Log4Net RollingFileAppender not flushing IO buffer with low volume log

由 走远了吗. 提交于 2019-12-04 22:49:17
I'm pondering on the same issue as HENRI COOK did . It's been reported as a bug on Apache Jira as far as we can tell from the short description. My problem in essence is that events are only logged when the application is shut down (even weeks after the event). That happens when logging volume is very low. I'm seeing this on a Windows Server 2008 R2. This prevents us from capturing and reacting to production errors. Now the appender is not a buffering one. By default it also calls Flush() on the underlying stream every time a message is appended. My question is WHY is it not flushing? And is

Lets say my php code is similar to below. . . $range = range(0, 5); foreach ($range as $times) { if (ob_get_level() == 0) ob_start(); for ($i = 0; $i<1; $i++){ echo "<br>example ".$times; echo str_pad('',4096)."\n"; ob_flush(); flush(); sleep(1.2); } ob_end_flush(); } What it displays is. . . example1 example2 example3 example4 example5 It waits a short period of time before showing the next line, I don't want to display all five at once, I want to replace example1 with the next one and so on for all five is this possible in php? any answers welcome You Would need to use javascript to replace

JSP Programming - response.getWriter().flush(); doesn't work

<% response.getWriter().write("Hello world<BR>\n"); response.getWriter().flush(); wait(10000); // 10 seconds response.getWriter().write("Goodbye happiness.<BR>\n"); %> Expected results: "Hello World" is displayed in the browser. 10 seconds later, "Goodbye happiness." is displayed. What happens: The page sits there loading for 10 seconds, and then "Hello World Goodbye Happiness" are displayed at the end. What I want to do is display the status of a long-running operation as different milestones are reached. Is this possible? I'm using Eclipse EE (with Tomcat) on Windows 7. <html> <body> You

How can I manually flush a boost log?

由 谁都会走 提交于 2019-12-04 10:24:15
I'm playing with Boost.Log in boost 1.54.0 to see if it is a viable option for my application. In general, I don't have a problem with the buffering, so I'm not looking to turn on auto_flush or anything... but I noticed that messages that are logged before I call fork() are duplicated, and I'm wondering if it's because they are buffered, the buffer gets duplicated when the process image is copied, and then both processes eventually write their buffer copies to the log file... So basically, I'd like to just do a manual flush on the log, one time only, immediately before I call fork() in order

Reading output from child process using python

由 房东的猫 提交于 2019-12-04 10:17:48
问题 The Context I am using the subprocess module to start a process from python. I want to be able to access the output (stdout, stderr) as soon as it is written/buffered. The solution must support Windows 7. I require a solution for Unix systems too but I suspect the Windows case is more difficult to solve. The solution should support Python 2.6. I am currently restricted to Python 2.6 but solutions using later versions of Python are still appreciated. The solution should not use third party

Do I need to do StreamWriter.flush()?

由 ╄→гoц情女王★ 提交于 2019-12-04 08:51:55
问题 Suppose this C# code: using (MemoryStream stream = new MemoryStream()) { StreamWriter normalWriter = new StreamWriter(stream); BinaryWriter binaryWriter = new BinaryWriter(stream); foreach(...) { binaryWriter.Write(number); normalWriter.WriteLine(name); //<~~ easier to reader afterward. } return MemoryStream.ToArray(); } My questions are: Do I need to use flush inside the loop to preserve order? Is returning MemoryStream.ToArray() legal? I using the using -block as a convention, I'm afraid it

Flushing log to disk, exception in VerifyOSHandlePosition

由 允我心安 提交于 2019-12-04 05:30:40
问题 How can I write a logfile from a C# service so that it gets flushed to disk in a timely fashion? Here's what I've tried. In logging code, I opened a file like this: var file = return File.Open(name, FileMode.Append, FileAccess.Write, FileShare.Read); var writer = new StreamWriter(file); and wrote to it like this: writer.WriteLine(msg); writer.Flush(); file.Flush(); However the log was not flushed to disk in a timely fashion. So I tried adding a 5-second timer that does this: [DllImport(

Grails. Id is null after calling save

由 血红的双手。 提交于 2019-12-04 05:09:32
I've already searched about this, but still cannot figure out what I'm doing wrong. After calling save() the domain object id is null . I've read it'll happen if there's a problem when saving the object, and that save(flush:true) should throw an error if that's the case, but it's not. Look at my code and the output: def pic = new Picture(title:'XX', path:"XXX") album.addToPictures(pic).save() if(pic.validate()) println "no errors. New id: " + pic.id else println "with errors" Output: no errors. New id: null And when using flush:true def pic = new Picture(title:'XX', path:"XXX") album

How to delete an instance of a class?

由 眉间皱痕 提交于 2019-12-04 04:31:58
问题 So, I have this project that creates multiple instances of a class, and list them. At some point, the instanced class is not needed anymore. How can I flush it ? So far, it doesn't happen, even when the class has nothing to do anymore (if it had been a single static class, the program would have shut down), it's still in my list, and its public variables are still available ... 回答1: You can have your instances raise an event (OnInactivated, say). The list class should add a handler for such

Flush a socket in Python

由 时间秒杀一切 提交于 2019-12-04 03:59:42
问题 Is there a way in python to flush a socket once a request has been sent and the information has been obtained correctly? I have a socket that is used to send different commands at different times, so I was just wondering if this was possible. Any help would be greatly appreciated. 回答1: In general no is the answer - you can't flush a TCP socket. All that is under the control of TCP.
