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 --- doc/index.mdwn | 46 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 46 insertions(+) create mode 100644 doc/index.mdwn (limited to 'doc/index.mdwn') diff --git a/doc/index.mdwn b/doc/index.mdwn new file mode 100644 index 0000000..f880bc6 --- /dev/null +++ b/doc/index.mdwn @@ -0,0 +1,46 @@ +`git-repair` can repair various forms of damage to git repositories. + +It is a complement to `git fsck`, which finds problems, but does not fix +them. + +## download + + git clone git://git-repair.branchable.com/ git-repair + +## install + +This is a Haskell program, developed as a spinoff of +[git-annex](http://git-annex.branchable.com/). + +To build it, you will need to install the +[Haskell Platform](http://www.haskell.org/platform/). + +Then to install it: + + cabal update; cabal install git-repair --bindir=$HOME/bin + +## how it works + +`git-repair` starts by deleting all corrupt objects, and +retreiving all missing objects that it can from the remotes of the +repository. + +If that is not sufficient to fully recover the repository, it can also +reset branches back to commits before the corruption happened, delete +branches that are no longer available due to the lost data, and remove any +missing files from the index. It will only do this if run with the +`--force` option, since that rewrites history and throws out missing data. + +After running this command, you will probably want to run `git fsck` to +verify it fixed the repository. + +Note that fsck may still complain about objects referenced by the reflog, +or the stash, if they were unable to be recovered. This command does not +try to clean up either the reflog or the stash. + +Also note that the `--force` option never touches tags, even if they are no +longer usable due to missing data, so fack may also find problems with +tags. + +Since this command unpacks all packs in the repository, you may want to +run `git gc` afterwards. -- cgit v1.2.3
