From: Gusted Date: Fri, 22 Apr 2022 01:11:42 +0000 (+0000) Subject: Set correct PR status on 3way on conflict checking (#19457) (#19458) X-Git-Tag: v1.16.7~18 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=09adc26eb63fed671ce45499365139fac092c224;p=gitea.git Set correct PR status on 3way on conflict checking (#19457) (#19458) - Backport #19457 - When 3-way merge is enabled for conflict checking, it has a new interesting behavior that it doesn't return any error when it found a conflict, so we change the condition to not check for the error, but instead check if conflictedfiles is populated, this fixes a issue whereby PR status wasn't correctly on conflicted PR's. - Refactor the mergeable property(which was incorrectly set and lead me this bug) to be more maintainable. - Add a dedicated test for conflicting checking, so it should prevent future issues with this. -
