If you’re facing issues with Delve (dlv) not restarting when updating files in your Go project using Cosmtrek/Air version 1.27.10 and encountering a “port address already in use” error, there are a couple of solutions you can try. This problem often occurs due to lingering Delve processes that prevent the tool from restarting properly.

Solution 1: Revert to a Previous Version

You can revert to a previous version of Cosmtrek/Air where this issue might not exist. To do this, follow these steps:

API testing is a crucial part of software quality assurance, ensuring that APIs function correctly, securely, and efficiently. This guide details key test actions, test scenario categories, and test flows to ensure a thorough validation of API behavior.

API Test Actions

Each API test involves several key actions:

In Bash scripting, it’s often useful to determine the directory where the script file is located. This can be particularly important if your script needs to access other files or resources relative to its own location. Here’s a Bash script snippet that accomplishes this task:

#!/bin/bash

# Get the directory of the script file
SCRIPT_DIR=$(cd -- "$(dirname -- "${BASH_SOURCE[0]}")" &> /dev/null && pwd)

# Check if SCRIPT_DIR is empty or not
if [ -z "$SCRIPT_DIR" ]; then
  echo "Failed to determine the script directory."
  exit 1
fi

# Now, you can use SCRIPT_DIR for your operations
echo "The script is located in the directory: $SCRIPT_DIR"

Microservices

Better suited to a project team or department where multiple products exist and are made up of sub-components.

Your provided code snippet appears to be a Bash script that checks if the TARGET_PATH environment variable is empty and, if so, sets it to ~/go by appending an export statement to the .bashrc file. This is a common technique to ensure that environment variables are set with default values if they are not already defined.

Here’s a breakdown of what the code does:

1. if [[ -z "${TARGET_PATH}" ]]; then: This line checks if the TARGET_PATH environment variable is empty (i.e., its value is not set). The -z flag is used to test if a string is empty.

It looks like you are trying to check if a specific directory is included in the PATH environment variable in a Bash script. The code you provided is almost correct, but it has a small issue. You can modify it as follows to make it work correctly:

CHECK_PATH="/root/go/bin"

if [[ ":$PATH:" == *":$CHECK_PATH:"* ]]; then
    echo "Path found in PATH environment. Skipping configuration..."
else
    echo "Path not found in PATH environment. You may need to add it."
fi
