The new version of ocplib-resto :
- uses jbuilder ;
- is functorized over `Json_encoding` rather than `Json_repr` ;
- handles query parameters ;
- handles HTTP methods (GET, POST, DELETE, PUT, PATCH) ;
- replaces `custom_service` by a more generic trailer argument ;
- replaces generic answer `(code, body)` by a more ad-hoc sum type
(allowing distinct encoding for success and error) ;
- includes a minimal HTTP-server based on Cohttp
(includings CORS and media type negotiation).
- adds a function `Directory.transparent_lookup` to lookup/call
a service handler without serializing the various parameters
(path, query, request body).
As a first consequences in Tezos, this patch allows binary
communication between the client and the node.
This patch tries to be minimal inside the tezos source code and
therefore it introduces a minimal compatibility layer in
`RPC.ml`. This code should be removed as soon as possible.
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.
The single validation module is split in multiple (simpler)
modules. In the process, we introduce one "validation worker" per
peer. This worker handle all the `New_head` and `New_branch`
advertised by a given peer. For so, it sends "fetching request" and
"validation request" to respectively the `Distributed_db` and and the
`Block_validator`. These two global workers are responsible of the
'fair' allocation of network and CPU ressources amongst the connected
'peers'.
The invariant of the `clear` function was not properly inforced by the
module interface. This patch remove the inappropriate invariant and
properly rename the function.
New category:
- node.distributed_db.p2p_reader
log all incoming message, from any peer (debug)
- node.distributed_db.scheduler.*
log the request scheduler of the given ressources (notice/debug),
where '*' might be:
- Operation_hash (individual operation)
- Block_hash (block header)
- operation_hashes (aggregated operation_hashes of a block)
- operations (aggregated operations of a block)
- Protocol_hash (protocol)
