It looks like you're doing it right. The example
gr-blocks/examples/vector___source_with_tags.grc does the same
thing, and also fails to report srcid correctly.
Walked through the process in Python and it works fine.
In [57]: h = pmt.to_pmt('hello')
In [58]: type(h)
Out[58]: pmt.pmt_swig.swig_int_ptr
In [59]: pmt.is_symbol(h)
Out[59]: True
So, probably not a swig problem. Somehow, the 'symbolness' of srcid
is getting lost before it gets to the tag debug block.
Removed the is_symbol() check in tag debug, and got this:
thread[thread-per-block[2]: <block tag_debug (3)>]:
pmt_symbol_to_string: wrong_type : #f
Gave up.

Hey guys,
Can one of you open an issue on the issue tracker? It'd really help if
you can throw up a simple test case, too.
Thanks!
Tom
Turns out that the vector_source does not use the srcid parameter, and
the default srcid for a tag is PMT_F, so everything is working
correctly, just not as expected. The user-supplied srcid is ignored.
It would seem like a good idea to fill in this field. The question is
with what? The srcid supplied with each tag? The actual srcid of the
vector_source, ignoring the supplied value?

This issue is for GNURadio 3.7.4 on Ubuntu 14.04 and gcc 4.8.2,
swig 2.0.11.
I have a simple GRC flow graph consisting of a vector source ->
throttle
-> tag debug. Vector source params:
Vector:[1, ] * 100
Tags: [python_to_tag({'offset': 0, 'key': pmt.to_pmt('PDU'),
'value':
pmt.to_pmt(2.3), 'srcid':
pmt.to_pmt('blocks_vector___source_x_0')}),]
Output looks like:
------------------------------__------------------------------__----------
Tag Debug: Debug tags
Input Stream: 00
Offset: 0 Source: n/a Key: PDU Value: 2.3
------------------------------__------------------------------__----------
The srcid appears to be correctly translated to a pmt symbol in
python
and set in python_to_tag, but in tag_debug_impl.cc:126 the type
check
(pmt::is_symbol(d_tags_itr->__srcid) ?
pmt::symbol_to_string(d_tags___itr->srcid) : "n/a")
is false. Within the debugger the test
pmt::is_bool(d_tags_itr->__srcid)
returns true. I am not sure how to further debug this problem.
Is this
a swig issue? Am I making a mistake in the tag creation?
Appreciate any suggestions.
Jared.
