Deduplicate Git forks on a server

问题 Is there a way to hard-link all the duplicate objects in a folder containing multiple Git repositories? Explanation: I am hosting a Git server on my company server (Linux machine). The idea is to have a main canonical repository, to which every user doesn't have push access to, but every user forks the canonical repository (clones the canonical to the user's home directory, thereby creating hard-links actually). /canonical/Repo /Dev1/Repo (objects Hard-linked to /canonical/Repo to when

Soft link in Mercurial

问题 Is there some equivalent in Mercurial to NIX soft- or hard- links to directories or files. Basically that a file (or directory) is linked to a file "somewhere else" and follows the version of that location (Unlike a regular branch I think, where one would have to merge) 回答1: Mercurial versions soft links that are internal to the repository just great. It'll detect them, record them, and create them for you. Is there a specific use case you're looking for? The closest thing to an link that

Git and hard links

由 可紊 提交于 2019-11-27 03:09:07
Considering that Git does not recognize symbolic links that point outside of the repository, is there any problem using hard links? Could Git break them? Can you please point me to detailed information? Jakub Narębski The 'tree' object, representing directories in Git, stores file name and (subset of) permissions. It doesn't store inode number (or other kind of file id). Therefore hard links cannot be represented in git , at least not without third party tools such as metastore or git-cache-meta (and I am not sure if it is possible even with those tools). Git tries to not touch files that it

What is the difference between a symbolic link and a hard link?

Recently I was asked this during a job interview. I was honest and said I knew how a symbolic link behaves and how to create one, but do not understand the use of a hard link and how it differs from a symbolic one. Underneath the file system files are represented by inodes (or is it multiple inodes not sure) A file in the file system is basically a link to an inode. A hard link then just creates another file with a link to the same underlying inode. When you delete a file it removes one link to the underlying inode. The inode is only deleted (or deletable/over-writable) when all links to the
