QUESTION
I using TCPIP to get data from a controller. When using TCPIP to receive data, i only can get the first line on data which mean the data length is 1514, but the another line of data which is length 174 are unable to get from TCPIP Client protocol at C#. May need you guys to advise on this.
Picture Below is used Wireshark to trace the TCPIP data.
Below picture is the method used to receive data from TCPIP Client Protocol.
Thanks.
Here is how I approach to connect and get data from TCPIP. Please correct me if that was a mistake.
...ANSWER
Answered 2022-Mar-31 at 06:09For TCP/IP, when you specify the number of bytes to receive in a Receive method, it is an upper limit, not an absolute number of bytes. If you receive less than the requested number of bytes, you need to do another read and combine the results together into the data you want. This is why the Receive method allows you to specify the index into the array to put the received data. For example:

I'm trying to build two programs that can interact with each other over network using JSON RPC.
It currently works fine for primitive types like integers, but Custom Classes/Objects get always returned as null.
This is the method that fetches the data from the database. The data gets collected correctly and no field is null.

QUESTION
I am developing an Android app with Kotlin, Jetpack Compose - for UI, and Retrofit - for making requests to a REST API server made by me. I am a beginner at Kotlin Coroutines, Compose and Retrofit and I am facing the following issue:
- immediately after the HomeActivity starts, the assignSyncer() function in the HomeViewModel, which contains a coroutine that retrieves a Syncer object from the server via Retrofit, is called two times instead of once.
It does not produce any observable difference for the mobile user, but the server receives the request two times, and it is not ideal to burden the server and the network. I put some prints in the code and, indeed, the Retrofit call is executed two times - the code flows this way:
- enters HomeActivity (CP_1),
- enters assignSyncer() (CP_2),
- launches coroutine (CP_3),
- getInstance() is called (CP_4),
- and the instance is created (CP_5) and the REST API call is made.
But immediately after, again,
- CP_2,
- CP_3,
- and CP_4 are gone through.
The Syncer object is received correctly and it is integrated into the composable objects, even though this process happens twice.
Therefore, is it something I am doing wrong?
Here's some relevant code:
The HomeActivity which uses Compose:
...ANSWER
Answered 2021-Nov-22 at 19:47Your call to homeViewModel.assignSyncer() is a part of composition. So whenever there is a recomposition this function gets called. For such side effects, you should use proper effect handlers. Like here you want to call this function only once so you can use LaunchedEffect (refer linked doc for detailed information about these functions).
QUESTION
I'm trying to get data from an API, but it somehow gets weird data, I've tried many things and i don't know what else I could do.
...ANSWER
Answered 2021-Nov-18 at 15:07The problem could be that multi-byte sequences have arrived split into different chunks, and it doesn't make sense to turn any single chunk into a string by itself because some of the bytes of a character is in one chunk and the other bytes of that character are in the next chunk.
To get around this, just accumulate the incoming data chunks by keeping the the buffers they originally arrived in, and concatenate all the buffers (chunks) into a single buffer before turning them into a string.
Instead of data = '' do chunks = [], and instead of data += chunk; do chunks.push(chunk) and then in your 'end' handler, do data = Buffers.concat(chunks).toString('utf8').

QUESTION
when I want to build my Alpine Docker I get an error when I define specific python version.
My Dockerfile:
...ANSWER
Answered 2021-Feb-19 at 22:08The error from apk is since that specific Python 3 version is not found in the Alpine repositories.
python3=3.6.9-r3 currently only lives in the Alpine 3.9 main repository:
https://pkgs.alpinelinux.org/package/v3.9/main/x86/python3
The python:3-alpine image seems to be based on Alpine 3.13, the latest. Therefore, the package for 3.6.9 is not to be found.
For installing that specific version, you have to tell apk to use that 3.9 repository (if you're not on Alpine 3.9):

QUESTION
I have a very weird behavioural difference when my Java program is run with Java 8 and Java 11.
I am using the MSGraph API (1.7.0) to make several calls to the Onedrive APIs. To make these calls, I am using 4 parallel threads for sync a lot of files (around 1000) on my hard disk.
When I execute the program with Java 8, I get no exceptions. When I execute it with java 11, I get a Socket Timeout Exception in around the 60% of the calls.
To configure the IGraphServiceClient, I am using the default configuration. As far as I am concerned, the HTTP Provider is OKHttp3 in this case.
Has anybody experienced anything like this?
[UPDATE-1]
These are the environments I have tested:
- Oracle's JDK 1.8.0_192 --> Perfect. Not an error in around 400 calls
- Openjdk 11.0.7 and Oracle's jdk 11.0.3 --> tons of Sokcet Timeout Exceptions
Hereby you have the stacktrace:
...ANSWER
Answered 2020-May-26 at 21:49OkHttp on JDK9 (or JDK8 252+), will negotiate HTTP/2 by default. There is a high chance it is related to this change.
Try building a client without HTTP/2 and see if you still get this problem.
