gamin doesn't notice local file creation on NFS4

[Valentijn Sessink]

Binary package hint: gamin

Gamin Version: 0.1.9-2ubuntu2 (Ubuntu 8.04) seems to not notice file creation events on an NFS4 share. It *does* recognize local file creation under NFS version 3.

First, we'll mount with NFSv3:
machine# mount -t nfs server:/home /mnt/
machine$ gvfs-monitor-dir /mnt/valentyn/

[ in other terminal: ]machine$ touch /mnt/valentyn/demofile

Directory Monitor Event:
Child = /mnt/valentyn/demofile
Event = CREATED
Directory Monitor Event:
Child = /mnt/valentyn/demofile
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/valentyn/demofile
Event = CHANGES_DONE_HINT

Now, we'll try this again with nfsv4:
machine# mount -t nfs4 server:/home /mnt/
machine$ gvfs-monitor-dir /mnt/valentyn/

[ in other terminal: ]machine$ touch /mnt/valentyn/demofile

Directory Monitor Event:
Child = /mnt/valentyn/demofile
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/valentyn/demofile
Event = CHANGES_DONE_HINT

As you see, the ATTRIB CHANGED and CHANGES_DONE_HINT events show up, but the CREATED event is missing.

This only goes for files, if you create a directory, it will show up immediately (as expected).

It would be great if this issue could be confirmed with the most recent gamin version 0.1.10-1ubuntu1 available in the latest Karmic alpha release:

https://edge.launchpad.net/ubuntu/+source/gamin/0.1.10-1ubuntu1/+build/1060326

Although I'm not sure if this bug would qualify for a Stable Release Update for Hardy, in order for any bug to qualify for a Stable Release Update it must be confirmed as fixed in the actively developed release (ie Karmic). See https://wiki.ubuntu.com/StableReleaseUpdates for more information. Please let us know your results. Thanks.

I can confirm the bug in jaunty, it's the same behavior Valentijn described:

--- with nfs3
ubuntu# mount -t nfs server:/export /mnt/
ubuntu$ gvfs-monitor-dir /mnt/ubuntu/

ubuntu$ touch /mnt/ubuntu/aaa

Directory Monitor Event:
Child = /mnt/ubuntu/aaa
Event = CREATED
Directory Monitor Event:
Child = /mnt/ubuntu/aaa
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/ubuntu/aaa
Event = CHANGES_DONE_HINT

--- with nfsv4:
ubuntu# mount -t nfs4 server:/export /mnt/
ubuntu$ gvfs-monitor-dir /mnt/ubuntu/

ubuntu$ touch /mnt/ubuntu/bbb

Directory Monitor Event:
Child = /mnt/ubuntu/bbb
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/ubuntu/bbb
Event = CHANGES_DONE_HINT

Next I'm going to test gamin version 0.1.10-1ubuntu1 in Karmic as of Leann's comment.

[Dragomir Minkovski (dejuren)]

Same with Karmic, bug is still alive:

--- with nfs3
ubuntu# mount -t nfs server:/export /mnt/
ubuntu$ gvfs-monitor-dir /mnt/ubuntu/

ubuntu$ touch /mnt/ubuntu/ccc

Directory Monitor Event:
Child = /mnt/ubuntu/ccc
Event = CREATED
Directory Monitor Event:
Child = /mnt/ubuntu/ccc
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/ubuntu/ccc
Event = CHANGES_DONE_HINT

--- with nfsv4:
ubuntu# mount -t nfs4 server:/export /mnt/
ubuntu$ gvfs-monitor-dir /mnt/ubuntu/

ubuntu$ touch /mnt/ubuntu/ddd

Directory Monitor Event:
Child = /mnt/ubuntu/ddd
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/ubuntu/ddd
Event = CHANGES_DONE_HINT

[Valentijn Sessink (valentijn)]

Still there in Ubuntu 10.04 (Lucid)

[Dragomir Minkovski (dejuren)]

Confirming with Lucid alpha 3

--- with nfs3:
$mount -t nfs server:/export /mnt

$mount
server:/export on /mnt type nfs (rw,addr=10.153.108.235)

gvfs-monitor-dir /mnt/

Directory Monitor Event:
Child = /mnt/aaa
Event = CREATED
Directory Monitor Event:
Child = /mnt/aaa
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/aaa
Event = CHANGES_DONE_HINT

--- with nfsv4:
$ mount -t nfs4 server:/export /mnt

$ mount
server:/export on /mnt type nfs4 (rw,clientaddr=10.153.108.152,addr=10.153.108.235)

gvfs-monitor-dir /mnt/
Directory Monitor Event:
Child = /mnt/aaa
Event = ATTRIB CHANGED
Directory Monitor Event:
Child = /mnt/aaa
Event = CHANGES_DONE_HINT

Still present at least as recently as 12.04.3; will test something newer (especially considering recent changes in glib) when I get a chance.

[Ryan Tandy (rtandy)]

Looks to be fixed in trusty. Can anyone else affected confirm that?

$ rm test

Marking fixed in gvfs. I don't know how to test gamin.
