This page contains historical information. It may be outdated or unreliable.
2012hwcp was a common shortcut referring to the currently deployed MediaWiki code on application servers. It represents the path /h/w/c/p/
which was a combination of symlinks resolving to /home/wikipedia/common/wmf-deployment/
, which resolved to /home/wikipedia/common/php/
, which resolved to the current MediaWiki branch (e.g. php-1.17
).
Structure
The canonical place to author /home/wikipedia
was on the deployment server, fenari
. It contained
/home/wikipedia/logs/
- On fenari, received logs from other servers via MediaWiki UDP logging. Later migrated to fluorine./home/wikipedia/syslog/
/home/wikipedia/common/
- The main directory that is synchronised to application servers using scap-1 (then based on dsh and rsync). It contained multiversion, wmf-config and different copies of MediaWiki inphp-{version}
directories. As canary, test.wikipedia.org requests were routed to an unpooled application server that mounted /h/w/c directly from fenari over NFS./home/wikipedia/common/wmf-deployment/
- symlink to the currently primaryphp-{version}
directory (before 2013)./home/wikipedia/common/php/
- symlink to the currently primaryphp-{version}
directory (since 2013).
The /home/wikipedia/common/
directory was then synced with rsync using Scap to each of the Apache servers at /usr/local/apache/common
. Also known by its shortcut as /a/common/
.
In 2014, /usr/local/apache/common
was moved to /srv/mediawiki/
