I'm for dropping this topic altogether as there is NO way that anyone,
except the original program, can mark or tell if a timer is modified or not
with a resonable enough reliability.
Every schema we draw up won't work for more than a subset of the cases, so
every programm still has to draw up a solution for the rest of the cases.
Which makes it a pointless affort as you practically always end up having
to remember what you programmed and comparing that to what is programmed
now, to be sure there was a modification or not.
I say that is nothing Klaus should be concerend about as there is not much
VDR can do, as said all schema can't catch all modifications.
VDR can catch:
- Modification via OSD
VDR can not catch:
- Modification via SVDR (telnet or modt.pl)
- Modification via VDRAdmin, XXV ... (technically this is also SVDR)
- MOdification of timers.conf when VDR is not running
- Anything i forgot. :-)
Real Programmers consider "what you see is what you get" to be just as
bad a concept in Text Editors as it is in women. No, the Real Programmer
wants a "you asked for it, you got it" text editor -- complicated,
cryptic, powerful, unforgiving, dangerous.
