⚠️ Eclipse versioning issues #1036

Phillipus · 2024-03-19T16:47:54Z

This issue is to track problems with using different versions of Eclipse.

Background

Archi is built upon the Eclipse framework
There is a new version of Eclipse every 3 months - March, June, September and December
As of today, Archi is built upon Eclipse 4.28 (June 2023)
At times we need to use the latest, or later, version of Eclipse because there are important bug fixes and improvements
If we don't use these later versions, Archi might no longer work properly on certain Operating Systems, especially Mac and Linux (see this issue for a potential showstopper on Mac)
However, it seems that for each bug fixed in Eclipse, a new one appears

So the problem is what are pros and cons of each new Eclipse version?

Phillipus · 2024-03-19T16:55:54Z

The following is a list of Eclipse updates and what is fixed and what is broken for Archi. These Eclipse builds contain other fixes and improvements, but I've just listed the ones that affect Archi most obviously.

Eclipse 4.29 (September 2023)

No notable fixes or new features in this version that I'm aware of so no point in using this version.

Eclipse 4.30 (December 2023)

✅ Fixes line dash spacing bug on Windows at 200% scale
❌ Tree text is clipped on Mac Intel

Eclipse 4.31 (March 2024)

✅ (Fixes from previous versions)
✅ Fixes flipped splash screen image on Mac
❌ Table/Tree/List row heights are bigger on Mac with no option for smaller heights

Eclipse 4.32 (June 2024)

✅ (Fixes from previous versions)
✅ Option to use small or large row heights on Mac
✅ Fixes potential showstopper on Mac
❓ Regressions/bugs possible but not known yet

Phillipus · 2024-03-19T17:46:15Z

I had intended to use Eclipse 4.31 for Archi 5.3 (and had even created an early access build with it) but because of the Table/Tree/List row heights are bigger on Mac with no option for smaller heights problem reverted back to Eclipse 4.28. Let's pray that Eclipse 4.32 in June is the one.

Note that it's mainly problems in Mac that stop us moving forward to the latest version of Eclipse.

Side note - it's becoming increasingly difficult to work with Eclipse with its daily regressions, breaking changes and arbitrary change for the sake of change. Every day brings a new headache.

Phillipus · 2024-04-25T08:02:15Z

Possible danger here - eclipse-platform/eclipse.platform.swt#1064

noxxious · 2024-05-18T16:53:57Z

Another one, I just spent couple of days figuring out (Linux):

SWT relies on gdk-pixbuf to load images on Linux
The most recent change in gdk-pixbuf by default disables a set of loaders (like bmp, xpm) gdk-pixbuf#
e052a112
This requires the Linux distributions to update their builds to specifically include bmp loaders (which was no by default before the change).
With the GEF version on Archi right now that fails the basic loading of cursors SharedCursors.java, which breaks all tools in Archi as the createCursor does not allow creating with the mask set to null. The latest GEF avoids this by using png files.
Can be verified with running Archi on unstable NixOS out of the box.

noxxious · 2024-05-18T16:57:27Z

I've verified the fix by rebuilding Archi with latest night Eclipse and latest GEF (reverted Archi's changes to GEF, Zest and Draw2d)

Phillipus · 2024-05-18T17:01:11Z

With the GEF version on Archi right now that fails the basic loading of cursors SharedCursors.java, which breaks all tools in Archi as the createCursor does not allow creating with the mask set to null. The latest GEF avoids this by using png files.

Archi doesn't use the GEF SharedCursors we are using PNG images in customised cursors:

Phillipus · 2024-05-18T17:14:44Z

@noxxious OK, perhaps even if Archi is not using the shared cursors perhaps it is failing to load them. I'll replace Archi's SharedCursors code with the latest from GEF.

noxxious · 2024-05-18T17:21:11Z

It's due to SharedCursors static resources being loaded upon init (clicking in the toolbox) of any Archi's tools. Here's the stacktrace and I've added some logging as I thought initially this was due to scaling on Wayland. For the mask file (bmp) the getImageData() returns null due to missing loader and SWT exception being thrown in the method itself.

I could test right away, but how big and invasive are GEF changes in Archi ?

- Use latest SharedCursors from GEF - Load PNGs for cursors - Fixes failure to load on Linux - see #1036 (comment)

I've pushed a fix - 8c6906f

noxxious · 2024-05-18T18:44:33Z

It, works thanks. The loading of splash screen is broken due to it being an XPM, but that is not a big deal. Anyway, if you need help with upgrades to Eclipse I would like to contribute.

The loading of splash screen is broken due to it being an XPM, but that is not a big deal.

The splash screen is a BMP. But I just pushed a new commit to change it to PNG.

The app icon is XPM - https://github.com/archimatetool/archi/blob/master/com.archimatetool.editor.product/icons/icon.xpm - and this is the format that Eclipse requires.

Anyway, if you need help with upgrades to Eclipse I would like to contribute.

Thanks!
