From 58a8756a98fbd08add1c25ac61ffa4f4f8a6e776 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Fri, 29 Apr 2011 11:36:17 +0200 Subject: [PATCH] Make --dirstat=0 output directories that contribute < 0.1% of changes The expected output from --dirstat=0, is to include any directory with changes, even if those changes contribute a minuscule portion of the total changes. However, currently, directories that contribute less than 0.1% are not included, since their 'permille' value is 0, and there is an 'if (permille)' check in gather_dirstat() that causes them to be ignored. This test is obviously intended to exclude directories that contribute no changes whatsoever, but in this case, it hits too broadly. The correct check is against 'this_dir' from which the permille is calculated. Only if this value is 0 does the directory truly contribute no changes, and should be skipped from the output. This patches fixes this issue, and updates corresponding testcases to expect the new behvaior.
