[6.0] Updater: Remove Adapter classes from inheritance

[Hackwar]

Summary of Changes

This is an effort to remove deprecated code from the system. The Updater class depends on the Adapter class, which in turn has been deprecated for a long time already. This PR removes the code of the Adapter class from the Updater class and replaces it with some sane methods to add adapters when required.

This PR does some cleanup and it adds the following methods:

• loadAdapters(): This iterates over the set folder and adds all files it finds as available updater adapters. To keep it light, the array only contains the name as key and either the class name as value or an object. The object is instantiated just in time when needed.
• getAdapters(): This method keeps the behavior of the $custom parameter, but otherwise still just returns the list of available adapters
• getAdapter(): This new method replaces loadAdapter() and either returns an object which was previously made or instantiates it from the class stored in the $adapters array.
• setAdapter(): This new method allows to hand in a name for the adapter and either a class name or an instantiated object for the respective adapter type. This would allow you to add custom adapter types and also to overwrite existing adapter types.

I reused some method names from the Adapter class. This PR is a b/c break and thus targeted towards 6.0. This is the corresponding PR to #43792 for the Updater classes.

Testing Instructions

Install an old version of an extension and then run an update for it, both via the normal extension updater and by installing a newer package over the old one. This should work the same both before and after applying the change.

@Hackwar, sorry Hannes more conflicts need fixing. If we can sort this and #43792, we can merge #43794.

[Bodge-IT]

@Hackwar Is this still relevant?

[Hackwar]

Yes, this is still a necessary PR.

[Bodge-IT]

...Awaiting capability to run updater

Thank you for testing. As far as I can see, none of the warnings you got are related to this PR, right?

[muhme]

It seems so, as the deprecations are from different files, as touched with this PR. I was uncertain how to check. I checked now again with the three file names they are touched by the PR and result is zero ✅ 👍 😄

[Hackwar]

Unfortunately I had to do one more cleanup by removing a duplicate call to getAdapter().

Null problemo, let me know when you're done, then I'll test again – my module is now Joomla 6 ready, this was my main effort; maybe put it on DRAFT by then?

[Hackwar]

It is ready. You can test this now.

I have tested this item ✅ successfully on b0685d4

I have successfully tested this.

Used JoomDonation v5.10.9 to update to JoomDonation v5.11.0, also upgraded 2 different Language Packs to latest version.
(I also tried installing a few J6 compatible apps as a test, like Regular Labs Cache Cleaner 9.60 and others)

(the Joomla Updater did NOT find the updated version of JoomDonation online, but I was able to install v5.11 on top of v5.10.9 via uploading the file)

I did NOT test over CLI or locally. I only tested via online my hosting testing environments.

@ exlemor Thank you for testing 👍

the Joomla Updater did NOT find the updated version of JoomDonation online

If you check the update XML https://joomdonation.com/updates/jdonation.xml, there is no 6.0 target platform, so no update is offered correctly.

Thanks for testing, RTC

Thanks everyone, @Hackwar, @muhme & @exlemor . Great work.

[Hackwar]

I can't begin to express how happy I am that this is finally done. Thank you to all who tested, reviewed and now merged. I've been trying to fix the adapter classes during the development of 1.6 and tried again in 2.5 and 3.5. For 4.0 unfortunately I didn't get around to fixing this, but now for 6.0 we can finally get rid of this.
