* `lib_stdlib`: basic extended OCaml stdlib and generic data structures
* `lib_data_encoding`: almost independant 'Data_encoding'
* `lib_error_monad`: almost independant 'Error_monad'
* `lib_stdlib_lwt`: extended Lwt library
* `lib_crypto`: all the crypto stuff (hashing, signing, cryptobox).
* `lib_base`:
- basic type definitions (Block_header, Operation, ...)
- a module `TzPervasives` to bind them all and to be the
single module opened everywhere.
In the process, I splitted `Tezos_data` and `Hash` in multiple
submodules, thus removing a lot of `-open`.
The following two modules may not have found their place yet:
- Base58 (currently in `lib_crypto`)
- Cli_entries (currently in `lib_stdlib_lwt`)
The `branch` of the operation contains enough information to induce
the `net_id`, and the code of the validator/prevalidator is now mature
enough to efficiently determine the `net_id` of an incoming operation.
Operations now include a block hash in their header. Such an operation
could only be included in a successor of this block.
Furthermore, when validating a block, the economic protocol now
returns---together with the context---an integer `max_operations_ttl`.
Then, when validating a successor, the shell will fail if it contains
an operation whose header's block hash is not one the
`max_operations_ttl` predecessors of the block.
As a bonus, the shell is now able to detect and forbid replayed
operations. Then, we might decide to remove some replay
detection-mechanism that we previously implemented in the economic
protocol.
- Let the `sandbox` change the public key
- Adapt `test_basic.ml` and `test_basic.sh`
- Do not duplicate the fitness in the block header
Client:
- allow the `bootstrap` command to lookup keys in the `head` rather than
in `genesis`.
