Bug#859262: Re: freezes Orca screen reader

[Alex ARNAUD]

I am CC'ing the accessibility list hoping that they might have an
insight to what is happening.  I have quoted the original mail in full
below for their sake.


I'm not yet a Stretch user but the Orca developer has submitted a patch 
to fix this bug : take a look at 
.


Best regards.

If this bug doesn't receive negative feedback about my package, I'll try
to upload the fix to unstable tomorrow.

Just for the record, and I have no idea if it is relevant, but Synaptic
also makes the main Synaptic window and/or its menu items inaccessible
for the sighted people after pressing buttons. This is meant as feedback
that Synaptic is busy. Maybe this behavior has something to do with the
bug at hand (the one in AT-SPI2 I mean).

And I would still appreciate feedback on my package.

@Joanmarie, did you get any feedback on the Orca list?

Thanks Paul.

processing events, presented the window you Alt+Tabbed into, etc.

Having said that, if memory serves me, even before the changes I made,
Orca kept processing events, and probably would have presented the
window you Alt+Tabbed into. In other words, I don't know if, from the
user's perspective, anything has changed. But it appears that I've done
all I can do in Orca (i.e. handling the exceptions it's getting from
AT-SPI2 as a result of querying Synaptic for information via AT-SPI2).

As you have seen, I already created a Debian package with your commits
included. Please find attached a debug log generated while running
Synaptic with this new Orca package (3.22.2 based) and verify that it
looks like intended now.

@all reading this bug, feedback is welcome.

P.S. I'll probably start working on getting Orca to produce sound on my

Do you think we should clone/open a bug for atspi? If so, what severity
level (assuming we can get orca in shape to behave in the current case)?
I would think the answer to the first question is yes, and to the second
question normal (at least < RC if we can fix Orca).

Do you think we should get Synaptic to behave better? I.e. file a bug
there? If so, do we (you?) understand the issue well enough to describe
it properly?

Note that 382c540 may need to be reverted. Hopefully not. But rather
than playing endless whac-a-mole with Atspi errors resulting from
whatever it is Synaptic is doing, I am sanity checking much earlier on
in the process. There is the possibility that doing so will cause other
badly-behaved apps to not be presented. :-/

I've asked on the Orca list for testing, and we have enough users that
use master and respond quite quickly to calls for testing, that we
should know soon enough.

I believe I've already said this, but I'll say it again: Getting to the

I checked out the gnome-3-24 branch and tried to build¹ a Debian package
from that, that I could install. With that, I did again a run of
synaptic upgrade. Please find the attached debug log and hopefully it
contains more useful info.

And to prepare for fixes of the package in Debian (which is 3.22.2 and

So I just handled the value-related "The process appears to be hung"
exception. I saw that you also had the name-related exception. But the
line number suggests to me that you don't have another change I made,
namely to return immediately in isLayoutOnly() if obj is dead. I'm not
positive, but I'm hopeful that check will prevent the name-related
exception. (And if not, I'd like to know that.)

Therefore, before you try to log other issues, would you mind pulling
master or the gnome-3-24 branch so you have the latest?

Thanks again!

Hi Joanmarie,

Yesterday, I send you a log while Synaptic had not much to do, because I
ran it earlier the same day (so maybe the original issue wasn't there).
Today I tried again, hoping that there were updates to apply, which
there were. orca segfaulted on me. Please see the attached stack trace.
Maybe it tells more than the one of yesterday.

paul@testavoira ~/tmp $ orca
/usr/lib/python3/dist-packages/pyatspi/Accessibility.py:184: Warning:
g_object_unref: assertion 'G_IS_OBJECT (object)' failed
  Atspi.Event.host_application = property(fget=lambda x:
x.source.get_application())
Segmentation fault
paul@testavoira ~/tmp $

For people normally running orca, would it get automatically restarted,
such that it would appear to hang, will in reality it was restarting? Or
is it more likely I experienced another bug, maybe related to debugging?
Or maybe the behavior is slightly different between the Debian version
and my (newer) version of orca.

Thanks! From a quick glance, Orca isn't frozen. Orca is still getting
and processing accessibility events even after that error. But it's
getting those events from defunct accessible objects, objects with
ROLE_INVALID, etc.

I'll take a longer look next week and handle the currently-unhandled
error. But the problem may persist. Orca cannot bring defunct/invalid
objects back from the dead; it can only try to gracefully step around
their bodies. Thus getting to the bottom of the Synaptic and/or AT-SPI2
issues needs to occur.

I'd be curious to know what happens if, when the Synaptic issue occurs,
you Alt+Tab into another accessible application. Does Orca present your
interactions with that app?

Thanks again!

I hope the attached log contains enough information for you to work it out.

Mind you, my Orca setup isn't speaking (as can be seen from the top of
the log), but I think it captures the same error as reported in this bug
already.

I created a Debian package for the 3.24 version which I build on
debomatic¹ for this purpose.

Orca knows better than to do that. ;) There may be yet another bad

Well, the application could simply be busy doing other stuff, like
processing huge packages lists for synaptic.  And that's not a reason
for Orca to freeze, for me that's the most important bug to fix: Orca
shouldn't rely on applications behaving correctly.

Hi Paul,


I had a brief look at the code and:

 * You are right that the NameError is expected.  It appears to be some
   method for lazily loading/evaluating values.

 * The actual issue is the other stacktrace.

 * The exception appears to be thrown from accessing an attribute.  I am
   assuming that object/attribute is a reference to an GUI object in
   the synaptic process using a GLib/GTK protocol.

 * I have not seen that error before, but codesearch.d.n helpfully
   points us to [1].

 * From that, I found [2], which suggests atspi concludes synaptic to be
   hung because it does not respond to a dbus "ping" call to
   "org.freedesktop.DBus.Peer".  Not that it makes me any wiser as to
   why the problem occurs.

Time to hunt for some dbus experts who can tell us why a process might
fail to respond to a ping.

Thanks,
~Niels

Not sure if you (Niels) looked at the code, but when I look at it, that
NameError is something that is not uncommon to happen as the whole
exception handling is written exactly to handle that:
https://sources.debian.net/src/gnome-orca/3.22.2-2/src/orca/generator.py/#L233

The "hung" happens in the exception handling (which in itself is also in
a try/except block). To me (but I am not very good in Python and not at
all familiar with Orca) it still looks like synaptic is doing something
that in the end triggers a time out. I hope somebody with more Python
and/or Orca knowledge can shine a light on this.

Thanks Tim, that is a very interesting log file.

Reading the log file, we at least have one bug in Orca itself (a Python
"NameError").  I am not entirely sure whether this bug triggers the
"hung" process or the "hung" process triggers the "NameError".

I am reassigning this bug to gnome-orca for now, so the maintainer of
orca can have a look at it.

@Orca maintainers: The Orca log shows:

"""
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/orca/generator.py", line 234, in
generate
result = eval(formatting, globalsDict)
  File "", line 1, in 
NameError: name 'ancestors' is not defined

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/orca/generator.py", line 245, in
generate
globalsDict[arg] = self._methodsDict[arg](obj, **args)

Hi Mika,

Would it be possible for you to take a screenshot of synaptic + orca
when the problem occurs?  If we are lucky there might be an error
message for us in it that orca is unable to read out loud.

Hi Mika,

Sorry to hear that synaptic is causing you issues.

I am CC'ing the accessibility list hoping that they might have an
insight to what is happening.  I have quoted the original mail in full
below for their sake.

Thanks,
~Niels

(PS: Please CC me on replies if you need my attention.  I am not the
maintainer of synaptic)
