**Update Lingua Franca to v0.4.1**
The update from Lingua Franca v0.2.x to v0.4.x includes few
breaking changes.
- Some API methods have been updated.
- Mycroft-core tests have been updated to reflect improvements in
Lingua Franca's formatting and parsing.
- add LF default lang setting method to config.locale
including warning that this method will change in the future
- Add TODO's for 21.08 - moving more methods to LF
- simplify loading and setting default of languages in Skills service
- Remove unneeded wrappers for Lingua Franca functions
- Fix documentation of format and parse utils
- Fix test warnings
Add empty skill directories to a set and remove them whenever they are
no longer empty. Empty skill directories only appear once in the log.
==== Fixed Issues ====
log polution - #2750
ProcessStatus tracks the process status and allows callbacks on changes
and status queries over the messagebus.
StatusCallbackMap is used to setup the callbacks
ProcessState is an enum tracking the different states.
self._loaded_status was accessed from a message handler, if a message is
received at the precisely wrong time an exception may occur. This fixes
the init order.
Also moves the skill_updater creation to be fore the handlers are
registered.
This checks if all default skills are installed before continuing with
initial load.
For devices with no skills installed on first start this should ensure
that skills are installed before sending the mycroft.skills.initialized
to start precise training and generating the mycroft.ready message
This changes the order so the started flag is set before the settingsmeta
the send() method is called.
The send() method now exits if the started flag isn't set causing the
skill settings not to be uploaded
The upload queue will now check if it's stopped while consuming the
queue, allowing quicker shutdown if triggered while in the middle of
uploading settingsmeta.
Remove the use of the separate error message and use the wait_for_reply method
to get the converse result. The error message is left to guarantee
compatibility.
The queue will store all settingsmeta upload calls and execute them
after pairing can be verified.
Starts settings download after upload has started. When settings meta upload
has started for all skills the skill download process is triggered.
This guarantees that the settingsmeta skill_gid has been populated
properly before skills try to figure out which part of the skills data
belongs to them.
Add docstrings to upload queue
This captures any unhandled expressions and will at least make sure
they're logged properly. (Exceptions in threads are mostly not printed
to stdout).
This sleeps slightly longer than normal (10 seconds) and then tries to resume
normal operation.
