    • Type: Task

    • Affects Version/s: None
    • Fix Version/s: QualifiedToSchedule
    • Component/s: Core

      Description

      Currently Nuxeo persistence layer has to handle several scenarios :

      • XA mode : the orginal mode that is here since the beginning
      • SingleDS mode : used by default since 5.8, a shared DataSource is used by all services in transactional mode
      • no TX / Auto-Commit : this mode is used only in tests

      Having these 3 modes creates :

      • complex code
      • problems that are specific to one mode only
        • typically the SingleDS mode has problems in some cases like NXP-13486
      • fake problems : the problems we have in non-transactional tests are not real problems
        • at least they are not problems we want to invest time in

      The target solution is :

      • fix the singleDS mode
      • share as much as possible code between XA and SingleDS
      • get ridd of the autocommit mode
