app/models is gone. Laravel 5 came out at the start of the month, and of everything in the release the folder I notice most is the one that no longer exists. The old skeleton had app/models and app/controllers. You knew where things go because the framework told you. Laravel 5 removes that. There is app/, it maps to the App namespace through PSR-4, and inside it you organize classes however you want. ...
require APPPATH.'../vendor/autoload.php'; One line in bootstrap.php. This month it became the whole strategy for a project we decided to keep on Kohana. The framework is quiet, the project is alive. These two facts have to coexist somehow. The plan: nothing new gets written the Kohana way. New dependencies come through Composer, and Kohana’s autoloader and Composer’s autoloader live together fine. First candidate was the HTTP client. We talk to two external APIs, and the code around Request_Client_External was not pretty. Guzzle is better in every way. But Guzzle does not spread through the codebase. There is an interface: ...
$link = 'https://'.$_SERVER['HTTP_HOST'].'/reset/'.$token; I wrote this line. More than once. It builds the link for a password reset email, and it looks like it reads something about the server. It does not. Host comes from the client, same as any other header. Kohana 3.3.4 shipped this month with a fix around exactly this, and the topic is bigger than one framework. The attack is short. Someone requests a password reset for your email address and puts his own domain into the Host header. The application trusts the header, builds the link, sends it. You receive a real email from a real site with a link to evil.example and your real token in the path. You click. He collects the token. Host header poisoning, and no framework protects you from it out of the box. ...
dump() instead of var_dump(). Symfony 2.6 came out at the end of November, and this is the visible gift: VarDumper. Collapsible output, clickable class names, works inside the toolbar. A small thing, used fifty times a day. Tools like this improve life more than big features do. But the important story in 2.6 is not a feature. The release notes read like a preparation checklist for Symfony 3: deprecations, everywhere. ...
One AppBundle. That is the line in the official Symfony Best Practices book I read twice. For years the answer to “how many bundles” was “as many as you have features”, and here the framework’s own book says: one. The book came out this autumn. Worth reading even if you are not on Symfony, because the interesting part is the change of tone. The old Symfony way: everything is a bundle. Your application is bundles, reusable, configurable, with their own extensions and semantic configuration. Very flexible. And for a normal business application, mostly ceremony. You write a configuration class for code that will never leave this one project. I wrote such classes. Three of them. None was ever reused. ...
/_profiler on a live site. Type it after any Symfony domain and sometimes it answers. This autumn the story went around, and I will not retell it. The lesson is bigger than one framework. Think what a profiler actually stores. Every SQL query with parameters. Cookies and session data. Routes, controller names, request headers. Sometimes config values. A full X-ray of your application, nicely formatted, with search. Now count how many sites have /_profiler or a debugbar open to the world because someone deployed with app_dev.php, or left debug = true in the production config. Not a rare exotic mistake. I saw it. I made it once, on a staging server that stayed reachable from outside longer than anyone planned. ...
A nightly cron failed silently for two days. That was our PHP 5.6 upgrade. 5.6 is out since the end of August, and we moved one production project this month. The syntax part is pleasant and minor. Variadics: function log_all($level, ...$messages) { } Argument unpacking with ...$args on the call side. Constant expressions in defaults. use function for importing functions. All nice. None of it changes your architecture. You will use variadics maybe twice a year and be happy both times. ...
120 lines in one action. Order confirmation: load the order, charge the card, send the email, render the page. It ran fine for a year. Then a console script needed the same operation, and the action turned out to be glued to SMTP, to the database and to the HTTP request. All at once. Symfony people talk about dependency injection so much it sounds like religion. It is one simple idea: a class receives its dependencies and does not create them. ...
1.8 seconds for one registration request. I put a timer around it on a project last month. 1.5 of those seconds was the welcome email going out over SMTP. The user waits almost two seconds and looks at a spinner, for a handshake with a mail server he will never hear about. Laravel 4.2 makes the fix one line: Queue::push('SendWelcomeEmail', array('user_id' => $user->id)); The controller returns in 300 ms. A worker picks the job up and sends the email. php artisan queue:listen to start, beanstalkd or Redis behind it, the failed_jobs table for jobs that died. ...
One line in bootstrap.php, above Kohana::init(): require DOCROOT.'vendor/autoload.php'; That is the whole integration. Kohana keeps its modules and its underscore autoloader. Composer brings Packagist. Two autoloaders in one process, and they do not collide: Composer packages use namespaces, Kohana classes have underscores, the lookups never meet. { "require": { "guzzlehttp/guzzle": "~5.0" } } This setup runs in production on one of my projects for a few months. Zero problems from the autoloading side. The problems, when they came, were from me. ...
