그대는 원하지도 않는 수많은 일을 계속한다

Tuesday, March 27th, 2012

그대는 원하지도 않는 수많은 일을 계속한다. 누가 그대를 강요하는가? 그대는 표류하고 있다. 아무도 그대를 강요하지 않는다. 그대는 왜 그런 일들을 하는가? 그대는 깨어 있지 못하다. 이것은 사슬과 같다. 한 가지 일을 하면 또 다른 일이 생겨난다. 하나의 일이 다른 일을 끌어오고, 이런 식으로 계속된다. 그대는 언제 멈출 것인가? 매순간이 멈추기에 알맞은 순간이다. 관찰하라. 그리고 그대 스스로 만든 이 거짓의 연결 고리에서 벗어나라.

Play! 프로세스 제목이 너무 길어서

Saturday, March 10th, 2012

Play! framework에 한가지 불만이 있다면 $ ps -ef | grep play.server 의 결과가 너무 길다는 것이다. 내 개발환경에서는 4KB가 넘는다.

$ ps -ef | grep play.server

프레임워크에서 제공하는 각 모듈들이 절대경로로 들어가 있어서 서버에서 돌고 있는 java 프로세스들을 확인하기 위해 ps -ef | grep java 만 하더라도 짜증이 솟구치게 된다.

그래서 Python으로 작성된 구동 스크립트에서 classpath를 환경변수로 떼버리도록 살짝 고쳤다.

$PLAY/framework/pym/play/utils.py 파일에 추가

def detach_classpath(cmd):
  i = cmd.index('-classpath')
  classpath = cmd[i+1]
  del cmd[i+1]
  del cmd[i]
  env = os.environ
  env['CLASSPATH'] = classpath
  return cmd

이제 $PLAY/framework/pym 에서

$ grep -rn "subprocess.Popen" play/commands
./play/commands/base.py:139:        process = subprocess.Popen(java_cmd, env=os.environ)
./play/commands/base.py:214:        play_process = subprocess.Popen(java_cmd, env=os.environ, stdout=sout)
./play/commands/daemon.py:47:        pid = subprocess.Popen(app.java_cmd(args), stdout=sout, env=os.environ).pid
./play/commands/daemon.py:90:        pid = subprocess.Popen(java_cmd, stdout=sout, env=os.environ).pid

로 검색하여 각 Popen 첫번째 인자를 아래와 같이 detach_classpath로 묶어준다.

subprocess.Popen(detach_classpath(app.java_cmd(args)), stdout=sout, env=os.environ).pid

detach_classpath 함수의 목표는 java_cmd 리스트에서 -classpath 다음 요소를 찾아 os.environ[‘CLASSPATH’]에 넣고 원래 list에서는 이를 지워버리는 것이다. os.environ을 런타임에 조작하는 애드혹 패치를 저지르긴 했지만 child process에게 넘겨질 os.environ을 수정하는 것이므로 별다른 문제는 없다.
