Bug #1876
automatic recordings after EPG update
0%
Description
Hello,
I have only one rule in automatic recorder - .* ... that means, I am recording everything. Yes I am crazy 
But this works fine.
The problem is that some channels update EPG data frequently, shifting the start of many programs by 2 minutes or 5 minutes or so. And automatic recorder records them all - that means, if a program was scheduled in EPG to start on 14:50, and then rescheduled by EPG to start on 14:55, it records it twice - one recording starts at 14:50 and the other starts at 14:55. Sometimes when rescheduling happens several times, it records one program 4 times or more, and I can find recordings in files ending with -1.ts, -2.ts, -3.ts, etc.
Is this an issue in tvheadend? I would expect it to delete rescheduled recordings before it sets new ones, if they overlap. Can I set any setting in tvheadend to skip overlapped recordings of the same name? Is this a bug?

Updated by One more addition: this seems to be similar like Bug #179
which was fixed by adding dvr_entry_find_by_event_fuzzy() - this function should say if the new EPG info is within plus/minus 10 minutes range of any existing entry and only update the existing one instead of adding new.
One example recording is following:
firstly added to scheduler:
"start": 1387329792,
"stop": 1387331400,
Secondly added to scheduler as:
"start": 1387329600,
"stop": 1387331400,
So it is in the range plus/minus 600 seconds, and should be UPDATED instead of duplicitly ADDED ... strange

Ah, I can see that the part of the code was refactored since then! So the new code is probably broken.

I'm here again to report the problem still exists.
If tvheadend has some recording scheduled, and then the program is rescheduled in EPG (just say 2 minutes later), it stores it as ANOTHER recording (this is wrong). Even if the program ID is the same! For example:
old recording has:
"dvb_eid": 35553,
newly scheduled recording has:
"dvb_eid": 35553,
And the program is recorded twice. This is wrong.
I noticed that in /home/hts/.hts/tvheadend/dvr/log/* the files for both recordings are identical, with the exception of the value of "broadcast". I'm not sure what this is, however I believe there is a bug in tvheadend, all my recordings are recorded twice since our EPG suffers frequent reschedules.
Is there any chance to get this fixed?

Updated by I doubt. The active development is only in the 3.9 tree and the EPG updates are not allowed when the recording is active in 3.9.
