How do you turn on flags for a capturing subgroup using re2 regular expressions with BigQuery |
|regex|google-bigquery|re2| |
Use a nested capturing group within the non-capturing group like this
`(?is:(My name is ))(\w+)`
`REGEXP_REPLACE(str, r'(?is:(My name is ))(\w+). ', r'\1 C')` |
That is a **very** bad idea. A randomized delay would change the ordering of the packets passed between the layers. That is definitely something that does not happen in real life systems. A fixed, non-random delay may or may not be ok.
INET supports modeling processing delay in Switches where it models the processing time requires to do the work to decide where to forward the packet. But still, the delay must be constant. |
I am creating a report for Business Central and unfortunately this change can't be made within AL so I'm having to try an expression change for the field in RDLC.
The field is currently, =Fields!HighDescription.Value
I need to get rid of leading values if the value pulled in begins with: RS-BE
Here is what I have tried with no success yet:
=IIf(Left(Fields!HighDescription.Value, 6) = "RS-BE", Mid(Fields!HighDescription.Value, 6), Fields!HighDescription.Value)
=Switch(Left(Fields!HighDescription.Value, 6) = "RS-BE", Mid(Fields!HighDescription.Value, 6), True, Fields!HighDescription.Value)
=IIf(Left(Trim(Fields!HighDescription.Value), 6) = "RS-BE", Trim(Mid(Fields!HighDescription.Value, 6)), Trim(Fields!HighDescription.Value))
These expressions did not change anything and brought in the values as normal. |

How would I write *n* nested *for* loops without knowing what *n* is?
For example, how would I write the following using recursion or another method?
for (int i = 0; cond1; i++) {
for (int j = 0; cond2; j++) {
for (int k = 0; cond3; k++)
...
for (int l = 0; cond_N; l++) {
if (.....) break;
}
}
}
}
Here, there are *n* loops with some condition (not necessarily the same condition for each variable) and I'm not sure how to transform this into code using recursion without knowing what *n* is.

Is there a way to make this request with UrlFetchApp in app script?
`curl -X GET http://test.com/api/demo -H 'Content-Type: application/json' -d '{"data": ["words"]}'`

```
const response = UrlFetchApp.fetch(API_URL, {

I have seen a few other questions here but none of them really achieve what I want them to. I guess I'm open to using Javascript or jQuery here, whatever works best.
Question:
I have a page with a link that redirects the user to a FAQ page, if this link is clicked, I want the user to be redirected to the new page AND to scroll down to a specific element(one of the drop-down questions), and open it (simulate a click). Is this possible?
Here is the link from the initial page:
```https://somethinghere.com#q5-section```
As you can see I have already added the anchor tag at the end, doesn't seem to be working (does it matter if link is opened in a new tab or same window? Currently it opens a new tab
And the ID of the drop-down that should be opened on the new page when that link is clicked is ```#q5-section```
Here is the HTML code from the entire FAQ drop-down:
```HTML
<div class="faq-question" id="q5-section">
<input id="q5" type="checkbox" class="panel">
<div class="plus">+</div>
<label for="q5" class="panel-title">................</label>

</ul>

```
If there is any missing info to achieve this please let me know. |

You would create a base `projen` configuration, then make it available for target projects, e.g. as a package published to a shared NPM registry.
When you make changes to the base configuration, you would go to the target repositories, update the package, make any necessary updates, e.g. for breaking changes, re-apply the changes and push a pull request.
In a sense, it's not much of a different workflow as you're already accustomed with for, say, having a shared ESLint configuration package. |

I wanted to add a modern, functional-style recursive function based on @AndrewMoore's script.
None of the logic has changed. Iterate over all keys of a level. If the value is an array, traverse into the array. Prepend the carried prefix to each encountered key.

array_map(
fn($k, $v) => is_array($v) ? getKeyPaths($v, "$prefix$k") : "$prefix$k",

I'm buiding a React component that changes state on button click *AND* after some timed interval, after button click, changes back to its original state.
Here is my simple code:
import React, { useState, useEffect } from "react";
const TimedButton = (props) => {
const [user_id, setUserId] = useState("FIRST");
const handleClick = (event) => {
setUserId("SECOND");
setTimeout(() => {
console.log("Trigger...");
console.log(user_id)
if (user_id) this.setUserId("FIRST");
}, 1000);
};
return (
<div>
<button onClick={handleClick}>
{user_id}
</button>
</div>
);
};
export default TimedButton;
On click, `FIRST` changes to `SECOND`, fine. After timeout (1 second), `user_id` is set back to `FIRST`, but for some reason it's not re-rendering the screen, that remains as `SECOND` (but at that point user_id is `FIRST`).
Help appreciated to solve this.

I have a simple question.
I'm using "**app folder**" in my Next js 14 project.
In the **layout.tsx** file (**can also be page.tsx**) I get data from the server side API and pass it to the child components using props. This gets annoying when there are many nested children components. In addition, I also need to type the data that I pass using props.
Yes, I know, if I make the same request on the server components, Next js does not send a new request, it pulls it from the cache. However, I can't do this because **my children components are on the client side**. How do you cope in such situations?
Thank you in advance.

I've added the ```printf()``` statements in ```binToDec()``` for debugging, and it seems that the compiler is ignoring the ```return dec_eqv;``` statement in the final ```else``` block and directly executing the ```return -1;``` at the end.

I have tried to isolate my problem in a very simple (and working) project. Let's say I have a simple model with 2 fields, and I have configured its properties and a `PropertyChanged` event. This is a simplified implementation of my model, please notice the last method just gets a new client object from a list and returns it:
public class Clients : INotifyPropertyChanged
{
private long _Id = 0;
public long Id
{
get { return this._Id; }
set {
this._Id = value;
RaisePropertyChanged("Id");
}
}
private String _Name = string.Empty;
public String Name
{
get { return this._Name; }
set {
if (value is null)
this._Name = string.Empty;
else
this._Name = value;
RaisePropertyChanged("Name");
}
}
public event PropertyChangedEventHandler? PropertyChanged;
internal void RaisePropertyChanged(string name)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(name));
}
// Let's say this is a populated list with 100 clients with different ids and names
public static List<Clients> clients = new List<Clients>();
// ...method for loading the list with DB data
public static Clients? LoadClient(long id)
{
return clients.FirstOrDefault(x => x.Id == id);
}
}
And I have a simple `.xaml` file in order to display one client data (id and name). Each UI control has a binding with the client property and the trigger for updating. I have also 2 configured buttons that will make changes to the client values:
<TextBox x:Name="txtClientId" Text="{Binding Id, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
</TextBox>
<TextBox x:Name="txtClientName" Text="{Binding Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}">
</TextBox>
<Button Name="btnNext" Click="btnNext_Click">Next</Button>
<Button Name="btnRandom" Click="btnRandom_Click">Random</Button>
Now let's take a look to my `.xaml.cs` code. Here is the initializing and the code for the 2 buttons: one of them just modify the client properties in the `DataContext` object directly, and the other just assigns a new client object to the `DataContext` client:
public partial class ClientsPage : Page
{
private Models.Clients? client = null;
public ClientsPage()
{
InitializeComponent();
// Load all clients data in Models.Clients.clients list...
client = new Models.Clients();
DataContext = client;
}
private void btnNext_Click(object sender, RoutedEventArgs e)
{
client = Models.Clients.LoadClient(client.Id + 1);
}
private void btnRandom_Click(object sender, RoutedEventArgs e)
{
Random random = new Random();
client.Id = random.Next(999);
client.Name = "RANDOM";
}
}
- When I set the DataContext, data is displayed correctly in the UI -> OK
- When I make changes directly in the properties of the client object changes are reflected correctly in the UI -> OK
- But... when I load a new client object, and assign it to the variable set as `DataContext`, the `PropertyChanged` event is not raised.
Of course this situation can be solved by assigning property values instead of assigning a new object directly:
private void btnNext_Click(object sender, RoutedEventArgs e)
{
Models.Clients newClient = Models.Clients.LoadClient(client.Id + 1);
this.client.Id = newClient.Id;
this.client.Name = newClient.Name;
}
But it is so tedious in a real project with many models and methods that can load/modify an object with a lot of fields. I'm looking for an easy/scalable way for making the `PropertyChanged` event fire when I assign a new object to the `DataContext` variable. If you need more detail of my code or have any question I'll be happy to ask. |

Architecture: Flask app running in its own container, Celery running in its own container. Message broker is Redis. This is all python btw.
Problem: I cant figure out how to register a class based task with a custom name.
Versions:
```
celery==5.2.7
redis==5.0.3
```
Details: I want to build class based tasks as I want to be able to use the `on_success` handler on every task. Note all class based tasks are defined in the celery container, so the flask app has no way to know what they are. The flask app must be able to call them by a "name". I tried using the default name, which I could not get to work with celery based classes, it required a name. I also tried to configure a custom name. Every time I try to do this I get this error

Really I just want to find a way to have celery tasks perform an operation after they complete their tasks. `on_success` seems like the right thing to do, but I cant figure out how to use it outside of a class based task, and I cant get class based tasks working. Can anyone help? |

Here is one solution assuming that your structure is only 3 levels deep
``` lang-txt
variable "input_list" {
default = {
"a" = {
"a1" = {}
"a2" = {}
}
"b" = {
"b1" = {}
"b2" = {
"b21" = {}
}
}
}
}
locals {
paths = flatten([
for k0 in keys(var.input_list) : [
for k1 in keys(var.input_list[k0]) : [
length(keys(var.input_list[k0][k1])) > 0
? [for k2 in keys(var.input_list[k0][k1]) : "${k0}/${k1}/${k2}"]
: ["${k0}/${k1}"]
]
]
])
}
output "paths" {
value = local.paths
}
```
when we do a terraform plan on that we will get:
``` lang-txt
terraform plan
Changes to Outputs:
+ paths = [
+ "a/a1",
+ "a/a2",
+ "b/b1",
+ "b/b2/b21",
]
```
That should give you an idea what to do **IF** your structure has a max amount of levels, you can use this same technique to extract what you need, just add more nested loops to match your max.
If you do not know the amount of levels, you will need a recursive way to navigate the directory and I honestly don't think that is possible with the builtin functions from Terraform, you might need to extract that with some other tool/script then pass it as an input parameter. |
What are you trying to do is called _pivoting_, so use [`DataFrame.pivot()`][1]:
```py
import pandas as pd
df = pd.read_csv("your_file.csv", header=None)
out = (
df.pivot(index=1, columns=0, values=2)
.rename_axis(index="ID", columns=None)
.reset_index()
)
print(out)
```
Prints:
```none
ID 1:100011159-T-G 1:10002775-GA 1:100122796-C-T 1:100152282-CAAA-T
0 CDD3-597 GG GG TT CC
1 CDD3-598 GG NaN NaN CC
```
---
EDIT: With your updated input:
```py
import pandas as pd
df = pd.read_csv("your_file.csv", header=None)
df["tmp"] = df[[2, 3]].agg("".join, axis=1) # <-- join the two columns together
out = (
df.pivot(index=1, columns=0, values="tmp")
.rename_axis(index="ID", columns=None)
.reset_index()
)
print(out)
```

Given an linear system Ax=b, x = [x1; x2], where A,b are given and x1 is also given. A is symmetric. I want to compute the gradient of x1 in terms of A,b, i.e. dx1/dA, dx1/db. It seems that torch.autograd.backward() can only compute the gradient by solving the whole linear system. But I want to make it more efficient by not solving x1 again since it is already given. Is it feasible? If so, how to implement it using pytorch?
For now, I only know how to get the gradient by solving the whole system:
```
#[A1 A2; A3 A4] * [x1; x2] = [b1; b2]
m1 = 10
n1 = 10
m3 = 5
n3 = n1
m2 = m1
n2 = m1 + m3 - n1
m4 = m3
n4 = n2
A = torch.rand((m1+m3,n1+n2)).clone().detach().requires_grad_(True)
A1 = A[:m1,:n1]
A2 = A[:m1,n1:]
A3 = A[m1:,:n1]
A4 = A[m1:,n1:]
# x1 is already given
x1 = torch.ones((n1,1)).clone().detach().requires_grad_(True)
# x2 needs to be solved
x2_gt = torch.rand((n2,1))
b1 = (A1 @ x1 + A2 @ x2_gt).detach().requires_grad_(True)
b2 = (A3 @ x1 + A4 @ x2_gt).detach().requires_grad_(True)
b = torch.vstack((b1,b2))
x = torch.linalg.solve(A,b)
x.backward(torch.ones(m1+m3,1))

I have a problem where my table users have:
@OneToMany(mappedBy = "id.utenti", cascade = {CascadeType.ALL}, orphanRemoval = true)
private List<UtentiCatenaRuoli> ruoliUtente = new ArrayList<>();
that is linked to a relation table with 3 foreign keys, user, role and section where role apply.
Using mapstruct i map DTO to Entity and vice-versa, for example creating an user works like that:
{
"nome": "test",
"ruoli": [ # Translate for roles
{
"1": "ANAGRAF" # Pair for section and role
},
{
"1": "ASSEGNA"
}
]
}
That works on create, no problems. The same code dosn't work when I try to update.
I get the EntityByReference, pass it to mapstruct update method, use the same "qualifiedByName" used in create but hibernate dosn't fill the "user" field on relation.
I'll try to explain more:
@Named("toUtenteRuoloCatenaList")
default List<UtentiCatenaRuoli> toUtenteRuoloCatenaList(List<Map.Entry<Long, String>> values,
@Context RuoliRepository ruoliRepository,
@Context CatenaComandoRepository catenaComandoRepository) {
List<UtentiCatenaRuoli> utentiCatenaRuolis = new ArrayList<>();
values.forEach(pair -> {
UtentiCatenaRuoliPK utentiCatenaRuoliPK = new UtentiCatenaRuoliPK(catenaComandoRepository.getReferenceById(pair.getKey()), ruoliRepository.getReferenceById(pair.getValue()));
UtentiCatenaRuoli utentiCatenaRuoli = new UtentiCatenaRuoli(utentiCatenaRuoliPK);
utentiCatenaRuolis.add(utentiCatenaRuoli);
});
return utentiCatenaRuolis;
}
This is what my mapstruct function uses for conversion from DTO roles to Entity, utentiCatenaRuoliPK is missing the user reference id that hibernate fills alone on INSERT, same thing dosn't happend on UPDATE.
Result:
Update throw exception cause relation table user filed can't be null.
Why there is a different treatment for insert and update?
EDIT:
I'm using something similiar with a relation table that have only 2 foreign keys and all works fine(user_ref get autofilled in both situations) |
Entity relation isn't updated when referencing more than one field |

I am trying to create a custom widget for DropDownButton. It seems to work fine. The onChanged() func is also working when I take console print of the changed value.

You're using a string as `src` instead of the actual import. Use the imports as the `src`.

I have a pretty simple queue which happens to have heaps of messages on it (by design). Heaps can be "thousands" here.
Right now I'm playing around with using Azure Web Jobs with a Queue Trigger to process the messages. Works fine.
I'm worried about performance though. Let's assume my method that processes the message takes 1 sec. With so many messages, this all adds up.
I know I can manually POP a number of messages at the same time, then parallel process them .. but I'm not sure how we do this with web jobs?
I'm _assuming_ the solution is to scale _out_? which means I would create 25 instances of the webjob? Or is there a better way where I can trigger on a message but pop 25 or so messages at once, then parallel them myself.
NOTE: Most of the delay is I/O (ie. a REST call to a 3rd party). not CPU.
I'm thinking -> create 25 tasks and `await Task.WhenAll(tasks);` to process all the data that I get back.
So, what are my options?
NOTE #2: If the solution is scale out .. then I also need to make sure that my web job project only has _one_ function in it, right? otherwise _all_ the functions (read: triggers, etc) will also _all_ be scaled out.

I want to try to declare an abstract class field in a Python base class.
I know that python can declare an abstract object field via `@property` and `@abstractmethod`, but I haven't checked for a viable abstract class field.
I want to be able to implement such use case:
```python
class AbcClass(metaclass=ABCMeta):
@abstractproperty
class_field: int # class-level static field
# inherite abstract class
class MyClass(AbcClass):
class_field = 42
```
About related thread:
[Python: Create Abstract Static Property within Class](https://stackoverflow.com/questions/49022656/python-create-abstract-static-property-within-class): This post does give some viable options, but since I'm trying metaprogramming, using `__init_subclass__` causes IDE support to become difficult. |

I'm writing a Tkinter program that so far creates a window with a menu bar, a File menu, and a single item. The menu is successfully created, but with two items, the first being one that I did not specify, whose name is "-----".
If I don't add an item, the spontaneous one is still added. This still happens if I specify tearoff=0.
Any idea why this is happening?
Windows 11, Python 3.12.2, Tkinter and Tcl 8.6.

There are two types of errors can be occured in our server. So try catch block can handle Synchronous errors.
try {
my_function();
}
catch(e){
};
But for asynchronous errors
try {
my_function();
}
catch(e){
next(e);
};
also you chan use .then() instead of try catch
Promise.resolve().then(() => {
throw new Error('BROKEN')
}).catch(next)
documentation - [Express error handling][1]
you can use express-async-handler for handle this very easy [express-async-handler][2]

Use
SELECT `Order ID` FROM Returnedsss;
or
SELECT [Order ID] FROM Returnedsss;
or
SELECT "Order ID" FROM Returnedsss;
The issue is how single quotes are used to enclose a literal value character string in preference to enclosing a component name (column table etc).

I was getting the same error. I tried a lot of fixes from the internet but nothing worked but thanks to our teacher, with his help i was able to fix it. so the error i was getting said that

notice the line `lrwxrwxrwx 1 root root 10 Feb 12 19:50 python3 -> python3.10`
I realized that my python was pointing python3.10 even though i had python3.11 installed. so it should be pointing to python3.11 instead.
If that's the same case with you then you've figured out the problem and the **following fix should work just fine for you.**
1. **Locate Python 3.11:** First, ensure that Python 3.11 is installed on your system. You mentioned it's installed, so you can proceed to locate its path. You can usually find it in `/usr/bin/` or `/usr/local/bin/`. Let's assume it's in `/usr/bin/python3.11`.
2. **Update the Symbolic Link:** You need to update the python3 symbolic link to point to Python 3.11. You can do this using the ln command in the terminal. Open a terminal and type:<br>
`sudo ln -sf /usr/bin/python3.11 /usr/bin/python3`
3. **Verify the Update:** After running the command, you can verify that the symbolic link has been updated correctly by typing: <br>
`ls -l /usr/bin/python3` <br>
<br>
This should show something like:<br>
`lrwxrwxrwx 1 root root XX XXX XX:XX /usr/bin/python3 -> /usr/bin/python3.11`
<br><br>This indicates that python3 now points to Python 3.11.
Now, when you run your PySpark code, it should use Python 3.11 on both the worker nodes and the driver, resolving the version mismatch issue. |
Let's consider your statement `let mut last = *self.tail;`. As The Rust Reference documents under [`let` statements](https://doc.rust-lang.org/reference/statements.html#let-statements):
> A *`let` statement* introduces a new set of [variables](https://doc.rust-lang.org/reference/variables.html), given by a [pattern](https://doc.rust-lang.org/reference/patterns.html).
Your pattern, `mut last`, matches the grammar of an [Identifier pattern](https://doc.rust-lang.org/reference/patterns.html#identifier-patterns), about which The Rust Reference documents:
> By default, identifier patterns bind a variable to a copy of or move from the matched value depending on whether the matched value implements [`Copy`](https://doc.rust-lang.org/reference/special-types-and-traits.html#copy). This can be changed to bind to a reference by using the `ref` keyword, or to a mutable reference using `ref mut`.
In your case, the matched value `*self.tail` is of type `Node` which does indeed implement `Copy`, so a variable represented by the `last` identifier is bound to a *copy* of that `Node`. You then mutate that copy, after which it is dropped when `last` goes out of scope; the memory in `*self.tail` is left unchanged.
To bind by reference instead, which will accomplish what you had intended, you can explicitly use a `ref mut` binding as mentioned in the quote above:
```rust
let ref mut last = *self.tail;
```
However, The Rust Reference goes on to document under [Binding modes](https://doc.rust-lang.org/reference/patterns.html#binding-modes):
> To service better ergonomics, patterns operate in different *binding modes* in order to make it easier to bind references to values. When a reference value is matched by a non-reference pattern, it will be automatically treated as a `ref` or `ref mut` binding.
Thus you can alternatively still use a non-reference pattern by matching against a reference to `*self.tail`:
```rust
let last = &mut *self.tail;
```
In both cases, what's happening is somewhat more obvious if you consider the type of `last`: in your original attempt, `last` was of type `Node` whereas in both of the above it is of type `&mut Node`.
---
That all said, it probably isn't necessary to use raw pointers and `unsafe` code here at all (and I would ***strongly*** encourage you not do so). For example, you could do something along the following lines:
```rust
use std::{cell::{Cell, RefCell}, rc::Rc};
struct IntList {
head: Option<Rc<Node>>,
tail: Option<Rc<Node>>,
size: usize,
}
#[derive(Clone)]
struct Node {
data: Cell<i32>,
prev: RefCell<Option<Rc<Node>>>,
next: RefCell<Option<Rc<Node>>>,
}
impl IntList {
fn new() -> Self {
IntList {
head: None,
tail: None,
size: 0,
}
}
fn add_last(&mut self, v: i32) {
let prev = RefCell::new(self.tail.take());
let next = RefCell::new(None);
let node = self.tail.insert(Rc::new(Node { data: Cell::new(v), prev, next }));
if self.size == 0 {
self.head = Some(Rc::clone(node));
}
self.size += 1;
println!("added:{node}");
}
}
```
Admittedly, this does add the fairly trivial costs of storing and updating reference counts and runtime borrow-checks which a raw-pointer based version need not. However, even if you want to avoid that, why reinvent the wheel when the standard library gives you [`std::collections::LinkedList`](https://doc.rust-lang.org/std/collections/struct.LinkedList.html) ("*A doubly-linked list with owned nodes*")? In any case though, note what it says:
> NOTE: It is almost always better to use [`Vec`](https://doc.rust-lang.org/std/vec/struct.Vec.html) or [`VecDeque`](https://doc.rust-lang.org/std/collections/struct.VecDeque.html) because array-based containers are generally faster, more memory efficient, and make better use of CPU cache. |
In the past, I placed the following code snippet in function.php to speed up the checkout process in WooCommerce:
add_filter( 'woocommerce_defer_transactional_emails', '__return_true' );
However, recently I have not been receiving emails when there are new orders. After removing the above code snippet, everything works fine, but it slows down the checkout process by 20-30 seconds. Upon investigation, I found the error here:
Uncaught Error: Call to a member function format() on null in /woocommerce/emails/email-order-details.php:34
$order->get_date_created()->format( 'c' )
Is there a way to delay email processing to speed up the checkout process without causing this error? Or how can I fix the error mentioned above? |

The algo is the following:
1. Calculate total size of all items
2. Get size of a group
3. Iterate items and push to groups according to the current sum of item sizes
It doesn't include a case when there's both groups share equal amount of an item.

I saw this [thread](https://www.reddit.com/r/unrealengine/comments/gpc2hh/ghost_trail_motion_trail_removal/) where they describe an issue that I've been having where the machine struggles with calculating AA so it leaves a ghost trail.
I want to record the viewport and use these as videos so no real time calculations are needed.
Would this be solved by rendering/baking?
I did a quick render test but the issue was still there but maybe I missed something.
Before I go that route I wanted to know if it's possible.
Thank you for your help. |

I was trying to generate a presigned URL for an S3 bucket in the `me-central-1` region using the boto3 library, as demonstrated below
```
client = boto3.client("s3", region_name="me-central-1")
return client.generate_presigned_url(
ClientMethod="put_object",
Params={"Bucket": bucket, "Key": path},
)
```
This generates a url with the following form: `https://bucket.s3.amazonaws.com/path?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential={CREDENTIAL}/{DATE}/me-central-1/s3/aws4_request&X-Amz-Date={DATETIME}&X-Amz-Expires=1800&X-Amz-SignedHeaders=host&X-Amz-Signature={SIGNATURE}`
However, trying to use this url results in an `IllegalLocationConstraintException` with the following message: `The me-central-1 location constraint is incompatible for the region specific endpoint this request was sent to.`
I did a bit of research into why this was happening and found that S3 endpoints going to regions other than us-east-1 needed to include the region like so: `https://bucket.s3.REGION.amazonaws.com/...`.
I then changed the boto3 client instantation to the version below:
```
client = boto3.client("s3", region_name="me-central-1", endpoint_url="https://s3.me-central-1.amazonaws.com")
```
The resulting url had the form: `https://s3.me-central-1.amazonaws.com/bucket/path?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential={CREDENTIAL}/{DATE}/me-central-1/s3/aws4_request&X-Amz-Date={DATETIME}&X-Amz-Expires=1800&X-Amz-SignedHeaders=host&X-Amz-Signature={SIGNATURE}`
This URL seems to work without returning an `IllegalLocationConstraintException`! However, I noticed this was now a path-style request instead of a virtual-hosted-style request (as defined [here](https://docs.aws.amazon.com/AmazonS3/latest/userguide/VirtualHosting.html)). The provided webpage also states path-style requests will be discontinued, so I will not be able to use the above code for a long-term solution.
My attempts to manually change the path-style request into a virtual-hosted-style request resulted in a `SignatureDoesNotMatch` error, with the message: `The request signature we calculated does not match the signature you provided. Check your key and signing method`.
My question would be - is there a way to make the boto3 client return a valid virtual-hosted-style presigned url? |

Our production pipeline builds fine under Ubuntu 20.x. I don't have access to a 23.x system, but have you tried only installing and running only `hugo` from `hugo-extended` like this:
```console
$ npx -p hugo-extended \hugo version
```
If that fails then the problem is with the [hugo-extended](https://github.com/jakejarvis/hugo-extended) package -- consider [filing an issue](https://github.com/jakejarvis/hugo-extended/issues/new/choose). |

Based on an image to text analysis of the input, we see the following commands being issued:
sudo /opt/lampp/lampp stop && sudo rm /opt/lampp && sudo ln -s 7.4 /opt/lampp && sudo /opt/lampp/lampp start
Now this is being run in a shell extension. These don't have a terminal associated with them, and thus won't have a place to type in a password.
In general for things that are in this situation, you should use something other than `sudo`, such as `pkexec`, and make the entire set of commands into one `pkexec` command line like:
pkexec bash -c '/opt/lampp/lampp stop && rm /opt/lampp && ln -s 7.4 /opt/lampp && /opt/lampp/lampp start'
This will cause the prompt for the sudo password, and then run the set of commands.
So, for the full command line, as asked about in the subsequent comment:
GLib.spawn_command_line_sync("pkexec bash -c '/opt/lampp/lampp stop && rm /opt/lampp && ln -s 8.1 /opt/lampp && /opt/lampp/lampp start'");
*Please note*: testing this was really tedious as I could not get gnome to reload my extension without restarting my entire session. |
