I am not too worried, * as rebase is a main porcelain, that is even hard to use in a script. so any failures are not deep down in some automation, but when found exposed quickly (and hopefully reported). * 5541bd5b8f was merged to next a month ago; internally we distribute the next branch to Googlers (on a weekly basis) and we have not had any bug reports regarding rebase. (Maybe our environment is too strict for the wide range of bugs reported) * Johannes reported that the rebase is used in GfW https://public-inbox.org/git/nycvar.QRO.7.76.6.1808241320540.73@xxxxxxxxxxxxxxxxx/ https://github.com/git-for-windows/git/pull/1800 and from my cursory reading it is part of 2.19.windows, which has a large user base. > (and would re-enable rebase.useBuiltin=true in > master right after 2.20 is out the door). That would be fine with me as well, but I'd rather document rebase.useBuiltin instead of flip-flopping the switch around the release. Have there been any fixes that are only in the C version (has the shell version already bitrotted)? Stefan
