TypeError: 'SwigPyObject' object is not iterable #4

gerben-b · 2021-12-31T14:21:54Z

Describe the bug
I installed indi and indi-3rdparty and pyindi-client from the latest source (indi 1.9.3) according to the respective README files and ran the example in README.rst in the pyindi-client repository. I ran the server as "indiserver indi_simulator_telescope indi_simulator_ccd"
I got this result:
2021-12-30 18:05:46,465 creating an instance of IndiClient

INDI::BaseClient::connectServer: creating new connection...
2021-12-30 18:05:46,465 Server connected (localhost:7624)

which version of pyindi are you using?
if it is not the 0.2.8, please install it and try again.

I was able to reproduce this error in test https://github.com/indilib/pyindi-client/runs/4797923354
Will look into this

artak-kirakosyan · 2022-01-13T16:48:09Z

@abecadel I have one assumption but can't find time to test it.
Can you please try to build the pyindi lib using the indi library 1.9.3 and test the new build?

I suspect that this errors could be related to indi lib binary being changed and old built swig interface is not working anymore

abecadel · 2022-01-14T01:10:34Z

yes, it's most likely the case, I can look into it in two weeks (vacation)

gerben-b · 2022-01-20T12:36:46Z

In the mean time, I built an xml parser in python to communicate with the indiserver so I don't need this anymore. So, no need to hurry ;-)

abecadel · 2022-01-23T10:44:28Z

reopenning as it's still an issue to fix

abecadel · 2022-01-23T14:15:32Z

It appears that the bug was introduced after indi v1.9.0 in indilib/indi#1449 and indilib/indi#1453 - property API has changed

artak-kirakosyan · 2022-01-23T14:52:13Z

@abecadel you are right.
Looks like this problem is present for getProperties method only.
The rest of iterators are fine.

Do you have any experience with SWIG interface files?
I haven't done anything with them so far, if you have been already exposed to it, I would appreciate your help on fixing this.

knro · 2022-02-16T08:23:14Z

Any update on this issue? what can be done to fix it?

artak-kirakosyan · 2022-02-18T14:31:23Z

@knro I am loaded with some other things to do and don't have time to work on this.
We need to investigate the changes done on indilib and reflect changes to PyIndi.
I don't have exposure to c++ so it will take too much time from me, I don't have enough time for this now.

abecadel · 2022-03-05T11:01:18Z

Any update on this issue? what can be done to fix it?

Unfortunately I was unable to fix it myself.
The problem is a new version of properties in libindi is incompatible with current indiclientpython.i, so it needs to be changed accordingly

It appears that the bug was introduced after indi v1.9.0 in indilib/indi#1449 and indilib/indi#1453 - property API has changed
