Random Hangs & Pinwheels #205

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
First of all, if you have any Haxies, InputManagers, SIMBL plugins or
similar operating system hacks installed, please remove them first, restart
the program, and make sure the bug is reproducible without them.

What steps will reproduce the problem?
1. Open Image in directory with many images (all DSC_1234.JPG style)
2. Browse them (command-Left and Right)
3.

What is the expected output? What do you see instead?
Image opens part way, then mouse becomes pinwheel. Activity Viewer Inspect
-Process counts this as a "Recent Hang"

What version of the product are you using? On what operating system?
-Xee 2.1, OS 10.4.11, Dual 1GHz G4ll
Please provide any additional information below.
Xee 2.0 does no exhibit this behavior, additionally, Xee 2.0 feels faster
overall, as though something is "gumming up" 2.1.

Thanks! I appreciate such a cool, FREE app. You're awesome.

Unfortunately, that is not enough information to go on to fix anything, as I 
don't get that behavior on my 
machine at all.

If you can narrow it down to something more specific, that would help a lot.

I went back to 2.0 after posting this. But then I read your response, 
re-downloaded
the binary to snoop some more (I always wanted a good reason to use Shark....), 
and
it seems so much happier now. I fear some corruption must have been involved 
with the
first one. Thanks for looking into this anyway.

I got it to come back. Or, at least I managed to make a similiar behavior come 
back.

Some more background: there are about 2700 photos in this directory.

The hickup seems to be related to deleting an image. If I press command-delete 
to
move the current image to the trash, Xee loads the next image in the sequence 
and
shows it to me, however it will then pinwheel if I try to go back one in the
sequence. These pauses are about 30 seconds long.

I'm not sure this is my original problem... I'm sure i was just browsing the 
images
as quickly as they could be loaded.

I'm not clued in enough to be sure this is the right idea, but I have Shark Time
Profiles for this (3 of them) that seem to indicate that Xee is rebuilding and
sorting a list of files in the directory when this happens. I could send these 
to you
if you'd like.

You can post them as an attachment here. They might be useful. I'll see if I 
can recreate 
that too when I get back to working on Xee.

Here's the Shark traces I referred to

Thanks again!

I got a little more time to experiment. I think the problem is related to the 
number
of files in the directory. In a directory with fewer images in it (~20 in this 
case)
I can delete files and then load the next or previous image without much pause. 
Going
back to the thousands-of-files directory, the problem returns.

I think I finally managed to recreate this, too. I'll be looking into it.

Turns out it was pretty simple once I could reproduce it. For some reason, 
testing if an 
FSRef is valid is *really* slow, but the code should work without doing that, 
too, so I just 
removed the check.

Well, hopefully it works right. It's a lot faster, at least.
