This was commented out earlier because of the lack of interprocess
locking and prepare_writeable_dir in v2.
The locking was not needed: it could only protect against other siblings
of this process (since they were all locking a temporary file that was
opened in the parent), and those would be running as the same user and
with the same umask. Also, os.makedirs() tolerates intermediate paths
being created by other processes. For any other kind of error, both
locking and non-locking code paths would fail in the same way.
So all we really need to do is make sure we have write permissions.
(We also move the cp_dir handling code to where we actually set the
ControlPath ourselves; if the user has set it via ssh_*args already,
we don't need to bother.)

Don't disable GSSAPI/Pubkey authentication when using --ask-pass
This commit is based on a bug report and PR by kolbyjack (#6846) which
was subsequently closed and rebased as #11690. The original problem was:
«The password on the delegated host is different from the one I
provided on the command line, so it had to use the pubkey, and the
main host doesn't have a pubkey on it yet, so it had to use the
password.»
(This commit is revised and included here because #11690 would conflict
with the changes in #11908 otherwise.)
Closes#11690

Be more explicit about why SSH arguments are added
This adds vvvvv log messages that spell out in detail where each SSH
command-line argument is obtained from.
Unfortunately, we can't be sure if, say, self._play_context.remote_user
is obtained from ANSIBLE_REMOTE_USER in the environment, remote_user in
ansible.cfg, -u on the command line, or an ansible_ssh_user setting in
the inventory or on a task or play. In some cases, e.g. timeout, we
can't even be sure if it was set by the user or just a default.
Nevertheless, on the theory that at five v's you can use all the hints
available, I've mentioned the possible sources in the log messages.
Note that this caveat applies only to the arguments that ssh.py adds by
itself. In the case of ssh_args and ssh_extra_args, we know where they
are from, and say so, though we can't say WHERE in the inventory they
may be set (e.g. in host_vars or group_vars etc.).

Add a FAQ entry about ansible_ssh_extra_args

Allow ansible_ssh_args to be set as an inventory variable
Before this change, ssh_args could be set only in the [ssh_connection]
section of ansible.cfg, and was applied to all hosts. Now it's possible
to set ansible_ssh_args as an inventory variable (directly, or through
group_vars or host_vars) to selectively override the global setting.
Note that the default ControlPath settings are applied only if ssh_args
is not set, and this is true of ansible_ssh_args as well. So if you want
to override ssh_args but continue to set ControlPath, you'll need to
repeat the appropriate options when setting ansible_ssh_args.
(If you only need to add options to the default ssh_args, you may be
able to use the ansible_ssh_extra_args inventory variable instead.)

Allow overriding ansible_ssh_extra_args on the command-line
This patch makes it possible to do:
ansible somehost -m setup \
--ssh-extra-args '-o ProxyCommand="ssh -W %h:%p -q user@bouncer.example.com"'
This overrides the inventory setting, if any, of ansible_ssh_extra_args.
Based on a patch originally by @Richard2ndQuadrant.

Add an ansible_ssh_extra_args inventory variable
This can be used to configure a per-host or per-group ProxyCommand to
connect to hosts through a jumphost, e.g.:
inventory:
[gatewayed]
foo ansible_ssh_host=192.0.2.1
group_vars/gatewayed.yml:
ansible_ssh_extra_args: '-o ProxyCommand="ssh -W %h:%p -q bounceuser@gateway.example.com"'
Note that this variable is used in addition to any ssh_args configured
in the [ssh_connection] section of ansible.cfg (so you don't need to
repeat the ControlPath settings in ansible_ssh_extra_args).
Replace .iteritems() with six.iteritems() everywhere except in
module_utils (because there's no 'six' on the remote host). And except
in lib/ansible/galaxy/data/metadata_template.j2, because I'm not sure
six is available there.
The lock file is (a temporary file) opened in the parent process, whose
open fd is inherited by the workers after fork, and passed down through
the PlayContext. Connection grows lock/unlock methods which can be used
by individual connection plugins.
Right now, we don't do any locking, but we still scan known_hosts files
twice per connection. That's completely unnecessary, and the proposed
solutions to the locking problem wouldn't need known_hosts scanning
anyway, so this code can go away.
* Add exception handling when running PowerShell modules to provide exception message and stack trace.
* Enable strict mode for all PowerShell modules and internal commands.
* Update common PowerShell code to fix strict mode errors.
* Fix an issue with Set-Attr where it would not replace an existing property if already set.
* Add tests for exception handling using modified win_ping modules.
We can unconditionally wrap remote_addr in square brackets for scp and
sftp (both of which require them for IPv6 addresses), but not wrap them
at all for ssh (which doesn't accept them). This way, we don't have to
detect and treat IPv6 addresses specially. This works for hostnames,
IPv4 addresses, and IPv6 addresses.
The earlier code seemed to intend to wrap all IPv6 addresses in square
brackets, which would have broken ssh, but it actually made no attempt
to detect IPv6 addresses at all (so it broke only with IPv6 addresses
for scp and sftp).
Based on a review of PR #11677 by @JuiceBoxSingularity
- Add support for inserting module args into PowerShell modules. Fixes#11661.
- Support Windows paths containing spaces. Applies changes from #10727 to v2. Fixes#9999. Should also fixansible/ansible-modules-core#944 and ansible/ansible-modules-core#1007.
- Change how execution policy is set for running remote scripts. Applies changes from #11092 to v2. Also fixesansible/ansible-modules-core#1776.
- Use codepage 65001 (UTF-8) for WinRM connection instead of default (CP437), convert command to UTF-8 and results from UTF-8. Replaces changes from #10024. Fixes#11198.
- Close WinRM connection when task completes.
- Use win_stat, win_file and win_copy modules instead of stat, file and copy when called from within other action plugins (only when using WinRM+PowerShell).
- Unquote Windows path arguments before passing to win_stat, win_file, win_copy and slurp modules (only when using WinRM/PowerShell).
- Check for win_ping module to determine if core modules are missing (only when using WinRM/PowerShell).
- Add stdout_lines to result from running low level commands (so stdout_lines is available when using raw/script).
- Update copy action plugin to use shell functions for joining paths and checking for trailing slash.
- Update fetch action plugin to unquote source path when using Windows paths.
- Add win_copy and win_template action plugins that inherit from copy and template.
- Support running .bat and .cmd scripts using default system encoding instead of UTF-8.
- Always send PowerShell commands as base64-encoded blobs to allow for running simple PowerShell commands via raw.
- Support running modules on Windows with interpreters other than PowerShell.
- Update integration tests to support above changes and test unicode fixes.
- Add test for win_user error from ansible/ansible-modules-core#1241 (fixed by ansible/ansible-modules-core#1774).
- Add test for additional win_stat output values (implemented by ansible/ansible-modules-core#1473).
- Add test for OS architecture and name from setup.ps1 (implemented by ansible/ansible-modules-core#1100).
All WinRM integration tests pass for me with these changes.
Fixes an issue with a confusing error: "paramiko: The authenticity of host '[host]' can't be established" when ssh on the command line doesn't complain
Closes PR #7730
* Don't reference __class__ when we can use the instance itself
* use isdisjoint() as it can stop once a match is found
* Remove a condtional that was taken care of in the conditonal just above
* enable batch mode (configurable with a config option, on by default)
for sftp transfers, so we can catch errors more easily
* general cleanup in the local connection plugin and fetch action plugin
Fixes#11612
Also making PlayContext a child class of the Playbook Base class,
which gives it access to all of the FieldAttribute code to ensure
field values are correctly typed after post_validation
Fixes#11381
Moving the make_sudo_cmd() calls back up to the action level so that connection
plugins don't have to know about it at all, and moving some of the become data
(prompt and success_key) into the ConnectionInformation object so they don't
need to be passed around needlessly.
