Version Control with Subversion. Chapter 1.  Fundamental Concepts. This chapter is a short, casual introduction to Subversion and. We begin with a discussion of. Subversion, and show some simple examples of. Subversion in use. Even though the examples in this chapter show people sharing. Subversion. can manage any sort of file collectionits not limited to. A version control system or revision control system is a. Of course, merely. What. makes a version control system useful is the fact that it allows. In this section, well introduce some fairly high level. Well limit our. discussion to modern version control systemsin todays. At the core of the version control system is a repository. The. repository usually stores information in the form of a. Any number of. clients connect to the repository, and. Subversion is a freeopen source version control system VCS. That is, Subversion manages files and directories, and the changes made to them, over time. The Portable Document Format PDF is a file format used to present documents in a manner independent of application software, hardware, and operating systems. Each.

Spring_Pro-56946.jpg' alt='Convert Docbook To Pdf Windows 2000' title='Convert Docbook To Pdf Windows 2000' />Why is this interesting So far, this sounds like the. And indeed, the. repository is a kind of file server, but. What makes the repository special. When a client reads data from the repository, it normally. But what. makes a version control client interesting is that it also has. A version control client can ask historical. What did this directory contain last. Wednesday and Who was the last person to. These are the sorts of questions that are at the heart of any. A version control systems value comes from the fact that it. Most software programs understand. So how does a version control. How does his or her word. The answer is found in the version. A working copy is, quite literally, a local copy of a. VCS managed data upon which. Working copies appear to other software. The task of. managing the working copy and communicating changes made to. If the primary mission of a version control system is to. But different systems use different strategies to. Its important to understand these different. First, it will help you. Subversion. Beyond. Subversion, since Subversion itself supports a couple of. The problem of file sharing. All version control systems have to solve the same. Its all too easy for users. Consider the scenario shown in. Figure 1. 2, The problem to avoid. Suppose we have two coworkers, Harry and Sally. They each. decide to edit the same repository file at the same time. If Harry saves his changes to the repository first, its. Sally could accidentally. While. Harrys version of the file wont be lost forever because. Harry made. wont be present in Sallys newer version. Harrys changes to begin. Harrys work is still effectively lostor at. This is definitely a situation we want. Figure 1. 2.  The problem to avoid. The lock modify unlock solution. Many version control systems use a. In this model, the repository allows only one person to. This exclusivity policy is managed. Harry must lock a file before. If Harry has locked a. Sally cannot also lock it, and therefore cannot make. All she can do is read the file. Harry to finish his changes and release his. After Harry unlocks the file, Sally can take her turn. Figure 1. 3, The lock modify unlock solution. Figure 1. 3.  The lock modify unlock solution. The problem with the lock modify unlock model is that its. Locking may cause administrative. Sometimes Harry will lock a file and then forget about it. Meanwhile, because Sally is still waiting to edit the file. And then Harry goes on vacation. Now. Sally has to get an administrator to release Harrys lock. The situation ends up causing a lot of unnecessary delay. Locking may cause unnecessary. What if Harry is editing the beginning of a text file. Sally simply wants to edit the end of the same file These changes dont overlap at all. They could easily. Theres no need for them to take turns in this. Locking may create a false sense of. Suppose Harry locks and edits file A, while Sally. B. But what if A and. B depend on one another, and the changes made to each are. Suddenly A and B dont work. The locking system was powerless to. Its easy for Harry and Sally to. Locking often. becomes a substitute for real communication. The copy modify merge solution. Subversion, CVS, and many other version control systems. In this model, each users client. Users then work simultaneously and. Finally, the. private copies are merged together into a new, final. The version control system often assists with the. Heres an example. Say that Harry and Sally each create. They work concurrently and make changes to the. A within their copies. Sally saves her changes to. When Harry attempts to save his changes. A is. out of date. In other words, file A. So Harry asks his client. A. Chances are. that Sallys changes dont overlap with his own once he has. Figure 1. 4, The copy modify merge solution and. Figure 1. 5, The copy modify merge solution continued show. Figure 1. 4.  The copy modify merge solution. Figure 1. 5.  The copy modify merge solution continuedBut what if Sallys changes do overlap. Harrys changes What then This situation is called a. When Harry asks his client to merge the. A is somehow flagged as being in a state of conflict. Note that software cant. Once Harry has manually resolved the overlapping. Sallyhe. can safely save the merged file back to the. The copy modify merge model may sound a bit chaotic, but. Users can work in. When they work on. And. the amount of time it takes to resolve conflicts is usually. In the end, it all comes down to one critical factor. When users communicate poorly, both. No system can. force users to communicate perfectly, and no system can. So theres no point in being. Version Control the Subversion Way. Weve mentioned already that Subversion is a modern. As we described in. Version Control Basics our. Subversions versioned data, and its. In this section, well begin to. Subversion implements. Subversion implements the concept of a version control. Unlike a working copy, a Subversion repository is an. Subversions own libraries and tools. As most of a users. Subversion interactions involve the use of the Subversion. Subversion working. For the finer details of the. Chapter 5, Repository Administration. A Subversion client commits that is, communicates the. By atomic transaction, we mean. Subversion tries to retain. Each time the repository accepts a commit, this creates a. Each revision is assigned a. The initial revision of a freshly. Figure 1. 6, Tree changes over time. Imagine. an array of revision numbers, starting at 0, stretching from. Each revision number has a filesystem tree. Figure 1. 6.  Tree changes over time. Addressing the Repository. Subversion client programs use URLs to identify versioned. Subversion repositories. For the. most part, these URLs use the standard syntax, allowing for. URL. http svn. Subversion repository URLs arent limited to only. Because Subversion. URLs used to address the repository. Table 1. 1, Repository access URLs. URL schemes map to the available. For more details about. Subversions server options, see. Chapter 6, Server Configuration. Table 1. 1.  Repository access URLs. Schema. Access methodfile Direct repository access on local diskhttp Access via Web. DAV protocol to Subversion aware. Apache serverhttps Same as http, but with. SSL encapsulation encryption and authenticationsvn Access via custom protocol to an. Same as svn, but through. SSH tunnel. Subversions handling of URLs has some notable nuances. For example, URLs containing the file. Also, users of the file scheme on. Freeware List for SPARC and Solaris 1. Please Visit our New Website UNIXPackages.
