Maintaina/Horde UTF-8 on PHP 8
On recent OS distributions, two conflicting changes can bring trouble. MariaDB refuses connections with ‘utf-8’ encoding Recent MariaDB does not like the $conf[‘sql’][‘charset’] default value of ‘utf-8’. It runs fine if you change to the more precise ‘utf8mb4’ encoding. This is what recent MySQL understands to be ‘utf-8’. You could also use ‘utf8mb3’ but this…

Simplifying Routing / PSR-15 bootstrap in Horde
As you might remember from a previous post, Horde Core’s design is more complex than necessary or desirable for two main reasons: Horde predates today’s standards like the Composer Autoloader and tries to solve problems on its own. Changing that will impair Horde’s ability to run without composer which we were hesitant to do, focusing…

PHP 8 Horde (Maintaina)
Over the next few days, all Horde libraries and apps in the maintaina-com organization will be whitelisted for PHP 8x. in their FRAMEWORK_6_0 branch development versions. One next step will be a flavour of the OpenSUSE based containers and deployments which runs off PHP 8.0. While some few libraries have been enabled for PHP 8,…

Horde/Skeleton: Modernized
Over the last months, a lot of new technologies have entered the Horde ecosystem. It was long overdue to modernize the Skeleton example app. No more un-namespaced code Skeleton has completely migrated to PSR-4 namespaced code in /src/ rather than traditional, unnamespaced code in /lib/. This includes framework integration classes like Application, Api, Ajax\Application but…

Horde/Log Rewrite goes PSR-3
I have rewritten Horde/Log based on the PSR-3 Logging standard published by PHP-FIG. Why? It had to been done at some point. The current wave of Corona pandemic has cancelled some joyful other activities planned for this weekend and I had been looking into PSR-3 loggers for quite some time. Most importantly, I wanted to…

Custom iCalendar data in Kronolith & Nag
The iCalendar exchange format is everywhere in Horde’s calendar (kronolith) and tasks (nag) apps. It is offered for manual import/export. It is the centerpiece of the CalDAV synchronisation protocol and various APIs of these apps. The format also plays a role in email invitiations and updates sent via iTip. It is a very powerful and…

Maintaina Horde switches to openSUSE LEAP
Our Horde docker images have switched over from Tumbleweed to openSUSE LEAP once again. Recently our container build CI job in github.com broke down unexpectedly. An investigation showed that Tumbleweed’s core libraries, especially libc, were too new for the CI’s build system, based on Ubuntu LTS. This is the second time we abandoned the Tumbleweed…

Can Horde’s internal API use PSR-7 Messages?
Applications call into abstract services backed by other apps, with limited coupling. This may sound a little like micro services, but predates the concept by a decade. Horde’s registry routes the call to the implementing app if present. For example, both “sam” and “ingo” applications implement some spam filter related API calls. Registry setup decides…

Authentication & Authorization is complex
Could there be any more straight forward topic than authentication & authorization? The user provides user name and password and clicks “login”, the backend checks if credentials are valid. Invalid credentials are not authorized, valid credentials are authorized and identified (authenticated). End of story. Right? Well… in many cases, it’s not that trivial. As a…
