kandi X-RAY | trawler Summary

trawler is a Rust library typically used in Networking, Proxy, Nodejs applications. trawler has no bugs, it has no vulnerabilities and it has low support. However trawler has a Non-SPDX License. You can download it from GitHub.

This crate provides a workload generator that emulates the traffic to lobste.rs. It is a mostly open-loop benchmark similar to TailBench, but it also approximates the partly open-loop designed outlined in Open Versus Closed: A Cautionary Tale by having clients potentially issue more than one query per request. The benchmarker main component is the "load generator". It generates requests according to actual lobste.rs traffic patterns as reported in here, records the request time, and sends the request description to an implementor of Service. When the resulting future resolves, the generator logs how long the request took to process, and how long the request took from when it was generated until it was satisfied (this is called the sojourn time). Trawler is written so that it can either be run against an instance of the lobsters Rails app or directly against a backend by issuing queries. The former is done using the provided binary, whereas the latter is done by linking against this crate as a library an implementing the Service trait. The latter allows benchmarking a data storage backend without also incurring the overhead of the Rails frontend. Note that if you want to benchmark against the Rails application, you must apply the patches in lobsters.diff first.

QUESTION

Swap as image positions with drag and drop

Asked 2020-Apr-15 at 18:19

I have the following script that I put together with part of another, what I need is to change the images by dragging the red heart to the blue one, the blue takes the place of the red and vice versa.

Today the trawler wipes out the old ones.

function allowDrop(ev) {
    ev.preventDefault();
}

function drag(ev) {
    ev.dataTransfer.setData("text", ev.target.id);
}

function drop(ev) {
    ev.preventDefault();

    var id = ev.dataTransfer.getData("text");
    var element = document.getElementById(id)
    var div = document.getElementById(id).parentNode;
    var clonedHeart = document.getElementById(ev.target.id).cloneNode(true);

    ev.target.parentNode.insertBefore(element, ev.target.id.nextSibling)
    document.getElementById(ev.target.id).remove();
    div.appendChild(clonedHeart);

    ev.dataTransfer.clearData();

QUESTION

Odd Progress Value Behaviour when SendMessage Color to Progress Bar

Asked 2017-Nov-01 at 09:31

I am using SendMessage to change the colour of a progress bar. This works ok but I am seeing some odd behaviour related to the progress bar value.

When the bar is green it works as expected, but when it is red or yellow the bar is one block position out of sync with the progress bar value. The example code below steps down through progress bar values from 4 to 0 with progress bar maximum set to 4.

When the bar is green progress value 4 gives a full bar and all integer steps down to zero behave as expected. But when the bar is red or yellow it shows full bar or no bar for value 4 depending on where it was before. It shows FULL BAR for progress value 3, then steps down 1 block out of sync with the value until finally it shows no blocks when the progress value resets to maximum. If this sounds confusing then I'm with you all the way.

I am an avid trawler of SO and have been for many years and to date my questions have always been answered without the need to specifically ask. But while I can find a lot of progress bar questions I can't find any that relate to this issue and it is seriously confusing me. Am I missing something in my code or is this a bug?

The problem seems to be an internal buffering bug as identified by Hans Passant. The bug was reported to Microsoft as suggested by Visual Vincent. The workaround is to Increment(0) after ProgressBar.Value statements. Note that ProgressBar.Refresh and Update do not resolve this issue. The following subroutine is from the VB code example with the Increment(0) fix added.
