A node that handles REST-Store requests normally acts as a
Store-client and therefore it retrieved the messages from another
Store-node.
With these changes, we allow a node with Store mounted, to retrieve
its messages. In other words, the node can act as a Store-server of
its messages.
* test_rest_store.nim: add a new test to validate that the self-node can
retrieve its messages to the REST client.
* rest/store/client.nim: add new proc to allow making a GET store
request without peerAddr.
* rest/store/handle.nim: add logic to handle requests that don't
provide peerAddr but the self/local node has Store mounted. In this case,
the self/local node will retrieve its locally stored messages.
* waku_store/self_req_handler.nim: logic to handle "store" requests
allowing the REST-store node to act as a Store-server node. The
'self_req_handler.nim' helps to bypass the store protocol and directly
retrieve the messages from the local/self node. I added this logic in
a separate file from 'protocol.nim' because it doesn't participate in
any libp2p communication.
* waku_store/protocol.nim: make 'queryHandler' attribute public so that
it can be used from the 'self_req_handler.nim' module.
The following vendors have changes but are not being updated for
the reason explained.
nim-web3: not updated because unit tests started to fail and no
straightforward solution found.
nim-toml-serialization: not updated because it introduced a breaking
change on how the --config-file attribute is parsed. The array
attributes now need a comma. For example, the following attribute
from within the config file:
pubsub-topic = [ "/waku/2/default-waku/proto" "/waku/2/testing-store" ]
... should be converted to:
pubsub-topic = [ "/waku/2/default-waku/proto", "/waku/2/testing-store" ]
and we cannot accept that breaking change
