Do you know the birthday of git?

April 6, 2005: The git project was made public for the first time

Git is a distributed version control software, originally created by Linus Torvalds, the father of Linux, on April 6, 2005 Released under the GPL license. Originally designed to better manage Linux kernel development. The day after the release, git was implemented as its own version control tool, so April 7 is generally regarded as the birth date of git. Git is currently the most popular open source distributed version control system in the world. It was originally developed by Linus Torvalds and later handed over to Jun Hamano.

The initial development impetus for git came from BitKeeper and Monotone; git was originally developed as a backend that could be wrapped by other frontends (such as Cogito or Stgit), but later the git kernel has matured enough to be used independently. For version control. Many widely used software projects use git for version control, including the development process of projects such as the Linux kernel, X.Org server, and OLPC kernel.

Since 2002, Linus Torvalds decided to use BitKeeper as the main version control system for the Linux kernel to maintain the code. Because BitKeeper is proprietary software, this decision has long been met with skepticism in the community. In the Linux community, members of the Free Software Foundation, represented by Richard Stallman, advocate that open source software should be used as the version control system of the Linux kernel. Linus Torvalds also considered using off-the-shelf software as a version control system (such as Monotone), but these software had some problems (such as poor performance). Other off-the-shelf solutions, such as CVS's architecture, were criticized by Linus Torvalds.

In 2005, Andrew Tridgell wrote a simple program that could connect to the BitKeeper repository; BitKeeper copyright owner Larry McEvoy believed that Andrew Tridgell used BitKeeper internally reverse-engineered the agreement and decided to withdraw the license to use BitKeeper for free. The Linux kernel development team negotiated with BitMover Corporation, but were unable to resolve their differences. After losing BitKeeper, Linus Torvalds could only decide to develop his own version control system to replace BitKeeper. In the end, he wrote the first version of git in C language in ten days.

In fact, when the Linux kernel development team decided to start developing and using git as the version control system for kernel development, there was a lot of opposition from the open source community around the world. The biggest reason was that git was too difficult to understand; But as development progresses, normal use of git is performed by some friendly commands, making git very easy to use. As an open source freedom fundamentalist project, git does not impose any permission restrictions on browsing and modifying the repository, and limited permission control can also be achieved through other tools. Originally, the scope of use of git was only applicable to Linux/Unix platforms, but its use on Windows platforms has become increasingly mature. This is mainly due to Cygwin, msysgit environment, and easy-to-use GUI tools such as TortoiseGit. The source code of git has also added support for Cygwin and MinGW compilation environments and is gradually improving, bringing good news to Windows users.
