Many developers have switched to SVN as it is a newer technology that takes the best features of CVS and improves upon them.Version control, also called subversion control, or revision control, helps large projects from spinning out of control by letting individual programmers, writers, or project managers tackle a project from different angles without getting in each others way and without doing damage that cant be undone.Theres a great visual introduction to version control here if you are completely unfamiliar with the concept.
Simple Version Control Software Can HelpSee how Time Doctors easy-to-use time tracking software can help your team be more productive. If you prefer a video explanation, check this one from GitHub instead: So, which version control is right for your project There are a number of solutions out there, and so weve put together a definitive feature comparison so you can decide the best solution for you. This is a fairly technical topic, so if you dont have a software background, read our comparison carefully, and consult with your lead technical personnel before you make any final decisions. Version control software, including the well known SVN and Git, was designed from the ground up to allow teams of programmers to work on a project together without wasting man-hours on paperwork. Simple Version Control Code And AssociatedInstead of manually scanning branches of code and associated notes, version control allows for a central repository that is organized, logical, and facilitates file updates, notation, and even merging. There are a lot of opinions regarding which version control framework is the best, and can force programmers and project management teams into fierce debate. When choosing the right version control for your project, you should consider that some of pros of one package you will come across are subjective, meaning the opinion of the programmer, and other factors, such as speed and IDE plug-in capabilities, overshadow the raw numbers. The main difference between version control systems is whether they are server based or peer-to-peer. Either they have a centralized repository where code is checked out and back in with changes, or a setup where the code is frequently updated from peer sources, a more decentralized network, to keep code current. Beyond that, you will also want to consider speed, functionality, and the learning curve associated with the system. To decide which one is right for your project and team, lets take a look at some of the major systems available and the reasons why some programmers prefer one over the other. Concurrent Versions System (CVS) CVS has been around since the 80s, and has been very popular with both commercial and open source developers. ![]() Originally, CVS handled conflicts between two programmers by only allowing for the latest version of the code to be worked on and updated. As such, it was a first come, first serve system where the user must publish changes quickly to ensure that other users havent beat them to the punch. Now, CVS can handle branching projects so the developed software can diverge into different products with unique features and will be reconciled at a later time. The CVS server runs on Unix-like systems with client software that runs on multiple operating systems. It is considered the most mature version control system because it has been developed for such a long time and does not receive many requests for new features at this time. A fork project of CVS, CVSNT was created to run CVS on Windows servers, and it is currently being actively developed to increase functionality. Pros: Has been in use for many years and is considered mature technology Cons: Moving or renaming files does not include a version update Security risks from symbolic links to files No atomic operation support, leading to source corruption Branch operations are expensive as it is not designed for long-term branching Apache Subversion (SVN) SVN was created as an alternative to CVS that would fix some bugs in the CVS system while maintaining high compatibility with it. Simple Version Control Free And OpenLike CVS, SVN is free and open source with the difference of being distributed under the Apache license as opposed to GNU. To prevent corruption in the database from being corrupted, SVN employs a concept called atomic operations. Either all of the changes made to the source are applied or none are applied, meaning that no partial changes will break the original source.
