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