thanks, applied to 5.4

done now, thanks a lot!

I'll commit this using QFileInfo instead of going through QDir.

Scrapping this for now, since I have a few improvements on this, but it needs to be reworked. Ill make a PR with updated version on GitLab instance.

I would like to get this merged in if possible. The work discussed for flushing out future deadlocks should also be done, but deserves its own ticket.

Thanks @kossebau for the review. I will create a review request at the kirigami repo.

I would propose though to add this template to the kirigami repo though, so it is also available to people using the kapptemplate tool and using a plain text editor (e.g. Kate).
There is the ECM macro kde_package_app_templates from https://api.kde.org/ecm/kde-module/KDEPackageAppTemplates.html for this purpose.

Given the big KDevelop & Kate share plugins stuff never took off, I think we shall keep them just in kate.git, this will allow to do even more "experimental" stuff in the future like having some extra interfaces for Kate specific stuff that doesn't need to keep BC.

• outputfilteringstrategies: Removed unused include KDir

• Created private implementation of ScriptErrorFilterStrategy
• executescript: fix setting working directory to OutputView

The reason there is weird. When you press "launch" on the software center you expect to get the IDE, not an empty list of sessions.

This patch looks like it should work as intended to me :)

From what I understood, this is effectless, as _ps is referenced by <launchable>. We need to check with @mak here.

Yep, according to @mak, this should work.

Great! You can Abandon this revision from the Add Action... menu above the comment field if you'd like (you can always re-open it later if need be).

What you're objecting do is actually just the way menu section headers look in the Breeze widget style. I agree that it causes confusion and visual problems, but it should be fixed there, not here in KDevelop.

Here's the applicable Breeze code that draws these headers https://cgit.kde.org/breeze.git/tree/kstyle/breezestyle.cpp#n4741

Would you like to have a go at improving it there?

I will look into it next week. The used icon is bogus. I was hoping for some input on that :) But i liked the idea of an icon in general.

Maybe it would make sense to move the whole dialog into git plugin's code.

I created some screenshots. Icon ist in the line edit (near the mouse pointer in the first picture).

I hope it is ok to add you as reviewer directly as you orchestrated the last commit from me in this area.

I have been mega busy for the last while and intend to contribute more to this project when my situation stabilizes in like two weeks. Whenever you have time, I would definitely be interested to hear what sort of challenges you have come across through experimentation. An issue which I have suspected from the onset is actually determining all that needs to be protected by DUChain's lock and those which don't since KDevelop source makes use of these locks so liberally. I'm wondering if in your experimentation there are open questions about the DUChain locking scope.

Work-around pushed as 8a18a08cf17c85000c7082d5192855430a519bab , seems to pass build also with neon ci and the gcc 7.4.0 there.

Seems the introduced QStringLiteral as default argument here in the template method executeCompletionTest() makes ubuntu bionic's GNU 7.4.0 C++ compiler screw up. At least there is some timely coincidence that the KDevelop builds on neon CI started to fail after this commit, with this error:

I do not think bumping versions "just because " has any value.

I kind of agree here. Unless we have features that we know are only available with a certain version, we might needlessly restrict how people can build this. They might assume we have a good reason for choosing that specific version and that older versions can't possibly work. When I package stuff for openSUSE, I would never try decreasing minimum versions of dependencies, because I assume that these are actually the minimum. On the other hand, I regularly stumble across software that doesn't specify minimum versions for dependencies, but assumes it's "reasonably recent".

Also, in spite of what I said earlier, I think the explicit DUChain locking should be done and there eventually should be some work done to determine which objects will only interact with one specific DUChain per instance of that object, i.e. an object that should reference a specific DUChain, e.g. ClangSupport. We could make the first pass at this involve replacing all of those DUChainReadLocker lock; lines with DUChainReaderLocker lock(DUChain::lock());, [...]

Overall I think this is a good idea, although we need to figure out some details. Could you either remove commented out flags or add a comment why we have them (commented out)?

I don't know what would be required to support multiple DUChains, but it seems plausible that they can be locked separately. In this case it would help to have the explicit argument, I guess. It could even be inevitable, when there is no single global DUChain anymore.

Can we have a test for this?

There is another condition here: `if (lastShownMenu)`. So if the QMenu object instance got deleted

Add rtti flags since they affect defines.

Prefer not duplicating code.

Just do the simple thing. Copied the one line of code due to
the awkwardness of preprocessor directives inside template lists.

As the person who raised the Debian Stretch issue last time, I don't think it's worth caring about now that Buster is released.

Sorry for my conservative thinking again: Debian Buster (10) is still /very/ fresh; it was just released a couple days ago. The former "oldest" supported distro was Debian Stretch (9) with Qt 5.7 and KF 5.28. That'll stick around for some time.

(Using phabricator to make sure people are triggered for this central change)

I'll activate the debug trace on change of my lastShownMenu though

I'm doing this (in my patch from D16882 which still applies after reverting D22424):

+        if (menu != lastShownMenu.data()) {
+            if (lastShownMenu) {
+                qCWarning(SHELL) << "Added items to new contextmenu" << menu;
+            }
+            lastShownMenu = menu;
+        }

under the assumption that this will print a warning (enabled in qtlogging.ini) when lastShownMenu will be updated but not the 1st time a ctx menu is opened. Is that assumption wrong, because I'm not seeing any warnings after disabling the CTags menu (and restarting KDevelop for good measure).

I'll activate the debug trace on change of my lastShownMenu though

In any case there isn't much else you can do; stepping through the code with a debugger is near impossible (the menu about-to-be-opened will already have grabbed mouse and keyboard focus so you'd need to display remotely).

Please add a line

to KDevelop::TextDocument::populateContextMenu.

The context menu is queried every time from KXMLGUI that method is called.  So  if KXMLGUI internally decides to recreate the context menu, you get another object the next time. Please see again the description of this very bug.

Erm, aren't you forgetting about my patch which could have been applied to the (EOL!) 5.3 branch? That does the job just as well and would have left time to find a fix for #409858 in time for the next release.

I fail to see an immediate reason for this, so I'm back to running my own patch.

Interesting. Not seen here, but giving this some stress testing now. The kdevelop_xxxxx.patch is coming from the diff review system creating text document objects for displaying the diffs, but I also see no direct relation ship to this patch here. Will poke around a bit,

update to first review feedback

Thanks for first review & testing.
