Laravel 7.10 Released

The Laravel team released v7.10.0 with cache lock support for the database driver, same-session ID request concurrency limiting and simplified truth-test assertions. Also, 7.10 includes quite a few new features, along with all the latest fixes and changes in the 7.x branch.

Truth-test Assertions with Just a Closure

Sjors Ottjes contributed a backward-compatible way of writing truth-test assertions with only a type-hinted closure:

// Before
Mail::assertQueued(SubpictureFinishedEmail::class, function (SubpictureFinishedEmail $email) use ($user) {
    return $email->user->id === $user->id;
});

// With 7.10+
Mail::assertQueued(function (SubpictureFinishedEmail $email) use ($user) {
    return $email->user->id === $user->id;
});

// or with a short closure

Mail::assertQueued(
  fn (SubpictureFinishedEmail $email) => $email->user->id === $user->id
);

Same-session ID Request Concurrency Limiting

Taylor Otwell contributed a long-requested feature around session concurrency:

This PR implements a long-requested feature (since basically the beginning of Laravel) for blocking concurrency requests from the same session until previous requests have finished. The basic use case being prevention of concurrent requests writing conflicting data to the session and data being lost.

Be sure to check out 7.x Same-session ID request concurrency limiting · Pull Request #32636 for full explanation and details.

Pagination Count as a Subquery

Taylor Otwell contributed Run pagination count as a subquery for group by and havings:

Maginating queries with groupBy or having statements is a long-standing issue in Laravel going back to the very beginning of the framework with literal dozens of raised issues…This solution was suggested @acasar years ago but I wrote it off at the time – but honestly I think it’s a lot better than what we have now so I’m bringing it up again for consideration.

A cast:make Command

Adrien Leloup contributed an artisan make:cast console command, which takes the name of a cast and saves it in app/Casts. It generates a class that implements the CastsAttributes interface.

Assert Database Count

Christoph Rumpel contributed a test assertion for database table counting:

$this->assertDatabaseCount('users', 50);

// A failure would look like:
// "Failed asserting that table [users] matches expected entries count of 50. Entries found: 1."

Auth Mode for the SMTP Mail Driver

@fragkp contributed an auth_mode SMTP driver option:

Sometimes, it’s useful to set explicit the auth_mode when you do not want to handle it by itself.

Possible values are: nullplainlogin or cram-md5.

Add hasNamedScope to the Base Model

Alex Bowers and Graham Campbell contributed separate PRs around model scopes.

First, Alex contributed a hasScope method on the base model:

The hasScope method cleans up checking if a scope exists in a dynamic way…The use case for this is requests containing an array of filters to be applied (via scopes), the code is more expressive with:

public function index(Request $request)
{
    $post = Post::query();

    foreach ($request->get('filters', []) as $filter) {
        if ($post->hasNamedScope($filter)) {
            $post->{$filter}();
        }
    }

    return $post->paginate();
}

Note that the method name changed to hasNamedScope in the final 7.10 release with Graham’s PR:

  1. The model is the source of truth for if a scope exists, but then the builder bypasses it to call the scope method. Instead, we should delegate to the model. This PR addresses this, and provides a reusable way to apply scopes.
  2. #32622 added hasScope, but the name hasNamedScope would be more consistent, since callScope expects a full on callable and callNamedScope expects the actual scope name.

Cache Lock Support for the Database Cache Driver

Taylor Otwell contributed cache lock support for the database driver inspired by Symfony’s Lock Component PDOStore. Check out the Pull Request #32639 for implementation details.
