Series.searchTasks() always returns an empty collection

There's really no need to include the tags in the bug title. That's what the 'tags' field is for :)

Now that I've access to the code, I understand what's going wrong here. The omit_targeted search parameter of the searchTasks() method defaults to `True`, which makes sense for searchTasks() in general but not for searchTasks() on distro series, because we explicitly query for a target here. This default behavior results in a SQL statement like

[...] BugTask.distroseries = 3 AND [...] AND BugTask.distroseries is NULL AND BugTask.productseries is NULL [...]

which of course always returns an empty result.

I would be more than happy to help to fix this, if somebody could show me the best way to change the default value distro series objects only. Or is it not a bug in launchpad, but in the client (launchpadlib) which has to take care of sensible default values?
The attachment lists the SQL statements for the web UI and API calls, maybe the API statement could also be changed to be as simple as the web one by changing the default value of the status parameter.

This is definitely a bug in Launchpad, not launchpadlib.

I think the best way to fix this would be to define searchTasks() on
IDistroSeriesPublic and make sure that omit_targeted defaulted to True
instead of being copied from IBugTaskSearch.

The branch lp:~allenap/launchpad/patch-report-for-people-and-teams-bug-506018 has a registration of BugsPatchesView for IPerson as well as IHasBugs. As part of fixing this bug (or soon after) we should remove the IPerson registration.

Wrong bug, please ignore my previous comment.

Fixed in stable r11458 <http://bazaar.launchpad.net/~launchpad-pqm/launchpad/stable/revision/11458>.

This issue can still be reproduced, so I am re-opening this bug.

Apparently I don't have the right to re-open, could someone in the Launchpad team take a look at this bug?

Could you explain what you command you are using that isn't working? It works for me.

I am basically running the commands in the bug description.

>>> ubuntu = launchpad.distributions["ubuntu"]
>>> xenial = ubuntu.getSeries(name_or_version="xenial")
>>> list(xenial.searchTasks())
[]

[t for t in zesty.searchTasks()] also returns empty.

My python-launchpadlib is 1.10.3-3.

What version of the Launchpad API are you connecting to? It works for me
with devel, but not with 1.0.

Brian, you are right. I didn't specify version='devel' when logging in. After I have added that, the result is no longer empty.
Thanks for the help.
