Re: [orca-list] Freezes in Cawbird Twitter client

I cannot reproduce the hang. When you built pyatspi did you ensure it
was going to be built and installed for python3? I had to do:

PYTHON=python3 ./autogen.sh --prefix=/usr

In order to reproduce the crash, can you tell me how to get ino a
"tweet info" label?

Thanks!

Hi all

many thanks Joanie, Mike.

Testing with PyATSPI / Orca / Cawbird master but hangs still persist.

I open a tweet, press tab key until "source" label and a one more tab
it 
freezes.

focus is in a tweet info label.

Orca crashes finally:

Thanks for tracking that down. I'll release a pyatspi 3.38.1 after 
I've fixed it.

Hi again.

I just confirmed that Orca is hanging due to a call to pyatspi's
findAncestor. I filed
https://gitlab.gnome.org/GNOME/pyatspi2/-/issues/7

Locally I did an early return if the object claims to be its
parent and
Orca master now doesn't hang when using cawbird.

<snark>Instead, Orca says too much because the cawbird links in
question don't have a name or text, and are inside an ancestor
label
which consists of the full tweet text. Yay?</snark>

Thanks Mike.

Orca has sanity checks for the condition of an object reporting
itself
as its own parent. But I just found one case where that sanity
check
isn't happening. I just committed a change in Orca master to
handle
that.

I've not yet installed pyatspi with your fix, but another
*possible*
place where sanity checking in pyatspi may be needed is in
findAncestor. Orca uses that utility quite a bit.

Hi Joanie,

I believe I've fixed the pyatspi issue you reported (and now
I can
reproduce the problem, now that I have cawbird installed),
but it
looks as
though something in orca (or possibly another utility
function in
pyatspi)
is also contributing to a freeze. I'd like to figure out if I
can get
gdb
to give me a python stack trace, but, if I set a breakpoint
on
atspi_accessible_get_parent, then I see a viewport object
reporting
itself
as its own parent, which shouldn't be happening, and it
doesn't
surprise
me that this seems to be causing problems.

I'm afraid this needs to be fixed in pyatspi:

Hello everyone!

Hope you are fine.

killer whale less scary.

Cawbird is a GTK Twitter client, next generation of
Corebird.

https://github.com/IBBoard/cawbird

order to continue working.

I am using Orca 40.RC in Ubuntu 20.04.2.

1. Open Cawbird

2. Press enter on any tweet of your timeline

3. Press tab key until a link


I can see following in terminal running Orca:

(orca:125065): dbind-CRITICAL **:
20:23:04.565:
atspi_accessible_set_cache_mask: assertion 'accessible ==
accessible->parent.app->root || accessible->role ==
ATSPI_ROLE_APPLICATION' failed

(orca:125065): dbind-CRITICAL **:
20:23:04.574:
atspi_accessible_set_cache_mask: assertion 'accessible ==
accessible->parent.app->root || accessible->role ==
ATSPI_ROLE_APPLICATION' failed


^[[2~qTerminado (killed)


My Orca debug file is at:

https://paste.ubuntu.com/p/gS7p8nQ7cB/


What could we do to protect ourselves from this?

Many thanks regards and take care!

Javier
