[arch-general] Script for finding and "moving" older duplicate packages from /var/cache/pacman/pkg
by David C. Rankin 26 Aug '09

26 Aug '09

Listmates, I like to keep the current set of updated packages in /var/cache/pacman/pkg but not have all of the older duplicates in there as well. However, I don't want to delete the old packages either, in case I need to downgrade a package. I simply want to move the older packages to a backup location on a different partition so I'm not filling up / with several extra gigabytes of older packages. To do this I adapted a script that I used to clean duplicates from my local rpm repository and changed the script to deal with package-name-v.e.r-arch.pkg.tar.gz instead of rpm-name-v.e.r-s.u.b-arch.rpm. (Thankfully arch just uses the pkg directory instead of a nested spiderweb under /var/cache/zypp/packages/.....) The script for finding and moving older duplicate packages is named fduppkg and is fairly self-explanitory. Running without arguments gives the options: 23:33 supersff:~/scripts/file> fduppkg Usage: <search dir> [ -d -l logfile -s -v ] Searches <search dir> for duplicate pkgs and moves duplicate files to [dup_dir] or <search dir>/duplicates by default. -d | --dupdir Used to specify directory to hold duplicate rpms -l | --logfile Specify the log file name (default ./duplicates.log) -s | --silent Don't output anything to stdout, just log results -v | --verbose Output information showing which files are kept and not moved You should note that the actual check for older/newer uses the file modification date to make the decision rather than parsing the version number digit-by-digit. So if you have done something nutty like moving all the packages out of /var/cache and then copying them back so all the file modification times are the same, this script won't work. (I could see it happening) If you have a need for something like this, you can grab the script at: http://www.3111skyline.com/download/Archlinux/scripts/fduppkg Since the script if fairly generic for packages, if you have a number of directories you want to operate on, you can just call the script from another script that sets the command line inputs. Example: http://www.3111skyline.com/download/Archlinux/scripts/fdup-archpkg I generally just create a link to the script in /usr/local/bin so it is in the search path. Also, if you just want to tear it apart for the bash scripting learning, I have commented it so it is somewhat readable. Enjoy. -- David C. Rankin, J.D.,P.E.

[arch-general] What changed: udev PolicyKit - No mount of usb or CD for non-root?
by David C. Rankin 26 Aug '09

26 Aug '09

Listmates, After updates this past week or so (not sure exactly when), Arch no longer mounts usb or CD/DVDs when inserted. What is the most likely culprit? -- David C. Rankin, J.D.,P.E.

[arch-general] bluetooth pairing with cellphone
by Dieter Plaetinck 25 Aug '09

25 Aug '09

hey dudes. I fail (sort of) at pairing my pc with my phone via bluetooth. (sony ericsson k810i, pc uses broadcom dongle) I have a system where everything is up to date, bluez is installed etc. the configs are all pretty much default. I did need to enable HID2HCI_ENABLE="true" in /etc/conf.d/bluetooth otherwise the bluetoothd daemon would abort immediately after startup ( ? ) I can do `hcitool scan` and see my phone. But to pair... 1) the bluez-simple-agent way: I start `sudo bluez-simple-agent`,it listens, and on the phone I search new devices. phone cannot find pc :( 2) the blueman way: 2a ) If I run as regular user, I get: dieter@dieter-ws-a7n8x-arch ~ blueman-manager Loading configuration plugins _________ on_bluez_name_owner_changed (/usr/bin/blueman-manager:99) org.bluez owner changed to :1.6 Using gconf config backend _________ SetAdapter (/usr/lib/python2.6/site-packages/blueman/gui/DeviceList.py:293) None ERROR:dbus.proxies:Introspect error on org.bluez:/: dbus.exceptions.DBusException: org.freedesktop.DBus.Error.AccessDenied: Rejected send message, 2 matched rules; type="method_call", sender=":1.33" (uid=1000 pid=5982 comm="/usr/bin/python /usr/bin/blueman-manager ") interface="org.freedesktop.DBus.Introspectable" member="Introspect" error name="(unset)" requested_reply=0 destination="org.bluez" (uid=0 pid=4642 comm="/usr/sbin/bluetoothd ")) Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/dbus/connection.py", line 578, in msg_reply_handler reply_handler(*message.get_args_list(**get_args_opts)) File "/usr/bin/blueman-manager", line 148, in on_bluez_name_owner_changed self.List = ManagerDeviceList(adapter=self.Config.props.last_adapter, inst=self) File "/usr/lib/python2.6/site-packages/blueman/gui/manager/ManagerDeviceList.py", line 71, in __init__ DeviceList.__init__(self, adapter, data) File "/usr/lib/python2.6/site-packages/blueman/gui/DeviceList.py", line 120, in __init__ self.SetAdapter(adapter) File "/usr/lib/python2.6/site-packages/blueman/gui/DeviceList.py", line 324, in SetAdapter except dbus.DBusServiceUnknownError: AttributeError: 'module' object has no attribute 'DBusServiceUnknownError' do i need to be in some kind of group or something? There was no post install message, nor info about this on the wiki page (http://wiki.archlinux.org/index.php/Bluetooth) 2b) if I run blueman-manager as root I can pair (hooray). But actually I don't want to run stuff as root, nor do I want to use the bloatware that is blueman-manager. Dieter

[arch-general] Stuff in /etc/cron.d/ won' work?
by Sven-Hendrik Haase 25 Aug '09

25 Aug '09

Hey there, I just noticed that I just couldn't get cron to properly execute stuff in /etc/cron.d/ no matter what I did. Let's say I have /etc/cron.d/lol with this content: * * * * * root echo "lol" >> /tmp/omg and restart crond afterwards, the crond log tells me that cron actually runs this command every minute without a problem. Sadly, this isn't the case and the file at /tmp/omg is created but remains without contents. In contrast, if I put an executable script to /etc/cron.hourly/lol with the content: echo "lol" >> /tmp/omg then the file at /tmp/omg fills up with lots of "lol"s after a couple of hours. It also works fine if I put it into the crontab. Now, I'd like to be able to use /etc/cron.d/ as well because it seems more transparent to me. Is there anything I do inherently wrong? -- Sven-Hendrik

[arch-general] Ocaml - missing md5 checksum
by vratil 24 Aug '09

24 Aug '09

Hi, I was trying to build ocaml package from source and since makepkg insists on presence of md5sums, I noticed that ocaml PKGBUILD is missing them. I'd fill a bug, but I'd forget about it before our bugzilla is launched again :-) Cheers Dan V.

[arch-general] GStreamer packages
by Thijs Vermeir 24 Aug '09

24 Aug '09

Hello all, I see that some GStreamer packages have been outdated, attached you can find the PGKBUILD's with upgraded version and some other modifications detailed below. (Coudn't find if this is already discused) I also had a question about the gst-plugins-base/good/bad/ugly packages. I see that they are now split-up in 2 packages (ex: gstreamer0.10-base and gstreamer0.10-base-plugins). The second one contains the plugins depending on external libraries and the first one contains libraries and plugins without external dependencies. Typically a user has all gstreamer plugins installed, or at least he is using some plugins from every package. So I propose that we also merge these 2 plugins to make it easier to maintain and match upstream packages. Does this sound logic or do I miss something? Changes to PKGBUILD: gstreamer0-10: 0.10.24 - disable tests and examples gstreamer0.10-base and plugins: 0.10.24 - only LGPL - bump depends versions gstreamer0.10-python: 0.10.16 Gr, Thijs

[arch-general] [initscripts] Please revert last commit 757f653
by Gerardo Exequiel Pozzi 24 Aug '09

Hi Please revert the last commit[#1], mounting /dev as NOEXEC is incorrect. This break nvidia GLX extension, vmware, mplayer and possible others programs that uses mmap() with execute privilege. PS: I guess that setting a size is "redundant" Thanks.

[arch-general] PHP 5.3 - just takes a bit of reconfiguring, but then works fine
by David C. Rankin 23 Aug '09

23 Aug '09

Listmates, In case any of you pull php 5.3 from testing and suddenly have all your web apps die, I thought I would pass along a few heads-up to save you reinventing the wheel. First Peirre Schmitz put out a few notes on the arch-dev list that provided the answer, but there was a lot that had to be read between the lines to appreciate the notes. I run several php intensive apps (eGroupware, Gallery2, and to a lesser extent squirrelmail) all of which went south when the 5.3 upgrade occurred (well, all of php went south with the upgrade, but it was purely a new configuration issue). The short version of what is required to put php5.3 in place? (1) You need to use the php.ini.pacnew file you will find in /etc/php and merge your php.ini setting into it; (2) You will need to rework the following 2 settings: open_basdir = include_path = ".:..." Specifically, you will need to pay careful attention to any trailing '/'s you have on the path definitions (or prefixes in the case of include_path) because any trailing slash now prevents php from descending further than the specified directory in search of any includes or opens it is looking for. This is what really cost a bit to time to chase down. Note, the changes are not all 5.3, but the effect of the changes in 5.3 will expose any error in the entries. I had 5.2.9 running fine, but I had a few extra '/'s terminating search paths that somehow worked, but in 5.3 that wouldn't fly. (3) PHP5.3 split php for arch into a number of different packages. From Pierre's post: php php-apache php-cgi php-curl php-enchant php-gd php-gmp php-intl php-ldap php-mcrypt php-odbc php-pear php-pgsql php-pspell php-snmp php-sqlite php-tidy php-xsl You will need to install what you need and see the post in arch-dev for specifics of sqlite, (what's needed for Ver. 2, and Ver 3.), etc... (4) After you install the packages, you will now need to specifically uncomment any of the extensions you need to load or have loadable from withing php.ini. (eg. extension=mysql.so; extension=odbc.so; extension=openssl.so, etc...) After going through this bit of unintended learning, PHP 5.3 is working smoothly as far as I can tell, logs are clean, a few derprecated warning for things that will disappear in php 6, but other than that, nothing. The last issue I found in php 5.3 is it checks for the absence mysql_free_result after mysql queries and warns if it isn't found. This may be something I just didn't notice in the earlier releases, but it provided the opportunity to clean up a few. That's it, hope it saves somebody a few extra minutes of time. -- David C.
