Live Update: Delete resource

Feature requests
#1

Continuing on the Live Update suggestions streak, a mechanism for identifying and deleting unused resources left over by a previous version of the game would be nice. As it is now, with often enough patches and content updates it seems like resources stored with store_resource() would just pile up and use disk space on the player’s device indefinitely.

I’m really unsure how this would work. I don’t know if live update content is included in the manifest or not (I assume so), but maybe something like:

local table_of_resource_hashes = resource.list_resources_in_manifest(manifest_ref)
local table_of_resource_hashes  = resource.list_stored_resources()
resource.delete_stored_resource(resource_hash_or_table_of_resource_hashes)

Could not publish LiveUpdate content to AWS

We should be able to detect this when updating the manifest. Any downloaded and stored resource that isn’t part of the new manifest should automatically be deleted. Created a ticket to add this functionality.

As a temporary workaround, whenever I make big updates to the game, I delete liveupdate.arcd, liveupdate.arci and liveupdate.arci.tmp, then call sys.reboot():

local function delete_previous_resources()
  if not env.apkx_main_version or not misc then return false end

  local game_name = sys.get_config("project.title")
  local liveupdate_version_filename = sys.get_save_file(game_name, "liveupdate_version")
  local config = sys.load(liveupdate_version_filename)
  local liveupdate_version = config.liveupdate_version

  if liveupdate_version ~= env.apkx_main_version then
    local deleted_file1 = misc.delete_file(sys.get_save_file(game_name, "liveupdate.arcd"))
    local deleted_file2 = misc.delete_file(sys.get_save_file(game_name, "liveupdate.arci"))
    local deleted_file3 = misc.delete_file(sys.get_save_file(game_name, "liveupdate.arci.tmp"))

    config.liveupdate_version = env.apkx_main_version
    sys.save(liveupdate_version_filename, config)

    if deleted_file1 or deleted_file2 or deleted_file3 then
      sys.reboot()
      return true
    end
  end

  return false
end

where misc.delete_file(file_name) is a NE function that returns true if unlink(file_name) == 0

Just wondering, does this feature is planned to devoped. I am kinda also interested in this :slight_smile:

#5

It’s on our roadmap: https://github.com/defold/defold/issues/4722

But it has not been assigned to a release yet. And I can’t say when. Not in any of the versions currently planned (1.2.172 and 1.2.173 but maybe 1.2.174)

It is nice to hear! Thanks!

Regarding the original feature request, and the workaround, it seems like a first good step would be to remove any (all) liveupdate data.
Is this correct?

Removing individual files is much more involved, so finding a MVP would be good.

I guess yes, the best solution will be to delete all liveupdate data.

#9

Can be this feature assigned to some release? :slight_smile:

#10

Sorry for the slow reply. We intend to come back to Live Update features once the Rive integration is launched. I can’t say for sure when this will be, but perhaps 6 to 8 weeks from now.
