    Git-ing a bit stale?

    RHEL/CentOS 7 is starting to feel a somewhat dated, but it still has over 2½ years before it reaches the end of its support lifetime that Red Hat has set for the end of June 2024.

    One component that is far enough outdated to cause serious annoyance is Git.

    Git is by far the most-used version control system in the world. It popularized the distributed model of tracking changes to source code files and greatly simplified collaboration by multiple developers. It is open source and free software and is used by most public and many internal software projects, and also by solo developers. IDEs such as VS Code and IntelliJ idea integrate with it. SaaS code hosting providers GitHub, GitLab, Bitbucket, and others are built around it. We have been using and advocating Git since 2007 — see our blog posts about Git for a variety of helpful articles.

    CentOS/RHEL 7 includes Git version 1.8.3, which was released in May 2013. There have been 2 major, 36 minor, and 216 patch releases of Git in the 8½ years between then and the current version 2.34.1!

    The makers of CentOS/RHEL have good reasons to stick with versions they shipped with for the lifetime of the operating system: compatibility, stability, predictability. They only want to release updates that are entirely compatible, mostly for bugfixes and security updates.

    Using a newer version will likely have some differences, but for software primarily used interactively by humans who can adapt to change, this is often worth the tradeoff of more features vs. occasional unexpected change.

    We help you freshen up

    To relieve the pain of aging software, we here at End Point Dev package up newer Git versions for RHEL 7 as needed for ourselves and our clients. You can use it too! Our current packaged version as of today is the latest Git, version 2.34.1, which was released on 24 November 2021.

    Why not just build the latest version from source? That works well on a single developer workstation if you don’t mind staying abreast of each new Git release on your own, and doing a bit of work to build them.

    We recommend using packages specific to your OS because it is faster, easier, and fits well with automation tools such as Ansible, Salt, Chef, and Puppet. And when you configure a Yum repository that includes ongoing package updates, the updates are automatically applied to all your systems as part of your routine OS maintenance.

    Here are instructions showing how you can install the latest Git package we built, on CentOS/RHEL 7 systems.

    Check your version of git

    First, see what version you have installed:

    $ git --version
    git version

    Now see where it is installed:

    $ which git

    If you have git installed somewhere else, such as /usr/local/bin/git, it was probably built from source and installed there, and you should consider deleting that other installation before you install this new packaged one.

    To make sure it was installed from an RPM using yum:

    $ rpm -qi git
    Name        : git
    Version     :
    Release     : 23.el7_8
    Source RPM  : git-
    Build Date  : Thu 28 May 2020 08:37:56 PM UTC
    Build Host  : x86-02.bsys.centos.org
    Packager    : CentOS BuildSystem <http://bugs.centos.org>
    Vendor      : CentOS

    (I omitted a few uninteresting lines from that output so we can focus on the essentials.)

    If instead of the above you see this from rpm and/or don’t have git installed at all:

    $ rpm -qi git
    package git is not installed
    $ which git
    /usr/bin/which: no git in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)

    That’s fine. In that case you will just be installing Git on this system for the first time.

    Add the End Point Yum repository

    Now install the End Point package repository Yum repo package:

    $ sudo yum install https://packages.endpointdev.com/rhel/7/os/x86_64/endpoint-repo.x86_64.rpm

    That adds two important files to your system:

    Yum repo config file

    The first is /etc/yum.repos.d/endpoint.repo which is configuration for yum, an extension to its main /etc/yum.conf configuration file. Here is where we point your Yum setup to our packages.endpointdev.com repository to look for packages in the future.

    GnuPG key

    The second is /etc/pki/rpm-gpg/RPM-GPG-KEY-endpoint-7 which is the PGP/GnuPG public key matching the secret key we use to sign packages in our repository, so your yum can verify the packages have not been corrupted, either accidentally during transmission, or intentionally by Bad Folks.

    Install or upgrade git

    Now installing or upgrading to the new version of Git is as simple as:

    $ sudo yum install git

    You can use yum upgrade git if you already have it installed, but yum install git works in either case.

    You should see output similar to this:

    Is this ok [y/d/N]: y

    If you don’t see the new git version available, you may need to clear your Yum caches with:

    $ sudo yum clean all

    In the install/upgrade output above from yum, notice the question: “Is this ok”? As long as what you see is similar to the above, everything should be fine. But investigate further before proceeding if it proposed any unexpected package upgrades or removals.

    If you agree to continue, you’ll see something like:

    Dependency Updated:
      perl-Git.noarch 0:2.34.1-1.ep7

    Now check again which version of git is installed, and what the RPM database contains:

    $ git --version
    git version 2.34.1
    $ rpm -qi git
    Name        : git
    Version     : 2.34.1
    Release     : 1.ep7
    Architecture: x86_64
    Source RPM  : git-2.34.1-1.ep7.src.rpm
    Build Date  : Thu 09 Dec 2021 01:15:52 AM UTC
    Build Host  : rhel7-build64.epinfra.net
    Packager    : End Point Hosting Team <hosting@endpointdev.com>
    Vendor      : End Point Dev - https://packages.endpointdev.com/

    (Again I removed a few uninteresting lines.)

    We can see that this new version came from the End Point repository and is very fresh as of the time of this writing.

    Bonus: Newer tmux!

    You may also be interested in our much newer tmux 3.2a vs. the tmux 1.8 that comes with CentOS 7.

    If you want it, now that you have the End Point Yum repository configured, you can simply do:

    $ sudo yum install tmux
