Description H.-P. Sorge 2016-01-28 21:40:39 UTC 
Description of problem:
KWin segfaults (during, after?) login. 
The Bugreporting tool pops up.
I start the backtrace.
GDB stops at ----->
0x00007f34f29a27ad in nanosleep () at ../sysdeps/unix/syscall-template.S:84
84      T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
Missing separate debuginfos, use: dnf debuginfo-install bzip2-libs-1.0.6-19.fc23.x86_64 flac-libs-1.3.1-5.fc23.x86_64 krb5-libs-1.14-5.fc23.x86_64 libgcc-5.3.1-2.fc23.x86_64 libstdc++-5.3.1-2.fc23.x86_64
<-----------
However the debug modules are installed!!!!!.

try to fix by ....
first: "dnf remove" all debugsymbol-rpms 
second: boot/login reproduce bug
third: reload the debugsymbols as requested by gdm
fourth: GDM then ends with the obove mentioned request:  
" Missing separate debuginfos, use: dnf debuginfo-install ..."


Version-Release number of selected component (if applicable):
kwin-common-5.5.3-1.fc23.x86_64
kf5-kwindowsystem-debuginfo-5.18.0-1.fc23.x86_64
kwin-libs-5.5.3-1.fc23.x86_64
kwin-5.5.3-1.fc23.x86_64
kf5-kwindowsystem-5.18.0-1.fc23.x86_64
kwin-debuginfo-5.5.3-1.fc23.x86_64
gdb-7.10.1-30.fc23.x86_64

How reproducible:
boot.

Steps to Reproduce:
1. boot
2.
3.

Actual results:
I need to boot the system three times!!!
 first time boot/login : no window frames on any restored window and no taskbar.
 second time boot/login: no taskbar
 third time boot/login:  so far working   
 The desktop is being show shortly during login. 
 Then the login progress is shown.
 Then the windows are being restored and the KWin segfaults.       
 The debug tool can be started.
 GDB does not complete.
 The debug tool does not handle the report. 

Expected results:
 1. flawless boot 
 2. Keep debug tool functional even if trace back fails 

Additional info:
 New user has same effect.
Comment 1 Rex Dieter 2016-01-29 13:52:36 UTC 
Clearly gdb is confused here, both about not generating a backtrace and claiming that -debuginfo is missing when it really isn't.

I'm not sure there's much we can to to diagnose this on kwin side without a backtrace or otherwise any other additional useful information.

Feel free to reopen (and reassign to gdb is you want the first part assigned to gdb maintainer) or if you ever can get a useful backtrace.
Comment 2 H.-P. Sorge 2016-01-29 14:19:30 UTC 
Rex - thank you for comment. 

I reassigned it to gdb.
Comment 3 Jan Kratochvil 2016-01-31 14:54:41 UTC 
I do not see what you really debugged with GDB, the Component was kwin so I expect:
$ gdb -p `pidof kwin`

Missing separate debuginfos, use: dnf debuginfo-install kwin-5.5.4-1.fc23.x86_64
->

And I get the backtrace(s) fine:

KWin Crash Screen

it's the bottom buttom - Fehlersuche in gdb - that leads to the failing trace.
Comment 5 H.-P. Sorge 2016-01-31 16:53:25 UTC 
My initial starting point was KWin - please see the attached screen shot.

But you are right it's not KWin having Debug trouble it's kwin_x11!

Did you run the command
  dnf debuginfo-install bzip2-libs-1.0.6-19.fc23.x86_64 flac-libs-1.3.1-5.fc23.x86_64 krb5-libs-1.14-5.fc23.x86_64 libgcc-5.3.1-2.fc23.x86_64 libstdc++-5.3.1-2.fc23.x86_64
from your shell as root?  I do not recognize if the crash screenshort from Comment 4 is from ABRT or some other tool.

Did you run the "bt" (or "backtrace") command?  What did it (did not) show?

If you did run the command and GDB still asks for "dnf debuginfo-install" then reassign this Bug to: dnf-plugins-core

If you did not run the command and the Comment 4 dialog is from ABRT then reassign this Bug to "abrt" as ABRT should handle debuginfo-install on its own.

If you did not run the command and the Comment 4 dialog is from a different tool (something from KDE) then reassign this Bug to that tool as that tool should handle debuginfo-install on its own.
Comment 7 H.-P. Sorge 2016-01-31 21:03:39 UTC 
At least we agree, that this case deserves a bug report.

1. KWin bug report pops up during sign-in. 
2. The button ()Fehlersuche in gdb  starts gdb 
3. Tha trace fails as shown before.

4. I use<.  gdb -p `pidof kwin_x11` > that failed.
5. I use<   gdb -p   2673           > that recreated the failing trace.

6. yes, I did run the dnf debuginfo-install ....
 the output - as always:

Comment 8 Jan Kratochvil 2016-01-31 21:12:20 UTC 
Have you done also:
  dnf distro-sync
?
As you may have older binary packages than what debuginfo packages got installed:
  rpm -q krb5-{debuginfo,libs}.x86_64
I see that current F-23 package is krb5-libs-1.14-7.fc23.x86_64 but you seem to run krb5-libs-1.14-5.fc23.x86_64.  Fedora does not provide debuginfos for non-latest packages.

Still that is also a dnf/rpm Bug but a more general one existing since forever.  Maybe now with the new dnf package manager it could be finally fixed: Bug 432806
Comment 9 Honza Silhan 2016-02-01 13:16:38 UTC 
It will be fixed soon whether the problem is in bug 1024701.

Created attachment 1120165 [details]
All gdb output from gdb and dnf for kwin_x11 debugging.

I run dnf distro-sync (it failed before - an other story).

I did the debugging from scratch. 
The same gdb problem persists.

The attached output from the debug cycles has comments within.

Comment 11 Jan Kratochvil 2016-02-01 17:03:13 UTC 
The problem (if it gets accepted as a problem) is:

# dnf debuginfo-install bzip2-libs
Nothing to do.
# dnf debuginfo-install bzip2
Installing: bzip2-debuginfo
Is this ok [y/N]: n
# rpm -q --qf '%{sourcerpm}\n' bzip2 bzip2-libs.x86_64
bzip2-1.0.6-19.fc23.src.rpm
bzip2-1.0.6-19.fc23.src.rpm

yum debuginfo-install properly installed %{sourcerpm}-debuginfo.rpm.
dnf debuginfo-install only appends "-debuginfo" to its argument so it does not work for subpackages.

There exist packages which have PKG-debuginfo but there is no PKG, only some PKG-subpackages.  For example "dhcp".

GDB can change the suggestion but still I believe the original yum behavior was more convenient - one can use the installed RPM package name and not to construct it from %{sourcerpm} stripping ".src.rpm" and adding back arch all by hand.

Also debuginfo-install does not do much work, one can just append "-debuginfo" (and prepend --enablerepo='*debug*').
Comment 12 H.-P. Sorge 2016-02-01 20:42:31 UTC 
OK - gdb looks for those debuginfo rpms in a wrong place or the packages were not provided? 

gdb requests:  
Missing separate debuginfos, use dnf debuginfo-install bzip2-libs-1.0.6-19.fc23.x86_64 flac-libs-1.3.1-5.fc23.x86_64 libgcc-5.3.1-2.fc23.x86_64 libstdc++-5.3.1-2.fc23.x86_64

In this case, no debuginfo rpms are found:
!!! dnf list | grep -e 'bzip2\|flac\|libgcc\|libstdc++' | grep debug 
... NOTHING ...

I try:
dnf debuginfo-install bzip2  flac  libgcc  libstdc++
........ 
Installed:
  bzip2-debuginfo.x86_64 1.0.6-19.fc23
  flac-debuginfo.x86_64 1.3.1-5.fc23

Which is funny - see !!! above. How come dnf does not list them????
At least two packages made it.

And it looks like I run into some "undocumented feature"
dnf debuginfo-list
no such command ...

This does the job...
dnf list --enablerepo=updates-debuginfo  --enablerepo=fedora-debuginfo | grep -e 'bzip2\|flac\|libgcc\|libstdc++'| grep debug
giving bzip2 and flac debug info.

(I'd like much more: dnf debuginfo-list :-)

Still missing are debuginfos for libgcc and libstdc++.
So - please let me know the repository where those two 
debug packages are hiding......

For libgcc and libstdc++ you should have used debuginfo package 'gcc':

$ rpm -q --qf '%{sourcerpm}\n' libgcc.x86_64 libstdc++.x86_64
gcc-5.3.1-2.fc23.src.rpm
gcc-5.3.1-2.fc23.src.rpm
Comment 15 H.-P. Sorge 2016-02-02 21:26:21 UTC 
Sorry that I keep bugging you -

I have downloaded the source package, applied the patches, added  
dnf install gmp*
dnf install mpfr-devel.x86_64
dnf install libmpc-devel.x86_64

./configure --enable-multilib

but make fails with 
Makefile:22461: recipe for target 'stage1-bubble' failed

First: Do I have to compile gcc from source and install it??
       Overwriting actual binary gcc rpm?? 
Second: You say "you should have used debuginfo package 'gcc':"
       however gcc-5.3.1-2.fc23.src.rpm seems not have the proper files:

In gcc.spec I see the references to debuginfo and I run
--------------
[root@joyw520 GCC]# export RPM_BUILD_ROOT=gcc-5.1.1-20150618
[root@joyw520 GCC]# /usr/lib/rpm/find-debuginfo.sh 
extracting debug info from gcc-5.1.1-20150618/libgo/go/debug/elf/testdata/gcc-amd64-linux-exec
Dest dir longer than base dir is not supported
--------------
Will this be fixed with the "duplicate"??

To me it looks like a gcc dependency that rests beyond a simple 
dnf debuginfo-install

Some advice is appreciated on how to proceed from here to get the 
debug symbols for gcc activated. 

Thank you for your patience.

Compiling anything from source is offtopic for this Bug.
But when you ask you should run yum-builddep on gcc-*.src.rpm if you try to compile anything yourself from sources.


> First: Do I have to compile gcc from source and install it??

Nobody asked you for that and overwriting any binaries from rpm is always a wrong thing to do.


> Second: You say "you should have used debuginfo package 'gcc':"
>        however gcc-5.3.1-2.fc23.src.rpm seems not have the proper files:

I meant to install:
  gcc-debuginfo-5.3.1-2.fc23.x86_64.rpm
GCC package is a special case of debuginfo where you also need:
  gcc-base-debuginfo-5.3.1-2.fc23.x86_64.rpm


> In gcc.spec I see the references to debuginfo and I run

That is unrelated to this Bug.

No.  This error will not happen if you properly use Koji or Mock.  But that is unrelated to this Bug.  /usr/lib/rpm/** are internal rpm tools and files.

dnf debuginfo-install gcc


> Thank you for your patience.

It is unfortunate the Fedora debuginfos do not work too well for users.
