Problem: Editorconfig was configured to strip trailing whitespace in all
file types. This is generally a good thing, but when interactive
rebasing with Git and editing the contents of a commit, trailing
whitespace is significant on blank lines and must be preserved in order
for edits to be applied cleanly.
Solution: Update Editorconfig to exclude *.diff from the strip
whitespace rule, as interactive rebasing edits are done in a temporary
file with a '.diff' suffix.
This commit introduces a new `grpc` module including the following key
types:
- BisqGrpcServer: The API implementation itself, along with generated
gRPC Response/Reploy types defined in grpc/src/main/proto/grpc.proto.
- BisqGrpcServerMain: A 'headless' / daemon-like entry point for
running a Bisq node without the JavaFX desktop UI.
- BisqGrpcClient: A simple, repl-style client for the API that allows
the user to exercise the various endpoints as seen in the example
below.
In the `desktop` module, the BisqAppMain class has been modified to
start a BisqGrpcServer instance if the `--desktopWithGrpcApi` option has
been set to `true`.
In the `core` module, a new `CoreApi` class has been introduced
providing a kind of comprehensive facade for all Bisq functionality to
be exposed via the RPC API.
How to explore the proof of concept:
1. Run the main() method in BisqAppMain providing
`--desktopWithGrpcApi=true` as a program argument or alternatively, run
the main() method in BisqGrpcServerMain, where no special option is
required. In either case, you'll notice the following entry in the log
output:
INFO bisq.grpc.BisqGrpcServer: Server started, listening on 8888
2. Now run the main() method in BisqGrpcClient. Once it has started up
you are connected to the gRPC server started in step 1 above. To
exercise the API, type `getVersion` via stdin and hit return. You
should see the following response:
INFO bisq.grpc.BisqGrpcClient - 1.2.4
Likewise, you can type `getBalance` and you'll see the following
response:
INFO bisq.grpc.BisqGrpcClient - 0.00 BTC
and so forth for each of the implemented endpoints. For a list of
implemented endpoints, see BisqGrpcServer.start().
Note once again that the code here is merely a proof of concept and
should not be considered complete or production-ready in any way. In a
subsequent commit, the `--desktopWithGrpcApi` option will be disabled in
order to avoid any potential production use.
The content of this commit is the result of squashing a number of
commits originally authored by chimp1984 in the `chimp1984` fork's `grpc`
branch.
