And adding one-line-per-commit from side branches does break existing functionality. You seem to be arguing that more information is always good and does not break existing functionality, but summarizing by omitting irrelevant details *is* a feature. Do you honestly believe that a change to make the full "log -p" output in submodule log be a "backward compatible" change?? > > Merge branch "topic1" into "master" > > Merge branch "topic2" into "master" > > Merge branch "origin/develop" into "master" > > Merge branch "topic3" into "master" It is not a real argument; it is something you can fix by naming your branches more sensibly, which would make you a better developer regardless of how submodule-log is shown. >>> And it's simpler to implement.

Can you explain: > > "...we can do without not just an option but a feature to omit > --first-parent..." I am not sure how to phrase that any easier. Sorry. Assuming that you consider output with and without --first-parent does not make much of a difference (i.e. "minor difference in behaviour"), instead of dropping --first-parent unconditionally, like you seem to be pushing with the argument, we can unconditionally keep the --first-parent and do not change anything. The end result would not make much of a difference either way, and not doing anything is much simpler than dropping --first-parent. Hopefully you can see how absurd that line of reasoning is. So do not make the same argument to push for changing the behaviour unconditionally. If you think the new behaviour can help _some_ users, then you would need the feature and a knob to enable it. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
