* fsck: warn about ".git" in treesJeff King2012-11-28
| | | | | | | | | | | | | | | | | | | 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.

* fsck: warn about '.' and '..' in treesJeff King2012-11-28
| | | | | | | | | | | | | | | | | 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).

|\ | | | | | | | | | | | | | | | | | | | | "git diff" had a confusion between taking data from a path in the working tree and taking data from an object that happens to have name 0{40} recorded in a tree. * jk/maint-null-in-trees: fsck: detect null sha1 in tree entries do not write null sha1s to on-disk index diff: do not use null sha1 as a sentinel value
| * fsck: detect null sha1 in tree entriesJeff King2012-07-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: improve committer/author checkDmitry Ivankov2011-08-11
| | | | | | | | | | | | | | | | | | | | fsck allows a name with > character in it like "name> <email>". Also for "name email>" fsck says "missing space before email". More precisely, it seeks for a first '<', checks that ' ' preceeds it. Then seeks to '<' or '>' and checks that it is the '>'. Missing space is reported if either '<' is not found or it's not preceeded with ' '. Change it to following. Seek to '<' or '>', check that it is '<' and is preceeded with ' '. Seek to '<' or '>' and check that it is '>'. So now "name> <email>" is rejected as "bad name". More strict name check is the only change in what is accepted. Report 'missing space' only if '<' is found and is not preceeded with a space. Signed-off-by: Dmitry Ivankov <divanorama@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

* | strbuf: add strbuf_vaddfJeff King2011-02-26
|/ | | | | | | | | | | | | | | | In a variable-args function, the code for writing into a strbuf is non-trivial. We ended up cutting and pasting it in several places because there was no vprintf-style function for strbufs (which in turn was held up by a lack of va_copy). Now that we have a fallback va_copy, we can add strbuf_vaddf, the strbuf equivalent of vsprintf. And we can clean up the cut and paste mess.

* fsck: fix bogus commit header checkJonathan Nieder2010-05-28
| | | | | | | | | | | | | | | | | | | | | | | | daae1922 (fsck: check ident lines in commit objects, 2010-04-24) taught fsck to expect commit objects to have the form tree <object name> <parents> author <valid ident string> committer <valid ident string> log message The check is overly strict: for example, it errors out with the message “expected blank line” for perfectly valid commits with an "encoding ISO-8859-1" line. Later it might make sense to teach fsck about the rest of the header and warn about unrecognized header lines, but for simplicity, let’s accept arbitrary trailing lines for now.

* Allow the Unix epoch to be a valid commit dateEric Wong2009-07-06
| | | | | | | | | | | | | | It is common practice to use the Unix epoch as a fallback date when a suitable date is not available. This is true of git svn and possibly other importing tools that import non-git history into git. Instead of clobbering established strtoul() error reporting semantics with our own, preserve the strtoul() error value of ULONG_MAX for fsck.c to handle.

* fsck.c: fix bogus "empty tree" checkJunio C Hamano2008-03-05
| | | | | | | | | | | | | | | | | | | | | | ba002f3 (builtin-fsck: move common object checking code to fsck.c) did more than what it claimed to. Most notably, it wrongly made an empty tree object an error by pretending to only move code from fsck_tree() in builtin-fsck.c to fsck_tree() in fsck.c, but in fact adding a bogus check to barf on an empty tree. An empty tree object is _unusual_. Recent porcelains try reasonably hard not to let the user create a commit that contains such a tree. Perhaps warning about them in git-fsck may have some merit. HOWEVER. Being unusual and being errorneous are two quite different things. This is especially true now we seem to use the same fsck_$object() code in places other than git-fsck itself. For example, receive-pack should not reject unusual objects, even if it would be a good idea to tighten it to reject incorrect ones. Signed-off-by: Junio C Hamano <gitster@pobox.com>
