Application: kdevelop (4.3.90) <-- thats old, could you please update to recent master and see whether the crash persists?

Tried again with 4.4.1, same crash.

Do you see anything on the CLI that indicates odd behavior? Esp. this output:

#8  0x00007f36ebe3a39e in __libc_message (do_abort=2, fmt=0x7f36ebf41e5f "*** %s ***: %s terminated\n") at ../sysdeps/unix/sysv/linux/libc_fatal.c:201

With the arguments substituted should be interesting. Also please enable the KDevplatform (external scrip) debug area in kdebugdialog to see which command it tries to execute in which directory.

cheers

I enabled KDevplaftorm (External script) debug in kdebugdialog and KDevelop started fine (took a long time). After that, I tried 4 times (2 times with debugging, 2 times without) and it didn't crash. I will keep an eye on it but maybe it was caused by some saved state which now got overwritten.

One more thing: it appeared while populating "Projects" view with the file tree before anything was shown there. Once you got files shown there and progress bar in lower right corner showing something (blue column moving left-right), it works fine.

OK, please provide the information above once you can reproduce it. Thanks

actually this might be a duplicate of bug 306908

I've just ran a session from the console using "kdevelop --ps" that is crashing atm. I've pasted the out to the bottom of this comment.

I noticed it is complaining about being able to add paths to files that I can confirm are there. Also of interest is near the end where it says 'Could not open file "/usr/share/kde4/apps/kdevphpsupport/phpfunctions.php"'. I can confirm this file does exist and upon a quick inspection, looks correct.

I have another Kdevelop project open and am running a couple of activities. One of them had a lot of Chrome browser windows open with lots of tabs. Those windows have all been closed before this and Chrome restarted but do you think this could be a number of open inodes limitation as both Kdevelop session have a quite a lot of open files (about 40 each). Its probably worth mentioning that these are PHP projects (Drupal infact).

lsof -a -p $(pidof kdevelop) | grep REG | wc -l
358

Now if I edit a C++ file I start to load the topducontext files:

$ lsof -a -p $(pidof kdevelop) | grep REG | wc -l
405

I.e. the files stored in $HOME/.cache/kdevduchain/$SESSIONID/topcontexts/ - which can be quite a few...

Can you try to increase /proc/sys/fs/file-max and see whether that work-arounds the issue of the crash? If so, we should try to refactor the code to reduce the number of file descriptors required... Not an easy task probably.

@Milian Wolff FYI I posted responses on bug #306908.

When I do: "lsof -a -p $(pidof kdevelop) | wc -l" I get:
lsof: status error on 6287: No such file or directory
lsof: status error on 6197: No such file or directory
lsof: status error on 6124: No such file or directory

Any idea why that is? If I can get this bit of info going I'll try and keep an eye on the count and watch for a crash. Then I'll up my file-max limit.

BTW if I am running out of file descriptors would I not start seeing problems with other applications? I tend to have a lot of browser windows and tabs open and I would think if I open more when I start seeing these problems that the browser would start to freak?

Ah, you seem to have a lot of KDevelop processes running. That would indicate the error of bug 274246 - which is probably related. As I said above, please do this:

"Also please enable the KDevplatform (external scrip) debug area in kdebugdialog to see which command it tries to execute in which directory."

This should give us a hint at what process we fail to execute and then leak.

You are correct. I had multiple Kdevelop sessions running to stress test things. With one open I can run the lsof command.

$ lsof -a -p $(pidof kdevelop) | wc -l
464

$ lsof -a -p $(pidof kdevelop) | grep REG | wc -l
432

After editing one PHP file by adding the following:
  $var = 'testing';
  drupal_set_message($var);

$ lsof -a -p $(pidof kdevelop) | grep REG | wc -l
1254

So a big increase. I have the "KDevplatform (external scrip)" enabled in kdebugdialog now. Does that produce extra output in the console that I need to keep an eye on or improves the backtrace output?

Just got a crash on firing up a second existing session. Not that I had re-enable a few kded services:
* Input actions
*Keyboad Deamon
* Removable device Automounter

Anyway I had created a simple logger to keep an eye on the file count from "lsof -a -p $(pidof kdevelop) | grep REG | wc -l". FYI the crash happen at 19:10 (And note I still have the first running):

Hope you find that helpful?

So here is a bit of into you might find useful. After that last crash I upped my ulimit from 2048 to 4000 and KDevelop started just fine. I closed it and started again and still fine. Changed my ulimit back to 2048 and bam! Crashed right after startup again. I suppose that definitley confirms the inode/file-descriptor issue on my setup?

FYI for anyone who wants a possible temp workaround. Try upping your ulimit with the following:
$ ulimit -Sn 4000
And start Kdevelop from the same console (it will only apply to that running console session). So you could just enter the following in Konsole or krunner:
$ ulimit -Sn 4000 && kdevelop --ps
Note that the max number you can set that to is defined in /etc/security/limits.conf and can be viewed with:
$ ulimit -Hn
On Ubuntu this seems to be set to 4096 by default. If you want higher you will have to set the hard limit in limits.conf.

Ok that session soon crashed even with "ulimit -Sn 4000 && kdevelop" with the following showing in the terminal:
File size limit exceeded (core dumped)
BTW it did not create a debug window with the backtrace. Does "core dumped" mean some log was saved somewhere?

This is related to the kded4 crash, but probably not a duplicate, unless kdevelop and a kded4 module use the same code somewhere (e.g. Nepomuk, or whatever).

Is there a workaround for the time being? I've already ran with kded4 killed and with a bare minimal set of modules and still get the crash. The only answer seems to be restart the system and it will work for a while.

I have it again 100% reproducable with "KDevplatform (External Script)" checked in kdebugdialog. The backtrace looks the same (QProcessPrivate::waitForStarted()). What additional info should I include?

From the console log, it seems that "Too many open files" is the problem:

Sorry Christoph, I didn't mean it was the "same" bug as in from the same code base, just the same issue at the core which leads to similar crashes.

Sasa, your last output shows a potential issue and I'll investigate that. Thanks.

This simple test file leaks file descriptors:

#include <QtCore/QCoreApplication>
#include <QtCore/QProcess>

int main(int argc, char** argv)
{
  QCoreApplication app(argc, argv);

  for(int i = 0; i < 1000000; ++i) {
    QProcess p;
    p.start(" - garbage - ");
    p.waitForFinished();
  }
  return 0;
}

As a workaround we'll probably have to verify the argument of every QProcess in our code base for now. I hope it might also be fixed upstream somehow though.

Upstream bug report: https://bugreports.qt-project.org/browse/QTBUG-27945

@Milian Wolff I see in that bug report you linked to that the problem seems to stem from trying to execute binaries that are not there. Is it possible to find out what binaries KDevelop is making calls to that do not exist and then either disable the offending plugin or add a dummy executable file (e.g. something that just returns) just to satisfy Qt so that it does not leak a file descriptor?

Wherever that comes from:

kdevelop(31234)/KDevplatform (External Script) ExternalScriptPlugin::executeCommandSync: executing command  "if ! [ -e /home/kara/.kde/share/apps/kdevelop/sessions//{4bb5b064-54e6-425c-8480-053fde7fe8d3}/default.sh ]; then touch /home/kara/.kde/share/apps/kdevelop/sessions//{4bb5b064-54e6-425c-8480-053fde7fe8d3}/default.sh; fi"  in working-dir  "/home/kara/projects/CoreLib/Skyper/utils/BuildLib"

It's being called over DBus so I'm not sure where it comes from. Maybe just disable the external script plugin...

I changed the sessionrc file in ~/.kde/share/apps/kdevelop/sessions/* to:
kdevexecutescriptEnabled=false
kdevexternalscriptEnabled=false

Then I still got a crash:

The <path> string was a full path to a file which existed and was readable for me.

Not sure if it's still the same problem I am hitting but KDevelop is still reliably crashing at startup but output is different:

One thing I had is relative paths in .kdev_include_paths (content was ".\n..") but it still crashes after I renamed the .kdev_include_paths files.

*** Bug 314522 has been marked as a duplicate of this bug. ***

in my work I use Ubuntu in which the bug reproduces, at my home I use Gentoo which doesn't reproduces, wouldn't it be more easy to pinpoint the issue on which pkg it happens on in Ubuntu and open a bug on this at Ubuntu?

it seams that latest kdevelop/kdeplatform from git + background parser doesn't crashes the system.

I've also removed all config files so this might be related.

correction, background parser disabled

Git commit 6d5e7608c5b4fe675fb42e9467e7f1acc3395b8b by Milian Wolff.
Committed on 13/02/2013 at 23:35.
Pushed by mwolff into branch 'master'.

Increase the item repository version.

I think that I might have introduced an incompatiblity in the
recent changes to e.g. the SetDataRepository. This in turn then
resulted in strange crashes on startup like shown in bug 314031.

Lets keep that open for now but I think these crashes on startup in
KDevelop::ItemRepositoryRegistry::registerRepository should now be
resolved...

http://commits.kde.org/kdevplatform/6d5e7608c5b4fe675fb42e9467e7f1acc3395b8b

this commit made it worst, now I cannot even use kdevelop with parser off, it just crashes when I click a c or header file in the projects dock without even getting a crash report screen.

I get this when I run it:
(process:10983): GLib-ERROR **: Creating pipes for GWakeup: Too many open files

10983 Trace/breakpoint trap   (core dumped) kdevelop

yesterday's git update seems to solve the issue.

thanks to the devs for solving this.

seems to be fixed
