Re: [orca-list] When testing what looks like an Orca hang

Hi Joanie and all.
When I was trying to reproduce this problem , I found some events that take too long to process. 
Here are some examples:

vvvvv PROCESS OBJECT EVENT object:children-changed:add:system vvvvv
OBJECT EVENT: object:children-changed:add:system detail=(1,0,[section | ])

Also I found in the debug file a lot of the  following messages:
----------> QUEUEING OBJECT:STATE-CHANGED:SHOWING [DEAD] (0,0,0) FROM [APPLICATION | GNOME-SHELL]

Another strange thing, at least in my opinion:

Where is the "speech output" message and the "TOTAL PROCESSING TIME" information? 
Thanks.

Hey José, all.

Thanks for trying. Seems we have both a speech-dispatcher and <something
else> bug on our hands. I still cannot reproduce this, so I reviewed all
the debug.outs sent thus far and added some sanity checks and still more
debugging output. If I'm lucky, the sanity checks will prevent the
problem; if not, maybe the more verbose output will point me closer to
the source of the issue.

Long way of saying: Everyone testing for this problem please pull master
and keep testing. And the resulting debug.out output continues to be
very much wanted.

As always, I really appreciate it!

Hi Joanie and all.
I just get a freeze while doing a google search.

While in FF I pressed ctrl+k,  typed 'linux news' and press the enter key.
After that orca stops. I open a terminal session, kill speech-dispatcher
but orca stays mute. The solution was restart orca.
I tried to execute the same steps but the problem didn't happen again.

Seems that the problem happens when I am using firefox.
Thanks.

Hey all.

Three of you have reported that Orca is hanging/freezing. And I keep not
being able to reproduce it. In one instance, however, it looks like Orca
is not hanging or freezing, but instead is continuing to work. Speech
Dispatcher may have crashed though.

I'm still trying to debug this because, again, I cannot reproduce it as
reported. However, in the case of B.H.'s offending bookmark link, I did
a quick test with spd-say: If in a terminal without Orca running I do:

      spd-say "hello world"

I hear "hello world". But if I replace the string in quotes with the
full URL of doom from B.H., I hear nothing and speech-dispatcher dumps
core. If I have Orca speak the string, however, I hear the string as
expected. So I don't know if I'm doing something "wrong" trying to
reproduce the problem, or if we're using different versions of
speech-dispatcher and mine doesn't have the bug -- or doesn't have the
bug when using speech-dispatcher's API.

Regardless, for those of you experiencing what we have been assuming is
Orca freezing/hanging, when the problem occurs please try the following:

1. Leave Orca running; do not --replace it or terminate it.
2. In a terminal or run dialog, type 'sudo pkill -9 speech*'
3. Alt+Tab around and see if Orca starts speaking again

If it Orca magically resumes working just as a result of killing
speech-dispatcher, knowing that would be helpful.

In addition, if you happen to capture a full debug.out, before you send
it to me search it for the lines which contain "SPEECH OUTPUT:" and ask
yourself: Did I hear Orca say that? If the answer is "no", please
include in your email the start of the series of things you didn't hear.
If speech-dispatcher is crashing, it would be good to have some idea of
what is making it unhappy.

Thanks for all your help with this!
