This adds a GrpcServiceRateMeteringConfig class that can read and
write rate metering interceptor config files, and configure
a gRPC rate metering service interceptor at startup.
This seems excessive, but we need to be able to test and tune
method rate metering without having to change hard coded, default
interceptor rate meters.
now all dao store files and request a shut down of the app.
After a restart the resource files are used. This avoids cases where a resync from
genesis got triggered (observed on seed nodes, not on desktop apps).
Seed nodes and headless apps get shut down automatically.
In case of the desktop app we show a warn popup with shutdown
button and no close button, so we enforce a shutdown to avoid
complications in case the user would continue.
This change provides a gRPC CallRateMeteringInterceptor to help protect
the server and network against being overloaded by CLI scripting mistakes.
An interceptor instance can be configured on a gRPC service to set
individual method call rate limits on one or more of the the service's
methods. For example, the GrpcOffersService could be configured with
this interceptor to set the createoffer rate limit to 5/hour, and
the takeoffer call rate limit could be set to 20/day. Whenever a
call rate limit is exceeded, the gRPC call is aborted and the client
recieves a "rate limit exceeded" error.
Below is a simple example showing how to set rate limits for one method
in GrpcVersionService.
final ServerInterceptor[] interceptors() {
return new ServerInterceptor[]{
new CallRateMeteringInterceptor(new HashMap<>() {{
put("getVersion", new GrpcCallRateMeter(2, SECONDS));
}})
};
}
It specifies a CLI can execute getversion 2 times / second.
This is not a throttling mechansim, there is no blocking nor locking
to slow call rates. When call rates are exceeded, calls are
simply aborted.
Redesign the UI
Add import/export of payout settings
Add ability to import from mediation ticket
Mediator does not need private key
User can sign using own wallet or private key
Validation of input fields
Calculate the tx fee based on inputs
Display of the generated txid & hex so it can be checked
If oen starts with --daoActivated=false there is no service
set up in one of the data store services so it never calls
the result handler and the app never starts up.

This change reduces gRPC service error handling duplication by moving
it into a @Singleton encapsulating everything needed to wrap
an expected or unexpected core api exception into a gRPC
StatusRuntimeException before sending it to the client. It also
fixes some boilerpate classes were gRPC error handling was missing.
Call flush at openOfferManager shutdown.
Remove unused method.
Force broadcaster to send out immediately, otherwise we could
have a 2 sec delay until the bundled messages sent out.
