ANSWER
Answered 2022-Apr-01 at 19:21if you go to the missing library's Github page, you see that it was available only through jcenter, and since jcenter is down, you need to clone the library and build it yourself and put it on the classpath.
QUESTION
I'd like to make a function with both sync and coroutine version, without using template specialization, i.e. with an if constexpr.
This is the function I wrote:
...ANSWER
Answered 2022-Mar-11 at 03:51The standard explicitly says this is not possible. As per Note 1 in stmt.return.coroutine#1
... A coroutine shall not enclose a return statement ([stmt.return]).
[Note 1: For this determination, it is irrelevant whether the return statement is enclosed by a discarded statement ([stmt.if]). — end note]
So you won't be able to return from a coroutine even if it's in a discarded statement. You can specialize the function template instead of using if constexpr.

QUESTION
I am running a Spring Boot app that uses WebClient for both non-blocking and blocking HTTP requests. After the app has run for some time, all outgoing HTTP requests seem to get stuck.
WebClient is used to send requests to multiple hosts, but as an example, here is how it is initialized and used to send requests to Telegram:
WebClientConfig:
...ANSWER
Answered 2021-Dec-20 at 14:25I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github
I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).

QUESTION
We have deployed a django server (nginx/gunicorn/django) but to scale the server there are multiple instances of same django application running.
Here is the diagram (architecture):
Each blue rectangle is a Virtual Machine.
HAProxy sends all request to example.com/admin to Server 3.other requests are divided between Server 1 and Server 2.(load balance).
Old Problem:
Each machine has a media folder and when admin Uploads something the uploaded media is only on Server 3. (normal users can't upload anything)
We solved this by sending all requests to example.com/media/* to Server 3 and nginx from Server3 serves all static files and media.
Problem right now
We are also using sorl-thumbnail.
When a requests comes for example.com/,sorl-thumbnail tries to access the media file but it doesn't exist on this machine because it's on Server3.
So now all requests to that machine(server 1 or 2) get 404 for that media file.
One solution that comes to mind is to make a shared partition between all 3 machines and use it as media. Another solution is to sync all media folders after each upload but this solution has problem and that is we have almost 2000 requests per second and sometimes sync might not be fast enough and sorl-thumbnail creates the database record of empty file and 404 happens.
Thanks in advance and sorry for long question.
...ANSWER
Answered 2021-Dec-26 at 19:53You should use an object store to save and serve your user uploaded files. django-storages makes the implementation really simple.
If you don’t want to use cloud based AWS S3 or equivalent, you can host your own on-prem S3 compatible object store with minio.
On your current setup I don’t see any easy way to fix where the number of vm s are dynamic depending on load.
If you have deployment automation then maybe try out rsync so that the vm takes care of syncing files with other vms.
QUESTION
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.

Answered 2021-Dec-17 at 08:38Since you have everything containerized, it's way simpler.
