made in PR #24431
* Fix py3 prompt issue for invalid show command
* Fix review comments
* Add generic fix for error prompt in py3
* Fix CI issue
* Fix network_cli unit test failure
Fix for persistent connection plugin on Python3. Note that fixes are also needed to each terminal plugin. This PR only fixes the ios terminal (as proof that this approach is workable.) Future PRs can address the other terminal types.
* On Python3, pickle needs to work with byte strings, not text strings.
* Set the pickle protocol version to 0 because we're using a pty to feed data to the connection plugin. A pty can't have control characters. So we have to send ascii only. That means
only using protocol=0 for pickling the data.
* ansible-connection isn't being used with py3 in the bug but it needs
several changes to work with python3.
* In python3, closing the pty too early causes no data to be sent. So
leave stdin open until after we finish with the ansible-connection
process.
* Fix typo using traceback.format_exc()
* Cleanup unnecessary StringIO, BytesIO, and to_bytes calls
* Modify the network_cli and terminal plugins for py3 compat. Lots of mixing of text and byte strings that needs to be straightened out to be compatible with python3
* Documentation for the bytes<=>text strategy for terminal plugins
* Update unittests for more bytes-oriented internals
Fixes#24355
* fixes error where eos would close the cli shell
* fixes network_cli connection plugin to check before calling open_shell()
* fixes json commands being sent over eapi
* removes unneeded supports_multiplexing var
* refactors terminal_prompts_re to terminal_stdout_re
* refactors terminal_errors_re to terminal_stderr_re
* updates network_cli unit test cases
The network_cli plugin would return immediately if an error was
detected. This patch will force the connection plugin to still try to
detect the current prompt even if an error is found.
* refactors supports_sessions to a property
* exposes supports_sessions as a toplevel function
* adds open_shell() to network_cli
* implements open_shell() in eos action plugin
* removes unused code
* removes module_utils/local.py
* removes plugins/action/network.py
* removes action_handler from connection plugins
* removes code to use action_handler in task_executor
* updates action plugins to subclass from normal
* checks if signal hander is set and sets it if not (will be set if coming
from ansible-connection)
* will now timeout long running commands based on DEFAULT_TIMEOUT setting
In some cases it is desirable to have a send only function that doesn't
wait for the response from the CLI (such as reloading a device). This
adds a new key to the command json string sendonly that will
achieve this behavior.
Connection plugin can define default action plugin to use by providing
action_handler instance variable. This will override the default
action plugin normal
This adds back the change to the network_cli plugin. Ths change adds
the ensure_connect decorator to the open_shell() method to make sure
the connection is valid before trying to open a shell.
The issue was due to the addition of the decorator that will call
_connect() when there is no connection. The _connect() method should
have been mocked in the test case. This commit fixes the test
case as well
Change was originally reverted in c414ded69a
* removes superfluous timeout kwargs from open_shell()
* cleans up play_context become check
* adds check for ssh session and calls _connect() if needed
This updates the network_cli connection plugin to attempt to automatically
determine the remote device os. The device network os discovery can
be overridden by setting the ansible_network_os value.
* adds new connection plugin `network_cli` which builds on paramiko
* adds new plugin `terminal` used for manipulating network_cli terminals
* adds new field to play_context `network_os` settable as ansible_network_os
This commit adds the plugins necesary to establish a persistent cli connection
to network devices of ssh. It builds on the paramiko connection plugin
to create a shell environment that will persistent through ansible-connection.
The `newtork_cli` plugin then uses the network_os in the instance of
PlayContext to load the appropriate network OS environment plugin for
handling opening and closing of shells as well as privilege escalation.
