[fpc-pascal] D-Bus. Non blocking listening for signals
Hi, Month ago I posted a bug (http://bugs.freepascal.org/view.php?id=18117) Admin give me solution and feedback, but this solution doesn't work well and i think he don't read my last comment. So, maybe someone have this same problem. There is good demo for d-bus rewrited line by line from official C example. It works fine, but this is console demo. This demo listen for signals in main loop. In GUI application, this example blocks user interface. I received a solution to use Application.OnIdle event for check for signal. It works, but not detect all signals. If host send 10 this same signals, my application detect only 4-6. This problem raise after upgrade d-bus interface from 0.92 to 1.2.16 two months ago. Previously, I could use timers and threads for listening signals. Regard ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

For example, you'll have to move your mouse or hit the keyboard for the OnIdle event to be called. I don't know if this will affect talking to dbus (does it queue up the signals?).

I need this solution only for linux I had a quick look at the dbus functions. Perhaps you can use dbus_connection_set_wakeup_main_function to set up a function that wakes up your main loop (containing something like: g_main_context_wakeup(g_main_context_default) for gtk+). This will fire the OnIdle event where you can read the message. Another solution can be to launch a thread that executes a loop of dbus reads. You can then communicate back to the main thread.

Henry Wow, thanks! I read few examples in different programing languages, but nowhere was no mention of this procedure. Although this example doesn't work (or I am doing something wrong): dbus_connection_set_wakeup_main_function(conn, @g_main_context_wakeup, g_main_context_default, nil); But I declared my own procedure where I call checking for signals: procedure TestTest(data: Pointer); cdecl; begin Form1.CheckForMessage; end; dbus_connection_set_wakeup_main_function(conn, @TestTest, nil, nil); And it works perfect! :) . Thanks again. BTW: About your suggestion to use threads. I used threads before and it worked very long on my application. But it stopped after upgrade d-bus interface. That is why I post this problem Regards. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

This may not be a problem. The way you've done it is probably OK! Henry ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

I don't think i have a RAM problem.
I am running this on a

i can reproduce the error with this little programm.
The programm still prints the test1 and test2.
And when he tryes to set the var Application it crashed in Line47.
test svn2revisioninc.pas
program Svn2RevisionInc;
{$mode objfpc}{$H+}
uses

TSvn2RevisionApplication = class(TCustomApplication)

The admin (me) did see your comment but didn't find time yet to investigate the problem in great length :) However, it seems that Henry Vermaak gave you a solution. I am glad he did, because I have written a complete set of D-BUS components which I was about to publish, and they would suffer from the same problem when used in a GUI app. So now I know that I should create an integration with the Lazarus message loop.
