QUESTION
Suppose I want to model, using Haskell pipes, a Python
Generator[int, None, None]
which keeps some internal state. Should I be usingProducer int (State s) ()
orStateT s (Producer int m) ()
, wherem
is whatever type of effect I eventually want from the consumer?How should I think about the notion of transducers in pipes? So in Oleg's simple generators, there is

ANSWER
Answered 2022-Mar-31 at 18:32In pipes
, you typically wouldn't use effects in the base monad m
of your overall Effect
to model the internal state of a Producer
. If you really wanted to use State
for this purpose, it would be an internal implementation detail of the Producer
in question (discharged by a runStateP
or evalStateP
inside the Producer
, as explained below), and the State
would not appear in the Producer
's type.
It's also important to emphasize that a Producer
, even when it's operating in the Identity
base monad without any "effects" at its disposal, isn't some sort of pure function that would keep producing the same value over and over without monadic help. A Producer
is basically a stream, and it can maintain state using the usual functional mechanisms (e.g., recursion, for one). So, you definitely don't need a State
for a Producer
to be stateful.
The upshot is that the usual model of a Python Generator[int, None, None]
in Pipes
is just a Monad m => Producer Int m ()
polymorphic in an unspecified base monad m
. Only if the Producer
needs some external effects (e.g., IO
to access the filesystem) would you require more of m
(e.g., a MonadIO m
constraint or something).
To give you a concrete example, a Producer
that generates pseudorandom numbers obviously has "state", but a typical implementation would be a "pure" Producer
:
QUESTION
I'm working with FTPClient against an FTP server using Testcontainers
.
A reproducible code sample is here:
...ANSWER
Answered 2021-Dec-16 at 00:06As you already figured out in the comments, the tricky part about FTP passive mode is that the server uses another port (not 21) for communication.
In the docker image you're using, it's a port from the 21000-21010
range by default. So you need to publish (expose) these additional container ports. In docker run
command you used -p 21000-21010:21000-21010
for that.
However, Testcontainers library is designed to publish to random host ports to avoid the problem, when a desired fixed port (or a range of ports) is already occupied on the host side.
In case of FTP passive mode random ports on the host side cause problems, because afaik you can't instruct the ftp client to override the port, which FTP server returned for the passive mode. You'd need something like ftpClient.connect("localhost", ftp.getMappedPort(PORT));
but for passive mode ports as well.
Therefore the only solution I see here is to use a FixedHostPortContainer. Even though it's marked as deprecated and not recommended to use because of the mentioned issues with occupied ports, I think this is a valid use case for it here. FixedHostPortGenericContainer
allows to publish fixed ports on the host side. Something like:

Trying to install Python 3.10.0 on MacOS 11.6 (Intel) with pyenv 2.1.0 (from homebrew) fails with:
...ANSWER
Answered 2021-Oct-06 at 05:56Try env ARCHFLAGS="-arch x86_64"
(that works for me for other Python-related tools, I don't use pyenv myself).
Rationale: modern macOS supports 2 architectures: intel (x86_64) and m1 (arm-something). Compiling for only one architecture is easier.

QUESTION
So I have this file that I download via ftp. The file is just a config file for a system at my company I work for.
Once the file is downloaded I open the file and processor the file.
Part of the processing of the file is to check to see if a line starts with a Unicode character \u001a
.
This is where I am stumped because .StartsWith("\u001a")
is always true
, yet I cannot see why. If I view the file in Notepad++ or in a hex editor, I just don't see that.
So there is something I am missing here.

It seems the stable

tags are currently a bit broken at docker hub.
For Debian 10 and older, the repo uses the subdirectory structure {RELEASE}/updates
to contain the security updates;
