fix: remove networkidle waits and timeout bumps that regressed #248 speed

PR #248 specifically removed networkidle waits and kept tight timeouts for speed in an SPA where they're unnecessary. This commit removes the networkidle and timeout increases added in the previous commit while keeping the actual flakiness fixes: Kept: - Deterministic seed data script (tools/seed-test-data.js) - Retry logic (1 retry per test) - Fresh navigation for groupByHash test - Compare page explicit waitForFunction/waitForSelector waits - Observers page waitForFunction for table rows Reverted: - Default timeout 10s→15s (back to 10s) - All added networkidle waits (6 instances) - Map marker timeout 3s→8s (back to 3s) - Node detail timeout bumps - Nodes page timeout bumps Principle: fix flakiness with deterministic data and targeted waits, not with slower timeouts and networkidle.
fix: make E2E Playwright tests more resilient to flaky CI

Kpa-clawbot	0c1c0b4849	fix: remove networkidle waits and timeout bumps that regressed #248 speed PR #248 specifically removed networkidle waits and kept tight timeouts for speed in an SPA where they're unnecessary. This commit removes the networkidle and timeout increases added in the previous commit while keeping the actual flakiness fixes: Kept: - Deterministic seed data script (tools/seed-test-data.js) - Retry logic (1 retry per test) - Fresh navigation for groupByHash test - Compare page explicit waitForFunction/waitForSelector waits - Observers page waitForFunction for table rows Reverted: - Default timeout 10s→15s (back to 10s) - All added networkidle waits (6 instances) - Map marker timeout 3s→8s (back to 3s) - Node detail timeout bumps - Nodes page timeout bumps Principle: fix flakiness with deterministic data and targeted waits, not with slower timeouts and networkidle.	2026-03-29 16:57:52 +00:00
Kpa-clawbot	b47571c7f0	fix: make E2E Playwright tests more resilient to flaky CI Key changes: - Add retry logic (1 retry) to test runner for transient failures - Increase default timeout from 10s to 15s for slow CI runners - Add networkidle waits after navigation on nodes, map, packets, channels, and observers pages - Add explicit waitForSelector timeouts on node detail, map markers, and observer table rows - Fresh page navigation for groupByHash test to avoid stale state - Wait for compare results to render before asserting on cards - Increase map marker wait timeout from 3s to 8s - Add seed-test-data.js to CI pipeline to ensure deterministic test data exists (nodes with locations, packets, channels, observers) - Seed data creates 8 nodes, 3 observers, channel messages, and various packet types for full page coverage	2026-03-29 16:53:12 +00:00
Kpa-clawbot	5bb9bc146e	docs: remove letsmesh.net reference from README (#233 ) * docs: remove letsmesh.net reference from README Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> * ci: remove paths-ignore from pull_request trigger PR #233 only touches .md files, which were excluded by paths-ignore, causing CI to be skipped entirely. Remove paths-ignore from the pull_request trigger so all PRs get validated. Keep paths-ignore on push to avoid unnecessary deploys for docs-only changes to master. * ci: skip heavy CI jobs for docs-only PRs Instead of using paths-ignore (which skips the entire workflow and blocks required status checks), detect docs-only changes at the start of each job and skip heavy steps while still reporting success. This allows doc-only PRs to merge without waiting for Go builds, Node.js tests, or Playwright E2E runs. Reverts the approach from `7546ece` (removing paths-ignore entirely) in favor of a proper conditional skip within the jobs themselves. * fix: update engine tests to match engine-badge HTML format Tests expected [go]/[node] text but formatVersionBadge now renders <span class="engine-badge">go</span>. Updated 6 assertions to check for engine-badge class and engine name in HTML output. --------- Co-authored-by: Kpa-clawbot <259247574+Kpa-clawbot@users.noreply.github.com> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> Co-authored-by: Kpa-clawbot <kpabap+clawdbot@gmail.com> Co-authored-by: you <you@example.com>	2026-03-29 16:25:51 +00:00
you	12d1174e39	perf: speed up frontend coverage tests (~3x faster) Three optimizations to the CI frontend test pipeline: 1. Run E2E tests and coverage collection concurrently - Previously sequential (E2E ~1.5min, then coverage ~5.75min) - Now both run in parallel against the same instrumented server - Expected savings: ~5 min (coverage runs alongside E2E instead of after) 2. Replace networkidle with domcontentloaded in coverage collector - SPA uses hash routing — networkidle waits 500ms for network silence on every navigation, adding ~10-15s of dead time across 23 navigations - domcontentloaded fires immediately once HTML is parsed; JS initializes the route handler synchronously - For in-page hash changes, use 200ms setTimeout instead of waitForLoadState (which would never re-fire for same-document nav) 3. Extract coverage from E2E tests too - E2E tests already exercise the app against the instrumented server - Now writes window.__coverage__ to .nyc_output/e2e-coverage.json - nyc merges both coverage files for higher total coverage Also: - Split Playwright install into browser + deps steps (deps skip if present) - Replace sleep 5 with health-check poll in quick E2E path	2026-03-29 09:12:23 -07:00
you	3bbd986d41	fix: add sleep before poller data insert to prevent race condition in tests The poller's Start() calls GetMaxTransmissionID() to initialize its cursor. When the test goroutine inserts data between go poller.Start() and the actual GetMaxTransmissionID() call, the poller's cursor skips past the test data and never broadcasts it, causing a timeout. Adding a 100ms sleep after go poller.Start() ensures the poller has initialized its cursors before the test inserts new data.	2026-03-29 08:32:37 -07:00
you	712fa15a8c	fix: force single SQLite connection in test DBs to prevent in-memory table visibility issues SQLite :memory: databases create separate databases per connection. When the connection pool opens multiple connections (e.g. poller goroutine vs main test goroutine), tables created on one connection are invisible to others. Setting MaxOpenConns(1) ensures all queries use the same in-memory database, fixing TestPollerBroadcastsMultipleObservations.	2026-03-29 08:32:37 -07:00
Kpa-clawbot	ab03b142f5	fix: per-observation WS broadcast for live view starburst — fixes #237 IngestNewFromDB now broadcasts one message per observation (not per transmission).

you	def95aae64	fix: align packet decoder with MeshCore firmware spec Compared decoder.js against the MeshCore firmware source (Dispatcher.cpp, Packet.h, Mesh.cpp, AdvertDataHelpers.h) and fixed all mismatches: 1. Field order: transport codes now parsed BEFORE path_length byte, matching the spec: [header][transport_codes?][path_length][path][payload] 2. ACK payload: was incorrectly decoded as dest(1)+src(1)+ackHash(4). Firmware shows ACK is just checksum(4) — no dest/src hashes. 3. TRACE payload: was incorrectly decoded as flags(1)+tag(4)+dest(6)+src(1). Firmware shows tag(4)+authCode(4)+flags(1)+pathData. 4. ADVERT appdata: added missing feature1 (0x20 flag) and feature2 (0x40 flag) parsing — 2-byte fields between location and name. 5. Transport code field naming: renamed nextHop/lastHop to code1/code2 to match spec terminology (transport_code_1/transport_code_2). 6. Fixed incorrect field size labels in packets.js hex breakdown: dest/src are 1 byte, MAC is 2 bytes (not 6B/6B/4B). 7. Fixed ANON_REQ/PATH comment typos (dest was listed as 6 bytes, MAC as 4 bytes — both wrong, code was already correct). All 329 tests pass (66 decoder + 263 spec/golden).	2026-03-29 08:32:16 -07:00

you	8e66c68d6f	fix: cache hit rate excludes stale hits + debounce bulk-health invalidation Two cache bugs fixed: 1. Hit rate formula excluded stale hits — reported rate was artificially low because stale-while-revalidate responses (which ARE cache hits from the caller's perspective) were not counted. Changed formula from hits/(hits+misses) to (hits+staleHits)/(hits+staleHits+misses). 2. Bulk-health cache invalidated on every advert packet — in a mesh with dozens of nodes advertising every few seconds, this caused the expensive bulk-health query to be recomputed on nearly every request, defeating the cache entirely. Switched to 30s debounced invalidation via debouncedInvalidateBulkHealth(). Added regression test for hit rate formula in test-server-routes.js.	2026-03-29 07:51:08 -07:00
you	37396823ad	fix: align Go packet decoder with MeshCore firmware spec Match the C++ firmware wire format (Packet::writeTo/readFrom): 1. Field order: transport codes are parsed BEFORE path_length byte, matching firmware's header → transport_codes → path_len → path → payload 2. ACK payload: just 4-byte CRC checksum, not dest+src+ackHash. Firmware createAck() writes only ack_crc (4 bytes). 3. TRACE payload: tag(4) + authCode(4) + flags(1) + pathData, matching firmware createTrace() and onRecvPacket() TRACE handler. 4. ADVERT features: parse feat1 (0x20) and feat2 (0x40) optional 2-byte fields between location and name, matching AdvertDataBuilder and AdvertDataParser in the firmware. 5. Transport code naming: code1/code2 instead of nextHop/lastHop, matching firmware's transport_codes[0]/transport_codes[1] naming. Fixes applied to both cmd/ingestor/decoder.go and cmd/server/decoder.go. Tests updated to match new behavior.	2026-03-29 07:50:51 -07:00
you	074f3d3760	ci: cancel workflow run immediately when any test job fails When go-test or node-test fails, the workflow run is now cancelled via the GitHub API so the sibling job doesn't sit queued/running.
