Overview

HttpKernel Component

The HttpKernel component provides a structured process for converting a Request into a Response by making use of the EventDispatcher component. It's flexible enough to create full-stack frameworks, micro-frameworks or advanced CMS systems like Drupal.

Sponsor

The HttpKernel component for Symfony 5.4/6.0 is backed by Les-Tilleuls.coop.

    Symfony browser-kit in require dependencies

    In Client.php there's browser kit used use Symfony\Component\BrowserKit

    However, it is not explicitely required by this lib and I think it should be. I think it's a sub dependency and therefore shouldn't be necessary to require it as direct dependency in my project.

    What are your thoughts?

    catch \Throwable instead of \Exception

    Catching \Throwable instead of \Exception can be more versatile. In case of \TypeError kernel won't catch it with possibility to handle it with kernel.exception listener.

  • Fix Apache's mod_expires Cache-Control issue

    Fix Apache's mod_expires Cache-Control issue

    Apaches's mod_expires is a widely used module to set HTTP caching headers. It allows you to set a default cache lifetime as well as lifetimes by mime_type.

    When an application server has set a Cache-Control header, mod_expires ignores this and sets its own, resulting in duplicate Cache-Control headers and conflicting information. It does this unless the application server sets an Expires header, in which case mod_expires does nothing. This is documented on the link above:

    When the Expires header is already part of the response generated by the server, for example when generated by a CGI script or proxied from an origin server, this module does not change or add an Expires or Cache-Control header.

    Symfony automatically sets a Cache-Control header if a session exists. This patch ensures it's respected by mod_expires.

    Example 1

    With the following Apache config:

    <IfModule mod_expires.c>
    ExpiresActive on
    ExpiresDefault                                      "access plus 1 month"
</IfModule>

    The HTTP response headers are:

  • Added statusCode to parent::_contruct

    Added statusCode to parent::_contruct

    I ran into a case where I got a InvalidArgumentException(code: 0) with the message: The HTTP status code "0" is not valid while building the response for an exception of the type HttpException.

    As you can see, at the moment, the parent is getting the $code variable, which is not set. The thing that is being used is $statusCode.

    This leads to the following:

    $exception->getCode results in 0 $exception->getStatusCode results in a http-status code, like 404.

    Expected was the following:

    $exception->getCode results in 404 $exception->getStatusCode results 404.

    This problem only happens when people have a custom exception handler that expects that the inherited getCode method form the extended parent Exception class can be called...which in this case is being set to 0, even though it is a HttpException.

    So my proposed solution is to change the constructor from:

        public function __construct(int $statusCode, string $message = null, \Throwable $previous = null, array $headers = [], ?int $code = 0)
    {
        $this->statusCode = $statusCode;
        $this->headers = $headers;

        parent::__construct($message, $code, $previous);
    }

    to:

        public function __construct(int $statusCode, string $message = null, \Throwable $previous = null, array $headers = [], ?int $code = 0)
    {
        $this->statusCode = $statusCode;
        $this->headers = $headers;

        parent::__construct($message, $statusCode, $previous);
    }

  • Allow user to set the project dir

    Allow user to set the project dir

    Currently, the project directory is defined by the location of the composer.json file.

    That file is not required in production, which therefore breaks the method getProjectDir (who sends back null). The offered solution, while working, requires the developer to implement it, and uses inheritance override, while a more aesthetic solution could be used.

    This does not fix the behaviour, but allows the developer to pass the project dir as a parameter.

    While this solution does not include BC break or anything, it is important to notice that it includes an optional parameter.

    Object instantiation in the framework bundle recipe could be updated as follow (in another PR):

    $kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG']);

    $kernel = new Kernel($_SERVER['APP_ENV'], (bool) $_SERVER['APP_DEBUG'], dirname(__DIR__));

    Remove _path from query parameters when fragment is a subrequest and request attributes are already set

    Without removing the _path query parameter, ESI handled through an actual proxy (Varnish, for example) behave differently than ESI handled when the proxy is not available (and thus the fragment is a subrequest instead of a master request).

    Update HttpCache.php

    simplification... I guess the original Author was trying to pursue something like a martingale (doubling) strategy (or in this case the increment over a constant factor) but well ... he did not. Instead a constant wait time was introduced, which means the wait is simply executed a 100 times over (in the worst case). And so I do not see a need for "5000000" and "+= 50000" to remain here.
