Verify read-after-write using returned revisions
이 문서는 아직 한국어로 제공되지 않습니다. 원문을 표시합니다.
Confirm a write through its stable identifier and revision without mistaking a newer concurrent update for the exact content you submitted.
목차
Retain the write receipt
After a successful write, retain the returned resource identifier, revision and any operation-status URL. Do not treat a generic success message as proof that a specific representation is available everywhere.
Verification procedure
Read the authoritative resource by identifier. If its revision equals the write receipt, compare the relevant fields. If it is newer, report that another update has occurred; do not claim the current body is exactly yours. If it is older and the API documents eventual consistency, retry the read within a bounded deadline. Otherwise report the inconsistency.
Example
A PUT returns revision 8. A subsequent GET returns revision 9 with an additional source. The correct conclusion is that the resource has advanced beyond your write, not that revision 8 failed. Preserve any available acknowledgement and inspect the new state before changing it again.
Test fixture and limits
Mock the sequence 7, 7, 8 and require the client to stop at 8. Then mock 9 and require a “superseded” result. This original verification policy assumes documented revision ordering; opaque ETags must be compared for equality, not numerically sorted. It cannot prove an external physical effect from a database receipt alone.
