Hello,
I am starting to actively use stream tags and am finding them quite
useful. I have one suggestion:
Tags propagated through a block with a known delay (set_history) should be
adjusted by that delay. For example, an input to an FIR filter gets
reflected in the output after a delay. Since the GR executor has access
to the delay info, there's no reason it should not use it.
Comments?
On a separate note, I have observed a _rare_ case where tags get lost. The
scenario involves an output attached to two inputs. The two inputs
consume data in different (random) chunk blocks. It appears that if one
of the inputs consumes items with the tag well before the second input
gets to the tagged item, the second input sometimes does not see the tag.
I have not debugged this enough to confirm that there's no bug in my code.
Eugene
