enable xdebug then rr workers doesn't show any info

[lanphan]

Hello,
After I add some config to enable xdebug, I found that my command ./rr workers shows nothing, is it considered a bug?

My .rr.yaml:

version: '2.7'

rpc:
  listen: tcp://127.0.0.1:6001

status:
  address: 127.0.0.1:2114

server:
  command: "/usr/local/bin/php /source_code/worker.php"
  relay: "pipes"
  relay_timeout: "20s"
  env:
    XDEBUG_SESSION: 1

grpc:
  listen: "tcp://0.0.0.0:9001"
  proto: ${PROTO}

  max_send_msg_size: 50
  max_recv_msg_size: 50
  max_connection_idle: 0s
  max_connection_age: 0s
  max_connection_age_grace: 0s
  max_concurrent_streams: 10
  ping_time: 1s
  timeout: 200s

  pool:
    num_workers: ${NUM_WORKERS}
    max_jobs: ${MAX_JOBS}
    allocate_timeout: ${ALLOCATE_TIMEOUT}
    destroy_timeout: 60
    debug: true

logs:
  mode: development
  encoding: console
  level: debug
  output: stderr

metrics:
  address: 127.0.0.1:2112

My command ./rr workers output:

solved from discord

remove grpc.pool.debug key from configuration (xdebug still can work normally)

Reason:

There are no workers in the debug mode. Worker created right after you made a request and destroyed after the response has been sent to the user.
Thus, you see an empty output from the rr worker command.
