Content
If you read the bug report it explains how to generate a testcase (i.e. append any data to the end of a zip archive) Here it is as a step by step process 1. simply take any working zip and call it testcase.zip 2. do the following: echo "\r\n" >> testcase.zip If you run "unzip -t" on testcase.zip it will pass with flying colors and will properly unzip on every piece of zip software I have tried. However if you try to use python to copy the zip archive to another zip archive python ./zipfix.py testcase.zip junk.zip Error Occurred File is not a zip file All because of the appended carriage return / linefeed at the end.
