Pierre,
Thanks for your pmccabe research summary -- most interesting !!
A while ago (after much research) I decided to use DFly + Hammer as a
reliable and efficient foundation, for my first website app (PHP +
PostgreSQL).
I am working with DFly on a QEMU / KVM VM at Elastic Hosts
www.elastichosts.com
Not enough experience yet with the EH DFly setup, to be able to give any
detailed feedback, but so far it's been great (website not yet online,
presently migrating to postgres from mysql).

My little ol' website app probably has McCabe complexity << 1 ?? For sure
nothing remotely as complicated as winged edges or a filesystem :)
But it's good to know that I'm flying (humbly, gratefully) on the remotest
fringes of a DFly community of McCabe Super-Complexity practitioners ...
Regards,
Steve

Subject: McCabe complexity
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.
