From 818c0e17637f5403b53bbe273b4c0f8469bb8a39 Mon Sep 17 00:00:00 2001 From: James Maes Date: Fri, 9 Oct 2026 05:29:36 -0500 Subject: [PATCH 01/10] Deps: setup-dotnet v6, LibGit2Sharp 0.32 (security), Velopack, test tooling Dependabot has been closing its own PRs and failing weekly on actions/setup-dotnet ("no longer updatable") since the v6 release in July, so nothing has landed since. Bump everything it should have delivered: - actions/setup-dotnet v5 -> v6 in all five workflow usages (ESM migration only) - LibGit2Sharp 0.31.0 -> 0.32.0 (security release, bundles libgit2 1.8.6) - Velopack 1.2.0 -> 1.2.161 - Microsoft.Windows.SDK.BuildTools 10.0.28000.2270 -> .2705 - Microsoft.NET.Test.Sdk 18.7.0 -> 18.10.1, coverlet.collector 10.0.1 -> 10.1.0, xunit.runner.visualstudio 3.1.5 -> 4.0.0 (all three test projects) Verified locally: solution builds warning-free, 267 Engine + 65 CLI tests pass, coverage gate still reports 100% on gclo.Engine / gclo.ViewModels / gclo, dotnet format verify clean.

The workflow is now three jobs, each needing the previous: - verify: strict-semver tag check (unchanged) plus `git merge-base --is-ancestor origin/main`; a tag off main fails here and nothing downstream runs (push a v* tag on an unmerged commit to see it). - gates: calls ci.yml (new workflow_call trigger) so a release passes exactly what a PR does: zero-warning x64 build, 100% line coverage on Engine/ViewModels/Cli, the FlaUI UI smoke suite, and the format gate. The UI suite is not yet a required check on main PRs; it is required here. - release: the existing publish steps, reading version/channel from the verify job's outputs. contents: write is now scoped to this job only. Verified: all three workflows parse; the ancestry check was run locally and passes for v1.0.0 and origin/main and fails for the unmerged dev head. docs/RELEASING.md describes the three stages.

A rooted name, a traversal (../x), or a name with separators could operate outside the root the caller asked for. GitHub's own names are safe, but gclo.Engine ships on NuGet. New public RepositoryPathResolver: - TryValidateName: rejects blank, '.', '..', any directory separator (covers slash-rooted and UNC), ':' on every platform (drive-relative forms such as 'C:' and 'C:repo'), and file-system-invalid or control characters. - Resolve: normalizes root and candidate with Path.GetFullPath and requires the candidate to sit strictly inside the root, catching anything the textual checks miss (e.g. '...' which Windows normalization trims onto the root). The engine resolves every target before it creates TargetRoot, reports Queued, or calls the git client, so a bad name fails the whole call with an ArgumentException naming the repository and nothing on disk is touched. The git client now receives the normalized absolute folder. Tests: resolver unit tests (valid GitHub-style names, every rejection class, both separator styles, drive-rooted, UNC, containment backstop, relative and messy roots) and engine tests proving rejection happens before any side effect, for both the list and the lister overloads. Coverage gate stays 100%.

The next run treated it as an existing repository, saw equal commit tips, and returned "already up to date". The existing gclo.checkoutpending local-config marker (previously set only for Windows-invalid-path clones) is now set the moment the fetch lands, before anything is checked out, and cleared only after checkout completes. It is therefore durable evidence of an incomplete clone regardless of what interrupted it or whether cleanup succeeded. FetchAndPull already routes marked repositories through CompletePendingCheckout, which re-validates the tip's paths on Windows and force-checks-out the whole tree, so a marked repo is repaired rather than trusted. Empty-origin clones clear the marker so the unborn-HEAD path keeps handling them. Recovery metadata (.git/gclo-recovery.json) is checked first and is unaffected. Tests: a finished clone and an empty-origin clone leave the marker cleared; a marked repo with a partial tree and EQUAL tips is checked out instead of reported up to date; the same with the remote ahead materializes the new tip; a marked repo whose tip gained a Windows-invalid path fails with the typed exception and keeps the marker.

Both operations now have a fixed order and a compensating step: - Save with a token: vault write FIRST, then metadata. A vault failure changes nothing (Store either replaces the entry or leaves the previous one intact, so an update keeps the credential that worked). A metadata failure restores the previous token, or deletes the new entry for a brand-new account. - Delete: vault delete first, then metadata. A vault failure changes nothing. A metadata failure stores the removed token again, so a listed account never silently loses its credential and no token is left without its account. - In-memory state changes only after both stores succeeded. - When compensation itself fails, the new AccountConsistencyException states the exact leftover state and how a plain retry reconciles it (Save overwrites the vault entry and rewrites the file; Delete tolerates an absent entry), and the activity log records the same. Neither ever contains a token. ITokenVault.Store's contract now states the leave-unchanged-on-failure rule the store relies on; CredentialManagerVault already behaves that way (CredWriteW is an atomic replace) and InMemoryVault trivially does. Tests (AccountsStoreConsistencyTests, with a faultable vault and a recording log): vault-write failure for new and updated accounts, metadata-write failure with and without a token, compensation failure for save and delete, vault-delete failure, idempotent retry after every leftover state, and no token in any exception or log message. Coverage gate stays 100%.

On this repo it logged every newer package as "not compatible. Incompatible project frameworks: net10.0-windows10.0.19041", and because it updates a package consistently across projects, the same packages were blocked in the plain net10.0 test projects too. Net effect: WindowsAppSDK, Velopack, xunit.runner.visualstudio and Microsoft.NET.Test.Sdk were never offered, and the one PR it did open was closed by the bot itself. - .github/scripts/Update-NuGetPackages.ps1 drives the bump from `dotnet list package --outdated --format json` (real MSBuild/NuGet evaluation): applies minor/patch bumps by exact textual edit of each PackageReference (encoding and line endings preserved), holds major bumps and prereleases for review, and writes a Markdown report. Verified on a copy of the repo with four packages downgraded: three minor/patch bumps applied, the major held, and the edited csproj byte-identical to HEAD. - .github/workflows/nuget-updates.yml runs it weekly (Mondays 06:00 ET) or on demand (with an include-major switch), runs the build/test/format gates against the bumped tree, and opens or refreshes one PR on deps/nuget-weekly against dev with the report and gate results in the body. The third-party create-pull-request action is pinned to a commit SHA. With GITHUB_TOKEN the PR gets no checks of its own (GitHub does not chain workflows from it); an optional DEPS_PAT secret enables that. - dependabot.yml keeps only the github-actions ecosystem and explains why.

A flaky UI run that would never block a merge could therefore block an immutable tag. ci.yml gains a workflow_call input, ui-tests-advisory (default false), and the ui-tests job sets continue-on-error from it; push/PR runs are unchanged. The release workflow passes true, so build, coverage and format still block publishing and a red UI job is visible but not fatal. Documented in release.yml and docs/RELEASING.md as the explicit exception #44 allows; flip the input (and add the job to main's required checks) once the suite has earned it.
