get_template_vars get split into get_template_vars (for injection additional template variables only) and get_template_configs (for configuring injection of additional template). It's now possible to inject more than one of a given template type from within plugins, and template injection is more intelligent in that if a plugin's templates don't need special configuration and stick to default naming and behaviour, just declaring them inside the templates directory of the plugin will be enough to fire up everything including links to switch to tabs, sidebars etc (the plugin's name being used in such cases for link text).
In order to solve the initial handshake problem with apps, OctoPrint now supports so called app session keys which are basically API keys with a limited validity. Obtaining those keys is based on a handshake procedure backed by RSA signatures. OctoPrint needs to be aware of apps and their associated public keys (with the AppPlugin there exists a mechanism to add additional recognized apps by installing a plugin). Apps perform the handshake by first requesting a temporary key with very limited validity, then sending a message back to OctoPrint containing their id, version, the temporary key and a signature created with their private key over these three pieces of data. OctoPrint then tries to verify the signature and if successful unlocks the key to be used as a fully recognized API key.
- be able to handle slicers which can't report progress
- distinguish between registered and configured slicers (e.g. to allow uploading of profiles via the settings before having saved the path to the executable)
This way there won't be two concurrent jobs trying to slice to the same file, which would practically render the cpu cycles from any slicing jobs than the final one wasted. Also adds a new event "SlicingCancelled" that will be sent in these cases.
- File management is prepared to support folders (UI still lacking support)
- STL files are now first class citizens
- can be managed via the file list (and filtered from it)
- can be sliced on demand
- Slicing now happens via plugins
- Added Cura plugin
- uses CuraEngine directly instead of full Cura installation
- Cura profile importer for importing profiles from regular Cura installs via settings dialog
- TODO: UI for editing profiles
- API for slicing and slicing profile management
Plugins may be able to use this method for final setups before the implementations and hooks are evaluated, e.g. for adjusting their offered functionality based on what other plugins are available.
