echoer | custom process driven system custom business event | Application Framework library

right now I have a java program that uses threads and sockets to echo text responses like a real chat window. Currently, my program works by running the server and than as many clients as I want. When a client enters a message, that message is echoed to the server and also to the client that sent the message.

My problem is that I want the message any client enters to be sent not only to the server and to themselves, but to every other client as well.

Heres how it currently works:

Server:

Received client message: test1

Client 1:

Enter message: test1

test1

Client 2:

Enter message:

Client 1 enters test1, receives test1 back and the server also receives test1. Client 2 gets nothing. My goal is to have any messages entered in the clients display on the client that sent the message as well as the other clients and server.

Working example:

Server:

Received client message: test1

Received client message: hello

Client 1:

Enter message: test1

test1

From client 2: hello

Client 2:

Enter message:

From client 1: test1

hello

The formatting doesnt have to be exactly like that, but thats the idea. My code so far is below. Ive read that I need to add my clients to a list and then loop over them and send them all the message but im not sure. Any help would be great.

I want to send the stdout and stderr of terminal while I run a huge batch file. The batch file echoer.sh

I have written a TCP/UDP intercepting proxy using Twisted and I want to add some unit tests to it. I want to setup an echo protocol, then send some data through my proxy, then check the returned response.

However, it seems like even for a simple test using a socket (let aside my intercepting proxy) to connect to the echoer, the reactor desn't seem to be spawned after setUp - the test hangs forever. If I add a timeout to the socket then a timeout exception is raised. I even tried to connect with ncat to make sure is not the manually created socket to blame - the echoer is listening indeed but I receive no echoed data back to the ncat client.

The test code I use is the following

Suppose the following test-pipefail.sh batch:

My PHP code returns all of concatenated string except for the last string in the concatenation. How do I get the '");' to echo as well?

I am currently working on the Quarkus application. I have created an authentication service which will validate user and will create JWT token and send it to the client after successful authentications.

But currently, I am facing issue while creating a JWT token. For token creation, I am using

I made a Batch that fakes downloading files :

EDIT: The fix, as suggested by Harry Johnston, was to close the Child_In_Write handle.
Somewhat ironically, I had earlier tried closing the Child_In_Read handle. This does NOT work, the write handle is the only one that should be closed.

For the tool I'm trying to make, I need to be able to launch a process and give it data through stdin - as if I was calling it via command line with piping

Simple enough idea. I've primarily I've followed this guide from Microsoft and got things "working". In my own test program I can read from stdin just fine. But when I try to use other programs, like cat for instance, they do nothing but hang - as if they are still waiting for input.

Here are the relevant code bits:

Initialize the pipes.
