Getting Back into Ruby Solo Hackathon, day 6: Dockerhub is down 😭

OK I realised I could have been live-tooting this the whole time instead of spamming groupchats 😂
Solo #Ruby Hackathon: day 7.
Context is I've been working on upgrading Levelfly, an open-source Learning Management System https://github.com/neuronic-games/levelfly/
The codebase dates back to 2011, with #Rails 3.1.
In 2021, I upgraded it, getting as far as Rails 4 and #Ruby 2.4.
That same year, @autonomic colleage @roxxers and I containerised it to move it from Heroku to a Docker Swarm deployment (using @coopcloud ).
Since then, Levelfly has just had a couple of critical infrastructure fixes… meanwhile Rails 4 hasn't had security updates since 2017¹, and Ruby 2.4 hasn't had any since 2020².

This has involved learning/relearning a LOT of things 😅 Luckily that was the name of the game.
Most satisfying thing so far has probably been finally understanding RSpec enough to be useful – specifically getting my head further around the difference between fixtures, seeds, and factories.
(And then completely ripping out the fixtures lol)
Getting basic #RSpec coverage for the key endpoints going as soon as I'd upgraded to Rails 5 was a great move; those tests have already caught all kinds of issues with the new versions.
Part of me regrets not finding a way to test S3 sooner, because file uploads have always been a big source of bugs in Levelfly, and I built up a small version-hell nightmare for myself by not checking any of that until deep into #Rails 6.
But maybe this was an OK plan: by the time I got to it, I had a lot of practice with dealing with gem dependency issues, writing #RSpec, and writing tests that require other services – all of which turned out to be crucial to getting it going.
(For the curious, I ended up switching to the `kt-paperclip` fork, and using adobe/S3Mock in testing)
Brief aside, I tried to use the fake-s3 Rubygem but the original is deprecated and the last-active fork a) seems abandoned too and b) won't launch without a licence key, is this even allowed in Rubygems.org?! https://supso.org/projects/fake-s3/register
Current status: I borked tests by removing Pusher config from the test environment, thought that was handled automatically by pusher-fake, it is not, need to RTFM.

#Ruby dependency hell …. well, at least purgatory … once again – acts-as-taggable-on needs an upgrade to be compatible with activerecord > 6.2, but that seems to want a zeitwerk upgrade, and THAT seems to want Ruby 3.2. Good thing I got rbenv working! 😅
#Ruby 3.2 kinda works… but seemingly several gems in the bundle use the deprecated File.exists? method (hot take but was this alias really worth removing?).
Monkeypatching third-party gem to the rescue! https://idogawa.dev/p/2023/01/file-exists-ruby.html
While I wait for `bundle update rails` – probably the most dicey step was a #Rails upgrade that required completely deleting `Gemfile.lock`.
File under "very confused that this worked".
Now a real head-scratcher: "DEPRECATION WARNING: Passing instance variables to `render` is deprecated."
Not as many hits on th'internet as for other deprecation warnings I've run into.
I did find a blog post about it¹ but now I'm curious why I didn't see more warnings? (Could just be limited test coverage lol 🙈)

Trying to rush through #Rails 7.1 upgrade before I have to go AFK for the day 🏃🌬️.
Rabbithole mental state update: I've started anthropomorphising the #Ruby gems (and feeling bad torturing them in probably very-unexpected version combinations!)
Back in the saddle!
#Rails 7.1 seems to be working fine – I had to upgrade rspec-rails, which seemingly changed the behaviour of the "as" parameter… but, plot twist, I didn't need to have ever added that in the first place! 😳
Solved this one in 13 minutes on the subway home, actually kinda great conditions for it surprisingly?
A non-screen break and a walk to let my subconscious mull the problem for a bit.
Then, a short time limit and unreliable internet meant I had to skip the usual steps of "searching the error message" and "reading the online documentation" and go straight to the source code – which by now is mostly making sense.
Ran `git reset --hard HEAD^` with uncommited unstaged changes 😭 (luckily not too many, and the key ones were in my vim history)
Making a mental note to add a wrapper script to git to make it bail in these conditions – I would never intentionally drop everything with `--hard`, I would use `checkout`.
Oh no, this is pretty late in the game to be finally paying attention to `new_framework_defaults` 😳
Wow and not only that, I'm not sure I remembered to run `rails app:update` after every Rails upgrade 🫠
Luckily merging the configs is going "OK" so far. Grr so frustrated to be learning yet more things 😾 (not really)
OK the universe didn't punish me too harshly for these mistakes 😇 #Rails 7.1 has the most configuration changes yet! And also some database migrations, exciting!
Wow so far only TWO config options which needed non-default values, all the way from #Rails 4.2, 5.0, 5.1, 5.2, 6.0, 6.1, 7.0, and 7.1 😲
Having the funniest issue where browser tests only run if I switch to a specific GNOME workspace, then away from it, then back to it again? Otherwise I get an HTTP timeout 🤡
If your application has a `--color` flag, be like #Rspec, also support `--colour` as an alias, absolute praxis imo
