From 9f68d2a003c7f4036f5118ea47938b5335557e21 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 10 Mar 2016 13:19:54 +0100 Subject: [PATCH 1/5] pull: drop confusing prefix parameter of die_on_unclean_work_tree() In cmd_pull(), when verifying that there are no changes preventing a rebasing pull, we diligently pass the prefix parameter to the die_on_unclean_work_tree() function which in turn diligently passes it to the has_unstaged_changes() and has_uncommitted_changes() functions. The casual reader might now be curious (as this developer was) whether that means that calling `git pull --rebase` in a subdirectory will ignore unstaged changes in other parts of the working directory. And be puzzled that `git pull --rebase` (correctly) complains about those changes outside of the current directory. The puzzle is easily resolved: while we take pains to pass around the prefix and even pass it to init_revisions(), the fact that no paths are passed to init_revisions() ensures that the prefix is simply ignored. That, combined with the fact that we will *always* want a *full* working directory check before running a rebasing pull, is reason enough to simply do away with the actual prefix parameter and to pass NULL instead, as if we were running this from the top-level working directory anyway.
