CHANGELOG

2021.07.30

  • Force system transport ssh connections to allocate a tty (-tt); fixes issue that would prevent system transport from sending any command > 1024 chars.
  • Added use_compressed_parser argument to the driver constructor -- defaults to True which means we "squish" all the whitespace out of any input we get from the user before sending it to the netconf server, generally this is no problem, but some devices (looking at you NX-OS!) lock up and stop reading at some character counts (4096 in NX-OS it seems) causing the connection to timeout and die. By not "squishing" whitespace out this does not happen.
  • Fixed some typing issues and pinned to scrapli pre-release to take advantage of updated typing/packaging setup
  • Deprecate filters argument on get_config -- will be supported (by decorator) until 2022.01.30 (and pre-releases). This was done to make the arguments consistent for get, get_config, and rpc.
  • Better handling of multiple filter elements in a filter string
  • Smarter message building -- previously most of the final bytes payload that we send to the servers got built in the base driver class, and then some more (1.1 encoding) got added in the channel base class -- silly! Fixed this, so it is all done in the driver which eliminated a bunch of duplication (yay!).
  • Deprecating comms_ansi -- see also scrapli changelog for this release (2021.07.30) for more details. This was never used here in scrapli_netconf so should be a non issue, but will not be fully deprecated until 2022.01.30.
  • Re-fix #10... see #68 -- now there is a test with a comment so I don't break this again :)
  • Added copy_config method, thanks to Roman Dodin for adding this in scrapligo first!
  • Added handling/warning about use_compressed_parser if we catch a timeout exception when looking for prompt after writing inputs -- since I don't know (can't know?) which platforms may require this flag set to False this seems like a reasonable way to let users know and point them in the right direction to get things working!
  • Reswizzled the echo check to be like the scrapligo version -- much simpler/less moving parts, so should be good!

2021.01.30

  • Big overhaul in line with the scrapli core overhaul... mostly this was about reconciliation of the channel and transport things and putting stuff where it should have been in the first place... see the changelog at scrapli core for much more details
  • FUTURE BREAKING CHANGE -- NetconfScrape and AsyncNetconfScrape have been renamed to NetconfDriver and AsyncNetconfDriver -- there are alias classes so you can continue to use NetconfScrape and AsyncNetconfScrape but there is a warning, and these will be removed at some point in the future!

2021.01.17

  • Support for future "vrouter" setup for testing
  • Flatten all channel inputs (no pretty printed xml) -- seems to behave much more nicely across the board!
  • Updated test to match some recent scrapli core updates (multipl easync transports)

2020.11.15

  • Support namespaces in hello messages -- primarily to support "rfc-compliant" mode in JunOS -- thank you Gary Napier for finding this and coming up with the fix!
  • Another fixup to chunk checker -- think that the itty bitty chunk issues have now been solved :)

2020.10.24

  • Improve the "echo" checker -- and add this for sync as well, because...
  • SSH2 and Paramiko are now supported transports!
  • As part of the "improved echo checker" sync channel now also overrides the read_until_input method like the async channel does -- again, for the same reasons.
  • All transports minus system are now optional extras -- this means that asyncssh is no longer an install requirement
  • As expected with above point -- added optional extras install options in setup.py as well as a "full" option just like scrapli core
  • MAYBE BREAKING CHANGE: shouldn't be an issue for 99.9999% of people, however, the asyncssh transport is no longer imported and available in the transport package
  • Add error_messages attribute to response object -- initialized as an empty list and the text of any rpc-error/error -message fields are placed into this list if there are any in the response from the server
  • Improve netconf 1.1 chunk matching regex to not ignore/chop off Nokia error messages that contained # symbols

2020.10.10

  • Handle netconf 1.1 devices that have chunk sizes of 1
  • Ensure results are "pretty printed"
  • Above two items were worked out with thanks to Hugo Tinoco! PS - this has been tested on Nokia devices now too!
  • Hopefully improved asyncssh "echo checker" (see _check_echo) method in async_channel for details
  • Update CI to use 3.9 instead of 3.9-dev (and update deprecated set-env)
  • Remove transport session locks

2020.09.23

  • Strip server capabilities so we don't save capabilities with newlines/whitespace
  • Add validate and delete_config methods

2020.09.18

  • Fix some pins for dev requirements
  • Add 3.9-dev to actions
  • Fix scrapli-asycnssh not in setup.py install_requires
  • Retest everything! In general, just get this updated/ready for nornir-scrapli!

2020.07.26

  • Update to match scrapli core -- moved to updated timeout decorator, fixed a test to match a better exception message

2020.07.12

  • Minor improvements to response recording (should be a tick faster)
  • Update decorators for async things to use the improved async_operation_timeout in scrapli 2020.07.12
  • Set strip_namespaces to False for AsyncNetconfScrape for consistency/sanity
  • Update a few dev pins, update required pins to ensure no major lxml updates break things

2020.07.04

  • First real release??? :)

2020.04.19

  • Initial pypi release... very beta still
