You and Bob both made changes to the same file yours into the re;poyou just got sitory first. Do you think Microsoft is still making fixes to Word 95? You'll gain essential information about each step of the software development lifecycle -- requirements, design, coding, testing, implementing, and maintenance -- and understand why and how different development processes work. Earlier, we talked about the planning and execution parts of a project, and then we got a little closer to code and talked about design. Every time you commit code into your version control system, a revision number was attached to the software at that point. Q: Earlier, you said not to commit changes to a tag. There are several reasons for this dynamic: First, new technologies are emerging, as a result, the equipment is being improved and that, in turn, requires software changes. Mark: So you just overwrote it?? That means that to get a copy of a project at a certain state, you need to know the version numbers of each file.
Bob really blew it with that demo. Using the log messages above, which revision do you think matches up with Version 1. Branches and tags code so you can find and change versions of code from way back when. Version control tools all do pretty much the same thing, but some offer different ways to do it. Finally, our industry has found a real, sustainable way to solve problems that have perplexed generations of software developers. Did you say that Bob should branch his code to support the two different features? Time for the next iteration? The code you just looked at, in the last exercise, is the network code.
The Zen of good branching Branch only when you absolutely have to. Now, commit the file to your server, adding a comment indicating what you did. In fact, a good version control tool is really the only way you can scale a team. Based on the latest research in cognitive science and learning theory, Head First Android Development uses a visually rich format to engage your mind, rather than a text-heavy approach that puts you to sleep. You'll learn how to think lik.
Dan has written several books on software development, including? Modern version control tools do make branching cheap from a technical perspective. His task is working, so he copies his code up to the server. Dan Pilone and Russ Mile are the authors of this book. BeatBox is a multi-player drum machine that lets you send messages and drum loops to other users over the network. Good design, good division of labor, frequent commits, and good communication help reduce the number of manual merges you actually have to do.
Did that fix get applied to the trunk so that it stays fixed in Version 2. You guys really got your stuff together. Why are we wasting time looking through all this code? Each branch is a potentially large piece of software you have to maintain, test, release, and keep up with. With its unique visually rich format, this book pulls together the hard lessons learned by expert software developers over the years. I just found a bug in the way images are handled in our Send Picture feature from way back in the first iteration. Q: A: Q: A: On the receiving side we pull off the secret sequence and the array of checkboxes.
New features would have to be implemented to both branches. MusicServer We use different names here so we know which is which. Then, other versions would go into a directory called branches. When you create a copy, Subversion actually just marks the revision you copied from, and then stores changes relative to that. Head First iPhone and iPad Development will help you get your first application up and running in no time. Whenever you commit a file, Subversion applies a revision number across the whole project.
Take a look over them all, and see if you can remember what each one means. } catch ke You can re-implement theatPo story, since Bob broke thcode for feature when he wrote the Send Picture story. Things are moving along nicely until. Head First Software Development O? If not, you can download it from the Subversion web site. Makes sure your code is readable and well-written.
Confused about being rational, agile, or a tester. I copied my stuff up with a new name and merged them into the files you had up there. Sometimes you might need to commit the same changes to a branch and the trunk if the change applies to both. Stick with Head First Software Development, and your projects will succeed like never before. If you have an idea for a killer Android app, this book will help you build your first working application in a jiffy. Instead of surrendering to these common problems, let Head First Software Development guide you through the best practices of software development.
