Before running checksetup.pl

  • run the Sanity Check function from the Admin page
  • make sure that in extensions/Voting/ there is NO file called "disabled" otherwise we disable voting! (MUST run checksetup.pl afterwards in case of deleting that file!)
  • Reapply diff for bugzilla-4.0/Bugzilla/BugMail.pm to bugzilla-4.2/Bugzilla/BugMail.pm (see bugzilla:43130.
  • I needed to run:
    /usr/bin/perl install-module.pl Math::Random::ISAAC
  • I ignored: "WARNING: You need to set the max_allowed_packet parameter in your MySQL configuration to at least 3276750. Currently it is set to 1048576. You can set this parameter in the [mysqld] section of your MySQL configuration file."
  • Due to https://bugzilla.mozilla.org/show_bug.cgi?id=736057 you MUST run
    find . -type f -name "*.tmpl" -exec replace 'FILTER url_quote' 'FILTER uri' -- {} \;
    in order to fix

Test after upgrade

  • Voting! If it does not work, we did not remove the "disabled" file in /extensions/Voting
  • Check if extension https://bugzilla.wikimedia.org/weekly-bug-summary.cgi?tops=10&days=7 works at all - see above.
  • Navigation > Help is broken in 4.2.4, links to non-existing /docs/en/html/bug_page.html . 4.0.9 links to /docs/en/html/index.html
  • /reports.cgi says "Unable to open the chart datafile /var/lib/bugzilla./data/mining/-All-" locally here, but might be because of missing data.
  • Ignore wikimedia/bugzilla/modifications/bugzilla-4.0/client/ (after having contacted Mark A. Hershberger).

After all is done

  • Set announcehtml in Bugzilla to
<div id="message">Wikimedia Bugzilla was upgraded to a new software version on Dec 04th, 2012. If you find problems with Bugzilla itself please <a href="https://bugzilla.wikimedia.org/enter_bug.cgi?product=Wikimedia&component=Bugzilla">file a bug report</a>.</div>
