QUESTION
SpringBoot v2.5.1
There is an endpoint requesting a long running process result and it is created somehow
(for simplicity it is Mono.fromCallable( ... long running ... ).
Client make a request and triggers the publisher to do the work, but after several seconds client aborts the request (i.e. connection is lost). And the process still continues to utilize resources for computation of a result to throw away.
What is a mechanism of notifying Project Reactor's event loop about unnecessary work in progress that should be cancelled?
...ANSWER
Answered 2021-Jun-15 at 09:06fromCallable doesn't shield you from blocking computation inside the Callable, which your example demonstrates.
The primary mean of cancellation in Reactive Streams is the cancel() signal propagated from downstream via the Subscription.
Even with that, the fundamental requirement of avoiding blocking code inside reactive code still holds, because if the operators are simple enough (ie. synchronous), a blocking step could even prevent the propagation of the cancel() signal...
A way to adapt non-reactive code while still getting notified about cancellation is Mono.create: it exposes a MonoSink (via a Consumer) which can be used to push elements to downstream, and at the same time it has a onCancel handler.
You would need to rewrite your code to eg. check an AtomicBoolean on each iteration of the loop, and have that AtomicBoolean flipped in the sink's onCancel handler:
QUESTION
I'm creating 2 pages (Summary and Cycles pages) using react.js.
On the Summary page, there is a column named CN that every item links to the Cycles page.
Summary page has a path /route/summary/location=abc and Cycles page has a path /route/cycle/location=abc/deviceId=4410
For example, if I click the value from CN column in the first row of the table inside the Summary page, I will be redirected to the Cycles page with the path /route/cycle/location=abc/deviceId=4410.
In the Summary page, I use https://github.com/react-bootstrap-table/react-bootstrap-table2 for the table component and I use a columnRenderer function inside columns.js to render a custom item inside the table like this one:
How can I put the pathname (example "abc") to a Link component inside cnColumnRenderer function in columns.js?
Summary page with the path: /route/summary/location=abc
Cycles page with the path: /route/cycle/location=abc/deviceId=4410
Error because of invalid hook call while rendering the Summary page
My Code:table code inside Summary page (inside Summary.js):
hint: focus on columns variable from './columns' and its implementation
ANSWER
Answered 2021-Jun-15 at 05:17React hooks are only valid in React functional components, not in any callbacks, loops, conditional blocks. If you need the location data in the callback it needs to be passed in.
From what I can tell it seems you need to move the columns.js code into the main component so the location values can be closed over in scope.

...ANSWER
Answered 2021-Jun-12 at 17:13The simplest way to do this is like you mentioned moving the reading outside of the loop in a separate task. In this paradigm you'll need to update a local variable with the latest data, making your code look something like this:

Answered 2021-Jun-11 at 17:59data is an array, so it likely won't have an option property.
It seems prizeNumber is the psuedo-random index, so to display the option access it from the data array.
QUESTION
So the problem I am having is this, here I have a pushLogic, so the thing I am trying to achieve is this, when I press the button I wanna start the animation, I want spinner to start spinning but for some reason it is not doing it.
...ANSWER
Answered 2021-Jun-11 at 17:36You need to separate out the spinner css class from the animation css class, and apply the animation class onClick.

QUESTION
I understand why it's important that all nodes on the Ethereum mainnet must execute any smart contract function call which changes the internal state of the contract or the chain. (For example, transfers from one account to another ec.)
What I'm wondering is, if its true that every node must execute every function called on any smart contract, even if the function doesn't result in a state change.
For example, if an ERC721 smart contract has a function "getName()" which just returns the name of the artwork the NFT represents which is stored in the NFt. Let's say joe connects to the network, and wants executes getName() on a contract. Does that mean that all 9,000 nodes end up spinning cycles executing getName(), even though Joe only needs it to be executed once? Does the gas cost of running "getName()" compensate each of the nodes for the overhead of running "getName()"? If that is true (that every node gets paid) will gas get even more expensive as more nodes join the pool?
Is one of the reasons gas prices are high is because of the inefficiency of every node having to execute every function called on a smart contract, even those that have no effect on state?
If so it would seem to be a very (and perhaps unnecessarily) expensive proposition to execute a computationally intensive but "pure" (no side effects) function on Ethereum, right?
Thanks. apologies for the possibly naive question!
...ANSWER
Answered 2021-Jun-11 at 08:41There's a difference between a transaction (can make state changes - but doesn't need to), and a call (read-only, cannot make state changes).
I'll start with the call simply because it's easier.
When a node performs a call, it executes the contract function that most likely reads from storage, stores to memory, and returns from memory.
Example:
QUESTION
I have an overarching Bash script where there are 3 main processes that are executed within the script:
- Spin up an ec2 instance (lets say ec2-1) which will pull data from a private s3 bucket (in the same region: us-east-1) and run some programs.
- Spin up an ec2 instance (lets say ec2-2) which will pull data from a public amazon s3 bucket (in the same region: us-east-1) and run some programs.
- Spin up an ec2 instance (lets say ec2-3) which will pull data from a private s3 bucket (separate from 1), but still in region: us-east-1) and run some programs.
To ensure that each, individual process worked, I ran them all separately. For example, in my bash script, I would run only process 1) and ensure it completes from start-to-finish. After that completes, I would test 2), wait for this to run through completely, and then test 3) to ensure that runs through completely. Everything works fine, and have it all working well. Download speeds are in excess of 25-30 MB/s, which is perfect since a lot of data is being moved to/from s3 buckets.
Now I am at the stage where I attempt to run 1, 2, and 3 together all within the same Bash script. Note: all three ec2 instances SHOULD be independent from one another as they all have their own unique instance-id but are all in the same region (us-east-1). However, when I run all 3 at once, there is something that causes download speeds to/from the s3 buckets to become VERY slow - from ~ 25MB/s to 1 kB/s, and sometimes even completely stopping. It is interesting because 1) and 3) are pulling data from a private bucket, whereas 2) is pulling data from Amazon's public s3 bucket, yet ALL THREE instances have slow/stopped download speeds. I have even increased all of the three ec2 instances to m5dn.24xlarge, and the download speeds are still abysmal.
I also tried to run two separate instances of 1), 2), or 3), and they perform slower as well. For example, if I run 1) for two separate dates (with two separate instance-id's), the speed is lower compared to if I just run one instance of 1).
My question is: how/why would this be happening? Any feedback / info would be very helpful.

Answered 2021-Jun-10 at 22:36The issue was an endpoint was not setup correctly so communication was lacking.
QUESTION
My dataflow job has both source & sink as synapse database.
I have a source query with joins & transformations in the dataflow while extracting data from the synapse database.
As we know, dataflow under the hood will spin up the databricks cluster to execute the dataflow code.
My question here, the source query I am using in the data flow will that be executed on the synapse db/databricks cluster?
...ANSWER
Answered 2021-Jun-10 at 19:03The data flow requires a compute context, which is Spark. When you use a query in the transformation, that query will get executed from that Spark cluster, which essentially gets pushed down into the database engine for resolution.
QUESTION
As we know, xv6 doesn't let a spinlock be acquired twice (even by a process itself).
I am trying to add this feature which lets a process to acquire a lock more than once.
In order to reach this, I am adding an attribute called lock_holder_pid to the struct spinlock which is supposed to hold the pid of the process which has acquired this lock.
The only file I have changed is spinlock.c
Here is my new acquire() function:
ANSWER
Answered 2021-Jun-10 at 09:15This is simply because you are trying to have access to a field of a null struct (myproc()->pid).
As you may know, myproc() returns a process running on the current processor. If you look at main.c, you may notice that the bootstrap processor starts running there. Therefore, if we can find a function which calls the acquire() function before setting up the first process, the problem will be solved.
If you take a close look at the kinit1 function, you can realize that the acquire function is called in it. Consequently, we found a function that uses the acquire function, even before initializing the ptable struct. Therefore, when you try to access the myproc() value, it is not initialized yet.

Install spin
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
