mythbackend segfault at end of every recording (DVB)

[jppoet@…]

I will attach a backtrace.

Backtrace from 8233

svn 8233 backtrace

In

void DTVRecorder::BufferedWrite(const TSPacket &tspacket)

a call is made to

ringBuffer->Write(tspacket.data(), TSPacket::SIZE);

At the end of a recording, but ringBuffer == NULL.

Changing

ringBuffer->Write(tspacket.data(), TSPacket::SIZE);

To

if (ringBuffer)

ringBuffer->Write(tspacket.data(), TSPacket::SIZE);

will probably fix the segfault, but does this indicate a more serious problem?

thanks,

John

Bandaid to prevent mythbackend from a segfault

[danielk]

(In [8235]) References #793.

This prevents the segfault by applying John Poet's patch. I'll look at why the write is being called at this point before closing the ticket.

[danielk]

I'm closing this, I believe the underlying cause is fixed in [8237]. The DVBRecorder's ringbuffer was being set to NULL before the TeardownRecorder() call, now it should always be called after any TeardownRecorder() call.
