* mini: state the format of a -tableBucket, do not infer it
A table bucket holds one format and that format decides which catalog can
serve it, but the flag only took names. The format came from
miniTableBucketFormat(): Iceberg whenever its port was up, Lance only when
it was not. So -tableBucket=vectors on a default mini quietly made an
ICEBERG bucket that the Lance namespace then refused every table in, and
the only way to get a Lance one was -s3.port.iceberg=0, which buys it by
deleting the other catalog. One flag, two meanings, decided by an unrelated
port.
Each entry is now name[:FORMAT], unsuffixed meaning ICEBERG as before:
weed mini -tableBucket=warehouse,vectors:LANCE
Both catalogs stay up and both buckets are reachable. A name whose format
has no endpoint here is skipped with a warning rather than created out of
reach, and the Iceberg-only S3_TABLE_BUCKET default-routing hint gets the
Iceberg names alone, without their suffixes.
* mini: do not reuse a table bucket that holds another format
CreateTableBucket answers BucketAlreadyExists on the name alone, so
-tableBucket=vectors against a bucket created as LANCE logged "already
exists" and moved on, and the Iceberg default-warehouse hint then pointed
at it. Every table create against that catalog fails with "table bucket
vectors holds LANCE tables", far from the flag that chose it.
ensureMiniTableBuckets now reads the format of a bucket it did not create,
warns when it is not the one asked for, and returns only the buckets that
hold what was requested. S3_TABLE_BUCKET is seeded from that list, so an
unprefixed Iceberg request falls back to its own default rather than
committing into a Lance bucket. A bucket predating declared formats reports
an empty one and still accepts either.
* mini: normalize S3_TABLE_BUCKET whichever way the spec arrived
The rewrite that keeps Lance names out of the Iceberg default warehouse only
ran when the flag supplied the spec. Set the variable directly, as the docker
quickstart does, and it reached the catalog untouched: S3_TABLE_BUCKET=
vectors:LANCE,warehouse made the unprefixed default the literal string
"vectors:LANCE", a bucket no lookup finds, while warehouse sat behind it.
The variable is both mini's input and the catalog's routing hint, so it is
now always rewritten from the buckets that came back holding Iceberg tables,
and unset when there are none rather than left pointing somewhere stale.
* mini: reuse a table bucket only when its format reads back
An ordinary S3 bucket wearing the name answers CreateTableBucket with the
same BucketAlreadyExists as a table bucket does, and the format lookup that
follows returned "" for a failed read exactly as it does for a bucket
predating declared formats. So -bucket=data -tableBucket=data reported
nothing and published data as the Iceberg default warehouse, where every
unprefixed request 404s on a bucket that is not a catalog.
The lookup now returns its error, and only a bucket that reads back as the
format asked for is reused. Anything else is left alone with a warning
naming why, rather than routed to and discovered later.
* feat(mini): add -bucket flag to pre-create an S3 bucket on startup
Lets users hand a pre-provisioned object store to clients/CI without a
post-start `weed shell s3.bucket.create` step. The flag is a no-op when
empty (default) and idempotent on subsequent starts.
* mini: bound bucket-creation RPCs with a timeout off miniClientsCtx
Address PR review feedback: derive the lookup/mkdir context from
miniClientsCtx() so Ctrl+C cancels the bucket RPCs, and cap with a 5s
timeout so a stalled filer cannot block the welcome message
indefinitely. Also wrap the DoMkdir error for parity with the lookup
path.
* mini: fall back to S3_BUCKET env var for -bucket
Mirrors the existing -s3.externalUrl / S3_EXTERNAL_URL pattern so
container/Kubernetes deployments can pre-create the bucket via env
without overriding the entrypoint command.
* docs(readme): lead weed mini quick start with credentials + bucket
Promote the one-line setup (env vars + bucket) so users get a
ready-to-use S3 endpoint without hopping between sections to find
credential and bucket setup.
* mini: accept comma-separated -bucket list
Lets a single startup pre-create multiple S3 buckets, e.g.
-bucket=bucket1,bucket2 (or S3_BUCKET=bucket1,bucket2). Names are
trimmed and deduped; per-bucket errors are logged and the loop continues
so one bad name does not block the rest.
* mini: add -tableBucket flag for pre-creating S3 Tables buckets
Mirrors -bucket but creates S3 Tables (Iceberg) buckets via
s3tables.Manager so users can hand the all-in-one binary a ready-to-use
table catalog without a follow-up weed shell call. Comma-separated, env
fallback to S3_TABLE_BUCKET, idempotent on restart, owned by the
DefaultAccountID placeholder.
* mini: use errors.Is for ErrNotFound check in bucket lookup
Matches the rest of the codebase (~20 call sites in weed/s3api). The
direct equality works today because LookupEntry returns ErrNotFound
unwrapped, but errors.Is future-proofs against any future wrapping.
