Description Alexey Morozov 2016-09-22 07:04:35 UTC

Application: kdevelop (5.0.1)

Qt Version: 5.7.0
Frameworks Version: 5.26.0
Operating System: Linux 4.7.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I have a rather big and complex project containing C++, JS and (a few) Python files. JS is a Dojo-based web-application. KDevelop crashes while loading and parsing the project. If I remove the JS part, loading process finishes successfully. I've tried to remove caches, completely remove KDevelop configuration and so on.

- Custom settings of the application:

None I am aware.

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Comment 1 Kevin Funk 2016-09-22 09:04:21 UTC

Are you simply running out of memory? Is the project public, so we can try reproduce the problem ourselves?

Comment 2 Alexey Morozov 2016-09-22 09:19:06 UTC

No, unlikely. I have 16Gb of RAM and 8 gigs of swap, completely unused. Most of RAM is used for file/buffer cache, according to `free -m`.

What's interesting is that removal of JS folder, loading the crippled project into KDevelop and subsquent restoration of the folder with JS files solves the problem: on the second run KDevelop discovers the new folder, and successfully indexes JS files in it.

But nevertheless, there's plenty of RAM available, and nothing points to out of memory errors (no swapping, no log messages from OOM killer, nothing). It could be a problem with some other limits though. The project contains 1751 С++ files and headers, and almost 13K of various JS files (mostly came from the framework/libraries).

    core file size          (blocks, -c) unlimited
    data seg size           (kbytes, -d) unlimited
    scheduling priority             (-e) 0
    file size               (blocks, -f) unlimited
    pending signals                 (-i) 63848
    max locked memory       (kbytes, -l) 64
    max memory size         (kbytes, -m) unlimited
    open files                      (-n) 1024
    pipe size            (512 bytes, -p) 8
    POSIX message queues     (bytes, -q) 819200
    real-time priority              (-r) 0
    stack size              (kbytes, -s) 8192
    cpu time               (seconds, -t) unlimited
    max user processes              (-u) 63848
    virtual memory          (kbytes, -v) unlimited
    file locks                      (-x) unlimited

Unfortunately, the project isn't public, so I can't simply give an example.

Comment 3 Alexey Morozov 2016-09-22 10:01:53 UTC

... but certainly, I can run KDevelop under gdb and inspect variables on crash. Also I can add some traces to KDevPlatform and recompile it, just give me appropriate advices.

Comment 4 Kevin Funk 2016-09-22 10:50:27 UTC

Can you try running KDevelop under valgrind? Thanks for helping out!

valgrind --smc-check=all-non-file --track-origins=yes kdevelop ...

Comment 5 Alexey Morozov 2016-09-22 11:59:12 UTC

Started the `valgrind` process, but since it's working quite slowly (the progress indicator reports only 1% of the project have been analyzed after ~hour of work), I expect things to complete at least a day after. Please don't close the bug before :)

Comment 6 walmartshopper 2016-10-06 23:14:25 UTC

I can reproduce this but only when opening a large javascript file from a network share.  Opening the same file from a local drive is fine, but crashes when opened from a smb:// or sftp:// location.

The following file causes the crash for me:

https://raw.githubusercontent.com/Mottie/tablesorter/master/dist/js/jquery.tablesorter.combined.js

Once the file is opened, the kdevelop process starts eating up a full CPU core and consuming about 2GB of memory per second until it runs out of memory and crashes.  It got up to 20GB of memory used before crashing.

Comment 7 Sven Brauch 2016-10-15 12:34:19 UTC

*** Bug 369573 has been marked as a duplicate of this bug. ***

Comment 8 Alexey Morozov 2016-12-12 07:19:04 UTC

The problem can't be reproduced in 5.0.2+ on the same test data in the same environment (OS kernel and libs, amount of RAM etc). I guess, it was implicitly resolved during the development.

Comment 9 Kevin Funk 2016-12-12 08:03:23 UTC

Ah, interesting. This bug is probably related to bug 370495, which got resolved in 5.0.2. This is the first time we see this issue happening on Linux I think.

Thanks for the feedback!

*** This bug has been marked as a duplicate of bug 370495 ***

Comment 10 Fabian 2017-03-07 13:41:39 UTC

This still happens to me in KDevelop 5.0.4.

Comment 11 Kevin Funk 2017-03-07 13:58:17 UTC

@Fabian: Same backtrace? Please post it here.

Comment 12 Fabian 2017-03-07 14:49:54 UTC

BT when KDevelop starts consuming memory

Comment 13 Fabian 2017-03-07 14:51:37 UTC

https://bugs.kde.org/show_bug.cgi?id=369573 was my original bug report. KDevelop still crashes every time I edit a js file on a remote server with sftp://

Comment 14 Kevin Funk 2017-03-07 15:10:58 UTC

Please continue commenting on the original report.

This one here is a different issue.
