With this PR we might call the stop method even when the start
method of a subsystem did not successfully finish therefore we
need to make sure we guard the stop methods for potential panics
if some variables are not initialized in the contructors of the
subsystems.
Replies may contain quoted values that include spaces, newlines and/or
escaped characters (including doublequote itself). Not accounting for
that leads to errors when e. g. `COOKIEFILE` path contains spaces.
A new method, Reconnect, is added to tor controller which can be used to
reset the current connection. This will be later used in healthcheck to
help us reset the connection to Tor Daemon.
This commit adds a new response reader which replaces the old
textproto.Reader.ReadResponse. The older reader cannot handle the case
when the reply from Tor server contains a data reply line, which uses
the symbol "+" to signal such a case.
This commit adds a new method to call DEL_ONION when lnd is shutting
down. Tor controller will now be aware of the active serviceID and
removes the service upon shutdown.
This provides users an alternative over the SAFECOOKIE authentication
method, which may not be as useful if users are connecting to a remote
Tor sevrer due to lnd not being able to retrieve the cookie file.
In this commit, we extend our Tor controller to also support creating v3
onion services, as they are now supported by the Tor daemon. We also
refactor our existing AddOnion method to take in a config struct that
houses all of the required options to create/restore an onion service.
In this commit, we add our inital implementation of a Tor Controller.
This commit includes the ability for the controller to automatically
signal the Tor daemon to create a v2 onion service. This will be
expanded later on to support creating v3 onion services.
Before allowing the controller to interact with the Tor daemon, the
connection must be authenticated first. This commit includes support for
the SAFECOOKIE authentication method as a sane default.
