Max length of git branch name
提问by MikDiet
I want to understand what is maximum allowed size of a git branch name.
我想了解 git 分支名称的最大允许大小是多少。
I am trying to create some long names (as an experiment) so a name with 370 characters was valid, but 380 characters gave me fatal: Failed to lock ref for update: File name too long
我正在尝试创建一些长名称（作为实验），因此 370 个字符的名称是有效的，但是 380 个字符给了我 fatal: Failed to lock ref for update: File name too long
So the questions is: what is the maximum number of characters that can be in git branch name? Does it depend on the system? Is it possible to create long branch name in a repository that will be rejected on remote repository (i.e. Github)?
所以问题是：git 分支名称中可以包含的最大字符数是多少？它取决于系统吗？是否可以在远程存储库（即 Github）上拒绝的存储库中创建长分支名称？

The 'File name too long' is indeed an error coming from your system. It is not a restriction in Git. I don't think there's a way of testing the maximum branch name lengths of other systems, like GitHub's, without experimenting - although I don't see why you would want to know...
“文件名太长”确实是来自您的系统的错误。这不是 Git 中的限制。我不认为有一种方法可以测试其他系统的最大分支名称长度，如 GitHub 的，而不进行实验——尽管我不明白你为什么想知道......

Source: the error mentioned is thrown on line 291 of branch.c. "File name too long" is the standard description for the ENAMETOOLONG error.
来源：提到的错误是在第 291 行抛出的branch.c。“文件名太长”是 ENAMETOOLONG 错误的标准描述。
