the fly app fails on semantic search

@LuchoTurtle

You can record and listen to your audio but then the app fails.

What do you see in the logs?

[LuchoTurtle]

🤔 Interesting.

The logs say:

** (File.CopyError) could not copy from "/tmp/plug-1712-Rp-C/live_view_upload-1712263920-187903422807-3" to "/app/priv/static/uploads/tmp.wav34a10671-5ec5-49c1-84b6-3439a10e044f.wav": no such file or directory

However, when running on localhost, it seems to be working.

I don't know if this may be related with the on-going DDOS attack on fly.io right now.

[LuchoTurtle]

@nelsonic while on the topic, I think we should turn off the machine indefinitely. There's a higher volume of requests and having it running (even with the volume not redownloading optimization) is costing a fair amount of money. People can run it on localhost for themselves.

[ndrean]

I was also really wondering about the costs of running models on GPUs......Good to know

Some thoughts about the error:

"/app/priv/static/uploads/tmp.wav34a10671-5ec5-49c1-84b6-3439a10e044f.wav": no such file or directory

1. The failing line is 217 in "page_live.ex":
   https://github.com/ndrean/image-classifier/blob/00a5b6183bb7ab6ee888d2b80d6750a954065e41/lib/app_web/live/page_live.ex#L218

Maybe the format "tmp.wavuuid.wav" gives some trouble to the underlying OS????

This is because I set:

#page_live.ex
@tmp_wav Path.expand("priv/static/uploads/tmp.wav").....line 24
# set it in this assigns line 48
# use it line 217
tmp_wav = assigns.tmp_wav <> Ecto.UUID.generate() <> ".wav"
:ok = File.cp!(path, tmp_wav)

Maybe you can try with:

- @tmp_wav Path.expand("priv/static/uploads/tmp.wav").....line 24
+ @tmp_wav Path.expand("priv/static/uploads/tmp").....line 24

2. no directory:
   There is a check_or_create line :ok = File.mkdir_p!(@upload_dir) in the GenServer App.KnnIndex at line 23. This Genserver is started conditionnally by default in "Application.ex" so I guess this is not the reason.

@ndrean if you're curious how much it costs, see the invoice: #98 💸

[LuchoTurtle]

@ndrean shouldn't be OS-related at all since it has been working for the past two weeks just fine 🤔 . It's hard to not associate it with the DDOS attack that happened yesterday. Further latency probably made it so the audio file was not properly created

[ndrean]

@LuchoTurtle
I just tested it live yesterday, so I thought the mistake (?) was mine. So good to know it worked.

[ndrean]

So we should close this one!
