In case of difficulties to write a C program for the displaying the icon, trapping the D-Bus calls and launching the right python program, why not porting the whole applet in C ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/584175 Title: the applet is wasting memory -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 584175] Re: the applet is wasting memory
Jerome: The point is that in the case where there are no print jobs and no printers (and therefore no icon), it would just be a case of having a simple C program. There could be a D-Bus method to invoke the jobviewer icon program (running as Python for the first time that session) when there are jobs or state-reasons, and this would be fairly easy to code up. It would be a fair amount more work to have the icon running entirely in C (the application would need to maintain state and examine IPP attributes; i.e. it would now need to link to libcups whereas previously it wouldn't), but maybe that's the way to go. It would be nice to at least have a proof of concept along with some numbers showing exactly how much less memory it uses in various different cases. Watch out though: it's not just signals from cupsd that cause the applet to do things, but also signals from system-config-printer-udev about there being new printers. What I'm saying is that the right way to do it is with D-Bus calls, and that it isn't just trivial. -- the applet is wasting memory https://bugs.launchpad.net/bugs/584175 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 584175] Re: the applet is wasting memory
I don't know well the underlying but it seems that it would consume 8 MB of additionnal memory even if python is running in an other process: 15 MB of physical memory made of 7 shared (with other instances of python ?) and 8 MB specific to the applet. -- the applet is wasting memory https://bugs.launchpad.net/bugs/584175 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 584175] Re: the applet is wasting memory
Till, this is more of a problem for Ubuntu than it is for Fedora, as Fedora already has Python running elsewhere. It would be great if you could get a proof of concept going for this. The C program could be a fairly simple D-Bus application, listening for signals from CUPS and then invoking methods on session-activated D-Bus objects provided by system-config-printer (see e.g. newprinter.py's __main__ part in the master branch for an example of how that works). I'm afraid I don't have the time to look at it right now. -- the applet is wasting memory https://bugs.launchpad.net/bugs/584175 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 584175] Re: the applet is wasting memory
Tim, this would have the same solution as the login speed issue with the applet. We need a stub written in C here which calls Python programs like the job viewer or the new printer wizard if needed. -- the applet is wasting memory https://bugs.launchpad.net/bugs/584175 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here.

Shared memory is ~7MB.
