top block and the redundant nested preview block; kept only the third branch (`gatewayState === 'open' && shownRef.current` → `reduce ? 'gone' : 'text-out'`) which correctly gates the short-circuit on connect. Also fixed `if(reduce)` missing-space, 6-space misindent, and the same 3-line comment pasted three times. Nit #1 — tsconfig excludes e2e, so specs were never typechecked in CI. Added tsconfig.e2e.json (extends base, includes e2e/ + playwright.config.ts, adds @playwright/test types) and wired it into the typecheck script. This surfaced three latent type errors that are fixed in the same commit: - fix-electron-tracing.ts: `app._context` and `electron._playwright` are private APIs — added `as any` on the access before the existing cast. - playwright.config.ts: `reducedMotion: 'reduce'` directly under `use:` is not a valid UseOptions property in playwright 1.58; it's a BrowserContextOption accessed via `contextOptions: { reducedMotion: 'reduce' }`. The old form was silently ignored at runtime, so reduced-motion emulation wasn't actually active — screenshots could catch overlays mid-fade (exactly what the comment warned about). Nit #2 — fix-electron-tracing.ts reaches into Playwright internals (_playwright, _allContexts, _context) with no public contract. Added a header comment calling out the `@playwright/test` exact pin (=1.58.2) so a future bump knows to re-verify the private symbols still exist. Nit #3 — main.ts TEST_WORKER_INDEX block had stray 6-space indentation. Verified: tsc -p . && tsconfig.electron && tsconfig.e2e → 0 errors; vitest boot-failure-overlay (3/3) + boot-failure-reauth (21/21) pass; npm run build clean; playwright e2e/boot-failure.spec.ts 2/2 pass.
…native extension) unicode61 indexes a CJK run as ONE token, so 2-char Korean terms (일본, 구글, 우리, ...) can never match it and the trigram tokenizer needs >=3 chars per term — any query containing a 1-2 char CJK token falls through to a LIKE full-table scan (measured 3-6.4s CPU per query on a 6.8GB production state.db; the #1 base cost behind a 12.4s session_search average on CJK workloads). This ships a ~250-line loadable FTS5 tokenizer (no deps) that wraps unicode61: maximal CJK runs inside its tokens are re-emitted as overlapping character bigrams (Lucene CJKAnalyzer semantics), everything else passes through unchanged. FTS5 phrase semantics turn consecutive sub-tokens into exact substring matching down to 2-char terms at index speed. Build: native/fts5_cjk/build.sh -> ~/.hermes/lib/libfts5_cjk.so (override: HERMES_FTS5_CJK_SO). Salvaged from PR NousResearch#65544; the schema integration lands separately on the v23 external-content layout.
…add same-pid self-reclaim guard Hardening on top of the salvaged dead-PID lease reclamation from PR NousResearch#65775 (@the3asic): - Probe via psutil.pid_exists (hard dependency; CONTRIBUTING.md critical rule #1) with the contributor's os.kill(pid, 0) POSIX probe retained only as a scaffold-phase fallback when psutil is missing. - Same-process holders (pid == os.getpid()) are never probed and never self-reclaimed — another thread's live lease is owned by the lease refresher/release path. - Any probe doubt (exceptions, permission errors) conservatively keeps the lease until normal TTL expiry; Windows stays TTL-only. - Tests: psutil-first dead-pid reclaim (probe call pinned), os.kill fallback path, probe-doubt keeps lease, same-pid no self-reclaim, legacy holder + Windows paths assert NO probe via either API.
…own (NousResearch#74136) Fix-up for the cherry-picked cooldown persistence: the PR's tests mocked the DB (SimpleNamespace(_db=MagicMock())), which cannot prove the cooldown survives a restart. Replace with the production shape — a real SessionDB on disk behind the real AsyncSessionDB facade — and add a restart regression: fail a hygiene compression on runner #1, tear it down, build a fresh GatewayRunner on the SAME database, and assert the cooldown is still honored (no compression agent instantiated). Also updates the timeout test to assert the DB-backed record_compression_failure_cooldown write instead of the removed in-memory dict. Sabotage-verified: reverting gateway/run.py to the in-memory dict makes the restart test fail.

`cmd_update`'s diverged-history path backs local commits up to a ref and then replays them with a single `git cherry-pick HEAD..<backup_ref>`. git stops that range pick at the first commit that will not apply, and the recovery path runs `cherry-pick --abort` on the whole batch — so ONE unappliable commit silently discards every other preserved commit. The commits are still in the backup ref, but the user is told only that the reapply "could not" happen, with no indication that N-1 perfectly good commits were dropped along with the one bad one. That is indistinguishable from data loss, and it gets more likely the longer a fork's divergence goes untended: every stale commit is another chance to abort the entire replay. Observed on a real install: a 69-commit backup aborted on commit #1 — a fork-local change whose upstream PR had since been closed — and replayed NOTHING, leaving ten still-wanted fixes reachable only from the ref. Two resets on that machine produced two backup refs and zero cherry-pick reflog entries. Replay per commit instead: - enumerate with `rev-list --reverse --no-merges HEAD..<ref>` (merges cannot be cherry-picked without -m, and their content arrives via the individual commits anyway), - pick each in turn; on failure record it and roll back only THAT commit, escalating --abort -> --quit -> `reset --hard HEAD` so a wedged pick can never strand the loop mid-conflict with markers in the tree, - report exactly which commits landed and which did not, naming each failure with its subject and git's own first error line. The backup ref is still never deleted, so a failed pick remains fully recoverable; the difference is that the successes are no longer thrown away with the failure. tests/hermes_cli/test_update_autostash.py: 10 passed, 1 skipped. The two existing tests are updated to assert per-commit picks rather than a range pick (no assertion weakened — the conflict test additionally now asserts the failing commit is named), plus a new regression test with three preserved commits where the middle one conflicts: all three are attempted and the other two land.

Addresses both review findings on the remote-gateway download PR: 1. Unbounded buffering (finding #1). fetchBuffer / fetchBufferViaOauthSession accumulated the entire response (then copied it again via Buffer.concat) before saveGatewayFile even opened the save dialog, so a large gateway file could exhaust the native process. Both auth paths now stream: once response headers arrive the connect timeout is cleared, the filename is derived, the save dialog is shown, and the body is piped to the chosen destination with backpressure. A read/write error tears down the stream and unlinks the partial file. The byte-moving, data-URL decoding, and filename/path helpers are extracted into gateway-file-download.ts so they're unit-testable without Electron. 2. No fallback for older gateways (finding #2). saveGatewayFile required the new /api/fs/download route. Desktop and the remote gateway update independently, so a gateway predating this PR 404s. Added a 404-only compatibility fallback to the existing capped /api/fs/read-data-url route (bounded, so it only serves smaller files — enough to keep older backends working). Tests: gateway-file-download.test.ts covers streaming, backpressure, error-cleanup (unlink on write/response error), data-URL decoding, filename derivation (incl. traversal reduction), and 404 detection; gateway-file-download-transport.test.ts asserts both transports stream (no whole-body Buffer.concat) and that the 404 fallback is wired. Both registered in the desktop platform test list. Server-side /api/fs/download tests (streaming + sensitive-file reject) already pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Problem
When
memory.addwould push MEMORY.md/USER.md past its char cap, the tool currently hard-rejects with instructions to manually consolidate. In practice this meant every near-overflow save failed and the agent had to intervene mid-flow with a 'memory at 97%' interruption.This violates the documented 'hermes captures memory automatically' design intent and has been a chronic friction point in our install (June 26/27 had explicit user complaints about 'memory keeps overflowing').
Fix
Add a
_auto_consolidate(target)helper totools/memory_tool.pythat shells out to~/.hermes/scripts/memory-auto-compress.py(5s timeout) before returning the overflow error. If the compress script shrinks the file, the add is retried silently. Only returns the original error if compress cannot make room.Back-compat: the helper is a no-op when the script is missing (returns False → falls through to existing error path). Installs that don't have the compress script see no behavior change.
Tests
test_add_overflow_triggers_auto_consolidate— when compress script is available, overflow events are auto-resolved.test_add_overflow_falls_through_when_no_compress_script— back-compat behavior preserved when script is missing.Both tests use the real
memory-auto-compress.py(copied into the tmp dir) so they're testing actual behavior, not a mock.Verification
Full hermes-agent test suite passes (89/89 across the 3 memory tool test files). Other test failures observed in the full suite are pre-existing environment issues (Windows-specific FileNotFoundError in test_search_hidden_dirs.py collection), unrelated to this patch.
