Problem

The failed-check "view log" icon never worked on oadp/velero/release PRs — hover and click always ended in "Failed to load log."

Two causes:

• CI artifacts for these repos live in the public test-platform-results-public bucket, and Prow "Details" links point at .../view/gs/test-platform-results-public/.... parseProwViewUrl only accepted the private test-platform-results bucket — which is not publicly readable anyway (JSON List API → 401, object GET → 403, gcsweb → Google sign-in page).
• The oadp analyze-e2e-failure post-step's report (failure-analysis.md / claude-failure-analysis-text.txt) was never looked up. It lands one level deeper than assumed: <job>/artifacts/<test>/oadp-analyze-e2e-failure/artifacts/failure-analysis.md.

Also: the walk capped both artifact levels at 10 entries — oadp e2e jobs have ~19 inner steps.

Changes

• Bucket fix — accept both result buckets, always walk the public mirror.
• Analysis — attach the analyze step's report as analysis; hover previews it, "Full log" shows it above the raw log.
• Inline grep panel — clicking the log icon toggles a scrollable panel of error lines under the failed check row (extractErrorLines, 16 patterns: ERRO, klog E1107, FATAL, panic:, [Fail], FAIL(ED|URE), make ***, timed out, deadline, exit status, OOM/CrashLoop/ImagePull), last N matches, max-height + overflow-y:auto. The icon toggles it closed; "Full log" keeps the modal.
• Opt-in live updates — Settings toggle (default off). Background fetches data-only logic.json from the Pages site (ETag, 60 s TTL, last-known-good on failure, status record); sanitizeLiveLogic whitelists selectors / grep patterns / caps; a version bump re-renders with a toast. Only JSON is fetched — never remote code — and fetch allowlists stay hardcoded in the background worker.
• Publishing — live/logic.json + live/index.html; .github/workflows/deploy-live-logic.yml validates and deploys to Pages. The loader tries github.tig.pw/github-bot-command-palette/logic.json then github.tig.pw/logic.json so either Pages layout works. Prerequisite: repo Pages Source = GitHub Actions.

Summary by CodeRabbit

• New Features

  • Added an opt-in setting for live updates to check detection and failure-log matching rules.
  • Failed-check icons now open an inline panel with matching error lines, failure analysis, or a log excerpt, plus access to the full available log.
  • Failure logs can include analysis reports, including when a step log isn’t available.

• Improvements

  • Live updates are cached and revalidated periodically; the last valid settings remain available if an update fails.
  • Expanded support for finding failure logs and analysis reports across supported result links.

Walkthrough

The pull request adds failed-check log retrieval and an inline error view with a full-log modal. It also adds opt-in live logic updates, configuration controls, a GitHub Pages deployment workflow, and tests and documentation for both features.

Changes

Failed-check logs

Layer / File(s)	Summary
Retrieve logs and analysis background.js, tests/background.test.js, backlog/tasks/task-16 - Fix-failed-check-view-log-icon-and-oadp-failure-analysis-report.md	Prow lookup accepts both results buckets and reads artifacts from the public bucket. It scans all test and step directories for failed-step logs and analysis reports. Results can include both, or analysis alone.
Render the failure-log panel content.js, styles.css, README.md, tests/content-helpers.test.js, tests/failed-step-log.spec.js, tests/fixtures/pr-with-failed-check.html	The failed-check icon opens an inline panel with matched error lines or fallback content. A full-log modal displays available analysis and log text. Tests cover extraction, panel behavior, and modal content.

Opt-in live logic

Layer / File(s)	Summary
Configure and fetch live logic config-export.json, config-manager.js, settings.html, settings.js, manifest.json, background.js, tests/background.test.js	A disabled-by-default setting controls live logic retrieval. The background handler caches responses, revalidates with ETags, tries a fallback URL, and returns cached data on errors.
Sanitize and apply live logic content.js, tests/content-helpers.test.js, tests/failed-step-log.spec.js	The content script sanitizes supported fields and applies selector and error-pattern overrides. It refreshes while the tab is visible and can show a toast when the version changes.
Validate and publish live logic .github/workflows/deploy-live-logic.yml, live/*, README.md, backlog/tasks/task-17 - Inline-grep-error-log-panel-and-opt-in-live-logic-updates.md	The workflow validates live/logic.json, assembles the Pages site, and deploys it. The JSON, information page, README, and task record describe the data and deployment.

Merge Risk: Moderate · previous review 9cd38

Resolve the log-panel and retrieval failures before merging. Live updates are off by default, but enabling them can stall controls or apply data after opt-out. The browser tests also need controlled endpoint responses so deployment does not break them.

minimal, and validate.

Inline comments:
Review comments at @.github/workflows/deploy-live-logic.yml:
- Around line 45-48: Update deployment validation for logic.errorLinePatterns
and the other selector so both are checked before publishing; in the content
script, discard invalid selector overrides and use the built-in selectors
instead. Preserve valid overrides and avoid applying a live update when either
selector fails validation.
- Around line 45-48: Update the deployment validation around the `logic.version`
and `errorLinePatterns` checks to compare the incoming document with the
currently deployed version, and reject pattern changes that do not include a
version bump. Allow initial deployments and redeployments with unchanged
patterns; use the workflow’s established deployment state rather than assuming
an unavailable comparison API.
- Line 45: Update the `logic.version` validation to reject non-finite values as
well as non-numbers before deployment, while preserving the existing validation
error behavior.
- Line 38: In the deploy-live-logic workflow, replace the floating action
references, including actions/checkout@v7, with verified full-length commit SHAs
for all four actions; preserve the intended action versions and deployment
behavior.

Review comments at @background.js:
- Around line 678-682: Update the live-logic failure paths near liveLogicFailure
so failed endpoint attempts are recorded for the TTL, preventing immediate
retries on subsequent injections. Preserve the last good logic and the existing
error status when updating the cache timestamp.
- Around line 933-939: Update the failedStepDir branch in the log lookup so a
missing build-log.txt does not abort the lookup or discard an existing analysis
report. Handle the fetch failure and continue through the existing fallback-log
path, returning the analysis-only result when no fallback log is available.
- Line 904: Update the report-selection logic associated with analysis so it
resolves the report from the failing test’s directory, rather than reusing a
report left by an earlier test when that test’s failure status cannot be read;
ensure the selected test’s hover and Full log show only its associated report.

Review comments at @content.js:
- Around line 1273-1274: Update the inline log panel placement around
inlinePanel.panel so it appears in a separate full-width row below the check
row, rather than inside the non-wrapping row; keep the panel’s contents and
controls accessible.
- Around line 99-102: Replace the compile-only validation in the live pattern
loading path with a matching approach that bounds execution time, so a
catastrophic backtracking pattern cannot block the GitHub tab when matching log
lines. Establish a safe mechanism, such as a bounded-time matcher or isolated
execution with an effective timeout, before adding patterns to the matching
flow; do not rely on compilation checks or the existing length limit.
- Line 3462: Update refreshLiveLogic so live-logic retrieval has a deadline
covering both the request and response-body consumption; if it expires or
revalidation stalls, continue with cached logic or the established default so
initial and later injections can render controls.
- Around line 3536-3538: Update the periodic refresh that calls debouncedInject
so it does not remove an open inline failure log or reset its scroll position.
Reinject only when the underlying logic changes, including when live updates are
disabled or unchanged, or preserve the panel and its scroll position across
reinjection.
- Around line 1104-1108: Update the cached-result handling around the `resp` and
`result` assignment to distinguish raw logs without analysis from complete
results. When a cached partial result is used for a hover preview or Full log
open, revalidate or reuse the report-fetch flow, then update the cached result
when analysis becomes available while preserving the raw log.

Review comments at @live/index.html:
- Around line 19-21: Update the Live updates description in the HTML paragraph
to describe that changes are picked up through polling without promising a
60-second deadline or immediate availability; retain the condition that Live
updates must be enabled.

Review comments at @manifest.json:
- Line 7: Remove github.tig.pw from the required host_permissions in the
manifest and request it as an optional host permission only when the user
enables live updates. Handle a denied permission request by keeping live updates
disabled; locate the existing live-update setting and permission flow, and reuse
their established state and error handling.

Review comments at @settings.js:
- Line 88: Update the settings save flow that assigns
config.globalSettings.liveUpdates from the opt-live-updates checkbox so it
writes that value only when the user changed the live-updates setting. Otherwise
preserve the stored value, preventing unrelated saves such as theme changes from
re-enabling live updates.
- Line 88: Update the live-updates opt-out flow around the
globalSettings.liveUpdates assignment to invalidate any pending live-logic
requests, and check that each response is still current and live updates remain
enabled before assigning it to liveLogic. Preserve the existing response
handling when updates are enabled.
- Line 56: Update the opt-in check in refreshLiveLogic to enable live fetching
only when config.globalSettings.liveUpdates === true; treat strings and other
non-boolean values as disabled.

Review comments at @tests/failed-step-log.spec.js:
- Around line 207-208: Update the test around the live response assertions so it
accepts valid and not-modified responses from the deployed endpoint instead of
requiring live.source to equal error. Test successful responses separately from
a controlled outage, preserving explicit error-path coverage without depending
on the deployed endpoint failing.
- Line 130: Update the live-test setup in the test containing test.setTimeout so
GHBCP_LIVE_PR=1 uses the authenticated profile from .test-profile, and ensure
cleanup does not delete that profile. Keep fixture tests isolated from the
shared authenticated profile.
- Around line 184-191: Add an integration test alongside the existing opt-in
test that serves a controlled successful live-logic document with a non-default
selector or error pattern, then asserts the resulting page behavior reflects
that override. Verify the behavior itself rather than only that the page loads
or a live-logic attempt was recorded, so the test fails if refreshLiveLogic()
ignores overrides.

In code that hasn't changed since last review

Try logs from later failed steps before job-level fallbacks

background.js:938

Once the first failed step is found, later failures are skipped before checking whether that step's log is readable. If its build-log.txt is missing but a later failed step has an available log, the walk incorrectly falls through to job-level fallbacks. Collect the failed candidates and try their logs in order before using those fallbacks.

In code that hasn't changed since last review

Backtracking regexes can freeze the GitHub tab

content.js:80

The sanitizer accepts exponential-backtracking patterns such as (a|aa)+$, which can freeze the GitHub tab on a nonmatching log line even within the 500-character cap. The 250 ms deadline cannot interrupt a synchronous RegExp.test(). Restrict live patterns to a demonstrably safe subset or run matching in a terminable worker with an enforced timeout.

🔵 Needs a closer look

Human assessment is needed because subtle permission-save races, tab-freezing regex backtracking, and deployment validation gaps create risks across several parts of the change.
