Alaister YoungandAlaister Young 7a399d7879 ci(studio): fetch enough history for paths-filter on push events (#49766)
Fixes the master-push failures in the Selfhosted Studio E2E workflow
(e.g. [this
run](https://github.com/supabase/supabase/actions/runs/33383940726))
where all shards die in ~30s at the `dorny/paths-filter` step with:

```
fatal: Not a valid object name <github.event.before>^{commit}
fatal: could not read Username for 'https://github.com': No such device or address
```

On push events, paths-filter diffs against `github.event.before` using
local git. With the default depth-1 checkout that commit usually isn't
present, so the action falls back to a `git fetch` — which runs
unauthenticated because we set `persist-credentials: false`, and GitHub
rejects unauthenticated git fetches from the runner IPs. Whether a job
passed depended on whether the runner's shared git cache happened to
contain the previous master tip, which is why shards fail
nondeterministically and re-runs partially recover.

**Changed:**
- `fetch-depth: 50` on the checkout preceding paths-filter in the three
workflows that run it on push (`studio-e2e-test`, `studio-unit-tests`,
`studio-docker-build`), so the comparison base is always fetched with
the checkout action's own credentials and no fallback fetch happens.
`persist-credentials: false` stays.

PR events are unaffected either way — paths-filter uses the GitHub API
there, not git.

## To test

- CI on this PR passes (PR path exercises the API code path)
- After merge, the next few master pushes run Selfhosted Studio E2E
without the paths-filter step failing

## Summary by CodeRabbit

* **Chores**
* Improved automated build, end-to-end test, and unit test workflows by
ensuring sufficient Git history is available for change detection.
  * Increased reliability of workflow runs triggered by code pushes.

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.
