2015-01-16tests: correct misuses of POSIXPERMLibravatar Junio C Hamano1-4/+13
POSIXPERM requires that a later call to stat(2) (hence "ls -l") faithfully reproduces what an earlier chmod(2) did. Some filesystems cannot satisify this. SANITY requires that a file or a directory is indeed accessible (or inaccessible) when its permission bits would say it ought to be accessible (or inaccessible). Running tests as root would lose this prerequisite for obvious reasons. Fix a few tests that misuse POSIXPERM. t0061-run-command.sh has two uses of POSIXPERM. - One checks that an attempt to execute a file that is marked as unexecutable results in a failure with EACCES; I do not think having root-ness or any other capability that busts the filesystem permission mode bits will make you run an unexecutable file, so this should be left as-is. The test does not have anything to do with SANITY. - The other one expects 'git nitfol' runs the alias when an alias.nitfol is defined and a directory on the PATH is marked as unreadable and unsearchable. I _think_ the test tries to reject the alternative expectation that we want to refuse to run the alias because it would break "no alias may mask a command" rule if a file 'git-nitfol' exists in the unreadable directory but we cannot even determine if that is the case. Under !SANITY that busts the permission bits, this test no longer checks that, so it must be protected with SANITY. t1509-root-worktree.sh expects to be run on a / that is writable by the user and sees if Git behaves "sensibly" when /.git is the repository to govern a worktree that is the whole filesystem, and also if Git behaves "sensibly" when / itself is a bare repository with refs, objects, and friends (I find the definition of "behaves sensibly" under these conditions hard to fathom, but it is a different matter). The implementation of the test is very much problematic. - It requires POSIXPERM, but it does not do chmod or checks modes in any way. - It runs "rm /*" and "rm -fr /refs /objects ..." in one of the tests, and also does "cd / && git init --bare". If done on a live system that takes advantages of the "feature" being tested, these obviously will clobber the system. But there is no guard against such a breakage. - It uses "test $UID = 0" to see rootness, which now should be spelled "! test_have_prereq NOT_ROOT" Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-10-13shell portability: no "export VAR=VAL"Libravatar Junio C Hamano1-14/+14
It is more portable to say "VAR=VAL && export VAR" instead. Noticed by Ævar. Signed-off-by: Junio C Hamano <gitster@pobox.com>
2010-06-25tests: Skip tests in a way that makes sense under TAPLibravatar Ævar Arnfjörð Bjarmason1-3/+3
SKIP messages are now part of the TAP plan. A TAP harness now knows why a particular test was skipped and can report that information. The non-TAP harness built into Git's test-lib did nothing special with these messages, and is unaffected by these changes.

2010-02-16Add test for using Git at root of file systemLibravatar Nguyễn Thái Ngọc Duy1-0/+249
This kind of test requires a throw-away root filesystem so that it can play on. If you have such a system, go ahead, "chmod 777 /" and run this test manually. Because this is a dangerous test, you are required to set an env variable, and not to use root to run it. Script prepare-root.sh may help you set up a chroot environment with Git test suite inside. You will need Linux, static linked busybox, rsync and root permission to use it. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
