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!
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!
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!
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!
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*
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
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!
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?)
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.
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.)
A few key changes:
* Don't reload the whole pet 8 times!! Sooo many bad things
happen, including redundant lookups of everything else and
too many item saves and reindexes. Instead, fetch the item
data, apply it to the items, and then save the items (once
each!)
* Updated my branch of globalize3 to be even better at avoiding
redundant queries when saving. Woo.
* Last realization: wrapping all the item saves in a single
transaction works wonders. COMMIT seems to have high overhead,
so doing only one took it from 50ms * 10 or whatever to 60ms.
Good stuff.
In particular, pet#load was handling locale-switching itself, but wasn't
switching back to original locale on error. We could've used a rescue
block, but, when I18n.with_locale is so cool, may as well use it fully.
