QUESTION
Lately the more I read about memory order in C++, the more confusing it gets. Hope you can help me clarify this (for purely theoretic purposes). Suppose I have the following code:
...ANSWER
Answered 2022-Mar-15 at 14:43Neither assertion can ever fail, thanks to ISO C++'s "release sequence" rules. This is the formalism that provides the guarantee you assumed must exist in your last paragraph.
The only stores to val are release-stores with the appropriate bits set, done after the corresponding store to f1 or f2. So if thread_3 sees a value with 1 bit set, it has definitely synchronized-with the writer that set the corresponding variable.
And crucially, they're each part of an RMW, and thus form a release-sequence that lets the acquire load in thread_3 synchronize-with both CAS writes, if it happens to see val == 3.
(Even a relaxed RMW can be part of a release-sequence, although in that case there wouldn't be a happens-before guarantee for stuff before the relaxed RMW, only for other release operations by this or other threads on this atomic variable. If thread_2 had used mo_relaxed, the assert on f2 could fail, but it still couldn't break things so the assert on f1 could ever fail. See also What does "release sequence" mean? and https://en.cppreference.com/w/cpp/atomic/memory_order)
If it helps, I think those CAS loops are fully equivalent to val.fetch_or(1, release). Definitely that's how a compiler would implement fetch_or on a machine with CAS but not an atomic OR primitive. IIRC, in the ISO C++ model, CAS failure is only a load, not an RMW. Not that it matters; a relaxed no-op RMW would still propagate a release-sequence.
(Fun fact: x86 asm lock cmpxchg is always a real RMW, even on failure, at least on paper. But it's also a full barrier, so basically irrelevant to any reasoning about weakly-ordered RMWs.)
QUESTION
Today i have got this email:
Last July, we announced Advertising policy changes to help bolster security and privacy. We added new restrictions on identifiers used by apps that target children. When users choose to delete their advertising ID in order to opt out of personalization advertising, developers will receive a string of zeros instead of the identifier if they attempt to access the identifier. This behavior will extend to phones, tablets, and Android TV starting April 1, 2022. We also announced that you need to declare an AD_ID permission when you update your app targeting API level to 31 (Android 12). Today, we are sharing that we will give developers more time to ease the transition. We will require this permission declaration when your apps are able to target Android 13 instead of starting with Android 12.
Action Items If you use an advertising ID, you must declare the AD_ID Permission when your app targets Android 13 or above. Apps that don’t declare the permission will get a string of zeros. Note: You’ll be able to target Android 13 later this year. If your app uses an SDK that has declared the Ad ID permission, it will acquire the permission declaration through manifest merge. If your app’s target audience includes children, you must not transmit Android Advertising ID (AAID) from children or users of unknown age.
My app is not using the Advertising ID. Should i declare the AD_ID Permission in Manifest or not?

QUESTION
I have a server to handle events, this server has a mutex lock and a events table(map structure). When the server receives a new event, it will acquire lock to prevent data race, store this event in the events table, and start a goroutine to monitor this event has done. If I run the program with -race flag, it will output data race.
ANSWER
Answered 2022-Feb-26 at 03:47As per the comments your code attempts to read and write to a map simultaneously and, as per the go 1.6 release notes:
if one goroutine is writing to a map, no other goroutine should be reading or writing the map concurrently
Looking at your code there appears to be no need for this. You can create the channels in advance; after they are created you are only reading from the map so there is no issue:

I am trying to access my azure keyvault i have setup from my web app which due to legacy cannot be registered in azure.
I have for now via connected services "connected" the application with key vault, which then modified the web.config and installed a bunch a nuget files.
When I now try to get the secret i have stored in my azure key vault via
...ANSWER
Answered 2022-Feb-15 at 09:55how do i access my connected services, without actually storing the credentials of accessing the azure key vault?
- Use Azure AD Managed Service Identity to access Key Vault from all environments without storing any credentials in the app.
- Managed Identity provides Azure services with an automatically managed identity in Azure Active Directory .
- It helps to authenticate to any service that supports AAD authentication without maintaining credentials in your code.
- It is a great feature from a security perspective because credentials are not accessible to you.
- Managed identities can be used without any additional cost.
Refer steps to read a secret stored in an Azure Key Vault instance and Use a managed identity to connect Key Vault to an Azure web app in .NET
how do i manage two key vaults within one solution (one for dev env and one for prod env)?

QUESTION
I have one old Azure Functions project (v3). It contains several timer triggered functions. They stopped working on VS2022. You can see the logs below. If I create a new Functions project via VS2022, it will work fine. Looks like Azurite also starts up fine. Setting "AzureWebJobsStorage" equals "UseDevelopmentStorage=true". What can I do?
...ANSWER
Answered 2022-Jan-06 at 12:33Created the Azure Functions v3 Project in Visual Studio 2019 along with the azurite extension to the project and running locally:
Same Code opened in VS 2022 and run the function locally:
As given in the Microsoft Documentation, Azurite is automatically available with the VS 2022.
When you open the Azure Functions v3 project (earlier created in VS 2019) in VS 2022 now, it might show this messages in the output dialog box after loading the dependencies:
Still, the Azure Storage Emulator is required to run any azure functions project in the Windows, it needs to be installed in the system.
Make sure the Azure Storage Emulator is installed and the azurite is a future storage emulator platform included with VS 2022. If you're using earlier Visual Studio, you'll need to install Azurite by using either Node Package Manager, DockerHub, or by cloning the Azurite github repository given in the following documentation.

ANSWER
Answered 2022-Jan-12 at 22:30std::memory_order_acq_rel is not required.
Mutex synchronization is between 2 threads.. one releasing the data and another acquiring it.
As such, it is irrelevant for other threads to perform a release or acquire operation.
Perhaps it is more intuitive (and efficient) if the acquire is handled by a standalone fence:

QUESTION
I want to recycle the message object of protobuf to reduce GC consumption at runtime,but I'm not sure whether it's safe.The sample code for testing is as follows：
test.proto
...ANSWER
Answered 2022-Jan-07 at 17:30The code you show is safe. Pooling like this becomes "unsafe" when references to objects are held after they are put into the pool. You risk race conditions or strange bugs. So it also depends on the code that uses your objects.
The protocol buffers library and gRPC libraries don't hold on to references to protobuf objects, as far as I know. Doing so would break a lot of code since such libraries have no way of knowing when it would be safe to reuse.
So as long as you make sure that your own code doesn't use objects after they are put in the pool, you should be good.
QUESTION
I would like to know whether there exists in Julia something which would be rougly equivalent to the rgl package in R language; i.e., a library allowing for a dynamic/interactive representation of 3D plots, 3D surfaces, etc.
A bit of context: if you're studying, for example, morphometrics, you regularly end up with files in PLY format, or another format produced by 3D scanners. In R, you can for instance visualize (in an interactive way) easily a 3D surface acquired by such a scanner (here, a set of molars):
Do we have currently a similar feature in Julia? If so, which library should I use?
Thanks!
...ANSWER
Answered 2022-Jan-06 at 22:13Makie.jl, specifically via either the GLMakie.jl or WebGLMakie.jl backends, is a good option for interactive plots. For instance, the following example from the BeautifulMakie gallery

Install acquire
You can use acquire like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
