Does PHP flush work with jQuerys ajax?

这一生的挚爱 提交于 2019-11-29 15:33:12
I have created a page in which I use the PHP function flush(), to output data to the browser the second the data is echoed. I'm also calling this page using jQuery's ajax function. It works, but jQuery doesn't output anything until the entire page has executed, which kind of removes the functionality of flush(). How can I fix this? My ajax call looks like this: jQuery.ajax({ type: "get", url: url, data: postdata, success: function(retval) { jQuery('#retdiv").html(retval); } }) Here you have 2 plugins for streaming: JQUERY AJAX HTTP STREAM and JSTREAMPLUG . http://plugins.jquery.com/taxonomy

欢迎大家关注我的微博 http://weibo.com/hotbain 会将发布的开源项目技术贴通过微博通知大家,希望大家能够互勉共进!谢谢!也很希望能够得到大家对我博文的反馈,写出更高质量的文章!! write处理流程 业务逻辑handler调用context的write方法,将欲发送的数据发送到带发送缓冲区中. 看看write流程的触发代码(就是在一个业务handler中调用一下write方法即可): public class DiscardServerHandler extends ChannelHandlerAdapter { @Override public void channelRead(final ChannelHandlerContext ctx,final Object msg) throws Exception { ByteBuf bufferBuf =(ByteBuf)msg; System.out.println(new String(bufferBuf.array())); ctx.channel().write(bufferBuf); } 追踪一下,ctx.channel().write(bufferBuf)的实现(假设out pipeline中没有其他的encode handler了,),我们会看到,最终会由AbstractUnsafe

Flushing fopen()'ed files opened in update mode,between read and write operations.Explicit flushing needed?

I have read this about the switch between read and write operations(and vice-versa) for files opened for update using fopen() ( LINK ) "For files open for update (those which include a "+" sign), on which both input and output operations are allowed, the stream should be flushed (fflush) or repositioned (fseek, fsetpos, rewind) between either a writing operation followed by a reading operation or a reading operation which did not reach the end-of-file followed by a writing operation." There are two things mentioned here that I would like to highlight the stream should be flushed (fflush) or

Need Python 3.4 version of print() from __future__

爱⌒轻易说出口 提交于 2019-11-29 14:46:20
Currently, when I from __future__ import print_function from Python 2.7.6, I apparently get a version of print() prior to the addition of the flush keyword argument, which went in Python 3.3 according to the docs . The Python3 installed in my system (Ubuntu) is Python 3.4, and I verified its print() function has the flush argument. How do I import the print() function from 3.4? From where is __future__ getting the older print function? You cannot get the version from 3.4 imported into Python 2.7, no. Just flush sys.stdout manually after printing: import sys print(...) sys.stdout.flush() Or you

Is there a way to flush the DNS cache from a C# WPF app? (on XP, Vista, Win7)

Is there a way to flush the DNS cache from a C# WPF app? The application would be running on either XP, Vista, or Windows 7. This may be the poor-man's solution, but you could use System.Diagnostics.Process to launch ipconfig /flushdns . You can use a function from Microsoft's "dnsapi.dll". This will allow you to do this completely programmatically: using System.Runtime.InteropServices; [DllImport("dnsapi.dll",EntryPoint="DnsFlushResolverCache")] private static extern UInt32 DnsFlushResolverCache (); public static void FlushMyCache() //This can be named whatever name you want and is the

How do you flush Python sockets?

问题 I've written a server in Python that is meant to send data to the client in the form "Header:Message" I would like to be able to have each message sent individually so that the client will need to perform minimal work in order to read the "header" and the "message" Unfortunately, I can't figure out how to properly flush a python socket so when I have multiple sends execute in quick succession the messages get lumped together in the socket buffer and sent as one big chunk. Example: Server

Why doesn't python3's print statement flush output when end keyword is specified?

from sys import argv, stdout as cout from time import sleep as sl print("Rewinding.......",end = '') # If end is given output isn't flushed. But why? cout.flush() for i in range(0,20): sl(0.2) print(".",end='',flush = True) #No output is printed if flush wasn't specified as true. print("Done") #Output is by default flushed here When I specified end and sleep, I noticed that output wasn't flushed until next print where it was by default flushed. Why does this happen? I had to manually flush the output. In fact this is the default behavior of the underlying stdio functions. When the output is to

No console output on cout

Good morning, I have a problem with Eclipse IDE for C/C++ Developers. I'm writting a smal tool for converting Strings. While testing on some point eclipse stopped to give console output . e.g.: cout<<"test"; doesn't get displayed. But it's not every where... another example: // File path as argument int main(int argc, char* argv[]) { if (argc != 2) { cout << "ERROR: Wrong amount of arguments! Only one allowed...\n"; cout << "\n" << "Programm closed...\n\n"; exit(1); } CommandConverter a(argv[1]); cout<<"test"; a.getCommandsFromCSV(); cout<<"test2"; return 0; } The error message is displayed

does close() imply flush() in Python?

。_饼干妹妹 提交于 2019-11-29 09:03:43
In Python, and in general - does a close() operation on a file object imply a flush() operation? Martin Wickman Yes. It uses the underlying close() function which does that for you ( source ). NB: close() and flush() won't ensure that the data is actually secure on the disk. It just ensures that the OS has the data == that it isn't buffered inside the process. You can try sync or fsync to get the data written to the disk. Yes, in Python 3 this is finally in the official documentation , but is was already the case in Python 2 (see Martin's answer ). filehandle.close does not necessarily flush.

Is there a way to check whether the processor cache has been flushed recently?

问题 On i386 linux. Preferably in c/(c/posix std libs)/proc if possible. If not is there any piece of assembly or third party library that can do this? Edit: I'm trying to develop test whether a kernel module clear a cache line or the whole proccesor(with wbinvd()). Program runs as root but I'd prefer to stay in user space if possible. 回答1: Cache coherent systems do their utmost to hide such things from you. I think you will have to observe it indirectly, either by using performance counting
