Hi Bohdan,

Thanks for the good initiative – MISRA fixes are more than welcome. I am not sure how big the patch you have in mind, but it should be ok if it’s reviewable. You might also want to split by violation types if the patch is huge.

Hope that helps. Looking forward to the patch, Anton

Hi,

In our local copy of TFM we are running Coverity tools which performs MISRA, CERT-C and CODING static analysis checks on TFM codebase (I will refer to this as MISRA fixes for simplicity). During our development we did a bunch of fixes for the violations (not all rules but still significant number of changes). Most of these changes are small (e.g. U/UL postfixes, fixed width types usage, header file fixes etc…). When we do version updates or generally port code between upstream and local copy of TFM we have to deal with merge conflicts in these lines effected by MISRA fixes. To avoid these issues we would like to push these fixes upstream. There are quite a few changes and having everything in one patch will really simplify our work as we would not have to divide the changes. We would like to know whether creating one bigger patch with all the changes would be acceptable for the review?

Best regards, Bohdan Hunko

Hi Bohdan,

May I suggest to push the patches in small changes to ease review and then perhaps squash some of them? Maybe we can attempt to organize them across categories or rules? Essentially I understand the intent and suggesting a way in between if possible.

Thanks Nick
