- Changed glob → rglob in glean_dir so corpus directories with format
subfolders (journald/, docker/, etc.) are fully ingested
- Fixed gen_corpus.py docker SOURCE to emit "docker:<service>" prefix
so the pipeline correctly detects format as 'docker' not 'plaintext'
- 17/17 gen_corpus tests passing
Closes: #46
Adds scripts/gen_corpus.py that produces realistic-but-artificial log
files across all four supported formats (journald JSON, docker envelope,
qBittorrent hotio, EXT_DEVICE plaintext). Output feeds directly into
glean_corpus.py for demo environments and parser regression tests with
no production data required.
- Seed-based RNG with independent per-source sub-streams (same seed =
same sequence for each file regardless of source count changes)
- Controllable time range, event density, and error injection rate
- Severity distribution mirrors real infrastructure (70% INFO, ~6% ERROR,
~2% CRITICAL) with adjustable boost via --error-rate
- 17 tests covering output structure, reproducibility, format correctness,
parser round-trip, and CLI acceptance criteria
Also fixes a latent bug in app/glean/plaintext.py: ISO 8601 timestamps
were silently failing to parse because the T separator was normalised to
space in the input string but the strptime format string still contained T.
Fix: apply the same normalisation to the format before calling strptime.
Closes: #46
- Add app/db/ abstraction layer: Backend enum, DbConn wrapper,
dialect helper (q() for ? vs %s paramstyle), get_conn(), tenant_id()
- Auto-detect backend from DATABASE_URL; SQLite remains default when
unset — no config change for local deployments
- Add tenant_id column to all three logical DBs (main, context, incidents);
idempotent ALTER TABLE migration runs before schema scripts on existing DBs
- All INSERTs inject tenant_id; SELECTs use (tenant_id = ? OR tenant_id = '')
for backward compat with pre-namespacing rows
- Add docker-compose.yml with named volume turnstone_pgdata (survives rebuilds)
and optional external Postgres support via DATABASE_URL override
- Add scripts/migrate_sqlite_to_postgres.py — one-shot idempotent migration
for existing SQLite data; ON CONFLICT DO NOTHING for safe re-runs
- Fix SSH glean path in pipeline.py to use ensure_schema + get_conn
(was still using raw sqlite3.connect + old _SCHEMA without tenant_id)
- Fix FTS5 JOIN ambiguity: qualify repeat_count as f.repeat_count in search
- Update all tests to use ensure_*_schema fixtures; add row_factory where needed
- 394/394 tests passing
Closes: #42
Closes: #50
Adds a domain: field to the pattern taxonomy and surfaces per-domain
hit counts in diagnose summaries for faster triage.
Changes:
- LogPattern gains domain: str = "" (backward-compatible default)
- load_patterns() reads domain from YAML via p.get("domain", "")
- All 42 patterns in default.yaml annotated across 10 domains:
service_health | networking | auth | storage | memory |
kernel | power | web_proxy | media | gpu
- _pattern_domain dict built at startup from compiled patterns
- _domain_counts() helper: maps matched_patterns tags to domains,
counts hits per domain across a result set
- diagnose POST: summary includes by_domain: {domain: count}
- diagnose stream: summary SSE event includes by_domain when
pattern_domain is provided (passed from rest.py at startup)
- /api/search gains ?domain= filter: post-filters results to entries
whose matched_patterns include at least one tag in the given domain
Test fixtures: patch _pattern_domain={} and CONTEXT_DB_PATH in
test_blocklist_endpoints.py and test_glean_tautulli.py (worktree
has no data/ dir; same fix as feat/60-incidents-db).
372 tests passing.
Closes: #32
FTS5 bulk-insert write locks starved the incident API and bundle endpoints
during log bursts (sonarr/radarr, high-volume docker sources). Fix mirrors
the context_facts split (context -> turnstone-context.db):
- Add INCIDENTS_DB_PATH / TURNSTONE_INCIDENTS_DB env var in rest.py
- Add _INCIDENTS_SCHEMA, ensure_incidents_schema(), and
migrate_incidents_to_dedicated_db() in glean/pipeline.py
- Stub out incidents/received_bundles/sent_bundles in _SCHEMA (no-op
CREATE IF NOT EXISTS) so legacy single-file deployments still open
- Thread incidents_db_path through diagnose_stream -> run_pipeline ->
FalsePositiveSuppressor.suppress -> _fetch_resolved_incidents
- One-shot migration on startup: copy existing rows from main DB to
incidents DB via INSERT OR IGNORE (idempotent, safe to re-run)
- Fix test_blocklist_endpoints fixtures to patch CONTEXT_DB_PATH and
INCIDENTS_DB_PATH alongside DB_PATH (worktree has no data/ dir)
372 tests passing.
Closes: #60
Watcher, REST endpoints, services (search, incidents, blocklist),
MCP server, context retriever, embedder, glean_scheduler, and
doc_upload all used the default 5-second SQLite busy timeout.
During collect glean write phases, watcher flush threads were hitting
'database is locked' errors when the glean held the write lock longer
than 5 seconds.
All connections now use timeout=30.0, matching the pipeline fix
from commit 5a9281a. No logic changes.
pipeline.py:
- Add timeout=30.0 to all sqlite3.connect() calls (5 total).
Previously only ensure_context_schema() had it. The main glean
writers would fail immediately under lock contention from the live
watcher or concurrent manual glean runs.
glean_corpus.py:
- Add --force flag (passed through to glean_sources/glean_file/glean_dir).
Without it, unchanged-fingerprint files were silently skipped even
after pattern updates. Use after editing patterns/default.yaml.
patterns/default.yaml:
- Add 9 new patterns for Muninn / cluster-wide coverage:
vpn_tunnel_fail WireGuard/tunnel service failures
vpn_handshake WireGuard peer handshake events
dns_degraded systemd-resolved DNS fallback/degradation
nvidia_api_mismatch NVIDIA kernel module vs userspace mismatch
nvidia_xid NVIDIA Xid GPU hardware faults
nvidia_gpu_reset NVIDIA GPU reset / NVLink faults
acpi_error ACPI firmware _DSM evaluation failures
thermal_throttle CPU/GPU thermal throttling / RAPL unavailable
undervoltage PSU undervoltage / brownout events
- Sync from /devl/turnstone-cluster/patterns/default.yaml (authoritative
live copy updated first; repo copy was stale)
context_facts, context_documents, and context_chunks now live in
turnstone-context.db (sibling of turnstone.db). The glean scheduler
held write locks on the main DB long enough to cause 5-second timeout
failures on context fact inserts; separate files have independent WAL
write locks so they never contend.
Changes:
- pipeline.py: extract _CONTEXT_SCHEMA + ensure_context_schema()
- rest.py: CONTEXT_DB_PATH (TURNSTONE_CONTEXT_DB env var, defaults to
sibling file); init via ensure_context_schema(); all context routes
pass CONTEXT_DB_PATH; diagnose_stream receives context_db_path kwarg
- diagnose/__init__.py: diagnose_stream() accepts context_db_path
(falls back to db_path for backward compat); retrieve_context uses it
- store.py: sqlite3.connect() timeout=30.0 — Python driver retry loop
is independent of PRAGMA busy_timeout; needed for any remaining
contention during test or single-file deployments
Closes: #42
Closes turnstone#22.
## Transport layer (app/glean/ssh.py)
- SSHTransport context manager: key-only auth, paramiko backend
- SSHConnectionError / SSHCommandError exception hierarchy
- exec_stream() generator: yields stdout lines, raises SSHCommandError on
non-zero exit (isinstance(int) guard for test-mock safety)
- Command builders: _build_journald_command, _build_syslog_command,
_build_plaintext_command, _build_docker_command
- 18 unit tests in tests/test_glean_ssh.py
## Pipeline integration (app/glean/pipeline.py)
- _stream_and_write(): per-item error isolation — SSHCommandError skips
one glean item without aborting the rest of the host connection
- _glean_ssh_source(): one SSHTransport per host, dispatches all glean
items (journald/syslog/plaintext/docker); SSHConnectionError aborts host
- glean_sources(): splits local vs SSH sources; local → _glean_files();
SSH → _glean_ssh_source(); shared compiled patterns and DB connection
- glean_ssh_source(): public wrapper for REST use — manages DB connection,
pattern compilation, FTS rebuild lifecycle
- 15 integration tests in tests/test_glean_pipeline_ssh.py
- All 285 tests passing
## REST layer (app/rest.py)
- GET /api/sources/configured: reads sources.yaml and enriches with DB
stats; SSH sources appear before first glean (entry_count=0); sub-source
IDs (rack01/journald, rack01/docker/myapp) aggregated per host entry
- POST /api/sources/{id}/glean: detects transport:ssh and dispatches to
glean_ssh_source() wrapper; local sources unchanged
- Import: glean_ssh_source as _glean_ssh_source
## Frontend (web/src/views/SourcesView.vue)
- Fetches /api/sources/configured (primary) + /api/sources (DB-only) in
parallel; merges into unified SourceRow list
- SSH sources show: ssh badge (with user@host tooltip), glean-type pills
(journald/syslog/docker/etc.), host subtitle
- SSH sub-source IDs (rack01/journald) suppressed from the DB-only list
since they are covered by the parent SSH row
- DB-only sources (uploads) appear below configured sources with 'uploaded'
badge; reglean button disabled (not in sources.yaml)
- Delete zeroes out configured-source stats in-place rather than removing
the row (so the source remains visible for re-gleaning)
Adds SSH-based log collection from remote hosts via Paramiko.
One SSH connection per host, multiple log types per connection.
New files:
- app/glean/ssh.py: SSHTransport context manager + command builders
for journald, syslog, plaintext, and docker log types
- tests/test_glean_ssh.py: 18 tests for transport layer (all mocked)
- tests/test_glean_pipeline_ssh.py: 15 tests for pipeline integration
Pipeline changes (app/glean/pipeline.py):
- glean_sources() now splits sources into local-file and SSH categories
- SSH sources use transport: ssh + glean: list schema in sources.yaml
- _glean_ssh_source(): one SSHTransport per host, N commands per connection
- _stream_and_write(): SSHCommandError caught per-item so one bad
command does not abort the rest of the host's glean items
- SSHConnectionError skips the entire host with a warning log
SSH source schema (sources.yaml):
- id: rack01
transport: ssh
host: 192.168.1.10
user: admin
key_path: ~/.ssh/id_ed25519
glean:
- type: journald
args: [--since, 2 hours ago]
- type: syslog
path: /var/log/syslog
- type: plaintext
path: /var/log/app/error.log
- type: docker
containers: [myapp, nginx]
Key design decisions:
- Key-based auth only (no password prompts in daemon context)
- exit-status check fires after all stdout lines yielded; callers
drain the iterator to trigger it
- Local file sources path unchanged; SSH sources co-exist in same yaml
- Docker multi-container: one exec_stream call per container,
source_id scoped as host_id/type/container_name
Remaining for #22: REST endpoint, SourcesView UI, sources.yaml docs.
285 → 285 tests passing (33 new SSH tests).
