    How to update a multisite Drupal 6/7 installation using Drush

    25th August 2014

    There are quite a lot of posts on how to do this, but my differs a tiny little bit, so I’m saving it for my own future reference, and also for the benefits of the wider audience.

    I am updating a multisite Drupal 6 installation. To the best of my knowledge, the only difference for Drupal 7 is that instead of the site_offline D6 variable the maintenance_mode variable is used in D7.

    On Debian stable and later, you can sudo aptitude install drush and then just use it immediately after that.

    Note: I recommend su webuser (or sudo -s followed by sudo -s -u webuser) before you run any non-testing drush commands, where webuser is the user which owns your web-exposed files (e.g. Debian’s default is, I think, www-data). I’ve seen a lot of recommendations to run drush as a super-user, but that does not make sense, and may actually cause problems with file ownership.

    One last thing before we start: if your drush seems to work fine but hangs when untarring modules – check this solution.

    drush pm-update fails: tar hangs when extracting *.tar.gz module archives from drupal.org

    25th August 2014

    Drush is awesome, especially for updating multisite Drupal installations.
    I had only started using it a few days ago, and I’ve immediately hit a problem, to which I did find a workaround.

    Symptoms

    • running drush @sites pm-update results in normal execution up to after answering ‘y[es]‘; then drush seems to hang indefinitely (haven’t waited beyond about 10 minutes, maybe it does produce an error after a long while);
    • running the same command with --debug shows that drush hangs when trying to untar the downloaded module.tar.gz archive; there are no errors/warnings, it just hangs with no CPU usage;
    • trying to untar any of the modules downloaded from drupal.org manually is also unsuccessful: tar -xzvf module.tar.gz seems to do nothing, it also hangs with zero CPU usage/time and no warnings/errors;
    • interestingly, if I create some test.tar.gz locally, tar does happily extract that;
    • finally, running strace tar -xzvf module.tar.gz shows a number of unexpected lines, such as references to NSS and libnss files (I am only showing some of the lines of strace output, including the last line):

      open(“/etc/nsswitch.conf”, O_RDONLY) = 4
      read(4, “# /etc/nsswitch.conf\n#\n# Example”…, 4096) = 683
      open(“/lib/x86_64-linux-gnu/libnss_nis.so.2″, O_RDONLY) = 4
      open(“/lib/x86_64-linux-gnu/libnss_files.so.2″, O_RDONLY) = 4
      open(“/etc/passwd”, O_RDONLY|O_CLOEXEC) = 4
      open(“/usr/lib/x86_64-linux-gnu/libnss_mysql.so.2″, O_RDONLY) = 4
      open(“/etc/group”, O_RDONLY|O_CLOEXEC) = 4
      open(“/etc/libnss-mysql.cfg”, O_RDONLY) = -1 EACCES (Permission denied)
      open(“/etc/libnss-mysql-root.cfg”, O_RDONLY) = -1 EACCES (Permission denied)
      futex(0x7fd0816e8c48, FUTEX_WAIT_PRIVATE, 2, NULL

    Drupal Views: how to display random nodes/content

    4th May 2009

    Today I had a task of displaying random node in a Views-generated sidebar block.

    This is how to do that in Drupal 7 (Views 3):

    1. edit the view which makes the block available (follow http://your.site/admin/build/views/viewname/edit)
    2. in the Sort Criteria section (under Filter), look for and add Global:Random.

    This is how to do that in Drupal 6 (Views 2):

    1. edit the view which makes the block available (follow http://your.site/admin/build/views/viewname/edit)
    2. in the Sort Criteria section, add the Random criteria.

    It can’t be simpler than that.

    Drupal theme development: where to start

    8th June 2008

    Simplest way to develop your custom Drupal theme is to start with some skeleton/wireframe theme.

    In this post, I’m briefly reviewing 4 themes (atck, blueprint, framework, and zen), made specifically to serve as theme developer’s starting point. All 4 are listed with their features (as per Drupal project page of each one), with my personal “impressions” (not based on actual use experience, yet). There’s also my choice and order of preference for the 4 candidates at the end.
