1This directory contains scripts for testing GNU tar using 2star "test archives". The archives themselves can be obtained 3from http://download.berlios.de/pub/star/testscripts. 4 5The tests are ignored unless environment variable STAR_TESTSCRIPTS 6is set and points to the directory where the test archives reside. 7Sample usage: 8 9 make STAR_TESTSCRIPTS=testdir check 10or 11 make TESTS_ENVIRONMENT='STAR_TESTSCRIPTS=testdir' check 12 13The file `quicktest.sh' is a separate test. It is never executed 14within `make check' command, you will need to run it manually. 15Please, carefully read section `quicktest.sh' below before running 16it. 17 18Following is a short description of the tests: 19 20* gtarfail.at and gtarfail2.at 21 22These tests require gtarfile.tar and gtarfile2.tar, respectively. 23These files are POSIX compliant tar archives that were not accepted 24by previous versions of GNU tar. 25 26* multi-fail.at 27 28Requires gnu-multi-fail-volume1.gtar and gnu-multi-fail-volume2.gtar. 29These are two parts of a multi-volume archive that previous versions 30of tar refused to read (at least, without -B option). 31 32* ustar-big-2g.at 33 34Requires ustar-big-2g.tar.bz2. It is a tar archive containing a file with 35the largest size that a historic tar implementation is able to understand. 36 37* ustar-big-8g.at 38 39Requires ustar-big-8g.tar.bz2. This is a test for reading an archive containing 40files with the largest size that may be used with ustar (POSIX.1-1990) 41format. 42 43* pax-big-10g.at 44 45Requires pax-big-10g.tar.bz2. It tests handling pax (POSIX.1-2001) archves 46containing very large files (in this case -- 10 GB). 47 48* quicktest.sh 49 50This is a test for compliance to POSIX.1-1990 tar specification. It 51requires two files: ustar-all-quicktest.tar and quicktest.filelist, 52(they usually reside in star/tartest directory), and `tartest' program 53(also part of star distribution). The test must be run only with root 54privileges, so it is a good idea to test contents of 55ustar-all-quicktest.tar before running it. 56 57If `tartest' is not in your PATH, use TARTEST variable to specify its 58full file name. You may pass both STAR_TESTSCRIPTS and TARTEST 59variables as command line arguments to quicktest.sh, as shown in 60the example below: 61 62 ./quicktest.sh STAR_TESTSCRIPTS=testdir TARTEST=/path/to/tartest 63 64 65Local variables: 66mode: outline 67paragraph-separate: "[ ]*$" 68end: 69
