Tkinter: How to deiconify a popup window (and give it focus)?

Asked 2021-Mar-01 at 11:34

I am on Ubuntu 20.04 and struggling with making iconify() and deiconify() work for a popup window. Currently the popup window will not deiconify() after having been iconified. Here is a minimal example:

ANSWER

Answered 2021-Mar-01 at 11:34

The grab_set method routes all the events of the application to the specified widget.

Since you have called self.grab_set() on the popup window, the main window will refuse to take any event (the button is never clicked to begin with) and so the program doesn't work.

Removing that would make it work.

QUESTION

What is the cost of having multiple subscriptions in Pulsar?

Asked 2020-Oct-31 at 19:31

What is the cost of creating multiple subscriptions on a topic? Does creating more subscriptions affect the broker, Bookkeeper or both?

I'm assuming it only adds work load to the broker but the work increased by adding another subscription is minimal since it would only have to duplicate the messages?

...

ANSWER

Answered 2020-Oct-30 at 13:24

In Pulsar, a topic (or a partition) is owned by a single Broker meaning that all reads and writes go through that broker. Brokers cache bookies entries in memory so that it can dispatch messages directly to all consumers. This will avoid a network round-trip and a possible disk read on bookies.

In addition, you should note that a broker must send data over the network for each subscription. This can lead to network saturation if you have a very high throughput.

Moreover Bookies also have a write/reach cache to reduce disk access.

QUESTION

Sumo Logic kubernetes integration requires that no Prometheus exists

Asked 2020-Oct-05 at 19:23

I am currently working on integrating Sumo Logic in a AWS EKS cluster. After going through Sumo Logic's documentation on their integration with k8s I have arrived at the following section Installation Steps. This section of the documentation is a fork in the road where one must figure out if you want to continue with the installation :

side by side with your existing Prometheus Operator
and update your existing Prometheus Operator
with your standalone Prometheus (not using Prometheus Operator)
with no pre-existing Prometheus installation

With that said I am trying to figure out which scenario I am in as I am unsure. Let me explain, previous to working on this Sumo Logic integration I have completed the New Relic integration which makes me wonder if it uses Prometheus in any ways that could interfere with the Sumo Logic integration ?

So in order to figure that out I started by executing:

ANSWER

Answered 2020-Sep-25 at 23:08

I think you most likely will have to go with the below installation option :

with your standalone Prometheus (not using Prometheus Operator)

Can you check and paste the output of kubectl get prometheus. If you see any running prometheus, you can run kubectl describe prometheus $prometheus_resource_name and check the labels to verify if it is deployed by the operator or it is a standalone prometheus.

In case it is deployed by Prometheus operator, you can use either of these approaches:

side by side with your existing Prometheus Operator
update your existing Prometheus Operator

Maven sure fail build when a test timeout is reached even when fail-on-end set to true

Asked 2020-Apr-19 at 17:45

In a multi-module maven project, I want to print the thread-dump and fail the test when a test timeout is reached. So to achieve this I have used a combination of TimedoutTestsListener and surefire listener property.

I am using Jenkins so fail-on-end is set to true so that all non-impacted tests continue to run as mentioned here.

So, is it possible to fail the build immediately only when timeout is reached and in other failure cases fail in the end?

JUnit - 4.12
Maven - 3.5
Surefire - 2.22.2
Jave - 8

This has been answered in the maven email group

to fail the build immediately when timeout is reached

This feature exists for years: http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#forkedProcessTimeoutInSeconds http://maven.apache.org/surefire/maven-failsafe-plugin/integration-test-mojo.html#forkedProcessTimeoutInSeconds

to fail the ... when someone presses abort button on the jenkins

This also exists with several alternatives (changed across the versions). See the detailed page http://maven.apache.org/surefire/maven-failsafe-plugin/examples/shutdown.html

If your Jenkins sends the SIGTERM signal into the Maven process (same as CTRL+C) then the standard input stream in process pipe becomes closed and the EOFException is caugh byt the forked JVM and shutdown is called: http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#shutdown maven.apache.org/surefire/maven-failsafe-plugin/integration-test-mojo.html#shutdown If you want to kill the JVM, you can reconfigure the default behavior.

If your Jenkins sends SIGTERM to the Maven process then enable the process checker, see more details in the documentaion: http://maven.apache.org/surefire/maven-surefire-plugin/test-mojo.html#enableProcessChecker http://maven.apache.org/surefire/maven-failsafe-plugin/integration-test-mojo.html#enableProcessChecker
