Stream an image from Symfony controller

When sending an image/file from a Symfony controller you would usually read the file from filesystem.
This you can do by passing the file path to the BinaryFileResponse class and return it in the controller, as described in the docs:
https://symfony.com/doc/current/components/http_foundation.html#serving-files

use Symfony\Component\HttpFoundation\BinaryFileResponse;

$file = 'path/to/file.txt';
$response = new BinaryFileResponse($file);Code language: PHP (php)

But in some cases you might want to create an image dynamically and return it directly from the controller without storing it on the filesystem.
So you can create your image with the GD library and directly stream the GDImage object from the symfony controller with the StreamedResponse class.

Doctrine migrations and Postgis

Using Postgres with the Postgis extension to integrate GeoData / GIS functionality in your project is not natively supported by Doctrine and Doctrine migrations.

First you have to add the extension to Postgres, even if you use the Postgis docker image like postgis/postgis:14-3.3-alpine.

So add this SQL statement to the up method of your first migration:
$this->addSql('CREATE EXTENSION IF NOT EXISTS postgis;');

and the DROP statement for the extension to the down method:
$this->addSql('DROP EXTENSION postgis;');

Now, when using Doctrine with Postgres and Postgis extension, migrations still behave a bit odd and try to remove Sequences created by Postgis, because Doctrine migrations does not take Postgis extension’ s built-in Sequences into account.

Symfony deprecation log channel

Are you annoyed of too many deprecation warnings in you logs of your symfony app?
Probably yes because it is really a lot of noise.
However deprecation logs are still useful to ensure future compatibility of your app.

So since version 5.1 symfony will log deprecations to a dedicated log channel when it exists and ships with this monolog config:

monolog:
    channels:
        - deprecation # Deprecations are logged in the dedicated "deprecation" channel when it existsCode language: PHP (php)

This is added already in the recipe and ships when installing symfony.

Ok, but the handler for this deprecation channel is not configured, so you have to do this yourself.
How? Add this to your monolog config:

Silverstripe file credits addon

I released a new small Addon (or Module or Plugin) for SilverStripe CMS which adds a credits tab to the FileAdmin, so you can add f.e. the copyright holder of the image or any file.

Useful when you need to name credits, licence and source links for any asset used on your SilverStripe site.

Disable SilverStripe deprecation warnings in PHP8.1

Since SilverStripe 4.10 is not yet fully ready for PHP8.1 you wil receive quite some deprecation warnings in dev mode when you are brave and run it nonetheless on PHP8.1.

Deprecated: SilverStripe\Config\Collections\MemoryConfigCollection implements the Serializable interface, which is deprecated. Implement __serialize() and __unserialize() instead (or in addition, if support for old PHP versions is necessary) in /var/www/html/vendor/silverstripe/config/src/Collections/MemoryConfigCollection.php on line 13

Unfortunatly we can’t control the error_reporting from SilverStripe since it is set in the kernel of the framework.
So we are forced to hack the Kernel which is rather unfortunate.

In the SilverStripe Slack channel someone proposed to use composer-patch which will apply a patch to a given vendor dependency during composer install.
This is quite cool because you don’t need to fork the dependency and take care of getting upstream changes.

So i went this path down and it looks like in this gist:

Class “Psr\Log\Test\TestLogger” not found

The psr/log package used to have not only the Interface for PSR-3 Logger, but also actual implementations of the interface like the TestLogger.
The TestLogger could be used as mock for any PSR-3 Logger in your test cases.

However from v3 the TestLogger was removed, so that the psr/log package would focus solely on the Interface.

If you used the TestLogger in your project and you or some of your dependencies upgraded psr/log to >= v3 you most likely saw this error:

Class "Psr\Log\Test\TestLogger" not found

Filter a csv file with nodejs streams

So we have a CSV file with a member list and we want to filter all empty emails.

FirstName,LastName,Email
Max,Mustermann,max@mustermann.de
Maxi,Hasnoemail,

With nodejs streams this is almost a one liner.

We will use the csv package from the CSV project which has some sophisticated packages to parse and transform csv data with nodejs streams.

npm install csv

We will further use node as ESM (ECMAScript modules) to be shiningly modern and so lets create a file: index.mjs
Note the .mjs extension, which will tell node to interprete this as ESM. (Since nodejs v12.20.0 && v14.13.0)

We import the packages and create the filesystem streams to read the file, then built a pipeline with the streams and the single steps to process the data and write the results into a new file.
Ok let’s go:
