Ansible blockinfile oddity
I was reading Ansible's blockinfile sources for, uhm, reasons, and the code flow looked a bit odd.
So I checked what happens if a file has spurious block markers.
Give this file:
$ cat /tmp/test.orig
line0
# BEGIN ANSIBLE MANAGED BLOCK
line1
# END ANSIBLE MANAGED BLOCK
line2
# END ANSIBLE MANAGED BLOCK
line3
# BEGIN ANSIBLE MANAGED BLOCK
line4
And this playbook:
$ cat test.yaml
---
- hosts: localhost
tasks:
- name: test blockinfile
blockinfile:
block: NEWLINE
path: /tmp/test
You get this result:
$ cat /tmp/test
line0
# BEGIN ANSIBLE MANAGED BLOCK
line1
# END ANSIBLE MANAGED BLOCK
line2
# BEGIN ANSIBLE MANAGED BLOCK
NEWLINE
# END ANSIBLE MANAGED BLOCK
line4
I was hoping that I was reading the code incorrectly, but it turns out that Ansible's blockinfile matches the last pair of begin-end markers it finds, in whatever order it finds them.
