pop3d::udb(n) 1.0.1 "Tcl POP3 Server Package"
pop3d::udb - Simple user database for pop3d
package require Tcl 8.2
package require pop3d::udb ?1.0.1?
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.
