Preparation for work on translations
by Slávek Banko 01 Mar '19

01 Mar '19

Hi all, those of you who have been here for a long time might recall that when I joined the community I assumed that my tasks would be only two: backport patches to the stable TDE series and work on translation. Over time, it turned out that my tasks on the project would be bigger. However, work on translations is still a postponed task. Recently, I have devoted some time to the tasks that are essential to move us forward with the work on translations. Therefore, I would like to inform you about the results and related plans. I apologize for long email. 1. Unnecessary updates of POT files during package build I observed that during the DEB packages build, an attempt was made to update POT files. However, this step makes no sense. Bundling usually takes place in dedicated pure chroot. Therefore, the result of updating POT files would be discarded anyway. So this is unnecessary work. At the same time, the extractrc tool is used during the POT files update. But this tool is part of the tdesdk-scripts-trinity package. Therefore, when building other packages, it is usually not present. So updating POT files during building could not work well. That's why I already removed these unnecessary updates of POT files while building DEB packages. 2. Do we still need to use the old modified version of xgettext? I found out what the current status is and whether there are still reasons to use the old modified version of xgettext (kde-xgettext). Patches for the old version solve two things: a) adding a way to enter plural forms of strings b) adding a way to enter translation context The current versions of gexttext already have both of these options, but they seem to be implemented in a different way. Before we can start using standard xgettext in TDE, we will need to add support for a new way of plural forms of strings and translation contexts. So far, we need to continue using an old modified version of kde-xgettext. 3. Can modern gettext replace the extractrc tool? Modern versions of gettext can handle XML files. We use XML files for 'kcfg', 'rc' and 'ui'. Using ITS support in gettext, there is a way to define which texts are to be extracted for translations. I tested this option, but I encountered some problems: a) Tags are written in strings as html entities: < / > / &. After extraction using xgettext, are left in this form. But the extractrc tool convert them to the appropriate characters '<', '>', '&'. I did not find a way to do this with xgettext and ITS. b) XPath is used to determine which strings are to be extracted from XML files. Files 'kcfg' use their own XML namespace and I did not find a way how to enter XPath to work properly with ITS in xgettext. That's why I decided it was better to continue using the extractrc tool. 4. How do we create and update POT files? In order to provide strings for translation, we first need to create and update POT files. The best place for these files is right in the source code – in GIT. Therefore, these files need to be maintained independently of the building binaries. Therefore, it is obvious that for this task it is not a good time during the build binary packages, nor the usual use of Automake or CMake. Although the usual use of CMake with CMakeLists.txt for updating POT files is not a good choice, using CMake as such seems to be a good idea. CMake allows using the -P option to process a different file than the usual CMakeLists.txt. In this case, it does not create build folder, it does not create a cache - exactly as it suits us for our purpose. I decided to use the name CMakeL10n.txt. I have prepared the CMake module TDEL10n.cmake. This module provides functions for simplifing directories handling – function tde_add_l10n_subdirectory as the equivalent for add_subdirectory and function tde_auto_add_l10n_subdirectories as an equivalent for tde_auto_add_subdirectories. And above all, the tde_create_l10n_template macro that provides POT files generation. This macro provides some benefits that seemed useful: a) If resource files are processed – for example, *.ui, the work file "rc.cpp" is commonly used to save extracted strings for translation. This file is then processed by kde-xgettext. Links to the original location of strings in the resulting POT file then refer to this "rc.cpp", which is not very useful. The tde_create_l10n_template macro performs additional processing by replacing references to "rc.cpp" with references to the original resource files. Therefore, the POT file does not refer to a non-existent "rc.cpp" file, but to real locations in resource files. b) When a new POT file is generated, a comparison is made with the original POT file. If only the date of POT file generation is changed, the original POT file will be left unchanged. This prevents unnecessary POT file updates. This will allow to run a regular update of POT files without causing unnecessary commits. 5. What's next? For revisions and comments, I created a pull request containing a CMake module TDEL10n.cmake: https://mirror.git.trinitydesktop.org/gitea/TDE/tde-common-cmake/pulls/2 ...and pull requests with a demonstration of use CMakeL10n in two modules: https://mirror.git.trinitydesktop.org/gitea/TDE/abakus/pulls/1 https://mirror.git.trinitydesktop.org/gitea/TDE/tdebase/pulls/19 After testing, we will need to add CMakeL10n.txt to generate POT files in all other modules. Once we have automated updating of POT files, translation work can begin! 6. How can users work on translations? I will leave the answer to this question for later. Whoever was more attentive could have noticed in several earlier commits that "something is being prepared" :) Cheers -- Slávek

TDM grey-screen-of-death. Can anyone point me in the right direction?
by Russell Brown 21 Feb '19

21 Feb '19

Hi Devs, Before I file a bug on this I'd like to try to narrow it down a bit so I'm looking for some pointers on how TDM works and where I might start looking. Since upgrading to Debian Stretch and TDE: R14.0.6, we're seeing an issue where TDM won't start a new session for a display and has zombie child process(es). This is with networked X-Terminals using XDMCP. It's happening roughly every week or so (no fixed time of day) on a system with around 30 users/terminals logging in and out. It might happen after a user logs out or after the remote terminal is reset or, according users rumour, after a kdesktoplock has been unlocked; I'm failing to get real concrete info on that aspect (I'm sure you know what users are like!). Anyway, the terminal gets fired up/restarts X11 after a logout but doesn't then get a response to its XDMCP requests and just sits there showing a default X11 background (hence the grey-screen-of-death moniker). When TDM is in this state, doing "ps waux | grep tdm" shows: root 18481 0.0 0.0 0 0 ? Z Feb19 0:00 [tdm] <defunct> root 20178 0.0 0.0 0 0 ? Z Feb19 0:00 [tdm] <defunct> root 25478 0.0 0.0 0 0 ? Z Feb19 0:00 [edm] <defunct> These processes in pstree look like: |-tdm(12251)-+-tdm(1004)---tdm_greet(1005)-+-krootimage(1009) | | |-twin(1013) | | `-{tdm_greet}(1020) | |-tdm(1389)---tdm_greet(1390)-+-krootimage(1392) | | `-{tdm_greet}(2309) <snip> | |-tdm(4546)---tdm_greet(4547)-+-krootimage(4549) | | |-twin(4552) | | `-{tdm_greet}(4556) | |-tdm(4738)---starttde(21417)-+-ssh-agent(21539) | | `-tdeinit_phase1(21613)---kwrapper(21614) | |-tdm(18481) | |-tdm(20178) | |-tdm(20178) | |-tdm(25478) <snip> |-tdmtsak(15721) Doing an strace on the main TDM process, shows it doing a select on a bunch of fds but nothing else. If I restart tdm (/etc/init.d/tdm restart), it will start working again and, mostly, preserve the live users sessions... but sometimes not and everyone gets booted out :-( Once restarted like this, some tdms have a parent of systemd and some are children of the new? main tdm process: systemd(1)-+-ModemManager(1591)-+-{gdbus}(1599) | `-{gmain}(1595) <snip> |-tdm(16655)---starttde(6171)-+-ssh-agent(6293) | `-tdeinit_phase1(6369)---kwrapper(6370) |-tdm(29430)---starttde(26723)-+-ssh-agent(26845) | `-tdeinit_phase1(26933)---kwrapper(26934) |-tdm(32506)---starttde(21854)-+-ssh-agent(21976) | `-tdeinit_phase1(22057)---kwrapper(22058) |-tdm(32680)-+-tdm(424)---tdm_greet(429)-+-krootimage(1068) | | |-twin(1071) | | `-{tdm_greet}(1075) | |-tdm(426)---starttde(7968)-+-ssh-agent(8092) | | `-tdeinit_phase1(8229)---kwrapper(8231) | |-tdm(428)---tdm_greet(431)-+-krootimage(1150) | | |-twin(1155) So... can anyone suggest where I should be looking to try an narrow down the cause of this? How does TDM know when a session ends and what stops it providing a new one? Should it have zombies hanging around? Should it reap it's zombie children? I see there's a ReapChildren function in dm.c which seems like it should get called when it gets a SIGCHLD. How could that not be working?

Is there a way to make reboots following updates not take over 2 minutes just to begin? I see this somewhat often, but haven't been tracking with which versions. The one just done is 14.0.6~pre38 on Buster. What exactly is a "User Manager"? -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!

Bug 2998
by Russell Brown 11 Feb '19

Hi, I don't know how closely the devs watch the Bug list but I believe I've fixed Bug 2998. As this bug results in kdesktop/kdesktop_lock eating CPU and going unresponsive; might I humbly request that the fix is incorporated in the next possible/dev version. As the code I posted on bugzilla used a crude fixed buffer, here's a cleaned up version that uses malloc. *** /tmp/tdebase-trinity-14.0.6~pre38/kdesktop/lock/main.cc Thu Feb 7 15:48:21 2019 --- /usr/tmp/tdebase-trinity-14.0.6~pre38/kdesktop/lock/main.cc Sun May 20 19:41:55 2018 *************** *** 325,336 **** #endif } ! char *locknameroot="kdesktop_lock_lockfile."; ! char *lockfilename = (char*)malloc(strlen(locknameroot) + strlen(getenv("DISPLAY")) + 1); ! strcpy(lockfilename,locknameroot); ! strcat(lockfilename,getenv("DISPLAY")); ! !

Installing from scratch on Debian Stretch from freshly build repository
by deloptes 11 Feb '19

11 Feb '19

Hi, I see this as beta testing exercise, so here is what I did: 1. Long time ago I asked Michele to help me build local repository and build system. This now works and I can build the packages from git repository, which I checked out. 2. I then create a local repository and can use it from the local network 3. I had no problem installing, upgrading and testing - it is just great! I just wanted to try installing TDE from scratch in clean chrooted debootstrap from the repository I build last month, but I failed on few metapackages. (This is perhaps related to a UL issue discussed few days ago) apt-get install tde-trinity The following packages have unmet dependencies: tde-trinity : Depends: tde-core-trinity (>= 4:14.0.0~) but it is not going to be installed Depends: desktop-base-trinity but it is not installable E: Unable to correct problems, you have held broken packages. Why I don't find desktop-base-trinity in stretch $ grep desktop-base-trinity -r tde/1_git/tde-packaging/debian/stretch/ | grep Package but it is in $ grep desktop-base -r tde/1_git/tde-packaging/ | grep Package tde/1_git/tde-packaging/ubuntu/maverick/defaultsettings/desktop-base/debian/control:Package: desktop-base-trinity same for tde-core $ grep tde-core -r tde/1_git/tde-packaging/ | grep Package tde/1_git/tde-packaging/debian/squeeze/metapackages/meta-tde/debian/control:Package: tde-core-trinity tde/1_git/tde-packaging/debian/lenny/metapackages/meta-tde/debian/control:Package: tde-core-trinity Where do I log this bugzilla or gitea? thanks

tdevelop & libtool error: a dirty solution
by Dr. Nikolaus Klepp 03 Feb '19

03 Feb '19

Hi all! Hope this helps others that try to get started with tdevelop: As written some time ago I was not able to build any project with tdevelop due to a mismatch of "libtool": The one that is created ftom tdevelop does not match the one that is needed for devuan. I just found out, that is sufficient to replace "libtool" (that one that is created by configure) with a symlink to the installed libtool and the the project compiles perfect. Now this is a dirty hack to get things working for all tde projects that are created by tdevelop: cd /opt/trinity/share/apps/kdevappwizard/template-common tar xzf admin.tar.gz cat << XXX >> admin/configure.in.bot.end rm libtool ln -s $(which libtool) . XXX tar czf admin.tar.gz admin rm -R admin Now there is another "configure.in.bot.end" template for kde which is most likely to suffer from the same problem, but as I am not interested in kde I did not check.

[trinity-devel] schizoid greeter window on dual display setup
by Felix Miata 16 Jan '19

16 Jan '19

I do a lot of mix and match with displays and PCs. The one I have now booted to Sid has 2560x1440 and 2560x1080 displays on an old ATI dual DisplayPort PCIe card. I have the larger configured as primary and the smaller as upper via an xrandr script in /etc/X11/Xsession.d/. 14.0.6dev's first greeter appearance after booting is on the upper/smaller display, but moves to the lower/larger display on logging out. I'd rather it always be on the larger. Is this something configurable? If so, where & how? Is this something worth or needing a bug report? -- Evolution as taught in public schools is religion, not science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!
