Release notes¶
When processing global transactions with several resource managers involved, and if first resource manager would return XA_RDONLY, the whole transaction would step to commit phase, instead of performing prepare for second resource manager. This could lead to data corruption.
The issue has been fixed, so that two-phase commit engine would properly prepare the other resource managers in case if some manager returns XA_RDONLY
.
