QUESTION
I am plagued by a very strange phenomenon. I tend to write fairly esoteric Powershell modules for stuff I do at work. Often, after running one of these, and the module has ended I will move onto some other tasks, and when I happen to bring up my Powershell console window again, several blank lines (or just blank "space") will have appeared in the buffer. It never appears right away, which is the most confounding part.
Afterwards, the blinking cursor exists at the end of this blank space, and the blank space cannot be "backspaced" (so it's not something inadvertently entering spaces or newlines). It's just there, as part of the buffer. I usually just clear the screen with cls
to keep it from annoying me.
I used to just chalk this up to the buggy Windows Powershell 5.1 buffering. However now that I've begun using Powershell 7 (and Windows Terminal), I see that the issue still exists.
Here is a screenshot of a v7 Windows Terminal tab an hour or so after my module finished running:
Sometimes it seems the longer I wait the more blank space has appeared. Here is a screenshot of the same console tab about 20 hours later:
I'm sorry I don't have a better way of explaining this. I realize that without any code or pattern to analyze, that this is a very poor question, by SO standards, but I am just as confused as you are. The only pattern I've noticed is that this only seems to happen after I run my various custom modules. However this accounts for the majority of my Powershell usage, so it might be a red herring.
Usually my modules simply do some processing (talking to computers, AD, etc) and just output some information via Write-Host
, and occasionally output a [PSCustomObject]
, which I always capture in a variable. Even if I was accidentally outputting some blank lines or something to the pipeline, I can't see how that would manifest as blank buffer space that grows over time. I thought maybe I was incorrectly killing async jobs or something and that was somehow causing this, but this happens even in purely synchronous code.
To be clear, in the screenshots above there is no code actually running. That module was the only thing I had run in this particular console tab/session, and it doesn't run any background processes. So I can't understand why the buffer is changing all on its own. In both screenshots, the tab/window is the same size as it was when the module first completed, so it's not just a bunch of spaces in the buffer that are being dynamically resized. And as noted, when the module fist completed there were NO rogue characters in the buffer at all.
One other thing about my usage is that it's all done on a remote VM, accessed through RDP, which I use daily. The only other thing I can think of is that maybe something about the console window being minimized/maximized/resized, the resolution changing, or the login session being connected/reconnected has something to do with it.
Does this sound familiar to anyone? Any ideas for what could be causing this or what I can try to understand the behavior better are much appreciated.
...ANSWER
Answered 2021-Jun-03 at 15:38I've confirmed that this actually happens as a direct result of simply "restoring" and "maximizing" the Powershell console window and/or Windows Terminal window. When the issue is "present", doing this will often add another "set" of blank space to the buffer before the cursor. Minimizing seems to have no effect, only going from maximized to "restored" and back to maximized.
I've also confirmed that this has nothing to do with my custom modules. I can replicate the issue by simply opening a fresh, maximized console window/tab, running get-process
and then "restoring" and maximizing. It doesn't happen every time though.
It also has nothing to do with my custom profile script, as it happens even on a freshly-imaged computer with no profile.
At this point I'm going back to blaming it on buffer/rendering/window manager implementation bugs in powershell and moving on with my life.

QUESTION
I have two ejs forms that when hit, make an HTTP post request to my /api/users/makePicks/:id route. This route hits my controller which updates the Users model in my mongodb with the NFL picks they submitted in the EJS form.
I need this route to create the picks object for each route if they do not exist for that particular week, and if they do exist it needs to update the picks that are already there. The picks are being stored in my User model in an array, this array contains objects for each weeks picks. Currently the code, with much help from Mohammed, is successfully pushing code to to array. But i cannot seem to figure out how to update the picks if an object with a key of that week exists.
My validation is finally working properly. What I mean is we are running a for loop on the picks array, it will console.log true if there is already a matching picks object with for that weeks picks, if the object with a first key value with the current weeks form doesn't exist, it will console.log false and push the new picks to the array.
The only part that isn't working is the if statement nested within my for loop, it is not updating the object if it already exists in the picks.array. But as I said, the validation is working correctly. I suspect the line of code

Answered 2021-May-21 at 17:17Unfortunately, you basically have to draw the outline manually with a bunch of points, just the way you've done so far (there are ways to do it automatically, but the only ones I know of require some pretty advanced techniques). Here's some code that might help you figure out where to draw the points:

I have an express server in a node app. I need to be able to run this node app with the debugger. I also need to be able to stop and restart the server easily without binding up the port it runs on. I need to tap into the shutdown to do some cleanup, which I do like this:

Answered 2021-May-18 at 18:25To get the debugger to disconnect, you need to close the Chrome tab that has the debugger connection in it. That will allow the previous instance of your app to fully exit.

QUESTION
my Problem is fairly simple: I got 3 Methods:
export function F_SetupDatabase(_logger: any): void
export function Q_RunQuery(query: string, db: "session" | "global"): any
export function Q_RunQueryWithParams(query: string, params: string[], db: "session" | "global"): any
To Access a Database File (SQLite3).
( Call order: F_SetupDatabase(..)
-> Q_RunQuery(...)
)
F_SetupDatabase(...)
is used to open a Database File global-database.db
and create another in-Memory Database session
. My main Problem is, that in my App's Main Function, the logs from Q_RunQuery
show up before F_SetupDatabase
. And Query's also won't work and always return undefined
. So i guess it has something to do with async/sync calls or something like that.
I tried to avoid async calls/methods completley 'cause i lack the experience and always hang up myself with these.
SQL Querys are correct.

ANSWER
Answered 2021-May-11 at 08:56Well, I think it may happen because of the Async code. Each query runs async, so you can not access the result of a query, you need to wait for its execution.

Answered 2021-May-09 at 11:51You should try use SSL certificate on your front-end/back-end to ensure that data transferred is not visible explicitly, is private and integral link here.
Maybe you should wonder about something like Basic Authentication. It's additional information in HTTP Header with credentials. Check this out.
Never store passwords as plain text. Use something like BCrypt with random salt added. Try this.

Answered 2021-Apr-28 at 12:55This may be a silly answer. Try checking whether the task is running or any other programs interfereing the app, like an antivirus.
