Test Name: Big file in archive
|
|
Author: Josef Zila <jzila@redhat.com>
|
|
Location: CoreOS/zip/Functionality/stress-tests/big-file-in-archive/PURPOSE
|
|
|
|
Short Description:
|
|
Tests handling large files (2GB,3GB,4GB)
|
|
|
|
Long Description:
|
|
Test creates three files (2GB, 3GB and 4GB large) and attempts to archive each of them using zip. Then original files are deleted
|
|
and archives are unpacked, to check size of unpacked files. Current version of zip on all archs and distros in time of
|
|
writing(2.31-1) passes test. Note: 4GB file is too large for zip to handle, so it is not supposed to be successfully archived
|
|
or unpacked, test just checks for correct return codes.
|
|
|
|
|
|
how to run it:
|
|
python2 test_big_file_in_archive.py
|
|
|
|
TEST UPDATED (esakaiev)
|
|
------------------------
|
|
After rebase to zip-3.0-1 there is no 4GB limit. Patching the test accordingly.
