- add check for changing filters while enumerating dirents
- add path_component_valid
- change iterator to only return valid entries (removing that burden
from user code)
This was SVN commit r2067.
- replace std::map with custom filename lookup container (more
efficient)
- split into 3 parts (was too big)
also added struct stat-like fields to vfsDirEnt
still under heavy development.
This was SVN commit r2058.
