Try stracing your program to see exactly what it's doing with the socket, and try std.socket's lastSocketError I tried using ```lastSocketError()```, it gave an error saying *Connection reset by peer*. I'm confused about how the connection is getting reset. Figured it out! The error was on the python side as I was not receiving the data from d which was locally buffered.

Here's the complete code: https://github.com/utkarshb1/Interactive-Register-Debugging/blob/7919612396cf893bb5e9b936c2d8a44663ac6733/apb_slave/testbench/apb.d#L289 I'm receiving that error at line 362. The code should continuously wait for the data from python and once received it should do the computation defined in the code and then again wait for the data until EXIT signal is sent from python.

Not sure if you want build interprocess communication utility all by yourself, I'm currently using https://code.dlang.org/packages/apache-thrift and there is also https://code.dlang.org/packages/symmetry_thrift_d BTW grpc is not quiet working https://code.dlang.org/packages/grpc
How to recursively accept data from Python server ?
Hello!
I'm trying to establish a connection between a python server and
a d client. The data is been transferred properly only once and
then the d client doesn't wait for any further data and returns
an error ```Socket.ERROR``` and exists and doesn't wait for
further incoming data from the Python server. From Python, the
data is been sent whenever the user sends a request but instead
of waiting for incoming requests the D client just accepts the
data 1st time and then throws an error and exits.
The code snippet is as below:
```
bool get_req_from_socket(Socket socket) {
ubyte[] rawTrHeader;
ubyte[] buffer;
writeln("Waiting for data from socket");
while (rawTrHeader.length < 16) {
import std.string: format;
buffer.length = 16 - rawTrHeader.length;
auto ret = socket.receive(buffer);
uvm_info("SOCKET", format("Received %d bytes from socket",
ret),
UVM_DEBUG);
if (ret == Socket.ERROR)
uvm_fatal("SOCKET", "Error receiving data from socket");
if (ret == 0)
uvm_fatal("SOCKET", "Got insufficient bytes for TrHeader");
// now slice the buffer to get the part...
rawTrHeader ~= buffer[0 .. ret];
}
...
...
}
```
This is the function (infinitely called while it returns
```true```) that accepts the data and returns ```true``` or
```false``` depending on if data is received or not respectively.
The error I'm receiving is:
```
Waiting for data from socket
UVM_INFO ../testbench/apb.d(375) @ 13: reporter@@apb_seq
[SOCKET] Received -1 bytes from socket
UVM_FATAL ../testbench/apb.d(378) @ 13: reporter@@apb_seq
[SOCKET] Error receiving data from socket
```
Please help me to resolve this issue.
