StateTransfer's PutKeyValueCommand may trigger remote get

    XMLWordPrintable

Details

    Description

      In TX mode with write skew check on, ST executing puts may trigger a remote get.
      The condition in TxDistributionInterceptor.handleTxWriteCommand should probably be switched from

      if (ctx.isOriginLocal() && !skipRemoteGet || command.isConditional() || shouldFetchRemoteValuesForWriteSkewCheck(ctx, command))
           remoteGetBeforeWrite(ctx, command, recipientGenerator);
      

      to

      if (!skipRemoteGet && (ctx.isOriginLocal() || command.isConditional() || shouldFetchRemoteValuesForWriteSkewCheck(ctx, command)))
           remoteGetBeforeWrite(ctx, command, recipientGenerator);
      

      EDIT:
      I have also registered a situation where the Prepare/Commit command was executed remotely from within the ST because the topology has changed during the remote get. This should be avoided as well.
