Chunked/multipart upload presentation feedback

[orvn]

Recently, when uploading a file, the UI started giving less feedback on the percentage uploaded.

• In the case of small files, the upload appears to jump suddenly, from 0% to 100%
• When uploading a larger file, the user can see that pieces of it are being uploaded, but the progress feedback seems interspersed and sporadic

• On the new site design, this even looks like the upload might be hanging

• Note the progress feedback on last file (which is larger than the others)

• Implemented a stopgap

  • The ellipses are now animated on the new site design, providing visual feedback to the user that something is happening (they animate from one, to two, to three dots)
  • . → .. → ...

@dchoi27 I can solve this visually with some presentation layer delays and timeouts, but I'm not sure why this behavior appeared all of a sudden from the API/infra layers?

hm - so one thing that @alanshaw mentioned is that the progress just comes from the client's knowledge of how many chunks of the upload got uploaded. so it's not an API/infra thing, but just that the JS client after it's converted a file to a CAR and chunked it up into 100MB chunks knows how many of these chunks got uploaded. he also said that nothing's really changed to that end.

in the video you recorded with the new website, how large was the ezgif file?

The ezgif file is 270 KiB (it's actually the gif at the top of this issue), but the other file is a few hundred MiB.

Backburner sounds good. In the mean time we can figure out what a visual solution might look like.
