      • getLatestBuildNumber

        public int getLatestBuildNumber()
        Description copied from interface: VersionHistoryDao
        Get the highest build number from the database. This should represent what version the database thinks Confluence is running at, which in turn is used to schedule database-hitting upgrade tasks.

        If the number can not be determined (there are no versions in the database, or the version history table hasn't even been created yet) then the method will return UNKNOWN_BUILD_NUMBER. In this case, callers should assume that the database build number is identical to the configured build number.

        Specified by:
        getLatestBuildNumber in interface VersionHistoryDao
        Returns:
        the highest build number in version history table, or UNKNOWN_BUILD_NUMBER if that can not be determined.
      • getVersionHistory

        public VersionHistory getVersionHistory​(int buildNumber)
        Specified by:
        getVersionHistory in interface VersionHistoryDao
        Returns:
        the version history object associated with the build number (if there is more than one, return the latest)
      • tagBuild

        public boolean tagBuild​(int buildNumber,
                                String tag)
        We need to ensure that the checking and writing of the tag is atomic so as to prevent two or more nodes from writing the tag and reporting that it was set correctly
        Specified by:
        tagBuild in interface VersionHistoryDao
        Returns:
        true if the build number was successfully tagged, false if the tag specified has already been associated with this build number
      • finalizeBuild

        public void finalizeBuild​(int buildNumber)
        Description copied from interface: VersionHistoryDao
        Record the provided build number as finalized. This occurs when a cluster exists ZDU mode at the end of an upgrade, or is upgraded without ZDU mode.

      • addBuildToHistory

        public void addBuildToHistory​(int buildNumber)
        Description copied from interface: VersionHistoryDao
        The version history consists of a list of builds that Confluence has been successfully upgraded to
