I have been reading the RESTbase installation instructions, which I don't find that clear, so I don't feel comfortable with just trying to follow them on the production wiki. Instead, I will test them on my own computer's mediawiki-1.31.1 (LTS) installation to make sure I can set RESTbase up properly first. MediaWiki has a lot of Easter eggs! I am starting to feel like I'm going down the rabbit hole.

Anton-Latukha commented 5 years ago

Yes quite a broad topic. Ironically MediaWiki engine keeps it's own big Wiki. It is a very broad and deep topic. One rabbit hole at a time.

Thank you @hgolden

Please, if you can, keep relative track of your setup somewhere on GitHub/GitLab or gitlab.haskell.org.

gbaz commented 5 years ago

I think this is resolved?

hgolden commented 5 years ago

@gbaz, no I still need to work on this. I had overlooked it. Sorry! It appears that the Typeclassopedia article displays correctly, but the RESTbase extension may be needed for the visual editor or something else (I still don't have a good understanding of RESTbase and its use). I will work on this starting tomorrow (2019-09-04), implementing it first on my local machine to avoid damaging the production wiki since I need to experiment first.

Anton-Latukha commented 5 years ago

Updated.

Overall - I'd would not hurry with it, lowering priority, but make a good diagnose, and solution probably must be simple.

It indeed happens particularly on Firefox (even in clean safe-mode of a browser). Also I use NixOS - that also is special about setup and can be somehow related, like something searching hardcoded /... path of something.

Anton-Latukha commented 5 years ago

@hgolden If you would direct me roughly what to look for - I would know what to look to profile, and return with results. If you do not know the cause - then I would learn how to do general web-profiling procedure.

hgolden commented 5 years ago

@Anton-Latukha @gbaz I am going to implement RESTBase using the SQLite backend on my own desktop computer first. At the same time I will upgrade to the latest LTS version. I will test everything as well as I can doing this. Only then will I update the production wiki. I would be happy to allow each of you to run your own tests on my machine to get your concurrence before updating the production wiki. I will set up a dynamic DNS to allow your access once it is ready to test. (I have just upgraded my desktop with more RAM, disk and CPU cores so I can do the work locally.)

Anton-Latukha commented 5 years ago

You are serious about this stuff.

I would test how I can.

But as I said, I were a contributor on Arch Wiki pages & learned back then that in depth, and learned MediaWiki and setted-it up locally with some number of plugins. It was years ago.

I can take upon an effort to move your configuration to Ansible, or contained build, or even after that - NixOS, or even try Guix. If talking about the community - I can clean-up my other efforts & devote time to manage NixOS configs for Haskell MediaWiki, I would need to write management of in nixpkgs at first, because there is MediaWiki package, but there is no automatic server deployment options written for it. I think MediaWiki inside is pretty stateful, not including the data, so writing automation for it in NixOS can take effort.

But at the time - I would test.

hgolden commented 3 years ago

I willl include RESTbase in the dockerized upgrade to MediaWiki-1.35.2 I am working on presently.
