benchbuild.utils.settings module

Configuration utilities.

Settings are stored in a dictionary-like configuration object. All settings are modifiable by environment variables that encode the path in the dictionary tree.

Inner nodes in the dictionary tree can be any dictionary. A leaf node in the dictionary tree is represented by an inner node that contains a value key.

class benchbuild.utils.settings.ConfigDumper(stream, default_style=None, default_flow_style=None, canonical=None, indent=None, width=None, allow_unicode=None, line_break=None, encoding=None, explicit_start=None, explicit_end=None, version=None, tags=None)

class benchbuild.utils.settings.ConfigPath(components)

Bases: object

Wrapper around paths represented as list of strings.

Tests: >>> path = local.path(‘/tmp/test/foo’) >>> p = ConfigPath([‘tmp’]); str(p) ‘/tmp’ >>> p = ConfigPath(str(path)); str(p) ‘/tmp/test/foo’ >>> p.validate() The path ‘/tmp/test/foo’ is required by your configuration. >>> p.validate(); path.delete()

>>> p = ConfigPath([]); str(p)
'/'

static path_to_str(components)

validate()

Make sure this configuration path exists.

class benchbuild.utils.settings.Configuration(parent_key, node=None, parent=None, init=True)

Bases: object

Dictionary-like data structure to contain all configuration variables.

This serves as a configuration dictionary throughout benchbuild. You can use it to access all configuration options that are available. Whenever the structure is updated with a new subtree, all variables defined in the new subtree are updated from the environment.

Environment variables are generated from the tree paths automatically.

CFG[“build_dir”] becomes BB_BUILD_DIR CFG[“llvm”][“dir”] becomes BB_LLVM_DIR

The configuration can be stored/loaded as YAML.

Examples

>>> from benchbuild.utils import settings as s
>>> c = s.Configuration('bb')
>>> c['test'] = 42
>>> c['test']
BB_TEST=42
>>> str(c['test'])
'42'
>>> type(c['test'])
<class 'benchbuild.utils.settings.Configuration'>

filter_exports()

has_default()

Check, if the node contains a ‘default’ value.

has_value()

Check, if the node contains a ‘value’.

init_from_env()

Initialize this node from environment.

If we’re a leaf node, i.e., a node containing a dictionary that consist of a ‘default’ key, compute our env variable and initialize our value from the environment. Otherwise, init our children.

is_leaf()

Check, if the node is a ‘leaf’ node.

load(_from)

Load the configuration dictionary from file.

store(config_file)

Store the configuration dictionary to a file.

to_env_dict()

Convert configuration object to a flat dictionary.

value

Return the node value, if we’re a leaf node.

Examples

>>> c = Configuration("test")
>>> c['x'] = { "y" : { "value" : None }, "z" : { "value" : 2 }}
>>> c['x']['y'].value == None
True
>>> c['x']['z'].value
2
>>> c['x'].value
TEST_X_Y=null
TEST_X_Z=2

exception benchbuild.utils.settings.InvalidConfigKey

Bases: RuntimeWarning

Warn, if you access a non-existing key benchbuild’s configuration.

benchbuild.utils.settings.available_cpu_count()

Get the number of available CPUs.

Number of available virtual or physical CPUs on this system, i.e. user/real as output by time(1) when called with an optimally scaling userspace-only program.

Returns:Number of avaialable CPUs.

benchbuild.utils.settings.convert_components(value)

benchbuild.utils.settings.escape_yaml(raw_str)

Shell-Escape a yaml input string.

Parameters:raw_str – The unescaped string.

benchbuild.utils.settings.find_config(test_file=None, defaults=None, root='.')

Find the path to the default config file.

We look at :root: for the :default: config file. If we can’t find it there we start looking at the parent directory recursively until we find a file named :default: and return the absolute path to it. If we can’t find anything, we return None.

Parameters:

• default – The name of the config file we look for.
• root – The directory to start looking for.

Returns:

Path to the default config file, None if we can’t find anything.

benchbuild.utils.settings.is_yaml(cfg_file)

benchbuild.utils.settings.path_constructor(loader, node)

” Construct a ConfigPath object form a scalar YAML node.

Tests:

>>> yaml.add_constructor("!create-if-needed", path_constructor)
>>> yaml.load("{'test': !create-if-needed '/tmp/test/foo'}")
{'test': ConfigPath(components=['tmp', 'test', 'foo'])}

benchbuild.utils.settings.path_representer(dumper, data)

Represent a ConfigPath object as a scalar YAML node.

Tests:

>>> yaml.add_representer(ConfigPath, path_representer)
>>> yaml.dump({'test': ConfigPath('/tmp/test/foo')})
"{test: !create-if-needed '/tmp/test/foo'}\n"

benchbuild.utils.settings.setup_config(cfg, config_filenames=None, env_var_name=None)

This will initialize the given configuration object.

The following resources are available in the same order:

1. Default settings.
2. Config file.
3. Environment variables.

WARNING: Environment variables do _not_ take precedence over the config

file right now. (init_from_env will refuse to update the value, if there is already one.)

Parameters:

• config_filenames – list of possible config filenames
• env_var_name – name of the environment variable holding the config path

benchbuild.utils.settings.to_env_var(env_var, value)

benchbuild.utils.settings.to_yaml(value)

benchbuild.utils.settings.update_env(cfg)

benchbuild.utils.settings.upgrade(cfg)

Provide forward migration for configuration files.

benchbuild.utils.settings.uuid_add_implicit_resolver(Loader=<class 'benchbuild.utils.settings.ConfigLoader'>, Dumper=<class 'benchbuild.utils.settings.ConfigDumper'>)
