[arch-general] Mariadb eats system ressources
by rumpelsepp＠sevenbyte.org 09 Oct '14

09 Oct '14

Hi, after struggling with this problem for one week I have finally decided to post on the arch list for getting some help. I have a very strange problem with mariadb from the official repos. I run a usual LAMP stack (apache, php-fpm, mariadb) on archlinux. Since one week (or so) I have realized a very strange behavior: One mariadb process stucks on 100 percent CPU usage. I am not able to figure out what's going on. Restarting mariadb fixes the problem for a few hours. Here is a list of a few debug outputs [1]; I have put it in my pastebin because my email client would wrap the text at 80 chars. If you need even more information I can update the paste. The mariadb status page shows about 6,5 queries per second (!) and I don't know where this comes from. I have disabled remote access with "skip-networking" (mysql port is closed) and the PROCESSLIST does only show one process. I thought it might be an DDoS attack on a website but no apache access-log grows unexpectedly. Even after stopping apache mariadb stucks on 100 percent cpu usage. I figured out that there are listed a lot of connections in the output of "show status like 'Con%';". Last hour I even had about 5000 connections but there are no appropriate queries visible in the general log. The general log lists the wordpress queries which are executed when I click on my homepage. Everything looks fine; the cpu usage does not! Do you have any ideas what I can do to figure out what's going on with my mariadb? Thanks in advance! Stefan [1]: http://snippets.sevenbyte.org/8/raw/

Helo everyone, since some weeks I have a new laptop. Until now everything seemed to work fine. But I can't get youtube to play videos better than 360p, which s quite ugly. Does anyone have a hint on this? I installed flasplayer from adobe and gst-plugins-base/bad/ugly. Best, Heiko

I'm in the process of setting up a Drupal 7.xx site and have com to the point where it recommends using PECL uploadprogress to provide feedback on the progress of file uploads but I'm unable to find any Arch specific install instructions, only those for .rpm or .deb files. This is the first time I have done much with php. any help would be welcome. mik

[arch-general] systemd timers: switch default target to timers.target?
by Neitsab 08 Oct '14

08 Oct '14

Hi everybody, It seems like systemd now provides a target that is intended to gather all timers supposed to be activated after boot. From man 7 systemd.special: > timers.target > A special target unit that sets up all timer units (see > systemd.timer(5) for details) that shall be active after boot. > It is recommended that timer units installed by applications get > pulled in via Wants= dependencies from this unit. This is best > configured via WantedBy=timers.target in the timer unit's > "[Install]" section. systemd package itself provides two timers, /usr/lib/systemd/system/systemd-readahead-done.timer and /usr/lib/systemd/system/systemd-tmpfiles-clean.timer, the latter being statically enabled in the "new" /usr/lib/systemd/system/timers.target.wants directory. Five other packages in base group provide systemd timers: logrotate, man-db, mdadm, shadow and util-linux. I didn't manage to use pkgfile to get this list (globbing and regex switches didn't help, dunno why), so I only counted .timer files present in /usr/lib/systemd/system/. $ pacman -Qo /usr/lib/systemd/system/*.timer /usr/lib/systemd/system/fstrim.timer is owned by util-linux 2.25.1-1 /usr/lib/systemd/system/logrotate.timer is owned by logrotate 3.8.7-3 /usr/lib/systemd/system/man-db.timer is owned by man-db 2.6.7.1-1 /usr/lib/systemd/system/mdadm-last-resort@.timer is owned by mdadm 3.3.1-2 /usr/lib/systemd/system/shadow.timer is owned by shadow 4.2.1-1 /usr/lib/systemd/system/systemd-readahead-done.timer is owned by systemd 216-3 /usr/lib/systemd/system/systemd-tmpfiles-clean.timer is owned by systemd 216-3 Currently, three timers are statically enabled via symlinks in /usr/lib/systemd/system/multi-user.target.wants/ after install (logrotate.timer, man-db.timer and shadow.timer), while as already said systemd-tmpfiles-clean.timer is statically enabled via a symlink in /usr/lib/systemd/system/timers.target.wants/ (seemingly respecting new practice). On the other hand, util-linux' fstrim.timer, when enabled via systemctl, gets symlinked in /etc/systemd/system/multi-user.target.wants/. Other packages not part of base like extra/pkgstats or extra/mlocate also provide timers that once enabled, get symlinked to /usr/lib/systemd/system/multi-user.target.wants/. So AFAICT, there are quite some discrepancies concerning how systemd timers are implemented. I'd like to discuss whether Arch should switch default timers target for packages in base group from multi-user.target to timers.target, possibly doing so for other packages in official repos. Cheers, Neitsab

[arch-general] mobile phone internet access
by message 05 Oct '14

05 Oct '14

Readers, Having read the web page 'android tethering', I write praying that a novice user is _not_ expected to have root access to a mobile phone, openvpn, android sdk etc. etc.! Currently using an old RPM distribution on another portable computer, internet access via an android mobile phone and usb cable is achieved by simple insertion of the usb cable into the computer! Mobile tethering is activated on the phone and "voila!", a dialogue window appears confirming internet access. Could someone please indicate: is this possible in arch linux? Anyway, on the other old(er) computer running arch linux, wicd was installed, but fails to recognise mobile phone internet access either via usb connection (tether mode) or wireless hotspot activation. Below is the wicd error log. --------------------------- wicd initializing... --------------------------- wicd is version 1.7.2.4 768 did not find backend in configuration, setting default external setting backend to external trying to load backend external successfully loaded backend external trying to load backend external successfully loaded backend external Automatically detected wireless interface wl... did not find wireless_interface in configuration, setting default wl... setting wireless interface wl... automatically detected wired interface eth0 did not find wired_interface in configuration, setting default eth0 setting wired interface eth0 did not find wpa_driver in configuration, setting default wext setting wpa driver wext did not find always_show_wired_interface in configuration, setting default False did not find use_global_dns in configuration, setting default False setting use global dns to False did not find global_dns_1 in configuration, setting default None did not find global_dns_2 in configuration, setting default None did not find global_dns_3 in configuration, setting default None did not find global_dns_dom in configuration, setting default None did not find global_search_dom in configuration, setting default None setting global dns global dns servers are None None None domain is None search domain is None did not find auto_reconnect in configuration, setting default True setting automatically reconnect when connection drops True did not find debug_mode in configuration, setting default False did not find wired_connect_mode in configuration, setting default 1 did not find signal_display_type in configuration, setting default 0 did not find should_verify_ap in configuration, setting default 1 did not find dhcp_client in configuration, setting default 0 Setting dhcp client to 0 did not find link_detect_tool in configuration, setting default 0 did not find flush_tool in configuration, setting default 0 did not find sudo_app in configuration, setting default 0 did not find prefer_wired in configuration, setting default False did not find show_never_connect in configuration, setting default True Wireless configuration file not found, creating...

[arch-general] Package guidelines for apps requiring a specific Java version
by Maxwell Anselm 04 Oct '14

04 Oct '14

I'm working on a PKGBUILD for a Java app that must be built and run using Java 8, but I couldn't find any guidelines on best practices for such a situation. The easy part is including 'java-environment=8' and 'java-runtime=8' in makedepends and depends respectively, but how to ensure the right version is set as default when building and running (rather than spitting out the opaque Java errors you get when using the wrong version)? Right now at the start of build() I have echo "Checking that default Java is version 8..." java -version 2>&1 | grep 'version "1.8' Which seems reasonable since building is infrequent. But what about for the shell script that starts the app? I could put a similar check there, but that seems like it would be really annoying for people who have multiple Java versions installed. Could there be a good way of letting my app always use Java 8, even if some other version is set as the default? Thanks, Max
