Sentry Crash Report:

Description Alexander 2010-12-19 22:02:43 UTC 
Version:           SVN (using KDE 4.5.3) 
OS:                Linux

I'm using KDevelop 4.2 git branch (2010-12-19).

I have an autotools-based project (loaded in KDevelop using KDevGenericManager). If I open my file manager, create a "build" directory and run "../configure", there's a 50% chance that KDevelop crashes. I guess it's related to the fact that the configure script quickly creates / deletes lots of files.

I also tried it with kdev-custom-buildsystem, the crash is still there.

Thanks


Here's what the KDE crash handler reports:

Reproducible: Sometimes

Steps to Reproduce:
Take any autotools-based project, open it in KDevelop, run "mkdir build; cd build; ../configure". There's a fair chance KDevelop crashes.



openSUSE 11.3 x86-64, KDE 4.5.3 from OBS, Qt 4.7.1.
Comment 1 Milian Wolff 2010-12-19 22:21:33 UTC 
that is the newest git code (from git.kde.org - not gitorious)? damn, I hoped I had fixed all issues there.

Please run KDevelop through valgrind and show me the log it creates when you reproduced the crash:

valgrind --track-origins=yes --num-callers=50 kdevelop 

thanks
Comment 2 Alexander 2010-12-19 22:40:24 UTC 
Yes, it's from git.kde.org.

Here's the valgrind output (did ../configure a few times, it crashed when I removed all the files from the build directory).

Comment 3 Milian Wolff 2010-12-19 23:50:16 UTC 
ugh ugly, nothing useful shown - except that the pointer is invalid :-S

is that project FOSSn / publically available, i.e. could I try to open it myself in kdevelop and run configure like you do?
Comment 4 Alexander 2010-12-20 10:08:02 UTC 
The results above were obtained after opening this project:
http://gsmartcontrol.berlios.de/
http://prdownload.berlios.de/gsmartcontrol/gsmartcontrol-0.8.5.tar.bz2?download

There's no kdev4 project file in there, just import it choosing Generic Project Manager. Then, from the project directory, run "mkdir build; cd build; ../configure". If it doesn't crash the first time, remove the build directory and repeat.

I was able to trigger the bug with another (non-public) project of mine as well.

Thanks

Comment 9 Milian Wolff 2010-12-23 15:49:57 UTC 
alexander, please test these patches (they are in 1.2 and master branch of kdevplatform). reopen if it's still broken for you.
Comment 10 Alexander 2010-12-23 18:21:24 UTC 
Got a crash after several attempts (git 4.2 branch, 2010-12-23).

Note that after removing all files in the build directory, KDevelop's project tree still showed some of them. Not sure if it's related (should I file another bug?)

I can compile KDevelop & friends with debug support, if that helps.


Output from KDE crash handler:

Comment 16 Milian Wolff 2011-11-20 20:36:15 UTC 
Git commit 19d9907d73f342debc2654cdf044b9a48a15798c by Milian Wolff.
Committed on 20/11/2011 at 21:12.
Pushed by mwolff into branch 'master'.

fix crash when files are added/removed by external program

This could 'easily' reproduced by opening a large git-based project in
kdevelop with one of the AbstractFileManager-inheriting project
manager. Then switching between branches resulted in a crash sooner or later.

The main culprit was that FileManagerListJob::slotResult was sometimes
called after a the job was killed. KJob::kill apparently does *not*
kill the job directly, hence we need some additional safeguard here.

Furthermore this patch adds some more safety measures against invalid
item pointers in the FileManagerListJob's m_listQueue.

Please test!

Comment 17 Milian Wolff 2011-11-23 13:15:20 UTC 
reopening, can still happen when e.g. opening an in-source build of Qt in kdevelop and then calling: "make clean; git clean -fdx; ./configure ..." in there... sigh

Properly cleanup FileManagerListJob when folder items are deleted

This is an alternative approach to fix the issue described in
https://phabricator.kde.org/D15899

The approach used here is generic and does not require any users
of the API to know about the potential pitfalls, it actually
decreases coupling a bit!

The old approach to cleanup the list jobs only worked when we
called AbstractFileManagerPluginPrivate::removeFolder, but that
wouldn't work when a folder item gets deleted directly - e.g.
from the CMakeManager or any other code. Now, we listen to
the model signal when a row is about to be removed and cleanup
the item pointers in the list job. While doing so, we must make
take into account that the pointer may already be partially destroyed,
since only the ProjectBaseItem dtor will call takeRow, at which point
the overriden methods in ProjectFolderItem e.g. won't be available
anymore.

Additionally, it turned out that the fallback for a similar handler
of partially destroyed classes in
AbstractFileManagerPluginPrivate::jobFinished only removed the job
from a copied list, since it was using foreach, and didn't even take
the list by reference...

Finally, the test is expanded to reliably trigger the crashy behavior
explained in the review request on phabricator.
