Avoiding memory issuesEdit

This script may run into memory issues. To avoid this you may like to set a last page_id to refresh.

php refreshLinks.php --e 1500

To do the next set of page_ids you enter

php refreshLinks.php --e 3000 -- 1500

Just continue until all page ids in your wiki were refreshed.

If you forgot to set a last page_id to refresh and the script runs out of memory simply rerun it with the last output page_id as the article to start at, e.g.

php refreshLinks.php -- 1600

Chunking refreshLinks.php to refresh all links without memory leakEdit

Below is an example script to run refreshLinks.php against all pages but without having memory issues.

num_pages=$(php /path/to/mediawiki/maintenance/showSiteStats.php | grep "Total pages" | sed 's/[^0-9]*//g')
end_id=0
delta=2000

echo "Beginning refreshLinks.php script"
echo "  Total pages = $num_pages"
echo "  Doing it in $delta-page chunks to avoid memory leak"

while [ "$end_id" -lt "$num_pages" ]; do
start_id=$(($end_id + 1))
end_id=$(($end_id + $delta))
echo "Running refreshLinks.php from $start_id to $end_id"
php /path/to/mediawiki/maintenance/refreshLinks.php --e "$end_id" -- "$start_id"
done

# Just in case there are more IDs beyond the guess we made with showSiteStats, run 
# one more unbounded refreshLinks.php starting at the last ID previously done
start_id=$(($end_id + 1))
echo "Running final refreshLinks.php in case there are more pages beyond $num_pages"
php /path/to/mediawiki/maintenance/refreshLinks.php "$start_id"
