debugging

问题 I have two spring boot applications running in the same container with the same codebase but with different profiles. One application is for production and the other is for test. Each application run under a different virtual host. The container is tomcat and I've added this in setenv.sh : CATALINA_OPTS="-agentlib:jdwp=transport=dt_socket,address=5005,server=y,suspend=n $CATALINA_OPTS" With eclipse, I can create a debug configuration for Remote Java Application. I've set the Host to the test

问题 For one of my dissertation's data collection modules, I have implemented a simple polling mechanism . This is needed, because I make each data collection request (one of many) as SQL query, submitted via Web form, which is simulated by RCurl code. The server processes each request and generates a text file with results at a specific URL ( RESULTS_URL in code below). Regardless of the request, URL and file name are the same (I cannot change that). Since processing time for different data

问题 So... I got this npm package I'm developing for the sails framework. The NPM package is: https://github.com/stuk88/ecobill-hook-cms Its loaded as a hook in sails. what is the best way to debug the package with breakpoints inside Webstorm? 回答1: Steps: Go to Run>Edit configurations Click on (+) and pick Node.js Select one node interpreter in case is emtpy set your working directory Javascript file must be app.js in the same working directory application parameters (I usually set --dev )

问题 I found it really weird that traceId returns the message string itself. Why would anyone want to do that? Is there a common scenario where traceId would come in handy? 回答1: EDIT: Credits to David who drew attention on the fact that my traceId' is exactly traceShowId . Hence, traecId is simply the String -> String monomorphic version of the polymorphic traceShowId :: Show a -> a -> a , which also strips the printed string from quotes. Old answer: One way to interpret traceId is that it's a

问题 I have a terrible repeating error of 404 not found for a GET request. The call looks like this in the JavaScript console GET some_path/undefined 404 ( Not Found ) and all it states to the right of that is: undefined:1 It keeps repeating over and over, it does not stop. How can I determine what line is trying to make this call? 回答1: On chrome you can add breakpoints on XHR and then you should see the callstack. Go to developer tools -> "sources" tab -> "XHR Breakpoints" and add a breakpoint

问题 From my talks with experts here (Link1, Link2), I think I need to do a conditional binary logistic regression. I have sorted my data in a way that each control is exactly followed by the counterpart treatment case and the data is in long format. My design is detailed in the above two links plus these two more links: Link3, Link4 edit: later I saw that sorting is not at all important because the sorted and non-sorted data resulted in the same output. My syntax is the following. The code runs

问题 I've been using PHP sessions on a site I'm building and it's been working fine until strangely this morning: One page one: session_start(); $_SESSION['myarray']=$myarray; Then on page two I try: session_start(); print_r($_SESSION['myarray']); however it shows an empty array. I've checked on page 1 and the array has values in it. Any ideas on what to look for to debug this? Thanks. (SOLVED): Eventually solved the problem - that line has to be at the very top of each page where you use any

问题 Hello I have seen that C++ Vector vs Array (Time). On my mac the vector take times to be defined but after the comparison give vector for winner. How it works ? I was said int[] are faster than dynamic vector ? #include <iostream> #include <vector> using namespace std; #define N (100000000) //int sd[N]; int main() { clock_t start; double temps; static int sd[N]; start = clock(); for (unsigned long i=0 ; i < N ; i++){ if(sd[i]==3) ; } temps = (clock() - start) / (double)(CLOCKS_PER_SEC / 1000)

问题 I had a fully working USB debugging between my Windows 10 PC and my Nexus 7. However after a cleanup of my drives I somehow managed to mess it up. (Presumably I deleted the .android folder containing the RSA keys) I should still be able to reset the keys and get the RSA popup just like in the case of a new computer. However I get no popup and I have tried nearly everything. The PC: Windows 10 64 bit adb version 1.0.32 (latest) Latest Google usb drivers The tablet: Nexus 7 2012 wifi edition
