Description

Adds computezone update to modify compute-zone metadata. The command supports --dry-run to preview the merged PUT request without writing, requires confirmation unless --yes is passed. It first reads the current compute zone from the backend so omitted fields are preserved before sending the replacement PUT request.

📝 Walkthrough

Walkthrough

The change adds computezone update support across the SDK and CLI. It validates metadata and coordinates, merges updates with existing values, preserves coordinate precision, supports dry-run previews, and documents the command.

Changes

Compute-zone update

Layer / File(s) Summary
Update contracts and validation
nvfleetint/common.go, nvfleetint/computezone.go
Adds compute-zone types, contact metadata, update request/result types, coordinate validators, JSON-number preservation, and contact mapping.
Merged update execution
nvfleetint/computezone.go, nvfleetint/computezone_test.go
Retrieves the current zone, merges requested fields, preserves unspecified values and coordinate precision, sends the PUT request, and validates failure cases.
Request preview generation
nvfleetint/preview.go, nvfleetint/preview_test.go
Adds request previews with normalized URLs and verifies that preview output matches issued update requests.
CLI command and user output
cmd/nvfleetint/computezone.go, cmd/nvfleetint/computezone_test.go, docs/cli.md
Registers computezone update, adds validation, confirmation, dry-run, text/JSON output, integration tests, and command documentation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 55c40

The update command can silently overwrite changes made concurrently, while its empty-value behavior and dry-run messaging do not match the documented or advertised behavior. These are bounded but actionable correctness and user-expectation issues that should be fixed or explicitly accepted before merging.

266-272: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

t.Fatalf is called from httptest handler goroutines in nvfleetint/computezone_test.go and cmd/nvfleetint/computezone_test.go. t.Fatalf must run on the test goroutine. From a server goroutine it calls runtime.Goexit on that goroutine, so the handler returns no response and the client observes an unrelated error or blocks. The shared root cause is one guard handler pattern copied into both tests.

  • nvfleetint/computezone_test.go#L266-L272: replace t.Fatalf in the guard handler with t.Errorf followed by return.
  • cmd/nvfleetint/computezone_test.go#L241-L243: replace t.Fatalf in the guard handler with t.Errorf followed by return.
♻️ Proposed fix for the guard handler

-		t.Fatalf("invalid coordinates should not reach the backend: %s %s", r.Method, r.URL.Path)

+	server := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+		t.Errorf("invalid coordinates should not reach the backend: %s %s", r.Method, r.URL.Path)

268-321: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider a single flag table instead of three parallel lists.

The eight update flag names appear in hasComputeZoneUpdateFlag, again in computeZoneUpdateOptionsFromFlags, and the same fields appear a third time in computeZoneUpdateSummary. A new flag must be added in three places. A missed entry produces a silent behavior gap, for example a flag that sets a value but never appears in the confirmation summary.

A single slice of {flagName, label, value *string, target **string} entries would drive all three functions.

Inline comments:
In `@cmd/nvfleetint/computezone.go`:
- Around line 355-364: The dry-run output in PreviewUpdateComputeZone
incorrectly claims that no request was sent; update the message to state that no
write request was sent, while preserving the existing method, URL, and body
preview output.

In `@docs/cli.md`:
- Around line 145-150: Update the computezone update documentation so the
empty-value clearing statement applies only to the contact and geo flags,
excluding --type, while keeping the complete list of supported update flags and
validation details unchanged.

In `@nvfleetint/computezone.go`:
- Around line 238-306: Document the last-write-wins behavior of
buildUpdateComputeZoneRequest and the related
UpdateComputeZone/PreviewUpdateComputeZone flow, noting that read-modify-write
updates and preview-then-update sequences can overwrite concurrent changes
because the API exposes no conditional-update mechanism. Add the same warning to
docs/cli.md; do not add ETag, version, or If-Match handling unless the API
contract provides it.
