QUESTION

An idiomatic way to stop / kill / cleanup useless producer go routines

Asked 2022-Apr-11 at 06:10

I am learning Go and read some articles about goroutines and channels. This seems like a really nice feature of Go. But... I don't understand a good/idiomatic way to ensure proper cleanup for what I would call a 'useless producer goroutine'.

There's an article that explains the problem quite well, and it inspired this question. While the article explains the problem well, I find the solutions it's offering not very compelling because they lack a bit in generality (e.g. the 'just use buffered channels' doesn't really work for an infinite producer).

Note: You may read the article for background/reference, but I'll explain enough here to make my question self contained.

What do I mean with a 'useless producer'? I mean two things:

a producer is a goroutine who's only purpose is to do some processing and send some values to a channel. A producer may produce any number of values, including potentially infinitely many (e.g. say a producer that produces all prime numbers).
a useless producer means a producer that is sending values to a channel that is no longer accessible to anyone but itself.

Let me clarify with a concrete example. Below is an example of function that creates a 'Prime number producer' and returns a channel that allows a consumer to get any number of primes.

ANSWER

Answered 2022-Apr-10 at 18:42

The idiomatic way of doing this is notifying the generator goroutine using another channel, or a context, that its results are no longer needed.

ShouldProcess failing in PowerShell7

Asked 2022-Mar-11 at 18:59

Environment: Windows Server 2022 21H2, Powershell 7.2 (running as administrator)

I have a script that implements ShouldProcess, which works fine in Windows PowerShell 5. However, in PowerShell 7, the script invariably throws the error Cannot find an overload for "ShouldProcess" and the argument count: "1". ShouldProcess at MSDoc says that the one-argument overload for $PSCmdlet.ShouldProcess() exists and should work.

It's failing, as above. Why?

For reference, this error can be reproduced on both PowerShell versions 5.1 and Core. The steps to reproduce is passing a System.Management.Automation.PSObject as argument to the .ShouldProcess(String) overload. It makes sense, by looking at your comment mentioning a serialized object. In below example, if the System.Diagnostics.Process object is not serialized it works properly on both versions.

As covered in the comments, it looks like you're not pulling anything from your database. It's not clear what your query is (presumably pull all), but maybe check that your connection string is actually pointing at the instance you think it is. Presumably it's connecting to something since it's not throwing, but it might be some local dummy instance.

Some other thoughts since you indicated you're learning this from a tutorial:

When you pull data from your database, add some sanity checks lest you have the same issue with your statuses.
Assuming your BasicUserModel assigns an id upon creation, you probably only want to do this once. Instead of creating a separate author for each entry, do this once at the top once you've pulled the foundUser and pass that variable into each each Author property.
By my count, you make at least 17 calls to your database across your page. Look for a bulk insert statement and pass an list of your new values into it to minimize load and latency.
For one, I would advise you use TryGetValue on your _cache value since you can instead put something like:

QUESTION

What Should I Do To View The Formatted Data In WYSIWYG Editor?

Asked 2022-Feb-10 at 06:29

I'm developing a web application using ASP.NET MVC. I want to submit the formatted text held in the MsSQL database to Summernote for editing. However, the JavaScript method I developed on the client side does not add only the post content from the server to the HTML document. I looked through the Insertion API in the Summernote documentation but couldn't find a solution.

The debug image below shows PostContent data coming from the database. The parts of the program I have developed are available below. What do I need to do to fix this problem?

You are probably using an updated version of Summernote. To print the formatted data from the database to the summernote container, update the $("#summernote").code(e.PostContent); line as follows:

Load/stress test in a SPA with Hasura Cloud Graphql as a backend and subscriptions

Asked 2022-Jan-26 at 07:32

I'm trying to do a performance test on a

SPA with a Frontend in React, deployed with Netlify
As a backend we're using Hasura Cloud Graphql (std version) https://hasura.io/, where everything from the client goes directly through Hasura to the DB.
DB is in Postgress housed in Heroku (Std 0 tier).
We're hoping to be able to have around 800 users simultaneous.

The problem is that i'm loss about how to do it or if i'm doing it correctly, seeing how most of our stuff are "subscriptions/mutations" that I had to transform into queries. I tried doing those test with k6 and Jmeter but i'm not sure if i'm doing them properly.

k6 test

At first, i did a quick search and collected around 10 subscriptions that are commonly used. Then i tried to create a performance test with k6 https://k6.io/docs/using-k6/http-requests/ but i wasn't able to create a working subscription test so i just transform each subscription into a query and perform a http.post with this setup:

Answered 2022-Jan-26 at 00:14

I'm not sure if i'm doing it correctly, if transforming every subscription into a query and perform a http request is a correct approach for it. (At least I know that those queries return the data correctly).

Ideally you would be using WebSocket as that is what actual clients will most likely be using.

Connection Leak in Azure WebApp Using Python on Ubuntu

Asked 2022-Jan-24 at 17:24

I have a Flask App running on an Ubuntu WebApp on Azure. Every morning my queries to the app fail with the below error:

sqlalchemy.exc.OperationalError: (pyodbc.OperationalError) ('08S01', '[08S01] [Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: Error code 0x68 (104) (SQLExecDirectW)')

I am using SQLAlchemy ORM to query my Azure SQL Server Instance. I believe that my connections are becoming stale for the following reasons.

It happens every morning after no one uses the app
After X many failed returns, it starts working, until the next morning.

However to make things more weird, when I check sys.dm_exec_sessions on the sql server, it does not show any active connections (outside of the one I'm executing to check).

In addition, when I run the dockerized app on my local and connect to the DB I get no such error.

If anyone has had a similar issue I'd love some insights, or at least a recommendation on where to drill down.

Avalonia ReactiveUI RoutedViewHost not creating embedding appropriate view

I was following this tutorial, which I do see is based on the .net core 2.1 framework, but adapted for the .net 5 avalonia.mvvm template. I followed the code line for line with the exception of the Program.cs file given the fact that the avalonia.mvvm template in .net 5 implements the ViewLocator.cs class so I don't believe I have to use Locator. Yet, when I run the app while the Router.NavigationStack.Count increments, the view remains on its default content. Here is the code

How to calculate Deposit Amounts for Adding Liquidity within Uniswap V3

Asked 2021-Jul-27 at 13:04

Whilst adding liquidity to a new pool within Uniswap V3, I am trying to calculate the formula for the 'Deposit Amounts' on any given pair.

For example, lets take the pair ETH/USDC

Current Price: 2172.05 Set price Rangle -20% & +20%

Min Price: 1747.7 Max Price: 2612.4

ETH: 0.394064 ($854.888) USDC: 1000 ($1000)

How is the ETH dollar amount calculated and what is the formula? (How did Uniswap get ETH to $854.888 ???)

ps: I have looked at the Uniswap V3 white paper https://uniswap.org/whitepaper-v3.pdf but need a step by step layman explanation. Cheers!

ANSWER

Answered 2021-Jul-25 at 15:50

This question might be a bit off-topic for SO, but I believe it will be useful for people anyway. Here is my answer...

Uniswap gave you the USD value of ETH amount you entered, just for convenience, using an oracle price. It's not a parameter of this deposit operation.

There are only 3 parameters here:

Asset A amount
Asset B amount
Price range

Asset A (ETH in your instance) ratio to Asset B (USDC in your instance) determines the equilibrium point. For example, if you deposit 1 Ether and 1000 USDC, then the equilibrium point will be ETH = 1000 USDC. Lastly, you define a price range to specify the range you want your deposit to be functional. By limiting the price range of your deposit, you increase the efficiency of the capital (deposit) in a given range. This involves quite a bit of math to explain but let me try to explain in a nutshell: Basically, automated market makers work on this equation: a * b = k. This implies when a goes to infinity b goes to zero and vice-versa. Because of this 'liquidity' is distributed over 0 to infinity, uniformly. When you put price ranges instead, you 'concentrate' liquidity inside the range, at expense of outside-range liquidity. Thus you increase the efficiency of capital.

pg_wal folder on standby node not removing files (postgresql-11)

ANSWER

Answered 2021-Jun-14 at 15:00

You 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.
