The "selective lazy" implementation used
isGlobMatch
to determine whether a particular asset was "lazy" or not - this turns out was inefficient because for every glob it would be compiled to a regex for every asset. This regressed performance of incremental changes significantly with a large asset graph.This change instead uses the
globToRegex
util to pre-compile the globs at option resolution time, and then does regex matches against these pre-compiled regexes. This has fixed the performance issue in our usage.🚨 Test instructions
