Can we push the data to server after several hours using the current tcpclient mode?

[van basten]

The problem for our environment is the network very unstable, alwasy lost connection after one hour.

As you know, for tcpclient mode, the socket between jacoco agent and the server is always connected.

Why we do not use the tcpserver mode? since we do not know how many machines installed jacoco agent, we need use the tcpclient mode to automatically connect to the server, then we can know.

any unclear, please let me know.

Hi,

to get an better picture what actually happens: Can you please provide the Java exceptions that JaCoCo prints to syserr when the connection gets disconnected?

So what behavior do you expect from JaCoCo in tcpclientmode? Reconnect after failure?

Attached the server code. at line 154, "while (reader.read()) {" it will throw

java.net.SocketException: Connection reset

        at java.net.SocketInputStream.read(SocketInputStream.java:196)

        at java.net.SocketInputStream.read(SocketInputStream.java:122)

        at java.net.SocketInputStream.read(SocketInputStream.java:210)

        at java.io.DataInputStream.readByte(DataInputStream.java:265)

        at org.jacoco.core.data.ExecutionDataReader.read(ExecutionDataReader.java:82)

        at ExecutionDataServerWithDumpTimer$Handler.run(ExecutionDataServerWithDumpTimer.java:152)

        at java.lang.Thread.run(Thread.java:812)

as you can see, the reader keep the connection, always read the data from jacoco agent. my question is if reconnection, will the bytes that already read into the the server lost? since these data did not flush into the local file, also for the data not sent successfully will still store on the agent?

also the data should be broken, not in block.

Hi,

I was asking for the exception seen on stderr on the application under
test (where the JaCoCo agent is running).
