#Gitup git2 vs update

This allows individuals to rotate their SSH keys by keeping track of when each key was valid without invalidating any objects previously signed using an older key. Git 2.35 lets you take advantage of OpenSSH’s valid-before and valid-after directives by making sure that the object you’re verifying was signed using a signature that was valid when it was created. You could store both keys, but that would mean that you would accept new objects signed with the old key.

#Gitup git2 vs update

What do you do? You could update their entry in the allowed signers file to point at their new key, but that would make it impossible to validate objects signed with the older key. Now suppose that one of your collaborators rotates their key. To track which SSH keys you trust, you use the allowed signers file to store the identities and public keys of signers you trust.

Suppose you use SSH keys to sign objects in a project you work on. This release includes a couple of new additions to SSH signing. In our last post, we talked about SSH signing: a new feature in Git that allows you to use the SSH key you likely already have in order to sign certain kinds of objects in Git. Which is much cleaner than this alternative way to combine git log and git describe: $ git log -8 -format='%H' | xargs git describe -exclude='*-rc*' -abbrev=13

Here’s a goofy example that gives me the git describe output for the last 8 commits in my copy of git.git, using only non-release-candidate tags, and uses 13 characters to abbreviate their hashes: $ git log -8 -format='%(describe:exclude=*-rc*,abbrev=13)' You can try these out with %(describe:tags=) and %(describe:abbrev=), respectively. You can now control whether to use lightweight tags, and how many hexadecimal characters to use when abbreviating an object identifier. In 2.35, Git includes a couple of new ways to tweak the output of git describe. When it was first released, you could pass additional options down through the %(describe) specifier, like matching or excluding certain tags by writing -format=%(describe:match=,exclude=). This made it possible to include the output of git describe alongside the output of git log. In our blog post covering Git 2.33, we talked about a new -format specifier called %(describe). These can be handy when sprucing up your terminal, but they are especially useful for making it easier to script around the output of git log. Git log has a rich set of -format options that you can use to customize the output of git log. Then, when you’re ready, you can recover your changes (with git stash pop) and keep working. You can think of it like git commit (which only writes staged changes), but instead of creating a new commit, it writes a new entry to the stash. Git stash‘s new -staged mode makes it easy to stash away what you already have in the staging area, and nothing else. But what if you already did that via an earlier git add -p? Perhaps when you started, you thought you were ready to commit something, but by the time you finished staging everything, you realized that you actually needed to stash it all away and work on something else. But what if you only want to store part of your changes in the stash? You could use git stash -p and interactively select hunks to stash or keep. Using git stash this way makes it really easy to store all accumulated changes for later use. To do this, we use the git stash tool, which stores away any changes to files tracked in your Git repository. When working on a complicated change, it can be useful to temporarily discard parts of your work in order to deal with them separately.To celebrate this most recent release, here’s GitHub’s look at some of the most interesting features and changes introduced since last time. We last caught up with you on the latest in Git back when 2.34 was released.

The open source Git project just released Git 2.35, with features and bug fixes from over 93 contributors, 35 of them new.
