I run VDR 2.0.2 on a Raspberry Pi. The device runs continuously, so to avoid
wearing out the SD card or needlessly spinning-up the USB disk drive I run VDR
with the -E- option to prevent saving the EPG every 10 minutes.
Today I created a timer for one programme in a long-running series and was
surprised to find that the Series Link plugin had scheduled timers for earlier
episodes, some broadcast several weeks ago! These timers were then
automatically deleted of course.
Looking at the code, it seems that cleaning up the EPG schedules is a
side-effect of writing the data file, so the -E- option disables both. Having
the EPG grow unbounded is perhaps not desirable on devices such as the
Raspberry Pi which have limited memory and CPU.
Please try the attached patch. This one does compile ;-).
