Could not reproduce in Centos 8 virtual machine.

Guess I'll have to by another SSD to have enough VMs

white lines will be gone with PR fix530

Peek 30-03-2020 19-34

hanspr on 31 Mar 2020

Could not reproduce this either. Also tried with CentOS 7. Will you let us know if you still see the same issue after the changes about transparency (see #530) ?

gfrenoy on 31 Mar 2020

Hi @gfrenoy & @hanspr

I confirm that the white lines are gone after restarting Asbru, but I still get it unresponsive as described initially and I see the following messages in the terminal:

* unhandled exception in callback:
variable not allowed to be undef where GdkRGBA is wanted at /usr/lib64/perl5/vendor_perl/Glib/Object/Introspection.pm line 67.
** ignoring at /usr/share/perl5/vendor_perl/Gtk3.pm line 572.

Will test in Centos 7 and 8 as soon as possible.

Thanks.

popxunga on 31 Mar 2020

Hi @gfrenoy & @hanspr
Just to make it clear:

Even after restarting Asbru, I'm not able to open any terminal until I turn off the transparency setting in the Global preferences. So basically, Asbru become totally unusable when the transparency setting in ON.

popxunga on 31 Mar 2020

I don't see the exact same message but on my VM with Debian 10 + xfce (see #538), when I set terminal support transparency to 1 ; it does stop in the middle of the start at the "Loading Connections" step:

Additional note: it's a plain clean new configuration file ; no connection has been configured at all.

gfrenoy on 31 Mar 2020

These are the lines that make the interface stopping:

https://github.com/asbru-cm/asbru-cm/blob/c38ff96a64bdee81e7757dee240f5c98c8fb9ad7/lib/PACUtils.pm#L3875-L3876

Can you try to comment them out and see if it works "better" (you will likely have the white lines back but it should not crash)...?

In my case, that is the call to get_background_color that makes things wrong. I mean get_style_context is OK.

As far as I can see in the Gtk documentation, get_background_color is deprecated as of 3.16 and should not be used.

Mmmm...

gfrenoy on 31 Mar 2020

gtk3 is a nightmare,

So they remove get_background_color, because they say is useless. Thou they say that the only reason to call it is exactly the reason we use it. And then tell you to use another new fuction that will not return the background color but to render it.

If I use this my $C = $w->get_style_context()->get_property('background-color','normal');

will not work because there is no css definition for the background color for the window.
And if there is one, will have to be again a fixed one in the css definitions.

hanspr on 31 Mar 2020

Hi @hanspr ... nightmare seems to be the right word :-/

popxunga on 31 Mar 2020

😄1

Update

I have ran asbru in manjaro (that is supposed to be the on edge of new libraries) and the get_background_color method still works. So I really do not know what could be going on on EL 7

hanspr on 31 Mar 2020

In Debian 10 + xfce, we have Gtk 3.24.5 and it "works" (I mean it does not crash so the "eval" is not failing) but after you called that fonction, the application stay hung for some reasons.

If I force USE_GB to 0, it does not hang anymore but colors are very strange:

Why did you pick (240,0,0) as the default background color for non dark theme ?

Anyway, at this stage, my best guess is that there is a bug in 3.24.5 (which is the version of libgtk-3.0 shipped with Debian 10). But I'm not sure at all...

gfrenoy on 31 Mar 2020

Sorry made a boo boo, guess it will be faster for you to fix than another merge.

_setDefaultRGBA($$self{_GUI}{main},240,0,0,1);

to

_setDefaultRGBA($$self{_GUI}{main},240,240,240,1);

hanspr on 31 Mar 2020

I was testing it worked by forcing a color I would notice (you did!)

hanspr on 31 Mar 2020

@gfrenoy

the "eval" is not failing) but after you called that function, the application stay hung for some reasons
If I force USE_GB to 0, it does not hang

This is even worst. We need to find a way to test if the get_background_color works or not. To be able to set the right flag correctly.

Or we fix to default values so we do not use get_background_color, ever and forget about it.

hanspr on 31 Mar 2020

The current gtk3 versions on EL7 are:
gtk3-3.22.30-3.el7.i686
gtk3-3.22.30-3.el7.x86_64

popxunga on 31 Mar 2020

gtk3 versions on EL7 are: (...) gtk3-3.22.30-3.el7.x86_64

Mmm, nearly same as mine (3.22.30-1ubuntu4), I'm really confused on the origin of the different behaviors we are observing...

_setDefaultRGBA($$self{_GUI}{main},240,240,240,1);
(...) it will be faster for you to fix than another merge.

Yes done.

Or we fix to default values so we do not use get_background_color, ever and forget about it.

Yes, at least if it does not crash for some versions ...

@popxunga ; if you remove those lines:

https://github.com/asbru-cm/asbru-cm/blob/bd448a5bf7d472d1b238e9fb44b6e3b4e183efcc/lib/PACUtils.pm#L3892-L3895

does it works (I mean: at least does not crash) ?

gfrenoy on 31 Mar 2020

Hi @gfrenoy & @hanspr
Just tested again with latest EL7 loki build (unchanged and with the if clause removed) and observed the same exact symptom and error message in the terminal:

* unhandled exception in callback:
variable not allowed to be undef where GdkRGBA is wanted at /usr/lib64/perl5/vendor_perl/Glib/Object/Introspection.pm line 67.
** ignoring at /usr/share/perl5/vendor_perl/Gtk3.pm line 572.

Note that I never said that Asbru crashes; it gets unresponsive and then I have to close it using the quit option in the tray icon.

Thanks for your support.

popxunga on 31 Mar 2020

Can you test

Transparency on
Just open a local shell, nothing more complicated than that.

hanspr on 31 Mar 2020

@popxunga

Lets do the following tests

Transparency Settings

Transparency on
Open a shell

Different behaviour for terminals

Terminals in main tab
Terminals in tab , but disable terminals in main tab
Terminals in windows

I want to know if the transparency affects the main application, tabs or inclusive windows.

To be 100 % sure is related to the mypaint() routine or is something else.

And if is not too much to ask, add a print above the rgba setting to see if there is some real odd value arriving there. And check the messages.

https://github.com/asbru-cm/asbru-cm/blob/bd448a5bf7d472d1b238e9fb44b6e3b4e183efcc/lib/PACUtils.pm#L3888-L3900

sub mydraw {
    my ($w,$c) = @_;
    my ($r,$g,$b,$a) = ($R,$G,$B,$A);

    print "RGBA:($r,$g,$b,$a)\n";
    $c->set_source_rgba($r,$g,$b,$a);
    $c->set_operator('source');
    $c->paint();
    $c->set_operator('over');
    return 0;

hanspr on 31 Mar 2020

Can you test
* Transparency on

* Just open a local shell, nothing more complicated than that.
Hi @hanspr
If I just mark the transparency checkbox, but let the slider off (left most position), it works (I can open local shell or an ssh session), I get no errors and Asbru stays normal.
If I activate the transparency slider moving it from the left most position somewhere to the right, I get the symptoms described initially.
Thanks !
Edit: I just use tabbed windows (attached into the main window).

I will assume that the print right above the error was identical to the previous ones.

Is very strange, the repeated prints, prove that is not crashing every time just by executing this section. Is at some other point. Or the print just above the error was different that the previous ones.

Bad luck then, the change that suggested has like a 0.0001% chance to work now.

Bad luck then, the change that suggested has like a 0.0001% chance to work now.

Correct... just tried it with the same result :-/

popxunga on 1 Apr 2020

Do you have the possibility to publish this VM or a similar one, with no personal data and this problem. So @gfrenoy and me can connect and use it for testing?

If I can not reproduce this thing, and have a way to trace it, I think that the changes to fix it will be another 0.00001%

If you can write the access info to out personal emails.

Thanks a lot for the time spent on this. See you tomorrow, I will give it a rest.

hanspr on 1 Apr 2020

Hi ...
I would if I could but this is not a VM. Let me try reproduce this on CentOS 7.
If I can't I'll try trace it myself.
Thanks for your support.

popxunga on 1 Apr 2020

I could not reproduce the issue in my CentOS 7 VM.

popxunga on 1 Apr 2020

Hi @hanspr
I ran Asbru with perl -d /usr/bin/asbru.cm and got a few more lines in the stacback trace.
I guess not but does this help ?

* unhandled exception in callback:
variable not allowed to be undef where GdkRGBA is wanted at /usr/lib64/perl5/vendor_perl/Glib/Object/Introspection.pm line 67.

Meanwhile I reinstalled all the perl packages required by Asbru with the ones I've built for CentOS7.
I tried login with a different user to avoid any possible corruption in my account profile config data.
I tried also with a clean Asbru profile in both cases, my user and a test user.
But no success so far.
Will keep trying when I have time.

Thanks.

Hi @hanspr

Following the set_color_background found in the error above, lead me to:

If I'm understanding this correctly, the function call in the line 3785 of PACTerminal.pm never returns (I put a print before and after line 3785, and the print after is not executed).

Thanks.

popxunga on 1 Apr 2020

@popxunga

Incredible job, nicely done. It sounds quite right. The pattern of the color must have changed.

So last debuging lines

https://github.com/asbru-cm/asbru-cm/blob/bd448a5bf7d472d1b238e9fb44b6e3b4e183efcc/lib/PACTerminal.pm#L3807-L3830

Place a prints there, and lets see why the rgb colors are wrong. The $bgcolor must have a different length or format.

sub _setTransparency {
    my $self = shift;
    my $transparency = shift;
    my $bgcolor = shift;
    my $alpha = 1 - $transparency;
    my ($r,$g,$b) = (0,0,0);

    print "bgcolor:$bgcolor\n";
    if (length($bgcolor)==13) {
        ($r,$g,$b) = $bgcolor =~ m/(\w{2})\w{2}(\w{2})\w{2}(\w{2})\w{2}/;
    } elsif (length($bgcolor) == 7) {
        ($r,$g,$b) = $bgcolor =~ m/(\w{2})(\w{2})(\w{2})/;
    }
    print "($r,$g,$b)\n";

Hi @hanspr ..

I get this:

bgcolor:#000000000000
(00,00,00)
* unhandled exception in callback:
variable not allowed to be undef where GdkRGBA is wanted at /usr/lib64/perl5/vendor_perl/Glib/Object/Introspection.pm line 71.
** ignoring at /usr/share/perl5/vendor_perl/Gtk3.pm line 572.

Thanks

Change the code on that section to this. I have tested and it works on my PC.

sub _setTransparency {
    my $self = shift;
    my $transparency = shift;
    my $bgcolor = shift;
    my $alpha = 1 - $transparency;

    my $color = Gtk3::Gdk::RGBA::parse($bgcolor);
    if (!$color) {
        $color = Gtk3::Gdk::RGBA::parse("#000000");
    }
    $color->alpha($alpha);
    $$self{_GUI}{_VTE}->set_color_background($color);
}

Hi @hanspr
Looks like the X process in my machine don't like the last modification.
I'm seeing a significant CPU usage by the X process after enabling transparency on Asbru.
The CPU usage starts immediately after opening the Asbru main Window (no need to open a local shell, ssh, nothing).
Need to do some extra testing. Will keep you informed.
Thanks.

@popxunga

That is to be expected, this is a __hack__ not an actual feature of the terminal. So what it does is that will manually repaint all the background, on any mouse move.

This is why @gfrenoy added this subtle tooltip to the option.

I would have wrote : "as it consumes more cpu"

If we consider the previous code and the new one, the new code uses the internal C++ implementation to do what I did before with regex. So I thing it should be actually faster.

I will do some testing to see if it really performs worst, but I doubt it.

Hi @hanspr

I do see almost one core usage hog only, with the main Asbru Window open and not moving the mouse.

Using the same debug technique above, I see this:

These are the last Asbru startup call's (I start it iconified).
