DESCRIPTION¶
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.
