Puppet Class: profile::mediawiki::deployment::server
- Defined in:
- modules/profile/manifests/mediawiki/deployment/server.pp
Overview
Class profile::mediawiki::deployment::server
Sets up scap and the corresponding apache site, and rsync daemon.
The parameter “deployment_group” only refers to the group of people able to deploy mediawiki here, so to scap2 users. Scap3-related directories will be owned by wikidev unconditionally.

# Starting with git 2.30.3 (which also got backported to older releases
# as CVE-2022-24765) git changed the default behaviour to add an ownership
# check which prevents git operations by a user different than the one which
# owns the .git directory within the repository. This also applies to the root
# user and was added to git in
# https://github.com/git/git/commit/8959555cee7ec045958f9b6dd62e541affb7e7d9
# When making the change, git upstream added a new config directive 'safe.directory'
# which omits the new safety check for a given directory.
#
# For Scap deployments in T330394, the scap provider was fixed to run all git
# commands of the users owning the directory.
#
# However, for a shared environment like the deployment servers the safe.directory
# option isn't well suited: It doesn't allow globbing and only operates on a single
# directory and no sub directories within. Also allow-listing individual directories
# would need an additional wrapper since deployers currently need to run individual
# git commands. As such, for now we're disabling the new check globally until a better
# fix is available
