25 # @summary Check support for jar file members with sizes > 2GB
26 # @author Martin Buchholz
27 #
28 # @build FileBuilder
29 # @run shell 3GBZipFiles.sh 9986
30 # @ignore runs for hours and eats up 7 Gigabytes of disk space
31 # @run shell/timeout=604800 3GBZipFiles.sh 3141592653
32
33 # Command-line usage:
34 # javac FileBuilder.java && sh 3GBZipFiles.sh /path/to/jdk filesize
35
36 # -------------------------------------------------------------------
37 # Testing strategy: We want to test for size limits on the Jar file
38 # itself, as well as on the compressed and uncompressed sizes of the
39 # files stored therein. All of these limits should be 4GB and should
40 # be tested in the 2GB-4GB range. We also want to check that it is
41 # possible to store more than 6GB of actual data in a zip file, if we
42 # have two files of size 3GB which compress nicely. We also want to
43 # test both the "STORED" and "DEFLATED" compression methods.
