host.Users() returns nil on macOS #1510

ChrisSwanson · 2023-08-20T18:33:55Z

Describe the bug
While attempting to retrieve users on macOS, it appears as though the API in macOS previously used has been deprecated. I encountered this issue while recently attempting to run the Users function in the host package (on macOS 13.5).
When I run the function, the following error is provided:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/IOKit.framework/Headers/IOKitLib.h:133:19: note: 'kIOMasterPortDefault' has been explicitly marked deprecated here

To Reproduce

package main

import (
	"fmt"
	"github.com/shirou/gopsutil/host"
)

func main() {
	users, err := host.Users()
	if err != nil {
		panic(err)
	}
	fmt.Printf("%#v\n", users)
}

Expected behavior
It looks like the macOS API has deprecated the previously used call, and should be upgraded to the new endpoint is a rename from Master to Main, kIOMainPortDefault.

Environment (please complete the following information):

Windows: [paste the result of ver]
Linux: [paste contents of /etc/os-release and the result of uname -a]

perhaps duplicate of #1164.

ChrisSwanson · 2023-09-03T01:42:56Z

On the surface this appears that it may be a duplicate, but the previous issue was closed as deprecation warnings were previously resolved. I have been running this with the latest version of gopsutil to find that these warnings have resurfaced and are causing issues not just with deprecation warnings, but additionally causing values to be returned nil when they previously had been populating as a result. Since this is no longer just depercation warnings, I believe to be a new issue.

Lomanic · 2023-09-03T19:42:49Z

You are not using the latest version of gopsutil as you still import "github.com/shirou/gopsutil/host" (v2) instead of "github.com/shirou/gopsutil/v3/host from your example.

This really is a duplicate #1164. Update gopsutil to its v3.

ChrisSwanson · 2023-09-03T19:56:52Z

Ack, apologies, you are correct: the error (deprecated value returned by macOS) was stemming from the aforementioned missed v3 update in the import. However, it looks like on the updated version of the package, a nil response is still provided regardless of version. I can recreate in a new issue to deconflate these issues if you would like

running the initially provided example code:

$ go run main.go
# github.com/shirou/gopsutil/host
smc_darwin.c:75:41: warning: 'kIOMasterPortDefault' is deprecated: first deprecated in macOS 12.0 [-Wdeprecated-declarations]
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/IOKit.framework/Headers/IOKitLib.h:133:19: note: 'kIOMasterPortDefault' has been explicitly marked deprecated here
[]host.UserStat(nil)

running the aforementioned code with the updated import:

$ go run main.go
[]host.UserStat(nil)

host.Users() gets its data from /var/run/utmpx on darwin, can you please share this file with us?

Thanks for sharing this data, I could test (on linux) by copying a bunch of definitions to read this example utmpx file. And parsing this file works with the amd64-specific struct definitions, but not with the arm64-specific ones.

Can you confirm by testing after copying host/host_darwin_amd64.go over host/host_darwin_arm64.go? If you run mktypes.sh on the arm64 host, does it generate a different host/host_darwin_arm64.go from what's in gopsutil master?

shirou · 2023-09-30T03:31:59Z

Please change your code like this.

 import (
        "fmt"
-       "github.com/shirou/gopsutil/host"
+       "github.com/shirou/gopsutil/v3/host"
 )

Without specifing version, your code uses github.com/shirou/gopsutil v3.21.11+incompatible which is not latest. You can check on go.mod. With version, github.com/shirou/gopsutil/v3 v3.23.8 will be used.

I close this issue. If you have other problem, feel free to reopen. Thank you for using gopsutil.

ChrisSwanson · 2023-10-07T18:30:34Z

@Lomanic apologies for the delay in response here (can you please re-openn?)

I believe I attempted to do what you asked:

copied the contents of host/host_darwin_amd64.go to host/host_darwin_arm64.go
ran bash mktypes.sh
ran diff host_darwin_arm64.go ~/src/gopsutil/host/host_darwin_arm64.go to see no difference.
