pop3d::udb(n) 1.0.1 tcllib "Tcl POP3 Server Package"
pop3d::udb - Simple user database for pop3d
The package pop3d::udb provides simple in memory databases which can be used in conjunction with the pop3 server core provided by the package pop3d. The databases will use the names of users as keys and associates passwords and storage references with them.
Objects created by this package can be directly used in the authentication callback of pop3 servers following the same interface as servers created by the package pop3d.
- ::pop3d::udb::new ?dbName?
This command creates a new database object with an associated global Tcl command whose name is dbName.
The command dbName may be used to invoke various operations on the database. It has the following general form:
- dbName option ?arg arg ...?
Option and the args determine the exact behavior of the command.
The following commands are possible for database objects:
- dbName destroy
Destroys the database object.
- dbName add user pwd storage
Add a new user or changes the data of an existing user. Stores password and storage reference for the given user.
- dbName remove user
Removes the specified user from the database.
- dbName rename user newName
Changes the name of the specified user to newName.
- dbName lookup user
Searches the database for the specified user and returns a two-element list containing the associated password and storage reference, in this order. Throws an error if the user could not be found. This is the interface as expected by the authentication callback of package pop3d.
- dbName exists user
Returns true if the specified user is known to the database, else false.
- dbName who
Returns a list of users known to the database.
- dbName save ?file?
Saves the contents of the database into the given file. If the file is not specified the system will use the path last used in a call to dbName read. The generated file can be read by the read method.
- dbName read file
Reads the specified file and adds the contained user definitions to the database. As the file is actually source'd a safe interpreter is employed to safeguard against malicious code. This interpreter knows the add command for adding users and their associated data to this database. This command has the same argument signature as the method add. The path of the file is remembered internally so that it can be used in the next call of dbName save without an argument.
This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category pop3d of the Tcllib Trackers. Please also report any ideas for enhancements you may have for either package and/or documentation.
