* feat: share sudo between pty sessions
This is a first pass at a feature to cache the sudo password and share
it between different pty sessions. This makes it possible to not require
manual password entry every time sudo is used.
* feat: allow error handling and canceling sudo cmds
This adds the missing functionality that prevented failed sudo commands
from automatically closing.
* feat: restrict sudo caching to dev mode for now
* modify fullCmdStr not pk.Command
* refactor: condense ecdh encryptor creation
This refactors the common pieces needed to create an encryptor from an
ecdh key pair into a common function.
* refactor: rename promptenc to waveenc
* feat: add command to clear sudo password
We currently do not provide use of the sudo -k and sudo -K commands to
clear the sudo password. This adds a /sudo:clear command to handle it in
the meantime.
* feat: add kwarg to force sudo
In cases where parsing for sudo doesn't work, this provides an alternate
wave kwarg to use instead. It can be used with [sudo=1] at the beginning
of a command.
* refactor: simplify sudoArg parsing
* feat: allow user to clear all sudo passwords
This introduces the "all" kwarg for the sudo:clear command in order to
clear all sudo passwords.
* fix: handle deadline with real time
Golang's time module uses monatomic time by default, but that is not
desired for the password timeout since we want the timer to continue
even if the computer is asleep. We now avoid this by directly comparing
the unix timestamps.
* fix: remove sudo restriction to dev mode
This allows it to be used in regular builds as well.
* fix: switch to password timeout without wait group
This removes an unnecessary waiting period for sudo password entry.
* fix: update deadline in sudo:clear
This allows sudo:clear to cancel the goroutine for watching the password
timer.
* fix: pluralize sudo:clear message when all=1
This changes the output message for /sudo:clear to indicate multiple
passwords cleared if the all=1 kwarg is used.
* fix: use GetRemoteMap for getting remotes in clear
The sudo:clear command was directly looping over the GlobalStore.Map
which is not thread safe. Switched to GetRemoteMap which uses a lock
internally.
* fix: allow sudo metacmd to set sudo false
This fixes the logic for resolving if a command is a sudo command. This
change makes it possible for the sudo metacmd kwarg to force sudo to be
false.
