Steps to reproduce the issue are the following: 1) Click on create new accout. 2) Fill all the required fields. 3) Click on submit/create account. 4) Mediawiki reports the error: Fatal exception of type MWException Enabling $wgShowExceptionDetails, I get the following instead: User::addToDatabase: hit a key conflict attempting to insert a user row, but then it doesn't exist when we select it! Backtrace: #0 /var/www/localhost/htdocs/mediawiki/includes/specials/SpecialUserlogin.php(468): User->addToDatabase() #1 /var/www/localhost/htdocs/mediawiki/includes/specials/SpecialUserlogin.php(453): LoginForm->initUser(Object(User), false) #2 /var/www/localhost/htdocs/mediawiki/includes/specials/SpecialUserlogin.php(236): LoginForm->addNewAccountInternal() #3 /var/www/localhost/htdocs/mediawiki/includes/specials/SpecialUserlogin.php(178): LoginForm->addNewAccount() #4 /var/www/localhost/htdocs/mediawiki/includes/SpecialPage.php(613): LoginForm->execute(NULL) #5 /var/www/localhost/htdocs/mediawiki/includes/SpecialPageFactory.php(487): SpecialPage->run(NULL) #6 /var/www/localhost/htdocs/mediawiki/includes/Wiki.php(291): SpecialPageFactory::executePath(Object(Title), Object(RequestContext)) #7 /var/www/localhost/htdocs/mediawiki/includes/Wiki.php(565): MediaWiki->performRequest() #8 /var/www/localhost/htdocs/mediawiki/includes/Wiki.php(458): MediaWiki->main() #9 /var/www/localhost/htdocs/mediawiki/index.php(59): MediaWiki->run() #10 {main} This is my actual configuration: Mediawiki - 1.21.2 SQLite - 3.7.17 PHP - 5.5.4
Thanks for the great bug report! This looks a lot like bug 41609. Which version (git revision, date, etc) of CentralAuth is this about? Is the patch in https://gerrit.wikimedia.org/r/#/c/69587/ included / applied to your codebase?
The wiki is installed in Gentoo using their ebuild. It seems the file used for the installation is http://download.wikimedia.org/mediawiki/1.21/mediawiki-1.21.2.tar.gz dated 2013-Sep-03 The Gentoo ebuild doesn't seem to be making use of either mediawiki-1.21.2.patch.gz nor the gerrit patch mentioned. I'm gonna retest later with the includes/User.php patch applied.
I get the same error with https://gerrit.wikimedia.org/r/#/c/69587/ patch applied. I'm unable to create any user account.
silmano: Is this still a problem? Still not sure what might be the issue here; maybe also post this to https://www.mediawiki.org/wiki/Project:Support_desk
Yes, the issue is still there. I've already posted the issue in the Support Desk: http://www.mediawiki.org/wiki/Thread:Project:Support_desk/Internal_error_when_creating_a_new_user
I have a similar bug: Product Version MediaWiki 1.21.3 PHP 5.3.3 (apache2handler) PostgreSQL 8.4.9 no extensions used (I was using casauth before). When creating an account I get: User::addToDatabase: hit a key conflict attempting to insert a user row, but then it doesn't exist when we select it! Backtrace: #0 <path to wiki>/includes/specials/SpecialUserlogin.php(468): User->addToDatabase() #1 <path to wiki>/includes/specials/SpecialUserlogin.php(453): LoginForm->initUser(Object(User), false) #2 <path to wiki>/includes/specials/SpecialUserlogin.php(200): LoginForm->addNewAccountInternal() #3 <path to wiki>/includes/specials/SpecialUserlogin.php(181): LoginForm->addNewAccountMailPassword() #4 <path to wiki>/includes/SpecialPage.php(613): LoginForm->execute(NULL) #5 <path to wiki>/includes/SpecialPageFactory.php(487): SpecialPage->run(NULL) #6 <path to wiki>/includes/Wiki.php(291): SpecialPageFactory::executePath(Object(Title), Object(RequestContext)) #7 <path to wiki>/includes/Wiki.php(565): MediaWiki->performRequest() #8 <path to wiki>/includes/Wiki.php(458): MediaWiki->main() #9 <path to wiki>/index.php(59): MediaWiki->run() #10 {main} This setup was working with MediaWiki 1.18 (before a upgrade to 1.21).
I think this bug is not specific for CentralAuth ("MediaWiki extensions"). I think it's a MediaWiki bug (e.g. SpecialUserlogin.php).
