overview causes geany to crash when crating a new file and clicking in the file area.

[l33tlinuxh4x0r]

Without overview geany does not crash... when overview is enabled creating a new file in Linux X11 causes geany to crash when the file is clicked. Windows and wayland seem to be unaffected. See bug https://github.com/geany/geany/issues/2736

[elextr]

Overview plugin uses Scintilla to generate the overview, but there have been no changes to the plugin for many years, but IIRC there have been changes to Scintilla, some of which may be incompatible with such old code.

As nothing has been heard from the "maintainer" of the overview plugin its probably unlikely it will be fixed unless "somebody" does it, or the plugin is shown to be the cause of a crash it may be dropped if nobody cares for it.

[l33tlinuxh4x0r]

Fwiw I love the plugin... I just don't like the crash :/

FWIW I can confirm the crash, and got this GDB backtrace and Valgrind log:

GDB backtrace for the crash (nothing new though)

I however have for now no clue what the issue is or even where (is it Scintilla doing something problematic with multiple concurrent views, is it a timing bug in IBus or GTK?).

[b4n]

BTW, somebody motivated enough could try and find what broke this plugin, it could help debug the issue. Be it testing various Geany versions or even better, using git bisect.

@l33tlinuxh4x0r in this context "care" means "does the work to fix it", as in care and feeding, not just "like" it :grin:

If I had the skills I would fix it, however I don't so hoping that someone else will take this up.

[fmbearmf]

culprit is likely in overview/overview/overviewscintilla.c

[porter312]

Just wanted to confirm the issue with Linux Mint 22 and let you know: as a user since 2006, this will be my goodbye to Geany.

It was already weird how basic modern features like Overview (which even Mint's basic text editor has) and Split Window were not native features but 3rd party plugins, and suffered the common issue 3rd party plugins usually do: not working with each other. But now, I can't even have an Overview without opening a new tab completely crashing my IDE. I can't work with this.

Yes, I understand that you may be offended by this blunt feedback and remind me how Geany is FOSS, but at the end of the day my time isn't free either. Sorry and thanks for being great before. Maybe you'll make Geany great in the future.

[elextr]

@porter312 since your "time is not free" means your approach is to consume from others and not contribute in return you are probably better off somewhere else.

[porter312]

@elextr So financial donations and reporting issues don't count? Most developers these days have become too soft and emotional. This is why I was blunt and didn't sugar coat it, so that we would immediately get to the point. You can either be rational and accept that I in fact contributed here by wasting time having my project crash and then spending time giving free feedback here, or you can be merely offended and keep Geany in this state, the choice is yours.

I contribute a lot to society, but I have a feeling of duty even for stuff I do for free: because free work can still harm other people and I'm not absolved from any moral resposibility because I did it for free. Sadly many people don't think that way.

[elextr]

Most developers these days have become too soft and emotional.

As you appear to be from your self defence.

All I provided was agreement that a project better shaped to your needs (described quoting your words) may be found elsewhere since it is simply a fact that Geany is a low contribution totally volunteer project and nobody can be forced to spend their effort on any specific feature unless they want to.

That makes Geany clearly an inappropriate tool for you since the contributors appear to consider other features more essential of their available effort, and so not to have the available effort and/or interest for items that you consider essential.

If you can't run without an overview or some other specific feature, and nobody has contributed an implementation of the feature or a fix of an existing implementation, then you do indeed need to use a different tool or find someone to contribute fixes or new implementations of your features so you can have them.

[porter312]

You literally accused me of only consuming and not contributing, you were clearly not accepting the feedback and instead just being passive aggressive about it.

But yes, totally, "if tool can't do A and I need A then I need to use another tool". I know that without you being patronizing about it, the reason I posted was I though it was valuable to provide feedbaxk that these 3rd party plugins breaking down over the years and their features not being incorporated to othe core app causes users of 18 years to be forced to migrate.

Anyway, whatever.
