We know that the mysqld process has indeed *not* gone away, and re-opening the connection works. My theory is that the initial QSqlDatabase::open() creates a connection to the SQL server that is kept open permanently by the QSqlDatabase instance that Qt keeps internally (in the ConnectionDict) that references the same connection. The SQL server eventually closes the connection after some timeout, which the application doesn't notice until it tries to use the connection again. I've seen the same behavior from the python mysql drivers, so I think this is probably the correct explanation. I don't know if the mysql library offers a way to detect when you get disconnected that could be used to make the implementation reconnect automatically.

We know that the mysqld process has indeed *not* gone away, and re-opening the connection works. Ok, this appears to be caused by the wait_timeout option of the MySQL server[1], which defaults to 8 hours. If you are unwilling/unable to change the server config, there are at least two ways of working around this: 1) Setting the reconnect option on the mysql connection. Unfortunately, this is not supported by the Qt-API (not even QSqlDatabase::setConnectOptions) and requires fetching the raw MYSQL* handle from the QSqlDriver and using mysql_options() from libmysqlclient. 2) Since the wait_timeout is an *idle* timeout, the connection can presumably be kept alive by making regular dummy queries.

Re: [Interest] Long running application with database connection
In a similar situation, if I recall correctly, we elected to open the database connection each time we needed it. Through testing we found that connection pooling in the the underlying infrastructure (windows, using oracle and ms sqlserver) worked well. The reconnection cost was usually trivial compared with the actual query especially if the connection was recently used; the resulting code was simpler/cleaner; and the approach seemed robust to lots of other reasons (not just idle time) that the connection might drop. I do recall that it was hard to test well. Sam ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
[Interest] QTcpServer. Connecting.Sending data.
Hello,
here's the code of the redefined method run() of QThread class =
void run() override
{
srv = new (std::nothrow) tcp_server(ised_win_raw_ptr);
#ifdef DEBUG
qDebug() listener's thread = thread();
#endif
terminate_ = false;
while ( !terminate_ ) if ( !srv-isListening() )
srv-listen(QHostAddress::Any, port);
#ifdef DEBUG
qDebug() Deleting the ised_tcp_server object.;
#endif
srv-close(); // Closes the server. The server will no longer
listen for incoming connections.
delete srv;
}
The program connects to 9000 port for listening.
Using the netcat command
nc -vv 127.0.0.1 9000
yields
PC_NAME [127.0.0.1] 9000 (?) open
Then I typed start and hit Enter.
The break point has been set in incomingConnection which is redefined
in the tcp_server class inheriting QTcpServer.
Debugger did not paused in the method body when netcat connected to the port.
Solutions?

Hi,

I thought something as simple as:
** **
Behavior on Layout.preferredWidth {
NumberAnimation { duration: 1000 }
}
** **
would do.. Apparently not since it crashes qmlscene..
Do i need to do it differently or did i just hit a bug?

Version details:
Qt 5.1.0 x64 (i know, 5.1.1 is out)
Mac Mountain Lion fully updated

Hi Jan,
What i try to do is animate the (in this case) width. In a simple
description that would be it.
However, i try to animate the with of a component that is within a
Layout. In this case a RowLayout. If i use the width, the RowLayout itself
doesn't update, you can see that in this snippet [1]. Just press the nice
orange square :) What i want for that is to work. I tried animating the
Layout.preferredWidth property because changing the width using that does
update the RowLayout, but then the animation doesn't work.
That's all i'm trying to do.
[1] http://pastebin.kde.org/pxgjxhtza
Another bump.
I haven't figured out a way to make this animated.
Added Jens to the CC. Hopefully he knows a way for this.

Re: [Interest] QTcpServer. Connecting.Sending data.
Hi Alexander,
QTcpServer.listen only sets up the listening - it does not wait until a new
connection arrives. In my code, I only call listen once, then run an event
loop. The new connections arrive in the incomingConnection slot.
void MyThread::run()
{
srv = new (std::nothrow) tcp_server(ised_win_raw_ptr);
if (!connect(srv,SIGNAL(newConnection(),srv,SLOT(connection())
)) error
if (!srv-listen(QHostAddress::Any, port)) error
exec();
srv-close();
delete srv;
}
Of course, you can put the slot anywhere. The slot uses
nextPendingConnection() to get the socket.
Works well for me.
If you cannot use QThread.exec, then use srv-waitForNewConnection in your
terminate loop.
