Issue #8340 has been updated by Thilo.Opaterny (Thilo Opaterny).


Another try to fix this is to add

    def kind_of?( arg )
        super( arg ) || __getobj__.kind_of?( arg )
    end

to c:\win\Ruby200x64\lib\ruby\gems\2.0.0\gems\rubyzip-0.9.9\lib\zip\zip_streamable_stream.rb

Bug #8340: rubyzip does not save time of zipped files
https://bugs.ruby-lang.org/issues/8340#change-38961

Author: Thilo.Opaterny (Thilo Opaterny)
Status: Third Party's Issue
Priority: Normal
Assignee: 
Category: 
Target version: 
ruby -v: ruby 2.0.0p0 (2013-02-24) [x64-mingw32]      rubyzip (0.9.9)
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


I wrote a little test
----------------------
require 'zip/zip'

zipName = "test.zip"
zipFile = Zip::ZipFile.open( zipName, Zip::ZipFile::CREATE )

file = File.open( "save.rb", "rb")
puts time = Zip::DOSTime.at( file.mtime )
zipEntry = Zip::ZipEntry.new( zipName, file.path, "", "", 0, 0, Zip::ZipEntry::DEFLATED, 0, time ) // I want to keep the time
outputStream = zipFile.get_output_stream( zipEntry );
outputStream << file.read
file.close
outputStream.close

zipFile.close()

Zip::ZipFile.foreach( zipName ){ |zipEntry|
    p zipEntry.name
    p zipEntry.time
}
------------------

it returns

2013-04-08 21:05:20 +0200
"save.rb"
2013-04-27 22:11:36 +0200

obvious it does not keep the time.


I can fix the problem if I change line 34 of c:\win\Ruby200x64\lib\ruby\gems\2.0.0\gems\rubyzip-0.9.9\lib\zip\zip_output_stream.rb 
into       if entryname.kind_of?(ZipEntry) or entryname.kind_of?( ZipStreamableStream )
but I feel that this is not the right way to do it, because there are at least 4 other kind_of?(ZipEntry) in that lib

c:\win\Ruby200x64\lib\ruby\gems\2.0.0\gems\rubyzip-0.9.9\lib\zip\zip_streamable_stream.rb 
tells mee that ZipStreamableStream < DelegateClass(ZipEntry)
so I think the problem should be fixed in there. But how?
