从Clearcase复制具有特定标签的元素，而不使用配置规范 [英] Copying an element from Clearcase with a particular label without using config specs

问题描述

如何从带有特定标签的 Clearcase 复制元素或文件，而不应用该<$ c $在配置规范中的c> label 。

我不想更改我的视图的配置规范，但是我需要访问所选文件之一的旧版本，我想直接从现有视图中访问（再次，不做任何更改）。

我知道我要还原的版本（从实例版本2，即使我在视图中选择了当前版本3）。

什么 cleartool 您将使用命令访问旧版本吗？

解决方案

您可以使用：

如果将版本标签定义为每个元素，一个附加的链接/文件系统对象将出现在元素目录树的顶层。

例如，如果 BL3 是每个元素的标签，则这些版本扩展的路径名都是对相同对象的明确引用版本：

  hello.c @@ / BL3 
 hello.c @@ / main / bugfix / patch2 / BL3 
  

实际上，此功能使您可以引用版本而无需知道版本树中的确切位置。

在动态视图中，当您在视图中看到hello.c（并且可以是任何个选定的版本，而不是您想要的带有标签的版本）时，您实际上可以执行以下操作：

  cd hello.c @@ 
目录
  

这将列出所有唯一标签供您选择。

How to copy an element or file from Clearcase with a particular label, without applying that label in config specs.

I don't want to change the config spec of my view, but I need to access an older version of one of my selected files, and I would like to do so directly from my existing view (again, without changing anything).
I know the version I want to restore (from instance version 2, even though I am selecting currently version 3 in my view).

What cleartool command would you use in order to access said old version?

解决方案

You can use the extended pathname, but only using a dynamic view (any existing dynamic view, not particular config spec required).
The article "To open a version not currently in your view from a command prompt using a version-extended path" mentions that you can use a snapshot view too, but you would need for:

• the element to be already loaded (obviously not at the version you want)
• the old version to be copied into the view (as a private file): cleartool get -to prog.old.c prog.c@@/main/r1_fix/1

Note that the contextual menu of a version tree includes a "Send To" entry which would effectively do the cleartool get (i.e. the copy) for you.

But in a dynamic view, you don't need to copy anything, you can directly reference any old version:

cp foo.c@@/RLS4.3
cp include.h@@/main/bugfix/REL2 

See also version selector:

If a version label was defined to be one-per-element, an additional link/file system object appears at the top level of an element's directory tree.
For example, if BL3 is a one-per-element label, these version-extended pathnames are both unambiguous references to the same version:

hello.c@@/BL3
hello.c@@/main/bugfix/patch2/BL3

In effect, this feature allows you to reference a version without knowing its exact location in the version tree.

In a dynamic view, when you see hello.c in your view (and that can be any selected version, not the one you want with the label), you actually can do:

cd hello.c@@
dir

That will list all the unique labels for you to choose from.
