fsck: HEAD is part of refs By default we looked at all refs but not HEAD. The only thing that made fsck not lose sight of commits that are only reachable from a detached HEAD was the reflog for the HEAD. This fixes it, with a new test. Signed-off-by: Junio C Hamano <gitster@pobox.com>

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 <file) = 0, for better debugging output when running tests with -v; - add a remove_object () helper and use it to replace broken object removal code that forgot about the fanout in .git/objects; - disable gc.auto, to avoid tripping up object removal if the number of objects ever reaches that threshold. - use test_when_finished to ensure cleanup tasks are run and succeed when tests fail; - add a new final test that no breakage or dangling objects was left behind. While at it, add a brief description to test_description of the history that is expected to persist between tests. Part of a campaign to clean up subshell usage in tests.

fsck: check loose objects from alternate object stores by default "git fsck" used to validate only loose objects that are local and nothing else by default. This is not just too little when a repository is borrowing objects from other object stores, but also caused the connectivity check to mistakenly declare loose objects borrowed from them to be missing. The rationale behind the default mode that validates only loose objects is because these objects are still young and more unlikely to have been pushed to other repositories yet. That holds for loose objects borrowed from alternate object stores as well. Signed-off-by: Junio C Hamano <gitster@pobox.com>

fsck: --no-dangling omits "dangling object" information The default output from "fsck" is often overwhelmed by informational message on dangling objects, especially if you do not repack often, and a real error can easily be buried. Add "--no-dangling" option to omit them, and update the user manual to demonstrate its use. Based on a patch by Clemens Buchacher, but reverted the part to change the default to --no-dangling, which is unsuitable for the first patch. The usual three-step procedure to break the backward compatibility over time needs to happen on top of this, if we were to go in that direction. Signed-off-by: Junio C Hamano <gitster@pobox.com>

fsck: report integer overflow in author timestamps When we check commit objects, we complain if commit->date is ULONG_MAX, which is an indication that we saw integer overflow when parsing it. However, we do not do any check at all for author lines, which also contain a timestamp. Let's actually check the timestamps on each ident line with strtoul. This catches both author and committer lines, and we can get rid of the now-redundant commit->date check. Note that like the existing check, we compare only against ULONG_MAX. Now that we are calling strtoul at the site of the check, we could be slightly more careful and also check that errno is set to ERANGE. However, this will make further refactoring in future patches a little harder, and it doesn't really matter in practice. For 32-bit systems, one would have to create a commit at the exact wrong second in 2038. But by the time we get close to that, all systems will hopefully have moved to 64-bit (and if they haven't, they have a real problem one second later). For 64-bit systems, by the time we get close to ULONG_MAX, all systems will hopefully have been consumed in the fiery wrath of our expanding Sun.

If X is checked first, fsck remembers X's type and then when it checks T, it notices that T records X as a wrong type (i.e. the complaint is about a broken tag T). If T is checked first, on the other hand, fsck remembers that we need to verify X is of the type tag records, and when it later checks X, it notices that X is of a wrong type (i.e. the complaint is about a broken object X). The important thing is that fsck notices such an error and diagnoses the issue on object X, but the test was expecting that we happen to check objects in the order to make us detect issues with tag T, not with object X. Remove this unwarranted assumption. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Test fsck a bit harder git-fsck, of all tools, has very few tests. This adds some more: * a corrupted object; * a branch pointing to a non-commit; * a tag pointing to a nonexistent object; * and a tag pointing to an object of a type other than what the tag itself claims. Only the first two are caught. At least the third probably should, too, but currently slips through.

Add regression tests for stricter tag fsck'ing The intent of the new test case is to catch general breakages in the fsck_tag() function, not so much to test it extensively, trying to strike the proper balance between thoroughness and speed. While it *would* have been nice to test the code path where fsck_object() encounters an invalid tag object, this is not possible using git fsck: tag objects are parsed already before fsck'ing (and the parser already fails upon such objects). Even worse: we would not even be able write out invalid tag objects because git hash-object parses those objects, too, unless we resorted to really ugly hacks such as using something like this in the unit tests (essentially depending on Perl *and* Compress::Zlib): hash_invalid_object () { contents="$(printf '%s %d\0%s' "$1" ${#2} "$2")" && sha1=$(echo "$contents" | test-sha1) && suffix=${sha1#??} && mkdir -p .git/objects/${sha1%$suffix} && echo "$contents" | perl -MCompress::Zlib -e 'undef $/; print compress(<>)' \ > .git/objects/${sha1%$suffix}/$suffix && echo $sha1 } Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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 <file) = 0, for better debugging output when running tests with -v; - add a remove_object () helper and use it to replace broken object removal code that forgot about the fanout in .git/objects; - disable gc.auto, to avoid tripping up object removal if the number of objects ever reaches that threshold. - use test_when_finished to ensure cleanup tasks are run and succeed when tests fail; - add a new final test that no breakage or dangling objects was left behind. While at it, add a brief description to test_description of the history that is expected to persist between tests. Part of a campaign to clean up subshell usage in tests.

fsck: detect null sha1 in tree entries Short of somebody happening to beat the 1 in 2^160 odds of actually generating content that hashes to the null sha1, we should never see this value in a tree entry. So let's have fsck warn if it it seen. As in the previous commit, we test both blob and submodule entries to future-proof the test suite against the implementation depending on connectivity to notice the error.

fsck: warn about '.' and '..' in trees A tree with meta-paths like '.' or '..' does not work well with git; the index will refuse to load it or check it out to the filesystem (and even if we did not have that safety, it would look like we were overwriting an untracked directory). For the same reason, it is difficult to create such a tree with regular git. Let's warn about these dubious entries during fsck, just in case somebody has created a bogus tree (and this also lets us prevent them from propagating when transfer.fsckObjects is set).

fsck: warn about ".git" in trees Having a ".git" entry inside a tree can cause confusing results on checkout. At the top-level, you could not checkout such a tree, as it would complain about overwriting the real ".git" directory. In a subdirectory, you might check it out, but performing operations in the subdirectory would confusingly consider the in-tree ".git" directory as the repository. The regular git tools already make it hard to accidentally add such an entry to a tree, and do not allow such entries to enter the index at all. Teaching fsck about it provides an additional safety check, and let's us avoid propagating any such bogosity when transfer.fsckObjects is on.
