Yay, we got the API endpoint for this! The `linkage` scope is the key.
Rather than pulling back the specific fallback behavior we had wrote
for usernames before, which was slightly different and involved
appending `neopass` in there too (e.g. `matchu-neopass-1234`), I
figured let's just use a lot of the same logic, and just use the
preferred name as the base name. (I figure the `neopass` suffix isn't
that useful anyway, `matchu-1234` kinda looks better tbh! And it's all
fallback stuff that I expect serious users to replace, anyway.)
Oh right, I never did catch this when setting up User-Agent in the app!
(I noticed this because I'm making a new request now, and went to look
how we set it in previous stuff, and was like. Oh. We don't anywhere
right now. Interesting LOL)
Oh right, if you can remove your email, there's a way to fully lock out
your account:
1. Create account via NeoPass, so no password is set.
2. Ensure you have an email saved, then disconnect NeoPass.
3. Remove the email.
4. Now you have no NeoPass, no email, and no password!
In this change, we add a validation that requires an account to always
have at least one login method. This works well for the case described
above, and also helps offer server-side validation to the "can't
disconnect NeoPass until you have an email and password" stuff that
previously was only enforced by disabling the button.
That is, the following procedure could also lock you out before,
whereas now it raises the "Whoops, there was an error disconnecting
your NeoPass from your account, sorry." message:
1. Create account via NeoPass, so no password is set.
2. Ensure you have an email saved, so "Disconnect" button is enabled.
3. Open a new browser tab, and remove the email.
4. In the original browser tab, click "Disconnect".
Ah okay, if you leave the password field blank but don't have one set,
our simple `update` method gets annoyed that you left it blank.
In this change, we simplify the model API by just overriding
`update_with_password` with our own special behavior for the
no-password case.
including validation logic to make sure it's not already connected to
another one!
The `intent` param on the NeoPass form is part of the key! Thanks
OmniAuth for making it easy to pass that data through!
Ahh I see, if you do a no-op update, it still clears the
`previously_new_record?` state, so our NeoPass controller thinks this
account already existed. Instead, let's only do this update if it's an
account that already exists, instead of depending on the no-op-iness!
That is, you're required to add a password *or* an email before
disconnecting your NeoPass, but idk, I think it's rude to demand an
email from someone for the sake of *disconnection*. Email is no longer
required for accounts that already exist!
This is more consistent with the `uses_omniauth?` we already have, and
it also will help for the next change, where I want a `uses_password?`
method (and using the name `password?` breaks some of Devise's
validation code).
Previously, the way we loaded the image hash for a given pet was to
navigate to `https://pets.neopets.com/cpn/<pet_name>/1/1.png`, but
*not* follow the redirect, and extract the image hash from the URL
where it redirected us to.
In this change, we refactor to use the AMFPHP RPC `PetService.getPet`
instead. I don't think it had this data last time I looked at it, but
now it does! Much prefer to use an actual RPC than our weird hacky
thing!
(We might also be able to use this call for other stuff, like
auto-labeling gender & mood for pet states, maybe?? That's in this data
too! We used to load petlookups for this, long long ago, before the
petlookup captchas got added.)
I guess this was like, we had some call site that was handling loading
the viewer data itself, and didn't want to have to reload it?
But whatever, not used now, let's simplify! We can rebuild this easily
if we need it again.
Locale is the big one that's not really relevant anymore (I don't want
to be loading non-English item names anymore, now that we've simplified
to only support English like TNT has!), but there was also `item_scope`
and stuff.
The timeout option is technically not used in any call sites, but I
think that one's useful to leave around; timeout stuff is important,
and I don't want to rewrite it sometime if we need it again!
Just a small thing, I guess when I was a kid I did a weird thing where
I attached `origin_pet` to `PetType`, then upon saving `PetType` I
loaded the image hash for the pet to save as the pet type's new image
hash.
I guess this does have the nice property of not bothering to load that
stuff until we need it? But whatever, I'm moving this into `Pet` both
to simplify the relationship between the models, and to prepare for
another potential refactor: using `PetService.getPet` for this instead!
Ahh, I had assumed the `uid` provided by NeoPass would be the user's
Neopets username, but in hindsight that was never gonna work out since
NeoPass doesn't think of things in terms of usernames at all!
For now, we create 100% random NeoPass usernames, of the form
"neopass-shoyru-5812" or similar. This will be an important fallback
anyway, because it's possible to have a NeoPass with *no* Neopets.com
account attached.
But hopefully we'll be able to work with TNT to request the user's main
Neopets account's username somehow, to use that as the default when
possible!
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!)
Whew, exciting! Still done nothing against the live NeoPass server, but
we've got this fully working with the development server, it seems!
Wowie!!
This is all still hidden behind secret flags, so it's fine to deploy
live. (And it's not actually a problem if someone gets past to the
endpoints behind it, because we haven't actually set up real
credentials for our NeoPass client yet, so authentication will fail!)
Okay time to lie down lol.
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!
This is setting us up for NeoPass, but first we're just gonna try stuff
with the "developer" strategy that's built in for testing, rather than
using the NeoPass dev server!
When we moved more logic into the main app, we made some assumptions
about manifest art that were different than Impress 2020's, in hopes
that they would be More Correct for potential future edge cases.
Turns out, they were actually *less* correct for *current* edge cases!
Chips linked us to a few examples, including this Reddit post:
https://www.reddit.com/r/neopets/comments/1b8fd72/i_dont_think_thats_the_correct_image/
Fixed now!
Oh rough, when moving an item list entry from one list to another, our
logic to merge their quantities if it's already in that list was just
fully crashing!
That is, moves without anything to merge were working, but moves that
required a merge were raising Internal Server Error 500, because the
`list_id` attribute wasn't present.
I'm not sure why this ever worked, I'm assuming using `list_id` in the
`where` condition would include it in the `select` implicitly in a
previous version of Rails? Or maybe Rails used to have fallback
behavior to run a second query, instead of raising
`MissingAttributeError` like it does now?
Well, in any case, this seems to fix it! Whew!
Yay, we finally added it, the part where we include the appearance data
for the items based on both the species/color and the alt style! Now,
switching to Faerie Acara correctly filters the search only to items
that would fit (I think literally just only body_id=0 items right now,
but we're not banking on that!)
This only *really* shows up right now in the case where you construct
an Advanced Search form query (which only the wardrobe-2020 app does
now, and in limited form), and we return the query back (which only
gets used by the HTML view for item search, which doesn't have any way
to build one of these requests against it).
This is because, if you just type in `fits:alt-style-87305`, we always
keep your search string the same when outputting it back to you, to
avoid the weirdness of canonicalizing it and changing it up on you in
surprising ways!
But idk, this is just looking forward a bit, and keeping the system's
semantics in place. I hope someday we can bring robust text filter
and Advanced Search stuff back into the main app again, maybe!
I considered this at first, but decided to keep it simple until it
turned out to matter. Oops, it already matters, lol!
I want the item search code to be able to easily tell if the series
name is real or a placeholder, so we can decide whether to build the
filter text in `fits:$series-$color-$species` form or
`fits:alt-style-$id` form.
So in this change, we keep it that `AltStyle#series_name` returns the
placeholder string if none is set, but callers can explicitly ask
whether it's a real series name or not. Will use this in our next
change!
Previously we did this hackily by comparing the ID to a hardcoded list
of IDs, but I think putting this in the database is clearer and more
robust, and it should also help with our upcoming item search stuff
that will filter by it!
Previously, passing in `fits:blue` would cause a crash, because
`species_name` part of the split would be `nil`, oops!
In this change, we use a regex for more explicitness about the pattern
we're trying to match. We'll also add more cases next! (You'll note the
error message mentions `fits:nostalgic-faerie-draik`, which isn't
actually possible yet, but will be!)
I think this is a bit clearer and lets us clean up some of the syntax a
bit (don't need to always say `filters <<`), and also it will let us
use `return`, which I'm interested in for my next change!
Right, fitting isn't just body_id = this one, it's also body_id=0!
Anyway, doing this query on its own is still deathly slow, I wonder if
the idea I had about left joins (back when I was still working in a
Rails version that didn't support it lol) could help! Might poke at
that a smidge.
I feel like this was part of `will_paginate` back before the Rails
community had itself figured out about what belongs in a model?
But yeah, a default per-page value for search results does not belong
here. And I don't think anything references it anymore, because we pass
`per_page` to the `paginate` call in `ItemsController` explicitly! So,
goodbye!
First off, I think our code has converged on a convention of gracefully
returning `nil` for manifest-less situations, so we can do that instead
of raise! And then that lets us just simplify this check to whether
`manifest` is present, instead of `manifest_url`, so we stop crashing
in cases where we get to this point in the code and there's a manifest
URL but not a manifest.
This was a bit tricky! When I initially turned it on, running
`rails swf_assets:manifests:load` would trigger database errors of "oh
no we can't get a connection from the pool!", because too many records
were trying to concurrently save at once.
So now, we give ourselves the ability to say `save_changes: false`, and
then save them all in one batch after! That way, we're still saving by
default in the edge cases where we're downloading and saving a manifest
on the fly, but batching them in cases where we're likely to be dealing
with a lot of them!
Now we're *really* duplicating with Impress 2020's system lol, but I
need a way to not keep trying to load manifests that are actually 404,
which are surprisingly plentiful!
This doesn't actually stop us from loading anything yet, it just tracks
the timestamps and the HTTP status! But next I'll add logic to skip
when it was 4xx recently.
This is both unnecessary now, but also caused a bug in the new search
stuff where searching by zone would pass an extra `locale` argument to
a filter that doesn't need it!
Idk when this regressed exactly, but probably people didn't super
notice because I don't think it's a very common thing to type directly
into the Infinite Closet search box! (It used to be crucial to the old
wardrobe app.)
But I'm using it in the wardrobe app again now, so, fixed!
For now, I'm doing it with a secret feature flag, since I want to be
committing but it isn't all quite working yet!
Search works right, and the appearance data is getting returned, but I
don't have the Apollo Cache integrations yet, which we rely on more
than I remembered!
Also, alt styles will crash it for now!
`is:np` now means "is not NC and is not PB".
Note that it might be good to make NC and PB explicitly mutually
exclusive too? It would complicate queries though, and not matter in
most cases… the Burlap Usul Bow is the only item that we currently
return for `is:pb is:nc`, which is probably because of a rarity issue?
Adding new functionality to the item search JSON endpoint, and adding
an adapter layer to match the GQL format!
Hopefully this will be pretty drop-in-able, we'll see!
The alt styles controller is the one place we use this right now, but
I'm planning to generalize this to loading appearances during item
search, too!
I also add more `only` fields to the alt styles `as_json` call, because
idk it feels like good practice to both 1) say what we need in this
endpoint, rather than rely on default behavior upstream, and 2) to
avoid leaking fields we didn't realize were on there. (And also to
preserve bandwidth, too!)
I think there's no call sites for these anymore, so now I can start
repurposing these methods for the new API endpoints I'm planning! :3
Now, `SwfAsset#image_url` approximately matches Impress 2020 logic: use
the thumbnail PNG from the manifest if one exists, or the Impress 2020
converter for canvas movies, or the old AWS copy generated by gnash if
necessary, or return nil.
I think this used to be used in an API endpoint we've now deleted? I'm
just cleaning up call sites because I intend to refactor the `urls`
method and stuff, so I'm removing cruft that would complicate it!
I'm not certain-certain this is unused, but I did a global search for
`\bimages\b` in the codebase, and didn't find anything that looked like
a match to me!
Doing that sweet, sweet backfill!! It's not exactly *fast*, since
there's about 570k records to work through, but it's pretty good all
things considered! Thanks, surprisingly-reusable async code!
I'm gonna also use this for a task to try to warm up *all* the
manifests in the database! But to start, just a simple one, to prepare
the alt styles page quickly on first run. (This doesn't really matter
in production now that I've already visited the page once, but it helps
when resetting things in dev, and I think more it's about establishing
the pattern!)
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!
Preparing to finally move wardrobe-2020's item search to use the main
app's API endpoints instead!
One blocker I forgot about here: Impress 2020 has actual support for
knowing an item's true appearance, like by reading the manifest and
stuff, that we haven't really ported over. I feel like maybe I should
pause and work on the changes to manifest-archiving that I'd been
planning anyway? I'll think about it.
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?)
Okay, so I still don't know why rendering is just so slow (though
migrating away from item translations did help!), but I can at least
cache entire closet lists as a basic measure.
That way, the first user to see the latest version of a closet list
will still need just as much time to load it… but *only* the ones that
have changed since last time (rather than always the full page), and
then subsequent users get to reuse it too!
Should help a lot for high-traffic lists, which incidentally are likely
to be the big ones belonging to highly active traders!
One big change we needed to make was to extract the `user-owns` and
`user-wants` classes (which we use for trade matches for *the user
viewing the list right now*) out of the cached HTML, and apply them
after with Javascript instead. I always dislike moving stuff to JS, but
the wins here seem. truly very very good, all things considered!
This one is important, I didn't notice that this is a way of setting
attributes that won't be written to both tables! `name` will only be
written to the translation table (which crashes the save), and the
other fields would only be written to the main table. Fixed! (I don't
like the super-dynamic this code was written before, anyway.)
Missed this at first - now that the `name` field is just a normal field
and is always English, it's now an error to provide the locale to it as
a parameter, like we used to for the translated version of the field!
Like with Species, Color, and Zone, we're moving the translation data
directly onto the model, and just using English. This will simplify
some of our queries a lot (way fewer joins!), and it's what Neopets
does now anyway, and I have a secret hope that removing the complexity
along the codepath for `item.name` might help speed up large item lists
if we're lucky?? 🤞
Anyway, this is the first step, performing the migration to copy the
data onto the `items` table, making sure to keep them in sync for the
2020 app for now!
Tbh I'm not sure `special_color` is actually used anywhere? It used to
be how we decide what to show in the previewer on the item page, but
that's been replaced with the 2020 logic, so idk…
But in any case, I noticed that the description doesn't match the
pattern we have, so here's the fix!
I looked at this and was like. "ok literally what is
`nonstandard_colors` trying to do"
reading it again now, I'm realizing the idea is that it probably runs
two queries: one to get nonstandard colors, then depends on
ActiveRecord to implicitly convert the relation to an array and then to
IDs for the second query? Instead of doing a join??
Idk, it's unused, so trash it!
This used to be the behavior, and the site has plenty of graceful
fallbacks for it, I just forgot this one when doing Rails upgrades!
Note that the impress-2020 stuff is *not* as graceful about this, so
the wardrobe page won't show the pet until the color is in the DB. Ah
well, still an improvement!
Okay right, the wardrobe-2020 app treats `state` as a bit of an
override thing, and `pose` is the main canonical field for how a pet
looks. We were missing a few pieces here:
1. After loading a pet, we weren't including the `pose` field in the
initial query string for the wardrobe URL, but we _were_ including
the `state` field, so the outfit would get set up with a conflicting
pet state ID vs pose.
2. When saving an outfit, we weren't taking the `state` field into
account at all. This could cause the saved outfit to not quite match
how it actually looked in-app, because the default pet state for
that species/color/pose trio could be different; and regardless, the
outfit state would come back with `appearanceId` set to `null`,
which wouldn't match the local outfit state, which would trigger an
infinite loop.
Here, we complete the round-trip of the `state` field, from pet loading
to outfit saving to the outfit data that comes back after saving!
Now that DTI 2020 has been deployed without references to the
translations tables, we can stop keeping them in sync!
Next step is to drop the tables and be done with them altogether! (I
have a backup of the public data for this too, as does this repo!)
Two motivations here:
1. Unconverted pets should no longer exist on Neopets.com (and we
especially don't expect new ones), so this logic helps no one.
2. The Baby Pteri keeps getting overridden to be marked as Unconverted
because it has only one asset, which is incorrect.
A decent heuristic for a bygone era, goodbye!
Yay it works(*)! But two major missing pieces:
- Outfit saving doesn't persist it at all
- Item compatibility is unaffected: items will still appear in search
and in the preview, even when they don't fit anymore.
To help with space, I'm just showing the word "Nostalgic" (or "???" if
it's from a series we don't recognize, this is hardcoded by ID), and
trusting that from context it will be obvious that it's the "Nostalgic
Faerie" case or whatever. (Moreover, in both the button and the select
we're omitting the species name, by similar reasoning!)
Note that this _still_ doesn't actually apply the style to the outfit
whatsoever; this is all just local state as we're continuing to play
with UI concepts. Actually applying it is probably next though! (Though
there's a couple more UI things I want to do, like some affordances to
clarify that a Style is applied and that Expression changes won't work.)
Something in the Rails loader doesn't like that I have both a gem and
a lib folder named `RocketAMF`, I think? It'll often work for the first
pet load request, then on subsequent ones say `Envelope` is not
defined, I'm guessing because it scrapped the gem's module in favor of
mine?
Idk, let's just simplify all this by making our own module. I feel like
this old lib could use an overhaul and simplification anyway, but this
will do for now!
Like in 0dca538, this is preliminary work for being able to drop the
`zone_translations` table! We're copying the field over first, to be
able to migrate DTI 2020 safely before dropping anything.
Non-English languages haven't been supported on Neopets for a while, so
I'd like to remove this extra cross-cutting complexity, especially
since it's now inconsistent with the real site anyway!
The main motivation is that I'd like to do this for items too, because
I have a hunch that all the complexity of `globalize` to read
`item.name` is part of what's making large user lists so slow to
render: lots of little objects getting created down the stack, and
needing to be garbage-collected later.
I'm not sure that's why! But I figure removing this complexity is a
simplicity win anyway, so let's do it!
Note that this doesn't *finish* the migration, it just starts it! The
`Species::Translation` and `Color::Translation` models still exist, and
still have their data, and not all references to them are scrubbed yet.
I especially don't want to delete the backing tables until both DTI and
DTI 2020 are ready for it!
So this change will someday be paired with another change to actually
drop the tables - after backing up the data for future records just in
case, of course!
If your first wanted list was created before your first owned list,
then `false` would come before `true` in the keys of
`current_user_lists`.
I both fixed this to be more consistent at the model level, because who
likes unpredictable behavior? But also downstream at the view I
hardcoded that true should come before false, because that's a UI
concern that I want to be encoded in the view regardless of what's
upstream.
It was a bit tricky to figure out the right API for this, since I'm
looking ahead to the possibility of splitting these across multiple
pages with more detail, like we do in DTI 2020.
What I like about this API is that the caller gets to apply, or not
apply, whatever scopes they want to the underlying hanger set (like
`includes` or `order`), without violating the usual syntax by e.g.
passing it as a parameter to a method.
Ahh I see, the way we got away with not having a `trading` scope before
was a weird metaprogramming `{owned/wanted}_trading` situation. Okay,
let's trash that in favor of our new stuff! And that helps us bulk the
queries too which is nice.
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! 🤞
So this was a slightly wrong error message, what was happening was:
1. Trying to load the image hash for this pet, by looking them up at
https://pets.neopets.com/cpn/PET_NAME/1/1.png and seeing what URL it
redirects to.
2. But pets.neopets.com was rejecting our User-Agent string, which
would've been just "Ruby", since we hadn't set it otherwise. I guess
that's an explicitly banned string?
I also found that the kind of more-helpful User-Agent string I like to
write was being rejected, and I could only get it to accept something
very simple? So that's what we're using now, I guess!!
Building toward replacing more of the 2020 data sources! I think this is
an endpoint that benefits from bulk loading, esp with the way the item
page previews work. I also like taking the concept of "canonical" out of
the GQL interface, and instead just loading for each of the 50 species
and letting the client decide. (And then it can fast-swap between them!)
The models folder is a bit confusingly large, these are more mixins and
kinda clutter it. Push them off into `lib`, I think!
I think they used to be in models mainly because Rails used to handle
`lib` differently with autoloading, and it made for a worse dev
experience. Now it's all the same, though!
We haven't used the mall spider in this app in forever (I guess we even
deleted the code at some point?), but there was some vestigial stuff
left. Goodbye!
Just moving more stuff over! I modernized Item's `as_json` method while
I was here. (Note that I removed the NC/own/want fields, because I
think the only other place this method is still called from is the
quick-add feature on the closet lists page, and I think it doesn't use
these fields to do anything: updating the page is basically a full-page
reload, done sneakily.)
There was a time when I used an old proxy server to try to fix mixed
content issues, and I eventually removed it but never took the tendrils
out from the code.
We probably _should_ figure out how to secure these URLs! But until
then, we may as well simplify the code.
I changed my mind again! At first I wanted to make the special case
clearer, and to be able to more strongly assert that the species is
not null. But now I'm like… eh, there's code that references `body.id`
that has no reason _not_ to work in the all-bodies case… let's just
keep the types more consistent, I think.
This is more similar to what impress-2020 does, I was working on the
wardrobe-2020 code and took some inspiration!
The body has an ID and a species, or is the string "all".
Preparing a better endpoint for wardrobe-2020 to use! I deleted the
now-unused swf_assets#index endpoint, and replaced it with an
"appearances" concept that isn't exactly reflected in the database
models but is a _lot_ easier for clients to work with imo.
Note that this was a big part of the motivation for the recent
`manifest_url` work—in this draft, I'm probably gonna have the client
request the manifest, rather than use impress-2020's trick of caching
it in the database! There's a bit of a perf penalty, but I think that's
a simpler starting point, and I have a hunch I'll be able to make up
the perf difference once we have the impress-media-server managing more
of these responsibilities.
Ok so, impress-2020 guesses the manifest URL every time based on common
URL patterns. But the right way to do this is to read it from the
modeling data! But also, we don't have a great way to get the modeling
data directly. (Though as I write this, I guess we do have that
auto-modeling trick we use in the DTI 2020 codebase, I wonder if that
could work for this too?)
So anyway, in this change, we update the modeling code to save the
manifest URL, and also the migration includes a big block that attempts
to run impress-2020's manifest-guessing logic for every asset and save
the result!
It's uhh. Not fast. It runs at about 1 asset per second (a lot of these
aren't cache hits), and sometimes stalls out. And we have >600k assets,
so the estimated wall time is uhh. Seven days?
I think there's something we could do here around like, concurrent
execution? Though tbqh with the nature of the slowness being seemingly
about hitting the slow underlying images.neopets.com server, I don't
actually have a lot of faith that concurrency would actually be faster?
I also think it could be sensible to like… extract this from the
migration, and run it as a script to infer missing manifest URLs. That
would be easier to run in chunks and resume if something goes wrong.
Cuz like, I think my reasoning here was that backfilling this data was
part of the migration process… but the thing is, this migration can't
reliably get a manifest for everything (both cuz it depends on an
external service and cuz not everything has one), so it's a perfectly
valid migration to just leave the column as null for all the rows to
start, and fill this in later. I wish I'd written it like that!
But anyway, I'm just running this for now, and taking a break for the
night. Maybe later I'll come around and extract this into a separate
task to just try this on all assets missing manifests instead!
Ahh, I guess I missed these, I think they're maybe not actually used in
the app is why? cuz they're all default values that are overridden at
the actual call sites. But I ran into it when running `Pet.load` in the
console, and yeah let's just fix 'em up!
This hasn't worked for a while, and I don't know an API off the top of
my head to drop in for it. Let's just delete it for now, and revisit it
later if we want to!
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*
