fix(gcp): list only live commitments so the item cap counts live CUDs - #685
(*computeengine.Client).GetExistingCommitments lists every commitment in a project and region, including EXPIRED and CANCELLED CUDs, and the converter stops at 50 items (maxCommitmentsPages). In a region with more than 50 historical commitments, every call errors.
The platform is about to run a fail-closed recent-commitment check before each GCP purchase (LeanerCloud/cloud-commitments-platform#682, slice G1 of its reviewed plan). That check calls this method, so the cap would block purchases in mature regions permanently.
The list request now sets Filter: "(status != EXPIRED) (status != CANCELLED)" (AIP-160 syntax, ListRegionCommitmentsRequest.Filter), so the cap counts live commitments only. More than 50 live commitments still errors.
Callers checked
cloud-commitments-go: the only non-test caller is pkg/recfilter/dedupe.go:45. Its isRecentActiveCommitment already ignores expired and canceled commitments, so its behaviour is unchanged. Nothing in cmd/ calls it.
cloud-commitments-platform main: no non-test caller.
Tests
TestComputeEngineClient_GetExistingCommitments_ListsOnlyLive captures the request and asserts the exact Filter, project and region. It failed before the change (empty filter) and passes after it.
..._ItemCapStillErrors: 51 live items still return the cap error.
The fake service ignores Filter, so server-side filtering by the real API is unverified until the first live run. The test comment says so.
go build, go vet and go test ./... pass in providers/gcp, and so does pre-commit.
Commitment lookups now exclude commitments with expired or cancelled statuses, so results contain only commitments with other statuses. This filtering is applied when requesting commitments for a project and region.
GetExistingCommitments listed every regional commitment, including
EXPIRED and CANCELLED ones, and errors once more than 50 items come
back. A region with a long history would hit that cap every time, which
makes a fail-closed recent-commitment check block it permanently.
The list request now sends the filter "(status != EXPIRED) (status !=
CANCELLED)", so the cap applies to live CUDs only. The only in-repo
caller, the duplicate checker, already drops those states, so its
behavior does not change.
The test fake ignores Filter, so the tests assert the exact request
sent. Server-side filtering by the real API is unverified. Another test
keeps the cap error for more than 50 live items.

The GCP Compute Engine client now filters commitment list requests to exclude EXPIRED and CANCELLED statuses. Tests check the request’s project, region, and filter, and verify the iteration-cap error result.
Changes: Commitment list filtering
Layer / File(s)
Summary
Apply and verify the commitment list filter providers/gcp/services/computeengine/client.go, providers/gcp/services/computeengine/client_test.go
GetExistingCommitments sends an AIP-160 filter excluding EXPIRED and CANCELLED. Tests check the request fields and verify that exceeding the iteration cap returns an error with no results.
The filter change is mergeable after normal checks. Exactly 50 commitments still trigger a pre-existing cap error; address that boundary separately.

Read the 50th commitment before applying the cap.
collectCommitments checks pageIdx >= maxCommitmentsPages before it calls it.Next(). With exactly 50 live commitments, the loop reads 50 items and then returns the iteration-cap error at pageIdx 50. It never reads iterator.Done, so a region with exactly 50 live CUDs fails. The cap should reject only a 51st item. Move the cap check after it.Next() and before the append, so the iterator can finish normally at 50.

Add a test with exactly maxCommitmentsPages items. The current ItemCapStillErrors test uses 51 items only.

The behaviour is correct. One lint blocker: CI's Lint Code (providers/gcp) fails at this head on four new misspell findings, and the same lint on base 6731c7d is clean.
Blocking: misspell fails on lines this PR adds.
client.go:47:44 and :49:63: CANCELLED is flagged as a misspelling of CANCELED.
client_test.go:425:50: CANCELLED.
client_test.go:415:17: honours is flagged as a misspelling of honors.
CANCELLED is GCP's real enum spelling (computepb.Commitment_CANCELLED, compute v1.74.1), so the filter must keep it. The fix I suggest:
Build the filter from the SDK enum: "(status != " + computepb.Commitment_EXPIRED.String() + ") (status != " + computepb.Commitment_CANCELLED.String() + ")".
Assert the test against that same expression.
Reword the comment at :47 to not spell the word, and change honours to honors.
This also hardens the test. Today it compares two hand-typed literals, so a misspelling present in both would still pass, and the SDK names stop that.
Checked and holding:
Status coverage. compute v1.74.1 defines ACTIVE, CANCELLED, CREATING, EXPIRED, NOT_YET_ACTIVE and UNDEFINED_STATUS. The filter drops only EXPIRED and CANCELLED, so NOT_YET_ACTIVE (mapped to CommitmentStateQueued by gcpCommitmentState), CREATING (payment-pending) and ACTIVE are kept. Dedupe therefore still sees queued and in-flight CUDs.
Filter syntax. The Compute list API takes one parenthesised expression per condition, ANDed together, which is the form used. As the test's comment says, whether the live API honours the filter is unverified, because the mock ignores Filter.
The cap still fails closed.collectCommitments checks pageIdx >= maxCommitmentsPages before each Next() and returns an error with no list. Exactly 50 live items still errors rather than returning a short list (pre-existing). ItemCapStillErrors pins it.
Callers. None needs expired or cancelled commitments:
In this repo the only caller is pkg/recfilter/dedupe.go:98 (commitmentsForDedupe), used for duplicate detection.
Downstream, cloud-commitments-mcptools/search_dedupe.go:164-166 (dedupe) and cloud-commitments-clicmd/multi_service_fetch_all.go:128 use it. The cli call is AWS-only expiry sizing (--rebuy-window-days), which wants live, still-unexpired commitments.
The platform has no direct caller.
Evidence. On an export of 738d242 (providers/gcp via go.work), build and vet are clean and go test ./services/computeengine/... passes.
Fail on main.ListsOnlyLive fails on 6731c7d (Not equal on the filter).
Mutation probes, all killed:
drop the Filter field;
misspell it as CANCELED, which fails ListsOnlyLive;
disable the item cap, which fails ItemCapStillErrors.
I didn't write this. I checked it against the pinned SDK and every caller, and built and ran it locally on macOS.
The filter matches GCP's status values
In the pinned cloud.google.com/go/compute v1.74.1 (providers/gcp/go.mod:6), Commitment_Status is UNDEFINED_STATUS, ACTIVE, CANCELLED, CREATING, EXPIRED and NOT_YET_ACTIVE (apiv1/computepb/compute.pb.go:4781-4788). The SDK spells it CANCELLED, with a double L; CANCELED is not a value.
So (status != EXPIRED) (status != CANCELLED) drops exactly the two terminal states.
It keeps NOT_YET_ACTIVE and CREATING, which dedupe should count, because they are capacity already bought. It also keeps UNDEFINED_STATUS, which gcpCommitmentState passes through and logs.
Comment nit: the comment calls this "AIP-160 syntax". Parenthesized expressions with an implicit AND are the Compute Engine list-filter syntax, while AIP-160 uses AND. The expression itself is valid Compute syntax.
The cap still fails closed
collectCommitments returns nil with the iteration-cap error at item 50. It never returns a partial list.
TestComputeEngineClient_GetExistingCommitments_ItemCapStillErrors pins that with 51 live items.
Off-by-one, pre-existing, not blocking: the cap is checked before it.Next(), so a region with exactly 50 live commitments also errors, even though the 51st read would have ended the list. That fails closed, so it is only a spurious error.
Callers
In this repo, the only caller of GetExistingCommitments is pkg/recfilter/dedupe.go:98 (commitmentsForDedupe). The GCP client does not implement GetCoveringCommitments, so recfilter uses this list.
Outside this repo:
CLI (cmd/multi_service_helpers.go:683): the rebuy-window expiry check, which builds AWS service clients and wants expiring, still-live commitments.
MCP (tools/search_dedupe.go:162): a memoizing dedupe wrapper.
Neither needs expired or cancelled commitments, so live-only is correct for every caller.
On an error, recfilter returns the recs unfiltered with the error (dedupe.go:56-58). If the real API ever rejected this filter, the failure would be visible, not a silent dedupe miss.
Tests fail on main (reproduced)
At the head, I reversed only this PR's client.go hunk and kept the new tests:
ItemCapStillErrors passes on both trees, which is right for a regression guard.
At the head itself, go vet and go test ./... in providers/gcp pass. The test comment is honest that the mock ignores Filter, so the real API's handling of the expression is unverified.
The PR is BEHIND main, and git merge-tree onto main is clean (tree 3636502f). It needs a rebase or update before merge.
…w exactly 50 items
The filter string held the status names as literals, which the misspell
lint flags, and could drift from the API. It is now built from the
computepb Commitment status enum values, and the test asserts the same.
The item cap was checked before reading the next item, so a list of
exactly 50 commitments errored as if the cap had been passed. The check
now runs after the end-of-list check, so 50 items succeed and a 51st
still errors. A boundary test covers exactly 50 items; it failed with
the old order.

Lint: the filter is now built from the computepb Commitment status enum (Commitment_EXPIRED.String(), Commitment_CANCELLED.String()), and the test asserts the same values. "honours" is now "honors". golangci-lint reports 0 issues in services/computeengine.
Off-by-one (from ui-fix-2): the item cap ran before the end-of-list check, so exactly 50 commitments errored. The check now runs after it. New ..._ExactlyAtCapSucceeds test: it failed with the old order and passes now, and 51 items still error.
Delta reviews needed from claude-fleet and claude-ui-fix-2.
738d2422..e8879d377c381c3ab795a5bb363fdfc1d763f929 is one commit, e8879d37, touching providers/gcp/services/computeengine/client.go (+9/-6) and its test (+18/-2). Nothing else changed.
The filter is built from the SDK enum.fmt.Sprintf("(status != %s) (status != %s)", computepb.Commitment_EXPIRED.String(), computepb.Commitment_CANCELLED.String()) yields the same string as before: the pinned SDK's String() values are EXPIRED and CANCELLED. The //nolint:misspell notes on those two lines are justified, because CANCELLED is the SDK identifier. The comment's "AIP-160" claim is gone.
The boundary is now right. The cap check runs after it.Next() returns an item, not before it:
exactly 50 items reach iterator.Done and succeed;
a 51st item hits pageIdx >= maxCommitmentsPages and returns nil plus the cap error, so it still fails closed with no partial list.
One extra Next() call is the only cost.
The new boundary test fails without the fix (reproduced). I moved the cap check back above Next() in a scratch copy. ExactlyAtCapSucceedsfails there and ItemCapStillErrors still passes. At this head:
all six GetExistingCommitments tests pass;
go vet on the package is clean;
go test ./... in providers/gcp passes (macOS).
CI at this head:
Lint Code (providers/gcp) is SUCCESS, as are pkg, azure, pre-commit, integration and the security scans.
Lint Code (providers/aws) failed before linting anything. The golangci-lint action got Unexpected HTTP response: 504 downloading the linter (job 127293522353). That's an infrastructure flake: this PR touches no AWS code, and main is green. I'll re-run the job when the workflow finishes, since Unit Tests is still running.
Delta 738d242..e8879d3 is one commit touching providers/gcp/services/computeengine/client.go (+9/-6) and its test (+20/-2). Nothing outside those two files changed.
The lint blocker is fixed. The filter is now fmt.Sprintf("(status != %s) (status != %s)", computepb.Commitment_EXPIRED.String(), computepb.Commitment_CANCELLED.String()), with a scoped //nolint:misspell // SDK identifier. CI's Lint Code (providers/gcp) passes at this head, and golangci-lint on ./services/computeengine/... reports 0 issues locally. Because the filter now comes from the SDK enum, the names can't drift from what the API returns.
The boundary is correct. The cap check moved after the iterator.Done check:
exactly 50 live items return the full list (new ExactlyAtCapSucceeds);
a 51st item still fails closed with an error and a nil list (ItemCapStillErrors).
Probe: moving the check back before Next() fails ExactlyAtCapSucceeds.
CI. Unit, integration, pre-commit, and the pkg, azure, gcp and sanity lint jobs pass. Lint Code (providers/aws) failed on infrastructure: its annotations show "Unexpected HTTP response: 504" from the golangci-lint action download. This PR doesn't touch that module, so a re-run should clear it.
Locally, go test ./services/computeengine/... passes.
The rest of my 738d242 review still applies: the status coverage, the callers, and that live API acceptance of the filter is unverified.
Follow-up to my delta approval at e8879d3: I re-ran the flaked Lint Code (providers/aws) job (the 504 while downloading the linter), and it now passes. Unit Tests also passes, so every CI check at this head is green.
Only a merge.c8621078ba0b56b316e03b078061d4e8a89ce7dc is GitHub's update-branch merge. Its parents are e8879d37 (my approved head) and main's fd7b9f2a.
No resolution changes.git show --remerge-diff c8621078ba0b56b316e03b078061d4e8a89ce7dc is empty: the merge auto-resolved with no conflict hunks.
The PR's own change is untouched.git diff e8879d37 c8621078ba0b56b316e03b078061d4e8a89ce7dc -- providers/gcp/services/computeengine is empty, so my review of that change at e8879d37 stands.
CI at this head was still running when I checked. Merge only once it's green.
git show --remerge-diff c8621078 is empty. The merge has no conflict resolution or hand edits; every path merged as git would.
The PR's net change against main is unchanged:git diff fd7b9f2a c8621078 touches only providers/gcp/services/computeengine/client.go and its test. Those are the same changes I approved at e8879d3.
CI at this head was still running when I posted. In particular, the Lint Code (providers/aws) re-run (it previously hit a 504 downloading golangci-lint) has to come back green before merge.
Parents:c862107 (approved) and 0e67b94 (on origin/main).
No resolution:git show --remerge-diff 580b8f54 is empty, so the merge has no hand-resolved changes.
PR diff unchanged:git diff 0e67b945 580b8f54 is byte-identical to git diff fd7b9f2a c8621078. The PR's change against main is exactly what I approved.
No interaction with fix(aws): round fractional RI quantities down and scale their costs #682: what main brings in touches only providers/aws/... (the RI parser's rounding and scaling, plus EC2 tests) and the CHANGELOG. This PR touches only providers/gcp/services/computeengine. These are separate Go modules with no shared code path, so the AWS RI rounding cannot reach the GCP commitment filter.
Correction to my 580b8f5 note. Besides providers/aws/... and the CHANGELOG, main's side also changes pkg/ladder: the additive ObservedCommitmentRateCapability interface from #686. It adds only a new interface, and nothing in providers/gcp/services/computeengine implements or calls it, so there is still no interaction with this PR. The approval at 580b8f5 stands.
