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 run_command
and
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.
Remediation
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.
