Paperclip crashes Ruby interpreter 1.9.2

[zarapustra]

Ruby interpreter frequently crashes when viewing images called with the @user.photo.url method from paperclip. Requires me to restart the server. Sometimes the view shows up fine, I hit F5 without making any changes to any code and it crashes.

Upload is working fine.

Using Ruby 1.9.2 and Rails 3 on Windows 7 x64 (also 32x)

That sounds pretty bad. Can you paste your has_attached_file and your Gemfile here? Also, what version of Paperclip are you using? Thanks.

[zarapustra]

has_attached_file :photo, :styles => { :medium => "150x200", :thumb => "100x>" }

Using paperclip (2.4.5)

Sorry for leaving you hanging. Is this still a problem? We haven't seen any problems in the meantime and we're using 1.9.2 and Rails 3. Could you supply a stacktrace when the error occurs?

[zarapustra]

there's no reaction in stacktrace when the error occurs. no signs that "something's rotten in the state of Denmark"

[jyurek]

I'm a little confused, then. How do you know it's a paperclip problem? What does happen? Does it hang? That's not quite the same as crashing, which would give you a stack trace.

[zarapustra]

this problem appeared when i started using paperclip. of course I may be mistaken. i'll show you win7's crash window of ruby interpreter. and i'll turn off paperclip to test app without it.

when i browsing pages that have no images, no crashes appear.

[jyurek]

Huh, that's a hell of a crash!

Ok, so we're kinda shooting in the dark, then. Just to reduce variables, we should generate as small an app as we can and see what happens. I suppose running the full test suite including the features would work, since they build small apps. I guess one of two things. One, it works, so points to interactions with another gem (not likely, but perhaps). Or two, it doesn't work, and so for some reason your Ruby is messed up and needs to be reinstalled. I only mention this because this is the first report of paperclip crashing the process and not just throwing an uncaught exception.

[zarapustra]

what can i do in order to help?

[jyurek]

You can make a small app on your machine, as small as it needs to be to view an image in a way that would trigger the crash. This will help us isolate the problem.

[nycdavid]

I had this exact same problem.

The way I fixed it was by specifying something different for the :path in the has_attached_file hash. I think it might be something about the images being served out of the public folder that's causing the Ruby interpreter to crash.

The has_attached_file in my Model reads:

has_attached_file :sideimg :url => "/assets/:basename.:extension" end

Thus, accessing the @image.sideimg.url attribute would render: /assets/ and concatenate whatever the file_name is that's stored in the db.

I'm running Rails 3.1.3 on Windows 7, so maybe the Asset Pipeline and Paperclip are conflicting? No idea.

Hope this helps.

[kapelner]

The problem is Windows not paperclip. This is a documented issue with Ruby 1.9.2 and multi-threading. Supposedly it's fixed for 1.9.3

[zarapustra]

I confirm this. Thanks for help!
