Removed old loginstate.subscribe method and migrated existing code to new mechanism.
This should allow plugins to only request their sensitive data if a user is a) logged in and has b) the necessary rights for a request. The server should still do additional auth checks, but this way no unnecessary request have to be made.
* Renamed userjson to userdata, removed original userdata (developers will live if they need to ensure their supplied userdata is valid JSON)
* Input validation for userdata parameter - a HTTP 400 response will be generated if userdata can't be parsed as JSON
* Adjusted documentation accordingly
* moved virtual printer into plugin
* made default serial factory use supplied parameters instead of directly utilizing self._port and similar
* documented new hook
f98ebaaf moved the passive_logon code to a new function from
api/__init__.py to util/flask.py. Before that move any fallthrough
would hit return NO_CONTENT, but now it returns nothing which makes
flask complain.
This hook allows the plugin to create the serial port object (or pass to
the next hook or the builtin serial port handler) which allows for
serial communication filtering or a different communication transport.
Use @foosel's code to use the same loop for hooks as well as the
builtin.
Also, modify the cura slicer to recognize the setting and avoid
adjusting the model position, just leave it in the center where it would
be on a circular platform
Having to wait for the first serial timeout before sending the first M105 even when not waiting for seeing a "start" caused unnecessary wait times for reaching the "Operational" state.
Add computed property "name" to function objects if not provided by the
browser, to avoid dropping out of main.js before it is finished.
(cherry picked from commit 68215c6)
Tracking the "ok" attached to a resend is necessary in order to make sure that it does not trigger the resend of the next line after the requested one right after, causing resend loops in some cases, e.g. "> 100", "> 101" , "< rs 100", "ok", "> 100", "< expected 100, got 101, rs 100" -- here the last error from the firmware could not be processed as "false negative" correctly (101 was already sent to the printer when it detected the error for 100, so this error just needs to be ignored) since the resend flag was already cleared due to line 100 and 101 having been enqueued, 100 in the resend handler, 101 due to the following ok. This patch fixes the latter, thus solving the problem.
Plugins may be enabled and disabled during runtime. If they are of types which allow hot loading, this will be done. Otherwise they will be marked as pending and updated after a restart. Same for installation and uninstallation.
