Posting a multipart form with file data can break params assignment (in 2.3)

Reported by Jonathan Sutherland | February 4th, 2009 @ 03:26 PM

When posting a multipart form to create a record, posted attributes are not being included in the controller's params hash.

Example:

POST a Contact with a photo file and a name attribute; the :name key is not found in params => { contact => { ... } }

Update

I've found this issue occurs only when uploading .jpg files (thus far). No issues testing with .gif, .pdf, .ppt and .mov.

Possibly relevant: I'm running Mac OS X 10.5.6.

Steps to reproduce

1) Create a new rails project (Rails 2.3.0)


  $ rails -v
  Rails 2.3.0

  $ rails test
  $ cd test

2) Create a Contact scaffold with a "name"


  $ script/generate scaffold Contact name:string

3) Migrate the db


  $ rake db:migrate

4) Add a photo attr_accessor to the model for testing multipart posting


  # app/models/contact.rb
  class Contact < ActiveRecord::Base
    attr_accessor :photo
  end

5) Update the "new" view: (1) specify multipart, and (2) add file_field for the photo file (NOTE: photo file_field must come BEFORE name field in order to reproduce this issue!)


  # app/views/contacts/new.html.erb
  <% form_for(@contact, :html => { :multipart => true }) do |f| %>

    ...

    <p>
      <%= f.label :photo %><br />
      <%= f.file_field :photo %>
    </p>

    <p>
      <%= f.label :name %><br />
      <%= f.text_field :name %>
    </p>

    ...

6) Run the server


  $ script/server

7) Load the view (http://localhost:3000/contacts/new) and submit the form with a photo file and a name specified

8) Examine the server log: the name attribute is NOT included in the parameters hash and is NOT saved to the DB... FAIL!

    Hi,

    I tested in edge rails (clone from github), can't reproduce the problem.

    Jan,

    Ensure you test with <%= f.file_field ... %> appearing BEFORE <%= f.text_field ... %> in your view.

    Reproducing this issue is dependent on the order in which form parameters are posted.

  • Jonathan Sutherland

    Jonathan Sutherland February 4th, 2009 @ 05:39 PM

    Also,

    Appears to occur for .jpg files only (thus far). No issues testing with .gif, .pdf, .ppt and .mov.

    Possibly relevant: I'm running Mac OS X 10.5.6.

    I also see this behaviour on Mac OS X 10.5.6.

    I have used rake rails:freeze:edge to obtain the latest copy of edge.

    As far as I can see, something about jpg files causes the issue of missing form fields after the first f.file_field, whether it is uploaded in Firefox, Safari and Firefox on windows.

    Appears it may be a parsing issue in Rack's Utils::Multipart.parse_multipart.

    For a posted JPEG, use debugger to examine Utils::Multipart.parse_multipart as it parses through the posted data:

    
      /usr/local/lib/ruby/gems/1.8/gems/rack-0.9.1/lib/rack/utils.rb:341
      break  if buf.empty? || content_length == -1
    
      (rdb:4) head
      "ntent-Disposition: form-data; name=\"contact[name]\"\r\n"
    
      (rdb:4) name
      nil
    

    Looks like the header got parsed wrong: it's missing "Co" from "Content-Disposition". Thus, contact[name] isn't added to params as it's not matched by the corresponding regex:

    
      # rack-0.9.1/lib/rack/utils.rb:293
      name = head[/Content-Disposition:.* name="?([^\";]*)"?/ni, 1]
    

    ====

    For other posted file types (e.g. PDF), there's no issue:

    
      (rdb:5) head
      "Content-Disposition: form-data; name=\"contact[name]\"\r\n"
    
      (rdb:5) name
      "contact[name]"
     
      (rdb:5) params
      {"contact[name]"=>"Jonathan", "authenticity_token"=>"sd76bBiUOGsmSW... etc.

    Can you please test this issue against rack/master.

    I vendor it for the moment so we can test Rails against it before Rack 1.0 is released.

  • Chris Barnes

    Chris Barnes February 9th, 2009 @ 07:12 PM

    I verified this affects jpg files on OSX 10.5.6 with Firefox 2.0.0.12 and Safari 3.1.2. I tried to test against rack/master but I am unsure if I did it correctly.

    I did git submodule add git://github.com/chneukirchen/rack.git vendor/plugins/rack

    restarted my server and re-tested, the results were the same

    How do I tell if my application is using the rack installed in vendor/plugins?

  • Joshua Peek

    Joshua Peek February 9th, 2009 @ 08:06 PM

    O, my mistake. I meant to say with edge rails.

    I bundled rack into edge rails. You should be able to do rake rails:freeze:edge and try again.

  • Chris Barnes

    Chris Barnes February 9th, 2009 @ 09:35 PM

    Ok, I created a new app, froze to edge and tested again exactly as Johnathan did in his example and I get a 500 error "bad content body" You can find the full error at http://www.pastie.org/384389.

    Anything I can do to help, let me know. I would love to get this working.

  • Joshua Peek

    Joshua Peek February 9th, 2009 @ 09:40 PM

    • State changed from “new” to “open”

    This looks like a bug in Rack core.

    If your dying to jump on this, you can write a failing unit test against rack (http://github.com/rack/rack/blob... and submit it to http://rack.lighthouseapp.com/. You can actually still assign the ticket to me :)

    Otherwise I'll take a look at the issue closer towards the end of the week.

  • Joshua Peek

    Joshua Peek February 10th, 2009 @ 07:51 PM

    • State changed from “open” to “resolved”

    BINGO! Your on the 0.9.1 rack release. /Users/chris/.gem/ruby/1.8/gems/rack-0.9.1

    I think I fixed the vendored rack load path. Please try again, I suspect it will work fine.

  • Jonathan Sutherland

    Jonathan Sutherland February 10th, 2009 @ 08:04 PM

    Looks good Josh.

    Don't see this issue anymore with Rails edge + vendored Rack.

  • Chris Barnes

    Chris Barnes February 11th, 2009 @ 07:49 PM

    Awesome!

    I don't see this issues anymore with edge rails also.

  • Nick Quaranto

    Nick Quaranto February 12th, 2009 @ 03:37 AM

    I just ran into this issue myself, I had 2 file fields on the page and a textarea. Submitting the form with one or no files made Rails recognize the textarea, but submitting both file fields would make the textarea disappear from the params. After checking out the POST parameters to ensure it wasn't a browser issue, I figured it had to be an issue with Rails.

    Luckily, I found this thread but I have a feeling most developers won't. I can definitely make a blog post about it but perhaps something more public should be made known about this issue.

  • Michael Koziarski

    Michael Koziarski February 12th, 2009 @ 05:38 AM

    Nick, the fixes in this thread will be shipped as part of the second RC for rails 2.3, it'll be fixed before the releases are 'in the wild'

    I'm getting strange errors still with the latest Rails edge.

    http://gist.github.com/77057

    I've tried digging through the code, but I can't quite figure it out. It's happening in this file: rails/actionpack/lib/action_controller/vendor/rack-1.0/rack/utils.rb on line 298 and 330. It looks like rack.input.read is nil.

    I've tested this both using Passenger and Litespeed with the same effect.

  • Steve Martocci

    Steve Martocci April 7th, 2009 @ 10:32 PM

    I'm still getting this but it is hard to reproduce, I have one safari browser that is getting the errors. I am on a frozen v2.3.2.1 and passenger 2.1.3. Here is my stack trace

    I don't have Rack 0.9.1 installed and this has been marked as resolved? Does that mean there is a fix in edge/rack?

  • Evgeniy Pirogov

    Evgeniy Pirogov April 27th, 2009 @ 10:15 PM

    The problem was inside the Rack v0.9.1 utils.rb

    rx = /(?:#{EOL})?#{Regexp.quote boundary}(#{EOL}|--)/

    version 1.0 announced on Apr 25

    http://blade.nagaokaut.ac.jp/cgi...

    has this regexp fixed rx = /(?:#{EOL})?#{Regexp.quote boundary}(#{EOL}|--)/n

    the last modifier tells ruby to use regexp on a binary stream, rather then on the default kcode (which is utf8 under rails).

    and as a result the last byte in the jpg was joined with \r byte and it generates wrong match for

    i = buf.index(rx)

    and two extra-bytes where cut from stream and added to the file

    uploaded file

    ls -l /home/epirogov/469792-20090427134009-945951-328497.jpeg -rw-r--r-- 1 epirogov epirogov 577926 2009-04-27 08:02 /home/epirogov/469792-20090427134009-945951-328497.jpeg

    temp rack file epirogov@ep:/opt/ror/uping$ ls -l /tmp/RackMultipart.28044.0 -rw------- 1 epirogov epirogov 577928 2009-04-27 16:54 /tmp/RackMultipart.28044.0

    the left over of the buf becomes

    "-----------------------------16244688581190744854224487137\r\nContent-Disposition: form-data; name="tags"\r\n\r\n12 12 12 12 \r\n-----------------------------16244688581190744854224487137\r\nContent-Disposition: form-data; name="submit"\r\n\r\nSubmit\r\n-----------------------------16244688581190744854224487137--\r\n"

    Notice absence of \r\n in front, and after buf.slice!(0, boundary_size+2)

    buf lost 'Co'.

    after updating rack to 1.0 and restarting passenger problem went away

    Seems, that the error is still in Rack 1.0.
    I have a multipart Form for video-file-upload. The upload runs into errors on a Linux Gentoo Machine. On Max OS X all is fine.

    Rails Version is 2.3.2, Mongrel 1.5. Ruby 1.8.

    Has anybody a solution for this issue?

    Best Regards.

    I don't think this is resolved.

    In Rack1.0, I still have issues where the multi-part parser incorrectly handles "\r\n--\r\n". Rack doesn't like the leading "\r\n", but only on internal boundaries, the ends still need the proper leading and trailing \r\n's.

    I have the same issue as well. Rails 2.3.2, Ruby 1.8.6.
    I get the following error with multipart post, and it only happens with Safari3. I used Rack 1.0.0 tag from github.

    We're seeing this as well, but only on Safari 3.0.4. 3.1.2 and 3.2.1 and 4.x work fine.

    Seems that the multipart POST goes through fine but the subsequent 302 redirect maintains the multipart form boundary even though there is not multipart.

    I've attached a http dump of what's happening on our side. Notice there's a boundary declaration in the content-type but no actual boundary. Hence the bad content body message.

    • Tag changed from multipart, upload to failsafe, multipart, rack, upload
    • Importance changed from “” to “”

    Hi,

    I am having this as well, with GET requests that may or may not subsequently get redirected by a login before_filter. The error always ocurs in rack-1..1/lib/rack/utils.rb:319 in "parse_multipart", although with a simple GET request, there should be no multipart to parse (right?).

    It is also strange that in rack/request.rb, the POST method is called, although there was never a POST. Also, most(!) requests I receive that trigger this error come from Googlebots. But not all.

    Running Passenger 2.2.5 and Rails 2.3.5, with Rack 1.0.1 on Apache 2.2.3 on Debian 5.0.

    Any help would be appreciated. Root path for the output below is /opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/ (cropped for better readability).

    I'm seeing this error again in production under rails 2.3.10 and passenger 3.0.3 under apache. The upgrade from passenger 2 is the only thing that has changed.

    Users are attempting to upload largish files (2-8mb). Most work, some fail; it's intermittent. The Rack version in use is 1.1.0.

    I don't know how to test Rails with Rack 1.2.1 to see if this is resolved in that version, as rack is loaded before environment.rb is run. If I try to force it by uninstalling Rack 1.1, I get the warning that the dependencies for rails 2.3.10 will break.
