From 7e592e1d6ed5e0b25b37215da7558c6324688d6f Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Fri, 22 Nov 2013 11:16:03 -0400 Subject: git-repair (1.20131122) unstable; urgency=low * Added test mode, which can be used to randomly corrupt test repositories, in reproducible ways, which allows easy corruption-driven-development. * Improve repair code in the case where the index file is corrupt, and this hides other problems. * Write a dummy .git/HEAD if the file is missing or corrupt, as git otherwise will not treat the repository as a git repo. * Improve fsck code to find badly corrupted objects that crash git fsck before it can complain about them. * Fixed crashes on bad file encodings. * Can now run 10000 tests (git-repair --test -n 10000 --force) with 0 failures. # imported from the archive --- Git/Objects.hs | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) create mode 100644 Git/Objects.hs (limited to 'Git/Objects.hs') diff --git a/Git/Objects.hs b/Git/Objects.hs new file mode 100644 index 0000000..d9d2c67 --- /dev/null +++ b/Git/Objects.hs @@ -0,0 +1,35 @@ +{- .git/objects + - + - Copyright 2013 Joey Hess + - + - Licensed under the GNU GPL version 3 or higher. + -} + +module Git.Objects where + +import Common +import Git +import Git.Sha + +objectsDir :: Repo -> FilePath +objectsDir r = localGitDir r "objects" + +packDir :: Repo -> FilePath +packDir r = objectsDir r "pack" + +packIdxFile :: FilePath -> FilePath +packIdxFile = flip replaceExtension "idx" + +listPackFiles :: Repo -> IO [FilePath] +listPackFiles r = filter (".pack" `isSuffixOf`) + <$> catchDefaultIO [] (dirContents $ packDir r) + +listLooseObjectShas :: Repo -> IO [Sha] +listLooseObjectShas r = catchDefaultIO [] $ + mapMaybe (extractSha . concat . reverse . take 2 . reverse . splitDirectories) + <$> dirContentsRecursiveSkipping (== "pack") (objectsDir r) + +looseObjectFile :: Repo -> Sha -> FilePath +looseObjectFile r sha = objectsDir r prefix rest + where + (prefix, rest) = splitAt 2 (show sha) -- cgit v1.2.3
