Two safety nets for first-deploy on Blastware ACH machines that
have accumulated tens or hundreds of thousands of historical events
in the watch folder.
1. SFM_MAX_FORWARDS_PER_PASS (default 500, 0=unlimited)
---------------------------------------------------
Cap on the number of events forwarded per scan tick. At the
60-second default interval that's ~30K events/hour throughput —
the SFM server gets a steady drip instead of one giant burst.
Scan now sorts by mtime ascending so backfill advances
chronologically (oldest first) and successive scans always
make progress instead of re-considering the same N newest files.
Wired into:
- event_forwarder.find_pending_events / forward_pending
- series3_watcher.run_watcher loop
- config-template.ini
- settings_dialog SFM Forward tab (new "Max Events Per Pass"
spinbox, validated in _on_save)
2. event_forwarder.py --seed-state CLI
-----------------------------------
One-shot mode that walks the watch folder, sha256s every in-window
event binary, and marks them all as already-forwarded WITHOUT
POSTing anything. Run before flipping SFM_FORWARD_ENABLED=true
to skip the historical backfill entirely — the watcher then only
forwards events that appear AFTER the seed.
Usage:
python event_forwarder.py --seed-state \
--watch "C:\Blastware 10\Event\autocall home" \
--state "C:\...\sfm_forwarded.json" \
[--max-age-days 365]
7 new unit tests:
- max_per_pass cap enforcement (=N, =0 unlimited, oldest-first
ordering)
- seed-state mode (in-window seeding, max-age skip,
end-to-end skip-after-seed, idempotent re-runs)
README adds a "First-time deployment" section walking through both
options. Bumps to v1.5.2.
v1.5.0 shipped the forwarder module + INI keys but the settings
dialog wasn't extended, so the only way operators could enable
forwarding was hand-editing config.ini. This adds a sixth tab
("SFM Forward") with:
- Forward events to SFM checkbox
- SFM Server URL entry + Test button (GETs /health)
- Forward Interval (sec) spinbox
- Quiescence (sec) spinbox
- Missing-Report Grace spinbox
- HTTP Timeout spinbox
- State File entry + Browse...
Save-time guard: enabling the forwarder without a URL raises a
validation error rather than silently saving a non-functional
config.
Patch release — same on-disk INI schema, no config migration.
When SFM_FORWARD_ENABLED=true and SFM_URL is set, every Blastware
event binary in the ACH watch folder is forwarded to an SFM server's
/db/import/blastware_file endpoint as a multipart POST. The paired
<binary>.TXT ASCII report (which Blastware's ACH writes alongside
each event) is shipped in the same request, letting the SFM server
index the full per-channel stats — PPV, ZC Freq, Time of Peak, Peak
Acceleration / Displacement, Peak Vector Sum + time, sensor
self-check Pass/Fail per channel, and monitor-log timestamps —
without depending on the still-undecoded BW waveform body codec.
New module event_forwarder.py:
- is_event_binary() filename matcher (BW's <P><serial3><stem>.<ext>
scheme; rejects .MLG, .TXT, .log, .ini, .h5, etc.)
- ForwardState (.json file keyed by sha256 — idempotent across
restarts and auto-updates)
- find_pending_events() with quiescence + grace-period guards
- Hand-rolled multipart encoder (stdlib-only)
- forward_event_pair() / forward_pending() — POST loop with
structured per-event outcomes
Wired into series3_watcher.run_watcher() on its own cadence
(SFM_FORWARD_INTERVAL_SECONDS, default 60s) so it doesn't slow the
existing 5-min heartbeat scan.
Default-off: existing 1.4.x deployments keep their old behaviour
after auto-updating until an operator sets SFM_URL +
SFM_FORWARD_ENABLED=true and restarts.
17 unit tests in test_event_forwarder.py cover filename matching,
state idempotency, scan logic (quiescence, grace, max age,
already-forwarded, .TXT pairing), multipart byte shape, and an
end-to-end POST against a tiny stdlib http.server fake.
Bumps version 1.4.4 → 1.5.0 (minor — additive feature, no API break).
Requires SFM server v0.16+ for the paired-.TXT import endpoint.
Auto-updates now configurable (URL, source (gitea or private server), log activity for auto updates.
fix: Update now hardened to prevent installation of corrupt or incorrect .exe files. (security to be hardened in the future)
Feat: tray icon now shows API/watcher health rather than unit ages. unit submenu removed, now handled by recieving software.
Chore: remove old unneeded code from deprecated features (console colorization, Missing/pending age limits)
