Description Barade 2011-05-21 17:16:47 UTC 
Version:           2.2 (using KDE 4.6.2) 
OS:                Linux

I clicked on the "Prune Selection" action and it deleted my whole project on my local computer (all sub directories etc.) without event showing a message box to confirm or something similar.
I don't know if that is "Prune Selection"'s usual behaviour (completely useless in my opinion, I thought it would be clean up the project more comprehensive (deleting CMake cache files etc) but you could at least show some kind of dialog before executing this action.

Reproducible: Didn't try




OS: Linux (i686) release 2.6.36-gentoo-r5
Compiler: i686-pc-linux-gnu-gcc
Comment 1 Barade 2011-05-22 13:20:23 UTC 
Found corresponding code lines:
KJob* CMakeBuilder::prune( KDevelop::IProject* project )
{
    KUrl builddir = CMake::currentBuildDir( project );
    if( builddir.isEmpty() )
    {
        KMessageBox::information(KDevelop::ICore::self()->uiController()->activeMainWindow(),
                                 i18n("No Build Directory configured, cannot clear builddir"), i18n("No clearing of builddir possible") );
        return 0;
    }
    QDir d( builddir.toLocalFile() );
    KUrl::List urls;
    foreach( const QString& entry, d.entryList( QDir::NoDotAndDotDot | QDir::AllEntries ) )
    {
        KUrl tmp = builddir;
        tmp.addPath( entry );
        urls << tmp;
    }
    return KIO::del( urls );
} 

In my opinion that is really horrible code. You should at least ask user for confirmation and maybe add some checks if URLs are temporary files and do not belong to the project since in my case I had selected my project folder as build directory.

I assume you did not use an out-of-source build directory? indeed, there this is very dangerous.

Aleix?
Comment 3 Aleix Pol 2011-05-27 17:48:48 UTC 
My only code here is the one checking there actually is a build directory configured...

And yes, that's pretty dangerous (I still think we shouldn't let the user have a in-source builddir in KDevelop).

I'll add a check to see if there is a CMakeLists.txt file then don't remove, but I'm not sure there can be some corner case where this can't be enough...

Pushed by apol into branch '4.2'.

Don't clean the build directory if it's a source dir.
