refactor(server): one storage root, workspace as a key prefix - #246
Conversation
`EXTRALIT_STORAGE_URL` replaces `EXTRALIT_S3_ENDPOINT` and names the whole
root — endpoint, bucket and key prefix. Every workspace is a directory under
it (`{root}/{workspace}/{pdf,thumbnails,layout,schemas}/`), identical on disk
and on S3, instead of a bucket named after the workspace.
Why
Bucket-per-workspace made workspace names satisfy S3 bucket rules, required
`CreateBucket` (admin) credentials on the server's principal, and could not
target a shared bucket or a Cloudflare R2 account at all. It also kept
`aioboto3` alive for the one thing obstore cannot do.
The endpoint was read in four places with three disagreeing scheme sniffers:
`files.py` set `allow_http` from `not startswith("https://")`, `layout_store.py`
from `startswith("http://")`, `buckets.py` derived `use_ssl` separately. A
scheme-less `minio:9000` resolved differently depending on which one ran. All
four now consume one parsed `StorageRoot`.
What changed
- `parse_storage_url` accepts `file:///path` (default `~/.extralit/storage`),
`s3://bucket[/prefix]`, and `http(s)://host[:port]/bucket[/prefix]` for MinIO
and R2. A remote URL with no bucket segment fails at startup.
- Credentials are optional and come as a pair. Omitting them hands off to
obstore's own chain — IMDS, ECS task role, EKS IRSA — so an EC2/EKS
deployment needs no long-lived secret.
- `ObjectStorage.for_workspace(name)` returns a store already scoped to
`{prefix}/{workspace}`; `lance_uri`/`lance_storage_options` address the Lance
datasets the same way, so the layout store no longer builds its own URI.
- `contexts/buckets.py` and `aioboto3` are gone. Workspace creation touches
storage not at all; deletion empties the prefix. The `s3_bucket` and
`bucket_versioning` doctor checks collapse into one `storage` reachability
check with no autofix — there is nothing per-workspace left to create.
Breaking, pre-1.0 so renamed outright
- `EXTRALIT_S3_ENDPOINT` -> `EXTRALIT_STORAGE_URL`, now including the bucket.
`EXTRALIT_S3_SECURE` bound to no field and is deleted, as is the unprefixed
`S3_*` trio in devcontainer.json that `env_prefix` never read.
- `/api/v1/file{s}/{bucket}` -> `/{workspace}`; `ObjectMetadata.bucket_name` ->
`workspace`. The segment carried the workspace name already, so `Document.url`
rows and the exact-string dedupe are untouched and no migration is needed.
- `WorkspaceCreate.name` is now `^[a-z0-9][a-z0-9._-]{0,62}$`, validated on
creation only. It was `min_length=1`; bucket naming had been the de facto rule
and a key prefix imposes none.
Existing per-workspace buckets keep their objects. Moving one is
`mc mirror old-bucket/ root/prefix/<ws>/`; the docs say so and nothing runs it.
Verification
Server unit 1822 passed (3 pre-existing JWT/secret-key failures, identical on
main); search engine 134; OpenAPI drift gate; SDK 70; frontend 910.
MinIO end-to-end against `http://127.0.0.1:9000/extralit-e2e/dev`: put/get with
attributes, scoped listing, presign, `s3://extralit-e2e/dev/ws-a/layout` as the
Lance root, raw key `dev/ws-b/pdf/doc2`, and deleting `ws-a` leaving `ws-b`.
Follow-up, separate repo: `extralit-hf-space` still sets
`EXTRALIT_S3_ENDPOINT` in its README, CLAUDE.md and integration-test workflow,
and still imports `get_s3_client` (pending since #244).

📝 WalkthroughWalkthroughThe change replaces per-workspace S3 buckets with workspace-prefixed storage under a configurable local or remote storage root. It updates storage APIs, workspace lifecycle handling, file routes, metadata, validation, tests, workflows, and documentation. ChangesWorkspace-scoped storage migration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to This change moves workspace data into shared storage prefixes and changes deletion and URL handling, but the current head can delete workspace objects before a database rejection, allow crafted paths to escape local storage, expose storage credentials through the doctor response, and misresolve encoded local roots. These create concrete data-loss, security, and correctness risks, so the PR is not ready to merge until the affected handling is fixed. Sequence Diagram(s)sequenceDiagram

Review follow-ups to the storage-root change, plus one migration note it missed.
- `for_workspace` rejects names that could escape the root. `LocalStore` accepts
`..` in a prefix where `S3Store` rejects it outright, and the name arrives
straight from a URL path segment that an owner can set freely, so the guard has
to live here. It rejects separators and dot segments only, not the full
creation-time pattern: existing workspaces predate that pattern and must keep
working.
- `delete_workspace` deletes the row before the objects. A delete the DB refuses
(linked datasets -> 409) previously destroyed the workspace's files first and
then reported failure. Storage cleanup now runs only once the delete is
accepted, and a failure there leaks unreachable objects instead of losing
reachable ones. Un-skips three delete tests that had been failing with 500s.
- Credentials embedded in `EXTRALIT_STORAGE_URL` are rejected at startup, and the
error does not echo the URL. That keeps them out of the doctor's messages and
the unreachable-root log line, rather than redacting at each site.
- `parse_storage_url` percent-decodes `file://` paths. `Path.as_uri()` escapes
spaces and it builds the default, so a home directory with a space in it
resolved to a literal `%20`.
- `healthy()` creates a local root that does not exist yet. Nothing creates it
until the first workspace is written, so a fresh install reported its storage
unreachable.
- `delete_workspace_objects` evicts through a new `ObjectStorage.forget()`
instead of reaching into `_stores`.
- The CLI prints field errors and exits 1 instead of a pydantic traceback when
`--workspace` is given an invalid name.
Docs: local storage moved too, `{home}/<ws>/` -> `{home}/storage/<ws>/`, which
the bucket-only migration note did not cover — every disk-backed deployment
needs a `mv` or `EXTRALIT_STORAGE_URL=file://$EXTRALIT_HOME_PATH`. Also drop the
credentials from the deployment guide's *variables* list (they belong only in
the secrets list), spell out that production wants https, and say that restoring
a MinIO backup has to preserve each `{workspace}/...` key.
Server unit 1836 passed, same 3 pre-existing JWT/secret-key failures; drift gate
and SDK contract green.
- Removed direct reference to settings.storage_url in the workspace doctor checks. - Updated success message to indicate storage is reachable without specifying the URL. - Enhanced error message to instruct users to check the EXTRALIT_STORAGE_URL environment variable when storage is not reachable.
The six failing integration tests all reduce to one `ValidationError`: `ObjectMetadata.workspace` is required, and `extralitdev/extralit-hf-space:latest` — the published image those tests run against — still answers with `bucket_name`. The SDK ships on PyPI and the server is deployed separately, so a client that cannot read a server one release behind is broken for everyone who upgrades in the usual order, not just for CI. `workspace` now accepts either name on input via `AliasChoices`. The field, the attribute and everything serialized stay `workspace`; `bucket_name` is accepted, never emitted. Between `main` and this branch the only change to the file-response schema is that one field, so nothing else about the older payload needs handling. SDK unit suite: identical 16 failures before and after the change (all pre-existing, they want a live server); the new cases pass.
Committing the row before cleanup left a window: another owner could recreate the same name and upload, and the cleanup — keyed only by name — would then delete the new workspace's objects. The delete now runs uncommitted. A concurrent create of the same name blocks on the unique index until this transaction ends, so the name cannot be reused while the prefix is still being emptied. A storage failure rolls the delete back and returns 500 instead of dropping the row and leaking objects. The abort test asserts the status and the `autocommit=False` call: the row's survival is not observable through the test session, which shares one savepoint with the request, so a handler rollback also undoes the factory insert. Server unit 1837 passed, same 3 pre-existing failures.
EXTRALIT_STORAGE_URLreplacesEXTRALIT_S3_ENDPOINTand names the whole root — endpoint, bucket and key prefix. Every workspace becomes a directory under it, identical on disk and on S3:Net +581 / −1084 across 50 files.
Why
Bucket-per-workspace was a ceiling, not a layout. It forced workspace names to satisfy S3 bucket naming rules, required
CreateBucket— an admin-grade permission — on the server's principal, and could not target a shared bucket or a Cloudflare R2 account at all (R2 buckets are account-scoped and provisioned out of band). It also keptaioboto3alive purely for the one thing obstore cannot do.The endpoint was parsed in four places, three of them disagreeing.
contexts/files.pysetallow_httpfromnot endpoint.startswith("https://");contexts/ocr/layout_store.pyfromendpoint.startswith("http://");contexts/buckets.pyderiveduse_sslon its own. A scheme-lessminio:9000resolved toallow_http=Truein one and"false"in another. The "is this remote?" predicate —all([endpoint, key, secret])— was triplicated across the same three modules, which also meant credentials decided the backend.What changed
One grammar, one parser.
parse_storage_urlaccepts:file:///var/lib/extralit/storage~/.extralit/storage)http://minio:9000/extralit/prodhttps://<ACCT>.r2.cloudflarestorage.com/extralits3://extralit/prodA remote URL with no bucket segment is a startup error naming the fix, not a runtime 500. "Remote" is now URL scheme, not keys present.
Credentials became optional.
EXTRALIT_S3_ACCESS_KEY/_SECRET_KEYcome as a pair or not at all. Omitting them hands off to obstore's own chain — EC2 IMDSv2, ECS task role, EKS IRSA web identity — all of which the underlying Rustobject_storeresolves natively with auto-refresh. An EC2/EKS deployment needs no long-lived secret in its environment. (credential_process/SSO are not in that chain; the escape hatch isobstore.auth.boto3.Boto3CredentialProvider, noted in the config docs but not wired in — it can't reach LanceDB, which takes astorage_optionsdict rather than a callable.)Storage is backend-agnostic at the seam.
ObjectStorage.for_workspace(name)returns an obstore store already scoped to{prefix}/{workspace}; callers pass a workspace name and a key under it and never learn which backend they're on.lance_uri()/lance_storage_options()address the Lance datasets through the same root, solayout_store.pyno longer builds its own URI or its own credentials.contexts/buckets.pyandaioboto3are deleted. Workspace creation touches storage not at all — a prefix exists when the first object lands, which is how essentially every S3-backed application behaves. Deletion empties the prefix (obstore-native on both backends). Fourbuckets.createcall sites go with it:_app.py, both user-creation CLIs, and the create-workspace handler.Things worth a reviewer's attention
{bucket}→{workspace}is a pure rename, and that's what makes it free. The segment already carried the workspace name —FilePolicynamed its parameterworkspace_nameand resolvedis_member_of_workspace_nameagainst it. So authorization semantics are unchanged, everyDocument.urlrow already written stays valid, and the exact-string dedupe incontexts/imports.pystill matches. No DB migration.^[a-z0-9][a-z0-9._-]{0,62}$. They weremin_length=1; S3 bucket naming had been the de facto validator and a key prefix imposes none, somy ws/../xwould otherwise have been accepted into a URL path segment. Creation only — existing rows untouched.s3_bucket(autofix: create it) andbucket_versioning(autofix: suspend it) were both bucket-level and now have no per-workspace meaning. They collapse into onestoragereachability check withfixed=False— there is nothing left to fix per workspace.rq_worker_pooland the ES check are untouched.EXTRALIT_S3_SECUREbound to no field at all and is deleted from both env files. So is the unprefixedS3_ENDPOINT/S3_ACCESS_KEY/S3_SECRET_KEYtrio indevcontainer.json, whichenv_prefix = "EXTRALIT_"guaranteed was never read.extralit-server.ymlgains anaws s3 mbstep against the MinIO service.docker-compose.yamlwas already running LocalStore (it sets noEXTRALIT_S3_*); that's now the deliberate default rather than an accident.Breaking
Pre-1.0, so renamed outright rather than aliased:
