I want to start my gwt application on dev mode using an external jetty and the gwt compilation server (using -noserver).
Starting the webserver (jetty + gwt war) with 3 permutations (user.agent=safari) takes 250s with options :
- -Dgwt.compiler.skip=true
- -Dgwt.draftCompile=true
- -Dgwt.compiler.localWorkers=8
- -Dgwt.compiler.optimizationLevel=0
and in the file MyProject.gwt.xml

Answered 2021-Dec-04 at 11:21You can avoid multiple permutation by collapsing all properties in the gwt.xml which will merge all permutations into one

I'm building a native image using the Gluonfx plugin. I'm doing this procedure inside a docker container. The image builds the 7 steps, but doing the link throws an error complaining about missing ie4uinit.exe.

Changing the base docker image to: mcr.microsoft.com/windows:1809-amd64

I have a question, assuming I have a controller with:
-Login -Index -Ventana random -LogOff
And the Ventana random opens in a new tab so we would have two tabs (Index and Ventana random), How can I make it from the Ventana random tab, when pressing the logout button, the Index tab returns to the Login screen ?

that checks if you still have a valid cookie (or whichever authentication scheme you use), perhaps you could use the visibilitychange

does exactly what it says: it starts a new session without any if or then; always check for the session ID first.
Also make sure, that the cookie-domain has been set up properly (this value might not match). For reference: setcookie()

...ANSWER
Answered 2022-Jan-13 at 09:06Depending on the GWT version you are using, GWT will usually create several JS files. IIRC and nothing is changed, you have - using the lasting GWT version - 5 permutations. These are the files with the cryptic name that the *.nochache.js
is loading.
These permutation will be loaded from the code server. And by defining files inside the Content-Security-Policy tag, you define the files which can be loaded. And because the file names always change, you have no chance to add them.
So, why not using:

QUESTION
I have a haproxy as a load balancer running in k8s with a route to a service with two running pods. I want the server naming inside haproxy to correspond to the pod names behind my service. If I'm not mistaken the following configmap / annotation value should do exactly this: https://haproxy-ingress.github.io/docs/configuration/keys/#backend-server-naming
. But for me it doesn't and for the life of me I can't find out why. The relevant parts of my configuration look like this:
controller deployment:
...ANSWER
Answered 2021-Dec-06 at 17:07Here are a few hints to help you out solving your issue.
Be sure you know the exact version of your haproxy-ingress controller:Looking at the manifest files you shared, it's hard to tell which exact version of haproxy-ingress-controller
container you are running in your cluster (btw, it's against best practices in production envs to leave it w/o tag, read more on it here).
For backend-server-naming
configuration key to be working, minimum the v0.8.1
is required (it was backported).
Before you move on in troubleshooting, firstly please double check your ingress deployment for compatibility.
My observations of "backend-server-naming=pod" behavior Configuration dynamic updates:If I understand correctly the official documentation on this configuration key, setting a server naming of backends to pod names (backend-server-naming=pod
) instead of sequences
, does support a dynamic re-load of haproxy configuration, but does NOT support as of now dynamic updates to haproxy run-time configuration to server names at backend section (it was explained by haproxy-ingress author here, and here)
It means you need to restart your haproxy-ingress controller instance first, to be able to see changes in backend's server names reflected at haproxy configuration, e.g. situations when new Pod replicas appear or POD_IP changed due the Pod crash (expect addition/updates of server entries based on sequence naming).
Ingress Class:I have tested successfully (see test below) the backend-server-naming=pod
setting on v0.13.4
with classified Ingress type, based on ingressClassName
field , rather than deprecated annotation kubernetes.io/ingress.class
, as in your case:
I'm not claiming your configuration won't work (it should too), but it's important to know, that dynamic updates to configuration (this includes changes to backend configs) won't happen on unclassified Ingress resource or wrongly classified one, unless you're really running v0.12
or newer version.

My goal is to use an iOS app written in SwiftUI to connect with AgoraRtcEngineKit. I want to create an app that is audio-only and allows a host to broadcast audio and allows listeners to listen in.
