Ordering promises

This counts to five by default. If we change ‘/bin/echo one’ to ‘/bin/echox one’, then the command will fail, causing us to skip five and go to six instead.

This shows how dependencies can be chained in spite of the order of promises in the bundle.

Normally the order of promises in a bundle is followed, within each promise type, and the types are ordered according to normal ordering.

body common control
{
      bundlesequence => { "order" };
}

bundle agent order
{
  vars:
      "list" slist => { "three", "four" };

  commands:
    ok_later::
      "/bin/echo five";

    otherthing::
      "/bin/echo six";

    any::

      "/bin/echo one"     classes => d("ok_later","otherthing");
      "/bin/echo two";
      "/bin/echo $(list)";

    preserved_class::
      "/bin/echo seven";
}

body classes d(if,else)
{
      promise_repaired => { "$(if)" };
      repair_failed => { "$(else)" };
      persist_time => "0";
}

Aborting execution

body common control
{
      bundlesequence  => { "testbundle"  };
      version => "1.2.3";
}

body agent control
{
      abortbundleclasses => { "invalid.Hr16" };
}

bundle agent testbundle
{
  vars:
      "userlist" slist => { "xyz", "mark", "jeang", "jonhenrik", "thomas", "eben" };

  methods:
      "any" usebundle => subtest("$(userlist)");
}

bundle agent subtest(user)
{
  classes:
      "invalid" not => regcmp("[a-z][a-z][a-z][a-z]","$(user)");

  reports:
    !invalid::
      "User name $(user) is valid at 4 letters";
    invalid::
      "User name $(user) is invalid";
}
