Adds Google integration regressions for required KMS keyring and metastore migration resource operands, optional selectors, required service options, and constructor null guards.

The source fixes are on main. Full generation on SDK 585.0.0 now parses the previously failing leaf commands; run 35058181945 stopped on 354 missing group-dispatch paths. Source PR #5167 fixes that remaining coverage defect with 852 passing focused tests. It will merge after the active AWS refresh to preserve generation provenance, then gcloud will regenerate from latest main.

The generated-constructor and service-contract findings remain open until fresh generated output is incorporated and Google integration CI passes. Local Google builds previously reached the unchanged 2 GB guard; heavy validation remains in CI. Scoped formatting passes.

Refs #4850, #5146, #5166.

Source fix is pushed at ec417e6. Full gcloud regeneration is queued in run 34829736260 from that exact commit, with automatic merging and coverage-shrinkage approval disabled.

The issue remains open until the generated records/services and provenance are incorporated and the Google contract tests pass. The preserved source worktree and its verified backup remain intact; unrelated commits from that old branch were not replayed.

Greptile Summary

Adds Google Cloud integration contract tests for positional resource arguments.

  • Verifies KMS keyring deletion and metastore migration methods require typed options.
  • Verifies fully qualified and selector-qualified resource argument rendering.
  • Verifies missing required resources are rejected.
  • Generated Google option records and service signatures required by these tests are still absent from the PR.

Confidence Score: 4/5

The PR is not yet safe to merge because its new integration contracts still require generated Google options and service signatures that are absent.

The previously reported generated-API gap remains unresolved: current resource service methods still accept optional options, and the expected resource constructors have not been generated. thomhurst confirmed that generated options, services, API artifacts, and provenance would be incorporated before merging, but those outputs are still absent from the current head.

P1 Generated APIs Are Missing

These tests require regenerated Google APIs, but this PR does not include them. The checked-in option records remain parameterless, and the service methods still accept optional options. As a result, Resource_Service_Requires_Options fails, while the other tests cannot find the expected string constructor. Regenerate and commit the Google options, services, and provenance so the integration exposes this fix and the tests pass.

P1 Badge Regenerate the affected gcloud APIs

The checked-in option records still have only parameterless constructors and lack the resource, Location, and Service properties, while their service methods still accept optional options. Consequently, all three calls to GetConstructor([typeof(string)]) return null and these new integration tests fail; more importantly, consumers still cannot supply the resource operands this commit is intended to restore. Regenerate and commit the Google options and services from the updated scraper.

Code review

This is a well-scoped generic fix: the gcloud scraper now runs `POSITIONAL ARGUMENTS` sections through the same shared `CliArgumentGroup`/`ParseArgumentGroups` machinery used for flags, adds `CliArgumentDefinition.IsPositional` to distinguish operands from switches, and teaches `UsageSynopsisParser` to parse the `(OPERAND : --selector=VALUE)` resource-group synopsis shape generically (`TryParseResourceOperands`), rather than hard-coding anything gcloud-specific in the synopsis parser. The regex changes and `IsEnabled` log guards are reasonable, low-risk cleanups. I traced the new/renamed helpers (`NormalizePropertyName`, `GetPositionalArguments`, `ParseArgumentGroups`, `CliPositionalArgument.MergeDuplicates`, the `ExtractArgumentSections`/`ParseOptions` signature changes) and they line up correctly with their call sites and with PublicAPI.Unshipped.txt.

One thing worth double-checking before this merges: test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs (new in this PR) will fail against the currently-committed generated code. It does things like:

  • optionsType.GetConstructor([typeof(string)])!.Invoke([resource]) — but src/ModularPipelines.Google/Options/GcloudKmsKeyringsDeleteOptions.Generated.cs and the metastore migrations describe/delete options are still empty records with no operand constructor.
  • optionsType.GetProperty("Location")!.SetValue(...) / "Service" — those properties don't exist yet on the generated records.
  • serviceType.GetMethod(methodName)!.GetParameters()[0] asserted to equal optionsType (non-nullable) and IsOptional false — but GcloudKmsKeyrings.DeleteAsync / GcloudMetastoreServicesMigrations.DescribeAsync/DeleteAsync still take ...Options? options = null.

This matches what's already flagged in the PR description and your own follow-up comment (regeneration queued in a separate run, issue #4850 staying open until generated records/services/provenance are refreshed) — so it's not news, just confirming from the test side that this PR isn't self-contained/mergeable until that regeneration lands and gets incorporated, per the repo's "current tool output is authoritative, never hand-edit generated options" rule. Worth keeping this PR (or the merge) gated on that follow-up so the new test file doesn't land red.

No other correctness issues found in the parser/generator logic itself.

Pushed the colon-group review fix at d06134c856d9a8c57d16cebc384e8d80fafb4d75 and rebased onto current main. Full gcloud regeneration is queued in run 34834428341; the earlier source request is superseded. Generated output and all 12 Google integration contracts remain merge requirements.

All 762 scraper tests and the six scheduler tests pass locally. The prior CI failure was a timeout in the unchanged core scheduler test's five-second second-read deadline, rather than a generator assertion failure. It did not reproduce locally. A fresh parent CI cycle is required; no rerun was requested to hide the failure.

Review

This is a solid generic fix for the underlying scraper bug (routing POSITIONAL ARGUMENTS through the shared CliArgumentGroup/ParseArgumentGroups machinery and teaching UsageSynopsisParser to parse the (OPERAND : --selector=VALUE) resource-group shape), but the PR as it stands at d06134c does not compile, and one previously-flagged blocker is still outstanding.

1. Compile-breaking syntax — new in this PR (blocking)

tools/ModularPipelines.OptionsGenerator/src/ModularPipelines.OptionsGenerator/Scrapers/Cli/UsageSynopsisParser.cs:16,36,47

The ControlTokens, OptionControlTokens, and CommandGroupPlaceholderNames HashSet<string> fields were rewritten from new(StringComparer.OrdinalIgnoreCase) { ... } to collection-expression literals containing with(StringComparer.OrdinalIgnoreCase), as the first element:

private static readonly HashSet<string> ControlTokens =
[
    with(StringComparer.OrdinalIgnoreCase),
    "arg",
    ...
];

with(...) as a bare call inside a [...] collection expression isn't valid C# — there's no such method, and with is only usable as expr with { ... } on a record/struct. This is CS0103 at all three sites, so ModularPipelines.OptionsGenerator fails to build, which means none of the new tests in this PR (including GcloudResourceArgumentTests.cs) can run despite the PR description's claim that "all 762 scraper tests pass." Since collection expressions can't carry a comparer this way, the fix is to keep the constructor form: new HashSet<string>(StringComparer.OrdinalIgnoreCase) { ... }.

2. Generated Google options not regenerated (blocking, carried over)

test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs still can't pass against the committed generated code — this matches what github-actions already flagged on ec417e6 and what you and Greptile both acknowledged is pending a separate regeneration run. Confirmed still true at d06134c: GcloudKmsKeyringsDeleteOptions.Generated.cs and the two metastore-migrations options files are still empty records with no string-parameter constructor or Location/Service properties, and the corresponding service methods still take optional Options? options = null. CreateOptions in the new test does GetConstructor([typeof(string)])!.Invoke(...), which will NRE. No action needed from me here beyond confirming it's unresolved — just flagging that the verdict below reflects the PR's current, not eventual, state, consistent with the repo's "current tool output is authoritative" rule.

3. Possible ordering/requiredness bug in the new synopsis-fallback merge (worth a look)

tools/ModularPipelines.OptionsGenerator/src/ModularPipelines.OptionsGenerator/Scrapers/Cli/GcloudCliScraper.cs:470-496 (ParsePositionalArguments)

For a grouped positional operand with no synopsis match, the fallback assigns:

PositionIndex = usageArguments.Count + index,

where index is the operand's position among all grouped positional operands, not just the unmatched ones. If an unmatched operand sits between two synopsis-matched operands in declaration order (matched operands keep their small synopsis-derived index), the final .OrderBy(argument => argument.PositionIndex) will sort the unmatched one after both matches even though it appeared in between — e.g. declared order A, B, C with only A and C present in the SYNOPSIS becomes generated order A, C, B. CliPositionalArgument.MergeDuplicates re-numbers PositionIndex sequentially afterward, but it does so using this already-wrong sort order, so it doesn't correct it — the generated [CliArgument(n, ...)] attributes would pass positional arguments to the CLI in the wrong order. The same fallback branch's required = argument.ValueHint?.StartsWith('[') != true is also suspect: your own Optional_Resource_Can_Use_Configuration_Without_An_Operand test shows optionality for gcloud resource groups is only expressed via the SYNOPSIS colon-group bracket, not the leaf operand line, so any unmatched operand will default to IsRequired = true even when it's actually optional.

None of the three new fixtures exercise an unmatched-operand case, so this wouldn't show up in the added tests — worth either a fixture that has a grouped positional operand absent from SYNOPSIS, or reworking the fallback to compute its index only among unmatched operands (e.g. track unmatchedIndex separately) rather than reusing the full-list index.

Minor: duplicated section-boundary regex

GcloudCliScraper.cs's new ExtractArgumentSections (using ArgumentSectionHeadingPattern) re-implements the same "find the next ALL-CAPS heading" boundary logic as the existing ExtractFromSection (using SectionBoundaryPattern), via two slightly different regexes. A shared boundary-matching helper would remove the duplication and the risk of the two drifting apart on future help-text edge cases (e.g. CRLF handling).


Everything else — the generic (non-gcloud-specific) approach in UsageSynopsisParser.TryParseResourceOperands, the CliArgumentDefinition.IsPositional addition, and the validation split between positional operands and switches in CliScraperBase — looks sound and appropriately scoped to the shared parsing layer rather than hard-coded per-command.

Pushed review fixes and the main rebase at 087a24715a37e23f8cf791c309b4c53e9115715f.

  • Ordering/requiredness: an extracted synopsis that omits a declared operand now fails with a diagnostic instead of appending or guessing. Two regression cases failed before the fix; declaration-only help preserves its explicit order and bracket optionality.
  • Wrapped synopses: the authoritative metastore fixtures exposed a shared parser defect that treated continuation lines as separate synopses. Deeper lines now join their command, while alternatives remain separate. Four targeted cases and the real resource fixtures pass.
  • Section boundaries: command discovery and argument parsing now share one heading matcher and extraction helper, retaining current main's default-annotation behavior.
  • Compiler concern: with(StringComparer.OrdinalIgnoreCase) is accepted by the repository's pinned SDK 10.0.401 with LangVersion=preview. The Release generator solution builds with zero warnings/errors, and all 847 scraper tests execute successfully. No syntax workaround is needed.
  • Generated output: still outstanding. Both output threads remain unresolved and all 12 Google integration regressions remain enabled. Cancelled feature run 34834428341 will not be resumed; source prerequisites must land before fresh latest-main generation. A separate source PR is required if these output regressions block source landing.

Scoped severity-info formatting/verification, all 61 API baselines, and diff checks pass. Earlier 2 GB validation limits remain deferred to CI. A subsequent CI/review cycle is required before merge.

Review

This is a well-designed generic fix for a real scraper gap: POSITIONAL ARGUMENTS sections now flow through the same shared CliArgumentGroup/ParseArgumentGroups machinery as FLAGS, CliArgumentDefinition.IsPositional cleanly distinguishes operands from switches, and UsageSynopsisParser learns the (OPERAND : --selector=VALUE) resource-group shape without any gcloud-specific hard-coding. The switch from silently guessing operand order/requiredness to throwing when a synopsis omits a declared operand (GcloudCliScraper.cs ParsePositionalArguments) is the right call — it correctly addresses the ordering bug flagged on the previous revision (d06134c), and the shared ExtractSections/SectionHeaderPattern consolidation resolves the duplicated section-boundary regex noted there too. Good test coverage of the new synopsis shapes (wrapped continuations, colon groups, missing-operand rejection).

However, two issues remain in the current head (087a247):

1. UsageSynopsisParser.cs:945-982with(...) is not valid inside a collection expression (blocking, carried over from d06134c)

private static readonly HashSet<string> ControlTokens =
[
    with(StringComparer.OrdinalIgnoreCase),
    "arg",
    ...
];

This exact issue was already flagged on the prior revision as CS0103 (with is only valid as expr with { ... } on a record/struct — there's no method named with, and collection expressions have no established syntax for passing constructor arguments like a comparer). The latest PR comment asserts this is accepted because of SDK 10.0.401 with LangVersion=preview, but that claim isn't backed by a linked CI run or build log, and I wasn't able to execute a build myself in this review environment (the sandbox's approval gate blocked both Invoke-AgentDotNet.ps1 and a direct dotnet build here) to confirm it independently. I don't know of any C# collection-expression feature — shipped or previewed — that accepts a bare with(comparer) as the first bracketed element; the standard workaround (new HashSet<string>(StringComparer.OrdinalIgnoreCase) { ... }) has no such ambiguity and doesn't depend on unverified preview behavior. Please confirm this compiles with a green CI build before merge — if ModularPipelines.OptionsGenerator fails to build, none of the new tests in this PR can run despite the description's claim that "all 847 scraper tests pass."

2. UsageSynopsisParser.cs:1113-1124 — the '|' ambiguity guard now runs after colon-group parsing, not before (worth a look)

var content = TrimWrapper(normalizedToken).Trim();
var nestedTokens = Tokenize(content);
if (TryParseColonSeparatedOperands(
        nestedTokens, IsRequiredUsageToken(normalizedToken), positionIndex, phase, out arguments))
{
    return true;
}

if (!content.Contains('[') || content.Contains('|'))
{
    return false;
}

Previously, any bracketed group containing | bailed out here as ambiguous before any parsing was attempted. Now TryParseColonSeparatedOperands runs first and can return true for a group that contains both : and | (e.g. (RESOURCE|ALIAS : --location=LOCATION)), since Tokenize doesn't split on | and the colon-branch never checks for it. That reintroduces exactly the ambiguity the '|' guard was meant to prevent — for such a group TryParseColonSeparatedOperands would parse RESOURCE|ALIAS as a single operand token rather than rejecting the group as unparseable, producing an incorrect operand name/description instead of the previous safe no-op. None of the new fixtures combine alternation with a colon group, so this wouldn't currently be caught by tests. Consider moving (or duplicating) the content.Contains('|') check ahead of the TryParseColonSeparatedOperands call, or teaching that helper to reject tokens containing |.

Carried-over, already acknowledged (not new)

test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs still can't pass against the currently-committed generated src/ModularPipelines.Google code (no operand constructors/Location/Service properties yet, services still take optional Options? options = null). This is already tracked by the PR description and prior review as pending a separate regeneration run, so no new action needed from this review — just noting it's still true at 087a247 and remains a merge blocker until that lands, consistent with the repo's "current tool output is authoritative, never hand-edit generated options" rule.


Everything else in the parser/generator logic — the generic resource-operand parsing, the IsPositional split in validation, and the synopsis continuation-line joining — looks sound and appropriately scoped to the shared layer.

The collection-expression syntax is documented, not a method call or record with expression. Microsoft's C# language reference identifies C# 15 collection-expression arguments and includes this exact comparer form:

HashSet<string> set = [with(StringComparer.OrdinalIgnoreCase), "Hello", "HELLO", "hello"];

This repository explicitly sets LangVersion=preview in Directory.Build.props and pins SDK 10.0.401. Its guarded Release generator solution build succeeds with zero warnings/errors, and the current 856 scraper tests execute successfully. The claimed CS0103 does not apply to that configuration. A subsequent CI/review cycle still gates merge; no approval or CI check is being bypassed.

Pushed b0f54576aec6b35fae7b3dea1e7ee0c4c24cd3fb with both new parser review fixes.

  • Colon groups with ambiguous top-level alternatives now fail explicitly. Returning false from the nested-group parser alone would still allow the ordinary operand fallback, so this guard prevents silent guesses. Four regression cases failed before the fix. Explicitly nested operand alternatives and selector-value choices remain supported and tested.
  • Gcloud now consumes the shared SYNOPSIS parse, retains its text and operand metadata, and participates in shared required-alternative inference and operand coverage. Five traversal regressions failed before that fix. The addressed CodeRabbit thread is resolved after remote-head verification.
  • The repeated compiler concern is covered by Microsoft's documented collection-expression arguments and the successful pinned-SDK Release build. The full technical evidence is in comment 5665920810.

All 856 scraper tests pass. Release build: zero warnings/errors. Scoped severity-info formatting/verification, all 61 API baselines, and diff checks pass. Source fingerprint is 21b873df94ea981e52e7d1bb612d91647816eb7f342cec9d5be5181f9c4aa9ec.

The two generated-output threads remain unresolved and all 12 Google integration contracts remain enabled. Source prerequisites must land before fresh latest-main generation. No generated code was hand-edited and no cancelled generation or CI run was retried. A subsequent CI/review cycle is still required.

Created #5112 as the native source prerequisite of #4850. It will carry the complete source and generator regressions from b0f54576aec6b35fae7b3dea1e7ee0c4c24cd3fb onto current main, allowing source to land before the required fresh latest-main generation.

This PR retains all twelve Google integration contracts and its two unresolved output threads. No feature-branch generation is resumed and no generated file is hand-edited. The shared-synopsis source thread remains resolved by the confirmed fix push; subsequent CI/review still gates merging.

Code review

Reviewed at head b0f54576aec6b35fae7b3dea1e7ee0c4c24cd3fb. This is a solid, well-scoped fix: POSITIONAL ARGUMENTS now flows through the same shared CliArgumentGroup/ParseArgumentGroups machinery as flags, CliArgumentDefinition.IsPositional cleanly separates operands from switches, and UsageSynopsisParser learns the generic (OPERAND : --selector=VALUE) resource-group shape without any gcloud-specific hard-coding in the shared parser. Good fixture/unit test coverage for the new synopsis shapes.

Both issues raised on the prior revision (087a247) are fixed at this head:

  1. Ambiguous | across colon groupsTryParseNestedOperandGroup (UsageSynopsisParser.cs) now explicitly rejects a colon group when SplitTopLevelAlternatives finds more than one top-level alternative, before TryParseColonSeparatedOperands gets a chance to silently pick one side. SplitTopLevelAlternatives correctly tracks bracket/paren depth, so nested alternatives like (RESOURCE : --location=(REGION|ZONE)) and ((RESOURCE|ALIAS) : --location=LOCATION) are still parsed rather than rejected. Covered by Rejects_Ambiguous_Alternatives_Across_Colon_Groups and Colon_Groups_Preserve_Explicitly_Nested_Alternatives.
  2. CodeRabbit's colon-separator finding (operands after : getting swallowed unless they're all option selectors) — TryParseColonSeparatedOperands's new hasOnlySelectors check only treats the group as selector-only when every token after : is a recognized flag; otherwise it keeps operands on both sides ((SOURCE : DESTINATION) retains both Source and Destination). Covered by Colon_Groups_Preserve_Operands_After_The_Separator.

The with(StringComparer.OrdinalIgnoreCase) collection-expression syntax flagged as a compile error on the prior revision is not a bug. I fetched Microsoft's collection-expressions language reference directly: "Collection expression arguments" is a real, documented C# 15 feature — with(...) as the first element of a collection expression passes constructor/factory arguments (capacity, comparer, etc.), and the docs' own example is HashSet<string> set = [with(StringComparer.OrdinalIgnoreCase), "Hello", "HELLO", "hello"];, verbatim what's used here. This repo pins SDK 10.0.401 and sets LangVersion to preview in Directory.Build.props, exactly the combination needed to opt into a C# 15 preview feature under a .NET 10 SDK. I couldn't run an end-to-end build in this sandbox to double-confirm (same restriction the prior review hit), but the language feature itself checks out against the primary source, so I'm not carrying this forward as blocking.

Still outstanding, and this is the one thing keeping the PR from being merge-ready: the new test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs exercises operand constructors and Location/Service properties on GcloudKmsKeyringsDeleteOptions / GcloudMetastoreServicesMigrations...Options, but the currently-committed generated code (e.g. src/ModularPipelines.Google/Options/GcloudKmsKeyringsDeleteOptions.Generated.cs) is still an empty record with none of that — confirmed directly against the file on this head. This is already acknowledged in the PR description and CodeRabbit's earlier pass (regeneration queued separately, tracked under #4850), so it's not a new defect in the changed code — but per this repo's rule that generated options are never hand-edited and current tool output is authoritative, this PR needs the regenerated ModularPipelines.Google sources incorporated before the new tests (and the scraper fix they validate) can actually pass in CI.

No new design or architectural concerns beyond that: routing resource operands through the shared parser/validation instead of a gcloud-only patch is the right structural call, and I don't see a better alternative to suggest.

Review

This PR adds a single new test file, test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs, asserting new resource-argument behavior (required options parameter, positional resource rendering, Location/Service selector ordering, and validation of missing resources) for three gcloud commands. No other files are changed — the generator, scraper, and the corresponding *.Generated.cs sources under src/ModularPipelines.Google/Options and src/ModularPipelines.Google/Services are all unchanged from main.

That mismatch means the new tests don't currently pass against what's actually generated:

  • GcloudKmsKeyringsDeleteOptions, GcloudMetastoreServicesMigrationsDescribeOptions, and GcloudMetastoreServicesMigrationsDeleteOptions are still empty (or Async-only) records with no Location/Service properties and no (string) constructor. CreateOptions (line 60) does GetConstructor([typeof(string)])!.Invoke(...), and Short_Resource_Name_Renders_Before_Selector_Options (lines 38, 42) does GetProperty("Location")!/GetProperty("Service")! — both null-forgiving on reflection lookups that return null for these types today, so these tests throw NullReferenceException rather than exercising real behavior.
  • Resource_Service_Requires_Options (line 18) asserts parameter.IsOptional is false, but the corresponding DeleteAsync/DescribeAsync overloads in GcloudKmsKeyrings.Generated.cs and GcloudMetastoreServicesMigrations.Generated.cs still declare options = null, so IsOptional is true and the assertion fails.

I confirmed all of this directly against the unmodified generated sources on main (not just the diff), so it isn't a stale-comment artifact — the tests as committed will fail as soon as they run.

Per the repo's generated-code rule, the fix belongs in tools/ModularPipelines.OptionsGenerator (teaching it to parse the positional resource/selector metadata and make required resource args non-optional), followed by regenerating the affected *.Generated.cs files — not hand-editing the generated records to satisfy these tests. As it stands, this PR only adds assertions for a capability that hasn't landed yet; the generator/scraper change and its regenerated output need to be included (or this test file held back until they are) before this is mergeable.

Note: I saw a comment on this PR referencing a separate commit (ec417e66...) and workflow run said to contain the source fix and regeneration. That isn't reflected in this PR's current diff or head commit, so I can't verify or credit it from here — the fix needs to actually land in this PR (or a linked one) before it's mergeable.

Review

This PR's diff, as it stands at head 8ca2f7e, adds exactly one file — test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs (61 lines) — and nothing else. There are no changes to tools/ModularPipelines.OptionsGenerator, no regenerated *.Generated.cs files under src/ModularPipelines.Google. I confirmed this directly with gh pr diff 4956 and by diffing the relevant generated sources between main and pr-head/ (byte-identical).

That's a problem, because the new tests assert behavior that doesn't exist in the currently-committed generated code:

  • GcloudResourceArgumentTests.cs:60CreateOptions does optionsType.GetConstructor([typeof(string)])!.Invoke([resource]). None of the three target records (GcloudKmsKeyringsDeleteOptions, GcloudMetastoreServicesMigrationsDescribeOptions, GcloudMetastoreServicesMigrationsDeleteOptions) declare a single-string constructor — e.g. GcloudKmsKeyringsDeleteOptions.Generated.cs is still an empty record body. GetConstructor returns null, the ! doesn't suppress the runtime null-check, and .Invoke throws NullReferenceException. This breaks Fully_Qualified_Resource_Needs_No_Selector_Options, Short_Resource_Name_Renders_Before_Selector_Options (which also does GetProperty("Location")!/"Service"!, neither of which exist on these records), and Missing_Resource_Is_Rejected — 9 test cases total.
  • GcloudResourceArgumentTests.cs:15Resource_Service_Requires_Options asserts parameter.IsOptional is false, but GcloudKmsKeyrings.DeleteAsync and the two GcloudMetastoreServicesMigrations methods still declare Options? options = null, so IsOptional is true — the assertion fails for all three cases.

So this test file will fail/throw as soon as it runs in CI, against the code actually on this branch.

This isn't new — every review round on this PR (Codex, CodeRabbit, Greptile, and the prior github-actions passes at ec417e66, d06134c8, 087a2471, and b0f545766) flagged the same generated-output gap and was told a separate regeneration run would supply it. But at the most recent prior head (42ddee91) the actual generator/scraper diff had already disappeared from this PR entirely, leaving only the orphaned test file — and that's still true at the current head 8ca2f7e. Worth double-checking history here: it looks like whatever force-push/rebase produced 42ddee918ca2f7e dropped the tools/ModularPipelines.OptionsGenerator changes and regenerated src/ModularPipelines.Google output that earlier revisions of this same PR (e.g. b0f545766) did contain, rather than this being an intentional split.

Suggested approach: per this repo's own rule that generated options are authoritative and never hand-edited, this test file needs to land in the same commit/PR as (a) the generator fix in tools/ModularPipelines.OptionsGenerator and (b) the regenerated *.Generated.cs output it produces — not as a standalone assertion of not-yet-generated behavior. Restore the generator/scraper changes from the earlier revision (or re-run the regeneration workflow against the current source) and include the regenerated files in this PR before merge, so CI has real generated code to validate the new tests against. Landing a test-only commit that's guaranteed red against main's generated output isn't recoverable by anything in this diff alone.

Review

This PR's net diff against current main (1b1f0827) is exactly one file: test/ModularPipelines.Google.UnitTests/GcloudResourceArgumentTests.cs (62 lines added, 0 removed, 1 file changed per the PR API). No generator/scraper changes and no regenerated *.Generated.cs sources are included — I diffed the relevant files (GcloudKmsKeyringsDeleteOptions.Generated.cs, GcloudMetastoreServicesMigrationsDeleteOptions.Generated.cs, GcloudMetastoreServicesMigrationsDescribeOptions.Generated.cs, and the corresponding Services/*.Generated.cs) between main and pr-head/ directly and they are byte-identical.

That means the new tests assert behavior that doesn't exist in the generated code actually on this branch:

  • CreateOptions (GcloudResourceArgumentTests.cs:60-61) does optionsType.GetConstructor([typeof(string)])!.Invoke([resource]). None of the three target records declare a single-string constructor (searched the whole src/ModularPipelines.Google/Options tree — no generated options record anywhere has one). GetConstructor returns null, so .Invoke throws NullReferenceException at runtime — this breaks Fully_Qualified_Resource_Needs_No_Selector_Options, Short_Resource_Name_Renders_Before_Selector_Options (which also does GetProperty("Location")!/"Service"!, neither of which exist on these records), and Null_Resource_Is_Rejected_By_Constructor — 9 of the 11 parameterized cases.
  • Resource_Service_Requires_Options (line 18) asserts parameter.IsOptional is false, but GcloudKmsKeyrings.DeleteAsync and the two GcloudMetastoreServicesMigrations methods still declare options = null (optional), so this assertion fails for all three cases too.

So every test in this file will fail/throw as written, against the code actually on this branch.

This is not a new finding — CodeRabbit, Codex, and prior automated review passes on this same PR (at heads 8ca2f7e3, 42ddee91, b0f54576, and others) already flagged this identical generated-output gap, and it evidently was intentionally deferred (per the PR description: source prerequisite #5112 tracked separately, regeneration to follow). It remains unresolved at the current head 2069791b — the second commit here (test(google): assert missing resource constructor validation) only adds the test file itself, it doesn't restore the generator/scraper changes or regenerated sources that would make these assertions pass.

Suggested approach: per this repo's rule that generated options are authoritative and never hand-edited, this test file should land together with (a) the generator/scraper fix in tools/ModularPipelines.OptionsGenerator and (b) the regenerated *.Generated.cs output it produces for these gcloud commands — not as a standalone commit asserting not-yet-generated behavior. A test-only commit that is guaranteed to fail against main's current generated output isn't something later commits in this diff can fix; the regeneration needs to be included in this PR (or this PR held until it's ready) before it's mergeable.

No other design concerns: once the underlying generator change lands, routing resource operands through shared parsing/validation rather than a gcloud-specific patch is the right structural call.

Regenerate the service signatures before enforcing this contract.

Each supplied service method declares its options parameter with = null. Reflection therefore returns true for parameter.IsOptional. This assertion fails for all three cases.

Remove the default value in the generated service signatures if command options are now required. Otherwise, change this test to preserve the optional-parameter contract.

Generate the resource constructors before running these tests.

The supplied generated option records have no constructor that accepts string. GetConstructor([typeof(string)]) returns null, and CreateOptions throws NullReferenceException before reflection can wrap an ArgumentNullException.

Generate the resource operand constructors and their null validation with the pending generated output. Do not merge these tests before that output is included.

Generation update: https://github.com/thomhurst/ModularPipelines/actions/runs/35001246869/job/104490461965 failed with zero generated files. Source PR #5147 fixes the fatal option-only colon-group exception from #5145; its Release build and all 145 synopsis tests pass. Issue #5146 records 54 additional non-dispatch command parse failures from the same gcloud 585.0.0 run. No replacement Google PR was created. Generated-output findings remain open; no generated files were patched and coverage checks were not weakened. Fresh generation must run from main after the responsible source fixes land.

The missing generated-output blocker remains confirmed. Source PR #5147 now includes 6e86e36, fixing compound/forwarded operands, required operand groups, and inherited repeated-switch documentation. All 178 focused parser/resource tests and the Release generator build pass; broader nested-group execution hit the unchanged 2 GB guard and is deferred to CI. Fresh generation from main is still required before this runtime PR can pass. Issue #5146 remains open for full current-version coverage validation. Generated-output review threads stay open; no generated file was patched.
