Add support for multiple possible bisect results (issue1228, issue1182) The real reason for both issue is that bisect can not handle cases where there are multiple possibilities for the result. Example (from issue1228): rev 0 -> good rev 1 -> skipped rev 2 -> skipped rev 3 -> skipped rev 4 -> bad Note that this patch does not only fix the reported Assertion Error but also the problem of a non converging bisect: hg init for i in `seq 3`; do echo $i > $i; hg add $i; hg ci -m$i; done hg bisect -b 2 hg bisect -g 0 hg bisect -s From this state on, you can: a) mark as bad forever (non converging!) b) mark as good to get an inconsistent state c) skip for the Assertion Error Minor description and code edits by pmezard.
