David Richards关于Subversion / GIT的WANdisco博客

The emergence of GIT has brought with it a breed of DVCS fundamentalists – the ‘Gitterons’ – that think anything other than GIT is crap. The Gitterons seem to think software engineering happens on their own island and often forget that most organizations don’t employ senior software engineers exclusively. That’s ok but it’s not how the rest of the market thinks, and I am happy to prove it: GIT, at the last look had less than three per cent of the market while Subversion has in the region of five million users and about half of the overall market. The problem we saw was that the Gitterons were firing (cheap) shots at Subversion. Tweets like “Subversion is so [slow/crappy/restrictive/doesn't smell good/looks at me in a funny way] and now I have GIT and [everything works in my life/my wife got pregnant/I got a girlfriend after 30 years of trying/I won six times running on the blackjack table]. You get the picture.

Easy Git有一个很好的页面，比较了Git和SVN的实际使用情况，这将让你了解Git可以做什么(或更容易做什么)。(从技术上讲，这是基于Easy Git的，它是Git之上的轻量级包装器。)

其他的回答很好地解释了Git的核心特性(这些特性非常棒)。但是还有很多小方法可以让Git表现得更好，并帮助我的生活更加理智。以下是一些小细节:

Git has a 'clean' command. SVN desperately needs this command, considering how frequently it will dump extra files on your disk. Git has the 'bisect' command. It's nice. SVN creates .svn directories in every single folder (Git only creates one .git directory). Every script you write, and every grep you do, will need to be written to ignore these .svn directories. You also need an entire command ("svn export") just to get a sane copy of your files. In SVN, each file & folder can come from a different revision or branch. At first, it sounds nice to have this freedom. But what this actually means is that there is a million different ways for your local checkout to be completely screwed up. (for example, if "svn switch" fails halfway through, or if you enter a command wrong). And the worst part is: if you ever get into a situation where some of your files are coming from one place, and some of them from another, the "svn status" will tell you that everything is normal. You'll need to do "svn info" on each file/directory to discover how weird things are. If "git status" tells you that things are normal, then you can trust that things really are normal. You have to tell SVN whenever you move or delete something. Git will just figure it out. Ignore semantics are easier in Git. If you ignore a pattern (such as *.pyc), it will be ignored for all subdirectories. (But if you really want to ignore something for just one directory, you can). With SVN, it seems that there is no easy way to ignore a pattern across all subdirectories. Another item involving ignore files. Git makes it possible to have "private" ignore settings (using the file .git/info/exclude), which won't affect anyone else.

我非常喜欢能够在Git中管理源代码的本地分支，而不会混淆中央存储库的水。在许多情况下，我将从Subversion服务器签出代码并运行本地Git存储库，只是为了能够做到这一点。初始化Git存储库不会因为到处都是烦人的.svn文件夹而污染文件系统，这一点也很棒。

至于Windows工具的支持，TortoiseGit处理基本的很好，但我仍然喜欢命令行，除非我想查看日志。我真的很喜欢Tortoise{Git|SVN}在读取提交日志时的帮助方式。

Git和DVCS通常都非常适合于独立编写大量代码的开发人员，因为每个人都有自己的分支。但是，如果您需要从其他人那里进行更改，她必须提交给她的本地回购，然后她必须将该更改集推给您，或者您必须从她那里获取更改集。

我自己的推理也让我认为，如果你做集中发布之类的事情，DVCS会让QA和发布管理变得更加困难。必须有人负责从其他人的存储库中进行推送/拉取，解决任何在最初提交时就可以解决的冲突，然后进行构建，然后让所有其他开发人员重新同步他们的回购。

当然，所有这些都可以通过人工流程来解决;DVCS只是破坏了一些由集中式版本控制修复的东西，以便提供一些新的便利。

Subversion仍然是一种更常用的版本控制系统，这意味着它有更好的工具支持。您会发现几乎所有IDE都有成熟的SVN插件，并且有很好的资源管理器扩展可用(如TurtoiseSVN)。除此之外，我不得不同意Michael的观点:Git并不比Subversion更好或更差，它是不同的。
