From dbedf8bf42f63847b096aeb7d6b96cf3a2233b7a Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Mon, 6 Sep 2010 20:47:07 -0500 Subject: [PATCH] t1450 (fsck): remove dangling objects The fsck test is generally careful to remove the corrupt objects it inserts, but dangling objects are left behind due to some typos and omissions. It is better to clean up more completely, to simplify the addition of later tests. So: - guard setup and cleanup with test_expect_success to catch typos and errors; - check both stdout and stderr when checking for empty fsck output; - use test_cmp empty file in place of test $(wc -l Signed-off-by: Jonathan Nieder Signed-off-by: Junio C Hamano --- t/t1450-fsck.sh | 140 ++++++++++++++++++++++++++++-------------------- 1 file changed, 82 insertions(+), 58 deletions(-) diff --git a/t/t1450-fsck.sh b/t/t1450-fsck.sh index 759cf12e1..1be415e33 100755 --- a/t/t1450-fsck.sh +++ b/t/t1450-fsck.sh @@ -1,21 +1,23 @@ #!/bin/sh -test_description='git fsck random collection of tests' +test_description='git fsck random collection of tests + +* (HEAD) B +* (master) A +' . ./test-lib.sh test_expect_success setup ' + git config gc.auto 0 && git config i18n.commitencoding ISO-8859-1 && test_commit A fileA one && git config --unset i18n.commitencoding && git checkout HEAD^0 && test_commit B fileB two && git tag -d A B && - git reflog expire --expire=now --all -' - -test_expect_success 'HEAD is part of refs' ' - test 0 = $(git fsck | wc -l) + git reflog expire --expire=now --all && + >empty ' test_expect_success 'loose objects borrowed from alternate are not missing' ' @@ -25,110 +27,132 @@ test_expect_success 'loose objects borrowed from alternate are not missing' ' git init && echo ../../../.git/objects >.git/objects/info/alternates && test_commit C fileC one && - git fsck >out && - ! grep "missing blob" out - ) + git fsck >../out 2>&1 + ) && + { + grep -v dangling out >actual || + : + } && + test_cmp empty actual ' -test_expect_success 'valid objects appear valid' ' - { git fsck 2>out; true; } && - ! grep error out && - ! grep fatal out +test_expect_success 'HEAD is part of refs, valid objects appear valid' ' + git fsck >actual 2>&1 && + test_cmp empty actual ' # Corruption tests follow.
