lisa.conf.SimpleMultiSrcConf#

class lisa.conf.SimpleMultiSrcConf(conf=None, src='user', add_default_src=True)[source]#

Bases: MultiSrcConf

Like MultiSrcConf, with a simpler config file.

conf and source are not available, and the behaviour is as all keys were located under a conf key. We do not allow overriding source for this kind of configuration to keep the YAML interface simple and dict-like

Warning

Arbitrary code can be executed while loading an instance from a YAML or Pickle file. To include untrusted data in YAML, use the !untrusted tag along with a string

Attributes

ATTRIBUTES_SERIALIZATION inherited

Attributes to be treated specially during serialization.

DEFAULT_SERIALIZATION_FMT inherited

Default format used when serializing objects.

DEFAULT_SRC inherited

Source added automatically using add_src() under the name ‘default’ when instances are built.

YAML_ENCODING inherited

Encoding used for YAML files.

__reversed__ inherited

See collections.abc.Mapping.__reversed__

Properties

STRUCTURE inherited

Class attribute defining the structure of the configuration file, as a instance of TopLevelKeyDescBase.

as_yaml_map inherited

Give a mapping suitable for storing in a YAML configuration file.

logger inherited

Convenience short-hand for self.get_logger().

Methods

from_map()

Create a new configuration instance, using the output of to_map().

to_map()

Export the configuration as a mapping.

to_yaml_map()

Write a configuration file, with the key descriptions in comments.

__class_getitem__() inherited

See collections.abc.Iterable.__class_getitem__()

__contains__() inherited

See collections.abc.Mapping.__contains__()

__copy__() inherited

Shallow copy of the nested configuration tree, without duplicating the leaf values.

__deepcopy__() inherited

__getitem__() inherited

__getstate__() inherited

Filter instances of DeferredValue that are not computed already since their runtime parameters will probably not be available after deserialization.

Add a source of configuration.

eval_deferred() inherited

Evaluate instances of DeferredValue that can be used for values that are expensive to compute.

Get a mapping of all sources for the given key, in priority order (first item is the highest priority source).

items() inherited

Override the default definition of collections.abc.Mapping.items() to allow not evaluating deferred values if necessary.

Debugging aid: log the local variables of the calling function.

Properties#

abstract property SimpleMultiSrcConf.STRUCTURE#

Inherited property, see lisa.conf.MultiSrcConf.STRUCTURE

Class attribute defining the structure of the configuration file, as a instance of TopLevelKeyDescBase.

property SimpleMultiSrcConf.as_yaml_map#

Inherited property, see lisa.conf.MultiSrcConfABC.as_yaml_map

Give a mapping suitable for storing in a YAML configuration file.

property SimpleMultiSrcConf.logger#

Inherited property, see lisa.utils.Loggable.logger

Methods#

classmethod SimpleMultiSrcConf.from_map(*args, **kwargs)[source]#

Create a new configuration instance, using the output of to_map()

SimpleMultiSrcConf.to_map()[source]#

Export the configuration as a mapping.

The return value should preserve key-specific priority override list, which is not done if directly passing that instance to dict().

SimpleMultiSrcConf.to_yaml_map(path, add_placeholder=False, placeholder='<no default>')[source]#

Write a configuration file, with the key descriptions in comments.

Parameters:
  • path (str) – Path to the file to write to.

  • add_placeholder (bool) – If True, a placeholder value will be used for keys that don’t have values. This allows creating template configuration files that list all keys.

  • placeholder (object) – Placeholder to use for missing values when add_placeholder is used.
