Error with data:uri

[ai]

We encode some images with data:uri and put it directly in CSS file (by SASS inline-image function).

But yui-compressor throw error on this CSS-files: /compressor.rb:87:incompress': compression failed (YUI::Compressor::RuntimeError)`

If I put puts stderr.read in compress method, I see YUI error:

Exception in thread "main" java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)
    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)
    at java.lang.reflect.Method.invoke(Method.java:616)
…

So, as I understand, YUI 2.4.4 have problem with data:uri images in CSS.

I already wrote a couple of times before:

Since january 18 (0.9.3, 0.9.4) ruby-yui-compressor is bundled with yui compressor 2.4.4 (although current official version 2.4.2) and this version can't compress stylesheet if it contains an embedded image (i've checked with 16kb image).

So I suggest to rollback to official stable version of yui-compressor for now.

I tried to convert my css file with inline data with the yui jar from the command line and got a stackoverflow exception. Increasing the stack size of the java vm solved this problem for me.

Unfortunately ruby-yui-compressor currently has no configuration to manipulate the java runtime so I had to monkeypatch it.

class YUI::Compressor
  def command
    @command.insert 1, "-Xss8m"
    @command.map { |word| Shellwords.escape(word) }.join(" ")
  end
end

+1, Increasing the java vm stack size works

See also #9, which allows passing in VM flags in via the options hash.

It has helped me to use the YUI Compressor from https://github.com/schleyfox/yuicompressor
Just check it our, use ant to build it and replace ruby-yui-compressor's version of the jar with the freshly build one.

[wizztjh]

@css_compressor = YUI::CssCompressor.new(Jammit.css_compressor_options || {})

#9
YUI::JavaScriptCompressor.new(:java_opts => '-Xmx64M')

so i think this will solve it , but #9 is not merge into master

#asset.yml
compressor_option: 
  java_opts: "-Xss64m"
css_compressor_options: 
  java_opts: "-Xss64m"

I also ran into this issue with SASS stylesheets - hopefully #9 will be merged soon so that this issue can be resolved!

Yep. Just found this. Bad times.

Guys. It should work now with YUI Compressor 2.4.7 http://yuilibrary.com/forum/viewtopic.php?f=94&t=7237&p=31853

With 2.4.6 I got a StackOverflowException with data URIs too. Do you know what Maven repository I can download 2.4.7 from?

[stevecrozz]

I haven't had a chance to write a test case yet for this issue, but you may want to try upgrading to v0.11.0 of this gem which includes yuicompressor 2.4.7

[stevecrozz]

I added a test case to make sure no exceptions are raised when processing a data URI in CSS. fc91491

The test case is passing, but I actually can't make it fail even going back to the earliest versions of the yuicompressor jar that were used in this project. Please reach out if you have a failing test case you can contribute.
