This is the first "payoff" series in the sparse-index work. It makes 'git status' and 'git add' very fast when a sparse-index is enabled on a repository with cone-mode sparse-checkout (and a small populated set). This is based on ds/sparse-index-protections AND mt/add-rm-sparse-checkout. The latter branch is needed because it changes the behavior of 'git add' around sparse entries, which changes the expectations of a test added in patch 1. The approach here is to audit the places where ensure_full_index() pops up while doing normal commands with pathspecs within the sparse-checkout definition. Each of these are checked and tested. In the end, the sparse-index is integrated with these features: * git status * git add -A * git add . (and other pathspecs) * FS Monitor index extension. The performance tests in p2000-sparse-operations.sh improve by 95% or more, even when compared with the full-index cases, not just the sparse-index cases that previously had extra overhead. Hopefully this is the first example of how ds/sparse-index-protections has done the basic work to do these conversions safely, making them look easier than they seemed when starting this adventure.
