Server crashing while being interrupted sending large chunk of data

Asked 2022-Apr-05 at 10:50

My server crashes when I gracefully close a client that is connected to it, while the client is receiving a large chunk of data. I am thinking of a possible lifetime bug as with the most bugs in boost ASIO, however I was not able to point out my mistake myself.

Each client establishes 2 connection with the server, one of them is for syncing, the other connection is long-lived one to receive continuous updates. In the "syncing phase" client receives large data to sync with the server state ("state" is basically DB data in JSON format). After syncing, sync connection is closed. Client receives updates to the DB as it happens (these are of course very small data compared to "syncing data") via the other connection.

These are the relevant files:

connection.h

Every time you execute docker-compose run you create a new container, so the gems previously installed are not available anymore.

In order to solve your problem you could run bundle install in Dockerfile, install the gems in the app folder bundle install --path vendor/bundle or mount the directory bundle uses by default to store the gems, typically /usr/local/bundle

How to make a Spring Boot application quit on tomcat failure

Asked 2022-Jan-15 at 09:55

We have a bunch of microservices based on Spring Boot 2.5.4 also including spring-kafka:2.7.6 and spring-boot-actuator:2.5.4. All the services use Tomcat as servlet container and graceful shutdown enabled. These microservices are containerized using docker.
Due to a misconfiguration, yesterday we faced a problem on one of these containers because it took a port already bound from another one.

Since you have everything containerized, it's way simpler.

Just set up a small healthcheck endpoint with Spring Web which serves to see if the server is still running, something like:

SwipeToDismiss inside LazyColumn with animation

I am trying to achieve something like this but with Jetpack Compose. In other words swipe to delete like we could do in RecyclerView with ItemTouchHelper and class DiffCallBack : DiffUtil.ItemCallback() where we could see enter - exit animations and then the list moving gracefully up or down where the item has been inserted or removed.

Recently google anounced compose Version 1.1.0-beta03. Now we have a new way on how we can animate items. They have introduced a new modifier: Modifier.animateItemPlacement(). You may find latest compose version in this link.

I will try to post an example with minimum code so that you can reproduce it and see how you could achieve a SwipeToDismiss inside LazyColumn with animation.

Asked 2021-Oct-29 at 13:08

I want to perform hyperparameter search using AzureML. My models are small (around 1GB) thus I would like to run multiple models on the same GPU/node to save costs but I do not know how to achieve this.

The way I currently submit jobs is the following (resulting in one training run per GPU/node):

ANSWER

Answered 2021-Oct-29 at 13:08

Use Run.create_children method which will start child runs that are “local” to the parent run, and don’t need authentication.

For AMLcompute max_concurrent_runs map to maximum number of nodes that will be used to run a hyperparameter tuning run. So there would be 1 execution per node.

single service deployed but you can load multiple model versions in the init then the score function, depending on the request’s param, uses particular model version to score. or with the new ML Endpoints (Preview). What are endpoints (preview) - Azure Machine Learning | Microsoft Docs

[HTCONDOR][kubernetes / k8s] : Unable to start minicondor image within k8s - condor_master not working

Asked 2021-Oct-12 at 09:51

POST EDIT

The issue is due to :

PSP (Pod security policy) By default escalation is not permit for my condor user. That is why it is not working. because the supervisord is running as root user and try to write logs and start condor collector as root and not as an other user (i.e condor)

Cause of the issue

The issue is due to :

PSP policy (Pod security policy) By default escalation is not permit for my condor user.

SOLUTION

THE BEST SOLUTION I found at the moment is to run EVERYTHING as condor user and give the permisssion to the condor users. To do so you need :

In the supervisord.conf : Run supervisor as condor user
In the supervisord.conf : run log and socket in /tmp
In the Dockerfile : Change the owner of most of folder by condor
In the deployment.yamlset the ID to 64 (condor user)

QUESTION

Server shutdown never finishes

Asked 2021-Sep-23 at 10:39

i have asynchronous gRPC server (gRPC version 1.40.X, Windows 10 x64).

When i try to shutdown the server, sometime is shutdowns gracefully and other times the thread responsible for running the gRPC gets stuck while shutdown procedure has began. the more clients spam the server the more likely it's to happen.

My shutdown procedure:

Wait for the current Que->AsyncNext to finish
I call TryToCancel on any calls that has received the AsyncNotifyWhenDone, this could be causing the issue as i can't really call this on all calls as for some the AsyncNotifyWhenDone has not yet been recived, not sure how to approach this as calling finish() is done after GOT_EVENT
I call Server->Shutdown(), here it gets stuck and the thread hangs forever.
Then Que->Shutdown()
Then DrainQue() sync function that goes trough all the remaining calls with Que->Next
Clears all call data

Here is the last trace when it happens:

Answered 2021-Sep-22 at 11:36

After some digging i have found a solution, Shutdown() has two overloads, with deadline and without deadline, the one i have been using (without deadline) just waits forever, and the one with the deadline waits only the deadline time.

so my new shutdown looks like this:
