From 3ce8888fb499f9646b770306be6e2c7674a75199 Mon Sep 17 00:00:00 2001 From: James Limbouris Date: Wed, 8 Dec 2021 02:11:58 +0000 Subject: [PATCH] subtree: fix argument handling in check_parents 315a84f9aa0 (subtree: use commits before rejoins for splits, 2018-09-28) changed the signature of check_parents from 'check_parents [REV...]' to 'check_parents PARENTS_EXPR INDENT'. In other words the variable list of parent revisions became a list embedded in a string. However it neglected to unpack the list again before sending it to cache_miss, leading to incorrect calls whenever more than one parent was present. This is the case whenever a merge commit is processed, with the end result being a loss of performance from unecessary rechecks. The indent parameter was subsequently removed in e9525a8a029 (subtree: have $indent actually affect indentation, 2021-04-27), but the argument handling bug remained. For consistency, take multiple arguments in check_parents, and pass all of them to cache_miss separately.
