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*
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.
Okay so, userlookup stuff hasn't worked in years, because it requires a login now.
But apparently, somewhere recently, the code inside our `neopets` gem started hard crashing, because of assumptions we made about the document we'd get back.
I'm not sure why it only recently started crashing? or if I'm even necessarily right about that?
But anyway, I'm just doing the easiest safest (🤞🏻) change possible: being more generous with the errors we swallow.
Test Plan:
Deploy and cross fingers.
Okay, fine, finally making this controllable from the db without requiring a deploy :P Setting this new field will cause `item.special_color` to return the corresponding color. This mainly affects what we show on the item page, and what colors we request for modeling on the homepage.
Interestingly, these items *are* correctly detecting their special
color on the homepage for model progress. So, we *do* have the ability
to detect this. But I don't have good item data locally, so it would
be hard to test this, so I'm just gonna go with the cheap solution
again, sorry XP
In bfd825d, we refactored the "is item body-specific?" check. In the process, we dropped the check for the manual override flag, `explicitly_body_specific?`. Not sure if it was an accident or if I was just _so_ confident that it was gonna work :P In any case, re-add the check!
Okay, surprise, the bug was unrelated to Camo config (though I'm glad I cleaned
that up anyway :P). We now, at a low level, serve a placeholder image for item
thumbnail URL if, for some reason, we don't have a good thumbnail URL on hand.
One time I did a thing called Camo to try to get our HTTPS pages working,
because images.neopets.com not supporting HTTPS is crazy >_> I've diasbled it
these days, but it had debug behavior to append `?NO_CAMO_CONFIG` to all
proxied URLs when Camo was not configured.
When an item had no thumbnail URL for some reason (mall spider needs fixing,
maybe?), this caused Rails to try to map that empty string into the path
`/assets/?NO_CAMO_CONFIG`, which made Rails complain that it was trying to load
an asset that doesn't exist. This is probably a sign that using `image_tag` for
URLs that *should* be external URLs, but aren't strictly *guaranteed* to be, is
unwise - but, for now, I've just disabled that behavior. I hope Rails has a
better escape hatch for the empty string :P
Ooh, this one was nasty, and only one symptom ever got noticed:
1. Pick "Occupies: Collar" in Advanced Search.
You get the text query "occupies:necklace".
2. And, if you try to do "occupies:collar" even in text-based search,
you *also* get the results from "occupies:necklace" mixed in with
the correct results.
The trick is that, in Spanish, zone 24 (necklace) is named "collar",
as is zone 27 (collar). Not sure what to do for Spanish, but this
issue also leaked into English: we really don't want English to return
results for Spanish-named zones.
This is a tricky problem, though, because it'd be nice for es users
to be able to type "occupies:hat". I think we'll have to do the quick
fix for now, though, and just only interpret the query in the current
locale.
I've been doing this manually via email for a long time,
since building new stuff in the logged-in world was a pain in the old env.
But now here we are! Finally, finally :)
The "fits:8-bit-chomby" search filter was being read as color=8, species=bit.
Now, we split from the right-hand side of the filter instead.
Still a problem for anyone who explicitly types the Spanish/Portuguese
ordering of "fits:chomby-8-bits", but I'm okay with this cheap fix, since
I bet literally nobody has done that in the past month, if ever :P
In particular, outfit_id == 0 would cause outfit_id? to
return false, so it wouldn't run the outfit presence
validation, so /donations/features would try to load
outfit #0 and fail.
Also, flash[:alert] instead of flash[:error] when outfit_id
is bad.
It turns out that some pets for seemingly nonstandard colors have the
standard body type anyway, and vice-versa. This implies that we should
stop relying on a color's standardness, but, for the time being, we've
just revised the prediction model:
Old model:
* If I see a body_id, I find the corresponding color_ids, and it's wearable
by all pet types with those color_ids.
New model:
* If I see a body_id,
* If it also belongs to a basic pet type, it's a standard body ID.
* It therefore fits all pet types of standard color (if there's
more than one body ID modeled already). (Not really,
because of weird exceptions like Orange Chia. Should that be
standard or not?)
* If it doesn't also belong to a basic pet type, it's a nonstandard
body ID.
* It therefore only belongs to one color, and therefore the item
fits all pet types of the same color.
We used get_multi when preparing the proxies to decide which to
load from the database, but then sent multiple get requests to
Memcache to re-fetch the same data from that get_multi. Silly!
Use the data that's already stored on the proxy anyway.
Right now we're spending too much time expiring cache keys when
getting contributions. The longer-term fix is to move it to a
background task, but it's good to restrict deletions only to usable
locales rather than all the ones that Rails theoretically supports.
Some lame benchmarking on my box, dev, cache classes, many items:
No proxies:
Fresh JSON: 175, 90, 90, 93, 82, 88, 158, 150, 85, 167 = 117.8
Cached JSON: (none)
Fresh HTML: 371, 327, 355, 328, 322, 346 = 341.5
Cached HTML: 173, 123, 175, 187, 171, 179 = 168
Proxies:
Fresh JSON: 175, 183, 269, 219, 195, 178 = 203.17
Cached JSON: 88, 70, 89, 162, 80, 77 = 94.3
Fresh HTML: 494, 381, 350, 334, 451, 372 = 397
Cached HTML: 176, 170, 104, 101, 111, 116 = 129.7
So, overhead is significant, but the gains when cached (and that should be
all the time, since we currently have 0 evictions) are definitely worth
it. Worth pushing, and probably putting some future effort into reducing
overhead.
On production (again, lame), items#index was consistently averaging
73-74ms when super healthy, and 82ms when pets#index was being louder
than usual. For reference is all. This will probably perform
significantly worse at first (in JSON, anyway, since HTML is already
mostly cached), so it might be worth briefly warming the cache after
pushing.
That is, once we get our list of IDs from the search engine, only
fetch records whose JSON we don't already have cached.
It's simpler here to use as_json, but it'd probably be even faster
if I figure out how to serve a plain JSON string from a Rails
controller. In the meantime, requests of entirely cached items
are coming in at about 85ms on average on my box (dev, cache
classes, many items), about 10ms better than the last
iteration.
Specifically, we were running a find_or_initialize_by for all 50
hangers, which isn't great. Collation logic is more complicated this
way, but query count is way lower.
Additionally, compare against hanger.list_id instead of hanger.list,
because hanger.list will fire a query if list_id is non-nil, but that
nil ID tells us everything we needed to know, anyway.
Bug report that this resolves:
...However, when I was using the "Import from SDB" tool just a few
minutes ago, it ended up adding EVERY neocash item into the "Not
In A List" section, regardless if I already that item imported
into my "Your Items". So, basically.. I had duplicates of
everything and it would not allow me to move them around into
separate catergories or anything. I know that every other time i've
used the import tool, it would only add NEW items that are not
currently already in my lists yet.
Most of the reasoning is documented in the big comment. In short, we tried
to solve the problem with caching, but the caching should hardly be necessary
now that the bottleneck should be fixed. We'll see on production if it
actually solves the whole problem, but I've confirmed in the console that
redefining this function makes random_basic_per_species (as called during
rendering) a ton faster. And this way we keep our randomness, woo!
TNT has started serving half-removed Corridor of Chance effects:
it has the asset ID and URL and all, but the zone ID is blank.
RocketAMF has patched the empty key bug, and now we ignore assets
associated with empty keys.
Specifically, the Tyrannian Meerca Spear is a pb item that contains
"pea", so its item page is only willing to show a Pea Chia. Now,
a color must be a whole word in the item name for special color
determination to work.
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.
We were joining to the translations table to sort records
alphabetically, but then it sorted by *all* of the translations in
some strange way. Now use with_translations to restrict the join
to the current locale.
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.
We originally had a regression on name-matching, where, among
other issues, `straw hat` returned items containing both "straw"
and "hat", which isn't really helpful behavior since we're sorting
alphabetically. Now, `straw hat` behaves as expected.
Additionally, "phrases like these" behave as expected, too.
Confirmed features:
* Output (retrieval, sorting, etc.)
* Name (positive and negative, but new behavior)
* Flags (positive and negative)
Planned features:
* users:owns, user:wants
Known issues:
* Sets are broken
* Don't render properly
* Shouldn't actually be done as joined sets, anyway, since
we actually want (set1_zone1 OR set1_zone2) AND
(set2_zone1 OR set2_zone2), which will require breaking
it into multiple terms queries.
* Name has regressed: ignores phrases, doesn't require *all*
words. While we're breaking sets into multiple queries,
maybe we'll do something similar for name. In fact, we
really kinda have to if we're gonna keep sorting by name,
since "straw hat" returns all hats. Eww.
For example, the Meerca Maid Tray is a foreground item, so the SWF is marked
as compatible with all body types, but the item itself is clearly marked as
Meercas-only. items#show reflected this properly, but the swf_assets#index
call that the wardrobe uses ignored item.species_support_ids.
So, /bodies/:body_id/swf_assets.json?item_ids[]=... was deprecated in favor
of /pet_types/:pet_type_id/items/swf_assets.json?item_ids=[]..., which is
much like the former route but, before loading assets, also loads the pet
type and items, then filters the items by compatibility, then only loads
assets for the compatible items.
