Bug: `adc sync` fails when deleting a consumer with credentials by pazars · Pull Request #632 · api7/adc

pazars · 2026-11-09T11:19:28Z

Description

Current Behavior

When adc sync removes a consumer that has credentials, the APISIX backend deletes the consumer first and then tries to delete each of its credentials. APISIX already removed those credentials together with the consumer, so every credential DELETE returns 404 Key not found and the sync exits with an error:

[APISIX] › ▶  start     Delete consumer: "jack"
[APISIX] › ✔  success   Delete consumer: "jack"
[APISIX] › ▶  start     Delete consumer_credential: "jwt"
[APISIX] › ✔  success   Delete consumer_credential: "jwt"
[ADC] › ✖  error     Sync configuration
[ADC] › ✖  fatal     Error: DELETE http://127.0.0.1:19180/apisix/admin/consumers/jack/credentials/eef397878595dd0eec2589d9d172d1c88dc4f6d4, responded with status 404 Not Found, response body: {"message":"Key not found"}

Expected Behavior

adc sync removes the consumer and its credentials and exits without an error.

Steps to Reproduce

Create a consumer with a credential:

# with-consumer.yaml
consumers:
  - username: jack
    credentials:
      - name: jwt
        type: key-auth
        config:
          key: jack-key

adc sync -f with-consumer.yaml

Remove the consumer from the configuration:

# without-consumer.yaml
consumers: []

adc sync -f without-consumer.yaml

The consumer delete succeeds. The following credential delete fails with 404 Key not found and adc sync exits with an error.

The diff shows the order without touching the gateway:

adc diff -f without-consumer.yaml

The consumer delete event is listed before the consumer_credential delete event.

Environment

APISIX version: 3.18.0
ADC version: 0.31.0
OS: Linux 7.2.13-200.fc44.x86_64 (x86_64 GNU/Linux)
Backend: apisix (Admin API)

Changes

The APISIX backend (TS and Rust) now drops a credential delete when its consumer is deleted in the same sync, since APISIX already removes the credentials with the consumer. This follows the same filter the API7 backend got in #343. The differ's event order is unchanged.

Tests: APISIX e2e cases that sync Differ.diff output removing a consumer with credentials (TS) or the differ's event order (Rust), plus a Rust unit test for the filter. The new e2e cases fail on main with the 404 above and pass with this change (APISIX 3.18).

Summary by CodeRabbit

Bug Fixes
- Improved synchronization when consumers and their credentials are deleted together. Credential deletions for a consumer being removed are now handled without interfering with the same update, while independent credential deletions continue to apply.
- Added coverage for synchronization scenarios involving multiple consumers and credentials, including confirmation that credentials on a retained consumer remain available.

Walkthrough

Both APISIX operators now filter credential-delete events when the parent consumer is also deleted in the same batch. Unit and end-to-end tests cover event filtering and the resulting consumer and credential state.

Changes: Consumer credential deletion synchronization

Layer / File(s)	Summary
Filter cascaded credential deletions `libs/backend-apisix/src/operator.ts`, `rust/crates/adc-backend-apisix/src/operator.rs`, `libs/differ/src/differv3.ts`, `rust/crates/adc-backend-apisix/tests/e2e_resource_consumer.rs`	Both operators remove credential-delete events whose parent consumer is deleted in the same batch. The Rust unit test verifies that unrelated deletes and other events remain. The differ comment describes credential deletion behavior for standalone backends and the Admin API.
Validate consumer and credential synchronization `libs/backend-apisix/e2e/resources/consumer.e2e-spec.ts`, `rust/crates/adc-backend-apisix/tests/e2e_resource_consumer.rs`	APISIX 3.11.0+ end-to-end tests exercise consumer deletion alongside credential changes, then verify the remaining consumers and credentials. The Rust integration test is ignored.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: Low · up to 04a7a

The change prevents redundant credential deletions after successful consumer removal. If consumer removal fails, both backends omit the skipped credential deletions from their failure reports. This is a bounded reporting gap suitable for owner-aware follow-up.

Full details: Title check

Explanation

The title names the bug and the affected command, which matches the main change. The change makes the APISIX TypeScript and Rust backends skip a credential delete when its consumer is deleted in the same sync, because APISIX already removes those credentials and later deletes return 404 Key not found. The title is specific and concise, and a teammate scanning history would understand the primary change. The title does not mention the fix mechanism, but it is not required to cover every detail.

Full details: Security Check

Explanation

No security issue was found in the changed code. The APISIX filters skip credential deletes only when the same batch deletes their parent consumer. The differ assigns the consumer ID to credential subevents. 1. Sensitive data exposure: No issues found. 2. Unencrypted database secrets: No issues found. 3. Authorization bypass: No issues found. 4. Cross-resource access: No issues found. 5. TLS and cryptography: No issues found. 6. Resource isolation: No issues found. 7. Secret reference resolution: No issues found.

Full details: E2e Test Quality Review

Explanation

⚠️ Major: The new TypeScript E2E flow has hidden test-order dependencies (libs/backend-apisix/e2e/resources/consumer.e2e-spec.ts:127-170). The delete test relies on the create test, and the dump tests rely on earlier tests. If the delete test runs alone against an empty backend, it creates the retained consumer instead of testing deletion and can pass.

Resolution

Put the full create, delete, and verification flow in one test, or give each test explicit setup and cleanup. Ensure the deletion test verifies that its input includes the intended delete events.

Report credential deletes when the consumer delete fails.

If the consumer delete fails without removing the consumer, the credential deletes remain unattempted and have no result entries. The server therefore omits them from its failure report. Emit failed results for those credential deletes when the consumer delete fails.

Report credentials skipped after a failed consumer deletion.
