I recently upgrade Ruby from 1.8.5 to 1.8.6. With 1.8.5, gsub handled a
fixnum just fine but choked on it in 1.8.6. Casting the fixnum to a
string solved my problem but I'm wondering if this is a bug or it was a
bug and now it's working as intended or ...?

Choking code please.
matz.
Here's the code in question, I'm using REXML Document
doc = Document.new(entry.embed_code)
doc.root.each_element('//embed | //object'){ |elem|
elem.attributes['height'] = 140 #this is line 57, see error
below
elem.attributes['width'] = 170
}
The above code generated this error
NoMethodError (private method `gsub' called for 140:Fixnum):
c:/ruby/lib/ruby/1.8/rexml/text.rb:292:in `normalize'
c:/ruby/lib/ruby/1.8/rexml/element.rb:1085:in `='
/app/controllers/application.rb:57:in `resize_videos'
c:/ruby/lib/ruby/1.8/rexml/element.rb:891:in `each'
c:/ruby/lib/ruby/1.8/rexml/xpath.rb:53:in `each'
c:/ruby/lib/ruby/1.8/rexml/element.rb:891:in `each'
c:/ruby/lib/ruby/1.8/rexml/element.rb:393:in `each_element'
/app/controllers/application.rb:56:in `resize_videos'
To fix it, I changed it to
doc = Document.new(entry.embed_code)
doc.root.each_element('//embed | //object'){ |elem|
elem.attributes['height'] = 140.to_s
elem.attributes['width'] = 170.to_s
}
I'm hardly an expert on Ruby or REXML, so any insight is much
appreciated.

The following patch should work.

This is a change in the REXML code, if I have to make a change, I'm more
comfortable with changing my own code. Is this change a REXML bug fix or
simply a fix for my problem? I'm still trying to figure out if 1.8.6
introduced a bug of some kind whether it be in gsub or REXML.

gsub has no bug. This is a backport from 1.9 rexml.

Matz,
Thank you, thank you, thank you, I really mean it, can you tell =), for
clarifying this, I have been trying to figure out where the issue is and
now I know. I'll apply the patch in REXML.

FYI, I have committed the patch to the 1.8 HEAD.

Matz, thanks.
