revset.bisect: add 'ignored' set to the bisect keyword The 'ignored' changesets are outside the bisection range, but are changesets that may have an impact on the outcome of the bisection. For example, in case there's a merge between the good and bad csets, but the branch-point is out of the bisection range, and the issue originates from this branch, the branch will not be visited by bisect and bisect will find that the culprit cset is the merge. So, the 'ignored' set is equivalent to: ( ( ::bisect(bad) - ::bisect(good) ) | ( ::bisect(good) - ::bisect(bad) ) ) - bisect(range) - all ancestors of bad csets that are not ancestors of good csets, or - all ancestors of good csets that are not ancestors of bad csets - but that are not in the bisection range.

hbisect.get: use simpler code with repo.set(), fix 'pruned' set Use repo.set() wherever possible, instead of locally trying to reproduce complex graph computations. 'pruned' now means 'all csets that will no longer be visited by the bisection'. The change is done is this very patch instead of its own dedicated one becasue the code changes all over the place, and the previous 'pruned' code was totally rewritten by the cleanup, so it was easier to just change the behavior at the same time. The previous series went in too fast for this cleanup pass to be included, so here it is. ;-) Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
