Revision a0ebe573a516a1530a2c072e513fa7f529781dd0 authored by Adam Simpkins on 05 June 2008, 08:56:19 UTC, committed by Junio C Hamano on 06 June 2008, 16:23:09 UTC
This change teaches the graph API that only the first parent of each commit is interesting when "--first-parent" was specified. This change also consolidates the graph parent walking logic into two new internal functions, first_interesting_parent() and next_interesting_parent(). A simpler fix would have been to simply break at the end of the 2 existing for loops when graph->revs->first_parent_only is set. However, this change seems nicer, especially if we ever need to add any new loops over the parent list in the future.
