unable to evaluate conditional

[fanvalt]

Hello,

I don't understand where I am doing wrong in this simple tasks:

- name: Search for bin directory

  stat:

    path: /{{ Directoryname }}/{{ item }}/bin

  register: previous

  with_items: "{{ shr4you_inst.stdout_lines }}"

  when: shr4you_inst|success

- debug: msg="previous {{previous}}"

- name: stop karaf

  shell: chdir={{ previous.stat.path }} ./stop

  async: 5

  poll: 5

  ignore_errors: True

  when: previous.stat.isdir

The last When: condition is ALWAYS running with this error: "The error was: unable to evaluate conditional: previous.stat.isdir"

Here is the logfile:

TASK [4YOU : Search for bin directory] **************************************

ok: [integuno] => (item=SHR_4YOU-hra-1.1.0-SNAPSHOT)

}

Thanks for your help,

if I add 2 debug tasks this way , it seems the previous.stat is not defined anymore.

- debug: msg="previous {{previous}}"

- debug: msg="previous isdir {{previous.stat.isdir}}"

- debug: msg="previous path {{previous.stat.path}}"

TASK [4YOU : debug] ************************************************************

ok: [integuno] => {

    "msg": "previous {'msg': u'All items completed', 'changed': False, 'results': [{u'stat': {u'uid': 54322, u'exists': True, u'woth': False, u'mtime': 1472557536, u'inode': 21695026, u'isgid': False, u'size': 4096, u'wgrp': False, u'isuid': False, u'isreg': False, u'pw_name': u'integuno', u'gid': 54323, u'ischr': False, u'wusr': True, u'xoth': True, u'rusr': True, u'nlink': 2, u'issock': False, u'rgrp': True, u'gr_name': u'hr', u'path': u'/integuno/DV70_EX/SHR_4YOU-hra-1.1.0-SNAPSHOT/bin', u'xusr': True, u'atime': 1472557622, u'isdir': True, u'ctime': 1472634055, u'isblk': False, u'xgrp': True, u'dev': 64768, u'roth': True, u'isfifo': False, u'mode': u'0755', u'islnk': False}, u'changed': False, '_ansible_no_log': False, '_ansible_item_result': True, 'item': u'SHR_4YOU-hra-1.1.0-SNAPSHOT', 'invocation': {'module_name': u'stat', u'module_args': {u'checksum_algorithm': u'sha1', u'mime': False, u'get_checksum': True, u'follow': False, u'path': u'/integuno/DV70_EX/SHR_4YOU-hra-1.1.0-SNAPSHOT/bin', u'get_md5': True}}}]}"

}

TASK [4YOU : debug] ************************************************************

ok: [integuno] => {

    "msg": "previous isdir {{previous.stat.isdir}}"

}

TASK [4YOU : debug] ************************************************************

ok: [integuno] => {

    "msg": "previous path {{previous.stat.path}}"

Any idea ?

It very hard to read the output using debug this way, please use this
instead
- debug: var=previous

If you do you probably will see what's happening a lot easier.

When you use register with with_items the result back is a list.

I finally found out how to solve this but I don't understand why.

I had to use the following syntax to use the register variable, even if the register variable was not containing an "_" in its name:

- debug: msg="previous {{previous}}"

- debug: msg="previous isdir {{previous.results[0].stat.isdir}}"

- debug: msg="previous path {{previous.results[0].stat.path}}"
