Francesco SansalvadoreandClaude Opus 5 c8a9a7a630 fix(studio): correct storage explorer listing pagination and column scroll (#50476)
| | PR | Base | Branch |
| --- | --- | --- | --- |
| 1 | **this PR** | `master` | pre-existing correctness fixes |
| 2 | #50413 | `fix/storage-explorer-listing-and-scroll` |
`?path`/`?preview` deep-linking + copy row actions |

| 4 | #50480 | `test/storage-deep-link-e2e` | copy path / copy link row
actions |

To read the whole change in one view:

```bash
git diff master...test/storage-deep-link-e2e -- apps/studio e2e
```

## What is the current behavior?

Four independent bugs in the storage explorer, all pre-existing on
`master`:

- `hasMoreItems` is derived from the *formatted* listing, but
`formatFolderItems` drops the `.emptyFolderPlaceholder` — so a full page
can format to `LIMIT - 1` and stop pagination a page early.
- A failed listing is indistinguishable from an empty folder, so a fetch
error reads as "this folder has nothing in it".
- `fetchFoldersByPath` commits its result against whichever bucket is
selected when the requests resolve. Switching buckets mid-flight files
the old bucket's items under the new bucket's name — and because
`columns[0].name` then matches, nothing downstream notices and
refetches.
- The horizontal auto-scroll never runs its guard (`if
(fileExplorerRef)` is always truthy), scrolls relatively so repeated
runs drift, and depends on the `columns` array identity — so a
background refetch yanks the view back to the right. It also scrolls in
list view, where there is nothing to scroll.

## What is the new behavior?

Each of the above is fixed at its source. Pagination and the
exhaustiveness check now compare the raw page length; listings carry an
`isComplete` flag; `fetchFoldersByPath` captures the bucket id at entry
and discards a stale result; the scroll is absolute, guarded, keyed on
`columns.length`, and skipped in list view.

Two new test files cover the parts that were silently wrong before:
`state/storage-explorer.test.ts` (MSW, the bucket race) and
`FileExplorer.test.tsx` (scroll geometry, with the container's layout
defined by hand since jsdom reports everything as zero-sized). Both were
checked by reverting the fix and confirming they fail.

## Additional context

`fetchFoldersByPath` also starts returning `{ missingPaths }` here.
Nothing reads it yet — the first consumer is in PR 2 — but it shares a
hunk with the `isComplete` work, so separating it would mean two PRs
editing the same lines. It is backward-compatible: all three existing
call sites ignore the return value.

## Summary by CodeRabbit

## Bug Fixes

- Improved Storage Explorer column-view scrolling so the newest column
remains visible, including when the preview pane opens.
- Prevented folder results from a previously selected bucket from
appearing after switching buckets during loading.
- Improved handling of incomplete or partial folder listings to avoid
incorrectly treating failed results as empty folders.
- Preserved the correct scroll position when using list view.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Envoy is a cloud-native, high-performance edge and service proxy.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
