History

Deimos 5fbc72c44c Add ability to process posts with Lua scripts This adds the backend pieces (no interface yet) to configure Lua scripts that will be applied to topics and comments due to different events. Initially, it only supports running a script when a new topic or comment is posted. For example, here is a Lua script that would prepend a new topic's title with "[Text] " or "[Link] " depending on its type, as well as replace its tags with either "text" or "link": function on_topic_post (topic) if (topic.is_text_type) then topic.title = "[Text] " .. topic.title topic.tags = {"text"} elseif (topic.is_link_type) then topic.title = "[Link] " .. topic.title topic.tags = {"link"} end end There can be a global script as well as group-specific scripts, and the scripts are sandboxed, with limited access to data as well as being restricted to a subset of Lua's built-in functions. The Lua sandboxing code comes from Splash (https://github.com/scrapinghub/splash). It will need to be modified, but this commit keeps it unmodified so that future changes can be more easily tracked by comparing to the original state of the file. The sandboxing also includes some restrictions on number of instructions and memory usage, but this might be more effectively managed on the OS level. More research will still need to be done on security and resource restrictions before this feature can be safely opened to users.		4 years ago
