Plenty of bugs: any debug mode available?

[LAHAYE Olivier]

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,
