Gdk::GC

Desktop Ruby-Gnome 2
1

I just installed Ruby-gnome2-0.18.0, and I attempted to run a program I
was writing, which uses a Gdk::GC, and the program returned an error:
“uninitialized constant Gdk::GC”. Now, this worked in previous
versions, and according to the documentation, I do believe this object
is still used.

I used the Gdk::Drawable#draw_line function with it to draw a little
over 50 lines, as it seems faster than using Cairo.

I’m sorry. That is a Ruby/GTK2’s bug. It’d been fixed in
trunk.

Here is a patch:

Hmm, this problem will probably break many of non trivial rg2 programs

  • for example, it breaks mine (booh). Is it not as important as the
    memoryleak of 0.17.0 hence deserves a new release quite soon?

Does it deserve a new autotest file?

cat gtk/test/test_gdk_gc.rb

class TestGdkGC < Test::Unit::TestCase
include GtkTestUtils

def test_constant
assert_nothing_raised do
foo = Gdk::GC::LINE_ON_OFF_DASH
end
end

I’ll be busy in the next weekend.
I’ll release in the first weekend of November.

I hope someone helps our release work.

Please add.

I propose something to increase release quality: when you are ready
for a new release, release it
as as release candidate, something like 0.19.0rc1, and tell in this
list (or in a new dedicated list) that
all people writing rg2 applications do test again their application.
After one week, for example, we can
release 0.19.0 if no problems were reported. Hopefully, it might help
isolating regressions (but it needs
not to become months of delay as release candidate as 0.17.0 this
summer!).

That makes me think: why not adding a new page “rg2 applications” on
rg2 website, linking to all rg2
applications? It might help publicize rg2 because we see it’s actually
used for real programs!

We will use odd release number as development release from
the next 0.19.x release. OK?

If you can maintain the list, you can crate a page for that
in the Hiki.

Maybe it could be linked also from the left menu bar? It is something
that could be good for “large/immediate” exposure on frontpage.

I think this is really a cool idea. I am reading “fantasdic’s” source
code right now to find out how he got the information viewed from
dict.leo.org :slight_smile: in other words it helps to learn ruby-gnome too in my
opinion.

Why not, though I think it will not improve release quality, as my
proposal could. For example, 0.18.1 maybe has some more important bug.
Developers don’t always test their applications with latest HEAD
code…

I can do that. I’ve created the page and listed in the Contents
section of the Frontpage

http://ruby-gnome2.sourceforge.jp/hiki.cgi?Applications

I’ll post a new message to collect the applications list.

style releasing. Did I misunderstand what you mean…?
Ah, ok. I assumed it would be like Linux, e.g. a series of 0.19.x of
unstable quality, then a series of 0.20.x of stable quality - e.g.
0.20.0 then 0.20.1 then 0.20.2. My point with in that situation, it is
not good for testing 0.20.2 and avoiding regressions.

If there is always a 0.19.x before 0.20.x, then your proposal is good, I
agree!

We don’t have a space for ‘rcX’. (We only have
RBGLIB_{MAJOR,MINOR,MICRO}_VERSION.)

            For example, 0.18.1 maybe has some more important bug.

Developers don’t always test their applications with latest HEAD
code…

I couldn’t understand why RC style releasing can fix the
problem but odd release number as development releasing
(GTK+'s release style) cannot fix the problem.

 stable release: 0.18.0 -> 0.18.1 -> ............. -> 0.20.0

development release: 0.19.0 → 0.19.1 → … → 0.19.x ^
trunk: ^ …^ …^…^ …

I think if we say “0.19.x will be 0.20.0 if no problem” in
0.19.x release announce, we will get same benefit of RC
style releasing. Did I misunderstand what you mean…?
