This is a temporary workaround for umount returning before the cache has been flushed (which causes for example files not being written to the disk), a proper solution is being worked on. - Add note in pkg-message about "stop" rc.d command unmounting FUSE filesystems. >How-To-Repeat: >Fix: --- fusefs-kmod.diff begins here --- Index: fusefs-kmod/Makefile =================================================================== RCS file: /home/pcvs/ports/sysutils/fusefs-kmod/Makefile,v retrieving revision 1.16 diff -u -r1.16 Makefile --- fusefs-kmod/Makefile 15 Nov 2007 19:46:42 -0000 1.16 +++ fusefs-kmod/Makefile 17 Dec 2007 03:34:41 -0000 @@ -7,7 +7,7 @@ PORTNAME= fusefs DISTVERSION= 0.3.9-pre1 -PORTREVISION= 2 +PORTREVISION= 3 CATEGORIES= sysutils kld MASTER_SITES= http://fuse4bsd.creo.hu/downloads/ \ http://am-productions.biz/docs/ Index: fusefs-kmod/files/fusefs.in =================================================================== RCS file: /home/pcvs/ports/sysutils/fusefs-kmod/files/fusefs.in,v retrieving revision 1.4 diff -u -r1.4 fusefs.in --- fusefs-kmod/files/fusefs.in 30 Oct 2007 03:10:09 -0000 1.4 +++ fusefs-kmod/files/fusefs.in 17 Dec 2007 03:34:41 -0000 @@ -25,13 +25,31 @@ fusefs_start() { + if kldstat | grep -q fuse\\.ko; then + echo "${name} is already running." + return 0 + fi echo "Starting ${name}." kldload $kmod } fusefs_stop() { + if ! kldstat | grep -q fuse\\.ko; then + echo "${name} is not running." + return 1 + fi echo "Stopping ${name}." +# Unmount FUSE filesystems in reverse order (in case they are nested) with +# a delay of one second after, to allow 'umount' finish. + mount | sed -e '1!G;h;$!d' | while read dev d1 mountpoint d2; do + case "$dev" in + /dev/fuse[0-9]*) + echo "fusefs: unmounting ${mountpoint}." + umount $mountpoint ; sleep 1 + ;; + esac + done kldunload $kmod } load_rc_config $name Index: fusefs-kmod/files/patch-fuse_io.c =================================================================== RCS file: fusefs-kmod/files/patch-fuse_io.c diff -N fusefs-kmod/files/patch-fuse_io.c --- /dev/null 1 Jan 1970 00:00:00 -0000 +++ fusefs-kmod/files/patch-fuse_io.c 17 Dec 2007 03:34:41 -0000 @@ -0,0 +1,11 @@ +--- fuse_module/fuse_io.c.orig Tue Jun 19 09:35:22 2007 ++++ fuse_module/fuse_io.c Thu Dec 13 02:46:05 2007 +@@ -148,7 +148,7 @@ + } + + if (uio->uio_resid == 0) +- return (0); ++ goto out; + + if (uio->uio_rw == UIO_WRITE && fp->f_flag & O_APPEND) { + if ((err = VOP_GETATTR(vp, &va, cred, td))) Index: fusefs-kmod/files/patch-mount_fusefs-mount_fusefs.c =================================================================== RCS file: /home/pcvs/ports/sysutils/fusefs-kmod/files/patch-mount_fusefs-mount_fusefs.c,v retrieving revision 1.1 diff -u -r1.1 patch-mount_fusefs-mount_fusefs.c --- fusefs-kmod/files/patch-mount_fusefs-mount_fusefs.c 13 Aug 2007 10:48:41 -0000 1.1 +++ fusefs-kmod/files/patch-mount_fusefs-mount_fusefs.c 17 Dec 2007 03:34:41 -0000 @@ -1,6 +1,15 @@ ---- mount_fusefs/mount_fusefs.c Sat Jul 14 13:12:09 2007 -+++ mount_fusefs/mount_fusefs.c Sat Jul 14 13:12:09 2007 -@@ -469,7 +469,8 @@ showversion(void) +--- mount_fusefs/mount_fusefs.c.orig Tue Jun 19 09:35:22 2007 ++++ mount_fusefs/mount_fusefs.c Thu Dec 13 02:44:12 2007 +@@ -70,6 +70,8 @@ + { "user_id=", 0, 0x00, 1 }, + { "group_id=", 0, 0x00, 1 }, + { "large_read", 0, 0x00, 1 }, ++ /* "nonempty", just the first two chars are stripped off during parsing */ ++ { "nempty", 0, 0x00, 1 }, + MOPT_STDOPTS, + MOPT_END + }; +@@ -469,7 +471,8 @@ int init_backgrounded(void) { @@ -9,3 +18,4 @@ + size_t len; len = sizeof(ibg); + Index: fusefs-kmod/files/pkg-message.in =================================================================== RCS file: /home/pcvs/ports/sysutils/fusefs-kmod/files/pkg-message.in,v retrieving revision 1.1 diff -u -r1.1 pkg-message.in --- fusefs-kmod/files/pkg-message.in 30 Oct 2007 03:10:09 -0000 1.1 +++ fusefs-kmod/files/pkg-message.in 17 Dec 2007 03:34:41 -0000 @@ -12,4 +12,9 @@ /etc/fstab with the "late" parameter.
