Class WorkerConfigFile

source code

A class to read and write the qbwrk.conf file on the supervisor; this file contains blocks
herein referred to as "stanzas" for each template or host definition.

An example qbwrk.conf that has 3 stanzas looks like:
    [default]
    worker_cpus = 0
    
    [test]:
    worker_description = 'this is a test host'

    [some-host-name] : test
    worker_resources = host.foo=4
    worker_path_map = {
        "/Users/sam" = "S:"
        "/Users/test" = "T:"
    }

@ivar cfg: a dict of dicts to hold all the stanzas
    
    The top-level key is the stanza name, the string that appears between the square brackets.

    For each stanza dict, there will be a key for each parameter in the stanza, as well as the
    following reserved-word keys:
        - inherits: the list of templates that occurs after the ":" in the stanza definition
          line

        - index: the zero-based index which indicates the ordering of the stanzas in the cfgFile

    Any of the *_map type multi-line hash-like values are stored as lists of tuples, since the
    values are always C{src = target}
