Re: [orca-list] How to debug Orca-Firefox communication?

Hi Volodymyr,

thank you for your detailed instructions. Even though I am familiar with
general development and build tools, I really do appreciate your effort.
The installation went smoothly and the situation has improved in a way.
Apparently, navigating the web works more reliably now than it did
before. I have, however, managed to produce one more debug log with lots
of ERROR messages even with orca from master. In fact, I started top in
another terminal on the text console and observed that orca ran at 100%
CPU time. Unfortunately, I have not been able to reproduce this since
then, so this makes debugging a bit tricky again.

In normal operation, I am a bit dissatisfied with the responsiveness of
the system when surfing complex websites although, more often than not,
it does not hang altogether any more. In these situations, however, it
is not orca but firefox that seems to be consuming a fair share of
processing time.

Sorry, these are all rather inaccurate findings yet, I still have
difficulties to come up with a good test case. Still, thanks a lot for
your help so far.

Best wishes,

Elias

Hi Elias,
I would suggest to upgrade Orca to the latest version. The steps as follows:


1. Enable the Canonical repositories.
* Open software updater.
* Click the Ubuntu tab.
* Check the box source repositories.
* Click the other software tab.
* Check the boxes next to Canonical partners and Canonical partners
source repositories.
* Click close.
* When requested, click reload cache.

2. Open a terminal window, press Alt+Control+T.

3. Install git, type or copy and paste the following command and press
Enter.
sudo apt-get install git

4. Install build dependencies. Type or copy and paste the following
command and press Enter.
sudo apt-get build-dep gnome-orca

* Answer yes to the ‘do you want to continue?’ prompt.

5. Get the orca source code. Type or copy and paste the following
command and press Enter.
git clone https://gitlab.gnome.org/GNOME/orca.git

6. Build and install orca.
!!WARNING!!
Follow the steps below exactly as typed. Doing something else will
mess up your environment and cause file permission problems.
* Change to your orca repository created in step 5. Type the following
and press Enter:
cd orca

* Configure orca source. Type or copy and paste the following command
and press Enter.:
./autogen.sh

* build orca. Type or copy and paste the following command and press
Enter.:
make

* Install the built binaries. Type or copy and paste the following
command and press Enter.: :
sudo make install

7. When install is complete, restart the system.

After you can keep up with Orca master by executing the following
commands in a terminal:
* first change to the orca folder
cd orca
* look for updates
git pull
* to see what changes are made
git log
* to update
./autogen.sh
make
sudo make install



Best regards

Hi all,

on a machine running Ubuntu 20.04 LTS, I have serious trouble surfing
certain websites. In order to get to the bottom of this, I have created
a new test user. Since I am mostly working on the console, I logged in
and ran:
startx
Then, I started Orca, completed the initial-setup dialogue and started
Firefox. Navigation on the Welcome page worked pretty much as expected.
Next, I pressed Alt+F2 and entered:
orca --debug -r
Back in Firefox, I entered into the address field:
https://www.amazon.de
This is where the system got very slow and generally behaving rather
odd. Pressing the tab key, for instance, was echoed by Orca but did not
bring me to the next link. Arrow key navigation worked (slowly), so I
was able to answer the cookie dialogue. All the same, the system got
almost unresponsive to the point that I had a hard time quitting Firefox
and the Gnome Session.

The debug log is huge and I am rather lost as to what I should be
looking for. It strikes me, however, that there are lots of messages
like these:
ERROR: Event any_data contains defunct child/descendant
The whole file contains 916472 lines capturing a timespan of roughly ten
minutes. There are roughly 18000 lines containing the keyword ERROR
concentrated in a time span of five minutes.

Do you have any advice how to proceed?

Thanks in advance,

Elias
