This PR stubs out a Provider in the current /v3 module. It takes the ideas and best parts from #507 and attempts to bring them into the current module in a backwards-compatible way.

I may have been wrong, and cutting a /v4 was probably not the best approach. We can leave the /v4 as a future iteration based on feedback and one last (famous last words) cleanup of the package.

There will be notable differences between the Provider methods and the existing *Migration methods / direct functions, for example:

  • *Provider.Up()
  • *Migration.Up()
  • Up()

provider.go Outdated
// If opts is nil, the default options are used. See ProviderOptions for more information.
//
// Unless otherwise specified, all methods on Provider are safe for concurrent use.
func NewProvider(dialect Dialect, db *sql.DB, opts *ProviderOptions) (*Provider, error) {

@VojtechVitek wdyt about adding the Provider to the /v3 module instead of cutting an entire new major version /v4.

This was the plan for #507, but after a lot of thought, I think we can iterate on the Provider and extend it to support a bunch of features folks have been asking for.

This allows us to test the Store implementation in isolation from migrations.

There's both a short (sqlite3 with a temp test directory) and long (postgres container) test

I'm fairly happy with the ergonomics of this API.
