timeout

问题 So I have a control (a map) on an aspx page. I want to write some javascript to onload setup the following: when mouse stops on control = some code when mouse moves = some code (but only if the move is longer than 250 mil sec) This works to trigger code on stop and then on move... function setupmousemovement() { var map1 = document.getElementById('Map_Panel'); var map = document.getElementById('Map1'); map1.onmousemove = (function() { var onmousestop = function() { //code to do on stop },

问题 I have 5 nodes in my ring with SimpleTopologyStrategy and replication_factor=3 . I inserted 1M rows using stress tool . When am trying to read the row count in cqlsh using SELECT count(*) FROM Keyspace1.Standard1 limit 1000000; It fails with error: Request did not complete within rpc_timeout. It fetches for limit 100000. Fails even for 500000. All my nodes are up. Do I need to increase the rpc_timeout ? Please help. 回答1: You get this error because the request is timing out on the server side.

问题 I am iterating through a large test matrix in MATLAB and calling second-party proprietary software (running in MATLAB) each time. I cannot edit the software source code. Sometimes, the software hangs, so I want to exit it after a certain amount of time and move on to the next iteration. In pseudocode, I'm doing this: for i = 1:n output(i) = proprietary_software(input(i)); end How can I skip to the next iteration (and possibly save output(i)='too_long' ) if the proprietary software is taking

问题 I can set the timeout of my HttpClient object directly with HttpClient.Timeout but I've recently read about the WebRequestHandler class which is a derivative of HttpClientHandler . WebRequestHandler has a ReadWriteTimeout property. How will this affect the operation of the request when used alongside HttpClient.Timeout ? 回答1: When you perform a SendAsync the HttpClient.Timeout is placed on the CancellationTokenSource . This means this timeout is for the entire async operation. On the other

问题 I am wondering whether I can set a timeout value for UdpClient receive method. I want to use block mode, but because sometimes udp will lost packet, my program udpClient.receive will hang there forever. any good ideas how I can manage that? 回答1: What Filip is referring to is nested within the socket that UdpClient contains ( UdpClient.Client.ReceiveTimeout ). You can also use the async methods to do this, but manually block execution: var timeToWait = TimeSpan.FromSeconds(10); var udpClient =

问题 I set up my first Ubuntu Server with Ubuntu 16.04, nginx, php7.0, MariaDB, nextcloud and external DynDNS using this tutorial here: Install Nextcloud 9 on Ubuntu 16.04 Everything worked fine but since I restarted the server the next day, nextcloud just shows me a blank page. After clicking through all logs of nginx, MariaDB and nextcloud, I found out that the mysql service just doesn't start. So run service mysql start and everything worked fine again (calling nextcloud from server as well as

问题 I open a TCP socket and connect it to another socket somewhere else on the network. I can then successfully send and receive data. I have a timer that sends something to the socket every second. I then rudely interrupt the connection by forcibly losing the connection (pulling out the Ethernet cable in this case). My socket is still reporting that it is successfully writing data out every second. This continues for approximately 1hour and 30 minutes, where a write error is eventually given.

问题 I have recently inherited a couple of applications that run as windows services, and I am having problems providing a gui (accessible from a context menu in system tray) with both of them. The reason why we need a gui for a windows service is in order to be able to re-configure the behaviour of the windows service(s) without resorting to stopping/re-starting. My code works fine in debug mode, and I get the context menu come up, and everything behaves correctly etc. When I install the service

问题 We have had an issue with a block of code that responds poorly in the face of slow databases (It craps the bed on a query timeout). We have created a patch, and are in the process of running it through regression. We can't get a timeout. I've opened a transaction from SQL Mgmt Studio and updated every row to lock them, but that doesn't cause INSERTs to timeout (which is what I need). Can I get a table-level lock easily via T-SQL? Or do I have to fiddle around in master? Or can I easily force
