A public key must be added to GitHub when installing private themes.
When the process happens asynchronously (for example if the admin does
not have admin permissions to the GitHub repository), installing
private themes becomes very difficult.
In this case, the Discourse admin can partially install the theme by
letting Discourse save the private key, create a placeholder theme and
give the admin a public key to be used as a deploy key. After the key
is installed, the admin can finish theme installation by pressing a
button on the theme page.
This commit should be a no-op for all existing core outlets. Outlets which are introduced by themes/plugins may see a change in behavior, and should follow the steps below if they want to maintain their previous behavior.
`tagName="" connectorTagName=""` is almost always the correct choice for plugin outlets. 40eba8cd introduced a `noTags=true` shortcut which achieved this, and left a comment saying it should be the future default. This commit does exactly that. To avoid any breaking changes for plugins, all existing plugin outlets have been reviewed and adjusted by following this logic:
1) If `noTags=true`, remove the `noTags` parameter, and do not complete any further steps
2) If `tagName` is not specified, set `tagName="span"` (the previous default)
3) If `connectorTagName` is not specified, set `selectorTagName="div"` (the previous default)
4) If `tagName=""`, remove it
5) If `connectorTagName=""`, remove it
The updates were accomplished with the help of a ruby script:
```ruby
def removeAttr(tag, attribute)
tag = tag.sub /\s#{attribute}="?\w*"? /, " "
tag = tag.sub /\s#{attribute}="?\w*"?}}/, "}}"
tag = tag.sub /^\s*#{attribute}="?\w*"?\n/, ""
tag
end
files = Dir.glob("app/assets/javascripts/**/*.hbs")
puts "Checking #{files.count} files..."
files.each do |f|
content = File.read(f)
count = 0
edits = 0
content.gsub!(/{{\s*plugin-outlet.*?}}/m) do |match|
count += 1
result = match
noTags = result.include?("noTags=true")
tagName = result[/tagName="(\w*)"/, 1]
connectorTagName = result[/connectorTagName="(\w*)"/, 1]
if noTags
result = removeAttr(result, "noTags")
else
if connectorTagName == ""
result = removeAttr(result, "connectorTagName")
elsif connectorTagName.nil?
result = result.sub(/name="[\w-]+"/) { |m| "#{m} connectorTagName=\"div\"" }
end
if tagName == ""
result = removeAttr(result, "tagName")
elsif tagName.nil?
result = result.sub(/name="[\w-]+"/) { |m| "#{m} tagName=\"span\"" }
end
end
edits += 1 if match != result
result
end
puts "#{count} outlets, #{edits} edited -> #{f}"
File.write(f, content)
end
```
Force pushing a commit to a theme repository used to break the updater,
because the system was not able to count the commits behind the old and
new version. This operation failed because a force push deleted the old
commits.
The user was prompted with a simple "500 server error" message.
Themes marked for auto update will be automatically updated when
Discourse is updated. This is triggered by discourse_docker or
docker_manager running Rake task 'themes:update'.
Allowing the editing of remote themes has been something Discourse has advised against for some time. This commit removes the ability to edit or upload files to remote themes from Admin > Customize to enforce the recommended practice.
