Installation:
`./scripts/opam-pin.sh && opam install tezos-node tezos-client`
Upgrade installed packages after a `git pull` (opam2 only):
`./scripts/opam-upgrade.sh`
Remove and cleanup every from the opam repo:
`./scripts/opam-unpin.sh`
This is a dirty and non-optimized backend, it is still faster than the
current git backend.
Main drawbacks:
- the leveldb binding is non-coopertive, the node will
block while committing a block to the disk ;
- the leveldb use 'string' while internally we use 'cstruct',
this implies a lot of time-consuming 'memcpy'.
