问题描述

如何创建分支？

有人可以向我解释这些语法吗？

How to create a branch?
Could anyone explain these syntax to me?

c版本中显示所有元素

还没有新的分支，将显示 main 的 LATEST 版本，如果发生结帐，则准备创建新分支，

，或者，如果这是一个全新的元素（添加到源e control），将创建版本 / main / 0 ，然后立即分支以在新分支中创建版本1：

display all elements in their LATEST version of the new branch
or, if there is no new branch yet, will display the LATEST version of main, ready to create a new branch if a checkout occurs,
or, if this is a brand new element (an "add to source control"), will create a version /main/0, and then immediately branch in order to create version 1 in the new branch:

（同样，按顺序应用了这3条规则，在第一个合适的位置停了下来，这就是为什么这样排序的原因）

(again, those 3 rules are applied in order, stopping at the first one that fits, which is why they are ordered that way)

这将转换为以下配置规范：

That would translate in the following config spec:

element * .../karthik_4/LATEST
element * /main/LATEST -mkbranch karthik_4
element /main/0 -mkbranch karthik_4

注意：... / karthik_4 / LATEST语法是为了不将 karthik_4 分支绑定到main：即使 karthik_4 在主的任何其他分支的顶部（这就是 ... / ），它仍然会选择该新分支的最新版本（如果存在，如果不存在，则ClearCase尝试下一条规则）。

Note: the .../karthik_4/LATEST syntax is there in order to not tie karthik_4 branch to main: even if karthik_4 was created on top on any other branch that main (which is what .../ means), it would still select the LATEST version of that new branch (if it exists, if not ClearCase tries the next rule)

创建分支始终涉及3条规则，

Creating a branch always involve 3 rules, not just one.

现在，作为，这不会从特定版本（如 4）创建分支。 br>
它将仅在主分支上以其最新版本的文件版本创建分支：LATEST被称为移位标签：在每个新版本上它都会自动移位。

Now, as you saw earlier, this won't create a branch from a specific version (like '4').
It will only create a branch at whatever version a file is in its LATEST version on the main branch: LATEST is called a shifting label: it shifts automatically at each new version.

您可以为一个文件指定要从中创建分支的确切版本：

You could specify, for one file, the exact version you want to create a branch from:

element * .../karthik_4/LATEST
element /path/to/myFile /main/4 -mkbranch karthik_4
element * /main/LATEST -mkbranch karthik_4
element /main/0 -mkbranch karthik_4

但这很难扩展，因为旁边的文件myFile 可能有不同的历史记录，其版本4可能早于 myFile @@ / main / 4 或之前创建的（或其他文件可能还不存在版本4！）。

But that won't scale easily, since the file next to myFile is likely to have a different history, and its version 4 might have been created long before or after myFile@@/main/4 (or version 4 might not exist yet for the other files!).
