300044 - [OS BUG][10.4] serious system stablity problems require restart after drag image or link to application Dock

Status: VERIFIED INVALID

(Camino Graveyard :: Drag & Drop, defect)

Description

[Shawn Smith]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b2) Gecko/20050707 Camino/0.9a1+
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b2) Gecko/20050707 Camino/0.9a1+

If I drag an image from Camino to iPhoto 5 in the dock and iPhoto is not started
I crash the dock and then proceed to beachball Camino.  This leads to all
applications becomming hung and then to complete system stablity problems
(beachballs on all apps) requiring a reboot.

Reproducible: Always

Steps to Reproduce:
1.  Launch Camino
2.  Drag image to iPhoto 5 icon in dock (iPhoto not running)

Actual Results:  
Dock crashes and restarts.  Camino continues with a beachball with all
applications becoming unstable shortly thereafter resulting in the need for a
reboot to regain stablity.

Expected Results:  
iPhoto should launch and import the photo to the libary.  Expected results can
be seen with Safari.

Running on Tiger 4.0.1.  iBook G4.

FWIW, dragging an image to iPhoto is not supposed to work (see bug 193950), but
Camino shouldn't be hanging, either.

Reporter, please *attach* a sample of Camino while it's hanging. 
/Applications/Utilities/Activity Monitor, select Camino, click "Inspect" then
click "Sample", save the resulting sample as a text file and attach to this bug
via the "Create a New Attachment" link above.

this is what i thought. if the dock crashes, the drag won't complete and it'll
spin until it does. the OS *should* time out and cancel the drag automatically
after some length of time. If you let it sit, does everything eventually come
back to normal?

Comment 5

[Mike Pinkerton (not reading bugmail)]

the fact that we can destabilize the OS has been filed as rdar://4174164 (it
also happens if you drag a link from the content area to safari's dock icon).

we still need to figure out what we're doing wrong to the pasteboard that could
cause this in the first place.

Another way I've found to get out of some drag-hangs is to initiate another
drag. The OS apparently only keeps track of one drag at a time (which makes sense).

I am experiencing the exact same symptoms also when dragging an xml file from
the Camino content area to an application dock icon. After the drag the dock
immediatly crashed and Camino beachballs. I terminate Camino via the PID via the
Command Line as the CPU load increase prevents me from ctrl-clicking
effectively. The system become destabilized, apps don't load and the dock is
non-functional forcing a system reboot. Test cases included using Mail.app and
Newsfire.app

There is something screwy in the Pasteboard code and it's hanging Camino in
DragDispose. I've attached a crash reporter profile which may help to identify
what is going wrong at the receiver end.

Someone should file this bug with Apple.

Mike has filed it already under rdar://4174164

I hope you don't mean me. It's not on my list of radar bugs that I have filed
with apple. What's the title of that radar id?

oh, i think stuart filed that. sorry.

I got the same issue here when dragging a image in photoshop in the dock.

We shouldn't have so many problems with dragging images to the dock. Nominating for 1.0. (FF has a similar bug, bug 301619)

I don't think we can do anything about this.

This bug got some play yesterday at macosxhints: http://www.macosxhints.com/article.php?story=2005111007052983

The drag operations only "work" on 10.4, which explains why I've never been able to reproduce it....

Mike (comment 5): we still need to figure out what we're doing wrong to the pasteboard that could cause this in the first place.

Steve Jacobs (comment 8): There is something screwy in the Pasteboard code and it's hanging Camino in DragDispose. I've attached a crash reporter profile.

Both seem (to me!) to indicate there's something we're doing that is at least part of the problem.

I've been witness to this same bug affecting the Firefox 1.5 beta and RC series. Is anyone else noticing that it's not peculiar to Camino?

Comment 21

[Simon Fraser [no longer active]]

This is an OS bug that we can't do anything about. Someone should test to see if the latest software update fixes it.

Comment 22

[Shawn Smith]

Hard to believe it is an OS bug when it works just fine from Safari.  Perhaps someone should review the safari code and compare it to the FF 1.5 and Camino Code?

Maybe it depends on what you put on the pasteboard.

Comment 24

[Shawn Smith]

Hmm, same test from Safari and Camino/FF.  I drag an image from a Flickr web page to the iPhoto Dock Icon.  With Safari it launches import and works.  With FF/Camino I get a beachball and instabiliy.

??

Don't think the content matters it is something wrong with the FF/Camino Paste Code I think.

Tested under latest software updates, and it still hangs.

Comment 26

[Stuart Morgan]

If a Camino action destablizes system processes, there is by definition an OS bug. As previously mentioned, it has already been filed.

There are lots of ways to put things onto the pasteboard (which is probably what Simon meant by it depending on what you put there), and just because the way Safari does it works doesn't mean that a) it's practical to do it the same way it gecko, and b) that gecko is necessarily doing anything wrong.

Follow pink's precedent in bug 223315, moving to Future (and retitling) so dupes are less likely to be filed.

Comment 27

[Stuart Morgan]

Fixed in 10.4.4.  Closing.

This has been relnoted.
