I have already demonstrated the index works. They are tagged as "RFC" but actually quite complete and I can polish them up in 2 days. And my latest analysis indicates it could be made to be just 20ms difference from obscache. I'd note that obscache is also incomplete in this series - the way it handles strip (could be triggered by histedit/rebase --abort) is bad for huge repos (the next command takes 7 seconds). When talking about performance. Please take that 7 seconds after strip (or histedit --abort) into consideration and not only just read operations. > Realistically, any non-revlog storage engine is going to have to work out > similar cache invalidation hooks anyway, isn't it? True. But the index stuff does not depend on changelog. Its single source of truth is obsstore. So it's easier. _______________________________________________ Mercurial-devel mailing list Mercurial-devel@mercurial-scm.org https://www.mercurial-scm.org/mailman/listinfo/mercurial-devel
