CFE 语法错误

Question

尝试编写一个 cfengine3 承诺，它将获取整个目录并将其下移一级。

我已经使用我的政策中心来分发承诺，但我还没有将它折叠到我的活动中 promise.cf

这是承诺：

body common control

{

        bundlesequence => { dirstructure };
}


#Find out by existance of directories if filesystem is old structure or new
#Set classes for each instance. If old, copy down one level.
#If new file system already, pat yourself on the back

bundle agent dirstructure
{     
classes:

    "oldFILEstructure"expression => isdir("/old/dir/structure/");
    "newFILEstructure" expression => isdir("/new/dir/structure/");


reports:

    oldFILEstructure::
        "system has old file structure..";
    newFILEstructure::
        "system has new file structure..";

methods:
    oldFILEstructure::
        "migratedirectories" usebundle => movedirectories
}

bundle agent movedirectories

{
files:
        "/new/dir/"

        copy_from => local_cp ("/old/dir/structure/.");
        depth_search => recurse ("inf");
}

我已将 this "isdir" source and this example 用于 local_cp，两者均来自 CFE，以此作为承诺的基础。调用时，我得到以下错误输出，我试图找出原因。

:/var/cfengine/inputs/standalone# cf-agent --no-lock --inform --file ./file_structure.cf

depth_search => recurse ("inf");
           ^

depth_search => recurse ("inf");
           ^

depth_search => recurse ("inf");
              ^

depth_search => recurse ("inf");
                      ^

depth_search => recurse ("inf");
                        ^
./file_structure.cf:41:31: error: Expected ';', got ')'
depth_search => recurse ("inf");
                              ^
./file_structure.cf:41:32: error: Expected promiser string, got ';'
depth_search => recurse ("inf");
                               ^
./file_structure.cf:42:1: error: Expected ';', got '}'
}

Answer 1

files:
        "/new/dir/"

        copy_from => local_cp ("/old/dir/structure/.");
        depth_search => recurse ("inf");
}

您在 copy_from 行的末尾多了一个分号。

分号 ; 表示承诺的结束。尝试将 copy_from 行末尾的分号切换为逗号 ,.

files:
        "/new/dir/"

        copy_from => local_cp ("/old/dir/structure/."),
        depth_search => recurse ("inf");
}

此外，您可能需要查看 transformer 属性。它可能适合也可能不适合您的情况。\

bundle agent example
{
    files:
      "/old/dir/structure" -> { "jira:EXAMPLE-1234" }
        transformer => "/bin/mv /old/dir/structure /new/dir/structure",
        comment => "The standard is to use the new location because x, y, z. Bad thing Q or U might happen if this is not managed properly.";
}
