Hello,

Yesterday I tried to disable commercial flagging in mythtv 0.27.4+fixes.2014 (or at least change the default for new recordings)[1].

According to the documentation, e.g. https://www.mythtv.org/wiki/User_Manual:Detailed_configuration_Frontend, under "Setup->TV Settings->General" there should be a screen "General (Jobs)" that has the "Commercial Flagging Method" setting. It doesn't.

In fact a number of settings appear to be missing.

So I went to change the setting in mythweb, only it isn't there either.

So I looked at the mysql database, where I noticed I have duplicate settings.

mysql> select * from settings where value='JobAllowCommFlag'; +------------------+------+----------+ | value | data | hostname | +------------------+------+----------+ | JobAllowCommFlag | 0 | gandra | | JobAllowCommFlag | 0 | gandra | +------------------+------+----------+ 2 rows in set (0.00 sec)

In fact just about all the Job* settings have duplicates. While they are the same, am wondering if this is why I can't edit the values.

mysql> select * from settings where hostname='gandra' order by value; ... | JobAllowCommFlag | 0 | gandra | | JobAllowCommFlag | 0 | gandra | | JobAllowMetadata | 1 | gandra | | JobAllowTranscode | 1 | gandra | | JobAllowTranscode | 1 | gandra | | JobAllowUserJob1 | 0 | gandra | | JobAllowUserJob1 | 0 | gandra | | JobAllowUserJob2 | 0 | gandra | | JobAllowUserJob2 | 0 | gandra | | JobAllowUserJob3 | 0 | gandra | | JobAllowUserJob3 | 0 | gandra | | JobAllowUserJob4 | 0 | gandra | | JobAllowUserJob4 | 0 | gandra | | JobQueueCheckFrequency | 60 | gandra | | JobQueueCheckFrequency | 60 | gandra | | JobQueueCPU | 0 | gandra | | JobQueueCPU | 0 | gandra | | JobQueueMaxSimultaneousJobs | 1 | gandra | | JobQueueMaxSimultaneousJobs | 1 | gandra | | JobQueueWindowEnd | 23:59 | gandra | | JobQueueWindowEnd | 23:59 | gandra | | JobQueueWindowStart | 00:00 | gandra | | JobQueueWindowStart | 00:00 | gandra | ...

Just wondering if it is possible to delete the duplicate entries? Or do I have to delete everything and recreate new entries?

Unfortunately, I have shown all the fields above, there are no extra fields, now does there appear to be a unique constraint on value,hostname which would seem like a good idea (possibly because it is a MyISAM table - not sure if a new installation of mythtv would have the same issue or not).

Thanks

Notes:

[1] Sometimes mythtv hangs for large periods of time before playing a recording or in middle of the recording, and I am working on the theory that the commercial detection, despite being "nice", is the cause.

I found the solution: mysql> ALTER IGNORE TABLE settings ADD UNIQUE INDEX idx_unique (value,hostname); Query OK, 1024 rows affected (0.09 sec) Records: 1024 Duplicates: 20 Warnings: 0 This has been raised as a bug report against mythtv, but instead of fixing it (e.g. creating a unique index), the concerns were dismissed :-( https://code.mythtv.org/trac/ticket/9875 I can now see the settings in mythweb. -- Brian May <brian@microcomaustralia.com.au>
