dnotify is a file system event monitor for the Linux kernel, one of the subfeatures of the fcntl call. It was introduced in the 2.4 kernel series. It has been obsoleted by inotify, but will be retained for compatibility reasons. Its function is essentially an extension to filesystems to notice changes to the filesystem, and report those changes to applications. Instead of application checking for changes to filesystem, application can register to be notified by kernel when changes to filesystem occur. Application can select directories to monitor and types of changes to be notified for. One major use is in desktop search utilities like Beagle, where its functionality permits reindexing of changed files without scanning the filesystem for changes every few minutes, which would be very inefficient. By being told that a file has changed directly by the kernel, rather than actively looking, Beagle and such utilities can achieve change-to-reindexing times of only about a second, with very small performance hits (dnotify therefore enables the use of such programs in a sensible manner; daemons are generally not accepted by distributors if they drain system performance noticeably to provide userland functionality). (en) dnotify는 리눅스 커널에 들어간 일종의 파일 시스템 이벤트 모니터이다. fcntl 시스템 콜의 한 부수적인 기능이었다. 리눅스 2.4 커널 시리즈에서 도입되었다.. dnotify는 후에 inotify에 의해 대체되었다. 하지만, 하위 호환성 유지를 이유로 계속 남아 있을 전망이다. (ko) |
