我个人会提交每一组已完成/稳定/编译的逻辑代码，并尽量在没有提交我当天所做的事情的情况下下班。

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。

我喜欢每30-60分钟提交一次更改，只要它编译干净，并且在单元测试中没有回归。

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. [...]

不要提交实际上不起作用的代码。不要将存储库用作备份解决方案。

相反，以自动的方式在本地备份不完整的代码。时间机器会照顾我，还有很多其他平台的免费程序。

每当我对编译和运行的代码进行“全面思考”时，我都会签入。这通常会持续15到60分钟。有时它可能会更长，但我总是尝试签入如果我有很多代码更改，我不想在失败的情况下重写。我通常也会确保我的代码被编译，并且在下班回家前检查。

我不会担心提交/签入“太多”。当您不得不重写某些内容时，这真的很糟糕，并且能够以小增量回滚以防万一是很好的。
