XAMPP-1.8.3上部署老的mediawiki-1.21.2遇到错误

F:\repo\mediawiki-1.21.2>c:\xampp-1.8.3\php\php maintenance/update.phpMediaWiki 1.21.2 UpdaterGoing to run database updates for fnstwikiDepending on the size of your database this may take a while!Abort with control-c in the next five seconds (skip this countdown with --quick) ... 0Turning off Content Handler DB fields for this part of upgrade....ipblocks table does not exist, skipping new field patch....ipblocks table does not exist, skipping new field patch.Creating interwiki table ...done.Adding default interwiki definitions ...done.Set $wgShowExceptionDetails = true; in LocalSettings.php to show detailed debugging information.

然后遇到了错误：

Warning: preg_match_all(): Compilation failed: group name must start with a non-digit at offset 4 in F:\repo\mediawiki-1.21.2\includes\MagicWord.php on line 876Warning: Invalid argument supplied for foreach() in F:\repo\mediawiki-1.21.2\includes\MagicWord.php on line 877

感觉应该是PHP升级之后API的不兼容导致。

这里：

然后是这里：

https://gerrit.wikimedia.org/r/#/c/107259/1/includes/MagicWord.php

修改之后：

    /**     * Get the base regex     */    function getBaseRegex() {        if ( is_null( $this->baseRegex ) ) {            $this->baseRegex = array( 0 => '', 1 => '' );            foreach ( $this->names as $name ) {                $magic = MagicWord::get( $name );                $case = intval( $magic->isCaseSensitive() );                foreach ( $magic->getSynonyms() as $i => $syn ) {                    // Group name must start with a non-digit in PCRE 8.34+                    $it = strtr( $i, '0123456789', 'abcdefghij' );                    $group = "(?P<{$it}_{$name}>" . preg_quote( $syn, '/' ) . ')';                    if ( $this->baseRegex[$case] === '' ) {                        $this->baseRegex[$case] = $group;                    } else {                        $this->baseRegex[$case] .= '|' . $group;                    }                }            }        }        return $this->baseRegex;    }

但是还是不行，见鬼了

好吧，把数据库直接升级到mediawiki-1.23.3看看：

F:\repo\mediawiki-1.23.3>c:\xampp-1.8.3\php\php maintenance/update.phpMediaWiki 1.23.3 UpdaterGoing to run database updates for fnstwiki-mwDepending on the size of your database this may take a while!Abort with control-c in the next five seconds (skip this countdown with --quick) ... 0Turning off Content Handler DB fields for this part of upgrade....ipblocks table does not exist, skipping new field patch....ipblocks table does not exist, skipping new field patch.Creating interwiki table ...done.Adding default interwiki definitions ...done.Set $wgShowExceptionDetails = true; in LocalSettings.php to show detailed debugging information.Notice: Uncommitted DB writes (transaction from DatabaseUpdater::doUpdates). in F:\repo\mediawiki-1.23.3\includes\db\Database.php on line 4147

结果还是不行：

A database query error has occurred. This may indicate a bug in the software.

看看怎么回事：

$wgDBprefix = "mw_"; //是这里吗？不像

重新运行更新脚本：

终于OK了。这里mediawiki配置文件里table前缀要根据备份的sql文件写对，然后确保运行了数据库更新脚本。
