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.
  • labgrid was switched from pysnmp to pysnmp-lexstudio.
  • Support for Segger J-Link was added.
  • Place tags are now exposed by the RemotePlace.
  • The sync-places contrib script has gained support for named matches.
  • Remote support for YKush Devices was added.
  • Support for sigrok DMMs was added.
  • Support for Digital Outputs switched via HTTP was added.
  • The QEMUDriver has a new get_qemu_base_args() function which can be used to
    extract the arguments passed to qemu.
  • The SSHDriver has gained support to forward unix sockets.
  • The exporter has gained an --fqdn argument to set the hostname to the
    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.
  • The RawNetworkInterfaceDriver allows the replay and recording of network
    packets on ethernet interfaces.
  • The i.MX93 usb loader USB ID has been added to the IMXUSBLoader resource.
  • Support for udev matched GPIOs has been added.
  • labgrid-client now has a write-files subcommand to copy files onto mass
    storage devices.
  • The NetworkPowerPort supports a new backend ubus. It controls PoE
    switches running OpenWrt using the ubus interface.
  • The pyproject.toml gained a config for ruff <https://github.com/astral-sh/ruff>_.
  • setuptools_scm is now used to generate a version file.
  • labgrid-client console will fallback to telnet if microcom is not available.
  • A power backend for tinycontrol.eu IP Power Socket 6G10A v2 was added.
  • Labgrid now publishes arm64 docker images.
  • Labgrid's YAML parser will now warn when mapping keys are duplicated and thus
    overwritten.
  • LC USB Relais are now supported.

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.
  • labgrid now uses its own pyserial fork from pypi since installation from
    github as an egg is no longer properly supported.
  • The build-and-release workflow supports building wheels.
  • 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.
  • An UnboundLocalError inside the atomic_replace code which is used inside the
    coordinator was fixed.
  • Resources of different classes can now have the same name.
  • A bug within the pytest logging setup was fixed.
  • The QemuDriver correctly handles the different command lines for virgl
    enablement.
  • A bug was fixed where resource names were ignored during lookup of the correct
    power driver.
  • ManagedFile was fixed to work with the stat command on Darwin.
  • 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.
  • The SSHDriver redirects /dev/null to stdin of commands run via SSH.
    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.
  • The SSHDriver keepalive is now correctly stopped when using existing
    connections.
  • The power backend for raritan devices now supports devices with more than 16
    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.
