Hello Snapcrafters! The Snapcraft team is pleased to announce that version 2.43 is out.
Contributions
This release saw some excellent contributions from outside the snapcraft core team, and we want to give a shout out to those folks. A team thank you to:
New in this release
Core
lifecycle
snapcraft now accurately identifies source and build changes and re-executes steps accordingly. This new mode is enabled through configuration in this release. To enable it now, open (or create) ~/.config/snapcraft/cli.cfg and add the following entry:
[Lifecycle]
outdated_step_action = clean
Take a look at the feature in action in the following video,
build providers
- Per project SSH key management support was added. Each project will have its own key generated.
- Snap injection logic has been improved and should be faster for the currently exposed build providers (i.e., multipass).
- Use of cleanbuild on OS X now defaults to using multipass transparently.
- Underlying image retrieving logic has been added to have a unique image available to build with any provider which would target a specific base (this is still under the covers and needs enabling).
error reporting
Snapcraft internal errors now prompt to send a report to Sentry, helping us identify the most pressing issues. An option to always report errors has also been added. Set SNAPCRAFT_ENABLE_SILENT_REPORT to a truthful value to automatically send the report.
The prompt asks if you always want to send error reports. If you choose this and change your mind, you can edit the option in snapcraft's configuration.
Take a look at this video to get a quick idea of the error reporting experience:
manifest
For better tracking of deliverables, if SNAPCRAFT_BUILD_INFO is set, the resulting manifest.yaml will contain the version of snapcraft used to create the snap.
templates
The templates machinery has made it into this release. However, no new template has been added as we want to carefully review any of these with all relevant stakeholders to provide the stability and consistency which was not fully achieved with shared parts.
CLI
templates
Although no template is available today, the commands to work with them are already available (these are working names for the commands and subject to change):
- template: Show contents of template.
- expand-templates: Display snapcraft.yaml with all templates applied.
- templates: List available templates (it is currently missing its counterpart
list-templates).
Cleaner output
Tracebacks are now handled in a less verbose manner and stored to a file for inspection instead of printed to the screen.
The verbosity of output when using --debug has been reduced considerably as well, leaving the option with a more user-focused role (i.e., debug the actual project being worked on and not snapcraft itself).
The explicit traceback and the output previously seen when using debug can be enabled through use of an environment variable, SNAPCRAFT_ENABLE_DEVELOPER_DEBUG=yes.
Plugins
go
The go plugin now knows not to install the debs if the well known snap is used.
Here's a video showing off the functionality:
kernel
As was done with Ubuntu based deb kernels, the kernel plugin now also installs the .config used at the root of the snap as config-$kernelversion.
rust
Given that they are well integrated into cargo, tests are now run for cargo builds.
jhbuild
The jhbuild plugin can now properly run as root and has been greatly simplified.
