How to stop network operation?

[newtolinux]

Hi...
I am sending a large file over a network by using QNetworkAccessmanager's post method

QNetworkReply *reply = manager->post(request, postDataByteArray);

QNetworkReply *reply = manager->post(request, postDataByteArray);

To copy to clipboard, switch view to plain text mode 

reply finished signal will be emitted once the entire post operation is complete. untle that networkaccessmanager keeps on sending the my large file.
But my question is can i interrupt that post operation in middle if i want. I could not find any proper apis in networkaccessmanager's documentation to achieve that.
Can some one suggest me how to solve this problem?

QNetworkReply has a method abort(). However, at least with Qt 4.6 there is a bug, which make this unusable. I don't remember what exactly the problem was, but there was already a bug report. This is what I noted in my source code:

// TODO/FIXME: This is a memory leak since the QNetworkReply might not be deleted.
// However, there is a bug in Qt 4.6.3 and 4.7.0 which results frequently in a segfault
// when calling abort or trying to delete the reply before it signals finished on its own.
m_queryReply = NULL;

// TODO/FIXME: This is a memory leak since the QNetworkReply might not be deleted.
// However, there is a bug in Qt 4.6.3 and 4.7.0 which results frequently in a segfault
// when calling abort or trying to delete the reply before it signals finished on its own.
m_queryReply = NULL;

To copy to clipboard, switch view to plain text mode 

So my "solution" for this is just to ignore the reply result if it should arrive later.

The bug report said the problem would be fixed in 4.7.x However, I did not tried yet with 4.7.1.
