I thought fixing everything at once everywhere is obviously a bad idea: * merge conflicts until the end of time * too much burden to come up with and also to review the patch Especially the combination is problematic: a huge patch will only be looked at when someone is 'really bored', because it takes such an effort, the longer the patch lays around, the more likely a merge conflict. Hence, splitting it up is inevitable. I thought of two split up strategies: a) split up by the 'type' of style problem (like the above mentioned change) b) split up by file/directory and try to fix every 'type' at once I thought splitting by type first and potentially by directory second if it is too big still, would be best because it reduces the burden on the reviewer: only one type of change should be easier to skim over and might actually be checked by some ad-hock script if that was necessary. Or does the automatic check for white-space only changes make it secure enough so it can basically be waved through without having to look at each hunk? > somebody attempted this just a few days ago, but gave up when the scope > of the undertaking became clear. i can't find the change now ... I don't think the requirement to only accept a patch if it fixes 'every' whitespace problem in one go would be reasonable as it would result in exactly this situation: too much work to do/review it all at once so one gives up. Therefore I propose to accept fixes, even if they don't fix every issue (either in type of file space) at once: better improve something step by step, than nothing at all. >> b) only do it in files where it is used inconsistently / where the >> wrong occurrences are the minority? >> > no, do it consistently - to have a good example everywhere, and no > excuses for messing up. then we can make the automatic checking > stricter, too (which lars said was a precondition for even bothering > with a cleanup to start with). As a final goal, it should obviously be consistent everywhere but I thought it makes sense to make a difference between files where there are some random style issues here and there (most of the code) and files that are written pretty consistently but according to a different style guide (like the qmake generator stuff). The latter might probably be best fixed in an 'all types at once but on a file/directory basis' approach, so each patch would increase the 'local' consistency and be an improvement even if I or someone else would loose interest at some point in their white space cleaning spree. To summarize my suggestion: * accept partly style fixes (in either type or file space) * accept them on an a timely manner to make it feasible at all with regards to merge conflicts * intentionally ignore stuff in src/3rdparty I might even be interested in looking into the automatic style check issue, but can't promise anything. > have fun ^^ Thanks ;) Depending on your feedback, I'll give it a try. ;) - Axel _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
