wait

Learning to use the fork() command and how to pipe data between a parent and it's children. I am currently trying to write a simple program to test how the fork and pipe functions work. My problem seems to be the correct use/placement of the wait function. I want the parent to wait for both of its children to finish processing. Here is the code I have so far: int main(void) { int n, fd1[2], fd2[2]; pid_t pid; char line[100]; if (pipe(fd1) < 0 || pipe(fd2) < 0) { printf("Pipe error\n"); return 1; } // create the first child pid = fork(); if (pid < 0) printf("Fork Error\n"); else if (pid == 0) /

I have an unordered list, which has maybe 30 items. When one of these items are hovered over, the rest of the list items fade to 30% and the hovered item stays at 100%; when you move away from the list, they all fade back up to 100% and I have managed this. My problems arises when you move from item to item, the other list items fade back up to 100% and then back down to 30%. I want them to stay at 30% unless the user moves away from the whole list. I use the hoverIntent plugin on each list item. I also used jQuery to add a class to the current list item, so I could then fade the rest and

Selenium by default is waiting for all elements to be loaded. Is there any way for waiting for a specific element and then to proceed on? On my test, selenium is waiting with the wait() function for a page to be loaded. sometimes, some images couldn't be loaded from a remote server, while all others element on the page loaded successfully. How can I ask Selenium to ignore waiting all elements except a specific one? Selenium works on a copy of the page's source so it try to wait until the DOM represents what will be the page's full source. For this to work correctly selenium is bases on the

I'm trying to click on a button which is visible on a page by using webdriver wait but webdriver is only able to click on the button once I add a Thread.sleep to the code. I have also checked the button to see whether its visible (True) before I execute my code and it in turn returns = true . //Button Visiblity check: List<WebElement> signOutList = driver.findElements(.xpath(".//*[starts-with(@id,'fulfillment-time-type-section-')]/div[2]//button")); Assert.assertTrue(signOutList.size() > 0); //The code below Doesn't click on the button By timeDropdownButton = By.xpath(".//*[starts-with(@id,

I have a script like this: #!/bin/bash for i=1 to 200000 do create input file run ./java done I need to run a number (8 or 16) of processes (java) at the same time and I don't know how. I know that wait could help but it should be running 8 processes all the time and not wait for the first 8 to finish before starting the other 8. bash 4.3 added a useful new flag to the wait command, -n , which causes wait to block until any single background job, not just the members of a given subset (or all), to complete. #!/bin/bash cores=8 # or 16, or whatever for ((i=1; i <= 200000; i++)) do # create

This question already has an answer here: Combining implicit wait and explicit wait together results in unexpected wait times 2 answers I understand both waits and use of it. But one thing that I could not figure out is : If I put implicit wait for 5 seconds at top and then use explicit wait for an element. Then how selenium will behave. Tried but could not get satisfactory answer on net. Abhinav Kumar Singh First understand the concepts of Explicit and Implicit wait Implicit Wait: An implicit wait is to tell WebDriver to poll the DOM for a certain amount of time when trying to find an element
