repair: speed up stripping of many roots
repair.strip() expects a set of root revisions to strip. It then
builds the full set of descedants by walking the descandants of
each. It is rare that more than a few roots get passed in, but if that
happens, it will wastefully walk the changelog for each root. So let's
just walk it once.
I noticed this because the narrowhg extension was passing not only
roots, but all the commits to strip. When there were tens of thousands
of commits to strip, this resulted in quadratic behavior with that
extension.

# Base Revsets to be used with revsetbenchmarks.py script # # The goal of this file is to gather a limited amount of revsets that allow a # good coverage of the internal revsets mechanisms. Revsets included should not # be selected for their individual implementation, but for what they reveal of # the internal implementation of smartsets classes (and their interactions). # # Use and update this file when you change internal implementation of these # smartsets classes. Please include a comment explaining what each of your # addition is testing. Also check if your changes to the smartset class makes # some of the tests inadequate and replace them with a new one testing the same # behavior. # # If you want to benchmark revsets predicate itself, check 'all-revsets.txt'. # # The current content of this file is currently likely not reaching this goal # entirely, feel free, to audit its content and comment on each revset to # highlight what internal mechanisms they test. all() draft() ::tip draft() and ::tip ::tip and draft() 0::tip roots(0::tip) author(lmoscovicz) author(mpm) author(lmoscovicz) or author(mpm) author(mpm) or author(lmoscovicz) tip:0 0:: # those two `roots(...)` inputs are close to what phase movement use. roots((tip~100::) - (tip~100::tip)) roots((0::) - (0::tip)) 42:68 and roots(42:tip) ::p1(p1(tip)):: public() :10000 and public() draft() :10000 and draft() roots((0:tip)::) (not public() - obsolete()) (_intlist('20000\x0020001')) and merge() parents(20000) (20000::) - (20000) # The one below is used by rebase (children(ancestor(tip~5, tip)) and ::(tip~5))::
