问题 FlushMode in both Sessions is set to AUTO. Session A : Session begins Session B : Session begins Session A : Session creates new objects, Session#flush() is called, Session ends. Session B : Session reads objects from database and Session#flush() is automatically performed before this operation. Will the newly created objects of Session A also be visible to Session B ? 回答1: It depends on your isolation level and the underlying database. Hibernate defaults the isolation level to the underlying

问题 How do I force Python's print function to output to the screen? This is not a duplicate of Disable output buffering - the linked question is attempting unbuffered output, while this is more general. The top answers in that question are too powerful or involved for this one (they're not good answers for this), and this question can be found on Google by a relative newbie. 回答1: On Python 3, print can take an optional flush argument print("Hello world!", flush=True) On Python 2 you'll have to do

PHP flush information in controller

☆樱花仙子☆ 提交于 2019-12-11 12:56:07
问题 I am trying to send data to view from controller in PHP CodeIgniter. I am calling the PHP function through ajax and using ob_flush to send data back but the problem is that all the flush calls are concatenated in later calls. For example: the first flush send 1 second flush call send 12 instead of 2 . This is my controller loop. foreach ($csv_array as $row) { ob_start(); $varint=$varint+1; echo $varint; $content = ob_get_contents(); ob_end_clean(); echo $content; ob_flush(); flush(); while

问题 I have a C++ program that is writing to a file on Windows 7. When I call f.flush() the NTFS file does not get bigger. Is there any way to force the file to get flushed? 回答1: You can look here: How do I get the file HANDLE from the fopen FILE structure? the code looks like this: FlushFileBuffers((HANDLE) _fileno(_file)); do not forget call fflush(file), before call FlusFileBuffers. For std::fstream and gnu stl, I checked it on my linux box, have no windows at home, but should work with mingw,

How to flush pipes to clean the buffer in C, when both pipes are part of same process?

问题 In a X function, I am using pipes, to buffer(couple of printfs , which are printed in Y function called inside from X function) the stdout stream if one Fd and then after buffer is complete,close one pipe and other Fd and then use printf on it. I want to be completely sure that buffer is empty, when next time this X function is called again to do the task. I tried couple of things which I found online: fflush ioctl , _flushlbf : looks like they aren't supported by gcc. Does g++ support it?

PHP send SOAP response early?

北城以北 提交于 2019-12-11 07:37:31
问题 Well this is an old issue I've been dealing with and still no solution, so trying a new approach. How can I send th SOAP response early (Before script execution ends)? These issues are cause when the ACK file is not sent before 30 seconds as the process takes longer to complete then the allotted time. flush() not working, get this error: org.xml.sax.SAXParseException: XML document structures must start and end within the same entity. without the flush() I get this org.xml.sax

You can see the output from his repo it

Is object.__del__(self) the most appropriate place to flush a logging class?

一个人想着一个人 提交于 2019-12-11 06:25:14
问题 I have a custom logging class for my Python script with a flush() method which print() s the contents of a list. I would like to include flush() in the special __del__() method in case the program ends without the log being flushed. However a note in the documentation states: [...] when del () is invoked in response to a module being deleted (e.g., when execution of the program is done), other globals referenced by the del () method may already have been deleted or in the process of being

Java WebSocket server OutputStream not flushing

问题 I have read a similar question, but my problem wasn't solved. I am trying, for the sake of learning, to build my own Java WebSocket server. The server is set up fine, it accepts incoming connections and gets the handshake data from the client. My server then calculates the handshake return data and tries to write it and flush it. Nonetheless, the in the web inspector, no response headers are shown for the client and the onopen -JavaScript event is never fired. String EOL = System.getProperty(

ZF2 Doctrine: When to flush ObjectManager

China☆狼群 提交于 2019-12-11 04:06:51
问题 when is the best "time" to flush the Entity/Object-manager? Should it be after every persist operation? Or should it be run once on e.g. postDispatch? 回答1: Running it after every persist is an antipattern actually. Ideally, you should run it once at the end of the request. I would not put it in a postDispatch handler, because that means it will run after every request, and that is going to be costly performance wise on, for example, list pages, where you list entities with many relations,
