![]() Two of the most popular areīitkeeper, etc.) exist. Even relatively simple operations, like a file rename, can throw a well-formed CVCS patch out of the window.ĭistributed Version Control Systems (DVCS) are a family of version control systems unlike those with which many are familiar. Although they record the version of the file they were patched against, the patch itself is sensitive to big changes in the file, sometimes leading to the patch being inapplicable. These are generally performed against HEAD (a snapshot in time) and then applied later (sometimes months or evenĮight years later). The second problem is simply an artifact of the way in which patches work. Road warriors (those with laptops and who code from the local coffee shop) tend to operate in a more frequently disconnected mode, which limits repository functionality to when they are connected. Those in the same continent will rarely experience delays due to global network variation in addition, they tend to be employed in an organisation and sit at a desktop connected to wired networking for most of the day. ![]() The first problem is rarely apparent for those working with Eclipse in a location at (or near) the repository itself. However, in general, you are prevented from doing many of the operations that are possible while connected.) (A note on SVN: since SVN keeps the last-known checkout, it's possible to do a limited set of operations while disconnected from SVN, like diff from the last-known checkout. when it is time to apply the patch, HEAD is different than it was when the patch was generated). Patches generated against a particular branch can become outdated fairly quickly as development of the snapshot-in-time branch moves on (e.g.You need to be 'online' to perform actions, like diff or patch.Two problems surface with a centralised version control system, although they aren't immediately obvious: Patch, which is a diff of your code against the given Master repository version (often HEAD, but sometimes a branch like Eclipse_35). ![]() For code that needs to be sent person-to-person (for example, for review, or as a way of contributing fixes), it is possible to create a That is, there is one Master repository where people share code everyone checks out their code (or branch) from that repository, and checks changes back in. So, what do you need to know about Git? Well, both CVS and SVN are known asĬentralised version control systems (CVCS). Once you start to use a DVCS, it's very unlikely you'll want to go back Centralised version control systems You should really start to experiment only if you think you're going to migrate in the near future, because using Git is like watching TV in colour: once you've discovered it, it's really difficult to go back to black & white. Once you understand the conceptual differences between CVS/SVN and Git, and then subsequently start to use Git, you may find it very difficult to go back. Other sites can give those flavours if needed. This post is not about the relative merits of Git over CVS/SVN, or of Git versus other distributed version control systems (DVCS) like Mercurial (Hg). The content of the post is about Git: what it means to you, as an Eclipse user, and specifically, how it affects how you obtain or work with projects from. This post is aimed at those who have been using Eclipse for a while, and probably have been using either the baked-in CVS or external SVN providers to store their source code.
