I think this happens because/when DebugSession::handleVersion() is called with an empty QStringList argument. Why that would happen I have no idea, possible it's related to commit 102f673c6ff1afe5b1ca9cb6faa0503663b96e16 ("LLDB plugin: check LLDB version rather than lldb-mi version, which doesn't change frequently"). If that does what I think it does it tries to invoke lldb, which may not be in the path. Either way, returning early from handleVersion() works around the crash and allows the debugger to function: ``` diff --git a/debuggers/lldb/debugsession.cpp b/debuggers/lldb/debugsession.cpp index 448d3ea..e4e5c22 100644 --- a/debuggers/lldb/debugsession.cpp +++ b/debuggers/lldb/debugsession.cpp @@ -381,6 +381,10 @@ void DebugSession::handleCoreFile(const QStringList &s) void DebugSession::handleVersion(const QStringList& s) { + if (s.isEmpty()) { + // silently do nothing if s is empty + return; + } qCDebug(DEBUGGERLLDB) << s.first(); QRegularExpression rx("^lldb version: (\\d+).(\\d+).(\\d+)\\b", QRegularExpression::MultilineOption); ```
The 'version' command is issued after lldb-mi has already been started. And commit 102f673c6ff1afe5b1ca9cb6faa0503663b96e16 was intended to fix the previous way to check version (invoking lldb-mi directly which might not be in path). Strange enough, the output shouldn't be empty. Did you applied this patch? https://llvm.org/bugs/show_bug.cgi?id=28026 Could you do the following and paste the output here? 1. lldb-mi --versionLong 2. lldb-mi and then type version The output should be something like $ lldb-mi --versionLong LLDB Machine Interface Driver (MI) All rights reserved Version: 1.0.0.9 Version: GNU gdb (GDB) 7.4 (This is a MI stub on top of LLDB and not GDB) All rights reserved. $ lldb-mi (gdb) version ~"lldb version 4.0.0 ( http://llvm.org/svn/llvm-project/lldb/trunk revision 279424 clang revision 279424 llvm revision 279424)\n" ^done (gdb) Thank you for trying this out ;)

Okay, that patch is required, otherwise lldb-mi doesn't produce correct spec confirming output. That's why handleVersion is getting empty lists. And the version output is quite different, is that what you get on OS X? Seems I still need to find a more robust way to detect lldb version.
With the patch I get > lldb-mi-mp-3.9 (gdb) version ~"lldb-360.99.0\n" ^done (gdb) A year or two ago I asked about using the lldb-mi driver, on the lldb mailing list. I was told that the really clever thing to do for integrating lldb into an IDE (or writing a UI for it) would be to use liblldb directly
One more thought: I don't think you can expect that every user will have a patched lldb-mi anytime soon, so I'd advise to add a workaround like the one I posted. I don't really see any other way how you could handle the situation, other than falling back to using the commandline argument. You could post a warning that the lldb version cannot be verified, but that should be a warning that can be set to "don't show again". There's one alternative though: check the command *name*. It's quite common that the clang drivers have at least the branch in their name (3.9 in my case).
Created attachment 101057 [details] Fix Bug 268603, warn the user about unsupported lldb version I'm not sure it's a good idea to direct link to liblldb (I'm not aware any major IDE doing that). And building yet another proxy executable from scratch would be reinventing the wheel compared to lldb-mi, which is exactly a proxy already. Anyway, there's the first attempt to fix this bug, the patch does the following: - warn the user about unsupported lldb version - reject user command if an unsupported version is found (to prevent crash on invalid message) Could you try if this works for you? But I have no idea how to make the warning with an option to "Don't show it again". I suppose there should be some library function that I should call. Do you know any warnings shown by KDevelop already has this feature? Maybe I can look at that code to see how to implement this.
Oops, it should be Bug 368603 in the description of the attachment.
Created attachment 101058 [details] Add the option "Don't ask again" to warning dialog Okay, here's the one with option "Don't ask again". Currently KDevelop doesn't provide a way to reset these warnings. So you can't change your answer afterwards.
I'll try tomorrow, but how do you handle the case where you cannot determine the version of a perfectly acceptable lldb-mi? Again, the user may not have much choice to install a patched lldb-mi (think users on OS X). As to using liblldb: this *is* the preferred way to write a GUI for lldb. Pretty sure it's how Xcode interfaces to the debugger; there's also a (commercial) GUI for lldb that almost certainly does the same thing. Let's be honest, it's the most direct way to control the debugger; rather than figuring out how to control an existing driver that's tailored for another kind of application you send exactly the commands you want, without having to parse text replies which may not be perfectly adequate for what you want. Best you can do in this aspect is ask on the lldb ML, to get an uptodate opinion and hopefuly also some feedback on how lldb-mi is perceived. When I asked I got a strong impression it was seen as a 2nd-class citizen that existed only for Eclipse and that would likely never evolve towards a full MI implementation.

It starts, but then "drops out of" the debugging view, back into the code view. Any ideas?
Sorry for the delay. I don't have enough time to do any actual coding due to my course work for a few days. That looks good to me. The reason I didn't add the check for OS X was I can't find the mapping between Linux version string and OS X version string. the lldb plugin on Linux didn't work for you after applied my latest patch? Is it the case that you clicked 'don't ask again' and answered no? There should be some output in the Debug output panel saying that session stopped due to unsupported lldb version.

No, I didn't tick the "don't ask again option". I checked with an unpatched lldb 3.8.1 on OS X and I indeed got the warning in the debugger console, but IIRC everything else was functional. No, on Linux I get something else: it looks like the debug session is being created as expected, and then the IDE falls back into the regular code view. Which means I cannot even get at the debugger console to check for any relevant output there.
Could you start KDevelop from the console and check the output when starting the debug session on Linux? You can enable debug output from KDevelop by launching it with the command env QT_LOGGING_CONF='logging.conf' kdevelop where the content of logging.conf is [Rules] kdevelop.debuggers.lldb.debug=true kdevelop.debuggers.common.debug=true Also, even if the debug session ends, there should be an output panel titled "Debug" being raised. See if there's any relevant output in that.
Thanks, but I just found the reason when I tried a manual debugging session. Turns out it's more a bug in the lldb-3.9 package: it doesn't install non-versioned binaries, but it wants an lldb-server executable. That also explains why it worked before (when I still had a working ll**-3.8 install) and no longer after I upgraded to 3.9.0 . I noticed the issue just too long after that upgrade so I didn't make the link (mental link, not symlink) :-/
I'm glad you found the reason. So the patch itself works for you now? If so, I'm going to close this and push the change to master.
Yes, at least as far as starting with a break in main goes. I didn't go much beyond testing that; lldb-mi-3.9 took so much memory when I tried with a simple Qt5 app that my whole plasma4 environment was OOM'ed. One detail though: is a patched lldb-mi required for the correct change of working directory? Because that detail doesn't work with the lldb plugin on Linux even though the debug output suggests it does.
Pushed to master with commit 262bf5dddf2aef991c66fdc484c58daf32eaa348, so I'm going to close this, reopen it if you have any further problems. A debugger shouldn't take too much memory. It looks like a bug. Did you try to manually debug using lldb 3.9? And please open another report if that only happens in KDevelop. Well, the working directory changing does require another patch[1] ... And I've created a RR in their Phabricator[2], which seems to be more active than their bug tracker.

I'd have to figure out how to start a debugging session in lldb-mi manually, in order to check this correctly :) But: did you ever notice how starting the debugger on a C++ app using KDE or Qt takes so much longer than starting it on a simple C app? That's because it has to scan through many more libraries containing many more and considerably more complex types. Maybe not all that scanned information is cached, but a good part is. It seems a bit weird that it would let the process image reach 6Gb but then there are so many different kinds of memory footprint nowadays, some of which are purely virtual (with overcommit and all) that I don't trust myself to notice the one that corresponds to actual memory use when the system is being trashed. FWIW, I've the kernel overcommit parameter set to 2 on my system, but that shouldn't affect the amount of memories applications request nor increase the amount they actually get.
For a simplest session: $ lldb-mi /path/to/executable -break-insert main.cpp:30 -exec-run There are also commands like -exec-continue, -exec-next. Reference: https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Program-Execution.html#GDB_002fMI-Program-Execution I don't have enough knowledge about how actually a debugger scans app's memory space or the overcommit thing. But my intuition is, just attaching a debugger to the app shouldn't dramatically increases its memory usage... AFAIK, starting a complex app in debugger takes longer simply because the program is being instrumented and thus runs much slower.
