Why hibernate session.close() does not flushes the data automatically?

由 非 Y 不嫁゛ 提交于 2019-12-07 22:19:40
问题 When hibernate closes a session, the purpose of close is basically to close the underlying connection and the clean up the first level cache. Why the flush also does not happens automatically here? 回答1: From a transactional point of view, flushing is very different from closing the session and flush should occur inside the boundaries of a transaction (or at commit time): Ending a Session usually involves four distinct phases: flush the session commit the transaction close the session handle

Can I flush data implicitly?

问题 Is there a way to implicitly flush data to an output stream? #include <iostream> #include <fstream> using namespace std; #define log logstream int main() { ofstream logstream("test.log"); log << "Test1" << 123 << endl; // explicitly flushed log << "Test2" << 123; // ? // Test2 not written, yet... cout << "Check log file..." << endl; int tmp; cin >> tmp; } I would like to be able to log without specifying the << endl manipulator every time. 回答1: You may use std::unitbuf. log << std::unitbuf;

Flush output in for loop in Jupyter notebook

由 [亡魂溺海] 提交于 2019-12-07 03:55:56
问题 I want to print out i in my iteration on Jupyter notebook and flush it out. After the next iteration, I'll print the next i . I tried solutions from this question and this question, however, it just print out 0123...9 without flushing the output for me. Here is my working code: import sys import time for i in range(10): sys.stdout.write(str(i)) # or print(i, flush=True) ? time.sleep(0.5) sys.stdout.flush() these are my setup: ipython 5.1, python 3.6. Maybe, I missed something in the previous

flush mode changed in grails from AUTO to MANUAL

由 不打扰是莪最后的温柔 提交于 2019-12-07 01:06:13
问题 After upgrading my Grails project from 1.3.7 to 2.4.0 and after fixing various issues related to the new grails version, I realized that none of the changes done to any object would be persisted anymore (at all) except if save(flush:true) is called. With Grails 1.3.7 the default behavior when saving a domain instance using save() is that changes get persisted automatically, due to hibernate flushMode => FlushMode.AUTO . In Grails 2.4.0 this is not true anymore. The default flushMode of the

Calls to flush cout are ineffective

问题 I am attempting to have the cout buffer flush to view a string before I manipulate it. Ive attempted to flush the buffer with calls to both std::flush() and std::cout.flush() but neither actually flush my output. Only a call to std::endl has successfully flushed the buffer for me. Here is my code std::istringstream stm (game.date()); int day, month, year; char delim = '/'; std::cout << "Date before: " << game.date() << std::flush; // first flush attempt std::cout.flush(); // second flush

How do I “flush” a TCP Client Buffer?

由 强颜欢笑 提交于 2019-12-06 22:07:41
I've pulled from several examples to setup a Full Duplex C# TCP Client connected to a server. The basic concept is that the client and server both send/receive messages (commands and events). Therefore, I've developed a FullDuplexSocket class that exposes a Send method to send messages to the server and a event handler to receive messages from the server. Everything works except I can't seem to flush the buffer of messages received from the server. Each time the server sends a new message, the buffer in my socket contains all the old messages (already read) and the new message(s). I could

Log4Net RollingFileAppender not flushing IO buffer with low volume log

由 拈花ヽ惹草 提交于 2019-12-06 17:12:34
问题 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

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

问题 <% 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

Is a PrintWriter a BufferedWriter

由 大城市里の小女人 提交于 2019-12-06 07:42:12
Basically I would like to know whether or not the PrintWriter is a Buffered Writer. I have seen code like PrintWriter pw = new PrintWriter(new BufferedWriter(new FileWriter(file))); However from this javadoc : Parameters: file - The file to use as the destination of this writer. If the file exists then it will be truncated to zero size; otherwise, a new file will be created. The output will be written to the file and is buffered. Bottom line: I think that PrintWriter is buffered since the javadoc "kind of mention it" (see the quote) and if I don't flush a PrintWriter it does not get printed.

How can I manually flush a boost log?

由 ぐ巨炮叔叔 提交于 2019-12-06 04:13:03
问题 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
