I've been working on a land surveying program for over eight years. According
to pmccabe, the most complicated functions are pointlist::maketin (62), which
creates a triangulated irregular network, and triangle::subdivide (58/65),
which subdivides a triangle into monotonic regions. The TIN uses a tangledly
hierarchical data structure called "winged edge", in which points, edges, and
triangles all point to each other. It took me years to make it work right.
I checked HAMMER source code with pmccabe. The most complex function is
hammer_vfs_mount, at 51. In hammer2, the most complex is
hammer2_cluster_resolve, at 79/90. In the hammer utility, the main program is
93/144, and in hammer2 68/78.
Whoever said McCabe complexity should be at most 10 never worked on such
complex data structures as a winged edge or a filesystem.
