Java API for CVS
전 우주적으로 가장 활발하게 사용하는 버전컨트롤 도구는 아마도 CVS일지도 모른다. 아니면 MS의 SourceSafe 정도? 보다 강력한 상용 형상관리 도구들이 있지만 발주처 빵빵하고 대규모 프로젝트 아니면 만져볼 기회 조차 없는 것이 현실이다. 또한, 이런 형상관리 도구는 대부분 Open API를 제공한다. 지금 몸 담고 있는 프로젝트에서도 CVS 써버를 4대로 구성하여 아주 빵빵하게(?) 돌리고 있는데, 이 마저도 느리고 모자라다고 난리다. 가끔 출몰하는 좀비 cvs.exe때문인데, 그 원인은 아직 밝혀내지 못 하고 있다. 혹시 아시는 분은 바로 댓글 달아주시면 감사하겠다.
아무튼 이야기가 시작하자마자 바로 옆으로 샛는데, 본론은 Java API를 이용한 CVS 핸들링이다. CVS와 연계하여 시스템적으로 무엇인가 처리해야 할 일이 있으면 아주 유용하게 쓸 수 있어 소개한다.
