* s3: give a versioned metadata-only copy its own chunks A self-copy that only rewrites metadata clones the source entry, chunk fids and all, and writes the clone back. With no versioning that is exactly right: the clone replaces the entry it came from, so one entry owns the needles the whole time. Under versioning the clone lands in a new .versions/ file and the source stays live, and nothing refcounts a plain shared chunk list -- deleting either version (a NoncurrentVersionExpiration rule, say) frees needles the other still points at, and the next vacuum makes that permanent. rclone hits this on every upload, since it stamps mtime with exactly this copy. Take the metadata-only path only where the write replaces the entry it read: the bare key of a bucket without versioning. Versioned, suspended, and versionId-pinned copies fall through to the regular copy path, which gives the destination its own chunks. * s3: reencrypt a versioned SSE-KMS key rotation instead of reusing the chunks A same-object copy that changes the KMS key id hands the source chunks straight back, on the assumption that the copy overwrites the entry they came from. A versioned bucket writes a new version beside the source instead, so the two end up sharing needles that nothing refcounts, and deleting either one frees the other's data. Reuse the chunks only when the destination really is the source entry; otherwise fall through to the reencrypt path, which also gives the new version the key it asked for rather than leaving it on the old one. * s3: make one predicate decide whether a copy replaces its source The metadata-only branch and the key-rotation strategy both answer the same question -- does this copy write back to the entry it read -- so let them share one predicate instead of pairing a same-destination check with it separately at each site. * test(s3): fail the copy regression tests when the vacuum does not run The helper swallowed a failed or non-200 request to the master, so a vacuum that never ran turned both chunk-ownership assertions into no-ops: the tombstoned needles were still readable and the surviving version looked fine either way. Require the endpoint, the request, and a 200. * ci(s3): run every versioning test in the regression gate The gate named the tests it wanted, so a new regression test sat there uncovered until someone remembered this file -- it fooled me into thinking two tests added in this PR never ran anywhere, when the comprehensive job had them all along. Invert it: run everything, and name a test only to keep it out. The delete job beside this one already works that way, and the suite costs about two minutes. Only the pagination stress tests are excluded; they build 1500+ versions, skip themselves without ENABLE_STRESS_TESTS, and have their own make target. Go's regexp has no negation, so the pattern is still assembled from a listing, the way the volume-server integration workflow does it. Note the trailing $$: make eats a lone trailing $ and takes the anchor with it.
