unicon	v19.7

Upgrade Instructions

bash$ pip install --upgrade unicon

Features and Bug Fixes:

• core

  • fix StateTransition do_transitions to return correct output

  • fix dialogs with multi thread to send command to correct connection

  • inherit base Connection from Lockable and add RLock for BaseService

  • improve performance by enhancing pty_backend to support different modes in match_buffer. By default, match_mode_detect is enabled. Detect rules are as below:

    • search whole buffer with re.DOTALL if:

      • pattern contains any of: \r, \n

      • pattern equals to any of: .*, ^.*$, .*$, ^.*, .+, ^.+$, .+$, ^.+

    • Else if pattern ends with $, will only match last line

    • In other situations, search whole buffer with re.DOTALL

  • improve performance by compiling regex patterns first in dialog_processor

  • improve performance by removing re.search again in truncate_trailing_prompt

  • add connection “host” in SSHTunnel and topology adapter

• added credential support

  • When pyATS integration is used,

    • If a default credential is supplied, then a credential of any other name is looked up explicitly and is not found, the default credential is used instead.

    • credentials supplied to the connection contain any credentials defined at the device and testbed levels as well.

  • If one or more credentials are supplied:

    • The tacacs and passwords pyATS testbed keys are ignored.

    • Use of any of the following unicon.Unicon.Connection arguments cause a deprecation warning to be raised :

      • username

      • password

      • enable_password

      • tacacs_password

      • line_password

    • The following credential names are expected to be defined explicitly:

      • enable : This credential defines the password to be sent when bringing routing devices to their enable mode.

      • sudo : The fsos/ftd plugin expects this credential to contain the sudo password.

      • ssh : When setting up an sshtunnel against a server specified in a pyATS testbed servers block, this credential must be defined against that server block.

    • The login_creds argument (specified either in pyATS connection block or as a unicon.Unicon.Connection parameter), now controls the order credentials are applied when username/password prompts are received while connecting to the device.

    • The prompts/login and prompts/password parameters are now expected to be explicitly set in the pyATS connection block or as unicon.Unicon.Connection parameters.

    • The switchover service now accepts a switchover_creds parameter that allows users to define what credentials to use should a username or password prompt occur during switchover.

    • The reload service now accepts a reload_creds parameter that allows users to define what credentials to use should a username or password prompt occur during reload.

  • The execute service no longer responds to username/password requests, users are expected to pass in their own dialog if this kind of handling is required.

• generic plugin

  • add flatten_splitlines_command method in generic utils to flatten commands

  • add get_handle method in BaseService for all services to reuse

  • add bulk argument for Configure service to send commands in one sendline

  • refactor generic Configure service, and now HaConfigureService inherits from Configure

  • fix several bugs in BaseService and generic HaExecService

• iosxr plugin

  • fix potential bugs in iosxr execute and configure related services

  • add HaAdminExecute and HaAdminConfigure services for iosxr

  • fix asr9k plugin services admin_execute, admin_configure and admin_bash_console on 64-bit asr9k

  • added dual RP support to iosxr/spitfire plugin.

• junos plugin

  • fix junos plugin configure service

• nxos plugin

  • added VDC related robot commands.

• asa plugin

  • added warning to ASA plugin patterns.

• ios plugin

  • added vrf support in ios plugin ping service. It now accepts vrf as input and passes it as part of the ping command
