Pull Request for Issue # .

Summary of Changes

This pull request (PR) fixes the currently broken update path from previous 5.0 alpha versions to the upcoming alpha 4 by fixing points mentioned in the description of PR #41393 :

• Add file '/plugins/schemaorg/blogposting/src/Extension/Blogposting.php' from PR #41260 to the list of files to be renamed on update in file "administrator/components/com_admin/script.php".
• Add uninstallation of obsolete system plugin due to PR #41276 and migration of the obsolete plugin's enabled status and parameters to the new behaviour plugin's parameters on update to file "administrator/components/com_admin/script.php", and add file '/media/plg_system_compat/es5.asset.json' to the deleted files list in in file "administrator/components/com_admin/script.php" because that file is not removed when the plugin is uninstalled due to an incomplete manifest xml of that plugin.

In addition, this PR adds the necessary exceptions to the "build/deleted_file_check.php" script so that the files of the obsolete system plugin which will be removed by the installer when uninstalling the plugin are not added to the lists of deleted files and folders generated by the script.

Finally, this PR here includes also the changes from PR #41393 for easier testing.

As described in that PR, the 2 mentioned points result from deliberate decisions of the release managers, so this PR here is just an offer in case if they decide to change their mind.

Test 2 for the changes in "build/deleted_file_check.php"

1. On a clean, current 5.0-dev branch (no need for having run composer or npm and no need for a Joomla installation), download the following 2 full installation zip packages and save them in the "tmp" folder:

• 5.0.0-alpha3 https://github.com/joomla/joomla-cms/releases/download/5.0.0-alpha3/Joomla_5.0.0-alpha3-Alpha-Full_Package.zip
• Latest 5.0 nightly build https://developer.joomla.org/nightlies/Joomla_5.0.0-alpha4-dev-Development-Full_Package.zip

2. Unpack the 2 previously downloaded zip packages into 2 separate folders in the "tmp" folder, e.g. folders "Joomla_5.0.0-alpha3-Alpha-Full_Package" and "Joomla_5.0.0-alpha4-dev-Development-Update_Package".
3. In a command windows in the directory with your git clone and the branch from step 1, run the following command to check the two folders from the previous step for deleted files and folders (on Windows you have to use backslashes \ instead of slashes / for the paths):

php ./build/deleted_file_check.php --from=./tmp/Joomla_5.0.0-alpha3-Alpha-Full_Package --to=./tmp/Joomla_5.0.0-alpha4-dev-Development-Update_Package

4. Check the 2 created text files ./build/deleted_files.txt and ./build/deleted_folders.txt.
   Result: See section "Actual result BEFORE applying this Pull Request" below.
5. Save the 2 text files from step 4 for later comparison.
6. Apply the changes from this PR.
7. Repeat steps 3 and 4 and compare the 2 text files with those saved in step 5.
   Result: See section "Expected result AFTER applying this Pull Request" below.

Actual result BEFORE applying this Pull Request

Test 1 update from 5.0.0-alpha3

The files and folders of the obsolete "System - Backward Compatibility" plugin have not been removed.

The new "Behaviour - Backward Compatibility" plugin is enabled with the default options.

File '/plugins/schemaorg/blogposting/src/Extension/Blogposting.php' has not been renamed to '/plugins/schemaorg/blogposting/src/Extension/BlogPosting.php'. This will cause schema.org for blog posts not working on Windows or Mac hosts after updates from previous 5.0 alpha versions.

All files and folders belonging to the old "System - Backward Compatibility" are in the lists of deleted files and folders.
