Can you please provide more information:

• What platform are you on? (ruby -v)
• What did you do? (Some code to reproduce the error)
• What version of ruby-filemagic are you using? (FileMagic::VERSION and FileMagic::MAGIC_VERSION)

[NVD-R]

1. ruby 1.9.3p484 (2013-11-22 revision 43786)

2. `def self.verifier @verifier ||= ActiveSupport::MessageVerifier.new(Config[:verifier_key]) end

   def self.text?(filename) begin fm = FileMagic.new(FileMagic::MAGIC_MIME) fm.file(filename) =~ /^text\// ensure fm.close end end

   def self.binary?(filename) !text?(filename) end`

3. 'ruby-filemagic', '0.7.1'

I cannot reproduce the error, but I'm almost certain this has nothing to do with ruby-filemagic, anyway. What does file --mime <your-long-file-name> say? (You might need to install the file utility first.)

file: text/plain; charset=us-ascii

[blackwinter]

Can you try File.open(filename) { |f| fm.fd(f) } instead of fm.file(filename)?

i use that code but not work !!! does exist any limitation for filename length in FileMagic?

i use that code but not work !!!

Please post the exact error message and backtrace.

does exist any limitation for filename length in FileMagic?

No, there's not. My suspicion was that libmagic had a limit; but seeing as the file command worked, we can probably rule that out. [EDIT: The exception is raised here, so the error definitely originates from inside libmagic.]

• What OS and file system are you running on?
• Which version(s) of libmagic are you using? (FileMagic::MAGIC_VERSION and file -v)
