Lm rebooting after mosaic change

[Daniel]

This is your problem, Mosaic has a design issue and it is limited to few MBs of custom images.  The limit is around 8-9MB but each time you use even same custom image it is still counted as new and added to the total. Run this script once, it will move all custom images to LM images and replace yours with url.  The issue with such solution is that you will not see images from cloud.  This will fix your project and if you still want to use custome images also in cloud then make the size as small as possible.

Code:

require('json')
require('encdec')

mosaickey = 'mosaic30:config:0'

config = storage.exec('get', mosaickey)
-- config = io.readfile('mosaic-backup.json')
config = json.pdecode(config)

icons = {}

relpath = '../../../../scada/resources/icons/'
abspath = '/www/scada/resources/icons/'

function fixicon(tbl)
  local file = tbl.file

  if type(file) ~= 'string' then
    return
  end

  if file:sub(1, 10) ~= 'data:image' then
    return true
  end

  local hash = encdec.md5(file)

  if not icons[ hash ] then
    local poss = file:find('/')
    local pose = file:find(';')
    local posd = file:find(',')

    local ext = file:sub(poss + 1, pose - 1)
    local filename = hash .. '.' .. ext

    local data = encdec.base64dec(file:sub(posd + 1))

    io.writefile(abspath .. filename, data)

    icons[ hash ] = relpath .. filename
  end

  tbl.file = icons[ hash ]
  return true
end

function fixstruct(tbl)
  for key, val in pairs(tbl) do
    if type(val) == 'table' then
      if not fixicon(val) then
        fixstruct(val)
      end
    end
  end
end

fixstruct(config.floors)
fixstruct(config.imported_widgets)

config.custom_icons = icons

config = json.encode(config)
storage.exec('set', mosaickey, config)
