NAME

Net::IMAP::Server::Connection - Connection to a client

DESCRIPTION

Maintains all of the state for a client connection to the IMAP server.

METHODS

new

Creates a new connection; the server will take care of this step.

server

Returns the Net::IMAP::Server that this connection is on.

coro

Returns the Coro process associated with this connection. For things interacting with this connection, it will probably be the current coroutine, except for interactions coming from event loops.

io_handle

Returns the IO handle that can be used to read from or write to the client.

model

Gets or sets the Net::IMAP::Server::DefaultModel or descendant associated with this connection. Note that connections which have not authenticated yet do not have a model.

auth

Gets or sets the Net::IMAP::Server::DefaultAuth or descendant associated with this connection. Note that connections which have not authenticated yet do not have an auth object.

client_id

When called with no arguments, returns a hashref of identifying information provided by the client. When key-value pairs are provided, sets the client properties. See RFC 2971.

selected [MAILBOX], [READ_ONLY]

Gets or sets the currently selected mailbox for this connection. Changing mailboxes triggers the sending of untagged notifications to the client, as well as calling "close" in Net::IMAP::Server::Mailbox and "select" in Net::IMAP::Server::Mailbox.

selected_read_only

Returns true of the currently selected mailbox has been forced into read-only mode. Note that the mailbox may be read-only for other reasons, so checking "read_only" in Net::IMAP::Server::Mailbox is suggested instead.

greeting

Sends out a one-line untagged greeting to the client.

handle_lines

The main line handling loop. Since we are using Coro, this cedes to other coroutines whenever we block, given them a chance to run. We additionally cede after handling every command.

update_timer

Updates the inactivity timer.

timer [AnyEvent watcher]

Returns the AnyEvent watcher in charge of the inactivity timer.

commands

Returns the number of client commands the connection has processed.

handle_command

Handles a single line from the client. This is not quite the same as handling a command, because of client literals and continuation commands. This also handles dispatch of client commands to Net::IMAP::Server::Command subclasses (see "class_for").

Any errors generated while running commands will cause a NO Server error to be sent to the client -- unless the error message starts with NO or c<BAD>, in which case it will be relayed to the client.

Returns the Net::IMAP::Server::Command instance that was run, or undef if it was a continuation line or pending interactive command.

class_for COMMAND

Returns the package name that implements the given COMMAND. See "add_command" in Net::IMAP::Server.

pending

If a connection has pending state, contains the callback that will receive the next line of input.

close

Shuts down this connection, also closing the model and mailboxes.

parse_command LINE

Parses the line into the tag, command, and options. Returns undef if parsing fails for some reason.

is_unauth

Returns true if the connection is unauthenticated.

is_auth

Returns true if the connection is authenticated.

is_selected

Returns true if the connection has selected a mailbox.

is_encrypted

Returns true if the connection is protected by SSL or TLS.

poll

Polls the currently selected mailbox, and resets the poll timer.

force_poll

Forces a poll of the selected mailbox the next chance we get.

last_poll

Gets or sets the last time the selected mailbox was polled, in seconds since the epoch.

previous_exists

The high-water mark of how many messages the client has been told are in the mailbox.

send_untagged

Sends any untagged updates about the current mailbox to the client.

get_messages STR

Parses and returns messages fitting the given sequence range. This is on the connection and not the mailbox because messages have connection-dependent sequence numbers.

sequence MESSAGE

Returns the sequence number for the given message.

capability

Returns the current capability list for this connection, as a string. Connections not under TLS or SSL always have the LOGINDISABLED capability, and no authentication capabilities. The "auth_class" in Net::IMAP::Server's "sasl_provides" in Net::IMAP::Server::DefaultAuth method is used to list known AUTH= types.

log SEVERITY, MESSAGE

Defers to "log" in Net::IMAP::Server.

untagged_response STRING

Sends an untagged response to the client; a newline ia automatically appended.

out STRING

Sends the message to the client. If the client's connection has dropped, or the send fails for whatever reason, "close" the connection and then die, which is caught by "handle_lines".
