There's a large refactor of this module in the pipeline, and renaming from 'kill' to 'process' makes the API more sensible.
This is another name-only change ahead of some larger refactoring of the kong.cmd.utils.process module.
This refactors kong.cmd.utils.process to use the resty.signal library for sending signals instead of dropping to a shell. This comes with improvements (albeit minor) to performance and security.

Primary improvements:
os.execute()
for sending signalsSome months ago I needed to look over the code in
kong/cmd/utils/kill.lua
and thought to myself "we can do better than os.execute() here." At long last, here are the improvements that stemmed from that thought.Along the way I renamed the file to
kong/cmd/utils/process.lua
and changed the name of theis_running()
function toexists()
for aesthetic reasons. This and the other API changes to the file make the PR somewhat large, but these changes were done in separate commits, so review commit-by-commit if you want to have an easier read-through of the changes.There was a flaky test in
spec/02-integration/01-helpers/03-http_mock_spec.lua
that was giving me trouble. It was actually related to this problem domain (waiting for a pidfile to exist and contain a PID), so I fixed it here as well.Re-do #11382 without squashing, merge after #11620
