Instead of defining the function with an internal if that will always
pick the same path, let's use that if to instead define a
straightforward function that just does what we want.
Since meta.status would be undefined for an incomplete request,
I would have to check response.completed && response.meta.status,
which is too much burden. Let's set the status immediately, and
if a callback wants to do further diving we'll use completed then.
- tag_autocomplete.tags and .synonyms are separate vars, not in tagset.
- tag_autocomplete.tags is now a Set object for faster resolve().
- get_all_tags moved to api.js.
- server provides "updated" timestamp with the all_tags list.
The current system has bad performance when you've got 100,000+ tags.
I discovered that when the server returns 304, the browser gives the
ajax a 200 with the full response, and it's not clear to me if js can
know it got a 304. So, the tag set is being fully re-parsed from the
response on every page load. I was thinking that I should store that in
IndexedDB to avoid the parsing step, but... since the JSON.parse is
done by my common.get before it hits this function, it's meaningless.
Not to mention I still have to rebuild the datalist on every page since
of course that state isn't shared between tabs. Not worth the DB stuff.
We'll see what happens next.
I'm having some performance issues with button_with_confirm on /tags.
This won't magically make that faster but I'm trying to stop the main
thread from dragging at least.
Following the previous commit about the checkbox on the /photo page,
this fixes all of the code assuming that we're dealing with photo_card
divs, the majority of which was doing nothing but accessing the id.
