How many people use subversion

Not near perfect, because particularly "git" has other uses too, but all popularity measures are more or less BS anyway. Defining popularity is tough. You could do something like this In addition, this graph indicates a much smaller decline in "svn" than is shown in "subversion". Also, the algorithm is detecting "subversion" as meaning "corruption" or "undermining loyalty" rather than the version control system.

I'd suspect that "svn" is more appropriate to the development tool. I would not switch it for SVN, ever, which as you said is often a loss of time, and I will not switch to a non controlled version system.

But now I use SVN. Even for a single user working on tiny projects, it has distinct advantages. It keeps the entire history of the project, not just one or two previous versions. It keeps log messages with every updates so I can go back and see what I did. If I see a problem, I can easily compare to earlier versions to see where the bug was introduced. When it worked out, I merged it back into trunk.

I find it adds very little effort to use. This is crazy. SVN has no significant advantages over Hg or Git, regardless of team size. There are a number of solutions out there, and you need to do definitive feature comparison so you can decide the best solution that is best for you.

I use Git both at work and for personal rjepocts. Its superior branch merging and local branching capability are great advantages over Subversion.

Git is very powerful but as a result has lots and lots of commands, options and features that are confusing and unnecessary for everyday use. However I found that once you learn how to do the basics, you can get by perfectly fine. There is absolutely no need to set up server or such a thing. Possibly "destructive" features or "destructive power" as you call it are not turned on by default so that no data is lost by default.

Start working. Mercurial exposes a clean public Python API, thus many features in Mercurial are moved out to optional extensions in order to keep the core set of commands clean.

I use it on my Ubuntu However, some purists actually shy away from gui-fied SVN clients and use the terminal client instead since it offers much more scripting flexibility and what not. Not necessary to talk about CVS, I think, it is a dinosaur. One of its big disadvantage — it does not allow to version folders directories. Good enough for small teams. Latest XCode 4.

Very interesting to try git, to learn something new and because it better work with branches as people say. Also it has good clients for all platforms. Also I like that it stores meta information only in root folder, unlike svn has.

Also it is very good that git is faster — critical for big projects. Also need to mention following clients: TortoiseGit — open source client for Windows. GitX SmartGit — commercial.

However, a complicated abstraction model is not mandatory for DVCS: the competing DVCS called Mercurial has a much more consistent abstraction model and provides a cleaner command line syntax.

It's worth to note that Subversion is as easy and safe as any version control should be. Additional information: Mercurial vs Git: Why Mercurial? In contrast, with Subversion you always can get exactly the same data from your repository as it was in any moment in the past. Also you can easily trace all changes made to the particular file or folder, because Subversion history is permanent and always definite. Example: losing history after rename in Git. Because of the distributed nature of Git, each Git user has the full copy of the repository and effectively has the complete read access to the entire content of the repository.

While this approach is sufficient for open source repositories that rarely contain any confidential information, it could be not acceptable for most of the enterprise projects. At the same time Subversion provides a path-based authorization system that allows to granularly control who is authorized to read and modify files in the repositories and is sufficient even for large enterprise installations.

Modern version control systems are based on the assumption that most of the versioned files are mergeable. In other words, it should be nearly almost possible to merge two concurrent changes made to a single file. Since Git is inherently distributed, it does not support exclusive files locks at all. This makes it hard to adopt Git for enterprise projects where a lot of non-mergeable binary assets usually exist. The following example is designated to show that the size difference of Subversion and Git repositories is insignificant.

The example is based on the comparison of the size of the official WordPress codebase repository which is powered by Subversion and its mirror hosted on GitHub. The sizes of Subversion and Git repositories are pretty the same: MB in Subversion revisions vs. Git repository is only 17 MB less than the corresponding Subversion repository, however it has less revisions as well in Subversion vs. The following example is designated to show that making a branch in Subversion is very cheap in time and space and that there is no significant difference when compared to Git.

Starting today, those scenarios, and many more, are possible on GitHub at no cost. Navigate to the TortoiseSVN choice, you'll see its main menu. This is where you can choose a version control action you want to take against that file or folder.

Why is git considered better than CVS for version control system? The main difference is that as it was already said in other responses CVS is old centralized version control system, while Git is distributed.

But even if you use version control for single developer, on single machine single account , there are a few differences between Git and CVS: Setting up repository. Probably the biggest improvement to SVN is the addition of atomic commits. Atomic commits allow each commit to be applied in full or not at all. What is subversion tool? That is, Subversion manages files and directories, and the changes made to them, over time.

This allows you to recover older versions of your data, or examine the history of how your data changed. We use a Subversion bridge to communicate svn commands to GitHub. Why do we use SVN? SVN stands for Subversion and is a version control system.
