From abc3a9efd1124d74155c6a70798d10710b20786d Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Fri, 12 Dec 2008 20:13:58 +0100 Subject: [PATCH] Drop private inotify code Quoting Adrian Bunk: "avahi-daemon ships with the contents of linux/inotify.h plus #define's for the syscall numbers. The latter are #if 0'ed. I'm not sure whether this setup could work at all with some kernel headers and glibc version, but considering that glibc already provides sys/inotify.h for some time it's IMHO time to drop the private inotify code." Original patch from Adrian Bunk. Closes #243. --- avahi-daemon/Makefile.am | 3 +- avahi-daemon/inotify-nosys.h | 181 ----------------------------------- avahi-daemon/main.c | 172 ++++++++++++++++----------------- configure.ac | 1 - 4 files changed, 85 insertions(+), 272 deletions(-) delete mode 100644 avahi-daemon/inotify-nosys.h diff --git a/avahi-daemon/Makefile.am b/avahi-daemon/Makefile.am index 622b4de..0aac0fc 100644 --- a/avahi-daemon/Makefile.am +++ b/avahi-daemon/Makefile.am @@ -53,8 +53,7 @@ avahi_daemon_SOURCES = \ static-hosts.c static-hosts.h \ ini-file-parser.c ini-file-parser.h \ setproctitle.c setproctitle.h \ - ../avahi-client/check-nss.c \ - inotify-nosys.h + ../avahi-client/check-nss.c avahi_daemon_CFLAGS = $(AM_CFLAGS) $(LIBDAEMON_CFLAGS) $(XML_CFLAGS) avahi_daemon_LDADD = $(AM_LDADD) ../avahi-common/libavahi-common.la ../avahi-core/libavahi-core.la $(LIBDAEMON_LIBS) $(XML_LIBS) diff --git a/avahi-daemon/inotify-nosys.h b/avahi-daemon/inotify-nosys.h deleted file mode 100644 index 6af44dc..0000000 --- a/avahi-daemon/inotify-nosys.h +++ /dev/null @@ -1,181 +0,0 @@ -/* - * This header is used if cannot be found. - * - * Inode based directory notification for Linux - * - * Copyright (C) 2005 John McCutchan - */ - -#ifndef _LINUX_INOTIFY_H -#define _LINUX_INOTIFY_H - -#include -#include -#include -#include - -/* - * struct inotify_event - structure read from the inotify device for each event - * - * When you are watching a directory, you will receive the filename for events - * such as IN_CREATE, IN_DELETE, IN_OPEN, IN_CLOSE, ..., relative to the wd. - */ -struct inotify_event { - int wd; /* watch descriptor */ - uint32_t mask; /* watch mask */ - uint32_t cookie; /* cookie to synchronize two events */ - uint32_t len; /* length (including nulls) of name */ - char name __flexarr; /* stub for possible name */ -}; - -/* the following are legal, implemented events that user-space can watch for */ -#define IN_ACCESS 0x00000001 /* File was accessed */ -#define IN_MODIFY 0x00000002 /* File was modified */ -#define IN_ATTRIB 0x00000004 /* Metadata changed */ -#define IN_CLOSE_WRITE 0x00000008 /* Writtable file was closed */ -#define IN_CLOSE_NOWRITE 0x00000010 /* Unwrittable file closed */ -#define IN_OPEN 0x00000020 /* File was opened */ -#define IN_MOVED_FROM 0x00000040 /* File was moved from X */ -#define IN_MOVED_TO 0x00000080 /* File was moved to Y */ -#define IN_CREATE 0x00000100 /* Subfile was created */ -#define IN_DELETE 0x00000200 /* Subfile was deleted */ -#define IN_DELETE_SELF 0x00000400 /* Self was deleted */ -#define IN_MOVE_SELF 0x00000800 /* Self was moved */ - -/* the following are legal events. they are sent as needed to any watch */ -#define IN_UNMOUNT 0x00002000 /* Backing fs was unmounted */ -#define IN_Q_OVERFLOW 0x00004000 /* Event queued overflowed */ -#define IN_IGNORED 0x00008000 /* File was ignored */ - -/* helper events */ -#define IN_CLOSE (IN_CLOSE_WRITE | IN_CLOSE_NOWRITE) /* close */ -#define IN_MOVE (IN_MOVED_FROM | IN_MOVED_TO) /* moves */ - -/* special flags */ -#define IN_ONLYDIR 0x01000000 /* only watch the path if it is a directory */ -#define IN_DONT_FOLLOW 0x02000000 /* don't follow a sym link */ -#define IN_MASK_ADD 0x20000000 /* add to the mask of an already existing watch */ -#define IN_ISDIR 0x40000000 /* event occurred against dir */ -#define IN_ONESHOT 0x80000000 /* only send event once */ - -/* - * All of the events - we build the list by hand so that we can add flags in - * the future and not break backward compatibility.
