Unknown problem with ZLib::Inflate
----------------------------------
Key: JRUBY-1424
URL: http://jira.codehaus.org/browse/JRUBY-1424
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: java 1.5.0_07 (Apple Computer, Inc.)
macos 10.4.10
Reporter: Travis Tilley
Attachments: rubyzip-test_extract-data
The rubyzip ZipFileExtract.test_extract test fails with a stack trace on JRuby
1.0.1 and trunk (oct12, 2007).
The Exception is:
Exception in thread "main" java.util.zip.DataFormatException: unknown
compression method
The compression method should be:
compression method is ZipEntry::DEFLATED
To reproduce:
Zlib::Inflate.inflate(File.new('rubyzip-test_extract-data').read)
Full rubyzip test output and trace:
in test_extract before ZipFile.open(5entry_copy.zip)
before zf.extract(data/generated/longBinary.bin, extEntry)
in ZipInputStream.open_entry, before ZipEntry.read_local_entry
compression method is ZipEntry::DEFLATED
in Zip::Inflater.initialize
inputStream class: File
inputStream: #<File:5entry_copy.zip>
in ZipInputStream.sysread
numberOfBytes = 32768
buf = ""
buf class = String
decompressor class = Zip::Inflater
before Zip::Inflater.sysread(numberOfBytes, buf)
in Inflater.sysread
before while loop
before internal_produce_input(buf)
@zlibInflater class: Zlib::Inflate
@zlibInflater: #<Zlib::Inflate:0x68632b>
@inputStream class: File
@inputStream: #<File:5entry_copy.zip>
buf class: String
Decompressor::CHUNK_SIZE -> 32768
before data = @inputStream.read(Decompressor::CHUNK_SIZE, buf)
writing the contents of data to file 'rubyzip-test_extract-data'
before @zlibInflater.inflate(data)
Exception in thread "main" java.util.zip.DataFormatException: unknown
