QUESTION
I am trying to stream data from a large csv file into readline. I tried just piping the readStream from s3 into the readline input, however I faced an error with S3 only allowing a connection to stay open for a certain amount of time.
I am creating the stream from s3 like so:
...ANSWER
Answered 2022-Jan-07 at 18:01I was able to work in a solution for this using the AWS S3 Range property and creating a custom readable stream with NodeJS Stream API.
By using this "smart stream" I was able to grab data in chunks in separate requests to the S3 instance. By grabbing the data in chunks, I avoided any timeout errors as well as creating a more efficient stream. The NodeJS Readable Super class handles the buffer so as to not overload the input to readline. It also automatically handles the pausing and resuming of the stream.
This class made it possible to stream large files from AWS S3 very easily:

I have a component which allows a user to download an excel file after clicking a link. It works and everything is fine, but I don't know how to write a test for this component. I want to write a test to check if after pressing a link a file is sent to a client.
And so, my component looks like this
...ANSWER
Answered 2021-Dec-07 at 20:09You should use tester.getLastResponse() and assert on its properties.
tester.getResponse() is the MockHttpServletResponse that will be used for the next HTTP call.
Some dummy examples:

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverUrl);
request.Method = WebRequestMethods.Ftp.ListDirectory;
var response = (FtpWebResponse)request.GetResponse();
Stream rStream = response.GetResponseStream();
StreamReader reader = new StreamReader(rStream);
string fileNames = reader.ReadToEnd();
List ls = fileNames.Split(new string[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries).ToList();
for (int i = 0; i < ls.Count; i++)
Console.WriteLine(ls[i]);
ANSWER
Answered 2020-Nov-26 at 03:25I have written the related code in the msdn forum like: download each file in folder.
You can use the FtplistFile method to get a list of all files in the ftp server.
Here is a code example I modified.
QUESTION
I can't seem to get my code to work. I would like to be able to live stream sound with python to another computer, and my code just quits on windows. How would I be able to fix this?
dev box: Linux Mint 20 64-bit
test computer: Windows 10
I am using pyaudio to record sound and while it is recording, send it to another computer. I am getting no audio output and both windows & linux will just randomly stall the application.
Linux errors:
...ANSWER
Answered 2020-Nov-17 at 21:03There wasn't any problem with the connection getting aborted, but rather a problem with how I was receiving sound.
In my play thread, in the while loop, I changed my first line of code from data = ps.recv(64 * 2 *2) I needed to put data = connection.recv(64 * 2 * 2) instead. That fixed my problem, and now I just need to learn some more audio coding, because now I get "alsa underrun" errors.
QUESTION
The following snippet creates a readable stream from a file and then listens to the readable event to start receiving data from the stream.
ANSWER
Answered 2020-Apr-23 at 02:22will it always return the tokens from the new line or could be it a partial result
No, it will not always return a full line. You have to be prepared to get a partial line. If you want line by line results, you can use the Readline interface and it will handle partial result buffering and only tell you when it has a whole line.
What is the default number of bytes returned from the stream or how does it work?
A stream uses an internal buffer (which you have some control over). The call to .read() is non-blocking. It will return as many bytes as it has in its buffer, up to the amount you asked for. But, if the buffer doesn't have very many bytes in it and particular as you get to reading towards the end of the buffer, you absolutely can get partial results before the stream has received the next set of bytes from the file.
So, there is no automatic "default" value for how many bytes will be ready upon the first read. It depends upon a whole bunch of timing considerations including how much time has elapsed since you opened the stream and when you are reading and how fast your drive is and how much contention there is for both CPU and I/O on your system. If you don't read for a little while, the stream should fill its internal buffer. If you read immediately, it might have not yet put any or much into the buffer yet.
Does this mean that a chunk size will be no less than 64 * 1024 bytes?
No, it means that a chunk size will be no larger than that. For a readable stream, the highWaterMark determines the maximum amount of data that the stream will buffer ahead of your actual read() calls. Once, the stream fills up that buffer, it stops reading automatically until you read some of that data out of the internal buffer.
QUESTION
I'm running this simple Python program to merge the output lines from two subprocesses:
...ANSWER
Answered 2020-Mar-13 at 05:57The root reason is that you use sys.stdout.buffer which has a buffer internally, and therefore we could not see the result immediately.
We could explicitly flush the result after write. To put sys.stdout.buffer.flush() after buffer.write(). Or just use print(stream.readline()) rather than sys.stdout.buffer.

Install rstream
You can use rstream like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
