QUESTION
I have master-slave (primary-standby) streaming replication set up on 2 physical nodes. Although the replication is working correctly and walsender and walreceiver both work fine, the files in the pg_wal
folder on the slave node are not getting removed. This is a problem I have been facing every time I try to bring the slave node back after a crash. Here are the details of the problem:
postgresql.conf on master and slave/standby node
...ANSWER
Answered 2021-Jun-14 at 15:00You didn't describe omitting pg_replslot during your rsync, as the docs recommend. If you didn't omit it, then now your replica has a replication slot which is a clone of the one on the master. But if nothing ever connects to that slot on the replica and advances the cutoff, then the WAL never gets released to recycling. To fix you just need to shutdown the replica, remove that directory, restart it, (and wait for the next restart point to finish).
Do they need to go to wal_archive folder on the disk just like they go to wal_archive folder on the master node?
No, that is optional not necessary. It is set by archive_mode = always
if you want it to happen.
QUESTION
Just to get it right, I would like to have your opinion if I am right with my imagination of how the dataflow is between a C# programm calling a C++ dll with delegates as parameter.
- The System gives memory to the C# program
- The C# Program loads the .dll and gives some of its space to the C++ dll. In this space there will be no C# Garbage Collection, only if the .dll is unloaded and then there can be freed the whole space.
- A C++ function is called. The specific Function has a delegate as parameter. We dive into the C++ memory area and declare some variables. The C++ function will somewhere in its Code call the C# delegate.
- The C# delegate operates on the C# Memory and will have a copy of its input parameters in the C# memory, if they are native types or a reference to the variables in the C++ memory, if it is a complex type. If we have native types I can just save it into the C# world and all will be fine. But if it is a reference and I just save it into my C# memory, I will get undefined behaviour, if I end my C++ function, because the variables will get out of scope and will be destroyed.
- The C# function ends and we get the returnvalue in C++ as copy (or a pointer to the returnvalue, if it is a complex type, the pointer will point into the C# memory)
- the C++ function ends and the used memory of the C++ function is released
Am I right with this?
...ANSWER
Answered 2021-Jun-09 at 08:31This should be described in the documentation for the marshaller
if they are native types or a reference to the variables in the C++ memory, if it is a complex type. If we have native types I can just save it into the C# world and all will be fine. But if it is a reference and I just save it into my C# memory, I will get undefined behavior, if I end my C++ function, because the variables will get out of scope and will be destroyed
My understanding is that the marshaller will either convert complex types to structs, or pointers (IntPtr). Structs are passed by value, so you would have a copy in managed memory (probably on the stack). Pointers would need unsafe code to access, so you would be responsible for handling these safely.
C++ as copy (or a pointer to the returnvalue, if it is a complex type, the pointer will point into the C# memory)
There is not really a way a managed function can return a pointer to managed memory in a safe way. To create a pointer you would need to fix the object to preventing the GC from moving it, but fixing is scoped, so it would not work for return values.
I personally consider the marshalling rules a bit complicated, and I would prefer to keep any p/Invoke simple, if for no other reason than to avoid questions about safety. For more complicated interoperability between c# and c++ I would suggest c++/cli. This allow you to do type conversion yourself, and adds a whole host of tools you can use to ensure correct functioning.
QUESTION
Sorry if the question is unclear or the answer obvious, I have to work on this project for school without having had a deep dive in c# and WPF.
I built a list view with checkboxes following this
I would like to simply get the list of all items (category) with a thicked checkbox when I click the button "Filter categories".
I found kind of similar questions with answers involving using code behind which I can't do.
...ANSWER
Answered 2021-Jun-08 at 14:14Should I add a bool property display in the "category" model and bind it to the checkbox?
Yes.
If yes, I still don't know how to get a list of all thicked items.
Just filter them out from the courseCategories
collection, for example using LINQ:

As u can see, my curtain is open every time u first run up the site. The curtain opens when u click Account and closes when u click it again. I need to have the curtain closes and open only when someone clicks Account. Then, I need also that, when u click Account, the world became of the gradient of the background and the background himself get white.
...ANSWER
Answered 2021-Jun-05 at 16:45On initial load, as the height of ac_curtain
is not defined, hence it has a default height and thus it gets displayed on the initial load. Please add height: 0
in the ac_curtain
class.
QUESTION
I have an app in production environment with remote logging of the client side errors. I get now and then this Firebase (firestore) security rules error:
FirebaseError: Missing or insufficient permissions.
When I check on the rules console, I can see that those errors are actually reported, but I have now way to see which rule specifically has provoked the error. I have no way to trace back which part of my client side code is triggering this error.
Any suggestions to find it? Any log from the Google console where I can dive?
...ANSWER
Answered 2021-Jun-02 at 14:56In production no details are logged anywhere about what specific part of your security rules failed.
The two most common approaches to finding this are based on "replaying" the scenarios in your app:
- In the rules playground in the Firebase console.
- In the emulator suite, and its
debug
function.
In both cases I find it easiest to use a divide and conquer approach, enabling/disabling large chunks of my rules at a time to zoom in on what check might be rejecting the operation.

I have div containing svg like this i want to do something when this dive click event how can i do
Code
...ANSWER
Answered 2021-Jun-01 at 14:49You are on the right lines.
There are several ways to attach an Event Listener like onclick
but a standard unobtrusive approach in modern Javascript would be to:
- grab the DOM element
- declare a named function
- apply the
.addEventListener()
method to the element, with the named function as callback

QUESTION
Use-case description:
I've a use case wherein, we need to create a VM in azure using the existing VHD Uri available in storage account & the same ARM template should have the feasibility to join to domain. At the present currently tried working & executing the ARM template which has only flexibility of using the existing VHD Uri and creating a VM (this Uri will act as "OsDiskVhdUri") & another template has only the ability to create new VM and join to domain these are working on standalone basis.
Key highlighters:-
- Need a template which has both "OsDiskVhdUri" & domain join parameters.
- Template reference should be "OsDiskVhdUri", because when i tried integrating both templates & troubleshooting - Image reference related errors are there on while deployment.
- The very important point, was - the ARM template while blueprint assignment asks for OsDiskVhdUri parameter and although I give the Uri for creating the VM, with the below template, it doesn't seems to take that Uri" instead it creates a NEW VM every time and attaches to domain.
- Deployment method is blueprint in Azure.
Error:- type 'Template' failed to deploy due to the following error: Template deployment failed with error [ { "message": "Could not find member 'osDiskVhdUri' on object of type 'ImageReference'. Path 'properties.storageProfile.imageReference.osDiskVhdUri', line 1, position 237." }
Exhausted all methods finding still deeper dive into it & any guidance on this will be highly appreciated!!
Code for reference:

My chart was rendering last night. Now, it will sometimes render fully, sometimes partially, or often not at all. I am getting no errors in the dev tools. I copied my d3 code to a simple javascript file, with only the latest d3 scripts, and it works. Any insight would be appreciated. Thanks so much in advance.
