v24.0

New Features in 24.0

• When invoking tests with pytest, the --log-(cli|file)-(level|format)
  command line arguments and their corresponding pytest.ini configure options
  are now respected (making it possible to have different format and logging
  levels in the log file than then console).
• A new log level called CONSOLE has been added between the default
  INFO and DEBUG levels. This level will show all reads and writes made
  to the serial console during testing.
• The docker support was extended to support buildx, allowing the build of arm64
  container images.
• The tool lookup function has been extended to return the original name in case
  the path can't be found. This makes specification of the qemu binary easier to
  use.
• The bindings base class has been extended, allowing the user to retrieve
  all resources used by a driver.
• Support for STLink V2 was added.
• UBootStrategy was extended with a force() function.

  fully qualified domain name instead of the hostname.
• The QEMUDriver now has an additional disk_opts property which can be
  used to pass additional options for the disk directly to QEMU
• All drivers now inherit a logger from the Driver base class and many
  drivers were changed to use this logger.
• The new poe_mib backend allows switching of power over Ethernet-capable
  ports on switches that use the corresponding SNMP MIB.

Bug fixes in 24.0

• The pypi release now uses the labgrid pyserial fork in the form of the
  pyserial-labgrid package. This fixes installation with newer versions
  of pip.
• Several tests have gained an importorskip() call to skip them if the
  module is not available.

• Fix named SSH lookups in conjunction with an environment file in
  labgrid-client.
• The crossbar virtual-environment now needs to be separate from the labgrid
  environment, for more information please consult the current documentation <https://labgrid.readthedocs.io/en/latest/getting_started.html#coordinator>_.
• The markers now are restricted to patterns which won't match WARN,
  ERROR, INFO and similar log notifiers.
• A race inside the SSHDriver cleanup has been fixed.
• The labgrid-client monitor command now outputs the full resource identifier.
• Many of the USB loader commands e.g. imx-usb-loader will now print to the
  console when logging is not enabled.

• Instead of using a private member on the pytest config, the labgrid plugin now
  uses the pytest config stash.
• The ShellDriver was fixed to set the correct status attribute.
• The USBNetworkInterface now warns if the interface name is set, as it will be
  overwritten by the ResourceManager to assign the correct interface name.
• Fix sftp option issue in SSH driver that caused sftp to only work once per
  test run.
• ManagedFile NFS detection heuristic now does symlink resolution on the
  local host.
• XModem support within the Shelldriver was fixed by removing the newline from
  the marker.
• A typo in the NFSProviderDriver class was fixed. Documentation was already
  correct, however the classname contained an additional P.
• The --loop argument for labgrid-client console was fixed.
• The password for the ShellDriver can now be an empty string.
• The default crossbar configuration now enables auto-fragmentation to handle
  bigger labs where the payload size can be bigger than 1 megabyte.

  This prevents unexpected input, especially when using the
  ManualPowerDriver or a REPL.
• The ser2net version check for YAML configurations in the exporter was
  fixed.
• The exporter forces ser2net TCP connections for versions >=4.2.0.
• The retrieval of the DTR status for SerialPortDigitalOutputDriver was
  fixed.

  outlets.
• The ExternalConsoleDriver now correctly sets the bufsize to zero to
  prevent buffering.

Breaking changes in 24.0

• Support for Python 3.7 was dropped.

• Support for the legacy ticket authentication was dropped: If the coordinator
  logs ModuleNotFoundError on startup, switch the crossbar config to anonymous
  authentication (see .crossbar/config-anonymous.yaml for an example).

• The Debian package (debian/) no longer contains crossbar. Use the
  coordinator container <https://hub.docker.com/r/labgrid/coordinator>_ or
  install it into a separate local venv as described in the
  documentation <https://labgrid.readthedocs.io/en/latest/getting_started.html#coordinator>_.
  If you see WARNING: Ticket authentication is deprecated. Please update your coordinator. on the client when running an updated coordinator, your
  coordinator configuration may set ticket instead of anonymous auth.

• The StepReporter API has been changed. To start step reporting, you must
  now call StepReporter.start() instead of StepReporter(), and set up
  logging via labgrid.logging.basicConfig().

• Logging output when running pytest is no longer sent to stderr by default,
  since this is both chatty and also unnecessary with the improved logging
  flexibility. It it recommended to use the --log-cli-level=INFO command
  line option, or log_cli_level = INFO option in pytest.ini, but if you
  want to restore the old behavior add the following to your conftest.py
  file (note that doing so may affect the ability to use some more advanced
  logging features)::

  def pytest_configure(config):
  import logging
  import sys

     logging.basicConfig(
         level=logging.INFO,
         format='%(levelname)8s: %(message)s',
         stream=sys.stderr,
     )
  

• The interpretation of the -v command line argument to pytest has changed
  slightly. -vv is now an alias for --log-cli-level=INFO (effectively
  unchanged), -vvv is an alias for --log-cli-level=CONSOLE, and
  -vvvv is an alias for --log-cli-level=DEBUG.

• The BareboxDriver now remembers the log level, sets it to 0 on initial
  activation/reset and recovers it on boot(). During
  run()/run_check() the initially detected log level is used.

• The NFSProviderDriver now returns mount and path information on stage()
  instead of the path to be used on the target. The previous return value did
  not fit the NFS mount use case.

• The NFSProvider and RemoteNFSProvider resources no longer expect the
  internal and external arguments as they do not fit the NFS mount use
  case.

Known issues in 24.0

• Some client commands return 0 even if the command failed.

v23.0.6

Bug fixes in 23.0.6

  yaml/pyyaml#601
  yaml/pyyaml#726 (comment)

v23.0.2

Bug fixes in 23.0.2

• Print USB loader process output if log level does not cover logging it.
• Fix UnboundLocalError in atomic_replace() used by the coordinator and
  labgrid-client export to write config files.
• Let Config's get_tool() return the requested tool if it is not found in
  the config. Return the resolved path if it exists, otherwise return the value
  as is. Also drop the now obsolete tool fallbacks from the drivers and add
  tests.
• Fix USBSDMuxDevice/USBSDWireDevice udev race condition leading to
  outdated control/disk paths.
• Fix SSHDriver's explicit_sftp_mode option to allow calls to put()
