Subject: Re: [Zephyr-devel] MISRA
As a reminder, the TSC agreed upon the
Zephyr Project Coding Guidelines. We are working towards compliance to the Project CG. Yes, they
are a subset of Misra, but we are not going for Misra compliance.
The Safety Committee, in driving toward the Project goal of certification-ready, has partnered with Bugseng, as part of the community, to help build momentum towards this goal.
There is a process for removing, revising, having exceptions, etc to the CG rules. If you think a rule should be changed, open an issue in Github.
The Safety Committee is bringing an update to the TSC tomorrow, where we can have a discussion around the CG compliance work.
It’d be great to have a pre-read to frame the discussion and help us can come prepared with questions based on said update (the linked Nov 10 email in last week’s minutes is fairly
Unfortunately, TSC agendas don’t seem to be communicated in a timely fashion any more, usually sent out mere hours before the meeting (which is early morning for us on the US west
It makes it impossible to tell if it’s worth attending calls or not beforehand, and I normally skip those kind of meetings to reduce meeting overhead.
I hope we can change this to be a smoother process in the future and optimize the value of a one hour weekly meeting.
Well if code quality is truly the only goal of the steering committee and there's no politics involved then I retract everything I said. Misra offers less than nothing for this project. But I don't believe that's
true. This is 100% politics if you ask me.
Also before declaring the virtues of Misra, you'll be sure to clarify any vested financial interest you might have in the matter, right? You know, just to make sure you're not shilling.

I'd like make clear once and for all that the happiness of scanning tool
is *never* a valuable purpose under a MISRA perspective.
What matter is *only* the quality of code and MISRA is a tool to achieve

In my experience this is a consequence of a misunderstanding of what
MISRA really is.
MISRA process has rules, but also deviations and permits and the only
sane way to use it is as a tool to improve
Please forget every other idea of it as an enemy to beat or to surrender to.
As Nicolas has already done you are welcome to point out *any* proposed
change related to MISRA compliance that you think will make code worse
together with an alternative proposal to improve code at the same time.
I hope this will clarify that everyone in the community has the same
code improvement goal and, as usual, constructive collaboration is the key.
