CLI already provides a pager() method that feeds $PAGER on stdin, so we
just feed that the plaintext from the vault file. We can also eliminate
the redundant and now-unused shell_pager_command method in VaultEditor.
Since c8f2483d, ini.py expects to always be passed in a pre-created list
of groups, and can no longer deal sensibly with an empty list; this just
makes that expectation clear.
This fixes a corner case where ini files live in a subdir
of the main inventory directory.
Reproducing the original error:
mkdir -p inventory/ini
cat > inventory/ini/hosts << EOF
[www]
www1
EOF
$ ansible -i inventory/ all -m ping
ERROR! 'all'
(or without the [www] group, it would complain about 'ungrouped')
Fixes another failing test.
(I don't want to do a global search/replace for 'basestring' because I
want to have unit tests covering each occurrence. When I run out of
existing failing tests, I'll try to write new ones.)
* Remove extraneous imports
* Fix some error handling
* Enable pipelining
* Disable su since it doesn't work
* Add error message when installed docker is not recent enough to
support this plugin
* Move nested functions to class level
* Make transport a class attribute
* Make exec_command, put_file and fetch_file more robust
* Disable su as it's not currently working 100% (and was disabled in v1).
* Move BUFSIZE out of the class to match other conenction plugins
* _connect shouldn't return self.
This is also peripheral to what _build_command needs, can be improved
and tested independently, and so makes more sense in a separate method.
This commit doesn't change any functionality (and I've verified that it
works with the various combinations: control_path set in ansible.cfg,
ssh_args adding or not adding ControlMaster/ControlPersist, etc.).
SSH pipelining can be a significant performance improvement, but it will
not work if sudoers is configured to requiretty. With this change, one
could have pipelining enabled in ansible.cfg, but use sudo to turn off
requiretty in a separate play (or task) where pipelining is disabled:
- hosts: foo
vars:
ansible_pipelining: no
tasks:
- lineinfile: dest=/etc/sudoers line='Defaults requiretty' state=absent
sudo_user: root
(Note that sudoers has a complicated syntax, so the above lineinfile
invocation may be too simplistic for production use; but the point is
that a separate play can do something to disable requiretty.)
Also get pipelining working for people who look to chroot as an example
for their own connection plugins
Note: In the latest v2 API, action handles become but chroot doesn't
reliably handle become. Maybe we need to add a has_become attribute
that the action can display an appropriate error.
