Introduction

This release is a planned one of a working version of OpenSCADA, which are usually made at intervals of 3-4 months. The main purpose of this release is the implementation of commercial service on the OpenSCADA basis and adaptation to the ARM hardware. In addition to the main purposes within the limits of this release a great work for stabilization, cleaning the source code, as well as for the full empowerment is made.

This document is the processing (compilation) of <ChangeLog> document of the OpenSCADA system of 0.7.1 version, which is designed for briefly and clearly covering the new features and changes of the OpenSCADA system.

1 Implementation of planned tasks

In accordance with the /HomePageEn/Works/RoadMap of the release there were made the following tasks:

• Formation of the provision of commercial services based on OpenSCADA. - The concept is built and the mechanisms are created to provide commercial services by the developers based on OpenSCADA (http://oscada.org/en/services/).
• Adaptation of OpenSCADA to work on the ARM hardware platform. - The building, adaptation and full testing of OpenSCADA on the ARM architecture is made on the N800 Internet tablet of the Nokia company. (http://wiki.oscada.org/Works/Tests/ARM ). As well as private activities for adaptation:
  • SYS: Functions' prototypes TMess::put(), TMess::get(), TCntrNode::grpSize(), TCntrNode::grpId(), TCntrNode::grpAt() are changed to correct the usage of an unsigned type 'char' on the ARM as a signed.
  • SYS.TVariant, DAQ.AMRDevs, DAQ.OPC_UA: The not aligned access to data is fixed.
  • SYS.TCntrNode: The usage of an unsigned type 'char' on the ARM as a signed is fixed.
  • Archive: Functions' prototypes TArchiveS::messPut() and TArchiveS::messGet() are changed to correct variable of the message level as a signed number.
  • DAQ.JavaLikeCalc: Virtual Machine is rewritten for direct using the structures of commands to avoid alignment problems, as well as for some increasing of productivity.
  • DAQ.Siemens: The problem of the NoDave library for a global packing structures command calling '#pragma pack(1)' is fixed.
  • UI.QTCfg: The short time sleep after closing all windows in the switch off function is added. In order to provide the time for the object of all the windows to be finally destroyed and to prevent crashing.

2 Optimization, stability, sustainability and system performance increasing

During the work on this version, as well as its practical adaptation, it was discovered and corrected in a total of about 90 errors. In general, work has been done on cleaning code from the compiler's warnings with the '-Wall' flag:

• unused variables removing;
• adding the return in the all functions;
• initialization of variables with the possibility of their undefined using;
• exception of the incomplete handling of the enumeration types in the select operation;
• comparison between signed with unsigned integer.

Lets list the most significant errors correction of which significantly affected the increasing of stability:

• System-wide:
  • The command of the building system '$ make dist' is corrected and adapted to correct creation of the OpenSCADA distributions.
  • The TSYS::cron() function to call on the schedule is repeatedly corrected.
  • The variable type to store the result of the find() function, the string, is everywhere changed to the correct one 'size_t'.
  • Function: The possibility of a memory leak when attempting to set the object to a non-object function's parameter is excluded.
• Data bases:
  • DB.PostgreSQL: The handling of database address to determine the empty fields is fixed.
• Transports and protocols:
  • Transport: The loading of transports from the database is fixed, if there are records about the transport the module of which is missing.
  • Transport.Serial: Óñòàíîâëåí ôëàã O_NONBLOCK äëÿ ôóíêöèè open() ïîñëåäîâàòåëüíîãî óñòðîéñòâà ñ öåëüþ ïðåäîòâðàùåíèÿ áëîêèðîâàíèÿ îòêðûòèÿ ïîðòà íà íåêîòîðûõ USB->RS485 ïðåîáðàçîâàòåëÿõ.
