Previously we asked a user to enter a new slug before taking them to
the Create Page page.

As a UX improvement, we now take them to a randomly generated URI so
they can begin creating their new page.

This removes the create_wiki permission check from the history
controller, allowing show and history to have the same level of
permissions.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/29528

Closes #55564
This is first discovered in #54739 (comment 122609857) that if both if: and only:
are used in a before_action or after_action or alike, if: is completely ignored.

Inside a wiki, when we show the sidebar or browse to the `pages`,
all page contents are retrieved from Gitaly and that is a waste
of resources, since no content from that pages are going to be
showed.

This MR introduces the method `ProjectWiki#list_pages`,
which uses new wiki_list_pages RPC call to retrieve
pages without content

Also in the `WikisController` we're using the method to show
pages in the sidebar and also on the `pages` page.

Enables frozen string for some vestigial files as
well as the following:

* app/controllers/projects/**/*.rb
* app/controllers/sherlock/**/*.rb
* app/controllers/snippets/**/*.rb
* app/controllers/users/**/*.rb

Partially addresses #47424.

Without this parameter, every load of a Wiki page will load all the Wiki pages
in the repository for the sidebar. This is a significant performance penalty
that can significant slow the display of all Wiki pages.

Relates to #40101

Added support for custom wiki sidebar using _sidebar.md in the wiki root. If _sidebar.md exists it will be parsed and rendered otherwise the default sidebar file list  will display

deleted _sidebar_custom.html.haml and modified _sidebar.html.haml to check for sidebar_page and render it or the default wiki page list. Also removed white space.

fix indent in show.html.haml

restore newline at end of ile

Add a newline at the end of changelogs/custom_wiki_sidebar.yml

Part of gitlab-org/gitaly#639

Adds a rubocop rule (with autocorrect) to ensure line break after guard clauses.

Add a rubocop rule to check if a method 'redirect_to' is used without explicitly set 'status' in 'destroy' actions of controllers

Remove slash commands from Markdown preview and display their outcome next to
the text field.
Introduce new "explanation" block to our slash commands DSL.
Introduce optional "parse_params" block to slash commands DSL that allows to
process a parameter before it is passed to "explanation" or "command" blocks.
Pass path for previewing Markdown as "data" attribute instead of setting
a variable on "window".
