Unable to read a url using fsspec https filesystem implementation directly - python-3.x

I am using fsspec package to implement a function to read an https file.
_hostname = socket.gethostname()
proxy_auth = aiohttp.BasicAuth(_hostname, pwd)
of = fsspec.filesystem("https", client_kwargs={"trust_env":True, "auth":proxy_auth})
http_urls = ["https://stackoverflow.com/"]
print(of.cat(http_urls))
The above code is not fetching the content of the url. The stack trace for the above code is as follows:

But if we wrap it with a cache, I am able to get the content.
_hostname = socket.gethostname()
proxy_auth = aiohttp.BasicAuth(_hostname, pwd)
of = fsspec.filesystem("simplecache", target_protocol="https", \
target_options={"client_kwargs":{"trust_env":True, "auth":proxy_auth}},
cache_storage="/tmp/files")
http_urls = ["https://stackoverflow.com/"]
print(of.cat(http_urls))
Why is the first code section not able to fetch the content? Am I doing anything wrong ?

AttributeError at /logout/ 'tuple' object has no attribute 'backend'

I used Python3 in windows 10 to write a django2 web app.
I tried to configure the LDAP login, but failed.
When I test using postman, it could get the reply successfully.
That is, I send a request to https://example.com/staff, with some authentication code and payload containing username and password, and it reply me with the LDAP reply.
However, when I tried to using ldap3 in Django, after successfully login, error shows:

You write the following line:
user = UserModel.objects.update_or_create(username=username)
The update_or_create method returns a tuple with the object and a boolean with whether the object was created. So you are storing this tuple in the variable user and returning that. But authenticate is supposed to return only the user causing unintended effects leading to an error. Also you should be using get_or_create [Django docs] instead of update_or_create.
So you should change that above line to:
user, created = UserModel.objects.get_or_create(username=username)

Pickling Python Function fails with ProcessPoolExecutor in a decorator

So I asked this question and tried the ProcessPoolExecutor approach. I used the decorator suggested the following way:
Running Image Manipulation in run_in_executor. Adapting to multiprocessing
import asyncio
import functools
from concurrent import futures
from app.exceptions.errors import ManipulationError
_pool = futures.ProcessPoolExecutor()
def executor(function):
#functools.wraps(function)
def decorator(*args, **kwargs):
try:
partial = functools.partial(function, *args, **kwargs)
loop = asyncio.get_event_loop()
return loop.run_in_executor(_pool, partial)
except Exception as e:
raise ManipulationError(str(e))
return decorator
I then used it on a function like:
#executor
#pil
def blur(image):
frame = image.convert("RGBA")
return frame.filter(ImageFilter.BLUR)
Note the #pil is another decorator I made.
def pil(function):
#functools.wraps(function)
def wrapper(image, *args, **kwargs) -> BytesIO:
img = PILManip.pil_image(image)
if img.format == "GIF":
frames = []
for frame in ImageSequence.Iterator(img):
res_frame = function(frame, *args, **kwargs)
frames.append(res_frame)
return PILManip.pil_gif_save(frames), "gif"
elif img.format in ["PNG", "JPEG"]:
img = function(img, *args, **kwargs)
return PILManip.pil_image_save(img), "png"
else:
raise BadImage("Bad Format")
return wrapper
I called it in a FastApi route like so:
#router.get("/blur/", responses=normal_response)
async def blur_image(url: str):
byt = await Client.image_bytes(url)
img, image_format = await blur(byt)
return Response(img.read(), media_type=f"image/{image_format}")
I get some error about pickling.

_pickle.PicklingError: Can't pickle <function blur at 0x7f87524091f0>: it's not the same object as app.image.pil_manipulation.blur
Does someone know why this keeps happening?
I was told the objects have to be serializable, I believe BytesIO is the only in/out of the image. That should be serializable.
Decorators typically produce wrapped functions that aren't easy to pickle (serialize) because they contain hidden state. When dealing with multiprocessing, you should avoid decorators and send ordinary global functions to run_in_executor. For example, you could re-write your executor decorator into a utility function:
_pool = concurrent.futures.ProcessPoolExecutor()
async def exec_async(fn, *args):
loop = asyncio.get_event_loop()
return await loop.run_in_executor(_pool, fn, *args)
Instead of decorating a function with executor, you can just await it using await exec_async(some_function, arg1, arg2, ...). Likewise, you can rewrite the pil decorator into another utility:
def pil(image, transform):
img = PILManip.pil_image(image)
if img.format == "GIF":
frames = []
for frame in ImageSequence.Iterator(img):
res_frame = transform(frame)
frames.append(res_frame)
return PILManip.pil_gif_save(frames), "gif"
elif img.format in ["PNG", "JPEG"]:
img = transform(img)
return PILManip.pil_image_save(img), "png"
else:
raise BadImage("Bad Format")
The implementation of blur now becomes an ordinary function which calls pil, and which can be safely passed to exec_async:
def blur(image):
def transform(frame):
frame = frame.convert("RGBA")
return frame.filter(ImageFilter.BLUR)
return pil(image, transform)
#router.get("/blur/", responses=normal_response)
async def blur_image(url: str):
byt = await Client.image_bytes(url)
img, image_format = await exec_async(blur, byt)
return Response(img.read(), media_type=f"image/{image_format}")
Note: the above code is untested.

Take a System Reboot.
While you initiate PhantomJS() provide the absolute path of the phantomjs binary as follows :
driver = webdriver.PhantomJS(executable_path=r'C:\path\to\phantomjs.exe')
Ensure that there is no unnecessary imports in your script. Example : urllib.request
Execute your Test.

Proxybroker - AttributeError 'dict' object has no attribute 'expired'

Well I have this weird problem. Same script works on windows7 and on windows10 throws AttributeError. And I just can't figure out what is the difference.
This is py code:
import asyncio
from proxybroker import Broker
async def use(proxies):
while True:
proxy = await proxies.get()
if proxy is None:
break
elif 'SOCKS5' in proxy.types: # filter by type
print('Found SOCKS5 proxy: %s' % proxy)
else:
print('Found proxy: %s' % proxy)
async def find(proxies, loop):
broker = Broker(queue=proxies,

max_concurrent_conn=200,
judges=['https://httpheader.net/', 'http://httpheader.net/'],
providers=['http://www.proxylists.net/', 'http://fineproxy.org/eng/'],
verify_ssl=False,
loop=loop)
# only anonymous & high levels of anonymity for http protocol and high for others:

await broker.find(types=types, countries=countries, limit=limit)
