Ah right, now that you no longer need to provide this secret value as a
query param or a cookie in order to see NeoPass stuff, we can safely
delete it! Goodbye! 👋
Hacky and inconvenient, but it works!
I want this primarily to enable me to live-debug what info we're
getting back in the auth token. In production right now, the flow with
NeoPass succeeds, but we fail to create the account, and my production
error logs say it's because the username field is too long. I had hoped
it would just be the Neopets username, but now that I've poked at
NeoPass itself a bit, I'm realizing it won't be that simple.
So, we'll use this to investigate!
Wowie, it's starting to happen! :3
When you run this in production, though, you get back the auth failure
message, and the OmniAuth logs say the server returned the following:
> invalid_client: Client authentication failed (e.g., unknown client,
> no client authentication included, or unsupported authentication
> method). The OAuth 2.0 Client supports client authentication method
> 'client_secret_post', but method 'client_secret_basic' was requested.
> You must configure the OAuth 2.0 client's
> 'token_endpoint_auth_method' value to accept 'client_secret_basic'.
I'll add a fix for this in the next commit, with some explanations as
to why!
Ah right, I went and checked the Devise source code, and the default
implementation for `password_required?` is a bit trickier than I
expected:
```ruby
def password_required?
!persisted? || !password.nil? || !password_confirmation.nil?
end
```
Looks like `super` does a good enough job here, though! (I'm actually
kinda surprised, I wasn't sure how Ruby's `super` rules worked, and
this isn't a subclass thing—or maybe it is, maybe the `devise` method
adds a mixin? Idk! But it does what I expect, so, great!)
So now, we require the password if 1) Devise doesn't see a UI reason
not to, *and* 2) the user isn't using OmniAuth (i.e. NeoPass).
This had caused a bug where it was impossible to use the Settings page
*without* changing your password! (The form says it's okay to leave it
blank, which stopped being true! But now it's fixed!)
Right, I didn't totally connect the dots that there's some OpenID
features in the mix here for how we expect to identify the user once
they authenticate. It requires looking up the provider's public key,
and validating the JWT they sent us. This gem does all that for us!
I don't actually know what a real NeoPass `id_token` looks like yet?
But I'll fill in some placeholder stuff for now, and use that for
initializing the account!
In this change, we wire up a new NeoPass OAuth2 strategy for OmniAuth,
and hook up the "Log in with NeoPass" button to use it!
The authentication currently fails with `invalid_credentials`, and
shows the `owo` response we hardcoded into the NeoPass server's token
response. We need to finally follow up on the little `TODO` written in
there!
If you pass `?neopass=1` (or a secret value in production), you can see
the "Log in with NeoPass" button, which currently takes you to
OmniAuth's "developer" login page, where you can specify a name and
email and be redirected back. (All placeholder UI!)
We're gonna strip the whole developer strategy out pretty fast and
replace it with one that uses our NeoPass test server. This is just me
checking my understanding of the wiring!
I'm starting to port over the functionality that was previously just,
me running `yarn db:export:public-data` in `impress-2020` and
committing it to Git LFS every time.
My immediate motivation is that the `impress-2020` git repository is
getting weirdly large?? Idk how these 40MB files have blown up to a
solid 16GB of Git LFS data (we don't have THAT many!!!), but I guess
there's something about Git LFS's architecture and disk usage that I'm
not understanding.
So, let's move to a simpler system in which we don't bind the public
data to the codebase, but instead just regularly dump it in production
and make it available for download.
This change adds the `rails public_data:commit` task, which when run in
production will make the latest available at
`https://impress.openneo.net/public-data/latest.sql.gz`, and will also
store a running log of previous dumps, viewable at
`https://impress.openneo.net/public-data/`.
Things left to do:
1. Create a `rails public_data:pull` task, to download `latest.sql.gz`
and import it into the local development database.
2. Set up a cron job to dump this out regularly, idk maybe weekly? That
will grow, but not very fast (about 2GB per year), and we can add
logic to rotate out old ones if it starts to grow too far. (If we
wanted to get really intricate, we could do like, daily for the past
week, then weekly for the past 3 months, then monthly for the past
year, idk. There must be tools that do this!)
The Neopets Media Archive is a service that mirrors `images.neopets.com`
over time! Right now we're starting by just loading manifests, and
using them to replace the hacks we used for determining the Alt Style
PNG and SVG URLs; but with time, I want to load *all* customization
media files, to have our own secondary file source that isn't dependent
on Neopets to always be up.
Impress 2020 already caches manifest files, but this strategy is
different in two ways:
1. We're using the filesystem rather than a database column. (That is,
manifest data is kinda duplicated in the system right now!) This is
because I intend to go in a more file-y way long-term anyway, to
load more than just the manifests.
2. Impress 2020 guesses at the manifest URLs by pattern, and reloads
them on a regular basis. Instead, we use the modeling system: when
TNT changes the URL of a manifest by appending a new `?v=` query
string to it, this system will consider it a new URL, and will load
the new copy accordingly.
Fun fact, I actually have been prototyping some of this stuff in a side
project I'd named `impress-media-server`! It's a little Sinatra app
that indeed *does* save all the files needed for customization, and can
generate lightweight lil preview iframes and images pretty easily. I
had initially been planning this as a separate service, but after
thinking over the arch a bit, I think it'll go smoother to just give
the main app all the same access and awareness—and I wrote it all in
Ruby and plain HTML/JS/CSS, so it should be pretty easy to port over
bit-by-bit!
Anyway, only Alt Styles use this for now, but my motivation is to be
able to use more-correct asset URL logic to be able to finally swap
over wardrobe-2020's item search to impress.openneo.net's item search
API endpoint—which will get "Items You Own" searches working again, and
whittle down one of the last big things Impress 2020 can do that the
main app can't. Let's see how it goes!
I've moved the support secret into the encrypted credentials file, and
moved the origin into a top-level custom config value in the
environment files, with different defaults per environment but still
the ability to override it. (I don't use this, but it feels polite to
not actually *demand* that people use port 4000, y'know?)
In impress-2020, we do a big slow query to figure out which users have
been active in trades recently. Now, we cache that timestamp on the
User model.
This won't have any immediate effect; it's to clear the way for Classic
DTI to receive the better trade ratios feature people like from 2020.
I also added some unit testing infra because I finally wanted it! for
all the ways you can trigger this timestamp lol
Note too that this is a bit of an unusually complex migration, but my
hope is that the batching and query structure and such helps it run
surprisingly fast! 🤞
I noticed when running `rails routes` that there's a lot of routes for
major unused Rails features, like storage. I didn't look deeply enough
into ActiveStorage to know if I was risking accepting arbitrary file
uploads, I just figured, if I disable it (which simplifies the app
footprint anyway), then I can be certain! So, goodbye!
The usual stuff! Installed the new gem and its new deps, ran
`bin/rails app:update` and did my best to manually merge the dev/prod
config files with the new canonical defaults, deleted some migrations I
don't think are relevant to us, and yeah!
Also, Rails 7.1 seems to need `libyaml-dev` installed, so I added that
to the `deploy/setup.yml` playbook!
One thing to note is that, while I was here, I turned on some settings
relating to our use of SSL that technically weren't on before. This
should be fine and helpful? But if stuff breaks, well, check those!
I did some refactoring while here too, of pulling the deploy scripts out of `package.json` and into `bin`, to be a bit more canonically Rails-y. (idk how canonical the colon thing is but, probably fine??)
I don't know enough about our caching situation to know where memcache performs meaningfully better than Rails's in-memory cache. Let's delete it for now and see if there's a problem, to simplify the deploy environment!
A lot of rough edges here (e.g. no styles on the flash messages), but it's working and that's good!!
I tested this by temporarily switching to the production database and logging in as matchu!
Still missing a lot of big features too, like registration, password resets, settings page, etc.
Whew! Seems like a pretty clean one? Ran `rails app:upgrade` and stuff, and made some corrections to keyword arguments for `translate` calls. There might be more such problems elsewhere? But that's hard to search for, and we'll have to see.
This one was pretty straightforward yaay! Main thing was the change from `render file` to `render template` in a couple places, oh and a thing with complex `order()` clauses.
During this upgrade process, `rails server` hasn't been updating its logic when files changed, so every change had to be accompanied by a restart.
This turned out to be because Vagrant's networked filesystem to share between the host and guest systems doesn't support the filesystem update events Rails is listening for. So, we switch to a simpler file watcher that does more work but doesn't depend on the filesystem events!
It's unused, and I'm just double-checking that it's not somehow causing the issues with the rails dev server not reloading classes. (The `threadsafe!` option would do that, but I don't thiiiink this is the env we're running? But I'm wondering if the loader is getting confused by the prefixiness of the name or something. Unlikely!)
This is recommended by the Rails 4.0 upgrade guide:
> The caching method changed between Rails 3.x and 4.0. You should change the cache namespace and roll out with a cold cache.
I noticed too that old cache entries with old character encodings were a real problem, so yeah making sure we're working with a cold cache is smart!!
NOTE: This doesn't boot yet! There's something changed in the `devise` API that we'll need to fix!
```
/vagrant/config/initializers/devise.rb:46:in `block in <top (required)>': undefined method `encryptor=' for Devise:Module (NoMethodError)
```
But yeah, we navigated the gem upgrades, and also I ran `rake rails:update` and hand-processed the suggestions it had for our config files.
