My preference would be to keep SrvrPowerCtrl's blocking mechanism
simple: a set block blocks all actions, period. Setting a block ought
to be, imho, at the discretion of any plugin's author. Let them decide
if they think their process is important and ought not to be
interrupted.
If a plugin author wants to set a "discretionary" block, i.e. one that
can be easily cleared by the user, then he/she can use this syntax:
Code:
--------------------
[srvrpowerctrl setblock blocking_message_to_display viacli]
--------------------
If SrvrPowerCtrl sees a block request as coming from the "viacli" user,
then the block is clear-able by anyone from any of SrvrPowerCtrl's
menus, player, SBC, webUI, whathaveyou. In this scenario, the blockcode
isn't required to clear the block. A simple menu selection does it.
This method has the additional advantage that the blocking plugin
doesn't have to "remember" the block code. The block can be cleared
via:
Code:
--------------------
[srvrpowerctrl clearblock clearing_message_to_display viacli]
--------------------
