execution

问题 Is there a way to determine if the process may execute a file without having to actually execute it (e.g. by calling execv(filepath, args) only to fail and discover that errno == EACCES )? I could stat the file and observe st_mode , but then I still don’t know how that pertains to the process. Ideally, I’m looking for a function along the lines of get_me_permissions(filepath, &status); // me: the process calling this function // when decoded, status tells if the process can read, write, and

问题 I have a wordpress page. I have a number of links which go to PayPalObjects. PayPalObjects requires that you put code in the footer of the page with triggers to IDs for the elements which trigger a purchase. eg... <a id="buysong_4" target="PPDGFrame" title="Click here to buy this song now.">$</a> ...and then in the footer of the page: <script type="text/javascript"> var embeddedPPFlow1 = new PAYPAL.apps.DGFlow( {trigger : 'buysong_1'}); function MyEmbeddedFlow(embeddedFlow) { this

问题 I have a jsonp ajax call which got executed and returns the data to my main function. This is done in the success function by calling that.mainfunction(newData); That means that the main function is called the second time and I think that I'm running therfore in a time/execution problem. While running in the first iteration newData is empty and gets returned empty to the main function. The main function by this framework I must use. So another control is trying to invoke the getter which is

问题 As far as I've been led to understand, x++ is essentially a terser way of saying x = x + 1 . So far, so clear. In front-end Javascript, I've occasionally seen ++x — I seem to remember from a jsPerf test I can no longer find (how does one Google ++ effectively?) that this somehow had a small performance benefit in a particular version of IE, and let it go at that. However I've recently encountered something that speaks of a weird quirk in execution order (JS code): var x = 1; console.log(x++);

问题 I have a web application for which I have done automation tests in Selenium using TESTNG on admin module and user module. Now I need to run the java files continuously one after the other(1st admin then the user module). No methods are common between them. I just want to run the user module java file as soon as the admin module has finished running. 回答1: You can use dependsOn attribute of TestNG if one test is dependent on pass/fail of previous one OR you can use groups attribute. Refer

问题 I'm close to the max execution time on my server and I'm not allowed to change it. The script downloads data and writes it to files. The potential problem is that the script can reach maximum execution time during writing a file to disk. Therefore it is essential to me to know if the termination of a script after reaching max allowed time for exec. is immediately and can lead to an incomplete file stored at disk or the script is terminated right after last instruction/function ends so I can

问题 I am starting a loop in python, and after I start the loop I want the execution of code after the loop to carry on, while the loop keeps looping (in the 'background'). x=True while x: #do some output sleep(1) #ask for input or something if input()=='something': x=False So in that example, #do some output will keep happening while input is asked for. Is this possible in python? Are there any work-arounds that could achieve this? 回答1: Following OP's wish I'm posting the answer. :) There are

问题 I am facing the following problem: I am writing a java-application in Eclipse. Inside my application I want to start a cmd command: C:/Users/User1/Content-Integration Testing Framework/JDBC Connector/bin/connect -h The command 'connect -h' is a an enterprise internal application which works fine. If I would use a comand line a would have to chance my current directory like that: cd C:/Users/User1/Content-Integration Testing Framework/JDBC Connector/bin/ and afterwards I would just type

问题 On 2 occasions in the past month, we have managed to hit our daily limit on asynchronous apex executions. Salesforce temporarily increased our limit to 425000 but it will be scaled down to 250000 in a week's time. Once we reach the limit, a lot of the SF functions will fail and this has tremendously impacted both internal staff and external customers. So to prevent this from happening in the future, we need to create some kind of alert in Salesforce to monitor our daily asynchronous apex
