This commit adds a new Rake task for migrating all of your existing
Wiki content from your database into new Gollum repositories.
The bulk of the logic happens within the `WikiToGollumMigrator`
class which is decently test covered and located in the lib directory.
The new Rake task can be executed by running:
`bundle exec rake gitlab:wiki:migrate`
It will output a nice log of every project that it migrates along
with success or failure messages.
I have used it on my own installation to migrate my Wikis successfully.
The previously failing Spinach steps have been fixed with this commit.
I have also added new steps that cover the entire usage of the Wiki
system.
The new Spinach steps revealed a minor bug in the Delete page process.
The path for the "Delete this page" button was previously set to
`project_wikis_page(@project, @wiki)` when it should have been
using the singular `project_wiki_page(@project, @wiki)` path helper.
The link has been corrected and all steps are now passing.
This commit replaces the old database backed Wiki system with the
excellent Gollum git based Wiki system.
The UI has been updated to allow for utilizing the extra features
that Gollum provides. Specifically:
* Edit page now allows you to choose the content format.
* Edit page allows you to provide a commit message for the change.
* History page now shows Format, Commit Message, and Commit Hash.
* A new Git Access page has been added with the Wiki Repo URL.
* The default page has been changed to Home from Index to match
the Gollum standard.
The old Wiki model has been left in tact to provide for the
development of a migration script that will move all content stored
in the old Wiki system into new Gollum Wikis.
Allow connection to Redis via unix socket, using
unix:/var/run/redis/redis.sock for example.
Default behaviour does not change, except that the full Redis URL must
be configured, with redis:// for tcp or unix: for unix socket.
