I want to programmatically detect whenever someone sends Bitcoin to some address. This happens on a local testnet which I start using this docker-compose.yml file.
Once the local testnet runs, I create a new address using
docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli getnewaddress
Let's say it returns 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181.
I put this address into the following Java code:
import org.bitcoinj.core.Address;
import org.bitcoinj.core.Coin;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.core.Transaction;
import org.bitcoinj.wallet.Wallet;
import org.bitcoinj.wallet.listeners.WalletCoinsReceivedEventListener;
public class WalletObserver {
public void init() {
final NetworkParameters netParams = NetworkParameters.fromID(NetworkParameters.ID_REGTEST);
try {
final Wallet wallet = Wallet.createBasic(netParams);
wallet.addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
wallet.addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
#Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
}
Then I start the Java application with this class.
Then I send some test Bitcoin to the address in question:
% docker exec -it minimal-crypto-exchange_node_1 bitcoin-cli sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.5
068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406
If I go to http://localhost:3002/tx/068c377bab961356ad9a3919229a764aa929711c68aefd5dbd4c7c348eef3406, I see that the transaction details.
However, the breakpoint in the listener (onCoinsReceived method) never activates.
How do I need to modify my code and/or the commands I use to send test BTC so that whenever money is received by that account, onCoinsReceived method is called? Is there a place where I can tell Wallet or NetworkParameters that I want to connect to localhost?
I am using version 0.15.10 of bitcoinj-core.
Update 1:
I modified docker-compose.yml and added following port mappings:
ports:
- "51001:50001"
- "51002:50002"
- "19001:19001"
- "19000:19000"
- "28332:28332"
Then I rewrote the init method so that I can connect to localhost and specify the port:
public class WalletObserver {
public void init() {
final LocalTestNetParams netParams = new LocalTestNetParams();
netParams.setPort(50001);
try {
final WalletAppKit kit = new WalletAppKit(netParams, new File("."), "_minimalCryptoExchangeBtcWallet");
kit.setAutoSave(true);
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning(); // I never get past this point
kit.peerGroup().addPeerDiscovery(new DnsDiscovery(netParams));
kit.wallet().addWatchedAddress(Address.fromString(netParams, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener(new WalletCoinsReceivedEventListener() {
#Override
public void onCoinsReceived(final Wallet wallet, final Transaction transaction, final Coin prevBalance, final Coin newBalance) {
System.out.println("Heyo!");
}
});
}
catch (Exception exception) {
exception.printStackTrace();
}
}
LocalTestNetParams allows to specify the port:
package com.dpisarenko.minimalcryptoexchange.logic.btc;
import org.bitcoinj.params.RegTestParams;
public class LocalTestNetParams extends RegTestParams {
public void setPort(final int newPort) {
this.port = newPort;
}
}
I tried all of the aforementioned ports in netParams.setPort(50001);.
In all cases I get the following messages after kit.awaitRunning();:

Update 1:
I tried to use network_mode: "host".
If I add it to node as in

Update 3: I assume that the root of the error is that in my Java code I try to connect to the ElectrumX server instead of the actual Bitcoin node (node in docker-compose.yml).
Update 4:
I changed docker-compose.yml as follows:

Update 5:
Someone suggested (in a now removed comment) that in the output of the application there is this Peer does not support bloom filtering message:
11:32:43.482 [NioClientManager] INFO org.bitcoinj.core.Peer - Peer{[127.0.0.1]:19000, version=70015, subVer=/Satoshi:0.19.1(bitcore)/, services=1033 (NETWORK, WITNESS, NETWORK_LIMITED), time=2021-11-06 11:32:43, height=4}: Peer does not support bloom filtering.
So I tried to fork the original image and change the bitcoin.conf file to enable Bloom filtering:
peerbloomfilters=1
When I run docker build -t mentiflectax/bitcoind-custom-regtest:latest . I get the following error message (part of remaining output can be found here):

Update 6: The correct port seems to be 19000.
If I use port 19001, I get following errors after kit.awaitRunning():

Full log output is available here.
I haven't tested your full setup with electrumx and the ethereum stuff present in your docker-compose file, but regarding your problem, the following steps worked properly, and I think it will do as well in your complete setup.
I ran with docker a bitcoin node based in the ulamlabs/bitcoind-custom-regtest:latest image you provided:
docker run -p 18444:19000 -d ulamlabs/bitcoind-custom-regtest:latest
As you can see, I exposed the image internal port 19000 as the default port for RegTestParams, 18444. From the point of view of our client, with this setup, basically it will look like as if we were running the bitcoin daemon in the host. Using your LocalTestNetParams class and providing the port 19000 as you indicated should do the trick as well.
Then, according to the feedback you provided in the question, I manually edited the daemon configuration of the bitcoin node in /root/.bitcoin/bitcoin.conf using bash and vi:
docker exec -it 0aa2e863cd9927 bash
And included the following configuration:
peerbloomfilters=1
After restart the container, I got a new address:
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest getnewaddress
Let's assume that the new address is the one you provided in the question:
2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181
Then, as suggested in the Bitcoin documentation, in order to avoid an insufficient funds error, I generated 101 blocks to this address:
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest generatetoaddress 101 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181
I used generatetoaddress and not generate because since Bitcoin 0.19.0 the option is no longer valid.
Next, I prepared a simple Java program, based in the information you provided and this example from the Bitcoinj library documentation:
import java.io.File;
import org.bitcoinj.core.Address;
import org.bitcoinj.core.NetworkParameters;
import org.bitcoinj.kits.WalletAppKit;
import org.bitcoinj.params.RegTestParams;
public class Kit {
public static void main(String[] args) {
Kit kit = new Kit();
kit.run();
}
private synchronized void run(){
NetworkParameters params = RegTestParams.get();
WalletAppKit kit = new WalletAppKit(params, new File("."), "walletappkit-example");
kit.connectToLocalHost();
kit.startAsync();
kit.awaitRunning();
kit.wallet().addWatchedAddress(Address.fromString(params, "2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181"));
kit.wallet().addCoinsReceivedEventListener((wallet, tx, prevBalance, newBalance) -> {
System.out.println("-----> coins resceived: " + tx.getTxId());
});
while (true) {
try {
this.wait(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
I used a simple while loop to keep the problem running; of course, if will be probably unnecessary in an actual setup as it seems you are using Spring Boot.
Then, if you send some bitcoins to this address:
docker exec -it 0aa2e863cd9927 bitcoin-cli -regtest sendtoaddress 2N23tWAFEtBtTgxNjBNmnwzsiPdLcNek181 0.00001
0f972642713c72ae0fe03fe51818b9ea4d483720b69b90e795f35eb80a587c26
The listener should be invoked:

There is still a problem you mentioned that I haven't had the opportunity to test, and it is creating a new Docker image in which the peerbloomfilters configuration would be configured properly without modifying the actual container state. I think the compilation problem you indicated could be related to this issue, basically, that the container didn't have enough resources to perform the process. If you are using macOS and Docker for Mac, try tweaking the amount of memory available to your containers, it may be of help. A change in the base alpine image used can motivate the problem also. I will try digging into the issue as well.
I have enabled checkpoint in flink 1.12.1 programmatically as below:
int duration = 10 ;
if (!environment.getCheckpointConfig().isCheckpointingEnabled()) {
environment.enableCheckpointing(duration * 6 * 1000, CheckpointingMode.EXACTLY_ONCE);
environment.getCheckpointConfig().setMinPauseBetweenCheckpoints(duration * 3 * 1000);
}

But it is failing with following error:

If I remove/disable checkpoint, everything works normally. I have checkpoint requirement because, if my pod, gets restart, data which is being handled by earlier run gets reset.
Can somebody direct, how this can be addressed?

Any idea about the issue ?
The most likely reason is that you are referencing objects in the region from where the config was saved from.
Is this the first EB application / environment in the new region?
If it is, it's worth first creating a test application and environment, using the features you want ... that will give EB a chance to create all the region specific behind-the-scenes magic it relies on.
I changed the MQIVP sample in MQ with a server connection channel of my own local.server.con and it is working fine. But I tried connecting to the same channel with PCFMessageAgent and the connection is failing with errors in MQ log. What is the relation between my channel and SYSTEM.DEFAULT.MODEL.QUEUE which gives the error.

EXPLANATION:
The channel program running under process ID 8004(7988) for channel
'local.server.con' ended abnormally. The host name is '10.40.1.16'; in some
cases the host name cannot be determined and so is shown as '????'.
ACTION:
Look at previous error messages for the channel program in the error logs to
determine the cause of the failure. Note that this message can be excluded
completely or suppressed by tuning the "ExcludeMessage" or "SuppressMessage"
attributes under the "QMErrorLog" stanza in qm.ini. Further information can be
found in the System Administration Guide.

You need to go and read up on MQ permissions (i.e. authorizations). It is best to do permissions on the group rather than principle (UserId).
setmqaut -m {QM_NAME} -n SYSTEM.ADMIN.COMMAND.QUEUE -t queue -g {GROUP} +put +inq +dsp
setmqaut -m {QM_NAME} -n SYSTEM.DEFAULT.MODEL.QUEUE -t queue -g {GROUP} +get +inq +dsp
There is no relation between channels and model queues.
But I think, that the PCFMessageAgent is trying to create a dynamic queue to use as a ReplyToQ to receive responses, and it seems it tries to create the dynamic queue by opening the SYSTEM.DEFAULT.MODEL.QUEUE.
I've implemented an HTTP service based on the HTTP server example as provided by the netty.io project.
When I execute a GET request to the service URL from command-line (wget) or from a browser, I receive a result as expected.
When I perform a load test using ApacheBench ab -n 100000 -c 8 http://localhost:9000/path/to/service, experience no errors (neither on service nor on ab side) and see fair numbers for request processing duration.
Afterwards, I set up a test plan in JMeter having a thread group with 1 thread and a loop count of 2. I inserted an HTTP request sampler where I simply added the server name localhost, the port number 9000 and the path /path/to/service. Then I also added a View Results Tree and a Summary Report listener.
Finally, I executed the test plan and received one valid response and one error showing the following content:

As I have a similar service already running which receives and processes web tracking data which shows no errors, it might be a problem within my test plan or JMeter .. but I am not sure :-(
Did anyone experience similar behavior? Thanks in advance ;-)
Issue can be related to Keep-Alive management.
Read those:
https://bz.apache.org/bugzilla/show_bug.cgi?id=57921
https://wiki.apache.org/jmeter/JMeterSocketClosed
So your solution is one of those:
If you're sure it's a keep alive issue:
Try jmeter nightly build http://jmeter.apache.org/nightly.html:
Download the _bin and _lib files
Unpack the archives into the same directory structure
The other archives are not needed to run JMeter.
And adapt the value of httpclient4.idletimeout
A workaround is to increase retry or add connection stale check as per :
https://wiki.apache.org/jmeter/JMeterSocketClosed
