I've written a logging.filter and would like to use doctest on it
(using a StreamHandler for stdout), but this doesn't seem possible.
Output from the logger seems to disappear (running the doctest strings
through the interpreter as-is yields expected results). I assume this
is because doctest does something with logging. Is there any way to
make these work together?

It redirects stdout to a StringIO subclass to capture the output.

Using the StreamHandler with something like
class WrapStdOut(obje ct):
def __getattr__(sel f, name):
return getattr(sys.std out, name)
instead of sys.stdout directly should work.

Using the StreamHandler with something like

def __getattr__(sel f, name):
return getattr(sys.std out, name)
instead of sys.stdout directly should work.
Or create the StreamHandler inside your doctest where sys.stdout is already
redirected.

I was creating the StreamHandler inside doctest. Turns out, however,
that I hadn't imported 'sys', and so it didn't work. Its a little
strange that this didn't result in an error, but there you have it.
Thanks for the tip that led me to discover this.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
