A really really simple change! It works on the item page, the item
index page, item search, the homepage, and the item lists page.
The main reason I avoided this for so long (even before modernizing the
Rails app) was that the ElasticSearch stuff felt like it made it messy?
But now it's pretty simple, and it works in search already cuz I did
that when I implemented item search, so, nice!
This came in a few parts!
1. Add meta tags to let us know we're logged in.
2. Install React Query, which has the data-loading sensibilities I like
about Apollo without the GraphQL that has honestly been a drag.
3. Replace the outfit-loading and outfit-saving calls with API calls to
the main app.
4. Update the main app's API calls to use our more flexible data
constructs like "pose".
Would've loved to do this more incrementally, but it's hard to! You
can't split out outfit-loading and outfit-saving, or auth from any of
that, or the state gets all out-of-sorts.
Still, this is a good nugget we've pulled out all-in-all, and one that
people have been asking for! Can maybe look to logged-in item search
soon too, for own/want data?
I used the new profiler tools on this page, and noticed a lot of
allocations in the Globalize library, which we use for translating
database records. I realized that we were loading all of the fields of
not just all of the items on the page, but all of their translation
records in all locales! We used to scrape data for lots of languages, so
that can be quite a lot!
Unfortunately, Rails's `includes` method to efficiently preload related
records always loads all fields, and simply can't be overridden.
So, in this change we write manual preloading code, to identify the
records we need, load them in big bulk queries, and assign them back to
the appropriate associations. Basically just what `includes` does, but
written out a bit more, to give us the chance to specify SELECT and
WHERE clauses!
We used to do this for weird clever caching tricks that I don't think
were actually very effective. We stopped using this a few months ago,
and now I'm finally cleaning up this supporting code!
Huh, Arel can *sometimes* handle just having an attribute stand in as
"X is true" in a condition, but sometimes gets upset about it. I guess
this changed in Rails since we recently wrote this?
Specifically, item search would crash on "is:nc" (but *not* "is:np"),
saying:
```
undefined method `fetch_attribute' for #<struct Arel::Attributes::Attribute relation=#<Arel::Table:0x0000000109a67110 @name="items", @klass=Item(…), @type_caster=#<ActiveRecord::TypeCaster::Map:0x0000000109a66e90 @klass=Item(…)>, @table_alias=nil>, name="is_manually_nc">
```
The traceback was a bit misleading (it happened at the part where we
merge all the scopes together), but that hinted to me that it working
with an attribute in a place where it expected a conditional. So I
converted the attribute in the `is_nc` scope to a conditional, and made
the matching change in `is_np`, and that fixed it! Ok phew!
The URL anchors were getting like. double-encoded? The `closet[]` part
was encoding as `closet%255B%255D`. Maybe a thing in Rails, where you
need to mark them `html_safe` to insert them in a URL like that?
Well anyway, those URLs are redundant now, I just have it link straight
to the same outfit page as the big link!
Idk if this used to be different or what, but it looks like the current
behavior is: if you delete a closet list, it'll leave the hangers
present, but Classic DTI would not show them anywhere; but Impress 2020
(until recently) would crash about it.
Now, we use `dependent: :destroy` to delete the hangers when you delete
the list (which I think makes sense, and is different than what I
decided in the past but that's ok, and is what the current behavior
*looks* like to people!), and we add a migration that deletes orphaned
hangers.
The migration also outputs the deleted hangers as JSON, for us to hold
onto in case we made a mistake! I'm also backing up the database in
advance of running this migration, just in case we gotta roll back HARD!
Okay, this is a process that idk if it's even been working for a while anyway, I don't think Neopets translates item names anymore?
And it's crashing when I try to model stuff now, so like. yeah ok I'm fine with just skipping this, it's a shame to lose out on potential data going forward but *I think there just isn't data to get anyway*
I think we used this for both conversion to image, and also for CORS stuff when rendering Flash-based previews… let's trash it, I don't want to be growing our hard drive with files I don't think we use anymore!
If I'm wrong and it turns out we do use them for something, then like. hey I'm sure we'll find out soon enough, and it's very recoverable operation.
Just find_all_by's that I never cleaned up
Oddly enough, I still got a "neopets seems down" message out of this, idk if that's an actual bug or just sluggishness rn
Okay, right, if we're just using www.neopets.com (like we are for now), it fails on http://www.neopets.com because it triggers a redirect that we don't follow.
So here I 1) change the default to HTTPS, and 2) add HTTPS support to our little RocketAMF lib
Nice, just turning it on seemed to do all we need for now!
Fair questions to be asked about like, should you be able to look up by username instead of email? But like idk, this feels simpler *and* more solid, to give you feedback on if it's the right email.
Hey nice!!
Note that I removed an account delete button from the settings page. You can still send a DELETE request to the right endpoint to do it, but it's not gonna delete all the associated records, and I wanna think a bit about how to handle that better before exposing that button.
I noticed this was stopping changing your default list visibility bc contact neopets connection can't be empty, so I fixed that!
And then I just decided to scroll through every `belongs_to` relationship and add optional to the ones that jumped out at me lol
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.
This removes login/logout/session logic for integrating with OpenNeo ID, replacing them with stubs that just redirect to `/?TODO` when you click login, and helpers that act as if you're not logged in.
This gives us a clean slate to plug in new Devise logic to integrate with the `openneo_id` database directly!
No user-facing functionality here yet, just configuring the database connection to work with openneo_id records.
This is a first step in integrating Devise stuff into this app instead of connecting with a weird second app.
My basic testing for this was to temporarily connect to production `openneo_id`, and see `AuthUser.first` correctly return a user!
I had added this many Rails versions ago during the recent upgrade process, because it was in latest Rails but not in the version of Rails I was using when replacing Elasticsearch with MySQL queries. We can remove it now!
lmao I keep forgetting things! note that the negative case of this filter, like the negative case of `fits`, is currently broken because Rails changed the default SQL mode and I didn't notice! We'll need to add a `database.yml` file and set `sql_mode: TRADITIONAL`.
I ran `rails zeitwerk:check`, which eager-loads the app, and it found two problems: `closet_group.rb` doesn't define `ClosetGroup` (cuz it's empty), and I left in a reference to a cache sweeper observer oops. Goodbye!
Rails 5 added new validation on `belongs_to` to ensure the corresponding record exists. In the case of moving to the null list, this shouldn't trigger!
I wish we could flag that specifically `nil` is okay, but other values should be validated? But oh well, this is fine!
Ok so weird little situation, usually Arel will accept an attribute as a param to `order()`, but not when it's in a very specific situation of all of the following:
`Item.joins(:translations).includes(:translations).limit(30).order(Item::Translation.arel_table[:name])`
For some reason, it's all like "hey I can't call `to_sql` on an attribute!", but only in the scenario where all 3 of those other things are present. Weird!
Anyway, explicitly saying `.asc` fixes this. Ok!
Some important little upgrades but mostly straightforward!
Note that there's still a known issue where item searches crash, I was hoping that this was a bug in Rails 4.2 that would be fixed on upgading to 5, but nope, oh well!
Also uhh I just got a bit silly and didn't actually mean to go all the way to 5.2 in one go, I had meant to start at 5.0… but tbh the 5.1 and 5.2 changes seem small, and this seems to be working, so. Yeah ok let's roll!
Some tricks required here to get the dependencies to work out, but we got it!!
Oh also, we move away from the rbenv in Ubuntu's package manager, because it doesn't support more recent Rubies like 2.4.10.
This labeling technique hasn't worked in a long time bc it requires being logged in. These days we just manually label them with the 2020 support tools I think!
Clearing out the Neopets gem should help us manage some gem dep conflicts in the 4.2 upgrade too (I think the nokogiri one gets tricky?)
At one point we piloted a "Camo" service to proxy HTTPS image urls for us, but it doesn't exist anymore.
We already have proxies and stuff for this, so I left `Image` as a placeholder for this, but it's not working yet!
This also deletes our final reference to the Addressable gem, so we can remove it!
I don't think these work anymore, and our volunteers get new items into the db fast anyway, Impress 2020 is doing better spidering these days. And then we get to remove the cron job `whenever` gem!
Using `s3_path` and stuff made it sound like we were still referencing the original Amazon S3 images - but actually our new asset proxy just uses the same path structure, and we didn't change anything about it.
Oh also I deleted an after_conversion method that isn't used anymore, forgot about that!
We've already swapped out the backend for this stuff to Impress 2020, so the resque task and the broken image report UI aren't actually relevant anymore. Delete them!
This helps us delete Resque soon too.
Idk this one might actually be a bit of a pain to load? But I'd want to optimize it differently anyway, and there's overhauls we're already planning to do here.
Huh! This cache key seemed to only be referenced in checks and expirations, but was never actually used! So I guess we've been loading the modeling predictions every time for a while huh??
We'll get smarter about that someday, but anyway, that lets us delete our Item resque tasks and ItemObserver!
Again I'm just not convinced of the perf on this, and it enables us to delete some whole infra over it, we can improve it another time if it's useful to!
Just removing some caching and the expiration of it! There's still more superfluous(?) caching on the item page to audit, but these seem a bit more sensible about avoiding loading extra data.
In the interest of clearing out Resque, I'm just gonna remove a lot of our more complex caching stuff, and we can do a perf pass for things like big item list pages once everything's upgraded. (I'm hopeful that the upgrades themselves improve perf; and if not, that some improved sensibilities 10 years later can find simpler approaches.)
We uninstalled Flex, our Elasticsearch gem, to replace item search with direct DB queries; but I forgot these calls, oops!
I also kinda want to see about deleting the resque tasks altogether, since I'm not sure how to get Resque installed on latest rails bc there seems to be a conflict over the version of Rack? And it'd be nice to get rid of the complexity if we can.
Back in the day, `all` would immediately load up a query into an array, but now I think it's an alias for what `scoped` used to be: a relation that contains everything.
Not being a subquery is better! I realized later that a LEFT JOIN would probably do it even betterer? with like `HAVING count(x) = 0`? but the `left_outer_joins` method doesn't seem to be in Rails 4, and I don't want to do stringy joins, so this is fine for now!
Right, previously we were querying "has *at least one asset* that is not in zone X" instead of "has NO assets that are in zone X".
I don't know a fast way to query for that, this will have to do for now!
Not doing the tricks with `is_positive` anymore, instead just calling different functions altogether at the call site.
Also, instead of classes, I feel like this is a lot more concise to just write as class methods that create certain instances of a trivial `Filter` data class. Without the tricks of `is_positive` in play, the value of classes goes way down imo.
Ohh ok, without this change all of our `scope`s were just immediately evaluating the argument and fetching _all_ such matching records immediately, instead of waiting to actually be called. This led to bugs like `pet_type.as_json` returning ALL pet states in the whole db, because the `PetState.emotion_order` scope was being treated as a single predefined query, rather than a query fragment to merge into the current context.
This also explains what happened in 724ed83: that's why things before the scope in the query were being ignored.
Idk why, but when the `select` was the first thing in the query, it was getting ignored. I wonder if there's something about the `object_assets` scope that I'm not understanding that's overwriting it? Or the `joins`? But whatever, this works, I'm not worried about it for now!
We'll need to replace the item search query stuff with direct MySQL queries, but that's not ready yet bc the app still isn't booting, so we're committing this in a known broken state for now!
We set up `impress-asset-images.openneo.net` to redirect to the right asset, without needing to depend on AWS anymore for HTML5-converted items!
Our quick fix for this: always serve `has_image: true` to the frontend, so it always tries to use the image, regardless of whether we've marked it as converted in the database. (We've turned off the converters too!)
Oh, yeah, shit, okay, when we set `self.url` like that, it's supposed to be the _canonical_ URL for the SWF, not our proxied one—this is the URL that's gonna go in the database.
We do proxying late in the process, like when we're actually setting up to download something, but for just referencing where the asset lives, we use `images.neopets.com`.
In this change, we revert the use of `NEOPETS_IMAGES_URL_ORIGIN`, but we _do_ update this to `https` for good measure. (We currently have both HTTP and HTTPS urls in the database, I guess neopets.com started serving different URLs at some point, this is probably the future! And anything interpreting these URLs will need to handle both cases anyway, unless we do some kind of migration update situation thing.)
We're migrating the incorrect assets with the following query (with the limit changed to match the number we currently see in the DB, just as a safety check):
```
UPDATE swf_assets SET url = REPLACE(url, 'http://images.neopets-asset-proxy.openneo.net', 'https://images.neopets.com') WHERE url LIKE 'http://images.neopets-asset-proxy.openneo.net%' ORDER BY id LIMIT 2000;
```
Okay, like in the previous commit, we're dealing with forced HTTPS, on a server that isn't going to cooperate with our dependencies' HTTPS version. And this time, I don't think there's a secret origin server that will accept `http://` requests for us.
Thankfully, we have the perfect hack in our back pocket: our own pre-existing images.neopets.com proxy server! I set the following in our secret `.env` file, and now we're good:
```
NEOPETS_IMAGES_URL_ORIGIN=http://images.neopets-asset-proxy.openneo.net
```
Oops, neopets.com finally stopped accepting `http://` connections, so our AMFPHP requests stopped working! And our current dependencies make it hard to make modern HTTPS requests :(
Instead, we're doing this quick-fix: we have a connection who knows the internal address for the Neopets origin server behind their CDN, which *does* still accept `http://` requests!
So, when `NEOPETS_URL_ORIGIN` is specified in the secret `.env` file (not committed to the repository), we'll use it instead of `http://www.neopets.com`. However, we still have that in the code as a fallback, just to be a bit less surprising to some theoretical future dev so they can see the real error message, and to self-document a bit of what that value is semantically doing! (The documentation angle is more of why it's there, rather than an actual expectation that any actual person in the future will run the code and get the fallback.)
There's a bug on Neopets.com that breaks links and images for *.openneo.net, on petpages specifically.
So, we've registered a new domain, and we're using that to serve outfit images now.
I'm a bit hesitant to add a new domain name to our like, permanent URL surface area, lol… but I'm not hearing back from TNT, and I already closed the doors on S3, so… here we are, whatever 😅
TNT started using HTTPS URLs! And our old Ruby version (lol 😬) still requires explicit invocation to perform SSL during a request, so requests were failing!
Now, we explicitly build the `Net::HTTPS` object, and turn on `use_ssl` if it's an HTTPS URL! (The shorthand invocation didn't seem to have an option for this, that I could find!)
Here, we turn off the hooks that enqueue outfit image updates, and we disconnect the `OutfitImageUploader` that manages uploaded S3 URLs, instead replacing it with an `image` method that simulates the same basic API.
This should cause _all_ views on Classic DTI to use the new outfit URLs. Some notable examples:
- The user's Outfits page
- The donations page
- The outfit page, and its sharing metadata
I hope I didn't miss anything in the views that will make this crash stuff! I tested the new model code in the Rails console, and checked it against invocations that I noticed when searching the codebase for `outfit.image` 🤞
Oops, right, I meant to use the new `impress-outfit-images.openneo.net` host for this! It works just fine from `impress-2020.openneo.net` as the backing source right now, but I want these semi-permanent URLs to be a bit more decoupled.
As part of our project to get off S3 and dramatically reduce costs, we're gonna start serving outfit images that Impress 2020 generates, fronted by Vercel's CDN cache! This should hopefully be just as fast in practice, without requiring an S3 storage cost. (Outfits whose thumbnails are pretty much unused will be evicted from the cache, or never stored in the first place—and regenerated back into the cache on-demand if needed.)
One important note is that the image at the URL will no longer be guaranteed to auto-update to reflect the changes to the outfit, because we're including `updated_at` in the URL for caching. (It also isn't guaranteed to _not_ auto-update, though 😅) Our hope is that people aren't using it for that use case so much! If so, though, we have some ways we could build live URLs without putting too much pressure on image generation, e.g. redirects 🤔
This change does _not_ disable actual outfit generation, because I want to keep that running until we see these new URLs succeed for folks. Gonna wait a bit and see if we get bug reports on them! Then, if all goes well, we'll stop enqueueing outfit image jobs altogether, and maybe wind down some of the infrastructure accordingly.
Oops, if you saved `SwfAsset` outside of modeling code, the `item` field would be empty, and so `item.body_specific?` wouldn't happen.
This would trigger when you even just report a broken image!
Now, we always run the SQL query to check for that flag.
