The goal of the issue wasn't to pass an upgrade-info location, but to get it from the cosmovisor node config. We have the root of the node, so we can know the path of the executable. Taking an argument doesn't close the issue.

Short: "Show upgrade-info.json into stdout.",

Let's not silence usage.
And let's add cobra.NoArgs

Args: cobra.ExactArgs(1),
RunE: showUpgradeInfoCmd,
}

return showUpgradeInfo
}

func showUpgradeInfoCmd(cmd *cobra.Command, args []string) error {
if len(args) != 1 {
return fmt.Errorf("expected exactly one argument")
}

data, err := os.ReadFile(args[0])
if err != nil {
return fmt.Errorf("failed to read upgrade-info.json: %w", err)
}

fmt.Println(string(data))

Let's use cmd.Println(string(data)) instead


return nil

🛠️ Refactor suggestion

Suggestions for improving error handling and output method.

The showUpgradeInfoCmd function is generally well-implemented, but there are a few areas for improvement:

  1. The argument check is redundant due to cobra.ExactArgs(1) in the command setup.
  2. Error handling could be more specific, especially for the "file not found" case.
  3. Directly printing to stdout might limit testability and reusability.

Consider applying these changes:

 func showUpgradeInfoCmd(cmd *cobra.Command, args []string) error {
-	if len(args) != 1 {
-		return fmt.Errorf("expected exactly one argument")
-	}
-
 	data, err := os.ReadFile(args[0])
 	if err != nil {
+		if os.IsNotExist(err) {
+			return fmt.Errorf("upgrade-info.json not found at %s: %w", args[0], err)
+		}
 		return fmt.Errorf("failed to read upgrade-info.json: %w", err)
 	}
 
-	fmt.Println(string(data))
+	_, err = fmt.Fprintln(cmd.OutOrStdout(), string(data))
+	if err != nil {
+		return fmt.Errorf("failed to write output: %w", err)
+	}
 
 	return nil
 }

These changes improve error specificity, remove redundant checks, and use cmd.OutOrStdout() for better testability.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The bot has great suggestion, could you implement them?

@julienrbrt, certainly! I've implemented the bot's suggestions.

Here's the updated show_upgrade.go file with the improvements applied:

package main

import (
	"fmt"
	"os"

	"github.com/spf13/cobra"
)

func NewShowUpgradeInfoCmd() *cobra.Command {
	showUpgradeInfo := &cobra.Command{
		Use:          "show-upgrade-info <path to executable>",
		Short:        "Show upgrade-info.json into stdout.",
		SilenceUsage: true,
		Args:         cobra.ExactArgs(1),
		RunE:         showUpgradeInfoCmd,
	}

	return showUpgradeInfo
}

func showUpgradeInfoCmd(cmd *cobra.Command, args []string) error {
	data, err := os.ReadFile(args[0])
	if err != nil {
		if os.IsNotExist(err) {
			return fmt.Errorf("upgrade-info.json not found at %s: %w", args[0], err)
		}
		return fmt.Errorf("failed to read upgrade-info.json: %w", err)
	}

	_, err = fmt.Fprintln(cmd.OutOrStdout(), string(data))
	if err != nil {
		return fmt.Errorf("failed to write output: %w", err)
	}

	return nil
}

These changes improve error specificity, remove the redundant argument check, and use cmd.OutOrStdout() for better testability, as suggested.
