XLP DevOps Process

Step 1

Upgrade current container to Mediawiki 1.35 to latest stable version [1.37.1]

First attempt, is to update the container image to use available docker image in Mediawiki container in Docker Hub, version 1.37.1; and adjust/upgrade all the related extensions to the version that support Mediawiki 1.37.1. The major extension that is need to be adjusted is Semantic MediaWiki, and MediaWiki Language Extension Bundle (MLEB). The motivation to upgrade to Mediawiki 1.37.1 is to enable the Content Translation Feature, to enable translation process using automatic translation function, the goals can be see in Content Translation Demo page.

Platform compatibility and release status

SMW	PHP	Media Wiki	Released	Status
4.1.X	7.4.0 - 7.4.x	1.35.0 - 1.37.x	-	Development
4.0.X	7.3.0 - 7.4.x	1.35.0 - 1.37.x	2021-01-18	Stable release
3.2.x	7.1.0 - 7.4.x	1.31.0 - 1.35.x	2020-09-07	Obsolete

Based on table above, SMW Version 4.0.X and MediaWiki 1.37.X, runs on PHP 7.4.X is the version combination that we are going to use, and written into DockerFile configuration. To minimized the complexity, decided to remove all other extensions to ensure both SMW and MLEB is running correctly, thus we can localized if we found any of the extensions is having trouble.

Adjustment made on composer.local.json, as shown below

{
    "require": {
        "rht/merkle-tree": "dev-master",
        "mediawiki/maps": "9.0",
        "mediawiki/semantic-media-wiki":"~4.0",
        "mediawiki/semantic-result-formats": "~3.2",
        "mediawiki/semantic-cite": "~2.1",
        "mediawiki/sub-page-list": "~1.4",
        "mediawiki/semantic-scribunto": "~2.2"
    },
    "extra": { 
	 	"merge-plugin": { 
			"include": [ 
				"extensions/OpenIDConnect/composer.json" 
			] 
		}
	}
}

As the docker build process is runned, it shows incompatibility error between Semantic Media Wiki 4.0, Semantic Result Format 3.2, and Semantic Cite 2.1; To make the process running, decided to remove both of extension and the build process is running well. The proceed to add MLEB extension into the container.

Docker container build error

First attempt on installing the MLEB is through the git, using below command, and copy the result into the container. Not by running the code inside the docker build.

for ext in Babel cldr CleanChanges LocalisationUpdate Translate UniversalLanguageSelector
do
  if [ ! -d "$ext" ]
  then
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/$ext.git
  fi
  cd $ext; git fetch --tags; git checkout 2022.01; cd ..
done

Then, the container is pulled to test server, and proceed with Semantic Media Wiki, Translation functionality. The test result is failed on the Preparation Step. It supposed to show top link of "Mark this page for translation", while other functionality accessed in Special Pages is shown and accessible.
To further investigate the error, debug feature is turned on and inspected. Inspection from SQL debug and debug log did not shown any error, however one of the query to revpage table did not show any result. It seems that the record that is supposed to be inserted into revpage table is failed, which causing the translation marking link cant be shown on top of the page. In attempt to fix the error, also tried to change the extension source-code from official released, instead of git hub source code found in this link. After replacing the extension source code and rebuild the container image, the Mediawiki shows similar result.
