I think the answer to your question is a question: Do you want version control or do you want a Software Configuration Management (SCM)? For the most part if you want version control both CVS and VSS offer the same basic features. I have used both for extensive time periods and have found that both have good points and bad points. When selecting one over the other you need to understand what your objects for the long term are. Version control allows for a development centered approach. This works when the business processes are young and immature. In this environment the focus is on “just getting the code out” not necessarily “what is the system doing and in what time frame will it be completed”. It is not unusual in this environment for code to be produced quickly, but projects seem to always be out of control. A good example of this is everyone making whatever changes they want when they want. In a system centered approach, the over all system is looked at and change is more controlled. In this environment code output is lower, but the projects are under more control. A business that has this type of control tends to be a more mature business, form a process stand point, and thus projects are delivered closer to projected timelines, closer to defined requirements, and most often with less feature creep. In this environment change comes only after some sort of analysis. Once you know what your long term goals are it is easy to see what tool fits. Both tools do a good job at version control of source code files. Although VSS does say it supports binary files, it does not do the best job with them. I have found that overall CVS does even worst with binary files. This means that if you are tracking all your supporting files: compilers, libraries, word processing files, etc., that are part of the project - a SCM approach, VSS will do better. If change comes more ad hoc, CVS will better. GUI or not to GUI that is the question. I have found that people with a strong PC background like GUIs and people with a stronger Unix type background tend to like command line interfaces. I have written wrappers for VSS to allow command line interface, and I have used a GUI for CVS. I am not sure that either of these issues are a problem or not, I think that they are more of personal choice. Moving files from one project to an other may be easier in CVS than VSS, but both support this feature. Both allow the merging of changes and both branch code bases. These areas are about the same. They both fail miserably to merge two development versions back into one main branch, but I think that this is due to the fact that there has yet to be a system to understand how to do this well from a SCM standpoint. VSS allows for a required check out to edit a file. This is a strong feature if the development environment is one of controlled change. The labeling for a build identifier is better in VSS than in CVS, as well as the process of recreation of a build from a label. Not that these features do not exist in CVS, but they are not as flexible. In version 4 of VSS, the repository had many problems with stability. In version 5 it was more stable, but I had some problems with both. Once I moved to a version 6 repository I did not have these types of problems. Just a point to remember. In closing I would like to say that both tools have their strengths and weakness. What will define which is best to use will come down to what are your long term goals. These are just some of my thoughts.

I've heard a lot of bad yet it's still widely used. I have a situation where we are currently using Microsoft VSS which also seems to be part of Server 2003 now. The developers 'hate' VSS and want something else. Their history with other Source Control systems also have poor reviews from them. None of them have used CVS so CVS sounds attractive to them. The other attractive note about CVS is that our Mac clients can now have source control. I've been given a 'go' to investigate CVS, do some installations, backups, catastrophic failures of server, restores, etc... I'd like to see some opinions on it because I've never heard "CVS is great!". Either we go ahead and convert all our VSS to CVS or just put up with VSS. If we go with CVS, I can justify getting a new server and also have Postfix running on it to get rid of our spam. --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change you mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change you mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
