好吧，你可以有自己的分支，你可以随时提交，当你完成你的特性时，你可以将它合并到主干。

关于提交的频率，我是这样想的，如果我的硬盘崩溃了，而我没有提交一些东西，这对我来说有多痛苦-这个东西对我来说大约是2个小时的工作。

当然，我从不提交不能编译的东西。

如果你的版本控制注释超过了一两句话，你可能没有经常提交。

每次我完成一项任务时，我都会做出承诺。这通常需要30分钟到1小时。

如果您正在进行重大更改，并且担心会影响其他使用代码的人，那么您可以创建一个新的分支，然后在更改完成后合并回主干。

我觉得你不用太担心多久来一次。重要的是什么，什么时候，为什么。说你必须每3小时或每24小时完成一次任务是毫无意义的。有事情要承诺时就承诺，没有事情就不要承诺。

以下是我推荐的版本控制最佳实践的摘录:

[...] If you are doing many changes to a project at the same time, split them up into logical parts and commit them in multiple sessions. This makes it much easier to track the history of individual changes, which will save you a lot of time when trying to find and fix bugs later on. For example, if you are implementing feature A, B and C and fixing bug 1, 2 and 3, that should result in a total of at least six commits, one for each feature and one for each bug. If you are working on a big feature or doing extensive refactoring, consider splitting your work up into even smaller parts, and make a commit after each part is completed. Also, when implementing independent changes to multiple logical modules, commit changes to each module separately, even if they are part of a bigger change. Ideally, you should never leave your office with uncommitted changes on your hard drive. If you are working on projects where changes will affect other people, consider using a branch to implement your changes and merge them back into the trunk when you are done. When committing changes to libraries or projects that other projects—and thus, other people—depend on, make sure you don’t break their builds by committing code that won’t compile. However, having code that doesn’t compile is not an excuse to avoid committing. Use branches instead. [...]

这取决于您的源代码系统和您所拥有的其他内容。如果您正在使用Git，那么每当完成一个步骤时就提交。我使用SVN，我喜欢在完成整个功能后提交，所以，每1到5个小时提交一次。如果我使用CVS，我也会这么做。
