Bug 2387829

I didn't see a spot to upload my journalctl -b output. I have it, just cannot upload it.

Hey Phil,

Thanks for the report. Interestingly, this isn't WSL-specific and `uname -p` reports unknown on both Fedora Workstation and a Debian Trixie container. It's properly reported in Ubuntu 24.04 containers so my first guess is this is a coreutils bug introduced between 9.3 and 9.6. Running `strace uname -p` shows it never even calls `uname(2)`:

But it's not like `uname(2)` is broken since the following program works:

dev in ~/tmp via C v15.1.1-gcc 
❯ cat test.c 
#include <stdio.h>
#include <sys/utsname.h>

int main () {
	struct utsname details;
	
	int ret = uname(&details);
	if (ret != 0)
		return ret;

	printf("Detected arch %s", details.machine);
	return 0;
}

dev in ~/tmp via C v15.1.1-gcc
❯ ./test
Detected arch x86_64⏎

I'm still waiting for the coreutils repository to clone, but looking at the manual page, `uname` has a `-m` option that prints the architecture, and `-p` says "print the processor type (non-portable)". Maybe non-portable is code for "just prints unknown" since -m works. It's possible `go-task` needs a fix to use -m.

I wheeled over to my Fedora Silverblue/Kinote installs, and they also give an unknown result with uname -p and the x86_64 with uname -m. 

I don't know much about go-task under the surface.

Okay, so the issue with go-task has been fixed in https://bodhi.fedoraproject.org/updates/FEDORA-2025-585cfc0d61.

Looking at the coreutils code, it'll print unknown for `-p` in most cases. I've not unpacked all the #ifdefs but yeah, things should just use `-m` it seems.

I'll make a backup of my WSLv2 Distribution and give this a try.

Made a backup, and ran the command in the linked page you gave. Nothing happened.

Weird. It sure doesn't do anything. I'll go chase that down separately, I suppose.

You can run this instead: `sudo dnf upgrade --enablerepo=updates-testing go-task`

That did update to a newer version and go-task did work as intended.

Usage: task [flags...] [task...]

Runs the specified task(s). Falls back to the "default" task if no task name
was specified, or lists all tasks if an unknown task name was specified.

Example: 'task hello' with the following 'Taskfile.yml' file will generate an
'output.txt' file with the content "hello".

'''
version: '3'
tasks:
  hello:
    cmds:
      - echo "I am going to write a file named 'output.txt' now."
      - echo "hello" > output.txt
    generates:
      - output.txt
'''

Options:
  -c, --color                       Colored output. Enabled by default. Set flag to false or use NO_COLOR=1 to disable. (default true)
      --completion string           Generates shell completion script.
  -C, --concurrency int             Limit number of tasks to run concurrently.
  -d, --dir string                  Sets the directory in which Task will execute and look for a Taskfile.
  -n, --dry                         Compiles and prints tasks in the order that they would be run, without executing them.
  -x, --exit-code                   Pass-through the exit code of the task command.
      --experiments                 Lists all the available experiments and whether or not they are enabled.
  -f, --force                       Forces execution even when the task is up-to-date.
  -g, --global                      Runs global Taskfile, from $HOME/{T,t}askfile.{yml,yaml}.
  -h, --help                        Shows Task usage.
  -i, --init                        Creates a new Taskfile.yml in the current folder.
      --insecure                    Forces Task to download Taskfiles over insecure connections.
  -I, --interval duration           Interval to watch for changes.

  -o, --output string               Sets output style: [interleaved|group|prefixed].
      --output-group-begin string   Message template to print before a task's grouped output.
      --output-group-end string     Message template to print after a task's grouped output.
      --output-group-error-only     Swallow output from successful tasks.
  -p, --parallel                    Executes tasks provided on command line in parallel.
  -s, --silent                      Disables echoing.

Great, I appreciate you testing that out. Based on my reading, `uname -p` is "working" as intended (although it is weird, and I'm sure there's some terrifying history behind why it is the way it is), so I'm marking this as a duplicate of the go-task bug. Thanks again for taking the time to report the issue.
