Weird progress bar failure on unrelated spec


#1

Hi

Before I try to recreate this, does anyone know what generally causes
this in a progress spec run?

…/opt/local/lib/ruby/gems/1.8/gems/
rspec-1.1.12/lib/spec/runner/formatter/progress_bar_formatter.rb:25:in
flush': Bad file descriptor (Errno::EBADF) from /opt/local/lib/ruby/gems/1.8/gems/rspec-1.1.12/lib/spec/runner/ formatter/progress_bar_formatter.rb:25:instart_dump’

from spec/followme/content/bbc_page_spec.rb:106

(Line 106 reads ‘describe LowGraphicsBBCPage do’)

The problem is that the file spec/followme/content/bbc_page_spec.rb is
NOT the source of the error, it’s actually caused by this in another
file:

 class RssReader
   class RssReaderError < StandardError; end

   def initialize(uri)
     @uri = uri
   end

   def rss
     rss =
       begin
         ::RSS::Parser.parse(@uri.read, false)
       rescue OpenURI::HTTPError, Errno::ECONNREFUSED => error
         # For some bizarre reason this next line breaks breaks

the specs
# FollowMe.logger.warn(“Error reading RSS”)
FollowMe.logger.warn(error)
raise RssReaderError.new(error.message)
end
raise RssReaderError.new(“No RSS in feed”) unless rss
rss
end
end

FollowMe.logger is a mock during the specs of RssReader, but RssReader
is not referenced in spec/followme/content/bbc_page_spec.rb at all.
Stranger, the second of the two log calls does not cause an error.

Anyone got any pointers that could help me figure this one out?

Cheers
Ashley

Just as an addendum to that, it also exhibits freezing behaviour on
one of the specs (presumably the same) with just the one line in
place. (It just hangs indefinitely during the progress output.)

Don’t expect anyone will be able to figure this out without seeing all
the code, so I’m hoping someone can tell me where to look…
