To activate this, I created a `.env.development` file in my project
root, with the following content:
```env
IMPRESS_2020_ORIGIN=http://localhost:4000
```
Then, I started impress-2020 with `yarn dev --port=4000`.
Now, the app loads from there, hooray!! It even fixes that obnoxious
pet state ID bug that happens when you run against the production db lol
Using good ol'-fashioned cookies! The JS sets it, and then Rails reads
it on pageload. That way, there's no flash of content for it to load in
after JS loads.
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.
Oh yeah, a long-standing limitation. Good thing we're better at stuff
now!
This is also probably the real cause of the weird number of slight
discrepancies between main DTI and DTI 2020 when I eyeballed stuff lol
oh, well, that and the missing default-lists. A bit messy!
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.
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!
Now, like in DTI 2020, opening an outfit will go straight to the editor.
I'm not 100% on whether this is actually like. the superior behavior?
But I think it's good enough, and it's what the wardrobe-2020 code
expects, so let's just roll with it for now!
I hope this doesn't cause problems! But yeah, with Puma doing threading, and maybe switching to Falcon someday to get even better concurrency properties, I feel like this will probably be fine?
And it makes the UX a loootttt better, to be back in the world where all these forms just work, whew.
In the login case, we save the `return_to` parameter in the session, because login can be a multi-step process.
In the logout case, we just read it directly from the form params.
Note that you *could* end up in a weird scenario where an old return_to value sticks around for a bit? But we have the sense to delete it when we use it on a successful sign-in, and most links to the login page come with a `return_to` param which should reset it. So, you'd have to 1) have started but not finished a sign-in, 2) during the same session, and 3) get to the login page by an unusual means.
Probably fine!
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.
Whew! Seems like a pretty clean one? Ran `rails app:upgrade` and stuff, and made some corrections to keyword arguments for `translate` calls. There might be more such problems elsewhere? But that's hard to search for, and we'll have to see.
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!
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.
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.)
Tbh I'm not 100% sure this is a fix, I'm not sure what `haml_concat` was doing here, and the page is still crashing so it's hard to say. But fingers crossed!
The controller was like "oh yeah we have that cached" (from previous renders of the app on Rails 3 I think?), but the view disagreed, bc it was appending a template digest to the cache key. That's a smart feature, but not compatible with how we skip queries in the controller, so disable it for now!
We recently flipped the switch for various hosts to force HTTPS, yay! This includes `neopia.openneo.net`.
However, I forgot to change the URL scheme in this file. This meant that the form submit from the homepage would go to `http://neopia.openneo.net/`, then redirect to `https://neopia.openneo.net/`, but only preserve the form data in certain browsers. This change should fix that!
Note: This probably breaks the dev environment, where we don't have a cert for `https://neopia.dev.openneo.net`. I'll fix that some other time!
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.
This is a surprisingly huge performance gain. On my testing (with
cache_classes set to true to also cache templates), this sped up
closet_hangers#index rendering by a factor of 2 when there were a
significant number of items. Cool beans.
I think we can even hold off on the individual hanger caching now:
we've made the closet hanger partial tons faster by moving forms out
of them and doing this cache check earlier. I'm expecting significant
performance gains both here and on items#index (though less so there).
I'll deploy and see how much it helps in production; if not enough, we
can look at the layered caching of hangers, lists, groups, full pages,
etc.
So glad we don't *have* to move to a pagination model!
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.
This one was actually pretty darn clever - nobody's abused it, but
I was reading a blog post where someone described this type of
issue, I realized it was a brilliant attack, and then realized
DTI was vulnerable. Oops. Thanks for the solution, Jamie!
