How do I make invalidate an entry and return its value from a Caffeine Cache?

You should use cache.asMap().remove(key) as you suspected. The other call delegates to this, but does not return the value because that is not idiomatic for a cache.

The Cache interface is opinionated for how one should commonly use a cache, while the asMap() view is more raw to allow for advanced operations. For example, you generally wouldn't iterate over a cache (e.g. memcached doesn't allow this), but if you need to then the Map provides that support. All calls flow into the same backing structure, so there will be no inconsistency. The APIs merely try to nudge users towards best practices, but strive to not block a developer from getting their work done safely and correctly.

PowerShell: Invoke-WebRequest - Cannot validate argument on parameter 'Uri'

Asked 2021-Jun-15 at 21:03

I'm trying to help a developer who is trying to harden a web server against server-side request forgery. In short, I've wrote a script that sends a "forged" HTTP request which we will use to test against the server until it is configured to not respond to such manipulated requests. I'm getting an error on Invoke-WebRequest: "Cannot validate argument on parameter 'Uri'" and while I've tried a ton of different combos of the below code I cannot get it to fly. Any thoughts?

Starting with 6.4 RC5 (which is the version you run as of this writing and should provide this in your original post):

The collection of thymeleaf user interface template pages are no longer found in the context root of the web application resources. Instead, they are organized and grouped into logical folders for each feature category. For example, the pages that deal with login or logout functionality can now be found inside login or logout directories. The page names themselves remain unchecked. You should always cross-check the template locations with the CAS WAR Overlay and use the tooling provided by the build to locate or fetch the templates from the CAS web application context.

https://apereo.github.io/cas/development/release_notes/RC5.html#thymeleaf-user-interface-pages

Please read the release notes and adjust your setup.

What happens to the CPU pipeline when the memory with the instructions is changed by another core?

I'm trying to understand how the "fetch" phase of the CPU pipeline interacts with memory.

Let's say I have these instructions:

...

ANSWER

Answered 2021-Jun-15 at 16:34

It varies between implementations, but generally, this is managed by the cache coherency protocol of the multiprocessor. In simplest terms, what happens is that when CPU1 writes to a memory location, that location will be invalidated in every other cache in the system. So that write will invalidate the line in CPU2's instruction cache as well as any (partially) decoded instructions in CPU2's uop cache (if it has such a thing). So when CPU2 goes to fetch/execute the next instruction, all those caches will miss and it will stall while things are refetched. Depending on the cache coherency protocol, that may involve waiting for the write to get to memory, or may fetch the modified data directly from CPU1's dcache, or things might go via some shared cache.

Unity Package Manager Error: zlib: incorrect data check. No packages loaded

Asked 2021-Jun-15 at 14:32

Error when loading Image

I have now gotten this error multiple times after accessing my project on a different computer then coming back to my laptop.

I tried finding a solution online to this error but could not find anything about this specific error. I cleared the unity cache and other project settings to try and fix this issue based on similar issues.

Edit
Moved answer from the question to the posted answer.

ANSWER

Answered 2021-Jun-15 at 14:32

After doing some tests I found that this problem can be solved fairly easily. To fix/go around this issue,

Go to the location of the bundled package that is listed in the error. There will be a bunch of .tgz files.
Copy the .tgz file that is showing in the error message (in this instance it is com.unity.adaptiveperformance-2.1.1.tgz).
Navigate then to: C:\Users\\AppData\Local\Unity\cache\npm\packages.unity.com
Make a folder in this directory named without the version number and extension (folder name in this instance would be com.unity.adaptiveperformance).
Enter this folder and create a sub-folder with the given version number (this instance 2.1.1).
Paste the .tgz file that you copied before into this folder and rename it package.tgz.
Open the .tgz file or extract the file to the version number folder you created. Image of final directory path and files

My understanding of this problem is that after syncing data between my main computer and my laptop made it to where the package data would be regenerated on my laptop. When this occurred, my laptop would not be able to extract a given package from unity's compressed packages for the editor. This caused me to have to manually extract that given package into the unity cache. (Note: syncing was done through onedrive)

After you have added the file, close and relaunch the unity project and it should pass this error without issue. I thought I should post this issue and the solution I found for others that may find themselves with this same issue.

QUESTION

react-pdf: use PDFDownloadLink asynchronously without blocking the rest of the application

Asked 2021-Jun-15 at 13:58

I'm using PDFDownloadLink from the react-pdf package to generate a PDF on the fly in my application and allow the user to download a report based on data being passed to the component that generates the PDF document. However, there are more than 400 pages that need to be rendered in this PDF, and this operation blocks the main thread for a few seconds. Is there any way to make this operation asynchronous, so the rest of the application will continue to function while the PDF is being generated? Also I would like to be able to cache the results, since the data being passed to the component can come from about 8 different arrays of data, which don't change very much, so switching between these arrays I would rather not to have to render the PDF all over again if the PDF for that given array has already been generated once before... I'm guessing the blob data needs to be stored somewhere, perhaps localStorage?

I finally found the answer to this in an issue on github which addresses this exact problem:

Is your feature request related to a problem? Please describe. It is an improvement. At the moment, if you use 'PDFDownloadLink' the PDF is being generated as the component loads.

Describe the solution you'd like It is not mandatory, but having multiple heavy PDFs ready to be downloaded wouldn't be the best approach since not every user will need it.

Describe alternatives you've considered I've used pdf() function to generate the blob and file-saver lib to download it:

QUESTION

Can different network be the cause for UnreachableBrowserException exception?

Asked 2021-Jun-15 at 13:57

I have two grid setup's

Local grid setup (hub and nodes are running in my local machine) and my local machine connected to network#1
VM grid setup (hub and nodes are running in my virtual machine) and my virtual machine connected to network#2

When I execute the scripts I need to pass the IP address as a parameter. Here, I can run my scripts successfully in local machine(code is available in local machine) by passing the network#1 IP address but if I pass the network#2 IP address (VM IP address) to local machine then I am getting below exception,

org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
