[pve-devel] [PATCH widget-toolkit 1/2] data/*Store: drop storeid requirement

[Dominik Csapak]

We never use that and it serves no purpose. It probably was meant
to be the upstream config 'storeId' which would add the store to
the Ext.StoreManager. This is unpractical though, since then the
store has to be explicitely destroyed, otherwise the StoreManager
retains a reference and the GC cannot remove the store.

Since donwstream users of the store can simply give the 'storeId'
property anyway if they need to be managed by the StoreManager,
drop the requirement here.

i tried to measure the memory impact of the StoreManager, but i did not
find an easy way to deterministically find out. On average though,
using 'storeId' everywhere, we retained a bit more memory (single
digit percentage difference) as far as i could see.

but since we never actually use that functionality, i'd opt for
not doing it by default and if we need it for a single store,
do it manually (and then make sure the store gets removed again)

if we apply this, i can prepare patch series to remove the
'storeid's from pve/pmg/pbs
