--- Comment #13 from QA Administrators  ---
Dear Lionel Elie Mamane,

To make sure we're focusing on the bugs that affect our users today,
LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed
bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this
bug report. During that time, it's possible that the bug has been fixed, or the
details of the problem have changed. We'd really appreciate your help in
getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice
from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information
from Help - About LibreOffice.

If the bug is NOT present, please set the bug's Status field to
RESOLVED-WORKSFORME and leave a comment that includes the information from Help
- About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular
meaning that is not 
appropriate in this case)


If you want to do more to help you can test to see if your issue is a
REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your
bug pertains to a feature added after 3.3) from
https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword


Feel free to come ask questions or to say hello in our QA chat:

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team

--- Comment #4 from Lionel Elie Mamane lio...@mamane.lu ---
(In reply to comment #3)
 lionel, is this easily reproducible? ( I tried on master, just opening some
 random odb and exiting but no luck )

I got a crash-at-exit again (with master), but got no backtrace ('ulimit -c'
was 0...), and I cannot pin down specific instructions to make it reproducibly
crash.

From staring at the backtrace, I'd say it is related to the Basic IDE's
Object Catalog: for each entry, it checks whether it should delete the
entry or not. To do that, it calls HasMethod(), which tries to get the
BasicManager, which implicitly creates it.

My guess is that this is some kind of race condition between the document
disappearing, the Basic manager disappearing, and the Object Catalog checking
whether a specific Basic method is in the document. If this check happens after
the Basic manager disappears, but before the whole document disappears, then
this crash happens.

When it does not crash, I get:
warn:legacy.osl:23161:1:basic/source/basmgr/basicmanagerrepository.cxx:581:
ImplRepository::_disposing: where does this come from?
warn:legacy.osl:23161:1:basic/source/basmgr/basicmanagerrepository.cxx:581:
ImplRepository::_disposing: where does this come from?

On a crash (with unknown backtrace), I got

warn:legacy.osl:21648:1:basctl/source/basicide/bastype2.cxx:687:
TreeListBox::ExpandingHdl: no document, or document is dead!

--- Comment #5 from Lionel Elie Mamane lio...@mamane.lu ---
In particular, I notice:

basic/source/basmgr/basicmanagerrepository.cxx void ImplRepository::Notify:

   // a BasicManager which is still in our repository is being deleted.
   // That's bad, since by definition, we *own* all instances in our
   // repository.


But in my backtrace, it is notifications dbaccess::ODatabaseDocument::dispose
that lead to destruction of the BasicManager (frames 40 to 48). Oh, but this
goes via ImplRepository so should be OK, except that m_aStore contains an
*already* *deleted* BasicManager (value 0x999).

Grrr... This is confusing. At time of entrance in the loop body, we had
loop-first == xNormalizedSource.get (). But at the time of the crash,
loop-first has been deleted... Ah, actually this makes sense, since
impl_removeFromRepository has called m_aStore.erase( loop )...

I don't see any mutex in basicmanagerrepository; could this be a reentrency
issue where one thread deletes the BasicManager under the feet of the other
thread?

I wonder if the if ( !isValid() ) in criptDocument::Impl::getBasicManager
should not be if ( !isAlive() )... OTOH, in the trace, we see
m_bDocumentClosed = false. Raaah... I'm getting lost.

 I have a feeling alot of that  basic::ImplRepository stuff was introduce by
 Frank ( back in the day ) specifically for some issues relating to base (
 but I could be very much mistaken ) Is there something special you know
 about base documents that would require that ?

Possibly you are thinking of the CreationListener stuff that is used by
(and may plausibly have been created for)
dbaccess/source/core/dataaccess/databasecontext.cxx
to install the global ThisDatabaseDocument variable in scope.

I would be suspicious of this stuff also, I have seen some funny messages on
exit before regarding this ( and on my todo to look at ) Unfortunately
ObjectCatalog seems to have a raft of behaviour problems ( most recently a huge
performance hit ) but not limited to that :-(

what about valgrind, does it give anymore useful info?

With a backtrace attached it is hard to deny there is no crash/issue :-).
Hopefully it doesn't crash that often. If can reproduce it more often and can
provide steps, please do :).

Kind regards,
Joren
