As shown with the workflows, you can use it to fit almost any scenario of users and setups. Local machines mirror the same version database. All developers work checkout from that source, and then add commit their changes, which then become similarly Blessed.

Naturally these are stored as separate pieces of work in the version history. The good and the bad essentially from an updated because some old arguments are not true anymore compilation of blogs and my personal experience. The other issue is that using hooks to rollback or filter pushes creates a window where someone could accidently pull changes that will be rolled back, so you have to use a pair of repositories, one for pushes and one for pulls, with an automatic sync after the hooks run to sync them up.

About distributed version control

This chapter will be about getting started with Git. We distributed version control begin by explaining some background on version control tools, then move on to how to get Git running on your system and finally how to get it set up to start working with. At the end of this chapter you should understand why Git is around, why you should use it and you should be all set up to do so. Version control distributed version control a system that records changes to a file or set of files over time so that you can recall specific versions later. For the examples in this book, you will use software source code as the files being version controlled, though in reality you can do this with nearly any type of file on a computer. It allows you to revert selected files back to a previous state, revert the entire project back to a previous state, compare changes over time, see who last modified something that might be causing a problem, who introduced an issue and when, and more. In addition, you get all this for very little overhead. This approach is very common because it is so simple, but it is also incredibly error prone. The next major issue that people encounter is that they need to collaborate with developers on other systems. For many years, this has been the standard for version control. For example, everyone knows to a certain degree what everyone else on the project is doing. However, this setup also has some serious downsides. The most obvious is the single point of failure that the centralized server represents. Thus, if any server dies, and these systems were collaborating via that server, any of the client repositories can be copied back up to the server to restore it. Every clone is really a full backup of all the data. Furthermore, distributed version control of these systems deal pretty well with having several remote repositories they can work with, so you can collaborate with different groups of people in different ways simultaneously within the same project.

Git quiz questions recap So, how did you do on these introductory Git quiz questions for beginners? It's commonly used in software development to manage source code project. I hope you will enjoy it. It has, of course, been copied by Hg and bzr, so it's no longer unique to git. Thus, if any server dies, and these systems were collaborating via that server, any of the client repositories can be copied back up to the server to restore it. I need to see if it works before I push to the experimental branch. If you do a lot of development on laptops while traveling then this might be more of a consideration for you. No solution will ever be a magic bullet. We also see how you can make use of repository hosting from sites such as BitBucket and GitHub. For example, say a developer, Alice, makes changes to source code, adding a feature for the upcoming 2.
