This release introduces a major version update with several new features
and package additions.
The original C swupd-server https://github.com/clearlinux/swupd-server and
bundle-chroot-builder https://github.com/clearlinux/bundle-chroot-builder
are now integrated into mixer itself under the swupd/ and builder/ packages,
and used as libraries instead of standalone binaries. The rewrite closely ties
the swupd-server and chroot-builder functionality directly into mixer, while
providing the benefits of the Go language. The new functionality lives side
by side with the original implementation for the time being, until further
testing is completed to guarantee consistent, stable behaviour. However,
the new features may (and should) be used by providing --new-swupd and
--new-chroots with the appropriate mixer subcommands. They will become the
default as the old standalone build programs are deprecated.
The second major update is a new CLI written using the Cobra framework.
Existing commands are only subtly different:
old new
---- ----
mixer build-chroots mixer build chroots
mixer build-update mixer build update
mixer init-mix mixer init
-flags --flags
In short, the command hierarchy is changed such that things like 'build'
are top level commands, and the things they build are exposed under them,
rather than making many hyphenated commands. Flags are implemented as
regular short and long options, where long options use two hyphens
instead of one.
New commands have been added to make bundle lifecycle management easier,
and to ensure bundles are manipulated correctly without manually copying
things in specific folders. See all new commands by typing "mixer" *enter*.
Miscellaneous fixes to things such as init creating the builder.conf and
doing more upfront work for the user have also been implemented. The
goal of these updates is to streamline the operation of mixer and
improve usability.
Many tests were added for the code base; unit tests for the new
swupd and chroot libraries, BAT tests to cover the interface and
functionality of the Mixer itself, and extensive linting were added to
catch regressions and enforce cleaner code.
