When attempting to access a MediaWiki installation via IPv6 (using the IP address 2001:5c0:1400:a::df), I get the following error: Unable to determine IP Backtrace: #0 /var/www/helpmebot.org.uk/w/includes/User.php(1517): wfGetIP() #1 /var/www/helpmebot.org.uk/w/includes/db/Database.php(676): User->getName() #2 /var/www/helpmebot.org.uk/w/includes/db/Database.php(1046): DatabaseBase->query('SELECT lc_valu...', 'LCStore_DB::get') #3 /var/www/helpmebot.org.uk/w/includes/db/Database.php(1130): DatabaseBase->select('l10n_cache', Array, Array, 'LCStore_DB::get', Array, Array) #4 /var/www/helpmebot.org.uk/w/includes/LocalisationCache.php(764): DatabaseBase->selectRow('l10n_cache', Array, Array, 'LCStore_DB::get') #5 /var/www/helpmebot.org.uk/w/includes/LocalisationCache.php(318): LCStore_DB->get('en', 'deps') #6 /var/www/helpmebot.org.uk/w/includes/LocalisationCache.php(347): LocalisationCache->isExpired('en') #7 /var/www/helpmebot.org.uk/w/includes/LocalisationCache.php(259): LocalisationCache->initLanguage('en') #8 /var/www/helpmebot.org.uk/w/includes/LocalisationCache.php(205): LocalisationCache->loadItem('en', 'defaultUserOpti...') #9 /var/www/helpmebot.org.uk/w/languages/Language.php(473): LocalisationCache->getItem('en', 'defaultUserOpti...') #10 /var/www/helpmebot.org.uk/w/includes/User.php(1059): Language->getDefaultUserOptionOverrides() #11 /var/www/helpmebot.org.uk/w/includes/User.php(1967): User::getDefaultOptions() #12 /var/www/helpmebot.org.uk/w/includes/parser/ParserOptions.php(207): User->getOption('numberheadings') #13 /var/www/helpmebot.org.uk/w/includes/parser/ParserOptions.php(159): ParserOptions->initialiseFromUser(Object(User)) #14 /var/www/helpmebot.org.uk/w/includes/Article.php(4403): ParserOptions->__construct(Object(User)) #15 /var/www/helpmebot.org.uk/w/includes/Article.php(839): Article->getParserOptions() #16 /var/www/helpmebot.org.uk/w/includes/Wiki.php(477): Article->view() #17 /var/www/helpmebot.org.uk/w/includes/Wiki.php(69): MediaWiki->performAction(Object(OutputPage), Object(Article), Object(Title), Object(User), Object(WebRequest)) #18 /var/www/helpmebot.org.uk/w/index.php(104): MediaWiki->performRequestForTitle(Object(Title), Object(Article), Object(OutputPage), Object(User), Object(WebRequest)) #19 {main} Adding a few echos seems to reveal that the line: $ip = IP::canonicalize( $_SERVER['REMOTE_ADDR'] ); returns nothing. This is currently running r82006.
What webserver are you running. This (mostly) works for me on apache. (otoh, when accessing any special page using ipv6 locally I get white screen of death, which i need to investigate futher)
Apache/2.2.14 (Ubuntu) - http://ipv6.helpmebot.org.uk/~stwalkerster/info.php Might this be related to the fact IPv6 connectivity is being provided via a tunnel from Hurricane Electric?
> This (mostly) works for me on apache. (otoh, when accessing any special page > using ipv6 locally I get white screen of death, which i need to investigate > futher) Just to clarify, I discovered my comment about special pages not working was due to the redirect bug (bug 14977). Its unrelated to your issue.
Can you double-check what $_SERVER['REMOTE_ADDR'] returns? Sounds like we have a couple possibilities: 1) REMOTE_ADDR data provided by the web server is missing or bogus 2) REMOTE_ADDR is fine, but for some reason that value doesn't get normalized correctly by IP::canonicalize()
I created a new script in a different directory which just contained the following code: echo ">" . $_SERVER['REMOTE_ADDR'] . "<"; The output of this is (http://ipv6.helpmebot.org.uk/~stwalkerster/remoteaddr.php): >2001:5c0:1400:a::df< I hope this is what you wanted. (The > < is something I commonly use to check for leading and trailing whitespace)
Regression in r77067: prior to that, IP::isValid('2001:5c0:1400:a::df') returned true.
Fixed in r82093.
