I have a python script in a docker that runs and collects data from an api on a loop.
`for idx, items in enumerate(SearchList):
#get access token
access_token = GetPricingAccTok()
#request id to get results
reqid = RequestIdCompSearch(items, access_token)
#api to get results by doing a while loop appending results together till api returns 100% as completed percentage
Result = GetReqResults(reqid, access_token)
Pricings = GetPricingDict(Result)
filenamepricing = "pricinghistory/CorrectFormat/Pricings_Data_{idn}_{ts}.json".format(
idn = idx,
ts= dt.datetime.now().isoformat()
)
GetAzContainer().upload_blob(
name=filenamepricing,
data=json.dumps(obj= Pricings, indent=4),
blob_type='BlockBlob'
)
`
When i run and test this code locally on my windows machine it works well without an issue and completes the requests
but in the docker on azure container instance it then returns an error showing that the connection has timed out. Not sure what the difference is between the running it locally and in the docker that i then recieve this error.
I have tried addinng this code at the start
import socket
from urllib3.connection import HTTPConnection
HTTPConnection.default_socket_options =(HTTPConnection.default_socket_options + [
(socket.SOL_SOCKET, socket.SO_KEEPALIVE, 1) #Enables the feature
,(socket.SOL_TCP, socket.TCP_KEEPIDLE, 45) #Overrides the time when the stack willl start sending KeppAlives after no data received on a Persistent Connection
,(socket.SOL_TCP, socket.TCP_KEEPINTVL, 10) #Defines how often thoe KA will be sent between them
,(socket.SOL_TCP, socket.TCP_KEEPCNT, 60) #How many attemps will your code try if the server goes down before droping the connection.
]
)
but it still times out. showing the below error

I have two telegram bots made with PyTelegramBotApi (not the best library, I know) deployed on Heroku. One big difference that matters: one is running with Threading to periodically send notifications to "subscribers" (around 20 people). And it crashes approximately every month with following exception trace in Heroku console:
2022-01-14T08:00:11.068553+00:00 app[worker.1]: File "/app/.heroku/python/lib/python3.9/site-packages/telebot/apihelper.py", line 139, in _make_request

I didn't record previous exception traces (my bad), but I can remember it looking pretty much the same (with the most recent exception being ReadTimeout). Moreover, any of my scripts were never seen in this trace (and this makes me feel it's incomplete due to some Heroku log console bug). I myself don't use requests module directly. Also it definitely can't be caused by dyno sleep as I use only worker dyno (it never sleeps). Both this bot and the one not crashing are using Heroku Postgres.
Any ideas on what could be causing this exception?
EDIT:
full exception trace I accidentally got in debug mode while testing somethin else on my machine:

I have found a way to at least keep the bot working. Be careful: this may not fit your application (in your case restarting straight up after a specific exception may corrupt data or break something else). In main file, I made this construction, which basically restarts a bot after an unhandled exception, which would otherwise just stop the bot:
def exception_handler(count: int = 0):
"""Relaunching bot unless exceptions occur more than 2 times a day
(script is reset daily on Heroku)"""
if count < 3:
if count > 0:
print("An exception occurred, relaunching . . .")
time.sleep(5)
try:
deadliner0307() # bot main function with (bot.polling starts there)
except Exception as ex:
count += 1
# Notifying myself about exception via free Airbrake addon:
notifier = pybrake.Notifier(project_id=399289,
project_key='129d3450356965175fda762b69e1babf',
environment='production')
notifier.notify(ex)
exception_handler(count)
else:
print("Too much exceptions occurred, shutting down . . .")

I have a kubernetes cluster (on GKE) which runs tornado.web.Application server, that calls heavy dask.distributed calculations on that cluster.
Now I want to test my server, and send it multiple requests at once, to see if it handles those requests as it should.
When I'm sending only one request, it does everything and behaves as expected, no matter how big the request is.
But when I send more than one request, after like 5 minutes (I also tried on server side just to sleep, without making any calculations and got the same results), I get the following:

How can I get the behaviour I need, without these errors?
I need a server that can handle many requests, and to test it from my computer.
I am trying to launch my script to PA and while it works locally it does not work on PA and I cannot figure out why. I have the paid version of PA so I can access this site that is not whitelisted. Here is my script:
with requests.Session() as session:
# initates the login session
if os.path.exists(document_report + '.pdf'):
# initates the login session
post = session.post(POST_LOGIN_URL, data=payload, headers = dict(referrer = 'https://www.example.com/loginpage'))
#This URL is the page you actually want to pull down with requests.
REQUEST_URL = f'https://www.example.com/{stuff}/{document}'
#gets the request URL
r = session.get(REQUEST_URL)
# saves to directory
with open('./digests/1.pdf', 'wb') as j:
j.write(r.content)
j.close()
else:
post = session.post(POST_LOGIN_URL, data=payload, headers = dict(referrer = 'https://www.example.com/loginpage'))
#This URL is the page you actually want to pull down with requests.
REQUEST_URL = f'https://www.example.com/{stuff}/{document}'
#gets the request URL
r = session.get(REQUEST_URL)
# saves to directory
with open(document_report + '.pdf', 'wb') as j:
j.write(r.content)
j.close()
When I run the code, I get the following message:

I tried it again locally, and it still works. Any insight into a solution would be amazing!
I'm fetching OHLCV data from Binance via Binance api on AWS-EC2.
But sometime(once a couple of days) error "104, 'ECONNRESET'" occur and program stop.
The program written in Python3.7.3 and run on AWS-EC2
The code is following. But this code couldn't continue.
I want to continue the program running when any api or connection error occured.
How should I handle this error ?
while True:
..............
try :
klines = client.get_historical_klines(ticker_symbol, Client.KLINE_INTERVAL_1MINUTE, _from_str, _until_str)
except BinanceAPIException as e:
print(e)
print('Something went wrong. Error occured at %s. Wait for 1 hour.' % (datetime.datetime.now().astimezone(timezone('UTC'))))
sleep(3600)
continue
..............
All error massege are following.

Assuming that you are using python-binance module, most likely the error happens because you are trying to reuse the client after long time (server timeout). You can try to recreate the client first:
...
client = Client(api_key, api_secret)
while True:
...
try :
klines = client.get_historical_klines(ticker_symbol, Client.KLINE_INTERVAL_1MINUTE, _from_str, _until_str)
except BinanceAPIException as e:
print(e)
print('Something went wrong. Error occured at %s. Wait for 1 hour.' % (datetime.datetime.now().astimezone(timezone('UTC'))))
sleep(3600)
client = Client(api_key, api_secret)
continue
...
The reason is because the [Client][2] uses requests Session underneath which imply usage of urllib3's connection pooling. This connection pooling can not be reused after timeout.
I'm having this nasty error:

According to this answer the solution for my issue is to place :
time.sleep(0.01) strategically in my code. I get the idea of it but I'm not sure I know where the correct spot for it in my code:
This is the relevant code part from script.py :
result= []
with ThreadPoolExecutor(max_workers=num_of_pages) as executor:
futh = [(executor.submit(self.getdata3, page, hed, data, apifolder,additional)) for page in pages]
for data in as_completed(futh):
result.extend(data.result())
print ("Finished generateing data.")
return result
This is the relevant code part from getdata3 function :
def getdata3(...)
datarALL = []
responsedata = requests.get(url, data=data, headers=hed, verify=False)
if responsedata.status_code == 200: # 200 for successful call
responsedata = responsedata.text
jsondata = json.loads(responsedata)
if "results" in jsondata:
if jsondata["results"]:
datarALL.extend(jsondata["results"])
print ("{1} page {0} finished".format(page,str(datetime.now())))
return datarALL
Some info:
My code generates pages.
Create thread per page executing getdata3 (which makes GET request to API)
each thread return the result of a single page.
"merging" results.
My question:
Where to put the time.sleep(0.01) in order to avoid this error?
you might already figured this out. Any way, I had a similar problem while making post requests in a for loop, which run 400 times, each loop run with two requests and a last request after exiting the loop. I found out while making API requests the server (check_mk) was not ready, still compiling some hots and service data. So I placed the time.sleep() just before the each request and that fixed the problem. I don't know how often you make the requests but I'd try it this way:
def getdata3(...)
datarALL = []
time.sleep(0.01)
responsedata = requests.get(url, data=data, headers=hed, verify=False)
if responsedata.status_code == 200: # 200 for successful call
responsedata = responsedata.text
jsondata = json.loads(responsedata)
if "results" in jsondata:
if jsondata["results"]:
datarALL.extend(jsondata["results"])
print ("{1} page {0} finished".format(page,str(datetime.now())))
return datarALL
As suggested in this thread by the same user posting the problem, it might be due to your internet connection. I had the same problem and changed my internet connection to another network and the issue was solved for me. Then you can give it a try changing your internet network.
