Link-time optimization in debian packages
Hi, I have currently the problem that I have to use large, computing intensive applications [1,2]. These are usually implemented in many source files. I used in the past pseudo c files which include all other c files [3]. Of course, this is a hack and don't work in many situation due to conflicting local symbols. I played around a little bit with GCC's LTO [4]. It is really impressive for this kind of applications. I had a size reduction and speed increase with the tested applications. Of course, it was just a small testset and not really scientific. Link time-optimization exchanges the meaning of flags slightly [5]. It is currently necessary to provide the optimization related flags from CFLAGS/CXXFLAGS also in LDFLAGS. Otherwise the LTO will not really to a optimization step. I already found some smaller problems related to weird asm usage in some pic library code [6], but I would doubt that this is a big show blocker and will be fixed soon(tm). My question is now whether there are already plans to use LTO in Debian packages, any big debian related studies, policies, release goals, ...? It could also be interesting for large projects like Iceweasel, LibreOffice, ... Maybe the KDE Debian Package maintainer have a reason why they don't use KDE4_ENABLE_FINAL --- which would also be an argument against LTO.

Bug#625646: [akregator] Click one article, it gets unread but the next one is displayed
Package: akregator Version: 4:4.4.11.1-1 Severity: normal Tags: patch Since the update to 4.6.2, with displaying only unread articles in akregator, clicking an unread article (regardless of the source) makes the article unread and disappearing (the article is still there in the "all article list"). The next article in the list is displayed instead of the one clicked. Changing to all articles makes the behavior go away. The clicked article gets downloaded and displayed as it should. Problem description is here: https://bugs.kde.org/show_bug.cgi?id=271149 Fix is available here: https://projects.kde.org/projects/kde/kdepim/repository/revisions/1380ce172e4f98ab433085721f0e8fddef4ba621 --- System information. --- Architecture: amd64 Kernel: Linux 2.6.38-2-amd64 Debian Release: wheezy/sid 500 unstablewww.debian-multimedia.org 500 unstableftp.debian.org 500 testing ftp.debian.org 1 experimentalwww.debian-multimedia.org 1 experimentalftp.debian.org --- Package information. --- Depends (Version) | Installed ===-+-=== kdebase-runtime | 4:4.6.2-1 libc6(>= 2.2.5) | 2.13-2 libgcc1(>= 1:4.1.1) | 1:4.6.0-6 libkcmutils4 (>= 4:4.6) | 4:4.6.2-1 libkde3support4 (>= 4:4.6) | 4:4.6.2-1 libkdecore5 (>= 4:4.6) | 4:4.6.2-1 libkdepim4 (= 4:4.4.11.1-1) | 4:4.4.11.1-1 libkdeui5(>= 4:4.6) | 4:4.6.2-1 libkhtml5(>= 4:4.6) | 4:4.6.2-1 libkio5 (>= 4:4.6) | 4:4.6.2-1 libknotifyconfig4(>= 4:4.6) | 4:4.6.2-1 libkontactinterface4 (>= 4:4.6) | 4:4.6.2-1 libkparts4 (>= 4:4.6) | 4:4.6.2-1 libkpimutils4(>= 4:4.6) | 4:4.6.2-1 libqt4-dbus(>= 4:4.5.3) | 4:4.7.2-4 libqt4-xml (>= 4:4.5.3) | 4:4.7.2-4 libqtcore4 (>= 4:4.7.0~beta2) | 4:4.7.2-4 libqtgui4 (>= 4:4.5.3) | 4:4.7.2-4 libstdc++6 (>= 4.4.0) | 4.6.0-6 libsyndication4 (>= 4:4.6) | 4:4.6.2-1 Package's Recommends field is empty.

Bug#606949: [kopete] kwallet timeout
tag 606949 + squeeze sid patch fixed-upstream
forwarded 606949 https://bugs.kde.org/226270
thanks
This was already fixed in kde in r1151086 [1]. I tested it using the attached
patch for the kdenetwork 4.4.5-2 package.
It is quite irritating that I usually cannot enter my password in kwallet
before kopete asks me directly for _all_ my instant messaging account related
passwords. This makes kwallet in combination with kopete unusable for me.
