You can back up a +git directory using clone, or just using cp, tar, or any other backup +mechanism. + +As a last resort, you can search for the corrupted objects and attempt +to replace them by hand. Back up your repository before attempting this +in case you corrupt things even more in the process. + +We'll assume that the problem is a single missing or corrupted blob, +which is sometimes a solveable problem. (Recovering missing trees and +especially commits is *much* harder). + +Before starting, verify that there is corruption, and figure out where +it is with gitlink:git-fsck[1]; this may be time-consuming. + +Assume the output looks like this: + +------------------------------------------------ +$ git-fsck --full +broken link from tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8 + to blob 4b9458b3786228369c63936db65827de3cc06200 +missing blob 4b9458b3786228369c63936db65827de3cc06200 +------------------------------------------------ + +(Typically there will be some "dangling object" messages too, but they +aren't interesting.) + +Now you know that blob 4b9458b3 is missing, and that the tree 2d9263c6 +points to it. If you could find just one copy of that missing blob +object, possibly in some other repository, you could move it into +.git/objects/4b/9458b3... and be done. Suppose you can't. You can +still examine the tree that pointed to it with gitlink:git-ls-tree[1], +which might output something like: + +------------------------------------------------ +$ git ls-tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8 +100644 blob 8d14531846b95bfa3564b58ccfb7913a034323b8 .gitignore +100644 blob ebf9bf84da0aab5ed944264a5db2a65fe3a3e883 .mailmap +100644 blob ca442d313d86dc67e0a2e5d584b465bd382cbf5c COPYING +... +100644 blob 4b9458b3786228369c63936db65827de3cc06200 myfile +... +------------------------------------------------ + +So now you know that the missing blob was the data for a file named +"myfile".

By default they point to git homepage; + in the past they pointed to git documentation at www.kernel.org. + * $projects_list_description_width + The width (in characters) of the projects list "Description" column. + Longer descriptions will be cut (trying to cut at word boundary); + full description is available as 'title' attribute (usually shown on + mouseover).
