I am now ready to start doing this, but before I do, I'd like to decompose the subject into manageable tasks with a bit of help from RP and the community: https://www.yoctoproject.org/community/yocto-project-engineering-request-for-quotation/ ==== Core Workflow – Process Improvements Background The project builds everything from source by default. This means it has a reputation for being slow and heavy. There are ways the project can accelerate this which means faster workflows and improved developer experience but these are currently cumbersome to use. Rationale The project aims to defragment customised embedded Linux. This is important as if we succeed at this, it gives benefits to the wider ecosystem through making it easier to inject security fixes and an ability to share and collaborate without re-inventing the wheel. To do this, we need to provide best-in-class support and compete against binary distributions for usability and speed. One way we can do this is provide better support for binary artifacts via our sstate mechanism. We do already have some of this functionality in our “extensible SDK” or “eSDK”. Deliverables Enable a public sstate mirror via a content delivery network (CDN) and populate using the autobuilder Ensure CDN sstate is reused under normal use case scenarios, particularly for slow components like rust-native. Identify any common sstate mismatch causes. Ensure test cases are added to cover the use cases and prevent regressions. Add lock and unlock commands to allow specific components to be locked down to specific sstate checksums or allow them to vary Allow switching between eSDK and non-eSDK modes Add tooling so we can understand why something is rebuilding when it isn’t expected to. ======= So: where to start? Do we need to 'design' something, or maybe time should go directly into addressing specific sore points? All feedback welcome. There's also an unfinished patchset for adding bblock/bbunlock, which I would prefer to *not* 'take over and finish' but rather see the author get it merged: https://patchwork.yoctoproject.org/project/oe-core/list/?series=15276 Thanks, Alex
