This is a (relatively) simple state machine running in the
data callbacks invoked by the msgpack unpacking stack machine
(the same machine is used in msgpack-c and msgpack-python,
changes are minor and cosmetic, e.g. removal of msgpack_unpack_object,
removal of the C++ template thus porting to C and so on).
Compared to the previous solution this has multiple advantages
- msgpack-c dependency is removed
- this approach is faster and requires fewer and smaller
memory allocations
Testability of the two solutions does not differ in my
professional opinion(tm).
Two other changes were rolled up; _hashindex.c can be compiled
without Python.h again (handy for fuzzing and testing);
a "small" bug in the cache sync was fixed which allocated too
large archive indices, leading to excessive archive.chunks.d
disk usage (that actually gave me an idea).
use borg instead attic except at the places where it was used:
- as toplevel package name, directory name, file name
- to refer to original attic
remove sphinx upload make command, will be replaced by github.io site later
remove references to binary downloads and linux packages for now
remove some software name references, fix grammar
use borgbackup rather than borg-backup (or borg) in URLs,
less name collision issues, better search results, no validity issues with "-"
