DESCRIPTION ----------- -Verifies the connectivity and validity of the objects in the database. - -OPTIONS -------- -<object>:: - An object to treat as the head of an unreachability trace. -+ -If no objects are given, git-fsck-objects defaults to using the -index file and all SHA1 references in .git/refs/* as heads. - ---unreachable:: - Print out objects that exist but that aren't readable from any - of the reference nodes. - ---root:: - Report root nodes. - ---tags:: - Report tags. - ---cache:: - Consider any object recorded in the index also as a head node for - an unreachability trace. - ---full:: - Check not just objects in GIT_OBJECT_DIRECTORY - ($GIT_DIR/objects), but also the ones found in alternate - object pools listed in GIT_ALTERNATE_OBJECT_DIRECTORIES - or $GIT_DIR/objects/info/alternates, - and in packed git archives found in $GIT_DIR/objects/pack - and corresponding pack subdirectories in alternate - object pools. - ---strict:: - Enable more strict checking, namely to catch a file mode - recorded with g+w bit set, which was created by older - versions of git. Existing repositories, including the - Linux kernel, git itself, and sparse repository have old - objects that triggers this check, but it is recommended - to check new projects with this flag. - -It tests SHA1 and general object sanity, and it does full tracking of -the resulting reachability and everything else. It prints out any -corruption it finds (missing or bad objects), and if you use the -'--unreachable' flag it will also print out objects that exist but -that aren't readable from any of the specified head nodes. - -So for example - - git-fsck-objects --unreachable HEAD $(cat .git/refs/heads/*) - -will do quite a _lot_ of verification on the tree. There are a few -extra validity tests to be added (make sure that tree objects are -sorted properly etc), but on the whole if "git-fsck-objects" is happy, you -do have a valid tree. - -Any corrupt objects you will have to find in backups or other archives -(i.e., you can just remove them and do an "rsync" with some other site in -the hopes that somebody else has the object you have corrupted). - -Of course, "valid tree" doesn't mean that it wasn't generated by some -evil person, and the end result might be crap. git is a revision -tracking system, not a quality assurance system ;) - -Extracted Diagnostics ---------------------- - -expect dangling commits - potential heads - due to lack of head information:: - You haven't specified any nodes as heads so it won't be - possible to differentiate between un-parented commits and - root nodes. - -missing sha1 directory '<dir>':: - The directory holding the sha1 objects is missing. - -unreachable <type> <object>:: - The <type> object <object>, isn't actually referred to directly - or indirectly in any of the trees or commits seen. This can - mean that there's another root node that you're not specifying - or that the tree is corrupt. If you haven't missed a root node - then you might as well delete unreachable nodes since they - can't be used. - -missing <type> <object>:: - The <type> object <object>, is referred to but isn't present in - the database. - -dangling <type> <object>:: - The <type> object <object>, is present in the database but never - 'directly' used. A dangling commit could be a root node. - -warning: git-fsck-objects: tree <tree> has full pathnames in it:: - And it shouldn't... - -sha1 mismatch <object>:: - The database has an object who's sha1 doesn't match the - database value. - This indicates a serious data integrity problem. - -Environment Variables ---------------------- - -GIT_OBJECT_DIRECTORY:: - used to specify the object database root (usually $GIT_DIR/objects) - -GIT_INDEX_FILE:: - used to specify the index file of the index - -GIT_ALTERNATE_OBJECT_DIRECTORIES:: - used to specify additional object database roots (usually unset) - -Author ------- -Written by Linus Torvalds <torvalds@osdl.org> - -Documentation --------------- -Documentation by David Greaves, Junio C Hamano and the git-list <git@vger.kernel.org>. - -GIT ---- -Part of the gitlink:git[7] suite +This is a synonym for gitlink:git-fsck[1].
