The can-working-tree-updates-be-skipped check has had a long and blemished history. The update can be skipped iff: a) The merge is clean b) The merge matches what was in HEAD (content, mode, pathname) c) The target path is usable (i.e. not involved in D/F conflict) Traditionally, we split b into parts: b1) The merged result matches the content and mode found in HEAD b2) The merged target path existed in HEAD Steps a & b1 are easy to check; we have always gotten those right. While it is easy to overlook step c, this was fixed seven years ago with commit4ab9a157d0("merge_content(): Check whether D/F conflicts are still present", 2010-09-20). merge-recursive didn't have a readily available way to directly check step b2, so various approximations were used: * In commitb2c8c0a762("merge-recursive: When we detect we can skip an update, actually skip it", 2011-02-28), it was noted that although the code claimed it was skipping the update, it did not actually skip the update. The code was made to skip it, but used lstat(path, ...) as an approximation to path-was-tracked-in-index-before-merge. * In commit5b448b8530("merge-recursive: When we detect we can skip an update, actually skip it", 2011-08-11), the problem with using lstat was noted. It was changed to the approximation path2 && strcmp(path, path2) which is also wrong. !path2 || strcmp(path, path2) would have been better, but would have fallen short with directory renames. * Inc5b761fb27("merge-recursive: ensure we write updates for directory-renamed file", 2018-02-14), the problem with the previous approximation was noted and changed to was_tracked(path) That looks close to what we were trying to answer, but was_tracked() as implemented at the time should have been named is_tracked(); it returned something different than what we were looking for. * To make matters more complex, fixing was_tracked() isn't sufficient because the splitting of b into b1 and b2 is wrong. Consider the following merge with a rename/add conflict: side A: modify foo, add unrelated bar side B: rename foo->bar (but don't modify the mode or contents) In this case, the three-way merge of original foo, A's foo, and B's bar will result in a desired pathname of bar with the same mode/contents that A had for foo. Thus, A had the right mode and contents for the file, and it had the right pathname present (namely, bar), but the bar that was present was unrelated to the contents, so the working tree update was not skippable. Fix this by introducing a new function: was_tracked_and_matches(o, path, &mfi.oid, mfi.mode) and use it to directly check for condition b.
