iopsystems/rezolus v5.13.0

on GitHub

Added

• BPF: blockio_requests sampler now also reports per-op error counts
  (with a coarse class derived from blk_status_t — io / timeout /
  nospc / target / protection / unsupported / other) and requeue
  counts, exposed as blockio_errors and blockio_requeues. The new
  counters are folded into the existing sampler so the
  block_rq_complete hot path stays single-attach. (#873)
• Dashboard: new "Exceptions" section consolidating cross-subsystem
  fault signals — network drops & transmit faults, TCP retransmits,
  AWS ENA allowance hits, CFS bandwidth throttling, and the new block
  IO errors / requeues. (#873)
• Viewer (static site): ?capture=alias=URL now accepts absolute
  http(s) URLs in addition to bundled-demo paths, with comma-separated
  pairs routing straight to A/B compare mode. Landing page split into
  Demos / Explore sections with a "Load from URL" textarea. (#886)
• Viewer (server): opt-in URL-fetch proxy via --proxy-allow <HOST_PATTERN> (repeatable, shell-style with * matching a single
  DNS label) plus a --proxy-allow-any escape hatch. Adds
  POST /api/v1/load_url so the browser can hand off remote parquet
  captures the server fetches and ingests on its behalf; the landing
  page greys out URL loading when no allowlist is configured and
  prints a warning at startup in any-mode. (#888)
• Viewer: tri-state urlLoading (disabled / proxy / direct)
  exposed via /api/v1/mode so the static-site and binary frontends
  surface accurate hints about how URL fetches will be performed.
  (#888)
• CI: release builds publish a self-contained
  rezolus-viewer-vX.Y.Z.tar.gz bundle (WASM + frontend assets, demo
  parquets excluded, symlinks dereferenced) alongside the deb/rpm
  packages. (#885)
• Tests: end-to-end tests/viewer_smoke.sh exercising rezolus view
  in upload-only, file, A/B, and proxy modes against checked-in demo
  parquets, plus a companion viewer-smoke skill for triage. (#893)
• Docs: docs/principles.md capturing the design rules Rezolus
  commits to for BPF samplers (always-on production use, in-kernel
  aggregation read via mmap, H2 histograms, etc.) and the operational
  checklist for reviewing or writing a sampler. (#887)

Changed

• Viewer: split the 2.6k-line src/viewer/mod.rs into focused
  submodules (state.rs, metadata.rs, routes.rs, actions.rs).
  No behavior change. (#892)
• Viewer: multi-line chart palette swapped to d3 schemeCategory10 /
  schemeCategory20 for stronger discriminability on dark
  backgrounds; muted brown / gray pairs dropped from the cgroup color
  rotation. Per-chart description text now renders as a sibling block
  above the chart card. (#873)
• Bumped direct deps arrow / parquet 58.1.0 → 58.2.0 and tokio
  1.52.1 → 1.52.2; refreshed Cargo.lock for in-range bumps across
  tower-http, wasm-bindgen, web-sys, webpki-root-certs, the
  arrow-* transitive set, and others. Trimmed unused features
  (tokio's full → eight specific features, dropped axum's http2
  feature and the standalone h2 direct dep), shrinking the
  transitive crate count. (#891)
• Viewer (server): enable reqwest's rustls feature so
  /api/v1/load_url can fetch HTTPS URLs. (#888)

Fixed

• Viewer: cgroup selector columns now truncate long names with
  ellipsis instead of widening past the flex split. (#873)
