Introduction to Git

Git is a free and open source, distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Every Git clone is a full-fledged repository with complete history and full revision tracking capabilities, not dependent on network access or a central server. Branching and merging are fast and easy to do. Git is used for version control of files, much like tools such as Mercurial-5.7, Bazaar, Subversion-1.14.1, CVS, Perforce, and Team Foundation Server.

This package is known to build and work properly using an LFS-10.1 platform.

Git Dependencies



pcre2-10.36 (or the deprecated PCRE-8.44), in either case configured with --enable-jit, Subversion-1.14.1 with Perl bindings (for git svn), Tk- (gitk, a simple Git repository viewer, uses Tk at runtime), and Valgrind-3.16.1

Optional (to create the man pages, html docs and other docs)

xmlto-0.0.28 and asciidoc-9.1.0 or AsciiDoctor, and also dblatex (for the PDF version of the user manual), and docbook2x to create info pages

User Notes:

Installation of Git

Install Git by running the following commands:

./configure --prefix=/usr \
            --with-gitconfig=/etc/gitconfig \
            --with-python=python3 &&

You can build the man pages and/or html docs, or use downloaded ones. If you choose to build them, use the next two instructions.

If you have installed asciidoc-9.1.0 you can create the html version of the man pages and other docs:

make html

If you have installed asciidoc-9.1.0 and xmlto-0.0.28 you can create the man pages:

make man

The test suite can be run in parallel mode. To run the test suite, issue: make test. If run as a normal user, 0 tests should be reported as failed in the final summary.

Now, as the root user:

make perllibdir=/usr/lib/perl5/5.32/site_perl install

If you created the man pages and/or html docs

Install the man pages as the root user:

make install-man

Install the html docs as the root user:

make htmldir=/usr/share/doc/git-2.30.1 install-html

If you downloaded the man pages and/or html docs

If you downloaded the man pages untar them as the root user:

tar -xf ../git-manpages-2.30.1.tar.xz \
    -C /usr/share/man --no-same-owner --no-overwrite-dir

If you downloaded the html docs untar them as the root user:

mkdir -vp   /usr/share/doc/git-2.30.1 &&
tar   -xf   ../git-htmldocs-2.30.1.tar.xz \
      -C    /usr/share/doc/git-2.30.1 --no-same-owner --no-overwrite-dir &&

find        /usr/share/doc/git-2.30.1 -type d -exec chmod 755 {} \; &&
find        /usr/share/doc/git-2.30.1 -type f -exec chmod 644 {} \;

Reorganize text and html in the html-docs (both methods)

For both methods, the html-docs include a lot of plain text files. Reorganize the files as the root user:

mkdir -vp /usr/share/doc/git-2.30.1/man-pages/{html,text}         &&
mv        /usr/share/doc/git-2.30.1/{git*.txt,man-pages/text}     &&
mv        /usr/share/doc/git-2.30.1/{git*.,index.,man-pages/}html &&

mkdir -vp /usr/share/doc/git-2.30.1/technical/{html,text}         &&
mv        /usr/share/doc/git-2.30.1/technical/{*.txt,text}        &&
mv        /usr/share/doc/git-2.30.1/technical/{*.,}html           &&

mkdir -vp /usr/share/doc/git-2.30.1/howto/{html,text}             &&
mv        /usr/share/doc/git-2.30.1/howto/{*.txt,text}            &&
mv        /usr/share/doc/git-2.30.1/howto/{*.,}html               &&

sed -i '/^<a href=/s|howto/|&html/|' /usr/share/doc/git-2.30.1/howto-index.html &&
sed -i '/^\* link:/s|howto/|&html/|' /usr/share/doc/git-2.30.1/howto-index.txt

Command Explanations

--with-gitconfig=/etc/gitconfig: This sets /etc/gitconfig as the file that stores the default, system wide, Git settings.

--with-python=python3: Use this switch to use Python 3, instead of the EOL'ed Python 2. Python is used for the git p4 interface to Perforce repositories, and also used in some tests.

--with-libpcre2: Use this switch if PCRE2 is installed and has been built with the non-default JIT enabled.

--with-libpcre: As an alternative to PCRE2, use this switch if the deprecated PCRE is installed and has been built with the non-default JIT enabled.

tar -xf ../git-manpages-2.30.1.tar.gz -C /usr/share/man --no-same-owner: This untars git-manpages-2.30.1.tar.gz. The -C option makes tar change directory to /usr/share/man before it starts to decompress the docs. The --no-same-owner option stops tar from preserving the user and group details of the files. This is useful as that user or group may not exist on your system; this could (potentially) be a security risk.

mv /usr/share/doc/git-2.30.1 ...: These commands move some of the files into subfolders to make it easier to sort through the docs and find what you're looking for.

find ... chmod ...: These commands correct the permissions in the shipped documentation tar file.
