Ansible multiple包含多个任务？

我有一个Ansible playbook，它包含一个文件两次，并传入一个参数以更改行为：

site.yml:

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

include文件仅打印参数值：

test.yml:

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

清单文件设置为在本地主机上运行：

库存：

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

结果就是我所期望的，include文件运行两次，一次是parm=AAA，一次是parm=BBB：

>ansible-playbook -i inventory site.yml

PLAY ***************************************************************************

TASK [setup] *******************************************************************
ok: [localhost]

TASK [include parm=AAA] ********************************************************
included: test.yml for localhost

TASK [debug msg=dbg 1 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 1 AAA"
}

TASK [include parm=BBB] ********************************************************
included: test.yml for localhost

TASK [debug msg=dbg 1 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 1 BBB"
}

PLAY RECAP *********************************************************************
localhost                  : ok=5    changed=0    unreachable=0    failed=0   

太好了。现在，我需要在include文件中执行第二个任务：

test.yml:

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

我所期望的是，include文件将像以前一样执行两次，首先执行原始的“dbg1aaa”任务，然后执行新的“dbg2aaa”任务，然后执行原始的“dbg1bbb”任务，然后执行新的“dbg2bbb”任务

而是这样做的：

>ansible-playbook -i inventory site.yml

PLAY ***************************************************************************

TASK [setup] *******************************************************************
ok: [localhost]

TASK [include parm=AAA] ********************************************************
included: test.yml for localhost

TASK [debug msg=dbg 1 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 1 AAA"
}

TASK [debug msg=dbg 2 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 2 AAA"
}

PLAY RECAP *********************************************************************
localhost                  : ok=4    changed=0    unreachable=0    failed=0   

它跳过了第二个包含。我认为多次包含同一个文件可能有问题，因此我用新名称复制了包含文件：

test2.yml:

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

并将剧本调整为包含以下内容：

site.yml:

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

然后，如果test.yml只有一个任务，我会得到预期的结果：

PLAY ***************************************************************************

TASK [setup] *******************************************************************
ok: [localhost]

TASK [include parm=AAA] ********************************************************
included: test.yml for localhost

TASK [debug msg=dbg 1 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 1 AAA"
}

TASK [include parm=BBB] ********************************************************
included: test2.yml for localhost

TASK [debug msg=dbg 1 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 1 BBB"
}

TASK [debug msg=dbg 2 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 2 BBB"
}

PLAY RECAP *********************************************************************
localhost                  : ok=6    changed=0    unreachable=0    failed=0   

但如果test.yml有两个任务，它将跳过第二个任务，包括：

PLAY ***************************************************************************

TASK [setup] *******************************************************************
ok: [localhost]

TASK [include parm=AAA] ********************************************************
included: test.yml for localhost

TASK [debug msg=dbg 1 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 1 AAA"
}

TASK [debug msg=dbg 2 {{ parm }}] **********************************************
ok: [localhost] => {
    "changed": false, 
    "msg": "dbg 2 AAA"
}

PLAY RECAP *********************************************************************
localhost                  : ok=4    changed=0    unreachable=0    failed=0   

我错过了什么？没有错误或失败，include文件中的两行几乎相同。为什么在第一个包含文件中有多行会导致跳过第二个包含

如果我在剧本中添加更多调试行：

site.yml:

---
- tasks:
  - include: test.yml parm=AAA
  - include: test.yml parm=BBB

- debug: msg="dbg 1 {{ parm }}"

localhost ansible_connection=local

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

- debug: msg="dbg 1 {{ parm }}"
- debug: msg="dbg 2 {{ parm }}"

---
- tasks:
  - include: test.yml parm=AAA
  - include: test2.yml parm=BBB

---
- tasks:
  - include: test.yml parm=AAA
  - debug: msg="1"
  - include: test2.yml parm=BBB
  - debug: msg="2"
  - debug: msg="3"

只有在调试消息前面的include文件只有一行时，才会输出调试消息

我正从git://github.com/ansible/ansible.git devel分支，在测试之前立即更新。

问题首先出现在git中

优化导致了问题。

我建议将此作为核心项目的一个问题归档。在2.0中，动态任务队列的include有很多更改，这听起来像是一个合法的bug。

这是一个bug，但他们现在已经修复了。
