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
