Wikipedia:Shortpages/How to update

From Wikipedia, the free encyclopedia

After downloading a current-pages database dump for the English Wikipedia, I use the following commands:

• mkdir data; mkdir todo
• gunzip -c dl/20050909_pages_current.xml.gz | perl ../scripts/parse-entries2.pl >! data/entries.txt
• perl ../scripts/shortpages.pl

The two Perl scripts are shown below, respectively.

# parse-entries2.pl

use strict;

main();

sub main
{
    my ($text, $title);

    $/ = "</page>";

    while (<>)
    {
        $_ =~ m%^(.*?)<revision>(.*?)</revision>.*$%s;
        $title = $1;
        $text = $2;

        $title =~ s%^.*?<title>(.*?)</title>.*?$%$1%s;
        $title =~ s/ /_/g;
        $title =~ s/\&/\&/g;
        $title =~ s/\>/>/g;

        if ($text =~ m%<text xml:space="preserve" />%)

The old method is to run the following SQL commands on a database dump. This does not remove stubs.

DROP TABLE IF EXISTS temp_sizesmall;

CREATE TABLE temp_sizesmall (UNIQUE KEY `s_id` (`s_id`))
SELECT 
        cur_title AS s_title, 
        cur_id AS s_id, 
        cur_text AS s_text,  
        length(cur_text) AS s_size,
        cur_namespace AS s_namespace,
        cur_is_redirect AS s_is_redirect
FROM cur
WHERE LENGTH(cur_text)<251
LIMIT 1000000;

DELETE 
FROM temp_sizesmall
WHERE s_is_redirect=1;

DELETE
FROM temp_sizesmall
WHERE s_namespace<>0;

ALTER TABLE temp_sizesmall DROP COLUMN s_namespace;
ALTER TABLE temp_sizesmall DROP COLUMN s_is_redirect;

SELECT 
CONCAT(
        '|-\n|', 
        s_size, 
        '||[[', 
        REPLACE(s_title,'_',' '), 
        ']]||', 
        LEFT((REPLACE(REPLACE(REPLACE(REPLACE(s_text,'\n',' '),'\r',' '),'   ',' '),'&','&amp;')),100), 
        '') 
AS List
