Apache Subversion Reviews

Retain a history of changes to a set of files

Allow multiple people to collaborate on a set of files and merge changes together

Easy install

Integrates into agile project standards

Revision regressions tracking in projects

Manage different version of tracked files.

Has great support from other development tools and systems.

Well documented and maintained.

Great ecosystem and online communities.

Track and control concurrent versions of the same files.

Has good support from many different software, including visualization, DevOps toolchain.

Well documented and understood by developers as it has been around for a long time.

Revision control done properly - you have end to end visibility of all changes in the project.

Conflict resolution - visually highlighting the differences helps to track down the problem.

Being open source and very popular.

We are using SVN hosted in our network - it is very stable, we had almost zero downtime in 4 years.

Rollbacks are made simple and easy to use.

Software versioning

Very stable product

Easy to use

Version control - it's what it's designed for.

Modifiable - It only takes a little bit of knowledge of a scripting language (I used Windows BAT files calling Perl scripts) to extend capabilities, like the aforementioned integration with Redmine.

Back end administration- It's a breeze. There's very little work involved in terms of administering it once you've got it installed on a server, and even setting that up isn't bad.

Old is gold. Apache Subversion has existed before many other version control systems, including Git. It's old, stable, and easy to use with not many complications.

Excellent versioning system. You can jump between any particular version of your project to any other version just by reverting or updating, you can also create patches of your own changes and then apply the patch on your own system on a different check out or on someone else's computer who has a checkout copy.

You can search for any older commit by using words used in the comment log or by using an exact commit number or anything in between. You can also check the log of each and every individual file instead of the whole checkout.

Tortoise SVN is a client for Apache Subversion. It has one of the best UIs I have ever seen for a version control system.

Can be used from many locations, like a cloud-based system but with more custom control--and its free!

Multiple projects easily stored in a single repository, which aids in maintenance of common code, yet also easily allows for separate repositories where no sharing is desired.

Very stable, with lots of additional tools to help maintain and examine repositories (e.g. websvn).

Much easier to understand when coming from more traditional SCM systems like CVS and Perforce (as opposed to Git, which is a bit of a paradigm shift).

The default conflict resolution option, to merge locally, has led to a much more efficient work environment when working with large teams on large codebases. The traditional single-person file locking can really get in the way of team work, as you have to wait for your team member to finish their changes before you can start working on the same file, even if they called in sick for work that day. While sometimes this requires manually figuring out what to do when two changes affect the same line of code, most of the time the changes are on the same lines of the file, and merging can happen transparently.

I have enjoyed the branching process in subversion. Branches and tags are not strict features of the product, which allows for fudgibility, but when you use the recommended trunk/tags/branches folder layout, it behaves as if it was built it. Implemented simply as copy/branch and merge functions, I have found them to work just as well as a built it system would work, and it does a good job pointing out issues with a change's ancestry.

Subversion also have a rich ecosystem of third-party tools and service providers. I personally have used TortoiseSVN for years, but there are several plugins that integrate directly into Visual Studio or Eclipse. Also, I have found hosting services like CVSDude (now called CloudForge) to be a big time-saver over hosting a repository on your own servers, while providing peace of mind that your code-base is in a different physical location, in case say, your server farm burned down. (I'd call that a serious edge condition, but my job involves edge conditions!)

User friendly and easy to learn and understand

Free software

Easy to keep track of code versions
