Plenty of bugs: any debug mode available?

[LAHAYE Olivier]

I think I've found the bug (my fault), though, on thing is horrible as you can do:

my_sprite.SetX=20; // No errors, but you destroy the SetX() and it is replaced with a value.
Then later, calling my_second_sprite.SetX(100); // Correct syntax will produce no error (it should!) and proiduce nothing visible as it is equivalent to 20(100); // which means nothing....


In other words:
A Method can be replaced with a simple value hiding/removing the method itself.

The problem here is that the SetX() won't work anymore even for other sprites that have been defined elswhere and before this line.
Replacing the method of a single object with a value (strange idea, but anyway...) is one thing, but in fact, replacing SetX() in one object will void it for all sprites.

So I think it's a bug IMHO.

Will test and confirm.

Cheers,

Hi Charlie,

Thanks for your fast answer.
I hope you don't mind that I reply to the list, but I think this can be of any use to someone else.

I though this list was dead since there is lots of old bugs still openned in the bugtrack and since the last commit is almost 2 years old. This is good news :)

Anyway, I don't need X11 debugging as I'm using qemu and thus it's easy to debug. My initrd has an ssh client, so I can update live my scripts without rebooting my initrd.

I have a complete testing script that simulates all the expected behaviors.

My need right now is:
- Know if there are some limitations (max number of variables? or images? or sprites?)
- Know why adding code that is not even executed disable the my_sprite.SetPosition() (or SetX....)
- Trace variables in the debug log (does a Debug.log("message") exists?)

I have no syntax errors
My log code alone is working fine
My icon code alone or with log code is working fine
My progress bar alone is working fine
If I glue all, SetPosition doesn't work anymore?!?!?!?!?!

Really puzzeling.

Hi Oliver

Have you tried debugging in x11 environment instead of doing real boots?

Hi,

I'm desperately trying to create a specific them for systemimager, a software run from a PXE initrd that will partition, format a disk and deploy an image on disk.
This theme will display current processing log (works), steps icons (works) and a progress bar for some steps (fails)
The problem is the following:
If I add the progressbar code, the SetPosition doesn't work anymore (sets position to 0,0,0)
even if I hardcode some values, it has no efffect.
If I remove the progressbar code, it works again.

My question is then: are there a maximum number of images or sprites that can be created?
log uses 15 lines (x2) = 30 sprites
logo = 1 sprite
step icons = 7 sprites
progressbar = 3 sprites

The plymouthd log is a nightmare to read as it is align=center (Why the hell this choice????)

I've even noticed that table.object.image = Image("foo.png"); is ignored while
table_object.image = Image("foo.png"); //works!!! No syntax errors, but the above is simply ignored!!!

If only the parser was written using lex+yacc or even better with an existing scripting language lightweight library like liblua or equivalent...

Aside spinning a logo, it's almost unusable and plymouthd often crash. (Fedora-25 latest updates)

Are there some settings in /etc/plymouth/plymouthd.conf that could help me?
(left aligned logs???)
(track image and sprite creations and positions in log???)

Is there some Debug.log("message") available that could send a message in plymouthd debug log?

It's very frustrating when hitting so many bugs that slow development. I even don't know if there is a way to achieve my them (in theory yes, but practically, so far, that doesn't work)
I think there is plenty of memory corruption (and plymouthd segfault proves it).

Cheers,
