Zlib::BufError

Ruby Apps Radiant CMS
1

I’m having a problem upgrading from 0.6.1 to 0.6.2 on my local (Windows
XP) test machine. I have tried this on a couple of Windows machines and
each time I get a (Zlib::BufError) buffer error.

On my local machine I have updated Ruby to version 1.8.6 and have
updated Ruby Gems to 0.9.4. I have also tried a clean install of Ruby,
Gems and Radiant on a newly formatted machine, but again get the buffer
error.

Any help would be appreciated.

Thanks

Sharon

There was some discussion of this problem on the Capistrano mailing
list too. Apparently, it’s a bug in RubyGems. Here’s the fix, from
Jamis:

P.S. If you are on a Windows machine, and you get Zlib errors trying
to install the Capistrano gem, try this. Find the rubygems/package.rb
file (wherever it happens to be in your Ruby installation), open it
up, and find the zipped_stream method. Then, replace it, wholesale,
with the following:

def zipped_stream(entry)
entry.read(10) # skip the gzip header
zis = Zlib::Inflate.new(-Zlib::MAX_WBITS)
is = StringIO.new(zis.inflate(entry.read))
ensure
zis.finish if zis
end

Cheers,
