From 81f4953120f021832a0023dc704a0d7eb0ddf475 Mon Sep 17 00:00:00 2001 From: Brad King Date: Thu, 25 Aug 2011 12:49:13 -0400 Subject: [PATCH] rev-list: Demonstrate breakage with --ancestry-path --all The option added by commit ebdc94f3 (revision: --ancestry-path, 2010-04-20) does not work properly in combination with --all, at least in the case of a criss-cross merge: b---bc / \ / a X \ / \ c---cb There are no descendants of 'cb' in the history. The command git rev-list --ancestry-path cb..bc correctly reports no commits. However, the command git rev-list --ancestry-path --all ^cb reports 'bc'. Add a test case to t6019-rev-list-ancestry-path demonstrating this breakage.
