This PR is the first in a series aimed at closing
[#15109](https://github.com/coder/coder/issues/15109).
### Changes
- **Template Database Creation:**
`dbtestutil.Open` now has the ability to create a template database if
none is provided via `DB_FROM`. The template database’s name is derived
from a hash of the migration files, ensuring that it can be reused
across tests and is automatically updated whenever migrations change.
- **Optimized Database Handling:**
Previously, `dbtestutil.Open` would spin up a new container for each
test when `DB_FROM` was unset. Now, it first checks for an active
PostgreSQL instance on `localhost:5432`. If none is found, it creates a
single container that remains available for subsequent tests,
eliminating repeated container startups.
These changes address the long individual test times (10+ seconds)
reported by some users, likely due to the time Docker took to start and
complete migrations.
The failure condition being fixed is `w1` and `w2` could belong
to different users, organizations, and templates and still cause a
serializable failure if run concurrently. This is because the old query
did a `seq scan` on the `workspace_builds` table. Since that is the
table being updated, we really want to prevent that.
So before this would fail for any 2 workspaces. Now it only fails if
`w1` and `w2` are owned by the same user and organization.
* fix: avoid deleting peers on graceful close
- Fixes an issue where a coordinator deletes all
its peers on shutdown. This can cause disconnects
whenever a coderd is redeployed.
- Adds dbtestutil.WithTimezone(tz) to allow setting the timezone for a test database.
- Modifies our test database setup code to pick a consistently weird timezone for the database.
- Adds the facility randtz.Name() to pick a random timezone which is consistent across subtests (via sync.Once).
- Adds a linter rule to warn against setting the test database timezone to UTC.
* chore: add /v2 to import module path
go mod requires semantic versioning with versions greater than 1.x
This was a mechanical update by running:
```
go install github.com/marwan-at-work/mod/cmd/mod@latest
mod upgrade
```
Migrate generated files to import /v2
* Fix gen
* chore: rename store to dbmock for consistency
* chore: remove redundant dbtype package
This wasn't necessary and forked how we do DB types.
* chore: separate pubsub into a new package
This didn't need to be in database and was bloating it.
* feat: Implement view for workspace builds to include rbac info
* Removes the need to fetch the workspace to run an rbac check.
* chore: Use workspace build as RBAC object
* chore: Use golang templates instead of sqlc files
