Indeed. I forgot to delete the old .gem directory in my home directory.

After

emerge -av =x11-libs/vte-0.28.2-r207
to get an older VTE from my gentoo package manager

git install works fine. It is not really clear from your pages that
that old vte version is needed.

I did a --user-install again, because rake and other stuff is already
provided on my box by gentoo package manager, and removing all that is
some work. So I did

git clone https://github.com/ruby-gnome2/ruby-gnome2.git
% cd ruby-gnome2
% gem install --user-install rake rake-compiler mechanize pkg-config
cairo
% rake gem:build
% rake gem:install

Followed by changing .bashrc and fixing RUBYLIB

export RUBYLIB=/home/stefan/.gem/ruby/2.2.0/extensions/x86_64
-linux/2.2.0/

export PATH=$PATH:/home/stefan/.gem/ruby/2.2.0/bin

Now I can launch my app, and get mostly deprecated warnings, which I
will fix. Unfortunately still many crashes with messages like

paint newsize
/home/stefan/pet/pet_bbox.rb:17: [BUG] rb_gc_mark(): 0x0000000254d2e0
is T_NONE
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

You told me to look for errors raised in callbacks in your first post.
Will try that. Maybe I can locate the reasons for the crashes.

Thanks.

I tried ruby-gtk3-3.0.5.tar.gz because all my tries to install git
master failed yesterday, because of vte.

Will try again.

The following warning is caused by "sudo make install":

"sudo make install" conflicts with "rake gem:install". You

related files.

vte-0.40.2 provides 'vte-2.91' package. It's not 'vte'
package. ('vte' package is old VTE.)

Why did you use 3.0.5 instead of master?
You already have gtk3 by 'rake gem:install'.
You don't need these command lines. It causes problems.

The good news first: I can launch my program again with 3.05 after a
few fixes. But this is what is logged at the console:

http://ssalewski.de/tmp/msg.txt

The deprecated warnings are not a problem for me, I had that already
when I port the application from gtk2 to gtk3. That is easy to fix. But
all the other messages? No idea currently.

For my current fixes:

class ColBox < Gtk::ComboBox
  attr_accessor :lock
  Col_Name, Col_Pixbuf, Col_Full_Name = 0, 1, 2
    def initialize
    store = Gtk::ListStore.new(String, Gdk::Pixbuf, String)
    Pet_Config::get_default_config.get_colors(Pet_Config::SCR_S).each{|sym, b, c|
      next unless s = Pet_Config::Color_Name[sym] # some colors may have no name/index, i.e. pin hot end color
      iter = store.append
      iter[Col_Name] = "(#{s})"
      iter[Col_Pixbuf] = Gdk::Pixbuf.new(Gdk::Pixbuf::COLORSPACE_RGB, true, 8, 12, 12) # (colorspace, has_alpha, bits_per_sample, width, height)
      iter[Col_Full_Name] = sym.to_s
    }
    super(:model => store)
    self.margin = 0 
    self.id_column = Col_Full_Name
    renderer = Gtk::CellRendererPixbuf.new
    self.pack_start(renderer, false)
    self.add_attribute(renderer, "pixbuf", Col_Pixbuf)
# self.set_cell_data_func(renderer) do |w, renderer, model, iter| # Gtk::ComboBox, Gtk::CellRendererPixbuf, Gtk::ListStore, Gtk::TreeIter
# r, g, b, a = Pet_Config::get_default_config.get_conf(Pet_Config::SCR_S)[iter[Col_Full_Name].to_sym]
# renderer.pixbuf.fill!((r * 255).round * 16777216 + (g * 255).round * 65536 + (b * 255).round * 256 + (a * 255).round)
# end

That is a problem when set_cell_data_func is not available :-(

And here:

class Properties_Widget < Gtk::Notebook
  attr_accessor :main_window # ask for redraw of object if property is changed
  def initialize(main_window)
    super()
    @main_window = main_window
    @grid_sensitive_spin_button_list = Array.new
    self.enable_popup = true
    self.add(w = Box_Widget.new(self))#, :tab_label => 'Box')
    self.set_tab_reorderable(w, true)

So I am not allowed to set the tab_label this way any more. What is the strategy
to find out how to do it now? In the last years, I did it mostly by guessing,
which can take really much time.


That is indeed much more trouble than expected. But what can we do? GTK 3.16 is what people
will use on Linux in these days, and that gives crashes with ruby-gnome2.2.5.

I tried yesterday. First removed all the related Gentoo packages, then

% git clone https://github.com/ruby-gnome2/ruby-gnome2.git
% cd ruby-gnome2
% gem install --user-istall rake rake-compiler mechanize pkg-config
cairo
% rake gem:build
% rake gem:install

I added --user-install and tried without root privileges. Unfortunately
rake gem:install failed for vte. There was no really helpful error
description, but output was "checking for vte ... no" which should be
wrong. x11-libs/vte-0.40.2 is installed from gentoo package manager,

# locate vte.so
/usr/lib64/libvte.so
/usr/lib64/libvte.so.9
/usr/lib64/libvte.so.9.2800.2
/usr/lib64/ruby/site_ruby/2.2.0/x86_64-linux/vte.so

AMD64X2 ruby-gtk3-3.0.5 # locate vte.h
/usr/include/vte-2.91/vte/vte.h

I was not able to locate where the error occurred.

Now I tried to install 3.05 from ruby-gtk3-3.0.5.tar.gz

% ruby extconf.rb
% make
% sudo make install

Compiles, but with a lot of warnings, for example about deprecated
symbols.

But when i try to launch may program:

/usr/lib64/ruby/site_ruby/2.2.0/gobject-introspection/loader.rb:551:in
`invoke': TODO: <CellLayoutDataFunc>(func) callback is not supported
yet. (NotImplementedError)
	from /usr/lib64/ruby/site_ruby/2.2.0/gobject
-introspection/loader.rb:551:in `block in define_method'
	from /home/stefan/pet/pet_prop.rb:81:in `initialize'

Seems to be a regression. Will investigate it, maybe I can avoid
CellLayoutDataFunc.

Currently I have no logs, it was Mr Graaff from Gentoo Linux developer
team who tried to compile gtksourceview. He has much more experience
than I have, have already contacted him again. We will try to send you
logs as soon as possible.

I've fixed it at master.
Cloud you try master?
  https://github.com/ruby-gnome2/ruby-gnome2/#install-from-github-master-branch

There are some bugs in your program. If an error is raised
in callback (block registered by signal_connect), your
program will report Ruby level backtrace, C level backtrace
and so on at exit.

Normally, you should not raise any error in callback because
we can't recover from the error.

Great, thank you very much.

Currently for Gentoo Linux we have GTK/Gnome 3.16 and still ruby-gnome2
-2.2.5 -- and in the last weeks I had many random crashes/segfaults
unfortunately for my application http://www.ssalewski.de/PetEd.html.en

So I did a Google search and found this announcement

https://www.ruby-forum.com/topic/6876851#new

Now my feeling is, that that person is not really a Ruby-Gnome core
developer :-(

You may have seen my plain GTK3 bindings for Nim: 

https://github.com/StefanSalewski?tab=repositories

So I know that it is a lot of work for you and your team to make the
Ruby-Gnome bindings. 

Would be great if we can avoid the crashes in future. I will contact
Gentoo developers again and ask to put latest ruby-gnome2 in the
package repositories -- they already tried with 3.02 but many test
failed and gtksourceview did not compile at all, see
https://bugs.gentoo.org/show_bug.cgi?id=560520

When you are interested in testing your bindings, you may try my
schematics editor from my homepage. Ruby peted.rb should start with an
empty sheet, and you may draw some lines or other graphic elements.
That tool is indeed a very heavy test for ruby-gnome -- it is not yet
finished and contains bugs caused by me. But currently often it crashes
with something like 
 
/usr/lib64/ruby/site_ruby/2.2.0/gobject-introspection/repository.rb:27:
[BUG] Segmentation fault at 0x00000000000018
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

I think that should not occur, and have no idea how to debug/fix that.

[Kouhei S. <ko...@co...>]

Hi,

Ruby-GNOME2 project released Ruby-GNOME2 3.0.4:
  http://ruby-gnome2.osdn.jp/hiki.cgi?News_20150922_1

It is the first release announce of 3.x series. We
re-implemented Ruby/GTK3 as Ruby/GObjectIntrospection based
bindings at 3.0.0. It means that you can use full GTK+ 3
features.

If your program that uses Ruby/GTK3 doesn't work with 3.x,
please report to us. It must be a Ruby/GTK3 bug. We'll fix
the bug.

cedlemo is MVP for releasing 3.0.0. He updates all Ruby/GTK3
samples and confirms their behavior. Very thanks!!!

Hello Peter,

The best thing that I can suggest, is to run a Simple Example, like so:
------------------------------------------------------------------
require 'gtk3'

win = Gtk::Window.new
win.signal_connect("destroy") do
  Gtk.main_quit
end

win.title = "Hello World"
win.show_all
Gtk.main
------------------------------------------------------------------

Then when the Program crashes with the segfault, copy everything that Ruby
Spews out, the backtrace, ruby stack, all of it, and goto
http://github.com/ruby-gnome2/ruby-gnome2 and file a new Bug with the group
there.  Also include, what version you are using, if you are using from a
gem install, or from a git clone from github.  And it may be of interest to
try the latest development version from the Git Repository, to see if the
issue occurs or not, and go from there.  Ruby-Gnome2 is in the process of
converting from pure C bindings, to a C Stub for things that Ruby can't
handle, and the rest being binded through GObjectIntrospection, and the
majority of the work is being done in this tree.

[ruby-gnome2-devel-en] Issues with Ruby/gtk3 on OS X Yosemite

[Peter W A W. <pet...@gm...>]

I’m looking into using Ruby and gtk+3 on Raspberry Pi to see if it can be used by children as young as 7 or 8. First, I need to become familiar with Ruby/gtk3. I’m hoping to do that on my laptop which runs under OS X Yosemite.

I’ve installed X-Windows, gtk+3 and the gtk3 Ruby Gem.

Whenever, I run a Ruby script using gtk3, I get this warning message:

2015-05-04 11:05:36.967 ruby[32956:4463982] *** WARNING: Method userSpaceScaleFactor in class NSView is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead. 

The short sample scripts that I have then work as expected but whenever, I close a gtk3 window, I get segmentation fault:

[BUG] pthread_mutex_unlock: Invalid argument (EINVAL)
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]

...

[BUG] Segmentation fault at 0x00000000000030
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]

I’d appreciate any guidance in how to overcome these issues.

Thanks in advance.

[ruby-gnome2-devel-en] array arguments to boxed constructors

[<jc...@gm...>]

Hello everyone,

I have a boxed type with a constructor declared like this:

/**
 * vips_array_int_new:
 * @array: (array length=n): array of int
 * @n: number of ints
 *
 * Allocate a new array of ints and copy @array into it. Free with
 * vips_area_unref().
 *
 * See also: #VipsArea.
 *
 * Returns: (transfer full): A new #VipsArrayInt.
 */
VipsArrayInt *
vips_array_int_new( const int *array, int n )
{}

Code here:

https://github.com/jcupitt/libvips/blob/master/libvips/iofuncs/type.c#L649

Is it possible to create one of these things from Ruby? I'm getting a
NotImplementedError if I do the obvious thing:

irb(main):015:0> Vips::ArrayInt.new [1,2,3]
NotImplementedError: TODO: Ruby -> GIArgument(array)[gint32]

Re: [ruby-gnome2-devel-en] ref and unref

[<jc...@gm...>]

Ooop, excuse me, I think I found my problem.

gobject-introspection seems to be reffing the object it gets back from
vips_image_new(), even though constructors should not do this (I
think). How can I stop gobject-introspection from making this extra
reference?

If I run this code:

x = Vips::Image.new
x.print_dump

at the end of the C vips_image_new() function, the object has a
reference count of 1. But when x.print_dump runs, I see a count of 2.
When I then run:

x = nil
GC.start

the count drops to 1, but never to zero, so the object is not freed.

I tried adding a (transfer full) annotation to vips_image_new(), but
it made no difference, gobject-introspection still made an extra
g_object_ref() during new.

Thank you for trying this.

That's counting instances of the Ruby classes, which I agree are being
freed. But the underlying GObjects are not being unreffed.

If you put a breakpoint on vips_object_finalize(), for example, it is
never called.

How can I get gobject-introspection to call g_object_unref() whan an
object is removed by GC?

Yes, I'm using 2.2.4.

Really?

I run the code with the following diff:

--
diff --git a/try/try2.rb b/try/try2.rb
index 53c4272..0b214fa 100755
--- a/try/try2.rb

 10000.times do
     Vips::Image.new
 end
+p(ObjectSpace.each_object(Vips::Image) {})
 GC.start
+p(ObjectSpace.each_object(Vips::Image) {})

I got the following:

--
Vips::const_missing: Image
Vips::init: []
Vips::Loader.initialize: Vips, []
Vips::Loader.pre_load: #<GObjectIntrospection::Repository:0x0000000286eaa0>, Vips

Did you use the latest gobject-introspection gem? I used
gobject-introspection 2.2.4 gem:

--
% gem list gobject-introspection
*** LOCAL GEMS ***

gobject-introspection (2.2.4)

Where is the "error" variable definition?
Did you run the code?

Thanks for your report.
I'm not sure "-l" option is needed or not but I've added it
at mater.

[ruby-gnome2-devel-en] Rakefile gem:install options

[Detlef R. <det...@gm...>]

Hi,

I think that the rake gem:install task is missing the -l option, so that
the local gem - that may be modified - gets installed. What do you think?

Cheers, detlef
