I'm not sure what's going on, but the API i set up on pythonanywhere is no longer returning requests. I was in the middle of testing it out from my local machine at home and all of a sudden it stopped replying.

The access logs go like this, you can see it was working and then all of a sudden, it wasnt.

any ideas?

I guess I'm asking why it's taking so long to get a response? I've tried leaving the request open for up to 100 seconds and still not getting any response. Any Thoughts?

How quickly does your api usually respond? (eg: if say it usually takes 5 seconds, and someone clicks on your endpoint 20 times, then no one else would be able to use your api for 100s)

It's usually basically instant. like if i only run it from local a few times in a row the api will respond before the 350 ms timeout function closes the process. (i added a timeout function recently bc the slow api response was causing the program to hang)

Put some logging into your app to see what it's doing when it's not responding. You may find there are specific arguments that cause it to get stuck or something like that.

Hi,

I put some logging in and i can see that code itself isnt getting hung up anywhere, its proceeding through the logic the way it should, but this error comes up, something about a pipe and a closed socket? Not sure how to rememdy this. Do you all do some type of throttling when a couple of requests come in in quick succession?

Those errors -- both the "499" in the access log and the SIGPIPE/GeneratorExit in the error log -- normally mean that a client (that is, someone calling your API) disconnects unexpectedly. Due to network conditions it's normal to see a few of those, but it's presumably not the case here.

I see the word "webscraper" in your code paths -- are your API calls accessing another external site? Maybe that could be rate-limiting you or something?

right, so its not the network conditions i dont think bc it only happens after a couple requests that work fine and get responded to. so i agree. the client closes connections if too much passes without a response from the server. i added that into my tests so the applciation doesnt hang.

i just named a directory with the word 'webscraper', there is no external accessing of sites going on here.

Also a heads up that I am on a free account tier. so I dont know if that affects whether you guys throttle the rate of the apps response to requests.

No, we don't throttle the number of requests/second. On a free account, your site has only one worker process handling all incoming requests. If it's processing one request, then any others that come in will be queued up until the process is free. But if it's normally instant, that seems like it's unlikely to be the cause.

What's it doing during the request processing?

dang, okay. so having a higher teir account would probably help at least somewhat by adding worker processes?

well its doing some os.walking to find a specific txt file and then reading the file and randomly chooosing a sequence of lines. maybe the opening file process is just slow? If i put the corresponding data into a real DB instead of a local directory of txt files do you think that would fix it?

Actually, that definitely will not fix it or thats not the bottleneck. according to the print statements in the server log, its actually getting the needed portion of texts totally fine. Its just the response is taking forever to get back to the client. I don't quite get it...

and my source code is here for reference: https://github.com/weAllWeGot/CardiB_api/blob/master/flask_app.py

additionally, here is a test locally that makes me think its not an issue with the speed of the code finishing as i run it many times in succession and the algorithm itself doesnt get hung up anywhere

So, just to make sure I understand -- when you run it on PythonAnywhere, are the results of the three prints at the end of your get method -- that is, the

print('lyric: ' + str(lyric))
print('song: ' + str(song))
print('artist: ' +str(artist))

...being printed to the error log? If so, do they have sensible timestamps -- say, within a second or two of the request coming in? (It might be worth adding another print at the start of get just to sanity-check that.)
