Bug ID: 101136
Summary: ODatabaseDocument deadlocks
Product: LibreOffice
Version: 5.3.0.0.alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Base
Assignee: libreoffice-bugs@lists.freedesktop.org

deadlocked stacks
if i run the crash-testing test-bugzilla-files.py with LO 5.1.4.2,
about 10% of the documents that are "exported" are actually
copies of the source document.
this is because during the export Base deadlocks and the python
script kills it after 180 seconds. these timeout-kills are not
reported in the "crashlog" that is generated.
apparently calling ODatabaseDocument members on a non-main thread
doesn't work well because the main thread may be dispatching
some Idle or Timer at the same time that calls into Base UI,
which then may call ODatabaseDocument members.
that deadlocks because ODatabaseDocument has its own mutex.
i wonder if that can be fixed by replacing ODatabaseDocument's
own mutex with SolarMutex.
