fix(desktop): Nightly update checks find the newest nightly past newer preview builds - #35470
The desktop updater uses electron-updater's GitHubProvider. With allowPrerelease and channel=nightly, it only looks through the 10 entries of releases.atom for a release whose semver prerelease id is nightly. Preview builds published after the last nightly filled all 10 entries, so the check threw ERR_UPDATER_NO_PUBLISHED_VERSIONS. The fix extends the repo's existing patches/electron-updater@6.8.9.patch. When the atom scan finds no tag, allowPrerelease is on and a channel is set, a new getLatestChannelRelease pages GET /repos/{owner}/{repo}/releases?per_page=100 (at most 5 pages; it stops early on a short page) and returns the first non-draft, semver-valid release whose prerelease id equals the channel. Its tag then goes through the normal channel-file fetch (nightly*.yml). The release's name and body fill releaseName and releaseNotes when the yml has none, and the name still passes releaseNotesOfOfferedVersion ('T3 Code Nightly (...)'). Every case the feed already answered, and every stable check (allowPrerelease=false), takes the old path unchanged. The extra API call happens only where the old code would have thrown. Verified in Electron 44 under headless-desktop against live GitHub with the app at 0.1.9-nightly.20261110.4478 and the Nightly settings from applyAutoUpdaterChannel. Old package: ERROR ERR_UPDATER_NO_PUBLISHED_VERSIONS. Patched package: offers 0.1.10-nightly.20261112.4580 with its release name and notes. No new regex or parser: tags are checked with semver.valid/semver.prerelease and the response is JSON.parse'd, so cost is linear in the size of at most 5 pages of 100 releases.
Commit origin/main 55081a1. Installed deps (vp i) and fetched Electron 44.10.1. Ran a scratch Electron app with package.json version 0.1.9-nightly.20261110.4478 that loads the desktop app's bundled electron-updater 6.8.9, points it at an app-update.yml with provider github, owner pingdotgg, repo t3code (forceDevUpdateConfig), and applies the nightly-track settings from DesktopUpdates.applyAutoUpdaterChannel (channel=nightly, allowPrerelease=true, allowDowngrade=false, fullChangelog=true), then calls autoUpdater.checkForUpdates(). Ran it under headless-desktop with --no-sandbox --disable-gpu against live GitHub at about 18:02 UTC on 2026-11-12. Output: ERROR ERR_UPDATER_NO_PUBLISHED_VERSIONS No published versions on GitHub. At the same moment https://github.com/pingdotgg/t3code/releases.atom held exactly 10 entries, all 0.1.10-preview.20261112.* (4550 to 4593). The REST releases list still had v0.1.10-nightly.20261112.4580 (published 10:48 UTC) with nightly-mac.yml, nightly-linux.yml, nightly-linux-arm64.yml and nightly.yml. The newest preview release has no updater .yml assets.
Evidence
Evidence: Linux x64, Electron 44.10.1 under headless-desktop, light theme, 1100x780 app window, fresh isolated state, live GitHub. Both desktop bundles used updater package identity 0.1.9-nightly.20261110.4478; the built renderer displays repository version 0.1.9.
Steps on both commits: skip project imports, open Settings → About, confirm Nightly, and click Check for Updates from idle. Base failed with ERR_UPDATER_NO_PUBLISHED_VERSIONS; head found 0.1.10-nightly.20261112.4580 and offered Download. The Atom feed contained ten preview releases and no nightly entry.
A later additional head menu check encountered GitHub HTTP 403 after the shared unauthenticated API allowance was exhausted; the paired successful head capture predates it.
AI-assisted; verified with the tests and tools listed above.
Not shown:
Downloading/installing updates, other operating systems, and REST pagination beyond the first page were not exercised.
A later additional head application-menu check returned GitHub HTTP 403 due to exhausted unauthenticated API allowance; only the earlier matched Settings check demonstrated successful head discovery.
Tests
vp run check:changed: pass (unused patches, format, typecheck of 41 packages, 1 test file / 2 tests). Electron repro under headless-desktop against live GitHub: before = ERR_UPDATER_NO_PUBLISHED_VERSIONS; after = update 0.1.10-nightly.20261112.4580 offered with releaseName and notes.
Not in this change
Fallback release notes are only the found nightly's own body, not electron-updater's fullChangelog array across every release between the current and the offered version (the atom feed lacks those entries in this case).
The fallback uses the unauthenticated GitHub REST API (60 requests/hour per IP). It only runs when the atom feed has no matching release.
Preview releases could stop crowding the feed in the first place (for example by publishing them elsewhere or deleting old ones); that is a release.yml change.
AI-assisted; verified with the tests and tools listed above.
…r preview builds
electron-updater's GitHub provider looks for a prerelease of the selected
channel only among the 10 entries of releases.atom. Preview builds published
after the last nightly can fill that window, so a Nightly check failed with
ERR_UPDATER_NO_PUBLISHED_VERSIONS. When the feed has no release on the
selected prerelease channel, the patched provider now pages the REST releases
list for the newest non-draft one.
Fixes#35457

Macroscope's review found this PR approvable — Nightly update checks gain a bounded GitHub API fallback when newer releases crowd nightly builds out of the feed. Existing channel selection and download/install controls remain unchanged.

The patch updates the bundled Electron updater. It adds an idle timeout for HTTP requests and a GitHub releases API fallback for prerelease channels when the Atom feed has no matching tag.
The executor starts an idle timer with the request, resets it when response data arrives, and clears it on termination. If the timer expires, it aborts the request and reports Request timed out.
When the Atom feed has no matching tag and prereleases are enabled with a configured channel, the provider searches up to five pages of 100 releases. It skips drafts and invalid tags, then selects the first release whose first semver prerelease component matches the channel. The selected release supplies a missing name or notes.

Full details: Title check
Explanation
The title names the desktop nightly update check and the root cause: the updater only sees the newest nightly if it lies past newer preview builds. The changeset adds a REST-API fallback to the electron-updater patch that finds the newest matching channel release when the atom feed has no match, which is the same problem. The title uses the conventional commit form and is specific.
Full details: Linked Issues check
Explanation
[#35457] The issue requires the desktop nightly updater to find and offer the newest -nightly. release when the 10-entry releases.atom feed holds only preview releases. The raw summary shows getLatestChannelRelease(channel, cancellationToken) added to GitHubProvider in patches/electron-updater@6.8.9.patch. It runs only when the atom scan finds no tag, prereleases are allowed, and a channel is set. It pages GET /repos/{owner}/{repo}/releases?per_page=100 (at most 5 pages). It returns the first non-draft release whose semver-valid tag has a prerelease id equal to the channel. The normal channel-file fetch (nightly*.yml) then runs for that tag. This path replaces the ERR_UPDATER_NO_PUBLISHED_VERSIONS throw for the reported feed state. Existing feed matches and stable checks (allowPrerelease=false) keep the old path. The PR description reports a live-GitHub Electron run that offered 0.1.10-nightly.20261112.4580. The 'Evidence' section is still a placeholder. The reported run is therefore not yet recorded in the PR. The code path, not the placeholder, is the basis for this verdict. No automated test for the fallback is confirmed from the summary. The issue sets no test requirement, so this does not fail the verdict.
Full details: Description check
Explanation
The description follows the template's main sections (Problem, Change, Scope, Verification) with substantive content. It explains the nightly-channel failure with ERR_UPDATER_NO_PUBLISHED_VERSIONS and the fix that extends the electron-updater patch with a REST fallback. It links the issue (#35457) and gives reproduction steps, before/after evidence, and test results. It states what was not checked: other OSes, downloads/installs, and pagination beyond the first page. The Scope section is only partly template-aligned: it bundles a bug-fix justification and issue link, and the Change section does not separate the two independent concerns clearly. The description also repeats the AI-assisted disclaimer twice. These are minor issues. The Verification section is thorough and exceeds the template's minimum. The 'Problem' and 'Change' headings are not used literally; the content is embedded in prose paragraphs rather than under those headings, so a reviewer must infer the structure. Overall the description is mostly complete.
Full details: Out of Scope Changes check
Explanation
The raw summary lists an addTimeOutHandler(request, callback, timeout) method added to ElectronHttpExecutor in out/electronHttpExecutor.js. The change adds an idle timeout to all HTTP requests made by the executor. It aborts the request and reports Request timed out. The PR description and the linked issue #35457 do not mention this behavior. The described scope covers only the GitHub provider nightly fallback. The connection between a general executor idle timeout and the nightly feed fallback is not established in the PR. The change affects every updater request, not only the new REST call. Other changes (the provider fallback, supporting tests, and the patch file) are in scope for #35457.
Resolution
Remove the ElectronHttpExecutor idle-timeout change from this PR, or document its concrete purpose for the nightly fallback in the PR description. If it stays, cover its behavior with tests and link it to a tracked requirement. Confirm that the remaining patch still applies to electron-updater@6.8.9.

GitHub orders same-day releases by semver, so public `preview` tags outrank
