Make it possible to modify wiki ID

[jamesmontalvo3]

Random notes for how to move a wiki to a new ID (also changes URL). Note that it's more complicated if the wiki is the primary wiki and if you want to avoid outages.

# FIXME: take input from user

# Perform checks on user input
# FIXME #179: This isn't working: spaces and dashes getting through
# FIXME #298: Dashes break MariaDB. Figure out how to allow them.
- assert:
    that: 'wiki_id is search("[a-zA-Z0-9_]")'
    msg: "Your wiki ID may only include letters, numbers and underscores"

# FIXME: 
# IF this is primary wiki:
#  make all wikis read only
# ELSE:
#  make old_wiki_id read-only

- name: Remove any existing database dumps
  file:
    path: "{{ m_tmp }}/{{ env }}_{{ old_wiki_id }}.sql"

  mysql_db:
    state: dump
    name: "wiki_{{ old_wiki_id }}"
    target: "{{ m_tmp }}/{{ env }}_{{ old_wiki_id }}.sql"
  delegate to MASTER

# Make option to move, not copy?

  MOVE:

    dest: "{{ m_uploads_dir }}/{{ new_wiki_id }}"

# FIXME: Move config "{{ m_local_public }}/wikis/{{ old_wiki_id }}" to

#	Do a portion of deploy? Do a portion of create-wiki?
