timeout

问题 I can not find how to work properly with mq_timedreceive, can anyone give me an example? ssize_t mq_timedreceive(mqd_t mqdes, char *msg_ptr, size_t msg_len, unsigned *msg_prio, const struct timespec *abs_timeout); I want timereceive to do not spent more than 20 seconds waiting. Thank you very much. 回答1: struct timespec tm; clock_gettime(CLOCK_REALTIME, &tm); tm.tv_sec += 20; // Set for 20 seconds if( 0 > mq_timedreceive( fd, buf, 4096, NULL, &tm ) ) { ... } Take a look at the full description

问题 On nodejs.org socket.setTimeout, it says When an idle timeout is triggered the socket will receive a 'timeout' event but the connection will not be severed. But when I test code like this: var http = require('http'); server = http.createServer(function (request, response) { request.socket.setTimeout(500); request.socket.on('timeout', function () { response.writeHead(200, {'content-type': 'text/html'}); response.end('hello world'); console.log('timeout'); }); }); server.listen(8080); The

问题 We are running ECS as container orchestration layer for more than 2 years. But there is one problem which we are not able to figure out the reason for, In few of our (node.js) services we have started observing errors in ECS events as service example-service (instance i-016b0a460d9974567) (port 1047) is unhealthy in target-group example-service due to (reason Request timed out) This causes our dependent service to start experiencing 504 gateway timeout which impacts them in big way.

问题 I have configured HAProxy (1.5.4, but I tried also 1.5.14) to balance in TCP mode two server exposing AMQP protocol (WSO2 Message Broker) on 5672 port. The clients create and use permanent connection to the AMQP Servers, via HAProxy. I've changed the client and server TCP keepalive timeout, setting net.ipv4.tcp_keepalive_time=120 (CentOS 7). In HAProxy I've setted timeout client/server to 200 seconds (>120 seconds of the keepalive packets) and used the option clitcpka. Then I've started

问题 I am fiddling with Linux command "timeout": it simply stops a long running command after a given seconds. But I would like to timeout not only a command, but a group of commands. I can group command in two way ( ) and { ;} however none of the following works: timeout 1 { sleep 2; echo something; } timeout 1 ( sleep 2; echo something ) How can I do that with grouping? 回答1: timeout is not a shell utility and it does not do shell-style processing. It must be given one single command to execute.

问题 what I want to do here is loop until "x" is pressed. I am aware of CHOICE with the /T option. But CHOICE has too long of a timeout for a animation that I want to play. Here is a example : @echo off cls set frame=2 :loop cls type [%frame%].txt [Here is where it would test for the keystroke.If keystroke "x" is detected,goto MENU. If not pressed within a quick second,continue.] set /a frame=%frame%+1 goto loop note: The frames are for a animation,so do keep in mind that the timeout must be

问题 I am making a program in C with GTK and Glade for a serial communication. I am having problem using g_timeout_add. For example I have a function serial_data() which contain my serial data and I have a button handler on_update_button_clicked() . So till now I have done that if update button is clicked, gtk_timeout should run. But it running just for one time. on_update_button_clicked(GtkButton *Update_Button) { //2nd argument is serial_data function which contain actual data g_timeout_add(250

问题 I've installed KnpSnappyBundle on an existing Symfony 3.4 project. I've tested the PDF generator with a HTML twig with text only, no images, no css, no js : it works fine. Then I've added (to the twig) an image and a Bootstrap.Css file using absolute URL (i'm working on localhost): the PDF generator displays an ugly error : The process "wkhtmltopdf --lowquality '/tmp/knp_snappy5aeb39ad71e767.56551505.html' '/tmp/knp_snappy5aeb39ad71ebf0.62787578.pdf'" exceeded the timeout of 60 seconds.

问题 I have a function that should not take too long to run. I would like to set a timeout limit on it. I can find one proposed solutions on the internet. See the following SO post. Timeout on a function call The solution uses signals, which is not available on Windows. There is a similar use of signals for making a ticker, which has a windows port as explained on this SO post: python: windows equivalent of SIGALRM this is not an answer to the timeout directly, but could be adapted to work for
