netsvc.mergeConfig("PWD",os.getcwd())
print netsvc.lookupConfig("PWD")
A single configuration item can be removed from the database using the "removeConfig()" func- tion. The configuration database can be completely emptied using the function "removeAllCon- fig()". The contents of the configuration database can be saved to a file using the "saveConfig()" function.
netsvc.removeConfig("PWD")
netsvc.saveConfig("database.cfg")
Configuration File
The only real restrictions in regard to naming is that the colon character should not be used anywhere in a name, a name should not being with an exclamation mark and whitespace should not be used at the start or end of a name. The colon character cannot be used as it used in a configuration file to sep- arate the name from the value. A leading exclamation mark should not be used as it is used to denote a comment.
If these characters are used in a name and the configuration database is saved to a file, the results when that configuration file is read back in will not be the same. The only other special character when used in a configuration file is a back slash, which when used at the end of the line, indicates the following line is part of the same value. Note that the leading whitespace and the whitespace either side of the colon will be ignored when the configuration file is read in.
! comment
value
When reading in a configuration file using "loadConfig()", an exception is raised only if the file doesn’t exist or the file couldn’t be opened. If there are no errors in the file, the value None is returned. If there are errors in the file, a string is returned which contains details of the errors and what action has been taken. By default, the details of the errors are also output via the logging system on the default log channel.
If details of any errors should be output on a specific log channel, an optional second argument can be supplied to the "loadConfig()" function giving the name of the log channel. If the value None is supplied in place of the name of the log channel, the details of the errors will not be output via the log- ger at all. The value None could be used if you wish to amend the details of the errors before they are logged.
