Please revert commit 77aed4a4 [Add nominal preventive maintenance in starttde]

by François Andriot

Hello, I've just found out some changes in the "starttde" script, see commit 77aed4a4 http://www.trinitydesktop.org/patches/1393268197:77aed4a4eba63e760c40cc5b3d… I do not agree with what that patch for 2 reasons: 1) The principe: on my computer, I'm using TDE both on local session and in remote session at the same time, using the same user account. So when I login remotely, this patch will probably kill my locally-opened session ... 2) The way it is written: there are several piped commands (why not using a single awk or simply use bash ?) and the code is not robust at all. What is my user is called "greppy" for example ? (ok this is unlikely, but not impossible). The "grep -v grep" will eliminate this line ... Please avoid using a full-featured "ps" output then trying to parse the output! The "ps" command can already filter on user (ps -u $USER) and select output format (ps -o field1,field2 ...) So, at very least, the command could look like : ps -u ${USER} -o pid,cmd h | while read pid command args; do case "${command##*/}" in "dcopserver"|"gam_server") kill $pid ;; esac done Another approach would be to parse the /proc/[0-9]*/ folders, to avoid using any "ps" command at all...

CMake - get list of ALL variables available to build (take the upper hand)

by David C. Rankin

All, I have always been frustrated by not knowing what variables were available to cmake so that I could intelligently adjust include_directories or target_link_libraries without pulling my hair out. I have stumbled on two very different and very useful ways of showing all cmake variables available to your build. They literally pull back the cmake veil of secrecy... Both are simple: (1) simply include the following code snippet in any CMakeLists.txt to dump all variables (both in-use & available) to stdout during the build (then just save the list to a text file): # dump all variable names get_cmake_property(_variableNames VARIABLES) foreach (_variableName ${_variableNames}) message(STATUS "${_variableName}=${${_variableName}}") endforeach() (2) simply call cmake with 'cmake -LAH' and it will do something similar, but not quite as complete. The outputs are this: (1) (from an old kde3 install) -- Could NOT find Threads (missing: Threads_FOUND) -- Found KDE3 include dir: /opt/kde3/include -- Found KDE3 library dir: /opt/kde3/lib64 -- Found KDE3 dcopidl preprocessor: /opt/kde3/bin/dcopidl -- Found KDE3 dcopidl2cpp preprocessor: /opt/kde3/bin/dcopidl2cpp -- Found KDE3 kconfig_compiler preprocessor: /opt/kde3/bin/kconfig_compiler -- CMAKE_AR=/usr/bin/ar -- CMAKE_BASE_NAME=g++ <snip> -- KDE3PREFIX=/opt/kde3 -- KDE3_BUILD_TESTS=OFF -- KDE3_DCOPIDL2CPP_EXECUTABLE=/opt/kde3/bin/dcopidl2cpp -- KDE3_DCOPIDL_EXECUTABLE=/opt/kde3/bin/dcopidl -- KDE3_DEFINITIONS=-DQT_CLEAN_NAMESPACE;-D_GNU_SOURCE;-D_XOPEN_SOURCE=500;-D_BSD_SOURCE -- KDE3_FOUND=TRUE -- KDE3_INCLUDE_DIR=/opt/kde3/include -- KDE3_INCLUDE_DIRS=/usr/lib/qt3/include;/opt/kde3/include -- KDE3_KCFGC_EXECUTABLE=/opt/kde3/bin/kconfig_compiler -- KDE3_KDECORE_LIBRARY=/opt/kde3/lib64/libkdecore.so -- KDE3_LIBTOOL_DIR=/lib64/kde3 -- KDE3_LIB_DIR=/opt/kde3/lib64 -- KDE3_MODULE_DIR=/usr/share/cmake/Modules -- KDECONFIG_EXECUTABLE=/opt/kde3/bin/kde-config -- PROJECT_BINARY_DIR=/home/david/dev/kde3/tutorial/p1bld -- PROJECT_NAME=p1 -- PROJECT_SOURCE_DIR=/home/david/dev/kde3/tutorial/p1 -- QGLOBAL_H=#define QT_VERSION_STR "3.3.8c" -- QT3_FOUND=TRUE -- QTVERSION_MOC= -- QTVERSION_UIC= -- QT_AND_KDECORE_LIBS=/usr/lib/qt3/lib64/libqassistantclient.a;/usr/lib/qt3/lib64/libqt-mt.so;/usr/lib64/libX11.so;/usr/lib64/libXext.so;dl;/opt/kde3/lib64/libkdecore.so -- QT_DEFINITIONS=-DQT_SHARED;-DQT_NO_DEBUG;-DQT_THREAD_SUPPORT;-D_REENTRANT -- QT_FOUND=TRUE -- QT_INCLUDE_DIR=/usr/lib/qt3/include -- QT_LIBRARIES=/usr/lib/qt3/lib64/libqassistantclient.a;/usr/lib/qt3/lib64/libqt-mt.so;/usr/lib64/libX11.so;/usr/lib64/libXext.so;dl -- QT_MOC_EXE=/usr/lib/qt3/bin/moc -- QT_MOC_EXECUTABLE=/usr/lib/qt3/bin/moc -- QT_MT_REQUIRED=TRUE -- QT_QASSISTANTCLIENT_LIBRARY=/usr/lib/qt3/lib64/libqassistantclient.a -- QT_QTMAIN_LIBRARY= -- QT_QT_LIBRARY=/usr/lib/qt3/lib64/libqt-mt.so -- QT_UIC_EXE=/usr/lib/qt3/bin/uic -- QT_UIC_EXECUTABLE=/usr/lib/qt3/bin/uic -- QT_VERSION_STRING=3.3.8c -- QT_WRAP_CPP=FALSE -- QT_WRAP_UI=FALSE (2) # cmake -LAH // Path to a program.

Notes to commit 77aed4a4

by Slávek Banko

Darrell, I have a note to commit 77aed4a4. I'm afraid that used grep is dangerous. For example, my colleague has a login name 's' (yes, only one letter). Such grep would return unwanted results. I propose a change roughly as follows. This will make it possible to omit some grep and also condition. ps -u $USER -o pid= -o comm= | grep -w kdesktop_lock | awk '{print $1}' | xargs -r kill -9 The second note is that this killing can be dangerous. If the machine is configured for multi-user login (multi-seat, xdmcp), the user could have multiple active sessions. Alternatively, user could have running some applications remotely - dcopserver would be active for remote session. -- Slavek

tdepowersave - continually grinding away 3.6%-6% of CPU -- confirm?

by David C. Rankin

Darrell, Slavek, All, On your R14 install, open a 'top' or 'htop' window and tell me what your 'tdepowersave' use is. By far -- tdepowersave is the top CPU user on my build continually taking more than any other process. This is not right. It is using 2x-3x more CPU than X or kded and is continually at the top of the list. It never stops. What do you see? -- David C. Rankin, J.D.,P.E.

Showfoto - thumbnails not generating?

by David C. Rankin

All, I was using showfoto earlier and noticed when you load images into the viewer to prepare for a slide-show, etc, none of the thumbnails for the images are generated. Is this something I'm doing wrong or is this a generic problem. Can someone please confirm. Thanks. Here is a screenshot of what I see: http://www.3111skyline.com/dl/dt/trinity/ss/showfoto-no-thumbs.jpg -- David C. Rankin, J.D.,P.E.

ktimer works fine, but crash on close

by David C. Rankin

All, ktimer works fine in all respects, but when I closed the app (top-left window-decoration control, rt-click -> close) ktimer crashed and produced the attached kcrash. Can somebody see if they see the same on their system. Thanks. -- David C. Rankin, J.D.,P.E.
