Hanging the whole instance while running the script in the usage section

[luk0y]

What happened?

I am trying to run the example code but have had no luck. It always keeps hanging the AWS instance

Version and System configurations

Go Version: go version go1.19 linux/amd64
System Configurations : AWS Instance 2 GB RAM, 1 vCPU, 60 GB SSD
Operating System: Ubuntu 20.04

Steps to reproduce

1. Installing the 1.19 version of go through go.dev. followed the installation procedure till setting the paths in .profile

2. Saved the code from the Usage section https://github.com/gotd/td#usage by naming it as hello.go

package main

import (
	"context"

	"github.com/gotd/td/telegram"
)

func main() {
	// https://core.telegram.org/api/obtaining_api_id
	client := telegram.NewClient(appID, appHash, telegram.Options{})
	if err := client.Run(context.Background(), func(ctx context.Context) error {
		// It is only valid to use client while this function is not returned
		// and ctx is not cancelled.
		api := client.API()

		// Now you can invoke MTProto RPC requests by calling the API.
		// ...

		// Return to close client connection and free up resources.
		return nil
	}); err != nil {
		panic(err)
	}
	// Client is closed.
}

3. Assigned values to variables appID(Int), appHash(String) in the file hello.go

4. go mod init hello.go

5. go mod tidy

6. Ran the code hello.go using go run hello.go and I can't see anything on the screen. It just hangs

When I ran the code in tmux and tried checking from outside of tmux to know if the hang is because of too much usage of CPU/memory using the command top. It's shown that the command "compile" is taking too much CPU power and memory

If I keep running it like this for 5-10 mins, I can't be able to access my instance again. Tried the same procedure in multiple instances but the issue was not resolved

Can you try to compile the source first? Use go build to compile it to a binary file then execute.

@giautm It's still the same. My instance got stuck again due to the high usage of CPU

[giautm]

Can you try compile the source in your local machine and upload the binary to your server?

[giautm]

You need to add some compile flag to ensure Golang build correct Arch for linux, please Google it

[luk0y]

Thank you so much. The executable is working fine on the server, but I don't understand the issue while compiling the same on the server.

The AWS instance may take long time to compile your source, it doesn't have enought performance to do that.
