timeout

问题 Is there a way you can abort a block of code if it's taking too long in PHP? Perhaps something like: //Set the max time to 2 seconds $time = new TimeOut(2); $time->startTime(); sleep(3) $time->endTime(); if ($time->timeExpired()){ echo 'This function took too long to execute and was aborted.'; } It doesn't have to be exactly like above, but are there any native PHP functions or classes that do something like this? Edit : Ben Lee's answer with pcnt_fork would be the perfect solution except

问题 I have a div in my view , I want to execute a function on ng-click() which turns the background for the div to 'color a' for 30 seconds if there's no action taken then for 60 seconds then change to 'color b' and if no action is taken beyond 120 seconds just hide the div.(this can be done via adding/removing classes as well ) In essence I'm looking to execute a sequence of $timeouts in angular where one timeout leads into another. Any help on that would be hugely appreciated. Thanks. 回答1: I

问题 I have been searching on this but it is surprisingly hard to come by a straight answer to this (as php has a lot more info on this topic it seems).. I need to make my perl script die after a specified number of seconds because, as it is now, they are running too long and clogging up my system, how can I make it so the entire script just dies after a specified number of seconds? I know about external solutions to kill the script but I would like to do it from within the perl script itself.

问题 I am having a problem with a network request that should timeout, but the method is not called. The request is as follows: #define kCONNECT_TIMEOUT 20.0 request = [NSMutableURLRequest requestWithURL: aUrl]; [request setHTTPMethod: @"POST"]; postData = [jsonData dataUsingEncoding:NSASCIIStringEncoding]; [request setHTTPBody:postData]; [request setValue:@"text/xml" forHTTPHeaderField:@"Accept"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setCachePolicy

问题 I want to be able to join() the Queue class but timeouting after some time if the call hasn't returned yet. What is the best way to do it? Is it possible to do it by subclassing queue\using metaclass? 回答1: Subclassing Queue is probably the best way. Something like this should work (untested): def join_with_timeout(self, timeout): self.all_tasks_done.acquire() try: endtime = time() + timeout while self.unfinished_tasks: remaining = endtime - time() if remaining <= 0.0: raise NotFinished self

问题 Does anybody know how to disable or change the timeout limit for CUDA kernels under Ubuntu 12.10? (With current versions of Windows one can set the timeout limit in the registry.) Please tell me as well if there is no possibility to do this with Ubuntu. The only results of my previous search are the following: running the CUDA kernel without a graphical display is attached to the GPU splitting the kernel into smaller ones to avoid exceeding the time limit Both solutions are no option for me
