Summary

Dependabot cannot watch most NuGet packages in this repository. Its NuGet run on 2026-11-02 logged The package CsCheck.5.0.0 is not compatible. Incompatible project frameworks: net10.0-windows10.0.17763. It logged the same for CsCheck 4.9.1 and WPF-UI 4.3.0, then No updatable version found, and finished green. Every NuGet pull request it ever opened here moved Meziantou.Analyzer or CsWin32, the two packages that carry no assembly.

This adds a weekly check that asks nuget.org itself.

  • .github/workflows/outdated.yml runs:

    • every Tuesday, the day after Dependabot's Monday run,
    • by hand,
    • on pull requests that touch it.

    It restores on Linux, takes dotnet list package --format json, and hands that to the gate. It runs with read-only permissions, and actions are pinned by commit like everywhere else. It is not meant to be a required check.

  • .github/scripts/outdated_gate.py asks NuGet's registration (found through the service index) for every version of every package, with dates. It is red when the tree is behind a listed version older than the cooldown. It reads that cooldown from the NuGet entry of dependabot.yml rather than repeating the number. A version still inside the cooldown is listed and not red. Prereleases count only when the tree is on a prerelease of that package. Exit codes follow the other gates: 0 satisfied, 1 found, 2 could not read.

  • The gate refuses rather than passes when its input is incomplete:

    • a listing that misses a project git tracks,
    • a listing that misses a package some PackageReference names,
    • a listing that reports a problem,
    • a package whose own version is not among the versions read, which would mean a registration page went unread.
  • .github/outdated/held.toml holds newer versions the tree deliberately does not take. Each entry names the highest version covered, a date and a reason. A newer version, the date passing, or an entry that holds nothing any more makes the check red again. Unknown keys are refused.

    • It holds one package: coverlet.collector through 10.1.0, until 2026-12-01. The coverage floors are held to a tenth of a point and coverlet 10 counts differently, so that move needs its own pull request.
  • dependabot.yml: the comment on the NuGet entry now says what the entry does and does not do, measured on that run. The sentence about Meziantou.Analyzer and Directory.Build.props is no longer marked as unverified, because the same run shows it.

Expected result on this pull request

Red, for one reason: main still has CsCheck 4.9.1, and 5.0.0 has been on NuGet since 2026-10-24. That is the move in #105. Once #105 is merged into this branch, the expected result is green, with Meziantou.Analyzer 3.0.320 listed as cooling until 2026-11-06.

Checked

  • selftest: 45 known cases, the red ones included.
  • canary against nuget.org: Newtonsoft.Json 12.0.3 comes out behind 13.0.4 on a major step.
  • verdict on this tree, run locally against nuget.org:
    • behind: CsCheck,
    • held: coverlet.collector,
    • cooling: Meziantou.Analyzer,
    • current: the other six packages.
  • The same tree with dotnet list package --outdated, NuGet's own answer without a cooldown: the same three packages with the same newest versions, and nothing else.
  • The gate was broken five ways in a copy, and the self-test or the canary went red every time:
    • cooldown ignored,
    • registration pages skipped,
    • nothing ever newer,
    • prereleases always counted,
    • holds never expiring.
  • Architecture guards for workflows, prose, the public surface and the supply chain: 28 of 28. Changing one pinned action in the new workflow to a tag turned WorkflowGuards red, so the guard reads the new file.
  • The Linux restore with the two settings passed through the environment is NOT checked locally. This pull request's own run is that check.

Summary by CodeRabbit

  • Chores
    • Added automated checks that report whether tracked NuGet packages are current, still within a cooldown period, or behind.
    • Checks can run on a schedule, on demand, and when related configuration changes. Reports include package status and any hold-file issues.
    • Added safeguards for incomplete package listings and unavailable or invalid package data.
  • Documentation
    • Added guidance for recording temporary package holds and their expiration dates.

Dependabot's NuGet updater reports every package that carries an
assembly as not compatible with net10.0-windows10.0.17763, logs that no
version can be updated, and finishes green. Every NuGet pull request it
opened here moved one of the two packages that carry no assembly, so
the window's control library, the test framework and the property-based
testing library only ever moved when somebody happened to look.

outdated.yml runs every Tuesday, the day after Dependabot, and on pull
requests that touch it. It restores, lists what NuGet resolved, and asks
the registration of each package for its versions and their dates. It
is red when the tree is behind a listed version older than the cooldown
in dependabot.yml, which it reads rather than repeats. A younger version
is listed and is not red.

A newer version the tree deliberately does not take goes into
.github/outdated/held.toml with the highest version covered, a date and
a reason. coverlet.collector 10 is held until 2026-12-01, because the
coverage floors need a pull request of their own to measure it.

The gate refuses a listing that is missing a tracked project or a
referenced package, and a package whose own version is not among the
versions it read. Before every run it tests its decisions on known
cases, and a package years behind has to come out behind.

The comment on the NuGet entry of dependabot.yml now says what that
entry does and does not do, measured on the same run.

These are guards rather than preferences. Each one exists because the thing it forbids happened at
least once, and most of them read the compiled assemblies or the source tree rather than trusting
a declaration:

Walkthrough

Adds a Python NuGet freshness gate that reads resolved package listings, compares releases against cooldown and hold rules, and reports package states. A GitHub Actions workflow runs its self-test, canary, restore, listing, and verdict on scheduled, manual, and selected pull-request events.

Changes: NuGet freshness gate

Layer / File(s) Summary
Parse versions and retrieve releases
.github/scripts/outdated_gate.py
The gate parses and orders NuGet versions, discovers registration data, and reads inline or paged releases with response limits and retries.
Validate inputs and judge package status
.github/scripts/outdated_gate.py, .github/outdated/held.toml
The gate validates package listings and hold entries. It classifies packages using listed releases, publication dates, cooldowns, and active holds.
Report verdicts and validate behavior
.github/scripts/outdated_gate.py
The gate adds canary and verdict commands, Markdown summaries, self-tests, and CLI exit statuses.
Run the gate in GitHub Actions
.github/workflows/outdated.yml, .github/dependabot.yml
The workflow runs on a weekly schedule, manual dispatch, and selected pull requests. It runs the tests and canary, restores and lists packages, then invokes the verdict. Dependabot comments record observed update behavior and reference the check.

Full details: Tests For Changed Behavior

Explanation

The PR adds non-UI behavior in .github/scripts/outdated_gate.py, and it also adds a selftest() suite with assertions for version ordering, cooldowns, prereleases, holds, input validation, registration paging, size limits, and canary outcomes. .github/workflows/outdated.yml runs this self-test before the gate. The PR changes no existing test files and deletes or weakens no tests.

Full details: No Secrets Or Debug Leftovers

Explanation

The pull request adds only the four reviewed repository files. It adds no CLAUDE.md, CLAUDE.local.md, AGENTS.md, .claude/, or .env path. The only production URL is the public NuGet service index; the other URLs are self-test fixtures. No credentials, personal email, private host, IP address, or machine-specific user path is present. The print calls provide normal gate and self-test output, not leftover debug output; traceback.print_exc is deliberate unexpected-error reporting.

Full details: No Hardcoded Ui Styling

Explanation

PASS: The pull request changes only .yml, .toml, and .py files under .github. The diff adds a package-check script and workflow, not XAML, Slint, Fyne, Tkinter, or WPF UI code. The check is therefore not applicable.

Full details: No Obvious Performance Problems

Explanation

No clear performance problem is introduced. The workflow runs weekly or on relevant changes, not through polling or a frequent timer. The gate performs one NuGet registration lookup per distinct package and caches each package's release list during the verdict; the repository currently has a small set of projects and package references. The remaining collection scans are linear or small validation loops, with no UI-thread work, non-virtualized UI, or avoidable per-item external process.

Full details: System Changes Are Reversible

Explanation

PASS: The pull request adds a NuGet query and a read-only package-check workflow. The script performs HTTPS GET requests, reads repository files, runs read-only Git commands, and appends the workflow summary. It does not modify network filters or rules, proxies, firewalls, system time, processes, services, registries, or drivers. The reversibility warning condition is not applicable.

Full details: Scope, Duplication And Docs

Explanation

All changed files are within the stated feature scope: the Dependabot comment, the new hold file, the NuGet gate, and its workflow. The PR description covers the workflow triggers, CLI commands, cooldown, hold format, exit states, and expected results. The repository has separate standalone CI gate scripts, but no existing NuGet freshness gate or shared service layer that this change bypasses. The new CLI and hold format are additive, not backward-incompatible. The script, workflow, and hold file document their interfaces, and CHANGELOG.md explicitly excludes internal CI changes.

Full details: Desktop Robustness

Explanation

The new gate loads repository data relative to the current working directory. canary() opens .github/dependabot.yml directly at .github/scripts/outdated_gate.py:440, and the workflow passes .github/outdated/held.toml as a relative path. The gate therefore depends on GitHub Actions starting in the repository root. The PR also makes NuGet calls, but the workflow and script explicitly document those calls, so that condition is satisfied.

Resolution

Resolve the repository root once, for example from __file__ or git rev-parse --show-toplevel. Use that root for .github/dependabot.yml, the default held-file path, and other repository inputs. Resolve or validate CLI paths before opening them so the gate works from any working directory.

Full details: Safe File Parsing

Explanation

The new gate has unsafe parsing paths. REFERENCE.findall uses a backtracking regex over unbounded .csproj/.props/.targets text. A malformed file containing repeated &lt;PackageReference tokens makes the pattern superlinear; the equivalent pattern took about 10 seconds for 8,000 tokens. json.load, tomllib.loads, and stream.read() also have no size limit for the listing and repository files. In addition, urllib.request.urlopen accepts the unvalidated @id values from NuGet JSON; file:///etc/hosts is readable through this API, so a crafted service-index or registration response can make the job read outside the intended NuGet endpoint.

Resolution

Replace REFERENCE.findall with a bounded defusedxml.ElementTree parse and reject DTD/external entities and malformed XML. Add a shared capped-file reader before json.load, tomllib.loads, and XML parsing, and refuse files over a fixed limit. Validate every service-index and registration @id with urllib.parse.urlsplit: require HTTPS and an allowlisted NuGet host, reject credentials, nonstandard schemes, and cross-host redirects; use a redirect handler that applies the same validation. Also require decompress() to reach gzip EOF before parsing.

Full details: Clear User-Facing Text

Explanation

The new gate exposes a raw Python traceback to workflow users. In main, the unexpected-exception path calls traceback.print_exc() at .github/scripts/outdated_gate.py:729-733, before printing its refusal message. This violates the requirement that an error must not show a raw exception.

Resolution

Remove traceback.print_exc() from the user-facing path. Print a concise message such as REFUSED: the gate encountered an unexpected error and could not produce a verdict. Check the workflow log and rerun after fixing the input. If diagnostics are required, store them separately instead of displaying the traceback.

Full details: No Resource Leaks

Explanation

fetch_json() closes successful responses with with, but it does not close urllib.error.HTTPError responses. At .github/scripts/outdated_gate.py:206-210, the handler retains the exception in last for HTTP 429 and 5xx retries, and raises for other HTTP errors without calling exc.close(). HTTPError is also a file-like response and can retain its underlying socket. This is an error-path HTTP response leak introduced by the PR.

Resolution

In the HTTPError handler, close exc on every path, including before retry and before raising Unreadable (use try/finally). Retain only the status or a closed exception for the retry message. Add a self-test or mocked error-response test that verifies close() is called for retryable and non-retryable HTTP errors.

Strip XML comments before scanning for PackageReference.

declared() counts a <PackageReference> inside an XML comment. NuGet never lists that package, so tree() raises Unreadable and the weekly check exits 2. A PackageReference whose Condition is false for every framework has the same effect. This diff does not cover the conditional case, because evaluating MSBuild conditions needs property evaluation the gate does not perform.

Update declared() to strip XML comments from each text before scanning with
REFERENCE.findall, so commented-out PackageReference elements are excluded. Keep
the existing package-name extraction behavior and do not add MSBuild condition
evaluation.

Refuse boolean version values in tree.

listing.get("version") != 1 accepts true, because Python compares True equal to 1. A listing with "version": true and otherwise current data passes, and verdict exits 0. Exclude booleans before the value comparison.

Suggested fix
-    if not isinstance(listing, dict) or listing.get("version") != 1:
+    if not isinstance(listing, dict) or isinstance(listing.get("version"), bool) or listing.get("version") != 1:

Add a version: True case next to the existing version=2 case in selftest, so the self-test covers this input.

Collapse newlines in hold notes before writing the table row.

summary_table escapes | in judgement.note but leaves newlines in place. A multiline reason in held.toml (a TOML """ string, or an escaped \n) puts a line break inside a one-line Markdown table row. The rest of that row then moves to a separate source line. The step summary shows a broken package row and part of the reason outside it. The verdict and exit code are not affected.

Normalize whitespace in the note before the pipe replacement:

Suggested fix
-            judgement.state + (" - " + judgement.note.replace("|", "/") if judgement.note else ""),
+            judgement.state + (" - " + " ".join(judgement.note.split()).replace("|", "/") if judgement.note else ""),

Compare package references per project in tree.

tree compares PackageReference names with listed packages across all projects together, so a package dropped from one project still passes when another project lists it. If c.csproj loses a package that a.csproj still lists, the check passes and that project's version is never judged. Record references per project file, check each tracked project against its own listed packages, and add a self-test that removes one package from one project only.

Check each registration page's count against its leaves.

releases_of never reads the count field that NuGet requires on each registration page. A page with fewer leaves than its count is accepted. If a missing leaf holds a newer version, judge reports current and the verdict stays green.

Suggested fix
         leaves = items(page, "items", where)
         if "items" not in page:
             page = fetch(field(page, "@id", str, where))
             leaves = items(page, "items", where, required=True)
+        advertised = field(page, "count", int, where)
+        if advertised != len(leaves):
+            raise Unreadable("%s has %d leaves, not the %d its count names" % (where, len(leaves), advertised))
         for leaf in leaves:

The self-test pages in the changed hunk have no count, so the self-test refuses them once this check exists. Add count to each fixture page. Add a case where a page advertises more leaves than it lists, and expect Unreadable.

Update `releases_of` to validate that each registration page’s required `count`
matches the number of leaves after any page fetch, and raise `Unreadable` on a
mismatch. Update the self-test registration-page fixtures to include accurate
`count` values and add a test asserting that a page advertising more leaves than
it lists is rejected.

The review of the outdated-package gate found that every address it
opened came from NuGet's own answers and went straight to urllib, which
also opens file:// URLs. Every address is now checked before it is
opened, redirects included: HTTPS, on the host of the service index,
with no credentials and no other port.

Project files are read with the XML parser instead of a pattern, so a
reference inside a comment is no longer a reference, and a document
type declaration is refused before parsing. A reference written in a
project file now has to be in that project's own listing, not only
somewhere in the listing. The page counts NuGet gives for a
registration and for each page have to match what was read.

Smaller things from the same review: an HTTPError is closed on every
path, a compressed answer has to reach its end, every repository file
is read under the size ceiling, a true is not taken for a number, the
canary finds dependabot.yml from the repository root, a reason written
over several lines stays in one table row, and an unexpected stop
prints its verdict before the traceback.

The self-test holds on to the errors it raises, because CPython closes
an error's body by itself once nothing refers to it, and without that
the check could not tell a gate that closes from one that does not.
