Deprecation: run_command and popen4 helper method removal (OHAI-3)
Ohai ships a command mixin for use by plugin authors in shelling out to
external commands. This mixin originally included
popen4 methods, which were deprecated in Ohai 8.11.1 (Chef Infra Client
12.8.1) in favor of the more robust
mixlib-shellout gem functionality.
In Chef Infra Client 13 these deprecated methods will be removed, breaking any
Ohai plugins authored using the deprecated methods.
Plugins should be updated to use mixlib-shellout instead of the run_command.
Deprecated run_command based code:
status, stdout, stderr = run_command(command: 'myapp --version') if status == 0 version = stdout end
Updated code for mixlib shellout:
so = shell_out('myapp --version') if so.exitstatus == 0 version = so.stdout end
See the mixlib-shellout repo for additional usage information.
