A while ago I stared at the slow query log of a customer’s shop. Three seconds for this one: Great. But who sent it? The listing? A plugin? The sitemap generator? Some CMS element? The DAL generates SQL, and generated SQL looks the same everywhere. So the usual detective work begins: copy the query, grep the codebase, guess which filter combination produces exactly this WHERE clause, attach Xdebug, cry a little.

Deliverability („Zustellbarkeit“) ist der Vorgang, mit dem E-Mails in den Posteingängen der Abonnenten landen – und es ist eine Kunst… und eine Wissenschaft. Denn viele Aspekte liegen in unserer Hand (Infrastruktur, E-Mail-Vorlagen…) und auf andere wiederum haben wir keinen direkten Einfluss, etwa die Regeln, welche die E-Mail-Provider zur Entscheidungsfindung („Das ist Spam!“) benutzen. Das heißt […]

I attended the fifth SCUC – my third visit overall. Unlike a regular conference with hundreds or even thousands rushing through crowded halls to attend one-sided presentations, SCUC’s format in which themes are proposed and presented by the participants results in compelling panels, presentations, and open discussions. The mixture of Developers, PMs, ecommerce agencies and […]

We have a template which generates documents for us. Unfortunately it broke with the following error: In short, the plugin tries to find vendor/tecnickcom/tcpdf/examples/barcodes/tcpdf_barcodes_2d_include.php. But it is looking in shared/vendor and not in /vendor. Why is this? Because we use deployer to throw code on the server and the custom/plugins directory is shared between the […]

We run deployer to deployer our Shopware 6 shops in combination with shopware-cli and Shopware’s deployment-helper. But we had one problem, during deployment the old theme breaks, because compiling the theme regenerates the themeSeed on the database and the new theme is generated in another directory than the old theme. We thought about using Shopware’s […]

A couple of weeks ago, PHP Storm started taking too long to perform the most simple tasks – even navigating through the file tree to find a specific location would trigger the Mac’s iconic spinning beach ball. My first suspicion had to to with the file indexing, but changing the setup and disabling file indexing […]

The examples are from Shopware 6.5.6.1. Today I debugged code with my colleague Bruno. We had the problem, that our Subscriber triggers, but at the wrong moment. As Shopware developers, we often implement our subscribers using the eventClass. This method is commonly used „everywhere“ … Well, not entirely… One small village of indomitable Gauls still […]

I had the pleasure to give a workshop today at the Shopware Community Day 25 in Cologne. To not forget it, here are the slides: And here is the repository with the current code: https://bitbucket.org/winkelwagen/deployer-pub/src/sw-workshop/ If you have any questions, feel free to comment and I’ll update the blog post!

If your bitbucket shell runner is doing weird stuff, you might have started the runner two times – in my case under different users (root + winkelwagen) and therefore it didn’t show up when looking for the screen.

I setup a proxy pass to have the app on one server and the hostname terminate by DNS on another machine. Setting up a reverse proxy is pretty easy: But for some reason, Safari doesn’t like the response. The important part is to NOT pass the Upgrade header on to the backend machine – don’t […]

Today I learned, one can use JSON in Magento 1’s layout xml. Tell Magento which action parameter are json and that’s it. You can tell Magento that only one parameter is json, like this. Then Magento decodes the json and uses it. I was very lucky to see it today, because I needed an array. […]

This only works on Magento 2.4+ You want to use Amazon AWS Simple Email Service to send your transaction mails? It took a moment, but maybe you want to safe the struggle, let me tell you, what to configure: Go to Stores > Configuration > Advanced > System > Mail Sending Settings Configuration Value Transport […]
