I’ve been running MediaWiki on top of Apache, PHP and SQLite for some time now. Back when I used PHP 5.2, its SQLite support depended on SQLite 2 – all other apps on my system could cope with SQLite 3, though. When I saw PHP’s USE flag "pdo" depended on SQLite 3 as well, I activated it but I failed to see that the hard dependency on SQLite 2 was still active. I forgot about the USE flag but left it activated. Lately I upgraded PHP to 5.3.3-r1 which depended solely on SQLite 3 when using +sqlite3 instead of +sqlite. So I took this opportunity to get rid of SQLite 2 and threw away the "pdo" USE flag for PHP as well. Since that PHP upgrade, MediaWiki stopped working. Apache gave me these error messages in the error log: [Fri Oct 29 18:37:16 2010] [error] [client ::1] PHP Fatal error: Class 'PDO' not found in /var/www/localhost/htdocs/mediawiki/includes/db/DatabaseSqlite.php on line 56 Fortunately this led me to the solution: recompile PHP with +pdo and I’m done, MediaWiki works again. Now this leads me to the conclusion that MediaWiki used with SQLite needs not only SQLite itself but also PHP compiled with SQLite and PDO support. This should be reflected in the ebuilds. Only mediawiki-1.16.0 seems to have adopted an sqlite USE flag (sqlite3), earlier versions don’t have one. So I suggest: • Add an sqlite (or sqlite3) USE flag to MediaWiki <1.16.0. When this flag is used, the ebuild should depend on dev-db/sqlite as well as dev-lang/php[sqlite3,pdo] • Modify the RDEPEND in MediaWiki >=1.16.0 so when +sqlite3 is used, the ebuild also depends on dev-lang/php[sqlite3,pdo] Reproducible: Always Steps to Reproduce: Probably (not tested like this): 1. USE="sqlite3 -pdo" emerge mediawiki 2. Open a browser on the MediaWiki URL Actual Results: You will get a 500 error (oddly, not properly displayed in either Firefox or Opera, had to use wget to see it) and an appropriate Apache error message in /var/log Expected Results: A working MediaWiki installation due to PDO being automatically USEd. emerge --info says: Portage 2.1.8.3 (default/linux/amd64/10.0/desktop, gcc-4.4.4,

Just for the records: i just tried to create/configure a new mediawiki (1.16.0, build with USE=sqlite3): * php without USE=pdo: sqlite is NOT offered as a database backend * php with USE=pdo: sqlite is offered as a database backend so mediawiki needs dev-lang/php[sqlite3,pdo]
Fixed in CVS. Note that I changed the USE flag to be sqlite rather than sqlite3 for both versions.
