Fixes#38732
Make matching leading newline for cli prompt
optional as there are cases when returned repsonse
for ios/iosx remote host doesn't have newline before
cli prompt.
* Handle multiple sub prompts for network_cli connection
Fixes#35349
* Check if the same prompt is repeated in consecutive window
if it is repeated it indicates there is problem with answer
provided
* In that case report error to user
* Fix CI failure
* Fixes#35349
* Add prompt_retry count to control max number of times
to expect the same prompt before it error's out
* Make required changes in ios and eos terminal plugin to handle
wrong enable password correctly and return proper error
message to user.
* Check if the same prompt is repeated in consecutive window
if it is repeated it indicates there is the problem with an answer
provided
* In that case report error to user
* Look for password prompts at the beginning of the line only
* Adds secondary checks for the supplied sub-prompts
Handles the case for enable prompts where enable_pass may be incorrect
and the deivce is still prompting for the password
* Fixes a prompt doubling issue that impacted missing ios enable password prompts.
Due to get_prompt sending a '\n' the prompts became doubled and out-of-sync with what
was expected. This caused the enable command prompts to be missed.
Also added verification that on_become succeeded to reach enable prompt.
* Moved prompt doubling comment per shippable
* Update connection play_context when socket exists
* Don't fail on connections other than network_cli
* Fix enable prompt detection on ios & eos
* Check against "Module not found" error code, defined in modules/jsonrpc.py
Turns out in some commands, like 'sh bgp summary' a line containing
'Not found' can be shown as a column.
This causes those commands to error out with RC=1 .
Fixes#26577
* Add ios changes for Python3
Make `execute_command` arguments and its
return value complaint to PY3 changes
made in PR #24431
pep8 fixes
* Fix CI issues
* Fix review comment
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
We have a list of specific messages that we scree-scrape and flag
them as legit errors.
However, we also have a catch-all regex that matches everything
starting with %.
That can cause issues on commands that return lines with that
character, like for example the 'crypto key generate'.
Fixes#23770
* 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
For devices that do not support mutliplexing, we cannot automatically
determine the network os. This removes the os guess static method
from the terminal plugin. For this devices, the network_os
value must be configured
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.
