Search hangs and fails out when entering input too fast #7

Closed eastwood closed 4 years ago

eastwood commented 4 years ago

I've noticed that the ivy-interface for searching is very slow and hangs quite a bit when entering input. It feels like a synchronous call to spotify on each character. There also seems to be a bit of a race condition when you enter a string too fast either:

  1. Characters are missing
  2. The window crashes

I can provide a screen recording on request.

I'm happy to look into fixing this, but wanted to validate whether this is confirmed behaviour first

Hey! Well, you are correct, it calls the Spotify API synchronously on each character. I didn't know how to make asynchronous calls with Emacs when I first made this package, and never revisited it either. If you want to write some elisp I would gladly help you with everything you need, it's a thing that I had in mind but never got around to actually code it :sweat_smile:

I had some time this weekend and could address this issue. There was an Ivy new version that brought the feature of asynchronous candidate lists, so I change all the calls to Spotify to be non-blocking and used this new feature to fill up the possible tracks/albums/artists. From this commit on, the Spotify completion should feel snappier, so let me know if that solved the problem for you!
