2 # Geniwrapper Configuration Info
4 # This module holds configuration parameters for geniwrapper. There are two
5 # main pieces of information that are used: the database connection and
6 # the PLCAPI connection
10 # Geniwrapper uses a MYSQL database to store records. This database may be
11 # co-located with the PLC database, or it may be a separate database. The
12 # following parameters define the connection to the database.
14 # Note that Geniwrapper does not access any of the PLC databases directly via
15 # a mysql connection; All PLC databases are accessed via PLCAPI.
23 from sfa.util.debug import log
25 # xxx the path-search part could use a cleanup;
26 # why would anyone want to store the config in /usr/share/geniwrapper at all ?
27 # also, if users want to use this, it might help to store stuff in ~/.sfirc or something
29 # this would denote "/usr/share/geniwrapper/geni"
30 # geni = join(os.path.dirname(os.path.dirname(os.path.dirname(os.path.abspath(__file__)))), "geni")
34 Parse the bash/Python/PHP version of the configuration file. Very
35 fast but no type conversions.

85 # Geniwrapper uses a PLCAPI connection to perform operations on the registry,
86 # such as creating and deleting slices. This connection requires an account
87 # on the PLC server with full administrator access.
89 # The Url parameter controls whether the connection uses PLCAPI directly (i.e.
90 # Geniwrapper is located on the same machine as PLC), or uses a XMLRPC connection
91 # to the PLC machine. If you wish to use the API directly, then remove the Url
92 # field from the dictionary.
