           Summary: Massive error messages and interrupting reverting of
                    multiple local changes
           Product: Fedora
           Version: 9
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: medium
          Priority: low
         Component: perl-SVK
        AssignedTo: ianburrell at gmail.com

Description of problem:
When working with svk in Fedora 9 svk throws massive error messages that seem to
be mostly harmless. This is extremely annoying since it hides real issues the
user has to care about.

The messages are (repeated several dozen to hundred times):
- When updating checkout:
Name "swig_runtime_data::type_pointer3" used only once: possible typo at
/usr/lib/perl5/5.10.0/i386-linux-thread-multi/DynaLoader.pm line 226.
Attempt to free unreferenced scalar: SV 0x934d354, Perl interpreter: 0x88fb008
at /usr/lib/perl5/vendor_perl/5.10.0/SVK/XD.pm line 1371.

- When switching to a branch:
Attempt to free unreferenced scalar: SV 0xaecf30c, Perl interpreter: 0x9d3e008
at /usr/lib/perl5/vendor_perl/5.10.0/SVK/XD.pm line 856.
	(in cleanup) panic: free from wrong pool at
/usr/lib/perl5/vendor_perl/5.10.0/PerlIO/via/dynamic.pm line 167.
Attempt to free unreferenced scalar: SV 0xaebec84, Perl interpreter: 0x9d3e008
at /usr/lib/perl5/vendor_perl/5.10.0/SVK/Inspector/Root.pm line 82.


When reverting recursively the problem occurs that reverting fails leaving the
mirror locked. To completely revert its necessary to cleanup and revert several
times (again dozens to hundred - according to the number of affected files).

Error messages are the above mentioned plus:
- Last message when reverting fails:
Attempt to free unreferenced scalar: SV 0x8e03ef4, Perl interpreter: 0x81f4008
at /usr/lib/perl5/vendor_perl/5.10.0/SVK/XD.pm line 1371.

- When trying to revert again:
Name "swig_runtime_data::type_pointer3" used only once: possible typo at
/usr/lib/perl5/5.10.0/i386-linux-thread-multi/DynaLoader.pm line 226.
/automount/wwkdev/elias/wdp already locked, use 'svk cleanup' if lock is stalled

- Cleanup (looks ok besides the "usual" message):
Name "swig_runtime_data::type_pointer3" used only once: possible typo at
/usr/lib/perl5/5.10.0/i386-linux-thread-multi/DynaLoader.pm line 226.
Cleaned up stalled lock on /automount/wwkdev/elias/wdp.

Reverting again starts from the beginning. The user is able to reproduce until
his checkout is completely reverted.


Version-Release number of selected component (if applicable):
perl-SVK-2.0.2-3.fc9.noarch

How reproducible:
Error messages and failing reverting occurs every usage.

Steps to Reproduce (error message flood):
1. use svk

Steps to Reproduce (reverting):
1. checkout
2. merge branch with changes into checkout or alter multiple files
3. revert changes recursively
  
Actual results:
Massive flood of error messages as mentioned above.
Reverting multiple files interrupts.

Expected results:
No error messages.
Reverting not interrupting.

I noticed SVK is the same Version as in Fedora 8 - only perl version has
changed. So I assume it's an issue with perl-SVK in combination with perl 5.10.
I submitted this issue related to perl-SVK since it seems to only affect
perl-SVK so far (at least for my daily usage).
