Nice, gotta say, this is a pretty neat way of making things feel more
app-y! There's some missing pieces here about like, loading state etc,
but the vibes are pretty good, and the implementation was dead-easy!
Just stripping out the big React component, and having Rails output it!
There's a lot of work rn in extracting the Impress 2020 dependency from
the `wardrobe-2020` React app, and I'm just curious to see if we can
simplify it at all by pulling this stuff *way* back to basics, and
deleting the item page part of `wardrobe-2020` altogether.
In this draft, we regress a lot of functionality: it just shows the
item on a Blue Acara, with no ability to change it! I'm gonna play with
putting more of that back in.
I also haven't actually removed any of the item page React code; I just
stopped calling it. That can be a cleanup for another time, once we're
confident in this experiment!
Oh huh, TIL in Ruby `^` *always* means "start of line", whereas in many
languages' regular expression engines it means "start of string" unless
you enable a special multiline flag for the pattern.
I've fixed this in a number of expressions now!
I'm noticing this in the context of doing some security training work
where this the cause of a sample vulnerability, but, looking at our own
case, I don't think there was anything *abusable* here? But this is
just more correct, so let's be more correct!
Ahh, I started a tabs-y file (as I default to these days), but copied
code from a spaces-y file, and didn't notice. (My laptop editor isn't
configured to flag this for me, oops!)
Fixed!
This doesn't affect a lot right now, it was previously defaulting to
UTC I think? And I've confirmed that, while timestamps are stored in
the database as UTC, they're not interpreted any differently with this
setting. (Or, rather, it's loaded as a `DateTime` object for the same
moment in time, but in the NST time zone. Good!)
But this feels like a more useful default for displaying things for
development etc, and moreover, I'm working on some logic for things
like "when do limited-time Dyeworks items expire exactly?", and that
logic is made *much* simpler if we can just compare dates in NST by
default rather than fudge around with the zones on them and figuring
out the correct midnight!
(Although, as I type this, I think I maybe have thought of an easier
way to do it? So maybe this change won't actually be necessary for
that, but it still feels like a more sensible default for us
regardless!)
There's just starting to be a lot going on, so I pulled them out into
here!
I also considered a like, `Item::DyeworksStatus` class, and then you'd
go like, `item.dyeworks.buyable?`. But idk, I think it's nice that the
current API is simple for callers, and being able to do things like
`items.filter(&:dyeworks_buyable?)` is pretty darn convenient.
This solution lets us keep the increasing number of Dyeworks methods
from polluting the main `item.rb`, while still keeping the API
identical!
Oh this was a fun little dev environment bug: I ran `public_data:pull`
on my laptop before migrating my database, so the `items` table pulled
as the latest production version, which included the migrations, but
they hadn't been marked as "run" yet.
So Rails was still telling me I needed to run them, but the migrations
themselves were crashing, with stuff like "there's already a column
with this name!"
This change ensures that `public_data:pull` won't run until migrations
are done, to prevent silly accidents like that.
Silly mistake, right, we might not have a trade value listed! This is
relevant for the new Dyeworks items that just came out like a few hours
ago, which Owls doesn't have info for yet.
Lmao I've been testing with an outfit that has all the kinds of items,
so I didn't notice that this new refactor to `@items[:dyeworks]` style
of tracking the items returns `nil` when there's none, instead of `[]`.
(I always make this mistake when I use `group_by` lmao sob)
In this change, we give the `@items` hash a default value, so that will
stop happening!
Oh right, this previously logic was silly: we can't count on the
*interval itself* to be reliably resetting the FPS counter state,
because the interval might not be firing!
I think this fix worked when I tried brief tests, but didn't work when
I did an (accidental) longer test, because the browser switched to a
more aggressive throttle mode, and the previous mode was close enough
on the resets for it to be fine, whereas this time the FPS counter
state got way too old.
Now, we reset the FPS counter state *exactly* when the page comes back.
We have a feature to check the movie's FPS, and pause it if it gets too
low, as a guard against especially low-performance movies. But this was
triggering in an *expected* case, where browsers intentionally throttle
interval events when a page is in the background (e.g. you switch to
another tab).
Now, our rendering is aware of page visibility: when the page is
hidden, don't bother rendering, and keep resetting the FPS counter
state, so that we can pick up with a fresh FPS counter when the page
comes back.
This doesn't matter-matter, it's mostly just so that when we SSH into
the production machine, the prompt presents itself as `impress` rather
than as `localhost`!
Oh weird, even with `flush: true`, `content_for` will ignore an empty
block and *not* flush out the previous content. This could cause rows
whose subtitles *should* have been empty (e.g. no NC trade value) to
display the previous row's value instead.
Let's make this whole situation a bit more robust by having the
*template* clear out the subtitle right before calling the block. That
way, a previous row's value *can't* get in, no matter what.
I think it helps a bit to have only the label be dotted-underlined, to
hint that I'm offering help about what that *means*, but clear the way
for the value itself to be more visible and less cluttered.
I thought to myself, "I wonder if it's possible to use a sneaky hacky
`content_for` trick to be able to run this code in the template." And
indeed it is!
It's tricky cuz like, I want to render this template, and I want to
provide _multiple_ slots of content to it. So, in this variant, we keep
the block as being primarily for the actions, but also optionally
accept `content_for :subtitle` inside that block, too.
Executing that correctly is a bit tricky! The subtitle comes *before*
the actions. So, we `yield` the actions block immediately, save it to a
variable, and *then* get the subtitle block.
Previously, I added a Dyeworks section that was incorrect: the base
item being available in the NC Mall does *not* mean you can necessarily
dye it with a potion!
In this change, we lean on Owls to tell us more about Dyeworks status,
and only group items in this section that Owls has marked as "Permanent
Dyeworks".
We don't have support for limited-time Dyeworks items yet—I've sent out
a message asking the Owls team for more info on what they do for those
items!
I started writing this up, then sent a preview to a friend, and he was
like "oh cool, but also this is not correct?"
I didn't realize Dyeworks has limited-time support to be *able* to dye
certain items. Hey, glad we're writing this guide for people like me,
then! lol
I wonder if we can lean on Owls for this. It seems like they already
list "Permanent Dyeworks" for some items, I wonder if they say
something special for active limited-edition Dyeworks items!
In this change, instead of *always* inferring the Dyeworks base item
from the item name at runtime, we now have a database field that tracks
it, and auto-populates whenever an item *seems* to need a Dyeworks base
item but doesn't have one yet.
This will enable us to set the base item manually in cases where it
can't be inferred, and load Dyeworks base items for the Item Getting
Guide in one query with `includes(:dyeworks_base_item)`.
This migration does a bit more of the fix-em-up scripting work *in* the
migration itself than I usually do, mainly because there's so much in
this one that I think being extra-explicit is useful. We make sure to
do it gracefully though!
This works for most of the current 1,094 Dyeworks items! But there are
a few exceptions, for cases where the base item name is not quite the
same (e.g. the Dyeworks version is more concise). Maybe we'll add a
database field to override this?

We could do a whole thing about like, checking singular vs plural, but
I'd rather just keep it simpler; I think it's clear from context that
we're talking about a category, so plural is fine even if it's not
actually more than one.
Okay so, like 30 minutes ago I added fallback behavior for cases where
we can't correctly infer the color from a PB item's name… and then I
pulled it up in the color and found that, oh, right, there are already
3 PB items that *correctly* return `nil` for `Item#pb_color`: Aisha
Collar, Elephante Hat, and Ixi Collar.
This is because they're common items that apply to many colors, like
the basics, but also many other less-special or older color variants.
They are the most likely case where we'll return `nil`.
So, I've updated our fallback UI to, instead of talk vaguely about
missing data, just assume that we're dealing with basic items. In the
rare window of time where a new color is released, and we have PB items
for it but no manual color data yet, this can just incorrectly say
"Basic Colors" and that's fine.
This is less likely than the newly-released color case for PB items,
but I figure let's be resilient anyway, especially since it's so easy
to—and also I figure this is less likely to be triggered by an *actual*
new species, and more likely to be triggered by a surprise in an item's
naming conventions.
But yeah, if `Item#pb_species` returns `nil` upstream, it'll be passed
to `Color#example_pet_type`, which will crash trying to read its ID. So
in this change, we update `Color#example_pet_type` to accept a `nil`
value, and fall back to the first Species (Acara) in that case.
This means that, if you e.g. take the Mutant Aisha Collar and delete
the word "Aisha" from the name, then load it in the Item Getting Guide,
you'll see a thumbnail of a Mutant Acara. Good enough!
Oh right, it's possible for `Item#pb?` to return true, but
`Item#pb_color` to return `nil`, if the item has the paintbrush item
description but we can't find a color whose name matches the item name.
This would be expected if a new color were added to Neopets, and PB
items for it were modeled by the community, but we hadn't manually
added the color to the database yet.
Previously, the Item Getting Guide would crash in this scenario. Now,
it correctly handles the possibility of a `nil` value for `pb_color`,
and shows some placeholder info.
To test this, I temporarily edited some item names to not contain the
color name anymore (e.g. "P-rate Elephante Shirt and Vest"), then
loaded the guide and made changes until it no longer crashed.
Oh huh, I guess we used to use this for automated testing, but since
then I've moved the test database to just be in MySQL like everything
else, so I think we don't need this adapter anymore! Goodbye!
I noticed in the app that these queries were slowwww! I was able to
track it down to a bad query plan, as we explain in the comment.
I searched online for "mysql query performance filter on one join table
sort by another", and was surprised to find this answer suggest a
subquery, which I've often been told to expect to be slower compared to
joins? But it certainly worked in this case!
https://stackoverflow.com/questions/35679693/mysql-optimize-join-with-filter-and-order-on-different-tables
I am. Kinda surprised we didn't have this already, huh?? I guess in
most searches, the difference isn't very noticeable, because we don't
have a lot of item names to sort anyway? But we do this *so often* that
I think an index will certainly help! Let's add it!
Oh whoops, I was symlinking to the *full* path of the latest dump,
which includes the site version directory in it. This meant that, if 5
new versions of the app were deployed since the most recently public
data commit (and so that version is deleted), the symlink fails.
In this change, we just symlink to the filename, which behaves as a
relative path and should be completely resilient to deploys changing
where these files ostensibly live!!
I think the Rails query cache handled these anyway? But `SwfAsset` has
a `before_save` hook that checks its zone's info, and
`SwfAsset.preload_manifests` saves all the assets, on the assumption
that saving is a no-op when the record didn't change anyway. And it
basically is!
But I figure that, now that I'm realizing hooks exist, simply not
attempting to save unchanged records is probably a better
representation of what we intend to do. So I'm fixing it like that!
Another potential fix would be to preload the zones for these assets,
but I think that confuses the intent too much; the method itself isn't
using the zones, it's just a weird incidental thing that a save hook
happens to use. (Would probably be better to refactor this old save
hook into a different situation altogether, but that's for another
time!)
