timeout

问题 I have a function sending a few requests on the server with a timeout each like: this.httpClient.get(url, { headers: headers }) .timeout(30000) .subscribe( (response) => { ... }, error => { ... } ... ); In case of timeout (30s), everyone request gets canceled, which is understandable. My problem is, that in case of a timeout, the canceled request is not seen as an error, so it doesn't go to the error-part of the request. Are there any possibilities to call a function in this case? 回答1: If you

问题 We have a ASP.net form [.NET 3.5 on IIS 6] that loads controls dynamically. We are able to retain the values in the viewstate as long as the postback happens within 20 minutes . The database also gets updated properly. Everything works as expected. However, If it takes more than 20 minutes for a user to fill out the form, the controls no longer retain their values during postbacks. The session values are intact, the user authentication is also intact. We tried several things 1) Added machine

问题 I have the following object list: mediaList[ {id:1, url:"www.example.com/image1", adType:"image/jpeg"}, {id:2, url:"www.example.com/image2", adType:"image/jpg"}, {id:3, url:"www.example.com/video1", adType: "video/mp4"} ] I need to create a slideshow that has a configurable duration (1s, 5, 10s). So far I can generate a list of the media from the mediaList renderSlideshow(ad){ let adType =ad.adType; if(type.includes("image")){ return( <div className="imagePreview"> <img src={ad.url} /> </div>

问题 Running an almost trivial script in lua with dofile, 10000 times, takes about 52 seconds in this machine, but if i run 10000 times "lua52 script.lua", it takes 3 or 4 times more. I'm aware that there's more system calls involved and other overhead, but what i try to achieve is running scripts with a timeout of let's say 3 seconds, and print out the output. My problem is scripts with infinite loops, intentional or not, for example: while(true) do end Can i make a timeout for a dofile from

问题 I am trying to use ftplib.FTP() with timeout option as some timeout value for a particular hostname. But i am experiencing weird behaviour. To test it i have written a very simple piece of code. import ftplib from ftplib import FTP ftp = ftplib.FTP("google.com",timeout=2) The API document says to enter timeout value in seconds, but it seems that it takes longer than that, for me it almost takes more than 8 secs. Can anybody please explain the behaviour.I am using python2.7 回答1: ftplib.FTP

问题 I am using a SwingWorker to read data over a TCP connection and display when it comes back. new SwingWorker<EnvInfoProto, Void>() { @Override public EnvInfoProto doInBackground() { try { xxx.writeTo(socket.getOutputStream()); return ProtoMsg.parseFrom(socket.getInputStream()); } catch(IOException ignore) { } return null; } @Override public void done() { try { UpdateGui(get()); } catch (Exception ignore) {} } }.execute(); The problem arises when the socket is dead, e.g. after writeTo it waits

问题 I've made one Asp.net MVC website, and I'm very confused between the different timeout settings. What is the difference between: SessionState Timeout in web.config: Application pool timeout Asp.Net Session timeout property Which one should I set if I want to have a timout of (say) 6 hours? All of them? Only some? 回答1: The application pool timeout is the length of time the site has to be idle for before the application pool will shut down the worker process to release resources. The downside

问题 I'm implementing a timeout on an asynchronous operation (a series of network IOs), and I'm not sure which is 'better' (from a allocations / performance) perspective: creating an EventWaitHandle and using RegisterWaitForSingleObject, or just creating a Timer and using its Tick. In my specific case the EventWaitHandle is lazy-created, but obviously it'd have to be instantiated to use WaitForSingleObject. So really this is a question about the resource cost of a WaitHandle + WaitForSingleObject

问题 I have use SNMP v1 and 2c for network discovery of printers by sending broadcast message with community "public" and it works just fine, but when I send broadcast message with version 3 of the protocol I got timeout error. Do somebody share example of SNMPv3 device discovery? Thank you. 回答1: Two things: 1) Doing a broadcast SNMPv1/v2c is actually not defined to work in the protocol. Cheap implementations will simply respond, as you've found, to any packet it sees that the kernel accepts to
