kandi X-RAY | xcp Summary
xcp is a (partial) clone of the Unix cp command. It is not intended as a full replacement, but as a companion utility with some more user-friendly feedback and some optimisations that make sense under certain tasks (see below). Warning: xcp is currently beta-level software and almost certainly contains bugs and unexpected or inconsistent behaviour. It probably shouldn't be used for anything critical yet.

QUESTION
I wrote HttpServlet doGet method this is the servlet:
...ANSWER
Answered 2022-Mar-29 at 10:13A few things ...
Compression done via a Servlet Filter can no longer be done in Servlet 3.1+ (You can thank the changes necessary for Async I/O to the spec for that).
Use the Jetty built-inGzipHandler
instead.Don't set
Content-Length
response header when doing compression (You would have to pre-compress to know the actual content length)Set the
Content-Type
response header to a value that is appropriate for your content.Set ALL response headers BEFORE you write the the response. You cannot change the headers after the response body content is written (the
HttpServletResponse.isCommitted()
tells you if you can change the response anymore)
QUESTION
Hi I would like to scrape a single table containing 100 rows, however with rvest it only seem to get up to 20 rows and it stops. Interestingly it captures the first column for the entire table however after row 20 the rest of the columns are NA
...ANSWER
Answered 2021-Dec-14 at 04:11The issue here is that the page uses Javascript to add rows to the table as you scroll down the page, so data for all rows is not present when you read the page using read_html
.
The first 200 rows of data are contained in the page source code inside this tag, as JSON format:

I am currently running a Java Spring Boot program that should return a response that includes two Excel files (.xlsx) as ByteArrayOutputStream's in the ServletOutputStream as Content-Disposition: attachment;
However, upon returning that response to chrome, it isn't downloading anything.
The Excel files are generated using the Apache POI and then they're being written to a ByteArrayOutputStream.
Here's my code on the file generation
...ANSWER
Answered 2021-Sep-12 at 13:50You are returning multiple files directly. To respond multiple file compress them and send them as zip file. Also in the code you are first setting the content type and then updating the contentType.

QUESTION
I have a UWP Windows store app with a WinUI 2.0 tree view control. I load the sub directory structure in the treeview based on user selection of a folder.
The problem I am facing is that the application crashes when I select certain folders on my dev machine. It works fine for other folders. I can see the same crash with some of my app users in the windows store diagnostic data.
Here the call stack from my machine for the crash:
...ANSWER
Answered 2020-Jun-10 at 03:26I was able to figure out what I was doing wrong - posting it here so that it can help others.
I was allowing users to filter out items in the tree view using other controls in the form, and I had implemented it such a way that on a node, I generate the list of children of a node when the bound property was accessed.
This meant that I returned a new list of children each time the bound property was accessed, and the framework expects the list of children to be stable between immediate calls.
The solution was to cache the list of children of a node so that I only generate a new list when something actually changed.
