Bug ID: 165202
Summary: Database - Mutex lock / race condition requiring force
kill and restart
Product: LibreOffice
Version: 25.2.0.3 release
Hardware: All
OS: macOS (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Base
Assignee: [email protected]
Reporter: [email protected]
Description:
Ever since moving to 25.2.0.3 (AARCH64), I can reproducibly get a mutex lock in
Base requiring a forced kill exit and restart.
1) The database connection is to a mysql backend using the direct (native)
connector.
2) On screen, I display the main base window, and then open a table for direct
editing of data.
3) I set a filter on the table to select a subset of records.
4) I edit one or two fields of a given record, and then validate those entries.
5) I then try to remove the filter, i.e. set it back to displaying all of the
records.
6) At this point, LO goes into spinning beachball mode, and I'm required to
force kill the application.
7) The Apple trace that is produced at the moment the LO process is terminated
is enclosed.
It appears to show a concurrent mutex lock, or race condition, caused by an
XAccessible listener:

This does not occur with LO 24.8. ==> regression
Steps to Reproduce:
See description above
Actual Results:
Concurrent mutex locks causing hang, and requiring forced kill
Expected Results:
Shouldn't hang, the filter removal should return gracefully to the default grid
control table resultset display.
Reproducible: Always
User Profile Reset: Yes
