# ApplyEdit - Applies an edit command to a line in a configuration |
# Register a command processor. This function is invoked to register a sub |
# file. It is the caller's responsiblity to validate the |
# to process a request. Once registered, the ProcessRequest sub can automatically |
# edit line. |
# dispatch requests to an appropriate sub, and do the top level validity checking |
|
# as well: |
|
# - Is the keyword recognized. |
|
# - Is the proper client type attempting the request. |
|
# - Is the request encrypted if it has to be. |
# Parameters: |
# Parameters: |
# $directive - A single edit directive to apply. |
# $request_name - Name of the request being registered. |
# Edit directives are of the form: |
# This is the command request that will match |
# append|newline - Appends a new line to the file. |
# against the hash keywords to lookup the information |
# replace|key|newline - Replaces the line with key value 'key' |
# associated with the dispatch information. |
# delete|key - Deletes the line with key value 'key'. |
# $procedure - Reference to a sub to call to process the request. |
# $editor - A config file editor object that contains the |
# All subs get called as follows: |
# file being edited. |
# Procedure($cmd, $tail, $replyfd, $key) |
|
# $cmd - the actual keyword that invoked us. |
|
# $tail - the tail of the request that invoked us. |
|
# $replyfd- File descriptor connected to the client |
|
# $must_encode - True if the request must be encoded to be good. |
|
# $client_ok - True if it's ok for a client to request this. |
|
# $manager_ok - True if it's ok for a manager to request this. |
|
# Side effects: |
|
# - On success, the Dispatcher hash has an entry added for the key $RequestName |
|
# - On failure, the program will die as it's a bad internal bug to try to |
|
# register a duplicate command handler. |
