I've now seen two cases where KDevelop crashes, DrKonqi starts but doesn't get any backtrace at all and all the usable information I get from the terminal is ``` KCrash: Application 'kdevelop' crashing... KCrash: Attempting to start /opt/local/lib/x86_64-linux-gnu/libexec/drkonqi from kdeinit sock_file=/run/user/505/kdeinit5__0 QSocketNotifier: Invalid socket 9 and type 'Read', disabling... QSocketNotifier: Invalid socket 28 and type 'Read', disabling... LIBCLANG FATAL ERROR: IO failure on output stream: Bad file descriptor Unable to start Dr. Konqi Re-raising signal for core dump handling. ``` Both times happened while parsing a session containing a project for the KDevelop source tree that had not yet been opened with the current git head of the 5.3 branch (v5.3.0-37-ge1a51bd359). Both times I restarted the process, attached a debugger and did not get the bug again. I'll update this ticket as/when I learn more.
Another comparable crash where the process was killed before DrKonqi could get a backtrace (= while it was trying to?). This time libclang printed a bit more: see below. I was in patchreview mode, and had just saved some more changes to a file. I have noticed before that the clang parser and the patchreview mode don't really like each other (sluggish performance). ``` git diff job: ("git", "diff", "--no-color", "--no-ext-diff",

FWIW: Qt Creator appears to be using a server process to deploy its clang-based parser. I don't know at what overhead cost that comes with, but I think there are a few obvious advantages to the approach: - crash-protection: just restart the server if libclang runs into a problem (i.e. when the server is no longer there). - RAM use and management: multiple sessions can connect to a single server process and (in its simplest form) memory can be reclaimed by restarting that process manually. If this hasn't been considered yet (and is anyway feasible) it could make for a very nice GSoC project.
From my point of view that is unfortunately not feasible. It would be very good to have it, but too hard to do.
Pity. Any idea how Qt Creator can pull it off then?
Different overall architecture :/
Or maybe they just designed the parser around a server architecture instead of using lots of direct calls into libclang? I haven't even tried to understand how the current architecture is designed. But if the issue is "lots of direct calls into libclang", can't you write a (set of) wrapper class(es) that hide the server/client details and that provide bindings for all used functions (it might be possible to generate many of those automatically)? Lots of work but not necessarily very difficult, probably not more so than designing the server/client protocol itself.
Feel free to try and devise a strategy how this should work. I thought about it for a few hours and couldn't come up with anything remotely feasible.
I will, though don't hold your breath I'll do better than someone who's bound to know this part of the code a lot better than I do. The only brain fart I had for now is how Objective C's support for sending messages (= calling class methods) to remote class instances could have come in handy here. But that is something I never actually used. Anyway, there's a reason why I suggested a GSoC project ;)
I think this is out of scope for a GSoC project, a newcomer will not obtain the necessary understanding for doing this within 3 months.
Wow, is the architecture that complex or opaque (on top of the already not very accessible libclang API itself)? If so we should hope nothing ever breaks when the original author(s) are unavailable...
Well, you have been around for years and you have continuously been claiming it is too complex for you to look into, so there's that ;)
Well, I've never made such claims under the premise of spending 3 months on it full-time (with or without the additional detail of a formal training in computer science) O:-) And in another there's that register: there's a Murphy's Law version predicting that if I do let myself get dragged down this hole and IF I manage to come up with something that works it will by definition be the least acceptable solution ;)
Created attachment 116733 [details] New crash information added by DrKonqi kdevelop (5.3.0-38-g7898bb4174) using Qt 5.9.7 Here's a crash where I did manage to get a backtrace (but is it useful...?) I'd been editing files selected via the search-in-files toolview and was opening a next file, in which the crash happened. This project had already seen a full build but yet the parser claimed it couldn't find most headerfiles (at least not after adding that full build directory to the cmake project settings).

Now this is extra interesting: after sending off my previous comment and quitting DrKonqi, the crashed KDevelop made a more or less clean exit, judging from terminal output.
