pop3d::dbox(n) 1.0.1 pop3d "Tcl POP3 Server Package"
pop3d::dbox - Simple mailbox database for pop3d
package require Tcl 8.2
package require pop3d::dbox ?1.0.1?
The package pop3d::dbox provides simple/basic mailbox
management facilities. Each mailbox object manages a single base
directory whose subdirectories represent the managed mailboxes. Mails
in a mailbox are represented by files in a mailbox directory, where
each of these files contains a single mail, both headers and body, in
RFC 822 (http://www.rfc-editor.org/rfc/rfc822.txt) conformant
format.
Any mailbox object following the interface described below can be used
in conjunction with the pop3 server core provided by the package
pop3d. It is especially possible to directly use the objects
created by this package in the storage callback of pop3 servers
following the same interface as servers created by the package
pop3d.
- ::pop3d::dbox::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 mailbox database and all transient data. The directory
associated with the object is not destroyed.
- dbName base base
-
Defines the base directory containing the mailboxes to manage. If this
method is not called none of the following methods will work.
- dbName add mbox
-
Adds a mailbox of name mbox to the database. The name must be a
valid path component.
- dbName remove mbox
-
Removes the mailbox specified through mbox, and the mails
contained therein, from the database. This method will fail if the
specified mailbox is locked.
- dbName move old new
-
Changes the name of the mailbox old to new.
- dbName list
-
Returns a list containing the names of all mailboxes in the directory
associated with the database.
- dbName exists mbox
-
Returns true if the mailbox with name mbox exists in the
database, or false if not.
- dbName locked mbox
-
Checks if the mailbox specified through mbox is currently locked.
- dbName lock mbox
-
This method locks the specified mailbox for use by a single connection
to the server. This is necessary to prevent havoc if several
connections to the same mailbox are open. The complementary method is
unlock. The command will return true if the lock could be set
successfully or false if not.
- dbName unlock mbox
-
This is the complementary method to lock, it revokes the lock
on the specified mailbox.
- dbName stat mbox
-
Determines the number of messages in the specified mailbox and returns
this number. This method fails if the mailbox mbox is not
locked.
- dbName size mbox ?msgId?
-
Determines the size of the message specified through its id in
msgId, in bytes, and returns this number. The command will
return the size of the whole maildrop if no message id was specified.
If specified the msgId has to be in the range "1 ... [dbName stat]"
or this call will fail. If stat was not called before this
call, size will assume that there are zero messages in the
mailbox.
- dbName dele mbox msgList
-
Deletes the messages whose numeric ids are contained in the
msgList from the mailbox specified via mbox.
The msgList must not be empty or this call will fail.
The numeric ids in msgList have to be in the range "1 ...
[dbName stat]" or this
call will fail. If stat was not called
before this call, dele will assume
that there are zero messages in the mailbox.
- storageCmd get mbox msgId
-
Returns a handle for the specified message. This handle is a mime
token following the interface described in the documentation of
package mime. The token is read-only. In other
words, the caller is allowed to do anything with the token except to
modify it.
The msgId has to be in the range "1 ...
[dbName stat]" or this
call will fail. If stat was not called
before this call, get will assume
that there are zero messages in the mailbox.
