I stopped working on the Osm Admin project, for financial reasons. Did it hurt? A lot. Was it necessary? Unfortunately, yes. This post is a short retrospection on this matter.

This time, I tackled adding an explicit property to an existing table, and then making it non-nullable.
It raised the need for data conversions - additional handling of the existing data - or otherwise, the database engine fails, or the data becomes invalid.
And it made me split migrations in two parts - the one that runs before the data conversion, and the other one that runs afterwards.

While working on diff algorithm I noticed a certain pattern that I use over an over again.
Using this pattern, I implemented notification table diff.
Finally, I rearranged diff/migration code for better code readability.

After a system update, I've got some problem with my laptop, and one thing to check was system log files.
This got me thinking: what makes a good log for my own application? And I think that application logs are as useful as they are able to answer potential questions I may have when an application is in production.
Let's think what kind of questions I might have, and what information might be useful to answer them.

Recently, I fixed numerous issues to make the first migration tests work.
Then, I started implementing the schema diff algorithm - the basis for schema migrations.

More dots got connected in the schema migration design, see this post for details.
Then, I tried to return to TDDing it, but strange errors met me there, so I left them to be resolved in the next piece.

Schema migrations are going to be generated and executed automatically under gulp watch
. It will result in lots of tiny migrations: add a column, change its type, make it not nullable, and so on.
It's convenient during development, but it might be not optimal to reapply in production. Indeed, it's better to convert a large table to new structure all at once rather than running a conversion for each of the tiny migration.
This observation contradicts the previously stated migration workflow, so let's update it.

In spirit of TDD, I started with a meaningful, but failing test that is reasonably fast. Then, I worked to make it green:

The goal of the current iteration is to adjust the database schema and preserve/convert existing data according to any changes in schema classes, grids, forms or indexers.
This post presents some thoughts how it might work with class definitions.

Now, saving a product complains:

For other control types, a step-by-step guide is prepared.

In Osm Admin, object editing form is used not only for a single object editing, but also for editing multiple objects, and for creating a new object.
I also created the osmphp/extras
package as an easy way of adding Font Awesome icons to a project. Later, I'll add more optional reusable goodies to this package.

I redesigned control rendering on list and edit pages. From now, a control contains view prototypes for a grid column, a form field, and other.

A View
is a short-living object that is created and computed during page rendering. You can also create a pre-configured a View
object prototype in advance, and then clone it for rendering.
It's important not to execute render-time properties while configuring the prototype.
Use view()
helper function to create render-time view instances, and mark render-time properties using #[RenderTime]
attribute to prevent accessing them before rendering.

Yesterday, I optimized search responses, made search hit limit explicit, and decided not to obfuscate ID in URL.

The implementation of the faceted implementation in osm.software
blog has shown that sometimes you need only facet counts, or only total count of matching entries.
Until now, Osm Framework had always queried total count
, ids
and facets
. Not anymore - and the search engine only provides the information that is actually needed.

The implicit ElasticSearch hit limit is confusing. And you can't get all the hits - there is 10000 maximum hit limit that you can't exceed anyway.
Be explicit about the maximum number of search hits.

This sprint was dedicated to writing Osm Framework documentation, and indeed, there are 8 new in-depth documentation articles, 4-5 minutes long each.
Despite documentation focus, I kept improving the website. From now on, you can assign a canonical URL to a blog post or a documentation page, and use GitHub friendly relative URLs in documentation.
But the most important thing - I started sharing progress and insights daily on Twitter.

In Osm Framework, an application is a set of modules that you run as a whole. There are several applications defined in the project, each having its own PHP class. Mostly, deal with the main one, Osm\App\App
. Beside the class name, every application also has a name, the main one is named Osm_App
.
Access the current application object, and the main parts of Osm Framework, via the global $osm_app
object and its properties. Add your own long-living objects there. Run an application using its HTTP or console entry point, or using Apps::run()
.

Modular software development is a well-known practice of dividing your application into several modules, each doing one thing, and doing it well. It increases readability and simplifies maintenance, as application concerns are fully separated from one another, easier to reason about, and to debug.
Modular development also encourages reuse. It's like a puzzle. Using one set of modules, you'll get an e-commerce application, using another set of modules - you'll get a blog application.

Computed properties are one of Osm Framework pillars. They help to execute code only once, and only if it's actually needed. Computed properties control object serialization and caching. They provide meaningful insights into class interdependencies. Finally, computed properties are easy to test.

After pushing changes to GitHub, osm.software website is updated without any additional manual action. On push, GitHub executes the deployment script on the production server. Most changes are done to content only, and in this case, the deployment script only updates the search index. Otherwise, with the website being on maintenance, it additionally updates Composer and Node dependencies, builds JS and CSS assets, and runs the database migrations.
