exchangelib not work with some subject filters

I am having the following problem to get the unread emails.
When the subject is "REALIZADAS" it works fine and brings me the emails quickly, but when the subject is "G.09.xlsx" it takes a long time and fails to deliver this error
'An existing connection was forced to break by the remote host', None, 10054, None) ", ConnectionResetError (10054, 'An existing connection was forced to break by the remote host'
This is the untranslated error
During handling of the above exception, another exception occurred:

This is the code
id_ = []
mails_filters = a.inbox.filter(subject=filter_)
for m in mails_filters:
if not m.is_read:
id_.append(m.id)
I tried with
.filter (subject__contains = filter_)
.filter (Q ("subject:" + filter_))
and it only worked for me when the filter was .filter (subject__contains = "09"), if I use "G" or "xlsx" it doesn't work.
I do not know what it could be. Maybe it's the time it takes to search? Can I modify that time so that it waits longer without getting the error?

catching "socket.timeout The read operation timed out" in python

I'm making calls to an API and am receiving the following timeout error:
socket.timeout The read operation timed out
which traces back from
File "/Users/someuser/anaconda/envs/python3/lib/python3.5/http/client.py", line 1198, in getresponse

File "/Users/someuser/anaconda/envs/python3/lib/python3.5/ssl.py", line 583, in read
v = self._sslobj.read(len, buffer)
socket.timeout The read operation timed out
How can I catch this error from the top of the traceback?

This is a duplicate question, however the correct approach is to catch socket.timeout by using
import socket
try:
...
except socket.timeout:
...
The error states the exception that was thrown explicitly and you can rely on that. Even though the calling method is the ssl lib, the error seems to be related to the actual socket connection.

Google search led to me https://community.home-assistant.io/t/difficulty-catching-an-exception/12955/6
It seems like SSL throws ssl.SSLError when it times out. You could try something like:
import ssl
def getresponse():
...
try:
response.begin
except ssl.SSLError as err:
handle_error(err)

Django Closed Socket Error with Repeated AJAX Calls [WinError 10053] An established connection was aborted by the software in your host machine

I'm trying to implement a live search through the jquery plugin Select2 in my Django 1.11.4 project. Running Python 3.6. When I type in the textbox, the server doesn't seem to be able to handle the number of requests and it closes, followed by these series of errors.
I've spent a couple hours following a couple threads on SO SO(more) , Google, etc but none have a working solution. I thought it was a python version issue, but I've upgraded from 2.7 to 3.6 and still have it. Any help would be great thanks!
This the view that's being called by the ajax call:
def directory_search(request):
# Query text from search bar
query = request.GET.get('q', None)
if query:
# Searches the DB for matching value
customers = Customer.objects.filter(
Q(name__icontains= query)|
Q(contract_account__icontains= query)|
Q(address__icontains= query)|
Q(address__icontains= query)|
Q(email__icontains= query)
).distinct()
# Turns queryset into dict
customers = customers.values("contract_account","name")
# Turns dict into list
customers_list = list(customers)
return JsonResponse(customers_list, safe=False)
else:
return JsonResponse(data={'success': False,'errors': 'No mathing items found'})
This is the js/ajax call for the Select2 plugin:
$(".customer-search-bar").select2({
ajax:{
dataType: 'json',
type: 'GET',
url:"{% url 'portal:directory_search' %}",
data: function (params) {
var queryParameters = {
q: params.term
}
return queryParameters;
},
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.contract_account
}
})
};
}
},
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 1,
templateResult: formatRepo,
templateSelection: formatRepoSelection,
language: { errorLoading:function(){ return "Searching..." }}
});

It appears that its a python 2.7 known bug, maybe it remains on python 3.6:

Edit
It seems to be a error on chrome. It didn't come to me, 'cause I was using Opera, but opera uses chromium as well. In internet explorer the error didn't show.

Python: Why do is the traceback getting printed?

I have a function. The function get started in some more threads. I tried to print a own error message. But its not important what I do I get still the traceback printed. My function:
def getSuggestengineResultForThree(suggestengine, seed, dynamoDBLocation):
results[seed][suggestengine] = getsuggestsforsearchengine(seed, suggestengine)
for keyword_result in results[seed][suggestengine]:
o = 0
while True:
try:
allKeywords.put_item(
Item={
'keyword': keyword_result
}
)
break
except ProvisionedThroughputExceededException as pe:
if (o > 9):
addtoerrortable(keyword_result)
print('ProvisionedThroughputExceededException 10 times in getSuggestengineResultForThree for allKeywords')
break
sleep(1)
o = o + 1
print("ProvisionedThroughputExceededException in getSugestengineResult")
But I get for every Thread an output like this:
Exception in thread Thread-562:

botocore.exceptions.ClientError: An error occurred (ProvisionedThroughputExceededException) when calling the PutItem operation: The level of configured provisioned throughput for the table was exceeded. Consider increasing your provisioning level with the UpdateTable API
Can someone help me to get my own print instead of the traceback? :)

This answer is a bit late for your question but here it is in case anyone is searching for this answer.
The exception that boto3 throws is a botocore.exceptions.ClientError as Neil has answered. However you should check response error code for 'ProvisionedThroughputExceededException' because the ClientError could be for another issue.
from botocore.exceptions import ClientError
except ClientError as e:
if e.response['Error']['Code'] != 'ProvisionedThroughputExceededException':
raise
# do something else with 'e'
I am using Python 2.7 which may or may not make a difference. The exception that I receive suggests that boto3 is already doing retries (up to 9 times) which is different from your exception:
An error occurred (ProvisionedThroughputExceededException) when calling the PutItem operation (reached max retries: 9): The level of configured provisioned throughput for the table was exceeded. Consider increasing your provisioning level with the UpdateTable API.

It's possible that ProvisionedThroughputExceededException is not actually the error. Try:
except botocore.exceptions.ClientError as pe:
instead.
If that doesn't work, figure out what line the error is occurring on and put the except statement there.

ConnectionResetError: [Errno 54] Connection reset by peer
According to the errno library Errno 54 is errno.EXFULL which in the python 3 documentation is explained as exchange full.
To my understanding the Connection reset by peer is Errno 104 i.e errno.ECONNRESET.
So what does errno.EXFULL mean? and why does socket raise the error with a connection reset by peer description instead of exchange full. And or how are the two errors errno.EXFULL and errno.ECONNRESET related?
PS: I read that the errno 54 might be related to http proxy (I'm using a proxy in my code). If so, how?

According to the errno library Errno 54 is errno.EXFULL
Did you determine that by examining errno.errorcode[54]? Anyway - this errno library might be at fault. You could verify the meaning of an error code on your system by looking into errno.h, e. g. with the help of gcc:
gcc -xc -imacros errno.h -Wp,-P -E <(echo ECONNRESET)
Also, the Python documentation says:
To translate a numeric error code to an error message, use
os.strerror().
It may well be that error number 54 is ECONNRESET on your system, and that os.strerror(54) will attest that.
Now that you have verified that os.strerror(54) returns 'Exchange full', I am puzzled why the error number 54 and the error string Connection reset by peer do not match. If that happens on a system with strace or something similar, I would further check which error is returned by the operating system through use of strace -e network on the affected process.
Regarding your question about EXFULL: Its meaning seems somewhat system dependent; e. g. on Linux, EXFULL is returned from only a handful places in the kernel, the only network-related place being in br_if.c concerning network bridges, when no available bridge port number is found (other places are in USB and SCSI drivers).

You can try this code to your project:

ssl._create_default_https_context = ssl._create_unverified_context
if it not work,make sure the server open TLSv1 support.
